| 摘 要： | 应用P-R方程编制了容积绝热指数与温度绝热指数的计算程序,利用该程序计算了HFC-161,HC-290,HC-600a的绝热指数,绘出了三种制冷剂的容积绝热指数与温度绝热指数随对比压力与对比温度变化的图线,并加以对比与分析。结果表明,HC-600a的两种绝热指数值都较小,在压缩机进出口条件一致的状况下,较适于作为替代制冷剂。

| Abstract: | A program was developed to calculate volumetric adiabatic exponent and temperature adiabatic exponent based on P-R equation.This program was used to calculate adiabatic exponent of HFC-161、HC-290 and HC-600a,graph lines which describe the relationships between volumetric adiabatic exponent,temperature adiabatic exponent and reduced pressure,reduced temperature were drawn.After comparison and analysis,both adiabatic exponents of HC-600a were smaller,thus it is more suitable for alternative refrigerant under the same import and export condition of compressor. |
