摘　　要：本文对数码涡旋多联式空调系统制冷工况进行了实验研究,得出了启动工况下室内温度与系统耗功的变化规律、变流量工况下压缩机负载时间与制冷剂流量变化规律以及稳定运行工况下系统小时能效比、小时耗功随部分负荷率的变化规律。结果表明:数码涡旋多联式空调系统启动快速,室内设定温度降低时压缩机负载时间和制冷剂流量均有所增加,系统调节能力强,且在部分负荷时具有很好的节能特性。In this paper,the experimental study on operation performance of digital variable multi（DVM） air-conditioning system under cooling conditions was carried out.The variation trends of indoor air temperature and energy consumption of the system under start-up condition were obtained,as well as the compressor load time and refrigerant flow rate under variable refrigerant flow conditions.Meanwhile,under stable operation conditions,the relationships of hourly energy efficiency ratio and hourly energy consumption vs.part load ratio were presented.Experimental results demonstrated that DVM air-conditioning system could be operated quickly,the compressor load time and refrigerant flow rate would be increased when the setpoint of indoor air temperature was lowered.Furthermore,the adjustment capacity of this system could be improved and its energy efficiency could be enhanced under part load conditions.
