Ventilation in the apartment with his hands or 4 different ways to provide air circulation

"It is necessary as air" - we're talking about somethingparamount to emphasize the special status of obvious value vital. Saying something we say, that's just for the everyday concerns the importance of fresh air to enter imperceptibly otdvigaetsya sidelined. The desire to improve the interior of their home finds a way to install brand new sealed insulating glass units. Striving for rational spending motivates us as among the variety of options for the entrance doors we choose the least susceptible to temperature and humidity changes, tight to the steel box. Open a window for ventilation in the cold season, we also typically not in a hurry, trying to retain valuable heat. At first glance, nothing wrong or unusual in the above does not. Here are the most common jet ventilation in the apartment is only provided that the free overflow of air from all living areas, with the obligatory fresh influx. Consider now in detail feature modern apartment ventilation device, learn how to achieve compliance with air to find a response to the main question of whether effective ventilation can be arranged in a flat with their hands.

Consider the above above averageapartment as a single volume of air is not possible (each room has its own degree of pollution, air exchange prevent the tightly closed windows and doors). It turns out as a result of the extremely unhealthy atmosphere, under such circumstances of supply and exhaust ventilation for apartments (most often used in urban high-rise buildings) is ineffective, if not dangerous. Excess heat, and even in combination with high humidity and low air mobility favor the growth of pathogenic fungi and mold. Consider now how should be organized in the ventilation system in the apartment.

Getting acquainted with the mechanism of work of normal ventilation

Residents of urban high-rise buildings do not even beforeI thought about how to make the ventilation in the apartment. Of course, understanding that in any room should be a continuous exchange of air (supply of fresh and the removal of contaminated air) were present, but we all had enough understanding that the ventilation in the apartment kitchen and bathroom arranged thoughtfully: through the exhaust channels are removing exhaust air. Admission is done by infiltration of outside air through the open window or leakage of windows and doors. Indeed, while a system of natural ventilation itself completely justified. Today, the lack of effectiveness of this method (of the reasons we have mentioned above) require the installation of additional devices. Forced ventilation in the apartment will be effective only if the correct equipment selection (selection is made on the basis of calculations of air).

Define standards of air

To determine the required amount of fresh airAir is simple: it is enough proportioned known ventilation standards in the apartment with an area of ​​the premises and the number of residents. Thus each square meter requires breathability 3 m3 / h and per adult human of 30 m3 / h. Based on these standards, it is easy to calculate the air exchange for each case and develop a ventilation project apartment, picking the most profitable way and the required equipment.

ventilation device in the apartment mayperformed using thrust arising due to the temperature difference between indoor and outdoor air (this method is called natural convection), or by means of the thrust exercised by mechanical means. Forced ventilation may be fresh air, exhaust and air handling.

The principle of natural circulation of air

The easiest way to room ventilation, ifwhere air removal is a natural draft through the ventilation channels, and inflow through the open windows, leaks in the windows or special blowing device is called a "natural ventilation" before it's too prevalent today are often ineffective because of the lack of much-needed leaks. However, the air flow can be accomplished by air inlets which are built into walls or windows. An example of such a device is a supply adjustment valve mounted on the window sash.

Install supply valve does not reduce the sound-insulating properties and does not spoil the appearance of the window

Thanks to a reflecting visor devicepractically does not reduce the quality of sound-proof windows. Valve Installation takes less than 15 minutes. Similar in principle to the device can be installed in the wall near the radiator. This requires a hole in the wall with a diameter from 50 to 100 mm (depending on the valve model). The definite advantage of such models in the device and ease future maintenance. The efficiency of the air-supply valve depends on the serviceability of the exhaust ducts. Natural ventilation is most effective in winter, when large temperature difference, providing a natural draft. In summer, when the temperature difference is less than 15 ° C, this craving unobtrusive.

The device Forced ventilation

Installation of compulsory ventilationIt involves the removal of exhaust air by mechanical means. To do this, use fans, built-in ventilation shaft in the bathroom and electric cooker hoods. With fans in the apartment air creates negative pressure, impelling sucked from the outside through the intake valves or open windows. In the cold season, it is desirable to provide for heating the fresh air, to this end can be installed blowing device with built-in electric heaters. When using such devices without heating them should be placed over the heating devices.

A method of forced-air supply

The main feature of the functioning of forcedVentilation is forced feed outside air (through the established air inlets) and the removal of contaminated natural draft through the ventilation shafts in the bathroom and kitchen. Air handling units come in different models and configurations, but the principle diagram of the device, as a rule, all the same (fan, air filter, shutoff valve, heater, shumootrazhatel).

A device for heating the supply air

fresh air heating in winter to prevent condensation and mold in the supply device

In this case, installation of ventilation in the apartmentIt requires opening the equipment in main wall (diameter depends on the model) and the connection to the power supply installation. This setup is almost silent in operation, it gives an opportunity to provide a clean room, hot-air, regardless of season and weather conditions. To facilitate the functioning of the system in the interior doors must be undercut below 1.5-2 cm or embedded grid.

Ventilation - the advantages

fully mechanized Under this system, allapartment ventilation process: inflow and venting occurs by force. Mechanical supply and exhaust ventilation in the apartment - this is the most convenient and modern way. Indeed, in addition to warm and purify the indoor air flow, it can also use the device with heat recovery, which will reduce heat loss up to 70-80%. There is a possibility of installation of such equipment in suspended ceilings or back rooms.

Supply and exhaust air unit with heat recovery allows you to return to the room exhaust air heat

The use of air handling devicesrecovery during the summer will reduce the load on the air conditioning, and in winter will keep warm the house during ventilation. So, HVAC apartments, selected taking into account the specificities of each system running smoothly, providing a comfortable environment with low energy consumption. Installation of ventilation in the apartment could easily be made with your own hands, just take some diligence in the detailed study of the issue.
