摘要
在汽车空调中,具有对环境友好性和优良的热物理特性的天然工质CO2与其他制冷剂相比有独特优势。近年来,美国、欧洲和日本等发达国家和地区的研究者们不断尝试将CO2应用于各种可能的制冷、空调和热泵系统。本文从制冷剂的替代、跨临界循环以及汽车空调特点上阐明无毒、不可燃的二氧化碳制冷剂将是下一代汽车空调的首选。
Through comparing CO2 with other refrigerants, the advantages of CO2 as a natural refrigerant are due to its environmental benign and good thermal properties in the automobile air-condition system. Recently the extensive research and development work on refrigeratory air-condition and heat pump technology are used in some developed countries.In the paper, according to the replacement of refrigerants, transcritical cycle and characteristics of automobile air-conditioning,natural Refrigerant C02 with non-flammable and non-toxic advantages is a primary candidate for next-generation automobile air-conditioning.
