摘 要:基于两相区流型及换热规律变化,采用分相模型建立了空调器冷凝器的稳态分布参数模型。在空调工况下进行理论计算,得到制冷剂压力、空泡率、温度、干度等沿管长方向的变化规律,并将结果与均相流模型进行比较,精度有所提高。A steady simulating model of distribution parameters was proposed for room air conditioner considering not only the characteristics and distribution of the two phase flow pattern,but also the change of heat transfer correlation in each flow type.Through the simulating computation for the steady operation of the system in the air conditioning state,the pressure,void fraction,temperature,the quality of refrigerant and so on vary with the length of the tube.The results of computation well agree with these of experiment,compared with the average phase flow model,the accuracy of the simulating model is improved.The study will provide theory basement for the analysis of the performance of the condenser.
