Device and installation of supply and exhaust ventilation in a private house

Modern technologies allow to build a reliable, comfortable and sealed private house. Everyone wants to reduce the level of heat loss, only this can worsen the natural air exchange in the house. To avoid this, it is necessary to create a competent ventilation scheme, which is usually designed during the construction of the building. Of course, it is possible to equip an already finished house. Useful ventilation system will be for older buildings.

You can use different systems, and yet the most effective is supply and exhaust. In this case, the device of this ventilation is not the same for different rooms, but the main components remain common. There are also options for the complexity of the configuration. But in order to ensure good ventilation, you should take into account the special characteristics of not only the equipment itself, but also the building as a whole.

There are circumstances that do not allow the choice of a not very efficient air exchange pattern, this is at least inexpedient. For example, when there is polluted air outside the window, dust, unpleasant smoke and exhaust fumes from vehicles get into the house. Existing filtering methods here will not be very effective. Forced-air exhaust systems of the mechanical type will be an ideal option, especially if the ventilation must be installed in a wooden house.

Thanks to this ventilation system, clean fresh air will spread through the rooms. Gases with dust are delayed by multistep cleaning, so foreign odor will not get into the room. Supply and exhaust systems provide excellent circulation. Unpleasant smells will instantly be eliminated from the toilet and kitchen room, without having time to spread into the rooms of the house.

Today there is a type-setting and monoblock type of supply and exhaust systems. Ventilation equipment can consist of a single solid body, and when installing such a ventilation system, it is not necessary to perform complexwork. The installation is simply mounted on the wall, and then the duct and the necessary power supply are connected. At the same time, the cost of ventilation is several times higher than the price of a type-setting system.

For picking by independent forces, they usually choose special fans, that is, one is installed for the intake, the other - for the removal of exhaust air. You can choose a channel, axial, with a valve or a centrifugal model. This device will create the right direction flow.

According to the design of the ventilation system can be divided into two separate groups, that is, an independent type of device with the emission of exhaust air and the installation with special reception channels. All components of the air ducts are connected by shaped elements. Mostly plastic pipes are used or mines are used, the construction of which was provided for in the house in advance. These mines are usually located within the walls of a house. By the way, with their help, the internal air distribution is performed.

Consider the basic components required.

• The lattices intended for an air intake. They will prevent the penetration of a variety of third-party items.inside the ventilation duct.
• Filter designed to trap third-party unpleasant odors, insects and dust.
• A special type of valve designed to regulate the incoming volume of all outside air.

In fact, it is not so easy to make a competent scheme for the house on your own. In addition to the living rooms, there are also auxiliary rooms in the private house - a sauna with a cellar, a garage with a basement, and others. Each such room has its own humidity and temperature, therefore it is necessary to create a single ventilation system to take into account the requirements for each of the rooms. Important rules should be followed.

• Air masses should be directed from living rooms to utility rooms.
• Ventilation power should be sufficient for the area of ​​the whole house.
• Take into account the need and seasonal temperature fluctuations. For this purpose, equipment is used for cooling, heating of air masses.
• Provision should be made for remote and manual control.

Supply and exhaust type of ventilation for private houses is performed according to a special scheme. There are two types of such schemes.

• In the first case, the fan and duct, installed under the ceiling itself for the fence, serve to further remove the exhaust air.
• The second method of installing the ventilation system implies the location of the supply air just above the floor, and the output flow in the meantime should be located right at the ceiling. Then the air will be taken forcibly, then it is thrown naturally out.

Ensuring reliable ventilation of your own home with self-installation is possible. The owner of the house can choose one of the options that will allow to take into account the existing features of the building and financial possibilities.
