Abstract
In this work, R1234yf is tested in an air-conditioning system as a proposed alternative to R134a. The system is tested at 30, 35, 40, 45 and 50Hz evaporator fan frequency to cool the air entering into the evaporator section at a fixed temperature of 35°C. The system is charged with 600, 700, 800, 1000 and 1200g of each refrigerant. The charge mass of 800 grams gives the best performance for both refrigerants. Also, R1234yf has higher COP, exergetic efficiency, second law efficiency, and lower compressor power consumption. Both refrigerants operate at a moderate range of compressor discharge temperature of 85°C.
