摘　　要：为了提高制冷效率,降低换热器的热负荷,减少热能对制冷系统的注入,采用减压发生和液体喷射泵来推动制冷剂的循环,从而使整个制冷流程处在较低焓值下循环。无须给系统注入温度较高的热能,而只是利用吸收循环热,在降压条件下进行发生,大大降低了单位制冷量的能耗量,这优越于当前各类气体喷射吸收复合式制冷技术和其他各类制冷技术,其经济性是显而易见的,流程是简便易行的。To improve refrigeration efficiency,drop heat load of heat exchanger,and reduce quantity of heat,we can reduce the evaporation pressure and use Liquor ejector on refrigerant cycle to improve the refrigeration medium cycle.So the whole refrigeration technological process will be in lower enthalpy cycle.This new technology is no need for higher temperature heat energy in the refrigeration system,only make use of absorption heat cycle.The evaporation progress can be taken by dropping pressure,reducing energy by a big margin per unit refrigeration.This new technology has its advantages over other complex gas ejecting absorption refrigeration cycle related technology and else refrigeration technology.Its economic advantages is obvious,and its technological process is simple and easy to learn.
