BF — Bypass Factor
Ewb — Entering Wet-Bulb
kW — Total Unit Power Input
SHC — Sensible Heat Capacity (1000 Btuh)
TC — Cooling Capacity (1000 Btuh)
ECM — Electronic Computated Motor
* — TVA Conditions (75°F Entering Dry Bulb)
NOTES:
1. Ratings are net; they do account for the effects
of the evaporator-fan motor power and heat.
2. Direct interpolation is permissible. Do not extrapolate.
3. The following formulas may be used:
4. The SHC is based on 80°F Edb (Entering dry bulb) air temperature
through Evaporator coil. Below 80°F Edb, subtract (Correction Factor x
CFM) from SHC. Above 80°F Edb, add (Correction Factor x CFM) to
SHC. Correction Factor = 1.10 x (1 – BF) x (Edb – 8)
