【摘要】 对不同浓度的新型HFC-161混合制冷剂进行了热力学性能和理论循环性能预测,筛选出一种HFC-161混合物(HFC-161/125/32),其热力学性能和循环性能与R410A相近,且环境性能良好,ODP为零,GWP值小于R410A,推荐作为R410A的一种直接替代制冷剂。变工况循环性能分析表明,新型混合制冷剂M3的循环压力、排气温度、单位容积制冷量和单位容积耗功量均比R410A有所减小。其中,冷凝压力、单位容积制冷量和单位容积耗功量的减少比较明显,而循环COP则比R410A有所增加,M3可用于R410A制冷系统的直接冲灌替代。更多还原

【Abstract】 Thermodynamic properties and performance of theoretical cycle of R161 mixtures with different compositions have been predicted. A HFC-161 mixture(HFC-161/125/32) has been selected as an alternative of R410A. It has a similar performance of R410A with better environmental character. Its ODP is 0 and CWP is less than that of R410A. The results of theoretical cycle under different working conditions show that the pressures, discharge temperature, unit volume refrigerating capacity and unit volume work consumption are all less than those of R410A while the COP is greater than R410A. It seems to be a good drop- in substitute of R410A.更多还原
