Comfort-Aire HTS Series Split System,Two Stage, 2-5 Tons - Manual (Page 7)

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 airfl 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.
