摘要
介绍R32,R22和R407C以及R410A四种制冷剂的流动特性和热力学特性,并对采用这4种制冷剂的空气源热泵热水器进行理论循环分析。从计算结果可以看出,与采用其他3种制冷剂的系统对比,采用R32制冷剂的系统具有较低的压缩比,较高的理论COP以及容积制热量;在当前阶段,R32是用于空气源热泵热水器的一种较好的制冷剂。
Introduces the thermodynamic and flow properties of R32,R22,R407C and R410A,and analyzes the theoretical cycle performance that employs these four kinds of refrigerants for the air source heat pump water heater.Compared with the other three kinds of refrigerant,the R32 system has the characteristics of lower compressor ratio,higher theoretical COP and volume heating capacity.It shows that R32 is a good refrigerant for air source heat pump water heater system.
