SELECTION PROCEDURE
Determine cooling and heating requirements at design
conditions:
Given:
REQUIRED COOLING CAPACITY (TC)
34,500 BTUH
. . . . . .
SENSIBLE HEAT CAPACITY (SHC)
24,000 BTUH
. . . . . . . . .
REQUIRED HEATING CAPACITY (SHC)
15,000 BTUH

Select unit based on required cooling capacity
Enter Net Cooling Capacities table at condenser entering
temperature of 95
°
F (35
°
C). The 036 unit at 1200 cfm and 67
°
F
(19.4
°
C) ewb (entering wet bulb) will provide a total capacity of
34,600 Btuh and a SHC of 24,220 Btuh. Calculate SHC correction,
if required, using Note 4 under Cooling Capacities tables.
Select electric heat
The required heating capacity is 15,000 Btuh.
Determine additional electric heat capacity in kW.
15,000 Btuh
3414 Btuh/kW
= 4.4kW of heat required
Enter the Electric Heater table on page 5 for 208/230v,
single--phase unit. The 5--kW heater at 240v most closely satisfies
the heating required. To calculate kW at 230v, multiply the heater
kW by multiplication factor 0.92 found in the Multiplication
Factors table on page 17.
5 kW x 0.92 = 4.6 kW
4.6 kW x 3414 Btuh/kW = 15,704 Btuh (Total unit heating
capacity)
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.
