Ventilation is an important system in the garage. The integrity of the vehicle and the microclimate as a whole largely depend on its operation and functionality.
Proper exhaust in the garage is necessary to supply fresh air, which is so necessary for both the owner and his car. This type of communication is also responsible for the removal of volatile toxic substances and excess moisture.
Why is the hood in the garage?
Many garage owners are sure that non-residential premises do not need ventilation. The characteristic consequences caused by the absence of this system will help to refute this erroneous opinion:
- Dampness that appears in the garage has a destructive effect on the metal parts of the body, electrics, and electronic devices of the car. In addition to causing damage to cars, excess moisture accelerates the process of spoilage and decay of food stocks, causes fungi to appear on walls, wooden supports and other structural elements.elements of the room, which are made of wood and metal.
- The formation of a toxic environment has a negative effect on the he alth of the owner. If the hood is not made in the garage, an unfavorable atmosphere will form, causing a painful condition, headaches, and poisoning. Even if the owner of the garage does not feel the fumes from the incomplete combustion of gasoline, gas, diesel at first, later the accumulated toxins will definitely make themselves felt.
Establishment of a simple or complex ventilation system avoids many negative consequences. Moreover, outbuildings, according to the requirements declared in SNiP on February 21, 1999, must be equipped with this communication system on a par with housing.
How to make a hood in the garage?
A properly executed ventilation system is the key to a long car life.
If the hood in the garage is arranged correctly, in accordance with all the norms and rules of SNiP, then 180 liters or more of fresh air will enter the room daily.
In order to make ventilation in the garage, you should:
- know the number of cars that will regularly be in this room;
- make a calculation of the overall dimensions of the garage;
- determine the most comfortable location of the ventilation system;
- choose the right material for arranging the hood;
- install, if the plan requires additional equipment.
The hood in the garage is equipped in both two-story and standard one-story buildings. Ventilation must also be arranged in the cellar of the garage, because there is not enough air circulation in the isolated room of the basement to eliminate odor and dampness.
Types of ventilation
There are several ways to provide a car with a "breath of fresh air":
- A natural ventilation system based on the principle of generating air flow without forcing through the temperature difference between indoor and outdoor.
- Forced (combined) garage ventilation scheme, operating on the principle of forced exhaust from the exhaust air from the room and its natural inflow from the street.
- Mechanical ventilation, in which special devices (module, monoblock) are responsible for air exchange in the garage, which draw in fresh air and forcibly throw polluted air out.
- Exhaust ventilation, which uses a hood for ventilation. The disadvantage of such a system is that there is no air intake, because the air moves only in one direction.
- Inlet and exhaust ventilation.
How to make a hood in the garage? It all depends, as a rule, on the financial capabilities of the owner. An ideal mechanical system in all respects will cost the car owner $ 1,200 or even more. Yes, and the installation of expensive equipment will be carried outspecialist. If you make a hood for the garage with your own hands, then you should choose a natural or forced ventilation system. All types of ventilation systems are equipped with one or two channels.
Methods of ventilation in the garage
Not only the garage itself should be ventilated, but also the additional premises adjacent to it:
- Ventilation of the cellar in the garage should be done in an exhaust way so that the products stored in it do not deteriorate. How to make a hood in the cellar of the garage is described below.
- In the underground garage, ventilation should be carried out in a combined or mechanical way. Otherwise, the whole room may become covered with fungus and mold.
- In the vegetable pit of the garage, it is best to equip the combined system.
- The hood in the paint garage should be mechanical with many additional devices. Thanks to the continuous flow of fresh air, the paint will dry much faster. In addition, a well-made paint garage hood improves the quality of the paint job, reduces the cost of filter replacement, saves electricity, and also increases the forced drying speed.
- In the inspection hole of the garage, the ventilation is arranged in a natural way. Its action is due to the through flow of air.
- In a metal garage, the hood is equipped even during its construction. It is important that the ventilated hole has such a volume that the cold air does not allow the room to heat up.
- In a brick garage, a combined hood will be ide altype.
Metal and asbestos pipes are used to form a hole for the ventilation system. The diameter is selected according to the volume of air masses to be replaced.
Natural ventilation
This is the most affordable and inexpensive way to organize air exchange in the garage. Already at the construction stage of the building box, two holes must be provided in the walls for such a ventilation scheme:
- Fresh air inlet located near the floor (at least 10 cm from it). The outlet pipe passing through it is raised even higher above the ground (by about 30 cm). A mesh and a conical roof are attached to the end.
- Exhaust opening located near the ceiling (10 cm lower) to remove polluted air. The outlet pipe is raised 50 cm above the roof and is also protected from precipitation and insects with a net and a cap.
Disadvantages of natural ventilation
This system has a number of significant drawbacks:
- The effect of natural ventilation in the summer is practically reduced to zero. This is because the temperature is higher outside the garage.
- Differences in pressure inside the building will create a draft, which is undesirable for people who devote a lot of time to caring for their car.
- Due to the small size of the garage, temperature and pressure differences are not always sufficient for good circulation.
- It is difficult to predict the direction of the wind,therefore, air flow is not always supplied to the inlet.
Given the above disadvantages, people who do not want to depend on the gifts of nature, it is better to invest more of their money and make more expensive, but constantly functioning ventilation in the garage.
Combined ventilation
In its structure, this system is similar to natural exhaust. There are 2 openings in the garage: for the inflow of fresh air (near the floor) and for the exhaust of exhaust air (near the ceiling). But the difference is that there is no longer a dependence on the location of the holes. They can be located on the same wall and even on the same level, but they must not be placed against each other, otherwise the air circuit will close and air will not enter the room.
The difference of such a system is in the installation of electric fans in the output channels. Air exchange takes place according to the principle of pressurization: already exhausted air is forcibly removed from the garage, and fresh air enters the vacated space.
The combined ventilation system can serve all year round, and the exhaust fan is inexpensive and consumes little energy (100 W).
Forced exhaust ventilation in garages and cellars
In terms of price / quality ratio, this is the best option. This is the only way to createeffective ventilation of the basement in the garage and good air circulation in the inspection hole. Also, this is the only option for underground garages.
Conclusion
A hood device in the garage is a mandatory requirement that should not be neglected. You can equip budgetary natural ventilation or, if possible, install an expensive but effective mechanical system. Garage owners can also choose a combination method, which is a cross between a natural type of fixture and a mechanical installation. What the owner of a garage and a car chooses depends on his financial capabilities and requirements.
