Fitness single block of channels: the ventilation exhaust duct and chimney, with the division of the entire height of tight bulkheads. Based on practice, with a vent pipe is better positioned a few meters away from the chimney. Hard no requirements, and the views as much as stove-makers and kaminschikov. Chimney height of 5 meters provides good traction. The chimney should rise above the surrounding buildings and trees, is insulated to maintain high temperature in the tube, to ensure removal of combustion products in all weather conditions. The level of headroom chimney fire should be carried out above the pipe ducts.
Number of exhaust air limited bandwidth (the pipe section and the velocity of the flow). Narrowed section of the channel, littering, irregularities inside the pipe and complex form of the channels can be factors that impair the original draft. The flow of air passing through the channel causes noise. With a strong draft in the chimney fire can hear the sound – 'a buzz in the chimney. " Optimal cross-section of the channel and maintaining a low air flow rate, we achieve the lowest sound performance. Smoke and air ducts should be according to established standards and common sense, at regular intervals to examine and clean: chimneys before heating season and check again in quarter vents – once a year. Better twice a year to invite a chimney sweep than once – the fire department.
Thrust and efficiency of the ventilation system ventilation system with a natural impulse depends on the variables factors – pressure, air temperature, wind speed and direction. In winter even have to cover the louvers (to reduce the hood), due to unavoidable heat losses. In summer natural ventilation does not work practically. Enlarge traction, creating a vacuum in the vent risers, you can install on the top of the device ventkanalov – deflector or spherical rotary turbines.
