Actual cooling capacity calculation:
Actual cooling capacity=amendment coefficient of cooling capacity × nominal cooling capacity
——nominal cooling capacity could be found from the performance parameters list
——amendment coefficient of cooling capacity could be found from table above.
3.3 Amendment coefficient of heating capacity under different indoor/outdoor DB/WB
