7. Capacity Correction Factor
7.2 Defrosting Correction Factor for Heating Operation
The capacity table does not consider reduction in capacity when frost has accumulated or during defrosting.
The capacity values considered these factors, in other words the integrated heating capacity values, can be
obtained as follows:
[ Formula ]
• Integrated Heating capacity = A
• Value given in table of capacity characteristics = B
• Integrated correction factor for frost accumulation = C
• A=B x C
[ Correction factor for finding integrated Heating capacity ]

Capacity
Please note that there will be temporary reduction in capacity when snow piles up on the outside surface
of the heat exchanger. Of course, it will be different in degree depending on a number of other factors, for
example, the outdoor temperature(°CDB), the relative humidity(RH) and the frosting amount.
