How to make a hood in a private house? How to make a private house ventilation system

The installation of a ventilation system in a private house can significantly improve the microclimate in the premises. In the assembly, these structures are not too complicated and, if desired, can be mounted with their own hands. On the features of the technology for doing this work, as well as on how to draw a hood in a private house, and talk later in the article.

Types of ventilation systems

At the moment, in country houses, only two main types of such structures are used:

• Natural ventilation. In this case, only the riser is installed. Inflow of the same air is carried out through the windows, cracks in the windows, or specially made holes behind the heating radiators. The disadvantage of such systems is, first of all, a very low efficiency. In addition, in summer such a design generally does not work at all because of the lack of temperature difference in the street and inside the house.
• Forced ventilation. In this case, the discharge of polluted air is carried out with the help of special fans. An air supply duct is also installed, supplying air from the street.

Kitchen hoods are usually attached to the existing system of forced ventilation. In its absence, the conclusion is made either to the mine of natural extraction, or directly to the street.

Installation of natural ventilation

The assembly of such a system reduces mainly to the installation of a riser. The upper part of it should protrude beyond the roof. Usually, as in urban flats, the bends from it are made to the kitchen and to the toilet. In order to ensure the influx of fresh air into the apartment, under the heating radiators in this case, drilled holes of 8-10 cm in diameter. Special inlet valves are inserted in them.

Ventilation in a private house, and how to properly make a ventilation system

In a suburban structure can be installed as a conventional design with air ducts and fans, and more modern, expensive and comfortable - with a recuperator. As for the complexity of the installation, for both systems it is approximately the same. Only in the first case air is taken directly to the street and from here it is taken away. In the second, both flows pass through the recuperator. The latter is a device designed to collect heat from the exhaust air and transfer it to the supply air. Thus, ventilation systems with a recuperator allow you to save on heating.

Types of kitchen hoods by the principle of action

Before you start to understand how to make a hood in a private house, let's see what kinds of such devices are being produced at the moment. To subdivide the structures intended for air removal from a plate, it is possible on three basic groups:

• Exhausting. This is a classic version, designed to remove contaminated air from the cooker to the ventilation shaft or to the street.
• Recycling. To make a hood in a private house of this type means to get a fairly efficient and reliable device. Such designs, in fact, are large air purifiers equipped with a filter system. Their main advantages are simplicity and cheap installation. Disadvantage - the need for periodic (usually every six months) filter replacement.
• Combined. These hoods can both draw air to the street and clean it.

How to choose a vent

A little later, we'll figure out how to make a hood in the house. The hood in a private house is usually attached to the main ventilation system. So first we'll find out how these structures are mounted. Pipes for such systems can have a circular or square cross-section. In addition, their diameter can differ. Both metallic and plastic versions of air ducts are available. The first are characterized by maximum longevity, the latter - light weight and ease of installation. Special mention should be made of the recently appeared flexible corrugated air ducts.

Which recuperator is better?

Many owners of holiday homes are interested in the question of whether it is possible to make ventilation of a private house with their own hands. Of course, you can, including with the recuperator. The main thing is to choose the right thing, actually, this very device. At the moment, the most popular variety are lamellar structures. The ejected and supply air in them do not intersect directly with each other. Contact occurs through plates made of plastic or aluminum foil. The merits of such devices can be attributed primarily to the simplicity of design, reliability and maintainability. To disadvantages is the possibility of icing of plates during the winter period of time.

Drafting of the project

So, let's begin to understand how to properly make the ventilation system of a private house by yourself a forced type. Of course, before starting its installation, you should draw a layout diagram. The development of the project is best entrusted to specialists. This case is very responsible and quite complex. When you perform it, you need to take into account a lot of nuances. If the project is incorrectly drafted, the ventilation will not work effectively. In addition, such a nuisance as the appearance of the smell of a toilet or kitchen in the living rooms is possible.

Recuperator installation

The device for exchanging heat between air flows is usually installed in the attic or in the basement. The main rule to be observed is the flatness and absolute horizontality of the stand.

Place the recuperator in an easily accessible place. The fact that the owners of the house in any case have at least two times a year to clean his plate of dirt.

Installation of main air ducts

Preliminary in the walls are drilled holes for the extraction and intake of air. Then they insert special branches equipped with valves. Then proceed to install the main (supply and exhaust) ducts. Mount them can be to the walls behind gypsum board or plywood trim or behind stretch ceilings. Sometimes they are carried out in interstorey floors. However, the inconvenience of this method lies in the inaccessibility of the elements in case of need for repair.

Fastening of pipes is made on special collars. For plastic lungs, one will be enough for a single piece. The pitch between the metal clamps is usually about 1.5 meters. At one end, the main pipes are connected to the branch pipes in the walls, the second - to the corresponding branch pipes of the recuperator. In the instructions accompanying this device, the manufacturer indicates how to connect the air ducts.

Piping the rooms

Proper piping through the rooms is also an important answer to the question of how to make a hood in a private house. House installation of the hood is made with the connection of its duct to one of the branches heading to the kitchen. To the main highways it will be necessary to attach segments leading to rooms that need ventilation. They are connected through special branch pipes and tees. In each room must be withdrawn as an exhaust duct, and supply air. The first is better to install at the ceiling, the second - on the floor or at the bottom of the wall, closer to the radiator. In the holes made in the construction of the house, pipes are inserted with adapters, on which the ducts are fixed. On top, they are covered with decorative bars.

Kitchen hood in a private house: installation instructions

Mount this device on a wall or furniture, depending on the design. According to the regulations, the distance from it to the plate must be at least 65 cm for gas and at least 45 cm for electric. The air duct from the hood is fixed to the grate of the exhaust pipe or shaft. If there is no ventilation in the house, a hole is made in the wall under the air duct. In the latter case, it will be necessary to ensure fresh air to the kitchen. For this, as with the device of natural ventilation, under the windows or behind the radiators of heating, it is necessary to drill the holes and insert the inlet valves in them, which you can buy in the building supermarket.

How to choose an exhaust duct

Thus, we briefly examined the issue of how to make a hood in the house. Extraction in a private house will work effectively only with the correct selection of ducts. At the moment, only two main types of corrugations are produced for such kitchen appliances - plastic and metal. The first are already cut into pieces in the production process. In the event that the exhaust hole is in the opposite wall from the plate, one such segment may not be enough. But joints in the ducts of kitchen hoods are extremely undesirable. Therefore, in this case it is better to purchase metal corrugation. In the event that joints for any reason can not be avoided, they must necessarily be glued with a sealant. Hide corrugation under a decorative box, which can have a round, rectangular or square shape. Joints in it should also be sealed.

How to properly attach the recirculation hood

To make a hood in a private house is also to correctly mount the case of the device. Install it on the wall should be strictly on the markup. For this, a horizontal line is drawn in advance with a pencil. Next, two holes are drilled on it, coinciding with the brackets on the hood. Then dowels are driven into the holes. They are attached and screwed with screws. They hang a device on them.

Mounting of dome devices

How to draw a hood in a private house using a dome construction - the question is also not too complicated. As in the first case, a markup is preliminarily made for this variety. Devices of this type are attached to the wall directly on the body. As fixing elements, dowels and screws are used. Under them on the markings in the wall holes are drilled.

What rules should I follow when installing?

So, how to draw a hood in a private house, we have found out. When installing it, the following points should be considered:

• Plan the location of the device so that the duct is as short as possible.
• The number of knees should be minimized.
• If the ducts can not be avoided, you should try to make them not too steep.
• Acquire the air duct with a smooth inner surface, in order to reduce the flow resistance to a minimum.

So, we have figured out how to make hoods and ventilation in a private house. As you can see, business is not particularly difficult. The most important thing is to develop the right project. This will make living in the house as comfortable as possible in summer and in winter.
