太阳能喷射制冷系统微小型喷射器试验研究

蒸汽喷射式制冷系统可以采用太阳能、地热、废热等为驱动热源,以水等低沸点的环境友好工质为介质,不仅可节约大量的电能,而且还保护了环境。针对太阳能喷射式制冷系统中微小型喷射器的设计和运行问题,本文试验研究了微小型喷射器的运行参数和结构参数对喷射性能的影响,为微小型喷射器设计和运行提供了指导。

Experimental Studying of Performance Characteristics of Small-scale Steam-ejector Applied in Solar Jet Refrigeration

Steam-jet refrigeration system not only save much energy,can be operated using energy sources such as solar energy,geothermal energy and waste heat,but also friendly to environment,can be used such as water designed for low pressure refrigerants.Because of the designing and running problems of small scale ejector applied in solar ejector refrigeration system,this paper experimentally investigates the controlling parameters of a steam ejector,including operating conditions and structure parameters,and the conclusions useful for the practical system.
