Abstract

In domestic air conditioning system the most widely used refrigerant is R22 has a high Global Warming Potential (GWP) of 1700 and a ozone depletion potential (ODP) of 0.05. Hence a new solution for this refrigerant is to be identified. R152a is identified as an alternative to R12 and R22 refrigerants. In this paper an experimental investigation was made to reduce the usage of R22 with the Hydrocarbon Refrigerant mixtures (HCM) of R22 and R152a refrigerants in the ratio of 30:70, 50:50, and 70:30 by mass. Experiments were conducted by continuous running tests under an ambient temperature of 32°C. The overall performance of the system proved that the HCM could be a long term substitute for R22 (chlorodifluoromethane).
