Ventilation for the hangar

A hangar is a quickly assembled room. The hangar is used for storage and office premises, factories, warehouses, car services and parking lots.

Ventilation in the hangar provides conditions that meet sanitary and technological norms of humidity, temperature and air exchange.

Types of hangar ventilation

The hangar’s natural ventilation system provides ventilation and air exchange due to the pressure difference between internal and external air flows. No additional equipment is required for natural ventilation of the hangar. But the disadvantage is that it depends on the wind speed and air temperature. Therefore, it is impossible to control air exchange and humidity in the hangar with natural ventilation.

The forced ventilation system of the hangar is implemented in accordance with the purpose of the building:

• supply-exhaust mechanical ventilation with cleaning filters;
• supply-exhaust mechanical ventilation with automated control of such parameters as humidity and air temperature;
• Exhaust ventilation;
• Climate control system.

Electricity is used to ensure forced ventilation of the hangar. Thanks to the operation of the equipment, proper ventilation is carried out in the hangar regardless of the season and weather, but there are constant costs for electricity.

Ventilation standards in the hangar

Proper ventilation in the hangar is regulated by the sanitary rules of SNiP 2.04.05-91*U:

• for the ventilation of the premises, systems are provided that prevent the emergence of unpleasant odors and the accumulation of harmful production emissions;
• the concentration of harmful substances in the incoming air should not be higher than 30% of the maximum permissible concentration;
• in the areas near the gates and doors of production buildings, air-heat curtains should be provided, the air temperature in the room should not drop below 12°C when the doors are opened.
