An Investigation on the Utilization of R470A for Air-Conditioning Systems Towards 2025
The refrigerants with GWP > 750 will not be used in air conditioners according to the application of European Union restrictions that will become valid as of 2025. In this context, this study aims to investigate theoretically the utilization of the non-flammable and low-GWP refrigerant of R470A in the air conditioning system. In the analysis, R470A and R32 are compared for the evaporation temperatures of 5, 10, and 12°C while the condenser temperatures of 40 and 50°C. Although the COP of R470A is determined to be lower than R32 for a given situation of evaporation and condenser temperature, it can be safely used in systems requiring a higher amount of refrigerant charge due to its non-flammable property.
