Air Handler Selection Example
Figure 1 shows a typical performance table for a heat pump
air handler. Suppose the evaporator temperature required
is 50ºF, the capacity required is 35,000 Btuh and the air
Å ow
required is 1,200 CFM. Each evaporator temperature
listed in the table shows three wet bulb temperatures. As
recommended in the table notes above, select the 67ºF
WB column. At 1,200 CFM, the model 003 capacity is 36
MBtuh, which is higher than the minimum capacity required
of 35,000 Btuh. In this example, model 003 would be the
appropriate match.
