混合工质变浓度空气源热泵系统的研究

STUDY OF AN AIR SOURCE HEAT PUMP WITH ALTERING CONCENTRATION OF MIXTURE REFRIGERANT

本文分析了不同浓度混合工质R32／R134a和纯质R22理论循环性能,应用新型变浓度实验热泵装置测定了混合工质R32／R134a的变浓度循环特性,并与纯质R22进行了比较。结果表明,混合工质R32／R134a具有较好的容量调节特性。

Theoretical cycle performances of mixture refrigerant R32/R134a and pure R22 are analyzed. The experimental study on a novel air source heat pump system with altering concentration of mixture refrigerant is carried out by using pure R22 and mixture R32/R134a respectively. By comparison with using pure R22, the mixture refrigerant R32/R134a has better capacity adjustment performances.
