6-3. Correction at frost and defrost
Due to frost at the outdoor heat exchanger and the automatic defrost operation, the heating capacity of the outdoor unit can be
calculated by multiplying the correction factor shown in the table below.
Table of correction factor at frost and defrost
* The correction factors in the table above are used for a full-load and above.
Use the formula below to calculate the correction factor to use for a partial load.
Correction factor for partial load : K
Correction factor for a full load and above : K
0
Partial load factor : A
K = 1 - ( 1 - K
