COMPARATIVE PERFORMANCE ANALYSIS OF EXPERIMENTAL FRIGORIFIC AIR CONDITIONING SYSTEM USING R-134A AND HFO-1234YF AS A REFRIGERANT

ABSTRACT
In this study, to evaluate the comparative experimental performances, a frigorific air conditioning system using HFO1234yf and R134a was developed and refrigerated air was introduced into a conditioned room. The experiment was carried out at different condenser inlet temperatures and using the refrigerants at different charges, 1250 g, 1500g, and 1750g. Experiments were conducted for a standard frigorific air conditioning system using the HFO1234yf and R-134a system. Air flow was introduced to the conditioned room for 60 minutes for each performance test. The results revealed that the temperature gradient in time was comparable for both refrigerants. The results of this investigation propose utilising HFO1234yf as a replacement for the currently favoured R134a in a frigorific air conditioning system.
