为研究通风对室内温湿度分布和壁面结露的影响，提出了一种三维非稳态数学模型。在含有湿热源的环境中，利用Fluent软件对该模型进行数值计算，分析了通风强度对空间和墙体壁面温湿度分布的影响，并模拟不同通风强度下，壁面结露面积的动态发展过程。模拟结果表明：通风强度对室内空间及壁面温湿度分布和结露形成均有显著影响。因此，对于湿气较重的场所，合理改变通风强度可有效改善室内热湿环境和壁面结露等问题。

In order to study the effects of ventilation on distribution of indoor temperature, humidity and surface condensation on walls, a three?dimensional unsteady mathematical model is presented. Under the conditions of damp and hot sources, the Fluent software is applied to numerical calculation in this paper, effects of the intensity of ventilation on distribution of temperature and hu?midity in space and on the surface of walls were explored and the dynamic development process of condensation area of surface on walls are simulated under different intensity of ventilation. The simulation results show that the intensity of ventilation has a big in?fluence on distribution of temperature and humidity in space and on walls surface, as well as the development process of condensa?tion. In the places of higher moisture, changing the intensity of ventilation reasonably can effectively improve the problems of hot hu?mid environment and surface condensation on walls.
