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:
LDB ■ FDB — Sensible Heat Capacity ^Btuh)
