【摘要】 文中提出了一种五级自动复叠制冷循环,根据不同的系统采用不同的制冷工质和不同的混合配比,可以获得不同的蒸发温度,作者分析了非共沸混合工质的组分选取原则并选取了组分,探讨了适用于自动复叠制冷系统混合工质计算的方法,根据要求选择了R22、R23、R14、R740和R728五种制冷工质作为系统循环工质,并对混合工质的配比进行了模拟计算,得出了模拟最优配比。更多还原

【Abstract】 In this paper, a five-stage Auto-cascade refrigeration cycle brought forward.According to the experiences that different systems with different components and proportion of mixed refrigerants can result in different evaporating temperature,the author analyzed the components selecting principle of no-nazeotropic Mixed-refrigerants and selected the components,discussed the calculated methods of mixture-s in ARC system.R22、R23、R14、R740 and R728 are selected for this system based on the request-ed conditions,at the same time a process of analog calculation was done to get a optimization ratio of mixture.更多还原
