Summary

The effect factors that influence the leakage characteristics of HFC-161/125/32, a new alternative refrigerant for HCFC-22, were discussed. Corresponding leakage models were built and the mass ratio variations of each component under gas phase isothcnnal leakage and gas phase isobaric leakage cases were studied. Based on the obtained mass ratio variation data, cycle perfonnance variations of the mixture were deduced. As the mass ratio variations under gas phase isobaric leakage cases are sma ll er than that of isothennal, the analysis of related perfomlances were studied under gas phase isothennal leakage conditions. Based on the analysis results, it is indicated that the influence of maximum practical leakage rate on refrigeration cycle perfonnance is not higher than 3%. The corresponding cycle perfonnance variation is not higher than 5% after refrigerant recharge.
