摘要
蒸汽压缩式热泵在蒸发温度低时排气温度很高,严重影响机组运行的稳定性,特别是R32工质。提出利用自然冷源过冷的方法改善其低温制热性能,并搭建了实验台。对以R32为工质的蒸气压缩式热泵进行了实验,研究热泵在过冷及普通工况下,排气温度、制热量、制热COP等参数的变化规律。
The compression heat pump has high exhaust temperature when evaporation temperature is low,which seriously affects the stability of the operation of the unit,especially the R32 engineering quality.This paper presented a method to improve the thermal performance of low temperature and established the experimental table.In this paper,the compression heat pump refrigerant is R32.The heat pump was studied under sub-cooling and normal conditions,exhaust temperature,heat production,the change rule of the parameters such as heat COP.
