卡诺逆循环是一种理想的制冷机循环过程,具有重要的理论指导意义。实际的制冷机最典型的就是空调,其循环工作过程可以近似地看做卡诺逆循环过程。本文借助卡诺制冷机的性能评价指标——制冷系数来分析理解空调制冷和制热过程的不同及其功率差异,理论上解释了空调制冷时较制热时省电的原因。还从理论上分析了取暖器和空调制热性能上的差异,发现产生相同的热量,空调更加省电,换言之,空调较取暖器的制热性能更好。
Carnot reverse cycle is an ideal cycle of the refrigerator, which has important theoretical significance. The actual refrigerator is the most typical air-conditioning, the cycle of work can be roughly seen as the process of reverse cycle Carnot. In this paper, with the help of the performance evaluation index of the Carnot chiller - the refrigeration coefficient to analyze and understand the difference between the cooling and heating process of air-conditioning and the power difference, theoretically explain the reasons for the power saving when the air-conditioning cooling is heating. Also from the theoretical analysis of heating and air conditioning heating performance differences, found that produce the same heat, air conditioning more power saving, in other words, air conditioning heating performance better than the heater.
