环境友好型跨临界CO_2制冷工质的应用与研究进展

Progress of research and applications of the environmental friendly transcritical CO2 refrigerator

通过回顾CO2制冷工质的开发和应用历史,分析了这一环境友好型材料在替代CFC方面发展迟缓的原因,综述了采用跨临界循环系统的研究进展.对采用CO2为工质的汽车空调、制冷、热泵系统的应用情况进行了总结和评价,指出了目前研究的不足和今后的发展前景.

Through looking back the development and application history of CO2 used as refrigerator, the reason of a tardness in the CFC replacement of this environmental friendly material was analysed and the research progress of the transcritical cycle of CO2 was reviewed in the present paper. Meanwile, the application of CO2 used in the areas of the automotive air-condition,refrigeration,heat pump systems was summarized and evaluated, the inadequacy of the current research and the prospect was pointed out as well.
