摘　　要：以数码涡旋多联式空调系统为研究对象,通过研究其在夏热冬冷地区制冷运行时部分负荷条件下的运行特性,分析小时能效比、小时耗功随部分负荷率、室外温度的变化规律。研究结果表明:不论室内机开启台数和室外温度如何变化,小时耗功和小时能效比在室内外工况一定时随部分负荷率分别呈下凹和上凸曲线分布,数码涡旋多联式空调机组在部分负荷时具有很好的节能特性;室内机全开、部分负荷率在0.52～1.08范围内,室外温度较高时,小时耗功随部分负荷率增加而增加的趋势更显著,不利于系统节能运行,而室外温度较低时,小时能效比随部分负荷率增加而增加的趋势更显著,有利于系统节能运行;室内外温度一定、部分负荷率相同时,小时耗功随室内机开启台数的增加而减小,小时能效比随室内机开启台数的增加而增加。The operating characteristics for partial load in summer of DVM air-conditioning system in hot stnnmer and cold winter zone was studied by experiments. Hourly energy efficiency ratio and hourly work under different partial load value and outdoor air temperature were analyzed. Experimental results show that hourly work and hourly energy efficiency ratio under different partial load value present below-concave and up-protruding distribution. DVM air-conditioning system shows good energy-saving characteristic in partial load conditions. Higher outdoor air temperature presents more evident influence on hourly work and less evident influence on hourly energy efficiency ratio when indoor units are all ＂on＂ and partial load ratio is in the range of 0.52 to 1.08, which is not helpful for energy-saving. Hourly work is decreased and hourly energy efficiency ratio is increased when the number of ＂on＂ indoor units is increased and indoor air temperature, outdoor air temperature, and partial load value are constant.
