IISelect unit based on required cooling capacity.

Enter Cooling Capacities table at condenser entering temperature of 95°F. The 036 unit 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.

IIISelect electric heat.

The required heating capacity is 15,000 Btuh (given).

Determine the electric heat capacity in kW. 15,000 Btuh

3414 Btuh/kW

Enter the Electric Heater Packages table for 208/240, single-phase, 036 unit. The 5-kW heater at 240v most

closely satisfies the heating required. To calculate kW at 208v, multiply the heater kW by multiplication factor 0.75 found in the Wattage Multiplication Factors table.

5 kW x 0.75 = 3.75 kW

3.75 kW x 3414 Btuh/kW = 12,802.50 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, Filter Pressure Drop table, and the Accessory Electric Heat Pressure Drop table, find:

Wet coil pressure drop External static pressure Filter

Total static pressure

Enter the table for Dry Coil Air Delivery — At 0.362 in. wg external static pressure and NOM speed pin selection, the motor delivers 1235 cfm.

VSelect unit that corresponds to power source available. The Electrical Data table shows that the unit is designed to operate at 208/230-1-60.
