Review and Suggestions on the Accuracy of Low-Temperature Operation Test(Cooling)in the APF Energy Efficiency Test of Frequency-Conversional Multi-Connected Air-Conditioning System
At present,the annual coefficient of performance(APF)is used instead of IPLV as the evaluation index of multi-online inverter air conditioning units in China.Based on the characteristics of the wide adjustment range of the existing multi-inverter air conditioner,it is pointed out that the existing APF will not conform to the actual situation when the selective test,that is,the low-temperature refrigeration condition is measured,and the reasons for the measured data and theoretical analysis are used to expand horizontally,and the improvement suggestions for the actual measurement are given.
