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