/min)
BF: Bypass factor
EWB: Entering wet bulb temp. (°CWB)
EDB: Entering dry bulb temp. (°CDB)
TC: Total cooling capacity (kW)
SHC: Sensible heating capacity (kW)
PI: Power input (kW)
(comp.+outdoor fan motor)
CPI: Coefficient of power input. (-)
Caution:
TC and SHC are shown by kW
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. SHC is based on each EWB and EDB
SHC* = SHC correction for other dry bulb
SHC* = 0.02 x AFR (m

EDB)
Add SHC* to SHC.
4. 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
: 5.0 m
Level difference : 0 m
5. Coefficient of power input is the percentage when the rated valve is defined as 1.00.
6. The value contains less than 5% error acording to indoor unit type.
7. Air flow rate and BF are tabulated below.
