phrase "struggle for quality of life" is perceived by most of us as a synonym for "the pursuit of material wealth."Meanwhile, the air quality in a residential area where the most important "status" of the elements of the interior, fashion apparel and designer furniture.After a long and systematic effects of low-quality (not in accordance with acceptable standards) air can cause a deterioration of health, decreased performance and, alas, ill health.Valid standards and optimal mobility air, 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 required ventilation (removal of contaminated air and fresh) is calculated and designed ventilation system.Let us consider, as it may be implemented ventilation system in an apartment building.
addition to drawings of accommodationair ducts, diffusers, vent lines and other elements of the ventilation system, developed detailing nodes ventilation equipment, are calculated consumption and dimensions.Ventilation device in the panel house, as well as in the brick should be thoughtful and efficient, because in addition to providing ventilation, it is important to preserve the heat in the house in winter.In addition, properly invested in ventilation can prevent the spread of fire in case of an emergency, that promotes the use of fire-resistant materials for installation, automatic safety valves.
Features selection of the ventilation system ↑
Selecting the ventilation system is made for a particular building, this takes into account the number of storeys, the category of building settlement level of traffic noise, the degree of air pollution.Organization of air flow through the ventilation channels, carried out in a natural way (due to temperature and wind pressure drops) is recommended for premises located within the blocks, with the level of traffic noise does not exceed 50 dBA.Systems with positive motivation extract or supply is set to provide a comfortable environment in the buildings where the level of traffic noise at the facades of more than 50 dBA.
Types of ventilation systems for residential apartments ↑
- ventilation, provide natural air removal using traction arisingin ventilation ducts due to temperature differences and the influx of outside air through the vents and windows;
- combined system of 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 injection of fresh air.
inlet and outlet air in various ventilation systems ↑
supply of fresh air in the room is carried out in different ways, it depends on the ventilation system.In the absence of preheating of the supply air inflow it is necessary to make the upper area to provide the best mix with the heated air in the room.In systems where the supply air is heated radiators, air flows from the outside of the devices, or for them to ensure its heating.In systems with decentralized flow where air is heated by means of heaters built-in supply unit, the flow of air is produced at the top or bottom area of the room.The air supply is carried out in residential areas (children's room, office, bedroom and living room).
Exhaust air, regardless of the type of ventilation system, must be carried out from the upper zone of kitchens, toilets and other ancillary facilities.Ventilation grilles should be located at a height of 2 m (or more) from the floor.
Details of the schemes of ventilation in the apartment building ↑
ventilation system in an apartment building should be made mandatory zoning for clean flow of polluted air from the auxiliary premises in residential necessarydeleted.
feasibility of combining 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 the total (prefabricated) channel.
Joining a team of mine-channel satellites must be made through one or more floors.Exhaust duct two upper floors should not be connected to a collection channel expedient to separate leads.
Depending on the scheme of the organization of air ventilation to distinguish between mixing and displacement ventilation air.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 ventilation window, slit door and window openings are also taken into account.
Due to the high local rate of air flow of 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 correct organization of the ventilation system can achieve the desired effect.
most commonly used in Russia before the system ventilation.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 device system in which a source of fresh air 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 the tightness of modern windows, 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) only brings additional discomfort from increased noise (from the street), heat loss, but still does not provide the necessary air flow for efficient operation of ventilation.Unnoticed increased moisture in the warm humid microclimate spёrtym apartments with air create perfect conditions for the growth of mold and mildew that not palatable and unhealthy.
Device controlled system with a natural inflow 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 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 recuperation (heat recovery exhaust air) can achieve optimum microclimate while preserving low energy consumption.
