Abstract
The aim of this study was to compare and evaluate the frigorific air conditioning system using HFO-1234yf and R-134a as a refrigerant. For this aim, an experimental frigorific air conditioning system using both refrigerants was developed and refrigerated air was introduced into a refrigerated room. The performance parameters determined were the change of the air temperature in the condenser inlet and time. The performance of frigorific air conditioning system has been evaluated by applying energy analysis. Experiments were conducted for a standard frigorific air conditioning system using the R134a as a refrigerant. Airflow has been introduced to the refrigerated room for 60 min for each performance test. From the result for both refrigerant, the temperature gradient in time was comparable. The HFO-1234yf refrigerant can use the standard frigorific air conditioning system that is currently being used by the R134a refrigerant, without any changes needing to be made.
