摘要
目前我国多联机变频空调机组均采用全年性能系数(APF)替代IPLV作为评价指标。基于现有多联变频空调器的调节范围广的特点,指出了现有APF中对于选择性试验即低温制冷工况实测时,会出现不符合实际的情况,利用实测数据和理论分析产生的原因,水平展开,并给出了针对实测的改进建议。
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.
