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 50[Formula: see text]Hz 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 1200[Formula: see text]g 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.

R1234yf替代R134a在空调系统中的试验性能分析

在这项工作中，R1234yf作为R134a的替代方案在空调系统中进行了测试。系统在30、35、40、45和50[公式:见原文]赫兹蒸发器风扇频率下进行测试，以在35°C的固定温度下冷却进入蒸发器段的空气。每种制冷剂分别充注600g、700g、800g、1000 g和1200 g[公式见文]。装药质量为800克时，两种制冷剂的性能最佳。此外，R1234yf具有更高的COP、火用效率、第二定律效率和更低的压缩机功耗。两种制冷剂在85°C的压缩机排气温度适中范围内工作。
