摘要
以R600 a/R23两级自动复叠制冷系统为例,研究了不同配比条件下,制冷系统中的特征点温度在降温过程中变化特性。试验表明混合制冷剂的配比是自动复叠制冷系统关键问题,通过控制关键点的温度可以判断混合制冷剂的最佳配比。
Two - stage auto - cascade refrigeration system is developed with R600a/R23, the characteristics of temperature change in the course of temperature decreasing process have been analyzed in different proportion of refrigerant mixture. Test shows that the proportion of refrigerant mixture is the key , and optimization can be judged in control of key temperature.
