SYMBOLS
AFR:
Air flow rate
(m
3
/min)
BF:
Bypass factor
EWB:
Entering wet bulb temp.
(°CWB)
EDB:
Entering dry bulb temp.
(°CDB)
TC:
Total capacity
(kW)
SHC:
Sensible heating capacity
(kW)
PI:
Power input
(kW)
NOTES
1. Ratings shown are net capacities which include a deduction for indoor fan
motor heat
2.
Shows nominal cooling capacities and power input
3. TC, PI and SHC must be calculated by interpolation using the figures in the
above tables. (Figures out of the tables should not be used for calculation.)
4. SHC is based on each EWB and EDB
SHC* = SHC correction for other dry bulb
SHC* = 0.02 x AFR (m
3
/min) x (1-BF) x (DB-EDB)
Add SHC* to SHC.
5. Capacities are based on the following conditions:
Corresponding refrigerant piping length:
7.5 m
Level difference:
0 m
6. Air flow rate (AFR) and Bypass factor (BF) are taburated above.
