NOTES
1 Ratings shown are net capacities which include a deduction for
indoor fan motor heat
2 shows nominal (rated) 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
SHC1 for any indoor dry-bulb temperatures (EDB1) shall be
calculated by the following formula.
SHC*: Correction value of SHC matched with the differential of EDB
and EDB1.
SHC*=0.02 X AFR(m
The calculation value of SHC1 = SHC + SHC*
5 Capacities are based on following conditions:
Corresponding refrigerant piping length:
Level difference:
6 Air flow rate (AFR) and Bypass factor (BF) are taburated above.
