摘要
介绍沸腾换热理论及制冷空调系统用微通道换热器的研究现状,对CO2应用于微通道换热器的发展进行分析,通过与其他制冷剂的热物理性质相比,分析CO2在微通道换热器内的沸腾换热特性,为今后的研究方向提供参考。
The boiling heat transfer theory and research status of microchannel heat exchang- er for refrigeration and air-conditioning system are introduced. The development of CO2 used in microchannel exchanger is analyzed. Through comparing with other refrigerant＇s thermophysieal properties, the boiling heat transfer characteristics of CO2 in microchannel heat exchanger is ana- lyzed, which provides the references for the future research direction.
