Toshiba HFC R-410A manual Heating capacity calculation method

Heating capacity calculation method:

Required heating capacity = heating capacity x factor (, , , , *1, *2) kW

Indoor air dry bulb temperature vs. capacity correction value

Capacity correction value

Indoor air dry bulb temperature (°C)

Outdoor air wet bulb temperature vs. capacity correction value

Capacity correction value

Outdoor air wet bulb temperature (°C)

Air flow variation ratio of indoor unit vs. capacity correction (for ducted units only)

Capacity correction value

Air flow variation ratio (%)

*1 Outdoor unit capacity correction factor when total capacity of the indoor units is not equal to the outdoor unit capacity. *2 Refer to the capacity correction for frosting on the outdoor heat exchanger section on page 24.
