China’s inverter air conditioner efficiency standard (GB21455—2013) adopts a single set of annual performance factor (APF) values to evaluate inverter heat-pump air conditioner charged with different types of refrigerants. Obviously
neglecting the refrigerant classification is a flaw in the standard. Thus
we obtained two types of running-time curves from meteorological statistics and standard data. Furthermore
on the basis of these curves
the APF of several inverter air conditioner with different refrigerants were analyzed in terms of the same environmental impact (the total equivalent warming impact (TEWI) was chosen). The results show that the APF values of the R290 equipment were relatively lower than those of R22 and R410A under the same environmental impact. According to the standard data results (air conditioner with 2 HP cooling-capacity)
the APF differences between these refrigerants were up to 0.57 and 0.59
respectively. Finally
a refrigerant-classification evaluation in terms of the energy efficiency standards was performed. In addition to the indirect environmental influence on the equipment energy efficiency
the direct effect of refrigerants should also be considered.
