Driving movement of air in the building with natural ventilation

Forced ventilation system can be of several types. These include a simple window design of the valve, which is mounted on top of the frame plastic window and provides fresh air penetration. Another device is a blower motor. It is installed in the window opening or into the prepared hole of the wall. These elementary ventilation units have a number of drawbacks:

  • air entering the dwelling, is not cleared, that is set when the windows are located on the outside (the roadway) of the street;
  • in the winter the air flow has a lower temperature, which may adversely affect health;
  • humid air penetrates into the room, can promote damage furniture (swelling or cracking), and peeling the wallpaper straight.

Ventilation air heating

One type of air-supply plant is forced ventilation with heat recovery system. It allows to heat the incoming air stream by the heat of air removed from the room, it saves energy. Much of outdoor air flow is heated by a heater. heat recovery ventilation system provided with a heat exchanger connected to the supply and exhaust air ducts.

air is displaced out of the room by moving through the recovery device, transmits heat incoming air flow. In this process the air flows (incoming and outgoing) are not mixed. By ventilation with heat recovery is possible to effectively reduce the cost of heating the feed stream in the cold season. And in the warm season, when functioning in the room air conditioning a ventilation system by a warm recovery incoming stream is cooled to the desired temperature.

Ventilation air heated may be provided with an electric or steam heater. For ventilation of homes, large offices, warehouses often use water heaters, as especially urgent issue for energy efficiency.

Ventilation air from a heated automatic control, which is performed by the remote console. Installation of the system with their own hands is associated with precise calculations, so it is best left to professionals.

Management of fresh air ventilation

Is controlled by a separate control. Regulated the feed rate of fresh air (five-speed setting), the outlet air temperature, has a timer.

Automatic settings allow you to synchronize the on / supply fan off. There is a protection system that provides emergency shutdown. fan motor winding is provided with a thermal protection (protection operation when automatic shut off fan). Heater with a built-in thermostat ensures protection from overheating or fire.

Ventilation installation complement pressure gauge that measures the air pressure difference of the filter and at the site where ventilation valve is installed. For example, during a forced stop system automatically stops flow of outside air into the room. Furthermore, the pressure difference may grow depending on the dirtiness. Once the limit of the filter contamination exceeds the permissible rate, the system will notify the need for its replacement (or cleaning). This can be done by hand. The budget proposed to supply air just fixing reference Filter Time.

Valve ventilation

One type of channel-free ventilation is ventilation valve. The function of it is that it misses the outside air into the house without opening the air vents and windows, eliminating dust and noise from the street. The apparatus helps normalize humidity.

Installation of the valve supply with their own hands is quite simple. The valve is installed in a pre-drilled hole in the wall above the radiator. Cool air is heated by batteries, So it is always warm in the room. The wall flap is provided with a coarse filter shumopoglotitlem and air purification. The valve flap is produced by using a regulated amount of feed air.

Air heating fresh air ventilation

One of the modern and the main types of advanced heating - air heating. The possibility of such heating enables the combination of space heating ventilation and air-conditioning. In the cold season, the warm air is supplied through the same duct system, which forms the cold air in hot weather. This is the versatility and efficiency of air heating, which can be applied in a residential home or office.

Air heating functions due to supply air to a radiator, which is heated by the district heating water system.

The system design of ventilation

The system design of ventilation

Air heating automation system is provided, which itself controls the supply of the required amount of heat. It is possible to set to Eco mode the heating system (for example, when the house is unoccupied, it is possible to reduce the minimum temperature). In case of return to the normal heating mode, heated rooms of the house quickly.

Useful advice!Calculation and design of heating ventilation is based on consideration of all design features and technical parameters of the parts making up the ventilation system. The exact calculation and proper installation guarantee trouble-free operation of the air-supply plant.

Producing in-house assembly and installation of heating ventilation with his own hands, it must be remembered that the calculation of ventilation values ​​is quite complex and specific. It is worth prokonsultirovatcya with specialists in this field.

Calculation of ventilation

Calculation of ventilation for the house is made taking into account the purpose of premises, as different rooms in the house has its own microclimate. It would be logical if the ventilation calculation will produce professionals. Getting to the calculation of the air with his hands, you must first of all take into account the capacity of the system, the configuration for each room, heat recovery, automatic control.

Calculation of ventilation of the house is a specialist

Calculation of ventilation of the house is a specialist

The calculation of ventilation, consider the following:

  • utility buildings (villa, apartment, floor area, the number, the humidity being of people);
  • make calculation circuit duct sections;
  • breathability (calculation can be done using a table drawn up according to the standards);
type of lodging Temperature (calculated) during the cold season (° C) The volume of air displaced from the room (m³ per hour) in the area of ​​1m²

Useful advice! It should be understood that even a slight error in the calculation may result in a decrease in efficiency of the ventilation system and unnecessarily increase power consumption.

  • develop a plan, including all charts and calculations;
  • coordinate the project by the competent authorities;
  • install ventilation for the house with his own hands.

Ventilation systems are an important element in the construction of industrial buildings, offices and residential houses, as their quality is directly related to the functioning of the health of the people who are in them.
