适用全气候的高效CO_2跨临界商业冷冻解决方案

High efficiency CO_2 transcritical commercial refrigeration solution for all climates

提出一种适用于全气候的高效CO_2跨临界系统,并通过在寒冷、温和、温暖3种气候条件下模拟带喷射器的CO_2跨临界系统能耗,对比系统在不同条件下的节能效果。结果表明,与典型CO_2跨临界系统相比,带喷射器的CO_2跨临界系统在3种气候条件下均有节能效果,且在温暖气候条件下节能效果最好。

A kind of high efficiency CO_2 transcritical system which is applicable for all climates is proposed. The energy consumption of CO_2 transcritical system with vapor ejector is simulated in cold,mild and warm climate,and the energy-saving effects of system under different conditions are compared. The results show that compared with the typical CO_2 transcritical system,the one with vapor ejector has energy-saving effect under three different climatic conditions,and the energy-saving effect is the best in warm climate.
