Analysis of Circulation Characteristics of Six Kinds of Sixteen Refrigerants in Refrigeration Cycle
It analyzes the circulation characteristics of refrigerants in refrigeration cycles.The effects of single condensing temperature variation on unit cooling capacity,COP,pressure ratio and compression and exhaust temperature of the system of 16 refrigerants,including inorganic compounds,HCs,CFC,HFCs,HCFC,and HFOs(R600a,R245fa,R1234yf,etc)were analyzed theoretically.The results show that HCs refrigerants,HFOs refrigerants and R245fa refrigerants in HFCs have good cycling performance in refrigeration cycles at the operating evaporation temperature of-10 degrees and condensation temperature of 30℃~50℃.It will have important research value for selecting suitable refrigerant in the future.
