Anleitung Zusammenfassung
Unit 036 at 1225 cfm and 67 F ewb (entering wet bulb) will provide a total capacity of 36,500 Btuh and a SHC of 27,600 Btuh. Calculate SHC correction, if required, using Note 4 under Cooling Capacities tables. III SELECT HEATING CAPACITY OF UNIT TO PROVIDE DESIGN CONDITION REQUIREMENT. In the Heating Capacities and Efficiencies table on page 4, note that the unit 036090 will provide 70,000 Btuh with an input of 90,000 Btuh. IV DETERMINE FAN SPEED AND POWER REQUIREMENTS AT DESIGN CONDITIONS. Before entering the air delivery tables, calculate the total static pressure required. From the given example, the Wet Coil Pressure Drop Table, and the Filter Pressure Drop table on page 16, find at 1200 cfm: Wet Coil Pressure Drop 0.032 in. ws External Static Pressure 0.2 in. wg Filter Pressure Drop 0.13 in. wg Total Static Pressure 0.362 in. wg Enter the table for Dry Coil Air Delivery — Horizontal and Downflow Discharge. At 0.362 ESP (external static pressure), the fan will deliver 1235 cfm with the NOM Speed pin selected. V SELECT UNIT THAT CORRESPONDS TO POWER SOURCE AVAILABLE. The Electrical Data table shows that the unit is designed to operate at 208/230-1-60. —12— PERFORMANCE DATA STANDARD INDOOR ECM MOTOR COOLING CAPACITIES 574B024 COOLING PERFORMANCE TABLE Evaporator Air — CFM / BF Temp (F) 800/0.026 900/0.032 1000/0.04 Entering Condenser Evaporator Air — Ewb (F) 62 63* 67 72 62 63* 67 72 62 63* 67 72 75 TC SHC kW 24.0 21.9 1.7 24.5 21.3 1.7 26.5 18.7 1.8 29.1 15.4 1.8 24.6 23.5 1.8 25.1 22.8 1.8 27.1 19.8 1.8 29.8 16.1 1.8 25.1 25.0 1.8 25.5 24.2 1.8 27.4 20.8 1.8 30.4 16.7 1.9 85 TC SHC kW 22.9 21.4 1.9 23.3 20.7 1.9 25.3 18.1 2.0 27.9 14.9 2.0 23.5 22.9 2.0 23.9 22.2 2.0 25.8 19.2 2.0 28.5 15.6 2.0 23.9 24.3 2.0 24.3 23.6 2.0 26.2 20.3 2.1 28.9 16.2 2.1 95 TC SHC kW 21.8 20.8 2.2 22.2 20.2 2.2 24.0 17.6 2.2 26.5 14.3 2.2 22.3 22.3 2.2 22.6 21.6 2.2 24.5 18.7 2.2 27.0 15.0 2.2 22.7 23.6 2.2 23.0 22.9 2.2 24.8 19.7 2.3 27.4 15.6 2.3 105 TC SHC kW 20.5 20.2 2.4 20.9 19.5 2.4 22.6 16.9 2.4 25.0 13.7 2.4 21.0 21.6 2.4 21.3 20.9 2.4 23.0 18.0 2.5 25.4 14.3 2.5 21.6 22.5 2.5 21.7 22.2 2.5 23.3 19.0 2.5 25.7 14.9 2.5 115 TC SHC kW 19.2 19.4 2.7 19.5 18.8 2.7 21.1 16.3 2.7 23.3 13.0 2.7 19.8 20.6 2.7 19.9 20.2 2.7 21.5 17.3 2.7 23.7 13.7 2.7 20.7 21.5 2.7 20.4 21.2 2.7 21.7 18.3 2.8 23.6 14.1 2.8 125 TC SHC kW 17.8 18.5 2.9 18.0 18.1 2.9 19.4 15.5 3.0 21.4 12.3 3.0 18.5 19.2 3.0 18.5 19.2 3.0 19.5 16.5 3.0 21.7 12.9 3.0 19.0 19.8 3.0 19.0 19.7 3.0 19.9 17.6 3.1 21.9 13.5 3.1 574B030 COOLING PERFORMANCE TABLE Temp (F) Outdoor Air Entering Condenser Evaporator Air—CFM/BF 875/0.08 1000/0.09 1125/0.10 Evaporator Air — Ewb (F) 62 63* 67 72 62 63* 67 72 62 63* 67 72 75 TC SHC kW 85 TC SHC kW 95 TSk 105 TC SHC kW 115 TC SHC kW 125 TC SHC kW See Legend and Notes on page 15. —13— PERFORMANCE DATA (cont) STANDARD INDOOR ECM MOTOR COOLING CAPACITIES (cont) 574B036 COOLING PERFORMANCE TABLE Temp (F) Outdoor Air Entering Condenser Evaporator Air—CFM/BF 1100/0.06 1225/0.07 1400/0.08 Evaporator Air — Ewb (F) 62 63* 67 72 62 63* 67 72 62 63* 67 72 TC 36.2 36.8 39.7 43.8 36.9 37.4 40.3 44.4 37.9 38.1 41.0 45.1 75 SHC 33.2 26.7 27.8 22.3 34.7 27.9 29.0 23.1 36.9 29.6 30.9 24.2 kW 2.7 2.7 2.7 2.7 2.7 2.7 2.7 2.8 2.8 2.8 2.8 2.9 TC 34.6 35.1 37.9 41.8 35.3 35.6 38.4 42.4 36.4 36.3 39.1 43.1 85 SHC 32.4 26.0 27.1 21.6 34.0 27.1 28.3 22.4 35.6 28.9 30.2 23.6 kW 2.9 2.9 3.0 3.0 3.0 3.0 3.0 3.0 3.1 3.1 3.1 3.2 TC 33.0 33.4 36.0 39.7 33.7 33.8 36.5 40.2 34.8 34.4 37.0 40.8 95 SHC 31.6 25.3 26.4 20.9 32.9 26.4 27.6 21.7 34.4 28.1 29.4 22.8 kW 3.2 3.2 3.3 3.3 3.3 3.3 3.3 3.4 3.4 3.4 3.4 3.5 TC 31.3 31.5 34.0 37.5 32.1 31.9 34.3 37.9 33.1 32.4 34.9 38.4 105 SHC 30.6 24.5 25.6 20.1 31.5 25.7 26.8 20.9 32.8 27.3 28.6 22.0 kW 3.6 3.6 3.6 3.6 3.6 3.6 3.7 3.7 3.8 3.7 3.8 3.8 TC 29.6 29.4 31.8 35.0 30.4 29.8 32.1 35.4 31.3 30.3 32.6 35.8 115 SHC 29.3 23.7 24.8 19.3 30.0 24.8 26.0 20.0 31.0 26.4 27.7 21.1 kW 4.0 4.0 4.0 4.0 4.0 4.0 4.0 4.0 4.1 4.1 4.1 4.2 TC 27.8 27.2 29.4 32.4 28.4 27.5 29.7 32.7 29.3 28.0 30.1 33.0 125 SHC 27.5 22.8 23.9 18.4 28.2 23.8 25.0 19.1 29.0 25.4 26.7 20.2 kW 4.4 4.3 4.4 4.4 4.4 4.4 4.4 4.4 4.5 4.5 4.5 4.5 574B042 COOLING PERFORMANCE TABLE Evaporator Air—CFM/BF Temp (F) Outdoor Air 1225/0.11 1400/0.12 1575/0.14 Entering Condenser Evaporator Air — Ewb (F) 62 63* 67 72 62 63* 67 72 62 63* 67 72 75 TC SHC kW 85 TC SHC kW 95 TC SHC kW 105 TC SHC kW 115 TC SHC kW 125 TC SHC kW See Legend and Notes on page 15. —14— PERFORMANCE DATA (cont) STANDARD INDOOR ECM MOTOR COOLING CAPACITIES (cont) 574B048 COOLING PERFORMANCE TABLE Temp (F) Outdoor Air Ent...
