Incorrect or incomplete analysis/ design of the water loop could lead to low water flow, loss of water temperature control, and excessive cycling of chiller compressors. The following are the steps for verification of water pump capacity for the APC chillers (refer to Pump Curve tables). 1. Provide the total water pressure drop of the system external to the APC chiller based on the total water flow rate required. 2. Determine the internal pressure drop of the chiller hydronic package based on the design flow rate (refer to internal Pressure Drop tables on page 24). Values given in these charts are based on units with clean strainers and circuit setter valves wide open. 3. If an optional storage tank is used, determine the internal pressure drop by referencing the internal Pressure Drop tables on page 25. 4. Add pressure drops found in Steps 1-3. This is the total pressure drop and total head required by the pump. 5. Use the pump curves table on page 23 to determine pump capacity. Plot water flow rate (Step 1) and total head (step 4) on the chart. If the point is below the pump curve, then the pumps included in the chiller have enough capac- ity to operate at the design conditions. 22 APC Air Cooled Chillers Selection Procedure ACCH050 - 084 Pump Curve ACCH120 - 167 Pump Curve ACCH200-220 Pump Curve APC Air Cooled Chillers 23 Selection Procedure ACCH050 - 084 Chiller Pressure Drop Curves Note: Curve 2 represents ACCH050 and Curve 5 represents ACCH084.

They perform four impor- tant functions: 1) provide for expansion of the liquid as the temperature in the system rises, 2) act as a pressure reference for the system, 3) supply sufficient pressure to prevent cavitation, 4) provide a location to charge the system. Chiller models ACCH050 – 167 hydronic package includes a bladder-style expansion tank, pre-charged to 40 psig (277 kPa) pressure and pre-selected for loop volumes up to 6 gallons per ton. If loop volumes in excess of 6 gallons per ton are required, then a field-installed expansion tank must be provided, and the expansion tank in the chiller’s hydronic package must be removed. For maximum loop volumes see page page 38. If the top of the piping system (the highest point in the hydronic piping) is more than 80 ft (24 m) above the chiller, then the expansion tank will require additional air pressure charge. The expansion tank must be pressurized to pro- vide at least 4 psi (28 kPa) of positive pressure at the highest point in the hydronic piping system. This will also ensure no air is drawn into the piping. The amount of charge pressure in pounds per square inch (psi) that is required in the expansion tank is equal to 4 psi (28 kPa) plus the height from the chiller to the highest point in the hydronic system divided by an X factor for setting tank pressure as shown below. “X” Factor for Setting Tank “X” Factor for Setting Tank Pressure Pressure English (ft, psi) SI (m, kPa) Ethylene Propylene Ethylene Propylene % Glycol % Glycol Glycol Glycol Glycol Glycol 0 (pure 0 (pure 2.31 2.31 0.102 0.102 water) water) 10 2.36 2.33 10 0.104 0.103 20 2.38 2.36 20 0.105 0.104 30 2.40 2.38 30 0.106 0.105 40 2.43 2.38 40 0.108 0.105 50 2.47 2.40 50 0.109 0.106 Maximum Tank Working Pressure is 150 psig (1034 kPa). Note Example: (English Units) APC chiller elevation is 10 feet. The hydronic system is piped to a data center on the top floor with an elevation of 100 feet. Fluid is 100% water. The total pressure required in the expansion tank is: 4 psi + (100 ft – 10 ft)/2.31 = 42.96 psig The expansion tank will require an additional 3 psi pressure. Example: (SI Units) APC chiller elevation is 3.05 meters. The hydronic system is piped to a data center on the top floor with an elevation of 30.5 meters. Fluid is 100% water. The total pressure required in the expansion tank is: 28 kPa + (30.5 m – 3.05 m)/.102 = 297.11 kPa The expansion tank will require an additional 21 kPa pressure. 26 APC Air Cooled Chillers Typical Piping — Chiller to Cooling Distribution Unit (CDU) (50-167 kw) CHILLER RC CDU Components inside dashed lines are included with the chiller, InfraStruXure InRow RC, and CDU.

APC Air Cooled Chillers 33 CHILLER 1 CHILLER 2 na2292a Typical Piping — Redundant Chillers (200-220 kw) 34 APC Air Cooled Chillers Application Data Chiller Location and Clearances Do not locate the chiller near sound sensitive areas without proper acoustic consideration. For applications requiring mounting a chiller on a building rooftop, consideration should be given to using rubber-in-shear or spring isolators to minimize structure-borne transmission. Unit must be level when installed to ensure proper oil return to the compressors. Clearances must be provided around chillers for airflow, service and local code requirements. See dimensional drawings for specific unit clearance requirements. Ensure ade- quate clearance between adjacent chillers is maintained. A minimum of 10 ft (3048 mm) is recommended. Chiller fan discharge must be at least as high as adjacent solid walls. Installation in pits is not recommended. Oversizing Chillers Oversizing chillers by more than 15% at design conditions must be avoided as the system operating effi- ciency is adversely affected (resulting in greater or excessive electrical demand). When future expansion of equipment is anticipated, install a single chiller to meet present load requirements and add a second chiller to meet the additional load demand. It is also recommended that 2 smaller chillers be installed where oper- ation at minimum load is critical. The operation of a smaller chiller loaded to a greater percentage over minimum is preferred to operating a single chiller at or near its minimum recommended value. Minimum Load Control should not be used as a means to allow oversizing chillers. Minimum Load Control should be given consideration where substantial operating time is anticipated below the minimum unloading step. Cooler Fluid Temperature 1. Maximum leaving chilled fluid temperature (LCWT) for units ACCH050, 084, 120 & 167 is 70°F (21°C). Maximum LCWT for unit ACCH200 and ACCH220 is 85°F (29°C). Units can start and pull down with up to 95°F (35°C) entering-fluid temperature. It is recommended that entering- fluid temperature not exceed 85°F (29°C). 2. Minimum LCWT for standard unit is 40°F (4.4°C). For leaving-fluid temperatures between 34° to 39.9°F (1° to 4.39°C) a 20% anti-freeze solution, or greater is required. NOTE: Water flowing through cooler should not exceed 100°F (38°C). Cooler Flow / Range Ratings and performance data in this publication are for a cooling temperature rise of 10°F (6°C). APC Chillers may be operated at a different temperature rise, providing flow limits are not exceeded and correc- tions to the system guidelines are made. For minimum cooler flow rates, see the Minimum and Maximum Cooler Flow Rates table. A high flow rate is generally limited by the maximum pressure drop that can be tolerated by the unit. If another temperature range is used, apply LCWT correction as given in the Selec- tion Procedure example on page 21. APC Air Cooled Chillers 33 Application Data Minimum Cooler Flow (Maximum Cooler Temperature Rise) The minimum cooler flow for standard units is shown in Minimum Cooler Flow Rates table. When system design conditions require a lower flow (or higher rise) than the minimum allowable cooler flow, follow the recommendations below. a. Multiple smaller chillers may be applied in series, each providing a portion of the design tempera- ture rise. b. Cooler fluid may be recirculated to raise the flow rate to the chiller. However, the mixed tempera- ture entering cooler must be maintained a minimum of at least 5°F (2.8°C) above the LCWT NOTE: Recirculation flow is shown below. Maximum Cooler Flow The maximum cooler flow (> 5 gpm/ton or < 5°F rise [> 0.09 L/s · kW or < 2.8°C rise]) results in practical maximum pressure drop through the cooler. Return fluid may bypass the cooler to keep the pressure drop through the cooler within acceptable limits. This permits a higher ΔT with lower fluid flow through the cooler and mixing after the cooler. NOTE: Bypass flow is shown below. Variable Cooler Flow Rates Variable rates may be applied to the standard chiller. Unit will, however, attempt to maintain a constant leaving chilled fluid temperature. In such cases, the minimum flow must be in excess of the minimum flow given in the Min- imum Cooler Fluid Flow Rates and Minimum Loop Volume table, and flow rate must change in steps of less than 10% per minute. Apply 6 gal. per ton (6.5 L per kW) water loop volume if the flow rate changes more rapidly. 34 APC Air Cooled Chillers Application Data Tank Volume* A properly baffled storage tank is available as an accessory. These tanks are designed to physically fit beneath the corresponding ACCH unit, taking up the same footprint. Available volume is as follows: ACCH050 - 110 gallons (416 liters) ACCH084 - 150 gallons (567 liters) ACCH120 & 167 - 305 gallons (1154 liters) *ACCH200 and ACCH220 - Field Supplied Note: All tanks must be field installed.

To achieve this volume, it is often necessary to install a tank in the loop. Tank should be baffled to ensure there is no stratification and that water entering tank is adequately mixed with liquid in the tank. APC Air Cooled Chillers 35 Application Data Cooler Fouling Factor The fouling factor used to calculate tabulated ratings was 0.0001 ft² · hr · °F/Btu (0.000018 m² · °C/kW). As fouling factor is increased, unit capacity decreases and compressor power increases. Corrections to published ratings can be approximated by using following multipliers: Fouling Factors Fouling Factor Fouling Compressor Capacity (English) Factor (SI) Power Multiplier 2 2 (ft ·hr·°F/Btu) (m ·C/kW) Multiplier 0.00025 0.000044 0.991 0.995 0.00050 0.000088 0.977 0.987 0.00075 0.000132 0.955 0.979 0.00175 0.000308 0.910 0.952 Cooler and Hydronic System Freeze Protection Protection against low ambient freeze-up is required for unit operation in areas that experience temperatures below 32°F (0°C). Protection should be in the form of inhibited ethylene glycol or other suitable brine. Even though the unit cooler is equipped with insulation and an electric heater that helps prevent freeze-up, it does not protect fluid piping external to cooler or if there is a power failure. Use only antifreeze solutions approved for heat exchanger duty. Use of automotive-type antifreezes is not recommended because of the fouling that can occur once their relatively short-lived inhibitor breaks down. Draining the cooler and outdoor piping is recommended if system is not to be used during freezing weather conditions. See Low Ambient Temperature Operation section. High Ambient Temperature Operation High outdoor ambient chiller start-up and operation (fully loaded) is possible for standard APC Chillers at ambient temperatures up to 120°F (50°C) (sizes 050, 084, 120 & 167) and 125°F (52°C) (size 200 and 220) at nominal voltage. Low Ambient Temperature Operation Units will start and operate down to -20°F (-29°C) as standard. Operation at -20°F (-29°C) is achieved with the Motormaster® V condenser head pressure control as well as wind baffles (provided and installed in the field by others to all units for operation below 32°F (0°C) if wind velocity is anticipated to be greater than 5 mph (8 km/h). Inhibited propylene glycol or other suitable corrosion-resistant anti- freeze solution must be field supplied and installed in all units for unit operation below 32°F (0°C). Solution must be added to the fluid loop to protect loop down to 15°F (8°C) below minimum operating ambient temperature. Concen- tration should be based on expected minimum temperature and either “Burst” or “Freeze” protection levels. At least 6 gal per ton (6.5 L per kW) of fluid volume is recommended minimum for a moderate system load. 36 APC Air Cooled Chillers Application Data Altitude Correction Factors Correction factors must be applied to standard ratings at altitudes above 2000 ft (610 m) using the following multipliers: Altitude Correction Factors Compressor Altitude Altitude Capacity Power (ft) (m) Multiplier Multiplier 2,000 610 0.99 1.01 4,000 1220 0.98 1.02 6,000 1830 0.97 1.03 8,000 2440 0.96 1.04 10,000 3050 0.95 1.05 Freeze Versus Burst Protection If chiller operation is not required during winter/off season, lower glycol concentrations based on “burst” protection criteria should be considered. Often the use of burst protection results in lower fluid costs and has less impact on chiller cooler capacity and flow rate. Consult glycol fluid manufacturers for burst protection recommendations and fluid specifications. Multiple Chillers Where multiple chillers are required, or where standby capability is desired, chillers may be installed in parallel. The flow must be balanced according to the recommendations for each chiller. Where applied in parallel with optional hydronic package, the expansion tank must be disconnected and a single expansion tank must be installed in the common header. Unit software is capable of controlling two units as a single plant. Refer to Controls, Start-Up, Operation, Service, and Troubleshooting guide for further details. Hydronic pump packages may not be applied in series applications. APC Air Cooled Chillers 37 Application Data Remote On-Off Control Remote on-off control may be applied by hard-wired connection (see Controls and Troubleshooting literature). Hydronic System and Expansion Tank Selection Select pump GPM from resulting chiller selection and total pressure loss in the system plus the chiller internal pres- sure loss. NOTE: The maximum gpm (L/s), pressure and pump hp must not exceed the maximum on the pump curve. Pump glow can be reduced using the factory-supplied balancing valve up to 10%. Beyond that, impeller trimming is recommended to reduce energy consumption. Follow local codes or ASHRAE 90.1 recommendations. Contact your APC representative for the specific amount of trim required. The expansion tank supplied will allow loop expansion due to ambient fluctuations for loop volumes of up to the val- ues in the Max Loop Volume table. If the loop volume exceeds this volume, a larger expansion tank must be field supplied. ACCH050-084 4.4 total gal., 3.2 acceptable volume (16.6 total liters, 12.1 acceptable volume) ACCH120-167 10.3 total gal., 10.3 acceptable volume (38.9 total liters, 38.9 acceptable volume) Max Loop Volume (gal) ACCH050-084 ACCH120-167 Pure Water 310 (1173) 725 (2744) 10% EG 180 (681) 425 (1608) 20% EG 175 (662) 410 (1551) 30% EG 155 (586) 370 (1400) 40% EG 150 (567) 350 (1324) 10% PG 175 (662) 410 (1551) 20% PG 150 (567) 350 (1324) 30% PG 128 (484) 300 (1135) 40% PG 118 (446) 275 (1040) EG - Ethylene Glycol PG - Propylene Glycol NOTE: The maximum loop volume is based on typical system of 12 psi (82.7 kPa) and 30 psi (206.85 kPa) on min/ max pressures, and 100°F (37.8°C) mean temperature. If the volume in the system is greater than the limits listed below, then extra expansion tank volume must be added to the system. The ACCH200 and ACCH220 chillers will require a field supplied expansion tank. The expansion tank is based on fluid type, temperature range, fluid pressure and loop volume. Parallel chillers with hydronic packages require that pump inlets be equalized to prevent pump cavitation. Pump expansion tanks must be removed and located together in the common pump suction header. All materials needed for expansion tank relocation are field supplied. Appropriate measures must be taken for freeze protection. 38 APC Air Cooled Chillers Application Data Air Separation APC chillers will require a field-supplied air separation device. Air must be controlled in a hydronic system if it is to perform properly. Air can block the flow of chilled water to its destinations and can cause cavitation in the pump, which will aerate the pump and potentially cause pump failure. The air separator is sized according to the total flow through the system. The air sepa- rator should be located inside the building. There are several types of air separators to choose from. For more information and product selection contact your local manufacturer’s representative.
