摘　　要：从制冷系统热动力学观点出发，在分布参数的基础上建立了一个房间空调器的稳态模拟模型；分析了换热器的两相流特性及分布，并且针对每一种流态提出相应的热交换关系式。换热器模型基于两相流分析，在动量、能量、质量三大守恒方程基础上引入一个反映两相之间相互关系的关系式以使方程可解。实验表明，与计算机模拟结果吻合较好，与均相流模型相比。From the view of thermodynamics of refrigeration system,a steady simulationg model based on distribution parameters is proposed for room air conditioner.In this paper the characteristics and distribution of the two phase flow pattern in the heat exchangers are analyzed and the heat transfer correlation is recommended for each flow type.The model of heat exchangers for room air conditioner are based on two phase flow analysis and an equation which reasonably reflects the interphase relation is introduced so as to make the model equations solvable.With the equations of energy,momentum and quality,a solving system model is formed.then,the simulating computation is conducted for the steady operation of the system in the air conditioning state.the results of the computation well agrees with the experiments.Compared with the average phase flow model,it is indicated that the accuacy of the simulating model is improved.
