摘　　要：移动空调依靠其灵活度高、局部降温能力强的优点,具有广阔的市场前景。为解决其在高湿环境下水满停机的问题,在移动空调冷凝器底部安置了打水轮。研究了打水轮位置在高湿工况下对移动空调整体性能的影响。结果发现:打水轮的安装位置对移动空调的性能有较大的影响,在四种不同位置的打水轮中,越能够将冷凝水打入冷凝器高温区域的打水轮效果越好,移动空调EER越高,冷凝水排除能力最强;随着打水轮的打水效果增强,移动空调的蒸发压力和冷凝压力都随之下降,而制冷量增加。由于其中冷凝压力下降幅度更剧烈,移动空调输入功率减少;同时随着室内空气相对湿度升高,移动空调显热比降低。Portable air conditioners(PACs) hold significant market potential due to their high flexibility and exceptional localized cooling capabilities.To address the issue of water shutdown in high-humidity environments,water-wheels can be installed at the bottom of the condenser of the PAC.Investigated the impact of different water-wheel positions on the performance of PAC under high-humidity environments.The results showed that the position of the water wheel had a great influence on the performance of the PAC.Among the four water wheels at different po sitions,the better the effect of the water wheel that could drive condensate into the high temperature area of the condenser,the higher the PAC's EER,the strongest condensate removal ability.With the enhancement of the water splash effect of the water wheel,the evaporation pressure and condensation pressure of the PAC both decreased and the cooling capacity increased.Because the condensation pressure dropped more significantly than evaporation pressure,the input power got a decrease.What's more,the higher the relative humidity of indoor air,the lower the sensible heat ratio of the PAC.
