Carrier compressors deliver quiet, reliable high-cooling capacity at low cost. Compressor motor protection - assured on all units by use of quick-sensing elements that prevent trouble before it starts. Quiet, high-capacity fans - move large volumes of indoor air quietly and at a lower rpm than most comparable fans. Compact housing and specially designed discharge give fans superior air handling capability. Evaporator coils - Space saving slab type provides high heat transfer efficiency with large face area; fins are mechanically bonded to seamless copper tubing for high-capacity performance. High-efficiency condensers - shell and tube construction provide maximum exposed surface for more heat rejection with less water. Crankcase heaters - remain on during compressor off cycle to prevent dilution of oil by refrigerant...thus, preventing flooded parts. 5

6 Selection procedure (with example) 1. Determine job requirements. Given: Cooling load (TC:Btu/h) 270,000 (SHC:Btu/h) 197,000 Evap. air quantity (cfm) 8,000 Evap. entering air conditions wb 67 F db 80 F Condenser entering water temp 90 F Condenser leaving water temp 100 F External static pressure (in WG) Select unit(s) based on cooling requirements. A. B. Enter Cooling Capacities tables at given evaporator air quantity (8,000 cfm.) and condenser leaving water temperature (100 F). By interpolation, if required, determine total cooling capacity (TC) and sensible heat capacity (SHC) at given evaporator entering air wb (67 F). A BY025 unit has a capacity of 271,800 Btu/h (TC) and 197, Btu/h (SHC). Correct the SHC value for evaporator entering air db temperature other than 80 F. For this example, no correction is required. The unit can satisfy specified cooling load requirement. 3. Determine required fan motor kw and fan rpm. A. Determine total static pressure by adding unit internal pressure drop to a specified external S.P. From BY025 fan curve, pressure drop for unit is found to be 0.4 in. WG. at the specified air quantity (8,000 CFM). Total S.P. = = 3.20 in. WG. Locate on the curve where the specified air quantity and total S.P. (3.20) intersect. The intersect point is under 3.7 kw line and fan rpm can be determined as 920 rmp. The standard 3.7 kw motor can satisfy the requirements. 4. Determine condenser water requirements. A. Required water flow can be determined using formula below: B. GPM = TC(Btuh)+Compressor Power Input(KW)x x Rise ( F) = x3414 = x (100-90) Enter Condenser Pressure Drop table at the determined water flow (66.58 gpm.). Interpolate, if required, to optain the water pressure drop (4.98 PSI). A proper water pump can be selected based on this value. Fan performance 1. The fan performance curves are based on dry coil and clean Filters. 2. Total static pressures are shown on the vertical scale of the chart. To determine external static pressure, deduct Unit Pressure Drop (casing loss bottom curves) from the total S.P. value read at a given air quantity. 3. The kw values denote fan motor nominal output. The nominal 1.5 kw motor, for example, can cover the areas of Air Qty. Total S.P. and rpm shown under the line indicated as 1.5 kw. 4. Use curves within the ranges shown. Do not exceed the ranges. Motor selection The power curve shown on every diagram represents the absorbed power at the shaft after fan measured in kw. To determine the power of the motor to be installed, the following correct factors have to be taken in consideration. For power less than 10 kw x 1.2 For power more than 10 kw x 1. 6
