【摘要】 提出新型冰箱混合制冷剂HFC 152a/HFC 125(质量比:85/15)。基于制冷剂物性计算软件REFPROP7.0,开发了制冷剂热物性计算程序,对此新型冰箱混合制冷剂的热力学性质进行了计算,并由此制作了其压焓图及饱和性质表,同时给出了制作图表过程中制冷剂物性计算选用的状态方程和实际气体热力学计算公式。为混合工质HFC 152a/HFC 125进一步科学研究和工业应用提供了基础数据。更多还原

【Abstract】 A new refrigerant mixture HFC152a/HFC125 (mass: 85/15) was proposed to replace the refrigerant CFC12. On basis of the software REFPROP 7.0, a computer program calculating thermodynamic properties of refrigerants was developed and the thermodynamic properties of the new refrigerant mixture were calculated. The pressure-enthalpy diagram and the saturated properties of this new refrigerant mixture were presented.更多还原
