One of the major causes of air pollution in underground parking lots is the exhaust gas emitted from cars. There are a lot of harmful chemical substances in exhaust gas. One of them is CO gas whose concentration needs to be kept under the limit by using ventilation facilities. An economic ventilation system is commonly used in underground parking lots to keep polluted zones to a minimum. This helps maintain good indoor air quality and prevents condensation during summer. It sprays car exhaust gas in underground parking lots in high speed and swiftly induces gas to the exhaust pipe.
The single fan system is specially designed and manufactured with a low-noise fan, a simple structure and a precise specification to support ventilation facilities in large spaces and underground parking lots.
Shortens floor height as it requires no ductwork
Supports high-efficiency ventilation by mixing airflow

PROBLEMS OF AIR STRATIFICATION In HVAC Air Handling system, air stratification resulted from the improper design inherent in moving air streams by keeping air streams of different air temperatures from mixing effectively for a long distance. A [...]
These are series of damper assigned in a bank arrangement both horizontally/vertically to cover a required opening area. The main advantage of damper bank is control as well shut off flow of a larger area. Damper bank can also be synchronized to modulate flow [...]
