摘要

This paper presents the different characteristics of Ozone Friendly- Hydro fluorocarbon refrigerants (HFCs) group refrigerant i.e. R32 and R410A in vapour compression refrigeration system. The performance parameters were simulated with available experimental data of R22 and R410A (near azeotrope) mixture refrigerant with 1.565 'TR' (Ton of Refrigeration) capacity, by using REFPROP and cool pack simulation tool. The main objective of selecting the HFCs group refrigerant is to explore the possibility of developing new Zero ODP and very low GWP refrigerants an alternative to R22 and R410A refrigerants in Air Conditioning applications. R22 is HCFC group refrigerant with 0.05 ODP and 1700GWP and R410A with Zero ODP and 2100 GWP which are responsible for environmental impacts. World community has decided to phase-out such refrigerants. R32 is having Zero ODP and Very low GWP (650). For simulation the evaporator operating temperatures from -10℃ to +10℃ and condenser temperature from 35 ℃ to 60℃ was considered. Wit compare to R22 and R410A refrigerants, the refrigerant R32 yield better Coefficient of Performance at higher ambient temperatures.R32 is emerging in the refrigeration market because of its better energy efficiency and environmental friendly refrigerant. The atmospheric life for R22 is 15 years and for R32 is 4.9 years hence R32 has been accepted as safety group refrigerant under the class A2L ASHARE standers.
