*Advantages of Absorption chillers
The cooling process by a chiller in modern air
conditioning systems marking comfort conditions
with clean & fresh air for people who live in crowded
& polluted cities & also for most of industrial
applications plays very Important role. In this regards
the LiBr + H2O absorption chillers with coefficient
of performance (COP) greater than 0.7 because of
following characteristics & many other reasons are
more advisable than compression Chillers.

Seawater
Piping system
It is possible to locate the chiller in the basement on the same level, on the �oor for it is
safety & proper operation with the feature of little vibration & low noise . It is
recommended that the chiller machine room should be separated from boilers &
Pump Rooms as possible. Well ventilation of machine room is strongly recommended.
The Chillers foundation must be on a higher level with load capacity as 1.5 times the
Operation Weight in the machine room.
To decide the quantity , you should take cooling capacity , cooling capacity �uctuating,
Building function ,installation site & economic factors in to consideration .You need not
consider the stand by unit because continuous operation is better for the life time than
intermittent operation , but in high cooling capacity chillers with stand by Canned
pumps may be suggested.
If your machine room or entrance is smaller than the mentioned dimensions ,please
contact Azar Nasim to discuss for a solution and nally chiller dimensions Are
adjustable.
If it's limited by transportation or machine room entrance height, split shipment shall
Be selected.
Provide chilled water at 32[°F] for special processing requirements .For example
food and fruit plant , medical plant ,power station cooling system ,etc...
Use seawater as cooling water, applications to coastal buildings, ship's air conditioning
& seawater desalination plant.
1. Soft connector must be installed at inlet / outlet of chilled, cooling, & hot water. The
weight of the piping system can never be borne by the chiller.
2. Cooling tower must be equipped with a protective screen to prevent foreign matters
From entering the cooling water system.
3. The cooling tower must be far away from heat resource & dust resource.
4. No pipes or valves must hang over the chiller to prevent the chiller from being
Damaged during installation, maintenance, or valve leakage.
* Technology Extension

Selection Information
General
Cooling Capacity is tabulated for all chiller
models at a variety of conditions to cover most
comfort
Cooling and industrial system requirements. The
water cooled ANCH-W series are rated over a
range of Leaving water temperatures of 42 ˚F to
46 ˚F and condenser leaving water temperatures
of 85 ˚F to 105 ˚ F . The ANCH-A series are rated
over the same evaporator chilled water range at
condensing Temperatures of 115 ˚F to 135 ˚F.
Chilled water quantity and range:
Required cooling capacity and the desired chilled
water range are the two important factors in
determining the amount of water to be circulated
in the evaporator. This flow rate in (GPM) is given
in the performance data tables.
The Flowing formula can also be used when
needed.
GPM =
Tons × 24
Chilled water range (ΔT) {˚F}
Water cooled chiller (ANCH-W) series:
A 10 ˚F condenser water range is generally
the best compromise for the most economical
cooling tower selection to satisfy the chiller
requirements. Based on the above suggestion
and referring to performance data tables under
different condenser leaving water temperatures,
we can extract the required condenser water flow
rate are in (GPM) and the water side pressure
drop (PD) . Refer to the Azar Nasim cooling
tower catalogue for an appropriate cooling tower
selection.
Condenser water temperature and heat
pressure control:
Since cooling towers are used in conjunction
with water cooled condensers, the available
condenser water temperature available shall
be at least 5 ˚F above the ambient wet bulb
temperature. For example if the ambient wet bulb
temperature is 80 ˚F, a properly sized tower will
provide 85 ˚F Condenser water temperatures.
For proper operation of a reciprocating water
cooled chiller, it is necessary to maintain a
condenser leaving water
temperature not lower than 85 ˚F. This means
that a method of head pressure control such as
controlling cooling
tower fan via a thermostat or using a condenser
water regulating valve in order to control the
condenser water flow rate shall be employed.
Air cooled chiller (ANCH-A) series:
ANCH-A units require the use of remotely located
air cooled condensers. The column headed QC in
the performance
data tables show the required THR capacity at
each condensing temperature condition. Refer to
the Azar Nasim air cooled condenser catalogue
for an appropriate condenser selection.
Head pressure control and winter start in air
cooled chillers:
Air cooled condensers used with chillers must
always include an accurate method of controlling
the condensing pressure at 185 (psig) or higher.
It is also necessary to determine the minimum
outside air temperature at which the system will
be operated. At an ambient temperature below
55 ˚F, a winter start system should be furnished
with the condenser to enable the chiller to start
without any difficulty.

Selection procedure
Water cooled models:
Given:
Water flow rate to be chilled = 110 GPm
Design chilled water range = 10˚F
Evaporator leaving water temp. = 45˚F
Design condenser water range = 10˚F
Condenser leaving water temp. = 95˚ F
From the corresponding performance data
table (Evap. Lvg. Water temp. = 45 ˚F) we select
unit ANCH-70-2-A, offering 52.2 tons at 120˚F
condensing temp. From the same table we
extract the evap water flow rate of 125 (GPM) and
PD of 17.2 (ft². in.wg) for ΔT = 10 ˚F.
Determine unit model and size:
Required cooling capacity:
We can also extract the condenser THR capacity
of 808.7 MBH. With this valve, refer to Azar Nasim
air cooled condenser catalogue and selected the
required unit or units.
Qe = GPM × Chilled water range = 110 × 10 =

From the corresponding performance data
table (Evap. Lvg water temp. = 45 ˚F) we select
unit ANCH-60-2-W, offering 46.3 tons at 95 ˚F
condenser leaving water temperature. From the
same table we extract the evap. Water flow rate
of 110.8 GPM and P.D. of 12.8 (ft² .in.wg) for ΔT =
10 ˚F.
We can also determine the condenser water flow
rate of 135.1 (GPM) and PD of 7.1 (ft² .in.wg),
which the condenser (GPM) valve given above ,
refer to Azar Nasim cooling tower catalogue and
select the required unit or units.

FRP AND GALVANIZED COOLING TOWER
1. Definition:
Cooling towers are heat removal devices
used to transfer process waste heat to the
atmosphere. Cooling towers may either use
the evaporation of water to remove process
heat and cool the working fluid to near the
wet-bulb air temperature or in the case
of "Close Circuit Dry Cooling Towers" rely
solely on air to cool the working fluid to
near the dry-bulb air temperature. Common
applications include cooling the circulating
water used in oil refineries, chemical plants,
power stations and building cooling. The
towers vary in size from small roof-top units
to very large hyperboloid structures that can
be up to 200 meters tall and 100 meters in
diameter or rectangular structures that can
be over 40 meters tall and 80 meters long.
Smaller towers are normally factory-built,
while larger ones are constructed on site.
They are often associated with nuclear power
plants in popular culture, although cooling
towers are constructed on many types of
buildings.
2. Classification by use:
HVAC
An HVAC (Heating, Ventilating, and Air
Conditioning) cooling tower is a subcategory
rejecting heat from a chiller. Watercooled
chillers are normally more energy efficient
than air-cooled chillers due to heat
rejection to tower water at or near wet-bulb
temperatures. Air-cooled chillers must
reject heat at the dry-bulb temperature, and
thus have lower average reverse-Carnot
cycle effectiveness. Large office buildings,
hospitals, and schools typically use one
or more cooling towers as part of their air
conditioning systems. Generally, industrial
cooling towers are much larger than HVAC
towers.
Industrial cooling towers
Industrial cooling towers can be used to
remove heat from various sources such
as machinery or heated process material.
50
The primary use of large, industrial
cooling towers is to remove the heat
absorbed in the circulating cooling water
systems used in power plants, petroleum
refineries, petrochemical plants, natural
gas processing plants, food processing
plants, semiconductor plants, and for other
industrial facilities such as in condensers
of distillation columns, for cooling liquid
in crystallization, etc. The world's tallest
cooling tower is the 200 meter tall cooling
tower of Niederaussem Power Station.
3. Heat transfer methods
With regard to the heat transfer mechanism
employed, the main types are:
Wet cooling towers or simply open circuit
cooling towers operate on the principle
of evaporation. The working fluid and the
evaporated fluid (usually H2O) are one and
the same. Dry Cooling Towers operate
by heat transfer through a surface that
separates the working fluid from ambient
air, such as in a tube to air heat exchanger,
utilizing convective heat transfer. They do not
use evaporation.
4. Air flow generation methods
With regard to drawing air through the tower,
there are three types of cooling towers:
Natural draft, which utilizes buoyancy via
a tall chimney. Warm, moist air naturally
rises due to the density difference to the dry,
cooler outside air. Warm moist air is less
dense than drier air at the same pressure.
This moist air buoyancy produces a current
air through the tower. Mechanical draft,
which uses power driven fan motors to force
or draw air through the tower. Induced draft:
A mechanical draft tower with a fan at the
discharge which pulls air through tower. The
fan induces hot moist air out the discharge.
This produces low entering and high exiting
air velocities, reducing the possibility
of recirculation in which discharged air
flows back into the air intake. This fan/fin
arrangement is also known as draw-through.
Forced draft: A mechanical draft tower with a
5. Air-to-water flow Categorization
Cross flow
Cross flow is a design in which the air flow is
directed perpendicular to the water flow (see
diagram below). Air flow enters one or more
vertical faces of the cooling tower to meet
the fill material. Water flows (perpendicular
to the air) through the fill by gravity.
The air continues through the fill and thus
past the water flow into an open plenum
area. A distribution or hot water basin
consisting of a deep pan with holes or
nozzles in the bottom is utilized in a cross
flow tower. Gravity distributes the water
through the nozzles uniformly across the fill
material.

In a counter flow design the air flow is directly

is sprayed through pressurized nozzles and flows
downward through the fill, opposite to the air
flow.

FAN

blower type fan at the intake. The fan forces
air into the tower, creating high entering
and low exiting air velocities. The low
exiting velocity is much more susceptible to
recirculation. With the fan on the air intake,
the fan is more susceptible to complications
due to freezing conditions. Another
disadvantage is that a forced draft design
typically requires more motor horsepower
than an equivalent induced draft design. The
forced draft benefit is its ability to work with
high static pressure. They can be installed
in more confined spaces and even in some
indoor situations. This fan/fill geometry is
also known as blow-through.

DRY AIR IN
COLLECTION BASIN
COUNTERFLOW TYPE DESIGN
Common to both designs
The interaction of the air and water flow allows
a partial equalization and evaporation of water.
The air, now saturated with water vapor, is
discharged from the cooling tower. A collection
or cold water basin is used to contain the water
after its interaction with the air flow. Both cross
flow and counter flow designs can be used
in natural draft and mechanical draft cooling
towers.
51
and the range from below equation:
Cooling tower load (KW) =
flow rate (L/S) ×4.19 (Kj/KgºK)×Range(ºK)
Approach - The approach is the difference
in temperature between the cooledwater temperature and the entering-air
wet bulb temperature (twb). Since the
cooling towers are based on the principles
of evaporative cooling, the maximum
cooling tower efficiency depends on the
wet bulb temperature of the air. The wetbulb temperature is a type of temperature
measurement that reflects the physical
properties of a system with a mixture of a gas
and a vapor, usually air and water vapor.
8. Principal of operations of "Tahvieh
Azar Nasim" conical Type Cooling Towers
The automatic rotating sprinkler system
distributes the hot water evenly over the
entire fill section. Dry air is simultaneously
drafted upward causing evaporation and so,
the heat is removed. The cooled water falls
into the basin and is pumped to the heat
source for recirculation.
9. Thermal Design
The "Tahvieh Azar Nasim" cooling towers
operate on the counter flow principle which
gives the best performances. The air flow
through the tower fill is opposed the water
flow. The cold air meets the closed water
at the bottom of the fill providing maximum
evaporation and heat transfer in the fill. The PVC
fill is corrugated with clear channels between
flutes to prevent any blockage and giving a
large surface area per unit volume. Water
flows through the fill in a thin film exposed the
maximum area to the cooling air flow. The flutes
of the fill area at an angle and each layer of fill
section are reversed, turning the film or water
and air over for maximum cooling.
10. Better Air Flow
The rotating water sprinkler head distributes
the hot water which forming a fine spray,
52
and hence does not need the conventional
type of moisture eliminator. This is because
the water header has large number of holes
giving a steam type flow direct into the
fill. Tower with fixed nozzles cannot obtain
the coverage, which is needed for optimum
cooling. We should not overlook that in
rectangular type towers, eliminators provide
a pressure drop which evens out the flow
particularity into the corner.
The "Tahvieh Azar Nasim" cooling tower
being round, plus its conical fan inlet can
better provide an even air flow through the
fill, with a lower pressure drop, and without
the additional pressure drop caused by the
eliminator needed on other towers. Fan
KW depends on the mass of air delivered,
the pressure generated and the blade
efficiency, from the available data on other
manufacturers' tower. Tahvieh Azar Nasim
air volumes are similar to competitor s size.
The influence factors for lower power are
pressure and efficiency .
Tower has large air inlet area, with low
air velocity; low pressure drop tower is of
the induced draft type. The fan is in the
ideal position, to discharge the air at a
high velocity upwards and allow natural
convection to prevent recirculation, as
can happen with the forced draft tower
arrangement, where air leaves the eliminator
at low velocity.
11. Pumping head
As seen already, the water distribution by
a rotating header is a significant part of the
Tahvieh Azar Nasim tower design. The
large diameter holes in the rotating header
give a gentle stream of water at negligible
pressure lose. Also, there is no risk of
clogging , as can easily happen with spray
nozzles in other types of towers. The Tahvieh
Azar Nasim cooling towers pumping head,
is the static height of the spray or header
pipe above the water level in basin, plus the
pressure loss the rotating header, sprays
of balancing valves, according to the type of
tower being considered. It should be noted
that pumping heads quoted for Tahvieh Azar
Nasim towers include both of these as well
as piping inside the pressure loss of sprays
is usually quoted. To this must be added the
static lift to the spray header from the basic
required for a Tahvieh Azar Nasim cooling
tower 50% less than for some other cooling
towers.
12. Lift factor
Although we generally refer to the towers
as being constructed of fiberglass, we
should actually refer to them as being FRP
(Fiberglass Reinforced Plastic) should not
be confused with the translucent fiberglass
roofing panels, and in particular with the
cheaper grades which have given poor
results even only in a few years.
Without an adequate protective layer,
the sun s ultra violet rays draw the fibers
upwards so that hairs appear to be growing
on the panels as with fiberglass hulls, the
Tahvieh Azar Nasim towers do not need
painting. However, if a client wishes to have
color scheme changed, painting is possible.
Compared with timber towers which will
ultimately rot, or steel towers which will
rust despite increased maintenance, the
fiberglass tower has tremendous financial
advantages for the wise investor.
Unfortunately, many buyers appear to be only
concerned to maintenance, running costs or
rate of deterioration.
13. Smaller Fan Motors
Smaller electric motor in "Tahvieh Azar
Nasim "cooling towers, causes lower
consumption power and save money.

15. Components
The various components of FRP conical type
cooling tower are as below:
Casing
The bolt together FRP casing is completely
non-corrosive. The casing enclosed the PVC
fills services to isolate the air stream, which
passes over the fills. The casing is conical
shaped to reduce frictional resistance of
air and aids flow pattern. It is designed to
withstand wind loads up to 75km/hr., and
vibrations emanating from the motor and
other equipment. FRP casing has a high
impact resistance when laminated with
Isophetalic Resin and even if damaged is
easily repaired at site. The neopentyl glycol
gel coat is U.V. inhibited to provide a long
lasting finished appearance and service
life and imported wax release agents helps
retain colors for long periods even if exposed
to direct sunlight. The casing is in sections
of easy to handle sizes and is assembled at
site using bolting joints. The conical shape
of casing is ideal with regard to cooling
efficiency and space economy.
Basin
The basin serves the purposes of collecting
the water descending from the fills and
channeling it to the suction point. Further the
basin also acts as a reservoir of water. The
basin is also made of FRP and has similar
characteristic the same as casing.
Sump
The sump is located below and in the center
of the basin and has all connections for inlet/
53
outlet, drain, filling and overflow. The unit is
at the lowest point and is always flooded and
thus ensuring no capitations on the pump
suction. The suction tank is fully molded in
FRP to prevent corrosion and subsequent
leakages. A drain is provided to the tank
which makes it quite simple to remove the
accumulated dirt and to drain out the water,
simplifies the cleaning and maintenance of
the tower.
Tower Structure
The structure of the tower supports the
casing, basin and motor mounting loads to
the foundations. These are of MS and are hot
dipped galvanized so as to resist corrosion.
Fills
The fills section is designed to bring about
intimate contact of water and air so as to
facilitate heat and mass transfer at the same
time aiding in proper and even distribution
of air and water over the cross section,
while maintaining minimum pressure drop.
The fills are of honeycomb section and are
vacuum formed from anti-bacterial Virgin
PVC for excellent resistance to corrosion and
give maximum area for intake.
Sprinkler
The gravity die cast aluminum alloy / S.S
sprinkler is used to distribute the water
evenly over the cross section of the tower.
An aluminum alloy / S.S rotary head with
radial PVC / PP pipes having drilled holes
serves this purpose. The rotation of assembly
is accomplished due to reaction of water
jet being sprayed from PVC / PP pipes. The
sprinkler head is mounted on top of the
central water supply. To ensure free rotation
even at low flows the sprinkler has 2 sealed
pre lubricated ball bearing mounted on
the central shaft. This sprinkler system
is preferred over the fixed nozzle system
forVarious reasons.
Fan / Fan Blades
The light weight fan has good corrosion-
54
resistant quality is an axial flow, multi
blade version with adjustable blade
pitch. The fan is designed to deliver large
volumes of air at low power consumption
and low noise generation. The fans
are dynamically balanced for smooth
operation, longer bearing life including
that of the supporting structure. FRP fan
blades may also be provided on demand
and these have in addition to excellent
corrosion-resistance, good noise reduction
properties.
Fan Drive Motor
The fan drive motor is in IP-55 F class
design. The fan is directly driven by the
special extended shaft motor made from
steel mounted facing downward on a
mounting frame on the top of the Cooling
Tower.
Louvers
FRP louvers are installed at the air inlet
(space between the Tower casing and
water Basin) to prevent water splash and
contaminants like leaves, bird etc. entering
the Cooling Tower.
Grills
Since Cooling Tower are generally installed
on windswept rooftop or higher altitude,
galvanized MS grill are installed at the air
outlet to prevent contaminants like leaves,
bird etc. entering the cooling tower.
16. Water loss
Water losses are very important especially in
dry zones. Water losses in cooling towers are
based on four items;
•
•
•
•
Evaporation
Drift
Bleed off
Pipe line and valves leakages
Evaporation
The evaporation rate can be estimated from
the below equation:
E=0.0008(Ti-To) ×F
E=evaporation rate (gpm)
Ti &To= inlet and outlet temperatures °F
F= water flow rate (gpm)
Drift
Water droplets that are carried out of the
cooling tower with the exhaust air. Drift
droplets have the same concentration
of impurities as the water entering the
tower. The drift rate is typically reduced by
employing baffle-like devices, called drift
eliminators, through which the air must
travel after leaving the fill and spray zones
of the tower. Drift can also be reduced
by using warmer entering cooling tower
temperatures. The drift loss in Tahvieh Azar
Nasim cooling towers is less than 0/002%
of water flow rate, so the maximum drift loss
can be calculated from below equation:
D=0.002×F
Bleed Off
The portion of the circulating water flow that
is removed in order to maintain the amount
of dissolved solids and other impurities at an
acceptable level. It may be noted that higher
TDS (total dissolved solids) concentration in
solution results in greater potential cooling
tower efficiency. However the higher the TDS
concentration, the greater the risk of scale,

Drift Eliminators
Units with rotary sprinklers are designed to minimum carry over by judicious
choice of air flow velocities. The air distribution is aided by using a centrally
located rotating eliminator section to avoid high velocity area. Further the pipes
are covered by aero foil section eliminators which prevent small droplets escaping
and facilitate uniformly distributing the sprinkler water. For the towers using
stationary sprinkler nozzles a full width eliminator covering the full cross section
is used. The shape of the eliminator is chosen to minimize pressure loss of air
and to trap the maximum amount of droplets.

biological growth and corrosion.
Tahvieh Azar Nasim suggested the flowing
rates for bleed off as given in below table:
Bleed off can be calculated by multiplying
water flow rate into the coefficient given
above. Bleed off pipe should be installed on
return pipe from condenser to cooling tower
and near the tower so that when the pump is
running bleed off takes place.
Pipe line and valves leakage
Water losses from pipe lines and valves are
depends on the quality and connections.

30. Provide bottom support for ladder.
31. Sprinkler assembly
31-1- sprinkler pipes
The sprinkler pipes must be clean to prevent
any blockage in their holes. When cleaning
the sprinkler pipes, loosen the lock nut to
unscrew and remove the sprinkler pipes. On
reassembling, be sure the alignment screws
(round head) are positioned at the top center
30-2 sprinkler hand Scale or sludge attached
to the narrow space impedes revolution.
57
If the sprinkler rotation slows down or
even stops despite normal water flow the
sprinkler pipes or, at the beginning of the
season, if the head does not rotate even
though the water is flowing at the same rate
as last season, dismantle the rotary head for
cleaning and checking.
When reassembling, do not wet the
bearing portion with water and apply ample
anticorrosion lubricant (water proof, lithium
soap- radical grease) on bearings and oil
seals position.
Also pay particular attention when passing
the oil seal over the center poll to not to
damage the lips of the oil seal. Since oil seal
is effective for a limited period, it is desirable
to dismantle and replace it every two or three
years.
18. Normal conditions
Water quality and environmental conditions
on the vast majority of HVAC cooling tower
applications permit acceptable service life
from standard cooling tower construction
using the materials previously described.
Significant deviation from these normal
conditions often demands alternate
materials choices.
For most proposes the following criteria
define normal conditions:
Standard tower design assumes a maximum
of 120°F hot water to the tower, including
system upset conditions. Temperatures
over 120°F, even for short duration, may
impose damaging effects on PVC fill, many
thermoplastic components, galvanizing
and play woods. Those rare applications
demanding hot water in excess of 120°F
usually benefit from careful review with
the tower manufacturer to assure that
appropriate materials changes from standard
configuration are included in the initial
purchase specification.
Normal circulating water chemistry
falls within the following limits (note the
distinction between circulating water and
make-up water):
--ph. between 6.5 and 8.0, although ph. down
58
to 5.0 is acceptable if no galvanized steel is
present. Low ph. attacks galvanized steel,
concrete and cement products, fiberglass
and aluminum. High ph. wood, fiberglass and
aluminum.
--chlorides (express as NaCl) below 750 ppm.
--Calcium (as CaCO3) below 1200 ppmexcept in arid climates where the critical
level for scale formation may be much lower.
--sulfates below 5000 ppm if calcium exceeds
1200 ppm sulfates should be limited to 800
ppm, (less in arid climates) to prevent scale
formation.
--sulfides below 1ppm
--Silica (as SiO2) below 150 ppm
--iron below 3ppm
Manganese below 0.1ppm
-- saturation index between -0.5 and +0.5
negative LSI indicates corrosion likely;
positive indicates CaCo3 scaling likely.
--suspended solids below 150ppm if slides
are abrasive avoid film-type fills, is solids
are fibrous, greasy, fatty or tarry wood, PVC,
Polypropylene or ABS fills can be used, but
PVC usually is the material of choice.
--oil and grease below 10ppm or loss of
thermal performance will occur.
--no organic solvents
--no organic nutrient, which could promote
growth of algae or sludge.
--chlorine (from water treatment below
1ppm free residual for intermittent treatment
below 0.4ppm free residual for continuous
chlorination These conditions define normal
circulating water, including the chemical
concentrating effects caused by recalculating
the water to some predetermined number of
concentration.
19. Water quality control
Cooling towers not only are very effective
but also sensitive air washers. Atmospheric
dust able to pass through the air inlet will
enter the circulating water or air pollution,
such cases as corrosion, scale and algae
growth which impeded the performance of
air conditioning equipment are surprisingly
increasing. To prevent such trouble, it is not
enough to depend entirely upon chemical or
equipment. Check the water quality and also
on environment factors as well.
1. Make quality analysis of circulating
water and supplementing water and take
appropriate action to control the quality.
2. If when the trouble is anticipated owing
to the condensed circulation water, we
recommended the use of chemical,
periodic below sown to keep the operation
within the regulate water quality.
3. For nitrate and sediment, clean with
chemicals.
4. Use strainer or filter depending on the
water quality.
WARNING
Water treatment must be supplied and /
or applied by a professional in the field in
order to avoid fill damage. It is the user s
/ owner s responsibility to treat water
in order to stop biological contaminants
and avoid among other bacterium, the
Legionella bacteria, which is known to
cause legionnaire disease.
20. Post assembly Checks/Precommissioning Checks
1. Check level of sump, and fan ensure they
are parallel to ground.
2. Check center pipe is vertical and
sprinkler arms are all leveled, at right
angles to center pipe.
3. Ensure no dirt/other foreign particles are
present in sump, suction tank etc. sweep
clean/wash clean.
4. Rotate sprinkler with hand and ensure it
is free.
5. Ensure fill top is even.
6. Ensure sprinkler arms are at a constant
level above the fills and that the arms do
not rub against/ uneven fills, casing etc.
7. Ensure fan and motor assembly is free.
8. Check all bolts are tight and no loose part
noticed.
9. Fill water in sump and check and
eliminate water leaks.
10. Connect correct power (i.e. 380V, 50Hz
3PH.AC) supply to fan and check
a. Direction of rotation of fan is correct
and air is being sucked through screen
above sump and discharged vertically
upwards.
b. Vibrations are negligible.
c. Fan cable connections are made with
lugs & terminal cover gasket is tight.
11. Establish water flow and check sprinkler
rotates and check any unregulated
bypass from sprinkler pipes.
Check after commissioning
1. Check motor speed to be as specified in
technical data for particular model.
2. Check air flow rate is as per specification.
3. Check water flow rate is as per
specification.
4. Check power / current drawn by fan
motor are within limits and as specified.
5. Check for abnormal noise / vibration
during operation.
6. Check sprinkler rotates freely at 5 to
8 rpm or adjust holes to angle so as to
achieve correct rpm.
7. Ensure water is being distributed evenly
over the FRP eliminator plates and there
is no carry over from below the eliminator
plate water must fall down below evenly
and not pass out.
8. Eliminator plate adjustment to be
checked to ensure equal distance
between fill top and plat bottom.
9. Measure temperature at following
locations:
I. Water inlet
II. Water outlet / sump
III. Make up water inlet
IV. Wet bulb / dry bulb temperature at outlet
59
of tower above fan
10. Adjust drain valve to give adequate blow
down.
11. Set float to ensure proper operation and
to avoid over flow when plant stops.

FRP Cubic Cooling Tower
Principals of FRP Cubic Cooling Tower
operation "Tahvieh Azar Nasim" Fiberglass
Cooling towers are inspired from the wellknown "Sulzer" cooling tower design, and are
designed and manufactured considering local
Iranian facilities and requirements. The most
important change in this design is considering
service hatches which unfortunately are not
considered in original design.
Casing
Different parts of fiberglass body would be
connected to each other by galvanized bolts
and nuts and make the strong integrated body
of the tower. The tower body can bear the
wind pressure up to 21 m/s. and it thwart the
vibrations caused by electro motor and fan.
Basin
The integrated rigid and reinforced basin is
designed so that the amount of water reserves
in basin should be as when the pump starts ,
air does not trap and when the pump is turn
off water does not overflow the basin.
Fan Deck and Fan Stack
The integrated rigid fan deck and fan stack,
reinforced by fiberglass is designed to assist
the air flow path.
The fans are dynamically balanced for
smooth operation, longer bearing life
including that of the supporting structure.
FRP fan blades may also be provided on
demand and these have in addition to
excellent corrosion-resistance, good noise
reduction properties.
Electromotor
Single speed electromotor, Standard TEFC
with IP55, F class are used in "Tahvieh Azar
Nasim" cooling towers.
Water Distribution system
Large orifice polymeric nozzles (Nonclogging) are one of the significant benefits
of cubic towers comparing the sprinklers of
FRP conical type cooling towers.
Drift Eliminator
PVC drift eliminator with three changes in
air path gives us less than 0.002% drift loss.
Considering the conditions of the area
(height from the sea level) there is
the option of changing the capacity of
electromotor.
Fills
Fiberglass cubic cooling towers suit two
types of fills, film type and splash type.
Cooling tower fills are designed to have the
maximum contact of air with the water and
cause the minimum pressure downfall.
Fan
The light weight fan has good corrosionresistant quality is an axial flow, multi blade
version with adjustable blade pitch. The fan
is designed to deliver large volumes of air
at low power consumption and low noise
generation.

FRP Closed Circuit Cooling Towers
Principals of operation
FRP Closed Circuit Cooling Towers act
quite like open circuit cooling towers, the
only deference is that in FRP Closed Circuit
Cooling Towers the fluid to be cooled (usually
water) flows through the tubes of the coil
without coming into direct contact with
external air, preventing dirt or pollution
entering the primary water circuit.
The heat is transmitted from the fluid
through the tube walls to the water, which is
being continuously sprayed over the coil.
The fan situated at the top of the tower
intakes air in counter flow to water, thereby
evaporating a small part of the re-circulating
water, drawing off the necessary heat
for evaporation and releasing it into the
atmosphere.
The rest of water is re-circulated with a spray
water pump from the basin to the spray
nozzles. (Secondary Circuit).
A small quantity of heat is transmitted by
convention to the external air, just as for an
air cooler.
In closed circuit cooling towers there are two
separated circuits.
1. Initial circuit which process fluid is
circulating
2. Secondary circuit which sprays the water
on the coil.
Fan
The light weight fan has good corrosionresistant quality is an axial flow, multi blade
version with
adjustable blade pitch. The fan is designed to
deliver large volumes of air at low power
consumption and low noise generation.
Driving system
Movement transfer from the electromotor to
fan would be delivered through a series of
belt, pulley and fly wheel. (Belt Drive)

INTRODUCTION
BENEFITS AND FEATURES
AzarNasim packaged air conditioning units are
compact systems intended for applications in new or
existing stores, restaurants, offices, schools, computer
rooms, airports, and industrial plants.
Available in cooling capacities from 5 to 80 tons in a
single unit, these units provide significant installation
versatility and economy in that they can be used to
supply the total cooling requirements in a variety of
commercial, institutional, and industrial applications.
Units can be selected with air or water-cooled
condensers in rooftop, indoor, and in case f aircooled
versions in split or packaged arrangements.
Furthermore, the units can be used for free delivery or
ducted applications. For ease of installation, the units
can be in vertical or horizontal configuration.
AzarNasim packaged units can provide year round air
conditioning with hot water, steam or electric heating
coil during the cold season. They can also be used to
supplement central systems, permitting zone control
at low load conditions without the expense of central
systems.
Each unit is factory assembled, wired and shipped
as a package. This greatly reduces installation
time and assures the optimum positioning of the
components.
In the areas where water supply is either unavailable
or scarce, the air cooled units can be used. The
aircooled split unit requires only the addition of the
remotely located AzarNasim Air Cooled Condenser for
complete air conditioning.
All components in AzarNasim packaged units are
designed for maximum performance and reliability.
74
The basic component of the AzarNasim packaged
unit is a semi-hermetic type multi-cylinder compressor designed to run on 380 volt, 3 phase, 50
cycle power input. Motor protection on these units
is comprised of three sensors mounted internally in
the motor windings which in case of charges in motor
temperature shuts off the compressor. An oil safety
switch provides protection against loss of oil pressure.
All controls and factory wiring are protected within
galvanized steel enclosures.
The DX cooling coil is designed and rated accord-ing
to ARI-410 Standard. To maximize perfor- mance, a
venturi flow distributor assures even distribution of
flow into the cooling coil tubes. Suction line piping
is insulated with closed cell insulation to prevent
moisture condensation. The DX coil section is
insulated with 19mm rock wool panel with aluminum
foil cover.
The water cooled condenser is a shell and tube type
heat exchanger, sized sufficiently to hold the total
refrigerant charge on pump down operations. An
integrated sub-cooling section allows system capacity
increase without an increase in power.
The condenser shell design meets the ASME- Section
VIII, DiV.1, Boiler & Pressure Vessel Code
requirements in addition to TEMA Standards.
The air-cooled condenser is configured so that air
discharge is directed upward thus carrying heat away
from the unit and minimizing directional sound. The
fan is statically and dynamically balanced therefore
assuring smooth and quiet operation.
For industrial process cooling and year round air
conditioning, custom built units can also be designed
and constructed.

LDB = 80 °F -
SHC
1.087 xCFM
539300
= 59.3 °F
1.087 x24000
The Leaving Wet Bulb temperature can be
calculated according to the following method:
H2 = H1 - TC x 1000
4.5 x CFM
= 31.62 - 735.9 x 1000 = 24.9 BTU/Ib
4.5 x 24000
From TABEL 64, at 0 altitude interpolate between
24.48 and 25.12 BTU/lb to read
LWB = 57.7 °F
D. From the Heating Coil Ratings in TABLE 45,
for Model Anpu-70-A-2,a 1 row heating coil (Full
Circuit-8 FPI) with the following specifications can
be selected:
Heating Capacity = 1,001,800 BTU/hr
Air Flow Rate = 28000 CFM
A. Consider Model Anpu-70-A-2 from TABLE 38,
Interpolating between 23040 and 25920 CFM at 67
°F EWB, results in the following quantities:
Total Cooling Capacity (TC) = 725.9 MBH
Sensible Heat Capacity (SHC) = 539.3 MBH
Compressor Power Consumption = 62.6 KW
B. To determine the Total Heat Rejection, THR,
enter TABLE 38 with CT = 125 °F and interpolate
between 23040 and 25920 CFM. The THR is then
found to be:
THR = 939.6 MBH
Next, to select an air cooled condenser, refer to
the Total Heat Rejection Chart in the AzarNasim
Air Cooled Condenser Catalog with:
TD = 125 - 90 = 35 °F
Model Anpu-550-R can be selected to appropriately
reject the total heat.
76
Since the CFM listed in the table is not equal to the
design CFM, a correction factor must be applied.
CFM
= 24000 = 85.7 %
NOMINAL CFM 28000
From TABLE 42, interpolating between 80%
and 90%, a correction factor of 0.92 is obtained.
Next, a hot water coil correction factor must be
determined.
Enter Figure 1 at 50 °F EDB and moving vertically
upward to 160 °F EHT, the correction factor can be
found to be 0.93 The actual heating capacity is then:
Actual Heating Capacity =
1,001, 800 x 0.92 x 0.93 = 857,200 BTU/hr
E. From TABLE 43, for a 1 row coil, the internal
static pressure is found by interpolation to be
0.07" w.g. Similarily for a 4-row cooling coil, the
static pressure drop is found to be 0.4" w.g. The
SELECTION PROCEDURE
total system pressure drop is:
∆ P Total = ∆ P internal + ∆ P external
C. From TABLE 7, the condenser pressure drop is
PD = 16.2 ft. water
= (0.07" + 0.4") + 0.5" = 0.97" w.g.
D. The Leaving Dry Bulb temperature is calculated
according to the following relation:
From the Fan Performance Chart on TABLE 49, for
Model AnpuA-70-2 with a static pressure of 0.97"
w.g., 24000 CFM, and interpolating between 0.75"
and 1" static pressure the following quantities can be

A. Consider Model AnpuW-15-1 from TABLE 7 ,
interpolating between 5400 and 6000 CFM at 72 °F EWB,
Permits the determination of the following quantities:
Total Capacity (TC) = 207.6 MBH
Sensible Heat Capacity (SHC) = 105.7 MBH
Compressor Power Consumption = 10.2 KW
B. From TABLE 7, the condenser water flow rate is:
GPM = 45.1
H2 = H1 - TC x 1000
4.5 x CFM
= 35.83 - 207.6 x 1000 = 27.4 BTU/Ib
4.5 x 5500
From TABLE 64, interpolating between 27.85 and
28.57 BTU/lb result in LWB = 61.4 °F.
E. The Heating Coil Capacity for Model AnpuW-15-1
configured with a 2-row coil (Full Circuit-8 FPI) and
EDB = 60 °F , from TABLE 45, is:
Heating Capacity = 338.7 MBH
Next, the hot water coil correction factor of 0.85
can be read from Figure 1 at the intersection of
a vertically projected line from 60 °F entering
air temperature up to the 160 °F entering water
temperature line and projection horizontally to the
left to correction factor axis.
Since the CFM in the table is not equal to the design
CFM, a correction factor must be applied.
CFM
= 5500 = 91.7 %
NOMINAL CFM 6000
Interpolating between 90% and 100% in TABLE 42,
a correction factor 0.96 is obtained. Applying the
hot water and CFM correction factors to obtain the
actual heating capacity as:
Actual Heating Capacity = 338700 x 0.85 x 0.96
= 276.4 MBH
F. The total static pressure, fan speed, and horse
power are calculated similar to the procedure
outlined in part e) of EXAMPLE 1 as:
∆ P Total = 1.1" w.g.
RPM = 780
HP = 3

SELECTION PROCEDURE
EXAMPLE 4: Non Standard Condition
Water Cooled Model
Notes:
Air cooled condensers must operate under different
ambient conditions is order to provide sufficient heat
rejection from the air conditioning cycle. All manufacturers therefore publish condenser ratings under
a standard condition. For any condition other than
the standard condition stated by the manufacturer,
correction factors must be applied to the total heat
rejection in the packaged rating tables. One such
correction factor is altitude correction factor given in
the table below which must be applied to the total heat
rejected from the air cooled packaged unit in order to
select the appropriate air cooled condenser.
Given:

Total Cooling Load (TC).................................260 MBH
Sensible Heat Capacity (SHC).......................140 MBH

Select Anpu-20-W-1 from TABLE 8, with TC=240.8
MBH and SHC=186 MBH at 80 °F EDB. The face
velocity, FV, is calculated according to the following
relation:

EXAMPLE 3: Altitude Correction Factor
Suppose the air cooled condenser of EXAMPLE 1
is to operate under the same summer and winter
condition except at the location stated below:
Geographic Location: Tehran
Altitude: 1190 meters
The unit selection and the calculation of the Total
Heat Rejection (THR) is identical to the steps a) and
B) in EXAMPLE 1. Hence:
FV = CFM = 8800 = 550 FPM
FA
16.0
Where the face area, FA, for packaged units
is listed in TABLE 1. With the calculated face
velocity enter TABLE 40, under the 4-row coil the
Bypass Factor, BF, is given as 0.26. Next, enter
TABLE 41, at 83 °F EDB and interpolate between
0.25 and 0.30 BF. The CF is then calculated as
2.42. The corrected TC and SHC for EDB=83 °F
can be determined according to:
TC = 240800 + 8800 x 2.42 = 262000 BTUH
SHC = 186000 + 8800 x 2.42 = 207000 BTUH
Since the calculated TC and SHC can atisfactorily
meet the given load, the leaving dry bulb
temperature can be calculated as:
LDB = 83 °F -
Model Anpu-70-A-2
THR = 939.6 MBH
207000 = 61.4 °F
1.087 x8800
It can thus be seen that the design leaving dry bulb
temperature of 66 °F can be attained.
From TABLE 3, the Correction Factor CF = 1.0902
by interpolation. Applying CF to the Total Heat
Rejection leads to the new value for THR:
The leaving Wet Bulb temperature can be
calculated according to the following method:
THRNew = THR x 1.0902 = 939.6 X 1.0902 = 1024 MBH
H2 = H1 -
From AzarNasim Air Cooled Condenser Catalog for
TD = 35 °F and THR New = 1024 MBH, air cooled
condenser Model Anpu-700-R can be selected.
From TABLE 64 at 0 altitude interpolate between
29.31 and 28.57 BTU/lb to read LWB =63.8 °F.

1. For ducted applications of AzarNasim Packaged Units with electric heating coils, an automatic air flow switch will
be supplied separately. Before starting up the unit, the air flow switch must be installed in the duct and wired to the
electrical control panel as per electrical wiring diagram instructions. Failure to do so will cause damage to the electric
heating elements and void the guarantee.
2. Before switching unit to winter season application, system pump down must be performed.

Note:
1. Compressor circuit breakers are current sensitive and temperature compensated to ensure compressor cutoff if current
draw becomes excessive. Breakers must be resent manually.
2. Internal protection with automatic reset de-energizes the control circuit if extreme compressor motor temperature
should occur from excessive return gas temperature or motor overloading.
3. High and low pressure controls automatically shut off compressor(s) if refrigerant pressure exceeds switch settings.
This action protects against loss of charge.
4. All compressors are 380/420 volts 3 phase 50 cycles.

1. Compressor circuit breakers are current sensitive and temperature compensated to ensure compressor cutoff
if current draw becomes excessive. Breakers must be reset manually.
2. Internal protection with automatic reset de-energizes the control circuit if extreme compressor motor
temperature should occur from excessive return gas temperature or motor overloading.
3. High and low pressure controls, automatically shut off compressor(s) if refrigerant pressure exceed switch
settings. This action protects compressor against loss of charge or damaged caused by excessive pressures.
4. All data are based on 125 °F condensing, 45 °F evaporating & 95 °F ambient air temperature.
5. 5- All compressors are 380/420 Volts-3 phase-50 cycles.

Minimum calculated pressure differential (psi) across the valve
to fully lift the disc.
Remote Air Cooled Condenser Notes:
1. Refrigerant piping design must accommodate the flow of both refrigerant and oil. Proper return of oil to the crankcase is
accomplished by ensuring a minimum refrigerant velocity not less than 500 fpm in horizontal lines and not less than 1500
fpm in vertical refrigerant risers. Horizontal refrigerant lines must be pitched in the direction of refrigerant flow.
2. Copper tubing installed in remote air cooled condenser systems should be entirely free of dirt, scale, and oxides. The
liquid line from the condenser should be maintained dry.
3. Current practice limits the maximum pressure drop in liquid lines corresponding to a change of saturated temperature
ΔTsuc = 1 °F as 3.05 psi at a condensing temperature of 105 °F.

WATER COOLED CONDENSER PIPING DETAIL
The above diagram is intended as a
general guideline for connection points
and equipment arrangement for water
cooled condenser applications and is not a
proposed detail for a specific installation.
All piping and duct work must follow
standard techniques and all wiring must
comply with applicable codes.

Note:
1. when vertical lift exceeds 7.5
meters, install oil traps at every 6
meters.
2. Discharge check valves must be
installed on remote air-cooled
condenser applications to prevent
refrigerant migration during off
cycle.
3. "Over Traps" on top of risers must
not be less than 150 mm.
4. Oil separators are mandatory on
systems where distance between
packaged unit and remote aircooled
condenser exceeds 20 meters.

AIR HANDLING UNIT
Features
In all Azar Nasim air handling units the
frames are made from aluminum profiles
while the chassis and body panels are made
from galvanized steel sheets in appropriate
thicknesses. Azar Nasim air handling units are
manufactured in some features of which are
offered below. All units are completely painted in
the proper thickness.
1. Fan section:
In this section double width-double inlet
centrifugal fans with forward curved blades
are normally used for low pressure downfall
requirements as opposed to fans with
backward curved blades which are for high
pressure downfall applications. Fans and
housings are made of galvanized steel each
set offaplus other related components such
as shafts are statically and dynamically
balanced, shafts are selected from proper
material and size.Other power transmission
components such as pulleys and belts
are also suitably chosen depending on
the required fan speed and electric motor
power. Fan(s) and the corresponding electric
motor(s) are installed on an independent
chassis which is itself installed on the main
chassis using vibration dampers in order
to eliminate transfer of vibrations to the
structure. To further reduction the effects of
vibrations, fan outlet (s) are also connected
to the structure via flexible material such
as canvas. Where an air washer section
is included, the blower electric motor is
installed outside of this section to prevent
adverse effects of moisture. In other cases,
blower electric motor is installed in the fan
section. All 380V/30/50hz electricmotors
are selected with insulation class of (f) and
130
ingress protection of (ip -54). Electricmotors
with ingress protection of (ip-55) are also
available upon request.
2. Coil section:
This section may include cooling and heating
coils or either one of the two depending on
the Requirement.
Cooling coils are available in two types of
chilled water and direct expansion (D.X.) As
per client s requirements. The chilled water
coils are constructed of 5/8 O.D copper tubes
plate finned (8, 10, 12 or 14 fpi) in aluminum
or copper upon request. The DX Coils are
constructed of 3/8 OD copper tubes also
plate finned (10, 12 or 14 fpi) in aluminum
or copper as required. The chilled water for
cooling coils is to be supplied by a water
chiller and in the D.X. coils cooling is provided
through the use of refrigerant such as R-22,
R- 407c or R-134a.
Chilled water coils may be requested in 4,
6 & 8 rows and as to the D.X. coils; they are
available in 4 or 6 rows configurations.
Heating coils are available in two types of
hot water and steam. The hot water coil just
like chilled water coil is offered in 1, 2, 3 &
4-row configurations. Steam heating coils
are constructed of 1/2 seamless steel pipe
spiral finned in aluminum or copper. Coils in
1&2 -row configurations are available upon
request.
3. Mixing box section:
This section is where the fresh and return
air streams are mixed. An independent air
damper is included for each air stream.
Dampers are manufactured from aluminum
in opposed blade configuration and air sealed
through the use of rubber strip gasket.
Damper actuators maybe easily installed
when required. 2 inches Washable aluminum
filter modules are arranged in (V) type
configuration inside these boxes. Housing
for pleated type air filters may also be
considered in the mixing box.
4. Special filter section:
This section may include pleated or bag
filter which are installed as per customer
requirements. Efficiency and class of special
filters are specified by the client.
Notes:
• Allowable air velocity must be over the
special filter section.
• In cases where only pleated filters are
required they are easily installed in
themixing box and not in the special filter
section.
are installed one which is on the cooling coil
side and one that is on the heating coil side
active. When outlet damper is open, the other
one is close. The same amount, therefore, by
adjusting the outlet dampers for each zone,
the desired zone temperature is controlled.
Number and the effective area of dampers
for each zone are dependent on the number
of zones and the air flow rate needed for that
zone. These aluminum dampers are located
either on top or the blank side of this section
depending on the type of air handling unit is
up blast or horizont al blast discharge. Multizone section is usually installed after the
fan section and in order to have the proper
air flow over the coils air diffuser is also
installed. Humidifiers are also installed in
this section when required.
5. Multi - Zone Section:
In some cases the air conditioning design
of a building defines different zones to be
air conditioned, each zone requiring its own
air flow rate and air temperature. In these
cases instead of using a few air handling
units, a multi -zone unit is usually installed.
Inthemulti-zone air handling unit, cooling
and the heating coils are paralleled with
each other which means that some of the
air passes over the cooling coil and the
remainder passes over the heating coil and
at the outlet the result is a mixture of the
two which has the suitable temperature for
each zone. Inmulti-zone units the cooling coil
area is the same size as that of a regular air
handling unit while the size of the heating
coil is less. For each zone two outlet dampers
131
Selection procedure
The first parameter to consider in the selection of an
air handling unit is the required air flow rate (CFM)
therefore,by having the required air flow rate, coil
face area and the available nominal air flow rate for
the unit, the appropriate model may be chosen.
Notes:
Allowable air velocity over cooling coils is less
than 550FPM.In air handling units equipped with
air Washers this allowable airvelocity shall be
reduced further to less than 500 FPM.
Considering the cooling and heating loads and
the entering air conditions. The number of coil
rows, pressure drops on both water and air sides
and the required model of fan may be determined
using the data available in the catalogue. Other
components and accessories such as air mixing
box, special filters, humidifier, etc. May also be
selected from the ccatalogue as needed.

•
Knowing the actual coil velocity and the coils
chosen, determine the total internal air side
pressure downfall for the unit. From the table
P.D. Cooling coil = P. D. (Table 17) x C.F. (T able
10A) = 0.85 * 1.45 = 1.19 In W.G
P.D. Heating coil = P. D. (Table 17) x C.F.
(Table10A) = 0.22 * 1.45 = 0.32 In W.G
P.D. Filter = 0.099 In W.G
P.D. Accessories= 0.05 + 0.06 = 0.11 In W.G
(damper & mixing box from table 18).
Total internal pressure drop (T. I.P .D)
Tot al external pressure drop (T.E.P .D)
T.I.P .D = P.D. Cooling coil + P.D. Heating c o i l +
P.D. Filter + P.D. aaccessories
T.I.P .D = 1.19 + 0.32 + 0.099 + 0.11 = 1.719 In W.G
Total static pressure (T.S.P)= T.I.P .D + T.E.P .D =
1.719 + 0.78 = 2.5 In W.G
Therefore, by using table 1 and performing
interpolation the required fan size is determined
as 22” at the speed of 703 RPM and electric
motor power requi rement of 10 HP.

From Table 21 considering the 2 row heating coil,
the water velocity of 3.2 Ft /Sec, the pressure
drop is given 2.62 Ft w.g and a.The average water
temp, of 170 F correction factor is0.77 theref ore,
the actual P.D. is 2.02 Ft W.G.
Knowing the actual coil face velocity and the
coils chosen, determine the total internal air
side pressure drop for the unit.
P.D. DX coil = P.D. (Table 17) x C.F. (Table 17A) =>

Air Washer Selection Procedure
Given: Entering air DB temperature = 95 ˚F
Entering air WB temperature = 63 ˚F
Sensible cooling load = 85 MBH
Design air flow rate = 10000 CFM
Room DB temperature = 77 ˚F
Determine the required air washer model,
Q = 1.085 × CFM × (D.B Room, - D.B Lvg.)
D.B Lvg. = D.B Room =77-
85000
= 69.16 F
1.085x1000
Considering the required air flow rate in CFM
& the unit available nominal air flow rate, air
handling unit Model AHU 1000 is chosen.
Evaporative cooling efficiency (E) is determined as,
E = D.B. Ent - D.B. Lvg = 95 - 69.16 = 0.8
D.B. Ent - W.B. Ent 95-63
The coil face area for model 1000 is 20ft² therefore.
F.V = 10000 = 500 FPM
20
Considering the air velocity & the values in
table (A) the (E) value for Class 4 air washer is
equal to 0.555 Which is less than the calculated
value therefore Class 4 air washer dose not
fulfill the requirement. In This case since the
(E) value is known, the (P.F) value from table
(B) is determined as being equal to 0.75 Now,
considering the unit model AHU 1000, the (P.F)
value & table (C) the (P.F) value for Class 6 air
Washer is less than the value calculated
therefore; Class 8 washer fulfills therequirement.
We also notice that the (P.F) value given is 0.821,
the actual (E) value is 0.856 (Table B) the Lvg. Air
DB temperature is given as.
DB Lvg = DB Ent E × (D.B Ent WB Ent) = 95
0.821 × (95 – 63) = 68.7 ˚F
Therefore, the actual air washer cooling capacity
is given as.
Q = 1.085 × CFM × (D.B Room DB Lvg) = 1.085 ×
10000 × (77 68.7) = 90055 BTU/hr. ~ 90 MBH
Entering the metric chart with the leaving air
DB & WB temperatures of 68.7 ˚F & 63 ˚F
Respectively, the relative humidity of the air is
determined to be 73%.

Condencer
Features
General
Azar Nasim Air cooled Condensers are offered
in 12 models with refrigeration capacity range of
18.6 to 2017 MBH, designed to accommodate a
wide range of applications in the A/C industry.
Casing
Proper thickness galvanized steel sheets are
used in the structure of casing panels and
mounting legs formed from heavy steel sheets
which are joined by bolts offer maximum rigidity
and facilitate repairing.
Coils
Condenser coils consist of seamless cooper
tubes mechanically expanded into die formed
aluminum or copper fins with 10, 12, 14 FPI
spacing. Coils are available in single and multicircuits.
Fans
Directly driven axial fans, deliver the required air
flow rate at minimum sound levels. All fans are
equipped with fan guard for maximum protection.
Fan operation sequencing is performed based
on the liquid refrigerant’s pressure leaving the
condenser.
Motors
Totally enclosed air cooled (air over body) electric
motors equipped with permanently lubricated
bearings, an IP-55 protection, winding insulation
class of (F) plus thermal protection and B rise
construction are mounted in vertical position. The
motors are suitable for operation.
Electrical Panel
Consists of a drip proof panel enclosing all
electric components such as contactors, over
load protections and
Testing
Condenser coils have passed the leakage test 450
psig after production and the entire condenser
unit has tested at 350 psig working pressure after
completion.

Selection Procedure
Helpful Hints
Maximum allowable condensing temperature for
R-22 & R 407 C : 135 ˚F
Optimum condensing temperature for R-22 & R
407 C : 120 ˚F
TD: Condensing temperature Ambient dry bulb
temperature.
THR = [System cooling capacity] + [Compressor
motor power input x 3413].
When compressor motor power in the formula
above is not known use values from table 8 in the
following relationship:
THR = [System cooling capacity] x [Heat of
compression factor]
Example 1
Given:
System cooling capacity: 210000 BTU/Hr.
Condensing temperature: 120 ˚F
Ambient air temperature: 100 ˚F
Compressor power input: 18.2 Kw
Design altitude: 2000 Ft
Coil fin per inch: 14 FPI
Fin material: Aluminum
Example 2
Given:
System Total Heat Rejection ( THR ): 350000 BTU/Hr.
Condensing temperature: 120 ˚F
Ambient air temperature: 100 ˚F
Altitude: 4000 Ft
Coil fin per inch: 10 FPI
Fin material: Copper
Refrigerant: R 22
Select matching air cooled condenser
Determine Total Refrigeration:
THR = 210000 + (18.2 x 3413) = 272117 BTU/Hr.
From Table 2 for altitude adjustment factor (@
2000 Ft) AF = 1.05
Adjusted THR = (1.05) (272117) = 285723 BTU/Hr.
TD ( Design temperature difference ) = ( 120 100)
=20 ˚F
From table (4) and TD of 20 ˚F. ANC 250 with
plate fins offers 273000 BTY/Hr. which fulfills the
above required THR.
Select matching air cooled condenser
TD: Cond Temp - Ambient Temp = 120-100 = 20 ˚F
Total Heat Rejection Requirement = THR x
Correction Factor (Table 10) / Correction Factor
(Table 9) = 350000 x 1.10/085 = 452941 BTU/Hr.
= 452.941 MBH from Table (10) and T.D of 20 ˚F,
ANC-450 offers.

ZENT
Introduction
"Zent" is an air conditioning device which can
provide the relatively summer conditioned air
by passing fresh air through wet chaff pads.
In winter a combination of returned indoor air
and fresh air, after Passing through a washable
aluminum filter, first would be cleaned and then
pass over a hot water Heating Coil (or electric
or steam coil) and warms. In winter conditioned
warm air humidity may Increase by different
alternatives.
Zent Room
"Zent" would place in a covered area where could
be called "Zent Room". The most appropriate
Place for the "zent Room" is the center of the
building that provides the possibility of entrance
of the Fresh air through a window and entrance
of the returned air through a damper, to "zent
Room".
"Zent Room" ought to contain enough space for
supply channels and its floor has to be isolated
against water And have drainage, and its better
that the walls are acoustic.
"Azar Nasim Zents" Advantages:
1. Variety
Vertical and horizontal models are produced,
occupy minimum space.
2. Fan Controller
Usage of speed control, decrease the electric
consumption cost and uniform working of
unit.
3. Elimination of radiators and pipe lines
Decorativeness, save space , decrease repair
costs.
178
4. Adjustable Dampers
Changing the summer system to the winter
system and vise versa in the simplest way and
the possibility Of humidifying the winters hot
air.
5. Washable Aluminum Filters
Clean air; increase the efficiency of heating
Coil and long lasting unit.
6. Coil is placed inside "Zent"
Less heating loss, more safety
7. Basin Fiberglass Cover
Long lasting life and elimination of bacteria.
8. Very easy Service
No needs of professional repairman
9. Fan

CFM these units can meet the air conditioning
demands of a variety of multi room applications
such as apartments, office buildings, hotels and
hospitals. For cooling applications, units are
Available with capacities ranging from 20 to 100 K
Btu/hr. and for heating units with capacities of 60
to 200 K Btu/hr. at standard conditions (80°F DB,
67°F WB) can be utilized . With 3 different models
and seven basic, sizes in each model along with
the choice of Vertical or horizontal types. The
wide selection range offers considerable design
versatility.
CABINET
All cabinets are constructed of 1.25 mm
galvanized steel sheet with additional paint
coating. Panels are insulated with 10 mm
polyethylene insulation panel.
EASE OF INSTALLATION & MAINTENANCE
Horizontal models can be used in cabinet
(Exposed) or furred-in (Concealed) applications.
Vertical models are built only in exposed free
standing models. The low high dimension
associated with the horizontal types facilitates
easy installation within double ceilings or
concealed locations.
COILS
Coils are constructed of 5/8 inch O.D. copper
tubes with waffled and rippled edge aluminum or
copper fins mechanically bonded to the tubes. All
coils are leak tested under water with 325 Psig
air in accordance with ANSI/ASHRAE 15 Safety
Code for Mechanical Refrigeration.
Supply air duct collar simplifies field connection
to new or existing supply ductwork. Mounting
Brackets on each side of the unit allow swift
suspension from the ceiling. All wiring and piping
connections are located at accessible locations
on the unit. Removable bottom panels permit full
width access to the mixing box and blower units.
Motor-blower unit can be removed in order to
expose the entering face of the coil for cleaning
purposes. The following design features are
incorporated in the construction of AZAR NASIM
ducted Fan-coil units.

FILTERS
Standard filter is removable 1" aluminum mesh
washable filter.
CONDENSATE DRAIN PAN
Condensate drain pan is constructed of heavy
gauge galvanized sheet metal with the underside
Insulated by 3 mm Polyethylene foam. The
condensate drain outlet is 3/4 inch O.D. copper
tube, Brazed into the condensate drain pan.
The coils for hot water applications are identical
to chilled water coils available in 4 or 6 rows. All
DX coils are evacuated and backfilled with 5 Psig
dry nitrogen prior to shipment. Electrical coils
could also be mounted on any unit. They shall be
protected against overheating.
FANS
The fans are direct driven, centrifugal, forward
curved, double width wheels. (DWDI) Fans of The
units have three speeds level adjusting: Low,
Medium and High.
MOTORS
Motors are three speeds, 4 poles, single
phase-50 cycles- 220 V with external rotor-motor.
All motors are equipped with thermal overload
protection. Motors are split phase type with a
capacitor. They possess four connection wires:
one in common and three connection wires for
three different speeds. If there is a need for more
than three different speeds, an autotransformer
can be used. (Transformer or any other device
should make no change in the shape of the
electrical sinus wave.) The following wiring
diagram can be used.

CONTROL FEATURES
There are different ways of controlling fan coils:
1. Fan Speed Control a) Manual >
The units are provided with a manual three- fan
speed control. (Unit or wall mounted)
2. Water Control Valves a) Manual >
By having hand-operated valves installed in the
supply or return water circuit, each unit could
be isolated from the whole water system. (Not
included)
B - Automatic
The fans could be switched ON/OFF while has
been set to one of the three different working
condition (Low, Medium or High) by a singlestage thermostat. (Not included) A Four-stage
thermostat (including OFF) could also control
the fan speed automatically. (Not included)
206
B - Automatic
Valves could be either solenoid or motor operated.
Two or Three way valves also could be used.
(Not included) Thermostat could control a
solenoid valve or also two-way or Three-way
water Valve to set the suitable flow rate of water.
(Not included)
3. Electrical Coil Safety Temperature Control
An optional control device could turn off the
electrical coil if its temperature rises above a
defined limit.(Not included)

UNIT HEATER
INTRODUCTION
This catalogue consists comprehensive
information of unit heaters manufactured by
Tahvieh Azar Nasim Company. Unit heaters of this
company are designed for provision of warm air
for industries, sport salons, store houses, pools
and other similar places and heating fluid of these
unit heaters is pumped hot water or water steam
system. This system is usually installed above
the ground level and air outlet is in horizontal or
vertical position.
Main elements details:
Main structure of each unit heater consists of
aluminum or steel body or fiberglass decorative
body, heating coil made of copper or steel
pipes and aluminum fins, air outlet damper has
adjustable single blades and propeller fan and
electromotor, axial fan and related guard, four
hanging plates according air outlet position
(horizontal or vertical) for installation of unit
heaters at the place.
Body:
The body is made of steel sheet with appropriate
thickness together with one layer of baked furnace
color; body of the decorative is made of fiberglass
and aluminum body with aluminum sheets without
color in different sizes and dimensions.
Coils:
Water coils are made of copper pipes and water
steam coils are made of seamless steel pipes.
Standard fins of both coils are made of aluminum fins.
Copper fins may be made upon request. Electrical coil
may replace water or steam coils as well.
Fan electromotor:
Electromotor of unit heaters are single velocity.
ordinary electro motors are supplied with low
velocity or any velocity according to order of he
customer. Single phase and three phase motors
both may be supplied upon request of the
customer.
(for industrial, hothouse units centrifugal fans are
used with static and dynamic balance.)
214
Fireproof electro motors (anti friction)
For dangerous places, elector motors with Exd
certificate , Zonel, A11, B11 and heat temperature
of class T4 is supplied. Velocity of existing electro
motors is 1400 RPM which are wire wrapped as
single phase or three phases.
Air damper:
Dampers are manually adjustable in which every
blade is regulated singly and installed in outlet of
unit heater. For hothouse unit heaters no damper
is installed and standing industrial units dampers
are according to Italian ARISIO brand.
Classification of unit heaters:
1. General Industrial Unit Heaters
2. Standing Industrial Unit Heater
3. Hot house Unit Heaters (special for high
temperatures above 60 centigrade)
All the three types may be designed and produced
using hot water, steam, hot oil coils and electrical coils.
<Note: for this special case antistatic blade
fans are supplied.

PIPING
As the function of a unit heater is to transfer heat from steam
or hot water to the surrounding Area. It´s necessary that the
steam or hot water be delivered to the unit and removed from
it In required quantity and condition.
The piping of the unit heaters must conform strictly to the
system requirements, while at the same intended. The
following are a few piping guidelines which must be observed
when Designing piping system for unit heaters.
1. Steam and condensate lines in steam unit, must be sized
for maximum load condition. This rule must be observed
in hot water units, too. The maximum pressure loss in hot
water Piping is 1m H2o per 30 m equal length of piping.
2. In steam unit heaters installation, the supply line should
be pitched towards the main line In order to prevent of
condensate flow into main line where it might reduce
capacity and Cause noise, in hot water unit heaters both
supply and return lines should be paralleled towards the
unit.
3. The return line in steam unit heaters must be installed
at minimum 300 mm below the unit, This prevents
accumulation of condensate water in the return line,
check valve, strainers and Traps. It also increases life
time of this parts and will improve unit operation.
4. By using a steam trap in return line can improve heating
capacity certainly. The trap size Must be proportionate
to unit capacity, otherwise, the condensate water will
accumulate in The unit or steam will eject from return
line.
5. Dirt trap in return line, prevent entrance of dirt and scales
in to the pipe line. Furthermore, by cleaning the dirt trap
cartridge, you can throw away all scales and dirt from inside
the Pipe line.
6. By connecting an air vent (at least 3/4") on top of the return line,
can dearate piping system, periodically.
7. In order to improve the efficiency of system, it's necessary
to insulate all pipe lines witch Are in contact with cold air
in winter.
8. Steam piping and unit heaters should be supported
independently.

MODEL SELECTION:
Once determined the minimum volume of the air to be
circulated inside the environment and Select the minimum
number of units to install, the sizes and features of the
units that better Fulfill the installation necessities have to
be pointed out in the tables. Generally it's better to Select
the units working at normal ration speed.
MAIN TENANCE RULES:
Azar Nasim unit heaters are hydraulically and
mechanically tested. For this reason, along Working time is
guaranteed without defect. The operating and the duration
of the unit heaters Can be improved and extended following
a maintenance program as listed below.
FAN MOTOR ASSEMBLY:
In case of various interventions of the magnetic starter,
measure the current absorption (Amp) and be sure that
it's not greater than the ratings of motor. The bearings are
self Lubricated closed type and don t require particular
maintenance and lubrication. If they will Result particularly
noisy; please order to replacing them, at the beginning of
each working Period, control that the blade is clean and
without fouling on the both sides on the contrary Dismount
the blade and put into a degreasing solution.
HEATING COIL:
At the beginning of each working period, it is necessary
to clean the exchanging coil By means of blower with
compressed air or brushing. In case of grease presence,
Wash the finned pack with a degreasing solution and pay
attention to don t wet the motor and Affect a well done
drying of the exchanging coil before starting. The necessity
and Frequency of the cleaning depends on the dust inside
the environment where the unit heaters Are installed.
Generally the above maintenance is elected yearly before
each winter. During such maintenance, control the fixing
screws, in motor mounting, blade and brackets, Regarding
the spare parts of the unit and the ratings of the motor.
