摘　　要：针对家用空调器夏季运行室外热环境差的问题,提出在其室外机增设喷雾加湿装置以降低冷凝温度进而达到提高空调器性能和制冷量的目的。本文对增设喷雾降温系统地空调器进行了试验研究,分析了增设喷雾降温系统对空调器冷凝器出口空气温度和制冷系统性能的影响。实测研究发现,增设喷雾加湿系统后,冷凝器出口制冷剂压力有所降低,制冷系统性能系数EER可提高2%~7%,效果显著。In view of the poor thermal environment of the domestic air conditioner in summer, a kind of air conditioner with additional spray cooling system for outdoor unit are presented to reduce the condensing temperature and improve the performance and the cooling capacity of the air conditioner.An experimental study was carried out on the air conditioner with the spray cooling system, and the effects of the spray cooling system on the condenser’ s outlet air temperature and the performance of the refrigeration system were analyzed. The experimental study found that the condensing pressure will be reduced and Energy Efficiency Ratio（EER） of the refrigeration system can be increased by 2%~7% by adding the spray cooling system.
