- Abstract
In this paper, the performance of various alternative refrigerants were compared to find the replacement for R22, the widely used hydrochlorofluorocarbon (HCFC) refrigerant in home air conditioning systems in most developing countries. This study include the environment friendly hydrofluorocarbon (HFC) refrigerants such as R-134a, R-410A, R-407C and R- 404A. A steady state thermodynamic modelling and simulation of a home air conditioner as an actual vaporcompression system was developed. The model predicted the performance of the system with the mentioned alternative refrigerants in terms of energy and exergy. Based on design conditions, operating parameters, such as coefficient of performance (COP), energy efficiency rating (EER), exergy efficiency (η11) and exergy destruction ratio (EDR) were evaluated. The results obtained showed that R-134a, R-410A, R407C, and R-404A are better substitute to replace R22, as they are more environment friendly air conditioning cooling applications.
