58 K),the binary mixtures of R744 and nature working fluid(such as R170 and R1150) were introduced to reduce R744 triple point temperature and substitute for R13.
为了使R744在复叠式制冷系统中运行的最低温度突破三相点的限制,用R744与自然工质(如R170或R1150)混合组成二元混合物,使其突破R744的三相点温度,完全使用自然工质混合物替代R13,在复叠式制冷系统的低温环路中运行。

The result that the COP of R290/CO_2 is lower than that of R22/R13 is found, by thermodynamic analyzing of natural refrigerants R290/CO_2,NH_3/CO_2 and conventional refrigerants R22/R13 cascaded refrigeration cycle.
通过对自然工质R290/CO2和NH3/CO2与常规工质R22/R13的复叠式制冷循环的热力学分析,得出R290/CO2复叠式制冷循环的COP比常规工质R22/R13的低,提出CO2低温循环采用膨胀机代替热力膨胀阀,从而提高了COP。
