Fundamental design solutions

SUPPLY AND EXHAUST VENTILATION SYSTEMS.

The structural solution of the scheme of organization of air exchange in the auditoriums should be organically connected with the volume and layout solutions of the hall. In addition, the air exchange organization scheme should be adopted taking into account the working temperature difference between the supplied supply air and air in the area of ​ ​ spectators (working zone) in the cold period of the year and taking into account the design features of the auditorium.

For auditoriums, clubs and cinemas with 150600 seats, plenum ventilation systems with a mechanical impulse of air movement are designed, operating in the warm period of the year in the outside air, and in the cold period with partial recirculation. Exhaust ventilation systems may be naturally or mechanically induced. The clubs design a common plenum system of the auditorium and scenes, separate exhaust systems. Supply air is supplied to the stage due to overpressure in the hall created by the supply system. Through the stage, 17% should be removed, and through the auditorium 83% of the total volume of air removed from the hall. The rest of the air shall be removed through recirculation and exhaust devices of the auditorium.

Mechanical exhaust from the block of film projection and other technical rooms is designed in the building.

Natural exhaust ventilation is provided from the auditorium, stage premises, as well as from separate or separate administrative and economic premises.
