Ventilation in a residential building. Previously, ventilation was provided due to the flow of clean air through the cracks in the windows of wood. But in our time, the buildings are collected in plastic windows, which is characterized by great impermeability – here natural ventilation is not possible. And systematic ventilation of the premises does not always make it possible to resolve the issue of air cleaning. It is spectacular in winter, and in the summer, dust and various allergens fall from the street along with the air. All these problems can be solved using the design of air ventilation and air conditioning.
Note such ventilation options
1.Consolidated – natural exhaust ventilation in combination with mechanical supply.
Used in many houses. To do this, in the walls of the structure, the hood channels are laid separately for kitchens, bathrooms and showers. Ventilation will be made naturally or the device of natural exhaust ventilation will be supplemented by installation of fans, which are built in the inside of the ventilation exhaust ducts. In most cases, monoblock structures are used as an supply installation. Such products are equipped with automation. The superiority of the combination of mechanical and natural ventilation – it does not make it possible to enter the rooms for living unpleasant aromas. And minus – this kind of ventilation provides for the installation from below the doors of the outbuildings.
2.A supply and exhaust design with cooling of the air influx.
It is installed if the ventilation and cooling of air are needed, this is achieved by the installation of the chief air conditioner. In this case, the air filtration will be 100 percent. Its poor quality is the need to install a large number of ducts, installation of expensive automation and freezer machine.
3.Ventilation of the supply and exhaust type, providing for temperature adjustment.
The design of the main air conditioning is installed, guaranteeing the influx of clean air. The cooling of the premises to the required temperature is done using specialized “closers” – individual air conditioners, which makes it possible to configure the temperature separately in all rooms. To reduce the noise level, the supply ventilation in a private house is installed in the basement, and if there is no basement, then the supply devices are located on the ground floor in different utility rooms.
Basement ventilation
Ventilation in the house must be thought out in housing rooms, as well as in the basement, as it is distinguished by high moisture. In the variant of poorly organized ventilation of the cellar, there will be dampness and musty throughout the house. Here we need exhaust and supply ventilation, which always works. In most cases, to save hot electricity and water, supply and exhaust devices equipped with a heat recuperator are used to warm up supply air. This ventilation makes it possible to significantly save on electric energy.
Stages of work
You should install ventilation at the beginning of the repair. Before the installation work, you need to prepare the tools that you need, to calculate the ventilation of the exhaust first of all, the opening for the ventilation box is performed. The most beautiful thing is to place it very close to the floor level. For better ventilation, the fan should be installed in the ventilation shaft, and therefore the pipe must be round and a couple of centimeters wider than the fan itself. Having formed with the location of ventilation, you can start work: 1.Outline the center and contours of the upcoming hole so that it is a little more used by the pipe;
2.Holding horizontally a performer, but with a light tilt down, perform a hole;
3.With the help of a hammer and a chisel thoroughly get out a cut mother, then carefully clean the hole from the dust and dirt. Another stage – installation of the pipe. First of all, the fan should be installed inside the pipe. The fan is best to take more expensive, so that it serves for a very long time and works quietly: 1.Put the pipe along with the fan in the finished hole;
2.The cracks remaining between the wall and the pipe must be sealed with foam for installation. While the foam for installation work dries (at least 12 hours), we proceed to the electrics eyeliner: 1.Cut the contours of the strobes with a grinder;
2.Remove to remove the chipper;
3.Make a hole under the circuit breaker;
4.Install the box, and the switch is collected after the performance of all facilities;
5.Put the wire, noting it with the help of alabaster;
6.Combine the wire with the fan and the switch. It remains only to equip the appearance of the appearance of the ventilation: 1.The protruding remains of the foam after it dries cut off with a knife;
2.Speak the strokes and adjoining inside with ordinary plaster or putty, and from the outside facade;
3.Plastic grilles are installed on the 2nd sides of the ventilation pipe, and for fidelity to screw them with self-tapping screws. Similarly, in the framework of this article, we talked about ventilation – about its installation technology and the main views in a private house with our own hands. Try and you everything will work out.

Ventilation device
Forced
Forced ventilation with additional air purification (filtration) in most cases is arranged if the situation is very contaminated or the house is built of similar materials as:
Polistyle concrete foam:
3D, SIP, Sandwich, MDM, Sota panels.
This includes buildings built according to frame and technology from Canada, as well as know -how in the construction works of thermo – and isodoma.
Natural
Natural ventilation of a suitable when there is actually a clean atmosphere for houses built from:
wood (log, glued beam, ordinary bar);
blocks from gas – and foam concrete, as well as expanded clay;
brick;
Samana;
monolithic expanded clay concrete.
Mixed
If the house is equipped with natural ventilation, then to supplement it, an exhaust device can be installed, a similar technique and is called a mixed view. But, this is done, only in that option if with ordinary traction in the duct channels (there are no falls, clogged areas, etc. p.), the replacement of air in the premises is performed poorly.
Main! The individual use of exhaust devices in tightly hiding rooms, without aeration is inefficient, with poor circulation of masses of air, the installation of supply ventilation is required.
Product ventilation with your own hands. We select the device
Fact! None of the classic ventilation systems will work appropriately without admission to the room of clean air. In most cases, it enters through leaks in the doors and windows or open type of window. All this is so, but with the existence of hermetic double -glazed windows and good heat insulation, and also the absence of a gap, the tributary is not from where. Difficulty is solved simply arranged supply ventilation. It is very easy to install it with your own hands, the most basic form with the option of supplying air to the house.
Types of devices:
Support valves installation are done:
In the upper (deaf) part of the window block, the distribution of air flow begins with the ceiling area, where it is mixed with a warm atmosphere of the room and is divided through the room;
Under the windowsill, heating the incoming masses of the air with a heating radiator is supplied;
on the top of the wall, side by side with the window is like 1 point.
The heat exchangers, the working principle is based on the difference between the temperatures in the room and on the street, are able to additionally be supplied with different filters, they are distinguishable, according to:
the flow of the flow is direct -flow, anti -flow;
The structures are plate, tubular, walnut, ribbed, rotary. In private housing construction, rotary and plate installations are mainly used.
Advice! When using rotary recuperators, carefully look at the presence of a soundproof casing in the set of a soundproof casing, which significantly lowers the noise from the working device.
Calculation
Number, purpose, height of the premises, multiplicity (volume and frequency) of air exchange and number of residents are very important conditions when installing ventilation. According to these indicators, a calculation is made: cross -section, length, location and number of air ducts, as well as presence/exhaust). Installation of pipes (boxes) must be started from below and drive up, from the lower floor to exit to the roof. Installation. Its start should be located under the basement ceiling and rises throughout the height of the structure with access to the roof. Its lower part is equipped with a crane and a capacitor to remove humidity. The minimum allowed pipe height above the skate 30 cm. All sections of the pipe located outside the house are subject to compulsory insulation. The supply pipe. It begins above the floor level (4050 cm) and is excreted through the base, to the street. Its external part is obliged to be 1.5 m from the soil.
Ventilation shaft in a private house
Ventilation shaft in a private house Uniqueness. Often we learned to see them in the city dwelling. But, if the house under construction has a large number of storeys (from 2 floors), then it makes sense to think about its device. This becomes a guarantee of the same distribution of fresh air into all available rooms, regardless of the temperature on the street, direction and wind strength, and the presence or absence of mounted fans. Types of mines: 1. The barrel is vertically located, passing completely through the structure.2. Air sleeve ordinary duct. Mother for the walls of the ventilation mine: 1. Stainless steel.2. Brick masonry.3. Galled tin. The mine in the house is put strictly vertically. Outlets (holes) are removed from the premises and utility rooms in it. The lower point of the shaft is obliged to begin a little below the ceiling of the lower floor (50 cm), and the largest rise above a fairly high part of the roof is not less than a meter, this will give the perfect retraction rate of street air. When installing a ventilation shaft, there is one requirement, which slightly reduces the planning of the structure of all rooms with high moisture should be around the duct. Due to the similar placement and very low temperature of the shaft walls, when compared with the walls and internal partitions of the house, it is recommended to organize an additional wall thermal insulation, coping with mine.
