Abstract: | The chlorofluorocarbon (CFC) and hydro chlorofluorocarbon (HCFC) refrigerants are being replaced by hydro fluorocarbon (HFC) and HFC mixtures due to environmental concerns about depletion of the ozone layer and global warming. Various researchers have suggested different alternative to R-22 such as R-290, R-502, R407C, R-410A, and R-417A etc. R-22 has ozone depletion potential 0.055,which have harmful effect on ozone layer; hence R-22 is required to be phased out by year 2030 in developed countries and by year 2040 in developing countries. An air conditioning system using alternative refrigerants needs to be modified or alternatively designed due to variation in the physical properties of these alternative refrigerants with R-22.R-290 is flammable and R-502 is azeotropes refrigerant. In the present work exergy analysis along with energy analysis of vapour compression refrigeration cycle for R-22 and its alternate refrigerant R407C, R410A and R417A has been carried out by varying evapo... |
