开发 HFC134a 的主要目的在于用其替代会损害臭氧层的 CFC12制冷剂。因此,比较这两种制冷剂是有一定的意义。这里所列的比较结果为采用开启式斜盘板压缩机进行试验所得。热力比较在两种制冷剂的饱和曲线中可以看出,在固定的吸排气温度间的制冷循环中,工作介质为 HFC134a 的压力比总比 CFC12的更高些。就压缩机容积效率而言,这是个 The main purpose of developing HFC134a is to use it to replace CFC12 refrigerants that can damage the ozone layer. Therefore, comparing the two refrigerants is of some significance. The results of the comparisons listed here are based on tests carried out with an open swash plate compressor. Comparison of heat capacity It can be seen in the saturation curves of the two refrigerants that the pressure of the working medium HFC134a is always higher than that of CFC12 in the refrigeration cycle with a fixed suction-exhaust temperature. In terms of compressor volume efficiency, this is one
