1-7. Capacity Correction Graph According to Temperature Condition
Capacity characteristics
(The corrected capacity for specific temperature conditions can be found from the graphs below.)
<Cooling>
<Heating>
16HP
10HP
* The heating capacity when frost/defrost operation is considered is calculated by multiplying the heating capacity found from
the capacity graph by the correction coefficient from the table above.
