Mechanical Ventilation

Natural ventilation is a ventilation system, which does not contain any items of electrical equipment. The air moves in natural ventilation due to temperature difference, pressure difference air outside the room and the air inside it. All high-rise buildings ventilated by natural ventilation, which acts in them with the systems of vertical channels (or ducts) with bars in bathrooms and kitchens. All air ducts have access to the roof of the house, where they established a special attachment, called deflectors, whose task is to strengthen, due to wind, sucking air masses. Of fresh air through a slit located in the openings of windows, doors, or else through open vents. The work of natural ventilation depends on uncontrollable factors, man: t air, the direction and strength wind.

Aside from these factors are often clogged ducts mud, debris, dust, and fresh air is greatly reduced when the flat plastic box set. Mechanical ventilation system used appliances and special equipment that allows you to move the air flows over long distances, if necessary, cleaning and fueling it. Such systems provide the required level of air and do not depend on external factors. However, their value is high enough, and maintenance costs translate into "tidy" sum. Quite often the use of so-called mixed (or combined), ventilation, when simultaneously using mechanical and natural.

For example, in air ducts installed kitchens and bathrooms are small fans. Just apply "smart" fans, where is the place automation. Such fans are included in the job when the limit is increased humidity, the lights, etc. Forced ventilation in mixed schemes, improved by supply air valves that are installed in the glass, through which the Air enters from the street. They can contain sewage filter, to reduce noise levels and can regulate the amount of intake air into the room. Whatever it was, only an expert can detect more economical and efficient type of ventilation in each case. Forced ventilation systems ventilation, organize supply to the premises cleaned, fresh air, instead of being removed from them. Often, the supply air is subject to additional processing: cleaning, humidification, heating, etc. This processing is performed by special climatic equipment. Exhaust ventilation system ventilation intended for cleaning of contaminated waste or air flow from the premises. In general, the premises shall be established and inlet and exhaust ventilation system. Their work provides a well-coordinated balanced efficient performance of ventilation systems. And the exhaust and forced ventilation can be installed directly in the workplace (a local ventilation) or fully for the required premises (general exchange). Local ventilation is a matter of fact, local ventilation is called, which provides delivery (local exhaust) of air at a certain place, or it removes the (local exhaust) air pollution from it. The purpose of general ventilation general dilution ventilation, as air supply and exhaust – an organization of ventilation in general, or is it mostly. Such exhaust ventilation systems contribute to the uniform removal of air masses from the premises served, and air supply is fed evenly distribute the air and the volume of the room.
