【摘要】 对非共沸混合制冷剂R290/R600替代R404A用作冷柜制冷剂进行了全面的分析。文章比较了R290/R600与R404A、R134a以及R600a的基础热物理性质,并对它们的冷柜标准工况和变工况循环性能进行了详细的理论计算和分析。R290/R600的综合性能要优于R404A,而且更加适合环境保护的要求,可以作为新一代的冷柜制冷剂。更多还原

【Abstract】 Azeotropic Hydrocarbon Mixtures-R290/R600 used as a refrigerant for freezer is analyzed in detail.The thermophysical properties of the new refrigerant and the normal refrigerant R134a,R404A,R600a and R290 are compared,besides the performances of the freezer refrigeration cycle of standard operating condition and that of variable operating condition are calculated and analyzed theoretically.The result indicated that the combination property of R290/R600 is better than R404A and R290/R600 is more helpful to the environmental protection.So it can be used as the freezers’ alternative refrigerant.更多还原
