Analysis on APF Calculation Problem Caused by the Optional Method to Obtaining Performance Parameters of Low-temperature Intermediate Refrigeration Condition in GB 21455—2019

To evaluate the APF of an air conditioner according to GB 21455—2019, the performance parameters of low-temperature intermediate cooling conditions can be measured or converted, resulting in two different APF values using these two different methods in the same air conditioner. Considering the diffe...
