Fresh and clean indoor air is of particular importance for health, it affects a person's mood, vigor and sleep.
The ventilation system is present in any residentialand warehouse buildings. In apartments, as a rule, ventilation in the kitchen, based on natural air circulation and carried out with a single exhaust duct, is equipped. Oxygen enters the room through the door and window slots, and is removed through the channel due to temperature difference. The space of the ventilation ducts should never be disrupted during the repair process, because of this, tenants on the ground floors may remain without ventilation.
Ventilation shafts are not without flaws.The functioning of such a system is influenced by atmospheric conditions - wind speed and air temperature. In the cold season, the circulation is ensured by a noticeable temperature difference, for the same reason in the summer it is minimized.
Most homes and apartments today are installedplastic window systems, characterized by high tightness. Despite their convenience and the preservation of heat in the winter, they practically do not let the air through, which reduces the quality of the ventilation system. As it is irrational to refuse them, artificial ventilation, for example, the Alpine window leaf, is the way out. Reviews of this device, as a rule, are positive, many people note the supply of a sufficient amount of air purified from exhaust gases and dust, as well as an improvement in the microclimate in the apartment. The Alpine vent is a comprehensive system that does not require drafts and is designed for office and residential premises.
High-quality air exchange affects not only the performance, but also on human health. For its formation requires compliance with several conditions:
Alpine window, the price of which is inwithin 3,000 rubles, is able to ensure compliance with all these conditions. It is best suited for rooms with insufficient air exchange. Its use is especially justified in apartment buildings of the old stock, in which ventilation is not fully functional, or does not function at all. The need for it increases when replacing wooden windows with modern plastic.
The manufacture of this device is engaged inseveral domestic firms. For its installation requires the creation of a hole in the outer wall using diamond drilling, its diameter should be about 14 cm. A blower is placed in the hole, complemented by sound and heat insulation materials. From the street, a fine grid or grid is fixed, which prevents the penetration of precipitation, debris and insects. The blower is closed from the inside with a special box, which has a damper regulator and a high-quality synthetic filter. The volume of incoming air is regulated by the damper. To change its position, use a pen or a special cord.
Alpine vent provides intakethe necessary volume of already purified air, while standard ventilation removes used. If the natural system is insufficient, a forced additional system is mounted in the duct.
Оптимальным вариантом для монтажа становится space above the window. This device is indispensable in apartments located on the ground floors with windows overlooking busy roads, in crowded rooms and in rooms with no windows. Alpine vent is not suitable for installation in the bathroom and in the kitchen, as it does not replace exhaust ventilation.
Regardless of the type of hood availableto ensure continuous air flow to the exhaust devices during the entire path of its movement must be installed overflow grilles. For the proper organization of the flow, it is important that the most polluted zone is the last in the general chain. That is why ventilation in the kitchen and in the bathroom is of particular importance. In the absence of gratings, there should be free space between the floor surface and the door, its width should be at least 2 cm. Only in this case the functioning of the system will be sufficient.
As noted earlier, the flow isfresh air in two ways - forced and natural. Infiltration is the supply of oxygen through gaps and openings in wall structures, doors, and windows.
Wooden standard windows are distinguished by highair permeability. The incoming volume of oxygen through unconsolidated spaces and cracks is quite sufficient for a medium-sized house. Also consider the air flow provided by the doorways.
Airing the room due to the small opening of a plastic window or vent leads to the following problems:
