机械泵驱动分离式热管应用于空调冷量回收

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。

Mechanically Pump-Driven Separate Heat Pipe Employed in Air Conditioning System for Cooling Energy Recovery

To experimentally investigate the cooling energy recovering capacity of mechanically pump-driven separate heat pipe (MPSHP) in the air conditioning system, four MDSHPs were constructed and filled into R134a as working fluid. When the MPSHP increased from 0 to 4 at the constant inlet air state of 28.5 ℃ and 60% relative humidity, the apparatus dew point fell from 11.7 ℃ to 8.2 ℃, and the air -supply temperature rose from 11.7 ℃ to 24.1 ℃ , while dehumidifying capacity of the system has ultimately increased by 29.5%. The index δ (ratio between the cooling energy saved by MPSHPs and the cooling capacity of the air conditioner’s evaporator) is 66.0%. The study indicates that the air conditioning system can significantly reduce its energy consumption and improve its dehumidifying capacity when MPSHPs are employed in the air-conditioning process.
