NOTES
1. Ratings shown are net capacities which include a deduction for indoor fan motor heat
2. On the figure the mark j show the max. at standard conditions.
On the figure the mark Q show rated capacity and rated coefficient of power input.
However the max. capacity is not guaranteed, except at standard condition.
3. On the tables Q show rated capacity and rated coefficient of power input.
4. SHC is based on each EWB and EDB
SHC* = SHC correction for other dry bulb
3
SHC* = 0.02 x AFR (m /min.) x (1−BF) x (DB*−EDB)
Add SHC* to SHC.
5. Capacities are based on following conditions:
Outdoor air : 85 % RH. however, the condition on nominal capacity is 7° CDB/6° CWB (heating)
Corresponding refrigerant piping length
Level difference
6. Coefficient of power input is the percentage when the rated valve is defined as 1.00.
7. The value contains less than 5% error acording to indoor unit type.
8. Heating capacity include the drop of frost formation.
9. Air flow rate and BF are tabulated below.
