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 Outdoor package CCHP system Azar Nasim outdoor packages are warm & hot water types small & medium models additionally equipped with hot water boiler, cooling tower, cooling water pumps , chilled water pumps & hot water pumps . The perfect combination between Azar Nasim absorption chillers and turbo generator or Diesel generator made in the U.S.A. , Europe or any other countries Can increase the energy efciency greatly. 27 28 LIQUID CHILLER (Water and Air Cooled Chiller) 29 Liquid Chiller (Water & Air Cooled Chiller) Features Azar nasim reciprocating water chillers are available in two types of air cooled and water cooled in capacity range of 3 to 240 tons of refrigeration and compressor configurations of one to four. Evaporators and condensers are high efficiency shell and tube heat exchangers which designed based on time (Tubular Exchanger Manufactures Association) standards. Safety controls installed on all units include high and low pressure cut-outs, compressor oil pressure safety cut out, water anti freeze thermostat, water flow switch and evaporator entering water thermostat. The above mentioned are all chosen from the most recognized controlled manufacturers in the air conditioning industry. Compressors are by DWM COPELAND which happened to be one of the best and the most reliable brands. Raw materials such as copper tubes, fittings and valves are supplied by well-respected manufacturers. Electrical safety measures such as three phase controller, circuit breakers are available on all units. A fault detection system for the whole unit is available upon request. Microprocessor based PLC controller is also available as needed. 30 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. 31 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 = 24 24 45.83 tons of refrigeration 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.

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. HOT WATER IN MOIST, WARM AIR OUT • • • Environment wet bulb temperature: lowering wet bulb temperature. increasing fill area. increasing the period of air and water contact. 7. Terminology Range - The range is the temperature difference between the water inlet and water outlet. The capacity of a cooling tower can be calculated by measuring the water flow rate HOT WATER IN DRY AIR IN DISTRIBUTION BASIN AIR FLOW COLD WATER OUT WATER FLOW FILL MATERIAL COLLECTION BASIN CROSSFLOW TYPE DESIGN Counter flow In a counter flow design the air flow is directly opposite of the water flow (see diagram below) Air flow first enters an open area beneath the fill media and is then drawn up vertically. The water is sprayed through pressurized nozzles and flows downward through the fill, opposite to the air flow. MOIST, WARM AIR OUT FAN DISTRIBUTION SYSTEM HOT WATER IN SPRAY NOZZLES AIR FLOW WATER FLOW FILL MATERIAL DRY AIR IN 6. Factors which effects the capacity of cooling tower FAN DRY AIR IN 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. COLD WATER OUT 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. 14. Advantages of "Tahvieh Azar Nasim" Cooling Towers: • • Strong FRP layers used isophetalic resin, no vibration and increase the life of cooling tower. Neopentyl glycol (NPG) anti-UV causes long lasting color, decorative and long life. • • • • • FRP sump Fill are made of Virgin antibacterial PVC films. Fans are dynamically balanced for smooth operation, longer bearing life including that of the supporting structure. The fan drive motor is in IP-55, F class. 5years warranty insures you a right purchase. 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, 55 FAN GUARD MOTOR SUPPORT GEAR DRIVE FAN LADDER SPRINKLER BELL MOUNT STAND PIPE ELIMINATOR CASING SUPPORT POST FILLER LOUVER BASIN SUPPORT 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. 56 FILLER SUPPORT WATER BASIN 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. 17. Preparation for Installation 1.

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.

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. 67 Table 6 Model GPM Dimensions (mm) Motor power Kw Length Width Height 700 700 1300 0.37 Inlet (inch) 1 Outlet (inch) Weight (Kg) Dry Full 1 45 105 49.1 20 49.2 30 700 700 1450 0.37 1 1 56 128 49.3 40 700 700 1600 0.55 1 1 65 140 72.1 50 850 850 1740 0.55 2 2 115 240 72.2 60 850 850 1740 0.55 2 2 121 250 72.3 80 850 850 2040 0.75 2 2 127 260 169.1 90 1300 1300 2320 0.75 3 3 270 587 169.2 135 1300 1300 2320 1.1 3 3 290 660 169.3 150 1300 1300 2320 1.5 3 3 310 695 272.1 186 1650 1650 2360 1.5 4 4 390 1220 272.2 218 1650 1650 2360 2.2 4 4 410 1330 272.3 235 1650 1650 2660 2.2 4 4 430 1450 361.1 265 1900 1900 2590 2.2 4 4 645 1510 361.2 290 1900 1900 2590 3 4 4 680 1620 361.3 320 1900 1900 2890 3 4 4 720 1740 528.1 400 2400 2200 2650 3 2x3 6 895 2950 528.2 460 2400 2200 2650 4 2x3 6 950 3075 528.3 500 2400 2200 2950 5.5 2x3 6 1000 3270 748.2 570 3400 2200 3620 5.5 2x4 6 1300 4100 748.3 720 3400 2200 3920 7.5 2x4 6 1380 4490 967.2 815 4300 2200 3690 7.5 2x4 6 1450 5150 967.3 890 4300 2200 3690 11 2x4 6 1550 5550 1333.1 1150 4300 3100 4100 11 3x3 2x4 2230 8300 1333.2 1300 4300 3100 4100 11 3x3 2x4 2385 8500 1333.3 1430 4300 3100 4100 15 3x3 2x4 2510 8700 1849.1 1600 4300 4300 4000 15 3x4 2x6 3050 11050 1849.2 1770 4300 4300 4000 18.5 3x4 2x6 3240 11250 1849.3 1840 4300 4300 4000 22 3x4 2x6 3410 11850 68 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) MOTOR FRP. FAN FRP.

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.

The Leaving Dry Bulb temperature can be calculated using the following relation: LDB = EDB - 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 selected for the fan: RPM = 512 HP = 10 LDB = EDB - SHC 1.087 xCFM 105700 = 62.3 °F 1.087 x5500 The Leaving Wet Bulb temperature can be calculated according to the following method: LDB = 80 °F - EXAMPLE 2: Water Cooled Model Given: SUMMER CONDITION Total Cooling Load (TC)......................206 MBH Sensible Heat Capacity (SHC)............103 MBH Air Flow Rate....................................5500 CFM Entering Dry Bulb Temp.

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 77 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.

The face velocity, FV, is calculated according to the following relation: Table 3 -ALTIYUDE CORRECTION FACTOR ALTITUTE (m) CF ALTITUDE (m) CF 0 1.000 1400 1.107 310 1.023 1550 1.119 625 1.047 1720 1.132 940 1.070 1880 1.145 1250 1.095 2000 1.158 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. 78 TC = 35.83 - 262000 = 24.9 BTU/Ib 4.5 x CFM 4.5 x 8800 WATER COOLED PACKAGED UNIT RATINGS TABLE 4 EWT

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.

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.

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. 120 PACKAGED UNIT PIPING WATER FROM CONDENSER COOLING TOWER WATER TO CONDENSER AIR SUPPLY DUCT WATER COOLED PACKAGE UNIT CIRCULATING PUMP FIGURE 13.

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.

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%. 158 Note: Abbreviations Ent & Lvg. notes air Entering & Leaving air washer.

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. 166 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. 167 Dimensions for All Condensers W ELECTRICAL PANEL HOT GAS ENT.

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) 900 650 1 5 7 40 9 A 1 1 6 270 12 5 4 *supply Duct Collar Is Bx270 For All Horizontal Models. 4 40 15 635 40 15 1 1 6 170 10 4 40 390 12 11 RETURN AIR 11 365 SUPPLY AIR 6 12 10 35 40 3 255 C 50 SUPPLY AIR 9 6 410 12 10 RETURN AIR 7 11 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

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. 215 General Industrial Unit Heaters Figure 1 Model L W H A B C D E F G TU 40w-60S 500 350 500 300 120 80 100 410 2700 TU 50w-75S 500 350 500 300 120 80 100 410 TU 70w-115S 580 350 580 390 120 80 100 TU 80w-140S 580 350 580 390 120 80 TU 120w-160S 660 350 660 460 120 TU 150w-230S 750 350 750 540 TU 180w-280S Water (Inch) Steam (Inch) In Out In Out 6500 1 1 1 3/4 3000 8800 1 1 1 3/4 410 3200 9100 1 1 1 3/4 100 410 4000 12000 1 1 1 3/4 80 100 410 4000 13000 1 1/4 1 1/4 1 1/4 1 120 80 100 410 4000 14000 1 1/4 1 1/4 1 1/4 1 750 350 750 540 120 80 100 410 4500 14500 1 1/4 1 1/4 1 1/4 1 TU 200w-300S 810 350 810 610 120 80 100 410 4500 15000 1 1/4 1 1/4 1 1/4 1 TU 250w-400S 850 350 850 650 120 80 100 410 4500 16000 1 1/4 1 1/4 1 1/4 1 Note: All Dimensions in mm 216 Table -Hot Water Unit Heater Ratings Model Air Flow CFM BTU/hr. 1400 RPM Water Flow GPM Water Pressure Drop (Ft.Wg) MOTOR Amps Power (w) TU 40w 1300 42000 4.2 0.55 120 0.6 TU 50w 1400 54000 5.4 0.62 120 0.6 TU 70w 1900 74000 7.4 0.92 150 0.7 TU 80w 2100 82000 8.2 1.15 150 0.7 TU 120w 2400 120000 12 1.4 170 0.8 TU 150w 3000 155000 15.4 3 170 0.8 TU 180w 3500 180000 18 3.7 170 0.8 TU 200w 3700 220000 22 3.5 170 0.8 TU 250w 3900 260000 26 4 170 0.8 Table 3 -Hot Heater Ratings 900Flow RPM Water Air Water Flow Unit BTU/hr.

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.
