地下车库通风与防排烟系统设计的探讨

Design of Ventilation and Smoke Control in Underground Garage

对比GB50016-2006《建筑设计防火规范》、GB 50045-95《高层民用建筑设计防火规范》、《全国民用建筑工程设计技术措施-暖通空调.动力》(2009版)和《汽车库、修车库、停车场设计防火规范》中关于地下车库的通风排烟系统设计方面的内容,探讨了车库的送风量、平时排风量与消防排烟量计算方法和排烟排风合用的设计要点,阐述了地下汽车库的排烟系统与通风系统兼用的实用性[1-4]。

the content of the ventilation and smoke exhaust for underground garage in Code of Design on Building Fire Protection and Prevention（GB50016-2006）, Code for Fire Protection Design of Tall Buildings（GB 50045-95）, National Technical Measures for Design of Civil Construction（Heating, Ventilation and Air Conditioning）, and Code for Fire Protection Design of Garage, Motor Repair Shop and Parking Area（GB50067-97） are compared, discussing about the design points of combination of smoke and exhaust system and calculation method of air output, exhaust air and exhaust smoke volume of exhaust systems and ventilation systems in underground garage. It is possible and economic to use one system only instead of two different systems.
