 The following information for reference only and has nothing to do with our services: 

 Provisions of the ventilation system design, but the actual project is complex and diversified, and the design caused by the different understanding of the specification provisions basement ventilation design process to produce something different 

 Of view. The architectural design of this article by summing up the hope to increase consensus, reduce differences, so that the ventilation system in the practical engineering design more reasonable. Underground garage usually ventilation and smoke extraction system 

 Selection of underground construction of the valve compared to building on the ground, closed a high degree of pollutant easy to spread, underground garage, car exhaust emissions in the course of the campaign contains a lot of harmful gases. 

 Sulphides of lead, such as nitrogen oxides and particles, in particular, to the effect on people, so designers often use mechanical ventilation to the underground garage. Provisions in the heating, ventilation and air conditioning design specifications, 

 When the density of the diffuse gas is heavier than air should be discharged from the lower area two-thirds of the total exhaust volume, the upper discharge-third of the total air volume. Vehicle fleet exhaust, in terms of density greater than air density 

 In the exhaust system using this method to exclude gas. Order to facilitate the regulation and control of the ventilation system, additional ventilation manifold on the next row of gas control valve, in practical engineering design 

 Common outside the multi-leaf regulating valve and ℃ smoke fire dampers two valve. I do a simple analysis in recent years, the actual engineering design for reference. Usually to get off the construction area of ??more than
