为了探究机械泵驱动分离式热管对空调系统冷量回收和除湿能力的影响,搭建了四组该热管系统进行实验,其循环工质为R134a。在入口空气干球温度28.5℃、相对湿度60%的条件下,当运行热管由0增加到4组时,系统的机器露点由11.7℃降到8.2℃,供风温度由11.7℃升到24.1℃,系统的除湿能力增加了29.5%。指数δ(热管系统回收的冷量与制冷机蒸发器的制冷量之比)达到66.0%。研究结果表明,机械泵驱动分离式热管可以显著提高空调系统除湿能力,降低系统能耗。
In order to explore the impact of the mechanical pump-driven split heat pipe on the cold recovery and dehumidification capacity of the air conditioning system, four sets of the heat pipe system were set up for experiments, and the circulating working fluid was R134a. When the inlet air dry-bulb temperature is 28.5 ℃ and relative humidity is 60%, the system dew point drops from 11.7 ℃ to 8.2 ℃ and the air supply temperature rises from 11.7 ℃ to 24.1 ℃ when the operating heat pipe increases from 0 to 4. , The system’s dehumidification capacity increased by 29.5%. The index δ (the ratio of the heat recovered by the heat pipe system to the refrigeration capacity of the evaporator of the refrigerator) reached 66.0%. The results show that the mechanical pump driven separate heat pipe can significantly improve the air conditioning system dehumidification capacity and reduce system energy consumption.
