摘要(Abstract):
随着全球环境问题日益加剧,制冷空调行业氟利昂类制冷工质的替代受到普遍关注,绿色环保制冷剂R744因此得到重新启用。单一工质R744热泵系统存在放热侧压力高、系统效率低的缺点,在R744中混入合适的第二组分工质可以有效降低压力或同时改善其效率。本文主要从R744混合工质的热物性、流动传热特性、应用于热泵空调系统、应用于复叠式制冷系统等方面进行综述,并针对研究现状,分析了目前R744混合工质研究存在的主要问题,指出了未来的研究和发展方向。
With the gradually-serious environmental problems in the world,it has received extensive attention that the Freons used in refrigeration and air conditioning system will be phased out. And then the eco-friendly working fluid R744 regained its new life. However,the heat rejection system is high and the system efficiency is relatively low for pure R744 heat pump system,which can be solved on mixing R744 with suitable second component. In this research,it is prezented from R744-based mixture thermophysical properties,flow and heat transfer characteristics,system performance when used in heat pump and air conditioning system,and casade refrigeration system. The main problems in the current researches are proposed,and the research and development in the future are given.
