地下车库自然通风的设计

Design of natural ventilation in underground garage

针对地下车库机械排风系统在管理、运行方面存在的不足,提出一种以自然通风为主,机械排风为辅的地下车库通风系统;探讨了该通风系统的设计原理;结合实例工程,在设计中应用数值模拟方法和能耗分析软件DeST进行分析;该通风系统在保证地下车库内空气品质良好的同时,节省运行费用,具有节能意义.

For the shortcomings of the management and operation in mechanical ventilation system for underground garage,this paper presents a ventilation system that comprises a natural ventilation as a chief and a mechanical ventilation as an assistant.Introduces the design principle of the ventilation system,as well as numerical simulation methods and energy consumption analysis software DeST in the design of the application.The ventilation system in underground garage is ensuring good air quality and saving operating costs with energy efficiency significance.
