摘要
综述在冷冻冷藏系统中制冷剂替代研究的现状。在此基础上,提出一种新的混合制冷剂(HFC-161/HFC-125/HFC-143a,15/45/40)用于替代HFC-404A,该新型制冷剂的ODP为零,GWP比HFC-404A和R507A要小,其基本热力学性能与HFC-404A相近。对新型混合制冷剂和HFC-404A的循环性能进行理论分析与比较。结果表明,新型混合制冷剂的性能要比HFC-404A优越,环境性能更好,是HFC-404A潜有力的替代制冷剂。
The research status on refrigerant substitute for the freeze and cold storage system is reviewed. Based on this, a new ternary non-azeotropic mixture of HFC-161/HFC- 125/HFC-143a（15/45/40） as a promising mixed refrigerant to HFC-404A is presented. The ODP of the new refrigerant is zero and its basic thermodynamic properties are similar to those of HFC-404A,and its GWP is much smaller than that of R507A or HFC-404A. The cycle performance between the new mixture refrigerant and HFC-404A is theoretically analyzed and compared. The results show that the cycle performance and environmental performance of the new mixture refrigerant are better than those of HFC-404A. The new mixture refrigerant may be a promising alternative refrigerant for HFC-404A.
