热湿地区不同溶液除湿蒸发冷却系统性能研究
Performance of different liquid desiccant evaporative cooling systems in hot and humid regions
摘要：
介绍了6种常见余热驱动溶液除湿蒸发冷却系统。在热湿环境下，通过改变再生循环中余热热水入口温度，对6种型式的系统进行了分析。结果表明：综合了室内回风全热回收器和室内回风蒸发冷却器的系统的送风温湿度较适宜，新风获得冷量比其他型式多2.8%~66.7%,系统平均热力系数可高达0.916，最后在不同城市的热湿环境下对该型式的溶液除湿蒸发冷却系统进行了验证。
Abstract：
Presents six kinds of common waste heat driven liquid desiccant evaporative cooling systems. Under hot and humid environments, analyses the performances of six kinds of systems by varying the inlet temperature of waste heat water. The results show that the supply air temperature and humidity of the system with air-to-air total heat exchanger and evaporative cooler are suitable. The cooling capacity obtained by out door air is 2.8%~66.7% more than that of other systems. The average thermodynamic coefficient of the system is 0.916. The system is verified under the hot and humid environment of different cities.
