摘要

目前空调用制冷剂

R22的主要替代物是R410A与R407C

它们的ODP值虽然为0

但是GWP值还较高

仍然会对环境造成不利的影响。将R1234ze和R152a以40:60组成一种新型混合制冷剂(用代号NCUR01表示)

并对其进行理论分析

通过分析NCUR01的环境影响指数、温度滑移特性、理论热力循环性能、热力学性质、安全性以及润滑油等因素

并与R22及其主要替代制冷剂R410A、R407C进行对比

结果显示:该混合制冷剂对环境的影响非常小

具有与R22相似的饱和压力线

而且具有较低的排气温度与较高的COP值

NCUR01的COP值比R22高约5%、比R410A高约19.6%、比R407C高约9.7%

排气温度比R22与R410A低约18℃、比R407C低约6℃

是一种性能良好的近共沸混合制冷剂

替代R22具有可行性。

Abstract

Among current air conditioning refrigerants

R410A and R407C are the main alternative refrigerants of R22. Their ODP is zero

but their GWP is relatively high

with a negative impact on the environment. For the selected mixed refrigerant composed of mass fraction of 40% of R1234ze and 60% R152a (represented by NCUR01)

its theoretical analyses according to REFOROP9.0

analyzing its environmental impact index

its temperature glide characteristics

theoretical thermodynamic cycle performance

thermodynamic properties

safety and lubricants

and other factors are carried out and compared with R22

its major alternative refrigerants R410A and R407C. The results show that the mixed refrigerant has very small impact on the environment

presents similar saturation pressure line to that of R22

and has a lower discharge temperature and a higher COP. The discharge temperature of NCUR01 is 18℃ lower than that of R22 and R410A

6℃ lower than that of R407C. COP of NCUR01 is about 5% higher than that of R22

19.6% higher than R410A

and 9.7% higher than R407C. Thus it is an excellent near-azeotropic refrigerant

a feasible alternative of R22.
