SELECTION PROCEDURE I DETERMINE COOLING AND HEATING REQUIRE- MENTS AT DESIGN CONDITIONS. Given: Required Cooling Capacity (TC)... 28,000 Btuh Sensible Heat Capacity (SHC)... 20,500 Btuh Required Heating Capacity...28,550 Btuh Outdoor Entering-Air Temperature...95F Outdoor-Air Winter Design Temperature...20F Indoor-Air Winter Design Temperature...70F Indoor Entering-Air Temperature...80Fedb, 67 F ewb Indoor-Air Quantity...1125cfm External Static Pressure...0.40 in. wg Electrical Characteristics (V-Ph-Hz)... 230-1-60 edb entering dry bulb ewb entering wet bulb II SELECT BASED ON REQUIRED COOLING CAPACITY. Enter Cooling Capacities table at condenser entering temperature of 95 F, indoor air entering at 1125 cfm and 67 F ewb (entering wet bulb). The 655A030 unit will provide a total cooling capacity of 29,300 Btuh and a sensible heat capacity of 22,100 Btuh. For indoor-air temperature other than 80 F edb (entering dry bulb), calculate sensible heat capacity correction, as required, using the formula found in Note 3 following the cooling capacities tables. NOTE: Unit ratings are net capacities. III SELECT ELECTRIC HEAT. Enter the Heating Capacities table, page 13 at 1125 cfm. At 70 F return indoor air and 20 F air entering outdoor coil, the integrated heating capacity is 14,900 Btuh. (Select integrated heating capacity value since deductions for outdoor-coil frost and defrosting have already been made. No correction is required.) The required heating capacity is 28,550 Btuh. Therefore, 13,650 Btuh (28,550 14,900) additional electric heat is required. Determine additional electric heat capacity in kw. 13,650 Btuh = 4.0 kw of heat required 3414 Btuh/kW Enter the Electric Heater Packages table on page 19 for 208/240 v, single-phase, 655A030 unit. The 5-kW heater at 240 v most closely satisfies the heating required. To calculate kw at 230 v, multiply the heater kw by multiplication factor 0.92 found in the Wattage Multiplication Factors table on page 21. 5 kw x.92 = 4.6 kw 4.6 x 3414 = 15,704 Btuh To calculate kw at 208 v, see note below Electric Heater Packages table on page 19. Total unit heating capacity is 30,604 Btuh (14,900 + 15,704). IV DETERMINE FAN SPEED AND POWER REQUIRE- MENTS AT DESIGN CONDITIONS. Before entering the air delivery tables, calculate the total static pressure required.
