NOTES
1. Ratings shown are net capacities.
Influence of fan motor heat is included.
2. Shows nominal capacities
3. SHC is based on each EWB and EDB
SHC* = SHC correction for other dry bulb
3
SHC* = 0.29 x 60 x AFR (m /min.) x (1−BF) x (DB*−EDB)/860
Add SHC* to SHC if SHC > TC, then TC equal SHC
4. Direct interpolation is permissible.
Do not extrapolate.
5. Capacities are based on following conditions:
Corresponding refrigerant piping length
Level difference
6. Air flow rate and BF are tabulated below.
