摘　　要：当前应用的基于PHOENICS软件的通风窗热损失分析方法忽略了对通风数理模型的构建,无法分析自然通风的类型和特点,导致通风窗热损失的模拟出现较大偏差。为此提出新的居民建筑室内热环境通风窗热损失模拟方法。构建通风数理模型,分析热压作用、风压作用和两者共同作用下的自然通风,根据分析结果计算居民建筑室内热环境通风窗的热损失,利用AIRPAK3.1软件模拟通风窗在热环境下的热损失。仿真结果表明,所提方法可有效获取不同高度下平面温度随时间的变化情况,精准完成通风窗热损失的计算和模拟。Currently,the method based on PHOENICS software ignores the construction of ventilation mathematical model and is unable to analyze the types and characteristics of natural ventilation,resulting in a large deviation in the simulation of heat loss of ventilation window.Therefore,a method of simulating the heat loss of ventilation Windows in an indoor thermal environment of residential buildings was proposed.Firstly,the ventilation mathematical model was built to analyze the natural ventilation under the thermal pressure,wind pressure and both of them.According to the analysis results,the heat loss of ventilation windows in an indoor thermal environment of residential buildings was calculated.Finally,AIRPAK3.1 software was used to simulate the heat loss of the ventilation windows in a thermal environment.Simulation results show that the proposed method can effectively obtain the variation of plane temperature with time at different heights,and accurately calculate and simulate the heat loss of the ventilation window.
