EXPERIMENTAL PERFORMANCE OF AIR CONDITIONER USING REFRIGERANT R410 AS ALTERNATIVE FOR R22

Abstract

Air conditioner is becoming necessary in India as the temperature during normal days and it is become necessity not luxury thing.
Most of refrigerants used in vapor Compression system were Chlorofluorocarbon (CFCs) and Hydro Chlorofluorocarbon (HCFCs)
which contains chlorine and if any leakage in the system, these gases will go up and reach stratosphere. The chlorine atoms in the
gases will act as a catalyst to destroy ozone layer and cause ozone depletion which causes health hazards, global warming, melting
of polar ice caps and drought. The refrigerant R22 widely used in the air conditioners is a major Contributor of
Chlorofluorocarbons (CFCs) which cause irreparable loss to the ozone layer and has to be replaced.R22 has higher ODP and GWP
which is negative point of this refrigerant.R-22 has to replace due to Montreal Protocol and Kyoto protocol there for we have to
think about alternative refrigerant and scanning through literature revels that some of the alternative need major change in main
component of air conditioner and R-290 could be used as retrofitted refrigerant or some minor change in same system. This paper
presents the experimental performance analysis of a window air conditioner using two refrigerants R22 and R410A.The effect of
the different parameters of performance analysis (refrigeration capacity, COP, compressor power ,pressure ratio ) were
investigated for various evaporating temperature and ambient temperature. .The result shows that refrigerant R22 is better than
R410A in case of COP, refrigeration capacity but for pressure ratio and compressor power R410A shows better performance than
R22.Since R22 refrigerant has better performance than also this refrigerant is replaced by the end of 2015.
