摘　　要：对 3种复合喷射 (压缩—喷射 ,吸收—喷射和吸附—喷射 )制冷循环进行了理论分析 ,认为单一循环制冷系统加喷射器 (泵 )后的复合循环系统的COP值有所提高 ;探讨了提高复合制冷循环系统COP的几个关键问题 ,包括喷射器的设计、工作温度、冷凝温度、蒸发温度等 ,并对复合制冷循环系统的发展作了展望。Theoretically analyses three complex ejecting refrigeration cycles, namely compression-ejection, absorption-ejection and adsorption-ejection. Considers that COP value of the complex cycle system, i.e.single refrigeration cycle plus jet pumps, can be increased. Discusses several key issues to raise COP value of complex ejecting refrigeration cycle, including design of ejector, working temperature, condensation temperature, evaporation temperature etc. Prospects its development.
