Notes:
1. Sensible heat capacities shown are based on 80 F entering air at the evaporator.
2. Direct interpolation is permissible. Do not extrapolate.
3. To interpolate:
(a) below 80 F DB, subtract 800 Btuh per 1000 cfm
for each degree below 80 F from the listed sensible capacity.
(b) above 80 F DB, add 800 Btuh per 1000 cfm
for each degree above 80 F from the listed sensible capacity.
4. Formula:
LDB = EDB -
Sensible Heat Capacity (Btuh)
1.08 X cfm
Total Capacity (Btuh)
4.5 X cfm
where h = Enthalpy (Btu/lb)
Lh - Eh -
