摘　　要：为了在干/湿球温差较大的地区实现气泵热管复合空调的高能效运行,在系统冷凝侧增加蒸发冷凝(喷淋/喷雾)装置,使系统在夏季高温季节能够延长自然冷源的利用时长,降低机组能耗。通过焓差实验室将室内回风温度分别设置为24、30、35℃等3种工况,在每一室内工况下将室外温度在-10~45℃温度范围内每隔5℃进行测试,并记录100%负荷以及75%负荷的制冷量、消耗功率。结果表明:蒸发冷凝技术降低了冷凝温度,拓宽了气泵热管模式的运行温区,降低了运行能耗;系统蒸发温度随着室内回风工况的升高而增加,100%负荷率下复合空调样机在室内24、30、35℃工况下分别实现平均PUE≤1.33、1.28、1.25,75%负荷率下,复合空调样机可实现平均PUE≤1.3、1.27、1.24,节能效益良好。In order to realize the high-energy-efficiency operation of the gas pump heat pipe composite air conditioner in areas with large dry/wet bulb temperature differences,an evaporative condensation(spray/spray)device was added on the condensation side of the system,so that the system can extend the utilization time of natural cooling sources in summer high temperature seasons,and reduce unit energy consumption.In the enthalpy difference laboratory,the indoor return air temperature was set to three working conditions of 24,30,35℃,and the outdoor temperature was adjusted every 5℃from-10℃to 45℃under each indoor working condition,and the cooling capacity,power consumption and other data of 100%load and 75%load were recorded.The results show that the evaporative condensation technology can reduce the condensing temperature,broaden the operating temperature range of the gas pump heat pipe mode,and reduce the operating energy consumption;the evaporation temperature of the system increases with the increase of the indoor return air condition.Under the indoor conditions of 24,30,35℃,average PUE≤1.33,1.28,1.25 were achieved respectively.Under 75%load rate,the composite air conditioner prototype can achieve average PUE≤1.3,1.27,1.24,which has good energy-saving benefits.
