摘要

提出一种新型制冷剂HFC-161/125/143a（质量百分比10/45/45）用于替代制冷剂R502。新制冷剂环境性能良好，ODP值为0，GWP值为3466，GWP值小于R502及其常用替代制冷剂R404A和R507。采用Refprop软件计算了HFC-161混合物的基本热物理性质，以及低温工况和变工况下的理论循环性能，并与制冷剂R502、R404A、R507的相关数据进行对比。结果表明：新制冷剂的运行压力、压比、COP值、单位容积制冷量与R502相当，温度滑移小于R502常用替代物R404A，是一种性能优良的制冷剂R502的替代物。

Abstract

A ternary HFC-161 mixture (HFC-161/125/143a with mass ratio 10/45/45) was proposed as an alternative refrigerant to R502. Theoretical results indicated that it is an environmentally friendly refrigerant with zero ODP (ozone depletion potential) and a GWP (global warming potential) value of 3466

which is lower than that of R502

R404A and R507. The thermophysical properties and theoretical cycle performance of HFC-161 mixture under low temperature working conditions and varying working conditions were calculated and compared with R502

R404A and R507 by software Refprop. The calculation results indicated that the operating pressure

pressure ratio

COP and cooling capacity per unit volume of HFC-161 mixture are equivalent to those of R502

and its temperature glide is smaller than that of R404A. Therefore

HFC-161 mixture can be used as a potential alternative refrigerant to R502.
