摘要
随着我国对环境保护的重视,采用常规制冷剂的热泵机组面临着淘汰和替换。采用自然工质CO_2作为制冷剂的跨临界CO_2热泵机组,因其具有高效、节能、环保等特点被广泛的应用和推广。阐述了跨临界CO_2热泵技术国内外研究现状及工作原理,并介绍了跨临界CO_2热泵技术的应用情况。
Along with the advocating for environmental protection in China, heat pump sets adopting conventional cooling agents are becoming obsolete and will be replaced in the future. A transcritical heat pump set which adopts CO2, a natural working medium, as the cooling agent was described in this paper. This machine set has been widely adopted as it has the advantages of high efficiency, energy saving and environmental protection. In the paper, research status of the transcritical CO2 heat pump technology both at home and abroad was discussed, its working principle was introduced and its applications were presented.
