COMPENSATION COEFFICIENT OF FROSTING / 5-2.
DEFROSTING
(HEATING OPERATION)
To take the effects of accumulated frost and defrosting operation on heating capacity into
consideration, the capacity of outdoor units should be corrected by compensation coefficient
shown in the table below.
Actual heating capacity = The value of capacity table x Capacity change rate by frosting
