Notes:

1. Sensible heat capacities shown are based on 80F

entering air at the evaporator.

2. Direct interpolation is permissible. Do not extrapolate.
3. To interpolate:

(a) below 80 F DB, subtract 872 Btuh per 1000 efir. for

each degree below 80 F from the listed sensible
capacity.

(b) above 80 F DB, add 872 Btuh per 1000 efra for

each degree above 80 F from the listed sensible
capacity.

4. Formula:
