(-)Caution:TC and SHC are shown by kWRated pointHeating capacity (kW)Coefficient of power input. (-)NOTES1. Ratings shown are net capacities which include a deduction for indoor fan motor heat2. 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 EDBSHC* = SHC correction for other dry bulbSHC* = 0.02 x AFR (m3/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 : 7.5 mLevel difference : 0 m6. 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.(Pair)FBQ140AFR(BF)35(0.14)10.
