■Heating capacity correction diagram (relative humidity correction diagram)
The heating capacity changes depending on the relative humidity.
When the relative humidity is other than RH=85%, correct the capacity based on the following graph.
[Example] When the outdoor air temperature = 0°C and relative humidity RH=50%
Heating capacity in performance diagram × 0.926 <Correction value> = Heating capacity after correction
