Studies on dispersion of refrigerant composition for multi-air conditioners with non-azeotropic refrigerant mixture

摘要

Amendments to the Montreal Protocol made in Copenhagen in November of 1992 decree that HCFCrefrigerants such as HCFC-22, which are at present widely used in air conditioning and refrigerationsystems, are to be regulated beginning in 1996 and phased out by 2020. Predictions regarding steadystate performance technology and the cycle composition shifts of multi-air conditioners with non-azeotropic refrigerant mixtures are presented in this paper. It is predicted that the ratio of low boilingpoint refrigerants in the composition of indoor units not in operation will increase. Therefore, the ratioof the low boiling point refrigerants in cycle refrigerants will decreases along with the increase inindoor units not in operation. The results of our predictions indicate that cycle refrigerants will benonflammable.
