AB - 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.
