The Carrier Corporation has more than 100 years experience
in providing HVAC systems and equipment around the world.
Sanyo is a leading manufacturer in the field of highefficiency absorption chillers. Carrier-Sanyo absorption
chillers, produced by Sanyo for Carrier, provide a unique
choice of models for all absorption chiller applications.
Features
■ The Carrier-Sanyo gas-fired double-effect absorption
chillers/heaters offer building owners a better solution for
many new and retrofit applications. Installation of a directfired chiller/heater eliminates the need for the boiler required
with conventional installations. This reduces the initial cost
of the system, making Carrier-Sanyo chillers/heaters
competitive with conventional chiller/boiler systems.
■ Excellent for peak shaving during high electrical demand
periods.
■ Units can provide cooling without expensive electrical
service upgrades.
■ Carrier-Sanyo gas-fired absorption chillers allow
diversification of critical cooling requirements. Critical
cooling loads are met with minimal electrical power input.
■ 16DJ units allow the use of for smaller emergency generators
since the electrical load associated with an absorption chiller
is minimal compared to an electrical driven chiller.
■ The units are ozone-safe and CFC-free. Cooling requirements are met without chlorine-based refrigerants.
■ They reduce the contribution to global warming and
minimize the global impact by greatly reducing electricity
consumption and eliminating production of greenhouse
gases.
■ The molybdate solution inhibitor has no impact on the
environment.
■ An absorption chiller does not utilize a large motorcompressor, and this leads to quiet, vibration-free operation.
■ The high-efficiency of double-effect chillers has reduced the
space required for installation of the absorption chiller,
resulting in a smaller footprint.
Carrier-Sanyo is the industry leader in compact absorption
units.
Carrier-Sanyo absorption chiller features
With the ever-changing requirements of building owners and
continual changes in building designs, Carrier-Sanyo
introduces the next generation of high-efficiency gas-fired,
double-effect absorption chillers to the world market.
In many parts of the world, the cost of electricity and
penalties administered through demand limits, inverted rates,
time-of-day rates, ratchet clauses, etc. have forced the need
for alternative chiller systems to be developed.
Electrical peak power shaving
■ By using a combination of electrically driven and absorption
chillers for air conditioning loads, a central plant can take
advantage of lower base electricity rates during times of high
electricity demand. The absorption unit is used to shave peak
power demands during summer operation, while operating
the electric chiller below the assigned demand limit, avoiding
costly demand charges and saving money all year-round.
■ With the limited capacity of the world power plants and
environmental and financial concerns blocking construction
of new ones, many areas are faced with extremely high
demand charges and escalating electricity costs. In these
areas, the entire cooling load can be handled by CarrierSanyo absorption units, allowing the allotted electricity to be
used elsewhere in the building where there are no practical
alternatives.
Heating and cooling operation
■ With the Carrier-Sanyo 16DJ direct-fired double-effect
chillers/heaters, the unit can be used for heating during
winter months without additional cost of extra controls. In
many applications the chillers/heaters can replace a
traditional electric chiller and boiler design combination,
with the advantage of reducing machine room floor space
and realising up to 40% savings on the system start up cost.

Double-effect absorption cycle
■ The direct-fired Carrier-Sanyo chillers utilize a double-effect
absorption cycle resulting in unit COPs of 1.1 for the directfired chillers/heaters. This high-efficiency design has reduced
the input energy of the original single-stage-absorption
chillers by up to 30 %. The Carrier-Sanyo state-of-the-art
double-effect design has also allowed the unit to be reduced
in size compared to previous generation units, making
Carrier-Sanyo the industry leader in efficiency and space
utilization.
Many applications
■ Carrier-Sanyo offers one of the widest equipment ranges and
operating conditions in the entire industry: 23 discrete unit
sizes from 350 kW to 5300 kW. Using natural gas as one of
the heat sources for direct-fired units, the customer is assured
of a fuel that is clean burning and ozone-friendly.
No CFCs
■ In addition to the extensive list of design benefits above, the
Carrier-Sanyo units are completely ozone safe and use no
CFCs or HCFCs.
■ All cooling is achieved utilizing a refrigerant with a proven
track record and ample supplies that is environmentally safe:
namely, water!
■ Additionally, since an absorption cycle is accomplished
without a large motor-compressor drive arrangement, the
customer can be assured of quiet, trouble-free, ultra-low
vibration operation.

The absorption cycle
The absorption cooling cycle, like the mechanical vapour
compression refrigeration cycle, utilizes the latent heat of
evaporation of a refrigerant to remove heat from the entering
chilled water. Vapour compression refrigeration systems use a
chlorine-based refrigerant and a compressor to transport the
refrigerant vapour to be condensed in the condenser. The
absorption cycle, however, uses water as the refrigerant and
an absorbent lithium bromide solution to absorb the
vaporized refrigerant. Heat is then applied to the solution to
release the refrigerant vapour from the absorbent. The
refrigerant vapour is then condensed in the condenser.
The basic single-effect absorption cycle (see Figure 1)
includes generator, condenser, evaporator and absorber with
refrigerant (liquid) and lithium bromide as the working
solutions. The generator utilizes a heat source (burner, steam
or hot water) to vaporize the diluted lithium bromide
solution. The water vapour that is released travels to the
condenser where it is condensed back into a liquid,
transferring the heat to the cooling tower water. Once
condensed, the liquid refrigerant is distributed over the
evaporator tubes, removing the heat from the chilled water
and vaporizing the liquid refrigerant. The concentrated
lithium bromide solution from the generator passes into the
absorber, absorbs the refrigerant vapour solution from the
evaporator and dilutes itself. The diluted lithium bromide
solution is then pumped back to the generator where the
cycle is started again.

■ The generator section is divided into a high-temperature
generator and a low-temperature generator. The refrigerant
vapour produced by the high-temperature generator is used to
heat the LiBr solution in the low-temperature generator in
which the pressure (hence the boiling point) is lower. Thus
the heat of condensation is effectively utilized.

■ As mentioned for the single-effect type, the refrigerant
vapour produced by the low-temperature generator is sent to
the condenser to become liquid refrigerant. On the other
hand, the refrigerant vapour produced by the hightemperature generator turns to water as it releases heat to the
intermediate LiBr solution. This happens inside the heat
transfer tubes in the low-temperature generator. The
refrigerant vapour produced by both low and hightemperature generators turns to refrigerant liquid and mixes
in the condenser before returning to the evaporator.

Absorption cooling cycle
■ The Carrier-Sanyo Super Absorption machine applies the
same basic absorption principles but enhances the cycle by
adding additional heat exchangers and a second generator to
recover all the available energy of the system and maximize
the unit COP (Figure 2).
The absorption cycle operates in a vacuum. This permits the
liquid refrigerant to boil at a lower temperature, transferring
the latent heat of evaporation from the entering chilled water
to cooling the chilled water.
The intermediate and concentrated solutions are cooled by
the diluted solution. This cooling process of the concentrated
solution allows for greater absorbing power due to its lower
temperature.
Line B to C to D’ of Graph 1 shows the temperature rise of
the diluted solution in the low and high-temperature heat
exchangers.

A. Evaporator section
Liquid refrigerant entering the evaporator is dispersed
uniformly on the chilled-water evaporator tubes (Figure 4).
The low pressure of the evaporator causes the refrigerant to
boil, thus vaporizing the refrigerant and causing the latent
heat of the vaporized refrigerant to cool the chilled water.
B. Absorber section
Concentrated solution entering the absorber is dispersed
uniformly on the cooling water tubes (Figure 4). The
concentrated solution in the absorber section absorbs the
refrigerant vapour from the evaporator section of the vessel.
Cooling water flowing through the absorber section heat
transfer tubes extracts the heat generated by this absorption
process. The concentrated solution, after absorbing the
refrigerant vapour from the evaporator, becomes a diluted
solution.
Line A to B in Graph 1 describes the process in the absorber.
The concentration of the lithium bromide solution entering
the absorber section is 63.5% (all concentration levels and
temperatures are approximate). The lithium bromide solution
then absorbs the refrigerant vapour from the evaporator
section and is cooled from 50°C to 37°C by the cooling
water. This causes the bromide solution to become diluted
and it then leaves the absorber at a concentration of 57.7%
(point B, Graph 1).
C. Low and high-temperature heat exchangers
The diluted solution, after leaving the absorber section,
passes through the low-temperature heat exchanger (see
Figure 5) where it is heated by the concentrated solution. The
diluted solution then passes through the high-temperature
heat exchanger where it is further heated by intermediate
solution.

D. High-temperature generator section
The diluted solution from the heat exchangers is heated by
the burner or steam upon entering the high-temperature
generator and separates into refrigerant vapour and intermediate solution (Figure 6).
Line D’ to E of Graph 1 shows the heating and concentration
process in the high-temperature generator. The diluted
solution at point D’ is heated at a constant concentration to
point D, where the refrigerant vapour is released and the
solution becomes concentrated to 60.8% (point E, Graph 1).
Following the intermediate solution, line E to F’ of Graph 1
shows heat transfer from the intermediate solution to the
diluted solution in the high-temperature heat exchanger
(Figure 5).
E. Low-temperature generator section
The refrigerant vapour from the high-temperature generator
passes through the heat transfer tubes of the low-temperature
generator (Figure 7). The intermediate solution from the
high-temperature heat exchanger passes to the lowtemperature generator where it is heated by the refrigerant
vapour. The heated intermediate solution releases additional
refrigerant vapour and becomes concentrated to its final
level. The condensed refrigerant in the heat transfer tubes and
the refrigerant vapour of the low-temperature generator
section then flows to the condenser.
Line F’ to F to G of Graph 1 shows the concentration process
in the low-temperature generator. The intermediate solution
enters the low-temperature generator and is heated by the
refrigerant vapour from the high-temperature generator.
Additional refrigerant vapour is released and the intermediate
solution becomes concentrated into its final concentration
level of 63.7% (point G, Graph 1).
Following the concentrated solution, Line G to A’ of Graph 1
shows the process of temperature reduction in the lowtemperature heat exchanger by heat transfer to the diluted
solution (Figure 5). Line A’ to A shows the temperature
reduction of the concentrated solution entering the absorber.

G. Refrigerant path and flow
In the high-temperature generator, the heat source separates
the refrigerant from the lithium bromide solution.
The lithium bromide solution follows line D to E of Graph 1.
Line D to H of Graph 1 follows the refrigerant path and
illustrates the change of refrigerant vapour to liquid as it
passes through the low-temperature generator. The refrigerant
then flows to the condenser (line H to I) where additional
heat is removed. In the low-temperature generator additional
refrigerant is released from the lithium bromide solution (line
F to G); this released refrigerant travels to the condenser (line
F to I) where it is condensed into a liquid. Point I represents
the combination of liquid refrigerant from both the lowtemperature generator and the condenser. The liquid
refrigerant flows into the evaporator where it mixes with
evaporator refrigerant and is pumped to the evaporator’s
dispersion trays (line I to J). The refrigerant is dispersed on
the evaporator heat transfer tubes and vaporizes; the vapour is
absorbed by the concentrated solution in the absorber causing
the bromide solution to become diluted (line J to B). The
diluted solution flows to the low-temperature heat exchanger
(line B to C) where the cycle is repeated.
Figure 7 - Upper shell

F. Condenser section
The refrigerant vapour from the low-temperature generator is
condensed on the cooling water heat transfer tubes of the
condenser (see Figure 7). The cooling water from the
absorber flows through the condenser and removes the heat
of condensation from the refrigerant vapour from the lowtemperature generator section and is rejected to the cooling
tower.

Heating cycle
In the absorption heating cycle the unit is essentially acting
as a boiler. Diluted solution is heated in the high-temperature
generator releasing refrigerant vapour from the absorbent.
The refrigerant vapour flows to the absorber/evaporator and
condenses on the heat transfer tubes of the evaporator. The
water through the evaporator heat transfer tubes removes the
sensible heat of the condensed refrigerant and transfers the
heat to the hot water loop. The condensed refrigerant is
mixed with the intermediate solution creating diluted
solution. The diluted solution is pumped back to the hightemperature generator where the cycle is started again.

Carrier-Sanyo control system
■ The Carrier-Sanyo control system surpasses other
proportional only control systems available today. The digital
PID (proportional plus integral plus derivative) control
maximizes unit performance by maintaining a ±0.5 K
variance in leaving chilled-water temperature from the
setpoint. Proportional controls can typically only maintain a
±1 K variance from the setpoint. The controller’s innovative
design also incorporates the ability to start and stop the
system chilled/hot and cooling water pumps. During
shutdown these pumps are sequenced to ensure a complete
dilution cycle.
■ The leaving chilled-water temperature is measured every five
seconds and fuel input is changed according to the gradient
of the leaving chilled-water temperature curve. System
temperatures, setpoints, and operational records are displayed
along with indicator lights for the chiller, pumps and burner.
■ The Carrier-Sanyo control system offers its users selfdiagnostics by constantly monitoring the chiller status and
will automatically shut the chiller down should a fault occur.
The cause of shutdown will be retained in memory and can
be displayed for immediate operator review. The controller’s
memory will also retain and display the cause of the last
three system fault conditions. This method of retaining fault
conditions is extremely useful for maintaining an accurate
record of unit performance and fault history.

Fast digital PID control
■ The introduction of new digital PID control to the J-model
stabilizes the chilled/hot-water temperature with higher
accuracy than the previous E-model. It quickly responds to
the load fluctuation and supplies stable chilled/hot-water
temperature. It is suitable for airconditioning of intelligent
buildings which require sophisticated control.
Microprocessor monitoring substantially reduces the
optimum dilution cycle period
■ This results in the appropriate dilution cycle operating hours.
Graph 7 - Dilution cycle chart
Control of high-temperature generator using solution
level control
■ With the new control system, the solution flow rate is
precisely controlled so that the solution level of the hightemperature generator is maintained at a certain level.
■ Control accuracy has been substantially increased through
the use of absorbent pump inverter control. This enables the
supply of a more stable temperature for chilled/hot water
compared to conventional models.

Sequence of cooling operation
■ Figure 14 illustrates the typical operating sequence of a
Carrier-Sanyo 16DJ direct-fired absorption chiller/heater.
■ With a chilled water setpoint of 6.7°C and with the
chillers/heaters enabled, the start signal will be energized as
the leaving chilled water temperature rises to 7.7°C, 1.0 K
above setpoint.
■ The burner initially completes a 36-second pre-purge
operation that includes gas valve and supply air damper
modulation to fully open to ensure complete purging of the
combustion chamber.
■ The No. 1 absorbent pump flow rate is changed during all
stages of operation to ensure quicker start-up and optimum
performance at part load.
■ As the cooling load is satisfied with the chillers/heaters at
minimum load, the unit will cycle off as the leaving chilledwater temperature drops to 5.5°C, 1.5 K below setpoint.
■ When the microprocessor issues a stop signal, the generator
heat source will shut off and the dilution cycle will start. The
dilution cycle will last between 6 and 15 minutes depending
on generator temperature. The dilution cycle will consist of
stopping of the refrigerant pump, absorbent pump(s), and the
cooling water pump in turn. The unit is capable of restarting
during the dilution cycle.

Sequence of heating operation
■ Figure 15 illustrates the typical operating sequence of a
Carrier-Sanyo 16DJ direct-fired absorption chiller/heater in
heating mode.
■ With a hot water setpoint of 55°C, the start signal will be
energized as the leaving heating water temperature drops to
54°C, 1.0 K below setpoint.
■ The burner initially completes a 36-second pre-purge
operation that includes gas valve and supply air damper
modulation to fully open to ensure complete purging of the
combustion chamber. The No. 1 absorbent pump flow rate is
varied during all stages of operation to ensure quicker startup and optimum performance at part load. On chillers/heaters
with two absorbent pumps, the No. 2 pump remains off at all
times during the heating mode.
■ As the heating load is satisfied with the chillers/heaters at
minimum load, the unit will cycle off as the leaving heating
water temperature rises to 57°C, 2 K above setpoint.
■ When the microprocessor receives a stop signal, the
generator heat source will shut off and the dilution cycle will
begin. The dilution cycle will last approximately 5 minutes
depending on generator temperature. The dilution cycle
consists of timed stopping of the No. 1 absorbent pump. The
chiller/heater is capable of restarting during the dilution
cycle.

Flue and stack connection
■ The flue and stack must be heat-insulated and provided with
a damper and a condensate drain.
■ The flue should never be connected to an incinerator stack.
■ Locate the top end of the smoke stack at a sufficiently large
distance away from the cooling tower.
■ If the same stack is used for discharging exhaust from two
systems, the back flow of exhaust gas should be prevented
from going into the inoperative unit.
■ Provide a draught regulator if fluctuations in static pressure
are expected inside the flue.
Typical steel stack
■ As illustrated, the steel stack should be lined on the interior
surface as a protection against corrosion due to exhaust gas.
Compliance with local regulations
■ In many areas local codes may regulate large capacity chillers
consuming oil or gas as fuel.
■ Such regulations should be strictly followed.

Burner description
■ The 16DJ direct-fired chillers/heaters are equipped with a
nozzle mix burner. The burners are capable of firing with
natural gas.
■ The burner is factory-wired and tested prior to shipment.
Manual modulation from low fire to high fire during start-up
and routine maintenance procedures are provided by an
operation switch on the chiller control panel.
■ The burner maximizes flame retention at all capacity ranges
of modulation, ensuring long life and efficient operation.

NOTE: In order to prevent freezing of the chilled water continue the operation of the primary and secondary chilled/hot-water
pumps during the dilution cycle of the chillers/heaters for about 15 minutes.
General remarks on piping
1. Equipment and parts outside the area surrounded by the
broken line are not supplied by Carrier.
2. For pipe connections and diameters refer to the dimensional
drawings.
3. Determine the location of the chilled/hot water pumps,
cooling water pump and expansion tank with due
consideration of the pump’s hydrostatic head.
The machine should not be subject to a pressure larger than
1034 kPa at any water headers.
4. Cooling water minimum entering temperature control has to
be supplied (see Installation Instructions).
5. It is recommended to have separate chilled/hot and cooling
water pumps for each chiller/heater.
6. During heating operation, cooling water must be discharged.
7. Provide a thermometer and pressure gauge at the chilled/ hot
and cooling water outlet and inlet pipe connections.
8. Provide an air vent valve in each of the chilled/hot and
cooling water lines at a point higher than each header.
9. Drain pipes from the evaporator, absorber and smoke
chamber should be piped to the drain channel.
30
10. Provide an expansion tank in the chilled/hot-water line.
11. Provide a blow-down valve in the cooling water line for water
quality control.
12. There should be sufficiently large clearances for easy access
to the evaporator, absorber and condenser, to facilitate
inspection and cleaning.
13. Provide heat insulation to the flue, which should be equipped
with a damper and condensate drain.
14. Do not connect the flue to the smoke stack of an incinerator.
15. If one flue is used for two or more chillers/heaters, a device
should be provided to prevent the flow of exhaust gas into the
inoperative unit.
16. The exhaust discharge end of the flue should be kept a
sufficient distance away from the cooling tower.
17. If the static pressure inside the flue is subject to fluctuations
provide a draught regulator.
18. If necessary, fit the rupture disk on the chillers/heaters
according to the rupture disk manual.
19. All external water piping with ANSI 150 LB welding flanges
is to be provided by the customer.
Safety considerations
Before operating the unit
■ Before operating the unit be sure to read the operation
manual carefully.
■ Installation should conform to all applicable local codes and
regulations.
During the installation
■ Read the installation manual carefully before offloading and
installing the unit.
■ All work must be carried out by qualified personnel to
prevent injuries and damage to the equipment.
■ Consult your service office, if work on the flue, exhaust and
intake air duct and chimneys is required. If this type of work
is not correctly completed, scalding, fire and oxygen
deficiency may occur.
■ Waterproof the unit foundation and provide a drain channel
to prevent water damage to the surrounding equipment.
■ Provide adequate space around the unit for maintenance work
to ensure safe working conditions.
Maintenance
■ In addition to daily inspection periodical maintenance is
required. Insufficient or incorrect maintenance may cause
fire, electric shock and injuries.
■ Please consult your local service office for further guidance.
Avoiding hazardous places
■ Keep the units away from dangerous inflammable substances
such as gasoline, thinner and combustible gases, as these may
result in a fire.
