[Chart 4]* Correction of outdoor unit diversity
* Coefficient to use for the correction of the outdoor unit capacity when the total capacity of the indoor units are not
equal to the outdoor unit capacity.
2-3-1-3. Capacity correction in case of frost on the outdoor heat exchanger when in
heating
Correct the heating capacity when frost can be found on the outdoor heat exchanger.
Heating capacity =Capacity after correction of outdoor unit x Correction value of capacity resulted from
frost (Capacity after correction of outdoor unit: Heating capacity calculated in the
above item 2.)
[Chart 5] Capacity correction in case of frost on the outdoor heat exchanger
