Features of the cellar ventilation in the garage. How to organize high-quality ventilation system

The article will tell you which hood in the garage will be more profitable. Buying a car, it is important to provide him with the right care, which will maximize its life. After reading the article, you can understand the various options for hoods and choose for themselves the most suitable of them.

1. Why do you need ventilation in the garage

If it is provided at the proper level, you can do the following:

• Make the air cleaner by removing from it is harmful impurities associated with the operation of the motor vehicle. Many drivers spend considerable time doing their car repairs. Sometimes in the process of work it is necessary to turn on the motor. With proper exhaust, exhaust gases will be quickly removed from the premises.

• A garage is often used not only for vehicles. Sometimes there may, for example, store vegetables. Increased humidity may cause damage to the air. High-quality hood will help solve this problem.

• Sometimes moisture can get into the room due to rain or snow. Proper ventilation will help remove excess moisture inside.

• Sometimes it can form on a car or on walls condensate that has a devastating effect. Regular intake of fresh air will help prevent its formation.

• Humidity has a destructive effect not only on metal parts. In such conditions, fungus can be formed. It may be on the walls or, for example, on vegetables that some may store in the garage.

Suitable for breathing air, the absence of excessive humidity, a regular flow of fresh air will create in the garage not only a useful, but also a pleasant microclimate.

1. Principles of operation of ventilation

In practice, various ventilation options can be applied. They can be divided conditionally on the basis of what principle of action is applied in each case.

Efficiency depends on the quality of the insulation and waterproofing of the garage. If the walls or roof let through moisture, the hood may not cope with this.

1. Natural ventilation

It is possible to try to solve the existing problem with minimal effort. This option is the most common.

On our site you can familiarize yourself with the most popular projects of garages and other "small forms" for private house - from construction companies presented at the exhibition "Low-Rise Country".

In this case, two vents will be needed. One is at the bottom, near the ground. The other is under the ceiling. The most suitable hole diameter can be obtained by simple calculations. One of the variants of such a calculation says that for every square meter of garage area there are 2 centimeters of pipe diameter. That is, if its area is 6 square meters. meters, the pipe should have a diameter of 12 centimeters.

The principle of operation is based on the fact that the room temperature is usually higher than outside. Relatively cold air enters the interior, which then warms up and exits through the hole under the ceiling. Fresh air comes in from the outside.

The most typical garages are 6 meters long and 3 meters wide. In this case, the diameter of each of the holes will be 27 centimeters.

Installation Features:

• You can use two, but smaller ones instead of one lower one. In this case, their diameter should be 70% of the original size.

• Vents should be located at a height of 10 to 15 centimeters from the floor level in the garage.

• On the other side under the ceiling is done pipe outlet. The latter is displayed upwards, and the higher it is, the better the ventilation will work. It is believed that the minimum height can not be less than half a meter.

• The gaps should be sealed with a sealant, the lower holes should be closed with a grid, and the upper edge of the pipe should be protected with a special tip that prevents precipitation from entering.

It must be remembered that although natural ventilation is much cheaper, the quality of its work does not always remain satisfactory. For example, in warm weather there will be practically no air flow.

It is necessary to take into account that when air is released to the outside, condensate will form in the pipe. If nothing is done, it will accumulate and flow down. To avoid this, it must be regularly removed, for which a separate tank is usually installed.

As a result, due to the low efficiency that natural ventilation has in a garage with a basement, it makes sense to consider purchasing quality equipment. Although the money at the same time will leave more, but in the end the hood will provide high-quality ventilation in any weather.

Forced ventilation

In this case, the exhaust operation will be significantly improved. When using this option, it is not necessary to take care of determining the correct size of the air vent. Here the air flow is forced and the supply of a sufficient amount of it is provided by the operation of the motor.

This option has important features to consider:

1. This is a relatively expensive option.

2. Electricity is needed to operate such a system. For this you need to connect the garage to the power supply.

3. In this case, the air moves with the help of fans. However, they can be installed on the "pushing" of air into the street, and in the suction of fresh air into the garage.

4. Noise is produced when the system is running.

5. There are a large number of parts here, and therefore, it is more likely that the hood in the basement of the garage will require repair.

In winter time, you can additionally ensure the heating of the incoming air.

1. Combined option

There is an intermediate option that allows you to use positive features in your design both ways.

There are two options for combined ventilation:

1. The ventilation system is designed so that it can operate in a “natural” mode as long as the weather permits. If necessary, the injection fan is already switched on.

2. The blowing fan runs all the time, but it only does half the work - helping with natural ventilation. For example, the flow of air occurs without the use of a fan, and the pushing out to the outside occurs already with its help.

It is important to note that the quality of work is not related to one or another location of the inlet or outlet. The only thing that should be avoided is the location of the holes opposite each other. In this case, a steady flow of air between the holes will occur.

Clearly, the ventilation in the basement of the garage is shown in the following video:

1. Ventilation of the garage under the house

The garages may be located separately, and in some cases they are located in the basement of a residential house. Then the ventilation of the cellar in the garage is of particular importance.

At the same time, the general principles remain the same, but the implementation scheme differs significantly:

• The inlet, when viewed from outside the house, is still located on the very surface of the earth. From it begins the pipe, which runs into the building and goes vertically down. In the garage hole is located next to the floor.

• Proper ventilation in a garage with a basement is done as follows. Hood begins under the ceiling of an underground garage and goes straight up, reaching the roof. It is considered. That it should go up above the roof to a height of at least 50 centimeters.

• There is a faucet in the bottom of the hood to drain condensate that has formed inside the pipe.

• The ventilation device in the basement of the garage is made in such a way that the external pipe outlets must be protected from rain or snow.

• The external exit of the inlet pipe is covered with a grill from insects and small animals.

It is unacceptable that the diameter of the pipe varies throughout its length.

1. What to do if there is a metal garage

Many use garages made in the form of a metal box. To ventilate them, consider the following:

1. They do not have an inspection pit, so there is no need to ventilate the underground part.

2. The garage is made of metal, so moisture and condensation threaten not only the car, but also the garage itself.

3. There is no heating. Therefore, most of the year there are sudden changes in temperature, contributing to the formation of condensate.

4. There is no connection to the power grid, so it is not possible to install a forced ventilation system.

Therefore, in this case, two rectangular holes are made, each covered with gratings in the front and rear parts of the garage under the roof. This will provide airing.

Additionally, it is recommended to warm the floor (put linoleum, concrete, put another linoleum layer). Such a floor will somewhat reduce the temperature fluctuations inside the garage.

1. Garage with underground part

When purchasing a garage, the driver usually wants to have a viewing pit in it. Ventilation is also required for this underground part. Usually when installing it, the focus is on the bottom.

The inlet pipe at the same time should extend near the floor of the garage itself. A pipe is also installed, one hole of which is located near the floor of the observation pit, and the other - near the floor of the garage. The outlet pipe is located at the top of the viewing pit.

1. Is it necessary to buy forced ventilation

Suppose you have previously installed the simplest hood. This is the reason why it is possible to determine whether her work is comfortable with:

1. In the room, the air is always stale.

2. On the walls regularly appear stains from dry condensate.

3. A fungus or mold has appeared.

First, you can take steps to improve the efficiency of the hood. This can be achieved using one of the following methods:

1. Make the diameter of the ventilation pipes larger.

2. Make it so that the external opening of the outlet pipe is higher than before.

3. Additional inlet and exhaust pipes can be made.

4. If there is a power connection, put a fan to improve air circulation. It is often enough to install it on a chimney.

If this does not help, it makes sense to think about purchasing a quality forced ventilation system, provided that it is possible to provide it with power supply.
