Ventilation in an apartment house - a variety of devices and circuit examples spreading room

Ventilation in an apartment house

The phrase "the struggle for the quality of life"perceived by most of us as a synonym for "the pursuit of material wealth." Meanwhile, the air quality in a residential area is much more important "status" of the elements of interior, fashion apparel and designer furniture. After a long and systematic exposure to low-quality (not in accordance with acceptable standards) air can cause deterioration of state of health, decreased performance and, alas, ill health. Admissible and optimal standards of air mobility, its temperature, humidity knowingly prescribed in technical regulations and rule books. According to the requirements of state standards, taking into account all the parameters of the premises, designed ventilation system in the panel house, a brick apartment buildings, any other apartment building. To ensure the necessary air exchange (removal of contaminated air and supply of fresh) is calculated and designed ventilation system. Let us consider how the ventilation system in an apartment building can be realized.

In addition to the placement of ductwork drawingsdiffusers, vent lines and other elements of the ventilation system, developed detailing ventilation equipment components, are calculated energy consumption and dimensions. ventilation device in the panel house, as well as in a brick should be thoughtful and efficient, because in addition to providing air, it is important to preserve the heat in the house in winter. In addition, properly furnished ventilation can prevent the spread of fire in the event of an emergency, that promotes the use of fire-resistant materials for installation, automatic safety valves.

Features of the ventilation system of choice

Selection of the ventilation system is made forconcrete building, this takes into account the number of storeys, building category, settlement level of traffic noise, air pollution degree. Organization of air flow through the ventilation channels, carried out in a natural way (due to the temperature and wind pressure drops) is recommended for premises located within neighborhoods, with traffic noise level not exceeding 50 dBA. Systems with positive motivation extract or supply is set to provide a comfortable environment in the buildings where the traffic noise from the facades exceed 50 dBA.

Types of ventilation systems for residential apartments

  • Ventilation is carried out naturally venting via thrust arises in ventilation ducts due to temperature differences and the influx of outside air through the vents and windows;
  • combined system with forced removal and natural airflow or, on the contrary - with mechanical injection of fresh air and natural removal;
  • fully mechanical as the removal of waste, and the injection of fresh air.

Inlet and outlet air in various ventilation systems

Supply of fresh air into the roomcarried out in different ways, it depends on the ventilation system. In the absence of preheating of the supply air flow needs to be produced in the upper zone to provide the best mixing with the heated room air. In systems where the supply air is heated radiators, air flows from the outside of the equipment or for them to ensure its heating. In systems with decentralized flow where air-heating is performed by means of heaters built-in air handling devices and air flow is produced in the upper or lower area of ​​the room. The air supply is carried out in the premises (children room, study, bedroom and living room). Exhaust air, regardless of the type of ventilation system, must be carried out from the top of the kitchen area, toilets and other ancillary facilities. The ventilation grilles should be located at a height of 2 m (or higher) from the floor.

Details of the ventilation schemes in an apartment house

The scheme of ventilation in an apartment house shouldbe made mandatory zoning for clean flow of polluted air from the ancillary facilities in residential should be deleted. It is advisable association exhaust ventilation shafts individual room units. ventilation systems with natural prompting inflow and output air to perform better separated (excluding prefabricated vertical or horizontal channels). Ventilation in a building can be arranged with joining ducts of different floors to a common (prefabricated) channel.

Joining a team of mine-channel satelliteIt must be made through one or more floors. Exhaust channels of the two upper floors should not be connected to a collection channel expedient separate abduction.

Depending on the scheme of the organization of airdistinguish ventilation and mixing ventilation air displacement. Air exchange with mixing characteristic of the premises with an airtight vapor barrier, concrete and brick buildings with airtight walls. And Ventilation and air extraction is carried out using a small vent windows, door and window slit openings are also taken into account.

Due to the high local air velocitystreams fresh and polluted air are mixed and effectively removed. So remove all the contaminants can not be, because there is always room area with practically zero velocity air movement. Only the right organization to achieve the desired effect can be the ventilation system.

Most often used in Europe before the systemventilation. It is carried out at the expense of the natural draft arising as a result of the temperature difference between indoor and outdoor air. The popularity of the system unit, in which the fresh air source is a gap in the window bindings and open windows is due to the low cost and simplicity of the device. In addition, natural ventilation with the influx of almost do not require additional maintenance.

Today, due to modern tightnesswindows, natural ventilation in the apartment building is ineffective. Only a few of us in the cold season will want to lose precious heat to provide the necessary air flow. However, even the depressurization of the apartment (opening vents) brings only an additional discomfort from increased noise levels (from the street), heat loss, but still does not provide the necessary air flow for efficient operation of ventilation. Gradually increases the humidity in the warm humid microclimate of apartments with air spёrtym created excellent conditions for the growth of mold and mildew that not palatable and unhealthy.

Device controlled system with a naturalinflux through the intake valves are possible not only to provide the necessary level of ventilation, but also reduce the noise penetrating into the apartment. Mechanical exhaust device (as well as a mechanical supply and exhaust) ventilation system can achieve normalization of air-thermal regime of apartments, which will give an opportunity to significantly reduce the cost of heat generation. air recovery (Recycle exhaust air heat) can achieve optimum microclimate preservation at low energy consumption.
