摘　　要：R404A制冷剂是由R125、R143a和R134a组成的近共沸制冷剂,它主要应用在温度为-20^-50℃的商用制冷设备中,是替代R502的首选制冷剂。但目前它在商用制冷中还没有得到广泛应用。本文首先简要介绍了R404A制冷剂的组成及其性质,然后分析了它在当前市场中的应用情况,结合R404A发展的驱动力分析,指出了R404A在未来有着广阔的市场前景。R404A is a near - azeotropie refrigerant that is made up of R125, R143a and R134a . h is mainly used in the equipments that the temperature varies from - 20℃ to - 50℃, and it is the first choice to substitute R502.At preseent, however, it has not been widely used in commercial refrigeration equipments. The component and its characteristics of R404A are introduced in this paper, then its application in the market is given, at last, a wide market foreground for R404A is advanced combined with the development drive of R404A.
