压缩机变频调节的小型空气源热泵制热性能实验研究

Experimental study on heating performance of small air source heat pump with compressor frequency conversion

为研究压缩机变频对热泵制热性能的影响,搭建了额定4HP变频压缩机热泵系统实验装置,实验研究压缩机在不同频率下,热泵的排气温度、吸气压力、制热量、压缩机耗功率和制热COP的变化,为空气源热泵的进一步节能运行提供理论依据。

In order to prove the influence of compressor frequency conversion on the heat pump performance,the experimental device of the rated 4 HP with compressor frequency conversion heat pump system is set up in this paper.The experimental study on the change of exhaust temperature,suction pressure,heat production,compressor power consumption and heat production COP of the compressor at different frequencies was carried out,hoping to provide a theoretical basis for the further energy saving operation of the air source heat pump.
