Özet
In this study, R404A and R452A refrigerants used in refrigeration systems were compared experimentally. The energy performance of the system was investigated for widely used evaporation temperatures (−5, 0, +5 °C) and condenser temperatures (25, 35, 45 °C). It was seen that COP was higher but power consumption of system was lower using R452A as a substitute for R404A. When R452A was used, COP was improved about by 3% to 8% compared to R404A. Furthermore, cooling capacity decreased about by 2% for condenser temperatures of 25 and 35 °C while it increased at condenser temperature of 45 °C. Power consumption of system was also reduced nearly by 5%. Mass flow rate of refrigerant was lower when the system was operated with R452A. In the middle term, R452A could be a suitable alternative refrigerant for commercial refrigeration applications due to its low GWP value and better energy performance compared to R404A.
