An extractor hood mounted in the cellar of the garage is necessary and this is obvious to every zealous owner. Some people realize that condensation due to temperature differences during the cold season harms the storage of vegetables and other supplies. Others understand that the imbalance of the microclimate with the formation of water vapor negatively affects the life of the car or installed equipment. Therefore, one way or another - everyone in the garage with a basement does an exhaust hood.
Hood design schemes
The basement hood in the garage is created on the basis of three different principles, namely:
- natural air circulation;
- a supply and exhaust system is mounted in the cellar of the garage, using the principle of increasing the air flow by natural and, let's say, not costly methods;
- To create the supply and exhaust ventilation of the cellar of the garage, complex technical solutions are applied that are fully automated.
Each garage owner makes his own decision based on the size of the building and the level of humidity that occurs in the cellar in the winter.
Today, the industry offers many mechanical and electronic-mechanical solutions for organizing supply and exhaust ventilation of the basement of the garage. However, their cost is quite high and therefore the use is justified only in buildings of really large size, as well as where the ceiling height of the garage is more than three meters.
Natural circulation hood
The simplest hood for the basement in the garage is based on the natural circulation of air under the influence of temperature differences outside and inside. Such a system is created quite simply, which the following schemes clearly demonstrate.
-
- Scheme 1
-
- Scheme 2
-
- Scheme 3
The hood is mounted in several stages:
- an air supply pipe is installed, one of the ends of which is located outside the garage, and the other in the cellar. In this case, both points should be as close as possible to the ground and basement floor;
- the exhaust pipe is mounted vertically, one end extends half a meter above the highest point of the roof. The second is located in the cellar, while its end is under the ceiling.
Such a hood in the garage works very simply. Warm ground maintains a relatively high basement temperature. Through the feed pipe, cold outside air enters the space and ends up in the cellar. There it heats up and exits through the chimney due to the temperature difference between the outside air and the one in the basement.
Such a hood is easy to install, you can use sewer pipes of large diameter, which are durable and look neat. This is clearly seen in the next photo, and the video will show the process of assembling the hood in the garage from plastic pipes. Despite the utilitarian simplicity, such a system for the garage will provide a normal microclimate for small and medium-sized rooms.
Important notice. In case of high humidity in the cellar, for example, due to the close occurrence of groundwater, the end of the exhaust pipe falls slightly below the ceiling. Underneath is a condensate collection tank that needs to be emptied periodically. It is convenient to use a wide cuvette stretched along one of the walls in the cellar to accumulate condensate.
Supply and exhaust ventilation
If the system, built on natural air circulation, does not provide the necessary microclimate in the cellar of the garage, you can easily and cheaply improve its performance. This is done using the following devices:
- a vane-type diffuser is mounted on the feed pipe, which constantly captures the wind flow and blows it into the basement space;
- An incandescent bulb is installed inside the exhaust duct. Its heat heats the air and makes it move up more intensively, increasing the volume of circulation;
- Good results are shown by installing the deflector on the chimney. It forms a low-pressure area, as a result of which the hood in the cellar works much more efficiently.
Despite the simplicity of such measures, they are quite effective. However, with a sufficiently large amount of air in the cellar, they may not be enough. Then it makes sense to install a fan in the exhaust pipe, which will forcibly form the outgoing air flow.
If the exhaust and supply pipes are made of sewer plastic, installing a fan is not difficult. It is only necessary to purchase the product of the right size and place it in the joint between the elements. The following photos and videos show how easy it is.
For rooms with high ceilings and with the existing “full-size” cellar, a forced draft, built on electric motors, is mounted. Practice shows that even compact uncontrolled fans mounted inside the exhaust pipes dramatically increase the overall efficiency of the system.
The device for forced circulation can be very simple and can be mounted without much difficulty. The installation result and installation process are not shown in the following photo and video.
However, when creating the supply and exhaust ventilation, it is necessary to adhere to several rules:
- the efficiency will be final and low enough if only forced removal of air in the cellar is created. Therefore, fans must also be mounted on the supply pipes;
- in the cold season, an uncontrolled supply and exhaust system can dramatically freeze the space in the cellar. Therefore, it is recommended to use the simplest electronic control elements based on temperature control.
For reliable operation of complex hoods in the cellar or basement of the garage, software systems are used. It can be either a turnkey solution or an individually designed one. Today, the market offers so-called monoblocks that immediately contain everything you need. However, the price of such a garage solution is prohibitive.
Conclusion
A quality hood mounted in the cellar or basement of the garage can be very simple, but it can work very efficiently. When developing a system, it is worth remembering that its main parts are the exhaust and supply pipes. Having created them from the necessary materials, you can go the way from simple to complex, achieving the necessary parameters of the supply and exhaust ventilation of the garage.
