摘要(Abstract):

运用绝热毛细管的均相流模型 ,数值模拟了毛细管内制冷剂的质量流量 ,并进行了实验验证 ;分析了R12、R13 4a两种制冷剂在毛细管内的流动特性 ,讨论了过冷度、毛细管长度、入口压力、出口压力等参数对制冷剂质量流量的影响
Based on the Homogeneous Flow Model of adiabatic capillary tubes, a counting program for numerical simulation of the mass flow rate of refrigerant in capillary tubes is developed. The results obtained are compared with the measured data and then analyzed. The investigations include the effects of refrigerant subcooling, capillary length, condensing pressure, evaporating pressure with refrigerants of R12 and R134a respectively on the mass flow rate of refrigerant.
