商业建筑地下停车场通风问题的剖析

Analysis on Ventilation of an Underground Parking-area of Commercial Building

参照《室内空气质量标准》、《建筑设计防火规范》、《汽车库、修车库、停车场设计防火规范》、《高层民用建筑设计防火规范》、《轻型汽车污染物排放限值及测量方法(中国Ⅲ、Ⅳ阶段)》,对影响地下停车场通风的相关参数进行计算对比,计算结果满足室内污染物允许标准通风量、平时通风量、消防排烟量,为地下室车库通风设计提供依据。

Referring to indoor air quality standards, code of design on building fire protection and prevention, code for fire protection design of garage, motor-repair-shop and parking-area, code for fire protection design of tall buildings, limits and measurement methods for emissions from light-duty vehicles （Ⅲ, Ⅳ ） the relevant parameters to impact ventilation of underground parking-area were calculated and compared. The results meet the volume of ventilation by the standards of indoor air poUutants to allow, the volume of normal ventilation and fire smoke ventilation for the underground parking-area design, and provide basis for ventilation design of underground parking-area.
