Determination of number and location of supply and exhaust ventilation units

All rooms of the building are provided with a single plenum ventilation system. Since the club building does not have a basement, the plenum chamber is located on the first floor of the building. Air is supplied to the rooms using horizontal ducts. Rooms for accommodation of ventilation equipment are not recommended to be located directly behind the enclosing structures of the auditorium.

In the auditorium we design separate mechanical exhaust ventilation using a roof fan (B4). A separate mechanical exhaust ventilation system is provided from bathrooms, film projection, rewinding and radio unit (B2), while radial fans installed outside the building are used. Only channels from related rooms can be combined into one exhaust plant. Air from such rooms as storerooms, artistic, box office is removed by one exhaust ventilation system with a natural impulse (VE). When combining channels into exhaust plants, it should be taken into account that the range of the plant with natural traction is not more than 10 m, and with mechanical - not more than 30 m.

Selection of basic solutions for supply and removal of ventilation air for building premises. resolving the issue of duct material and placing the latter in the building

The layout of the network of air ducts is carried out using air ducts and shaped parts produced by LLC NIC "Master" in Minsk.

Air ducts of round section are placed along corridors (rooms No. 14, No. 10). They are in the set ceiling design.

Air is released through the shafts. The outer walls of the exhaust shafts are insulated to avoid condensation of water vapors from the removed air. Ducts are also insulated during external gasket. To protect against rain, snow, debris, an umbrella is installed above the mechanical exhaust ventilation shaft. Exhaust shafts are withdrawn 0.5 m above the flat roof.
