地下车库自然通风数值模拟分析研究——以四川阆中某车库工程为例

Research on Numerical Simulation of Natural Ventilation for Underground Parking Garage

该文以四川阆中某车库工程为对象,通过在车库顶部设置自然通风口的方式解决车库自然通风和采光问题,借助Airpak数值模拟技术对比分析设置机械通风系统和自然通风口两种工况下过渡季节车库的气流分布、温度分布和CO浓度场,说明车库采用自然通风口解决车库通风问题在实际工程中的可行性。

The underground garage of Redbud City project in Sichuan was selected as the study object. By setting natural vents on top of the garage, the issue of natural ventilation is solved. Airpak numerical-simulation technique has been used to analyze air distribution,temperature distribution and CO concentration distributionof the garage under the condition of mechanical ventilation system and natural vents system in transient season. This study shows that it＇s feasible to solve the problem of ventilation in practical engineering through natural ventilation vents.
