【摘要】 复叠循环是常用的获得低温的方法。采用环保制冷剂R23和R134a复叠制冷循环是低温箱发展趋势之一。本文根据相关程序,计算了不同条件下R23/R134a经典复叠循环和自然复叠循环的运行参数,分析比较这两个循环的运行特性,以期对于深入研究自然复叠有所裨益。更多还原

【Abstract】 Cascade cycle is the usual refrigeration cycle of obtaining Low tenmperature. Using the cascade refrigeration cycle of R22 and R134a is the developing trend of the low temperature refrigerator. Based on related program, the tunning parameters of classical cascade cycle and that of autocascade cycle on different conditions ate calculated,and then the running characteristics of the two cycles are compared,which may help the further research on autocascade cycle.更多还原
