MBtuh — Btuh in thousands
NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The following formulas may be used:
sensible capacity (1000 x MBtuh)
t=t –
ldb edb
1.10 x cfm
t = Wet-bulb temperature corresponding to enthalpy of air
lwb
leaving evaporator coil (h )
lwb
total capacity (1000 x MBtuh)
h=h –
lwb ewb
4.5 x cfm
Where: h = Enthalpy of air entering evaporator coil.
ewb
3. The sensible heat capacity is based on 80 F entering dry-bulb (edb) tempera-
ture of air entering evaporator coil.
Below 80 F edb, subtract (corr factor x cfm) from the sensible heat capacity.
Above 80 F edb, add (corr factor x cfm) to the sensible heat capacity.
Correction Factor = 1.10 x (1 – BF) x (edb – 80).
