Parking Garage Ventilation Systems

Exhaust and supply fans are used in conjunction with ductwork to distribute air throughout the parking garage providing a common system for both pollution and smoke control.

Parking garage ventilation systems.

Systems if permitted by local codes. Design and implement the system. When the property was constructed in 2002 building designers did not incorporate a co sensor system in the garage ventilation strategy so applicable code required the garage ventilation system to operate at its maximum design ventilation rate during building occupied hours. Fitting ductwork to match the location of existing exhaust grilles or louvers is difficult and creates system inefficiencies and cost increases.

The system is shall be arranged to operate automatically upon detection of vehicle operation or the. Taminated air and fumes from parking garages exhaust systems utilizing multiple exhaust inlets shall be designed so that exhaust inlets are distributed in such a manner that no portion of the park ing garage is more than 50 ft 15 240 mm from an exhaust inlet. Ventilation is also a requirement in the event of a fire to remove smoke and to provide a clear access for firefighters. Designing a parking garage ventilation system.

In multi level parking garages or single level structures of extensive area independent fan systems each under individual control are recommended the ventilation system in parking garages in general moves large quantities of air through large openings without extensive ductwork. The following steps are sufficient to create an initial induction ventilation system design. A typical ventilation system for a smaller garage. Our knowledge and experience with ventilation systems is now being used to produce an innovative solution for enclosed parking facilities.

Enclosed or underground parking garages are ventilated. Polluted air is evacuated through openings close to the floor and the roof. 404 1 enclosed parking garages. The fresh air is supplied through openings in the outside wall.

A computational fluid dynamics cfd analysis is often required to prove and further refine the design. Ventilation of parking garages using jetfan systems howden is a world leader in the technology of air movement. Fans may need to be reoriented added or removed. Such exhaust inlets shall be installed so that the highest elevation.

For larger buildings and garages it is common to use outlet air from the ventilation systems in the surrounding buildings as fresh make up air to the garages. Traditional parking garage ventilation systems combine supply and exhaust fans with ductwork to move fresh air in and pollutants smoke and harmful emissions out. Although natural ventilation may be sufficient for open and semi open parking lots channeled mechanical or jet fan ventilation systems should be used in underground and closed parking garages in order to prevent excessive co concentration levels the jet fan ventilation system is one of the most widely used. Mechanical ventilation systems for enclosed parking garages shall be permitted to operate intermittently in accordance with item 1 item 2 or both where 1.
