资料简介： Cycle performance study on R32/R125/R161 as analternative refrigerant to R407C
Abstract
This paper presents the new ternary non-azeotropic mixture of R32/R125/R161 as an alternative refrigerant to R407C. The physical properties of the ternary mixture are similar to those of R407C, and it is environmental friendly, that is, it has zero ozone-depletion potentials (ODP) and lower global warming potentials (GWP) than R407C. Theoretical cycle performances of R32/R125/R161 and R407C are calculated and analyzed ?rstly. Based on the theoretical study, experimental tests are performed on a vapor-compression refrigeration system with a rotor compressor which was originally designed for R407C (without any modi?cations to system components for R407C). Experimental results under different working conditions indicate that the pressure ratio and power consumption of the new refrigerant are lower than those of R407C, and its refrigerating capacity and coeffcient of performance (COP) are superior to those ofR407C, respectively, and its discharge temperature is slightly higher than that of R407C. Therefore, the new refrigerant R32/R125/R161could be considered as a promising refrigerant to R407C.2007 Elsevier Ltd. All rights reserved.Keywords: Mixture; Cycle performance; R32/R125/R161; R407C
对R407C 的一种替换制冷剂R32/R125/R161的周期性能研究摘要：
本文研究R407C一种替代制冷剂：R32/R125/R161组成的新非共沸混合物。新三元混合物的物理特性和R407C类似，但它对环境影响较小：臭氧层耗能值(ODP)为零，温室效应潜能值(GWP)比R407C低。本文的实验在以R407C为制冷剂的压缩机内进行的（没有对压缩机各元件做任何改变），在实验中，对R32/R125/R161和R407C理论循环性能进行计算和研究。实验结果表明：在不同的工作环境下，新制冷剂的压缩比和耗能值低于R407C，但它的排气温度高于R407C，总体来讲它的制冷性能更加优越。所以，新制冷剂R32/R125/R161 可以作为R407C的一种替代选择。关键字：混合物；循环性能； R32/R125/R161； R407C
