CO_2制冷剂在汽车空调中的应用及冬季供暖节能方法探讨

A Analysis on Refrigeration for Automobile and Its Development Vistas

随着对环境问题的关注,CO2以其优良的热物性,成为制冷剂中具有良好发展前景的天然工质。本文通过介绍CO2制冷剂组成的热泵系统采用跨临界循环的方式为汽车冬季供暖的分析,讨论此种方式的优缺点及改进方法。此外,还对汽车空调冬季供暖节能方法进行了可行性探讨。

With the increasingly great attention to the environment, CO2 has been regarded as a natural medium for refrigeration with its excellent thermal and physical character and good development foreground. The article introduces a heat pump system in composed of CO2 refrigeration medium. By means of circular style with span critical for automobile, it provides heat in winter. And also this paper analysis its strongpoint and disadvantage and improvement method. Moreover, the paper discusses the feasibility to supply heat and economize energy measure for automobile air-condition in winter.
