How to make ventilation in the garage?

Every car owner wants to keep his vehicle in excellent condition. For this, it is necessary that the machine is in optimal conditions.

Some garage owners are skeptical about the presence of a ventilation system in it. They do not pay attention to the fact that the slow exchange of air leads to damage to the car. Due to poor ventilation, the vehicle quickly rusts and collapses. Since not all garages are equipped with good ventilation, in this article we will look at how to do it yourself.

If the task is to independently build a ventilation system in the garage, then any car owner can cope with it, if he, of course, has an idea of ​​how this is done. There are several types of creating optimal air exchange:

• enforcement system;
• combined;
• natural.

The latter option is characterized by minimal costs. Forced exhaust will be optimal in those rooms that are heated. This is necessary because the difference between the temperatures inside and outside the garage will be big enough. This leads to the fact that the constructed ventilation system in a given period of time should be as efficient as possible. To create the correct ventilation, it is necessary to develop a detailed scheme of its construction.

Many car owners do not understand why. In fact, ventilation affects many points and can solve many problems. The system in question is necessary for several reasons:

• To protect the vehicle. This is what any car owner should worry about. If the machine is located in a room with high humidity, the metal elements will corrode. First of all, all the elements that open will suffer. That is, the doors, trunk and hood will rust.In addition, the presence of moisture will negatively affect the functioning of the mechanics and electronics in the vehicle.
• To protect the garage itself. Those materials that were used for the construction of the garage, also do not accept dampness. The metal pillars of the building will collapse over time, and the wooden elements will start to rot. Concrete and other binder coatings will be eaten by mold.
• To protect people. If there is poor ventilation in the garage, the fuels and lubricants fumes have no place to go, so they will gradually accumulate in the garage room. Visiting this place, the person will be exposed to toxic effects. In some cases, headaches or even poisoning may occur.

• The importance of ventilation in an existing inspection pit / basement cannot be ignored. It is required there to remove odors and moisture. This basement should be equipped with its own individual ventilation system.
• Maintain optimum moisture. It should be borne in mind that in the winter season, snow and ice get into the garage together with the car.The room is warmer than outside, so they melt and turn into water vapor. As a result, the humidity in the room increases significantly, which is bad for the car.
• If you traveled by car in the rain or under the snow, then the body needs to be dried. You can perform this procedure through ventilation.

The ventilation system is able to remove condensate from the walls and ceiling, and can also dry the inspection pit.

In order to organize the proper operation of the air exchange system, the scheme should take into account the volume of air changes and seasonal temperature differences. The ventilation system depends on the following criteria:

• The difference between the temperature inside the garage and outside. The temperature concentrated in the garage should be slightly higher. In this case, the air from the street will be able to penetrate the garage through the constructed air duct in order to replace the denser air concentrated inside.
• The pressure difference in the vertical position of the inflow and pressure in the exhaust. Delta must be more than 3 m.
• The pressure of the moving air.On the more upwind side of the structure, an increased pressure must be established, and on the leeward side, a reduced pressure must be established. The air intake duct should be installed on the side where the wind direction prevails.

Before proceeding with the installation of ventilation in the garage, a calculation is required to determine the optimal diameter of the holes. You can perform this calculation in the two most popular ways:

• In the first method, it is necessary to use the ratio, where 15 millimeters of the diameter of the pipe per one square meter of space.
• The second method provides that when summing up the area of ​​all holes, they make up 0.3% of the total area of ​​the room. This formula is usually used when a single-channel system of a mechanical type is built.

In Russia, the norms stipulate that in one hour at least 180 m3 of fresh air should be delivered to the room. Abroad, this figure is 2 times higher. It is necessary that the ventilation installed in your garage satisfies these requirements, and for this it is necessary that the pipes have sufficient diameter.

It is necessary to develop the design of the ventilation system at the design stage, since the required openings need to be made in the walls and plinth when establishing the supporting elements. It is important that the number of floors, the number of vehicles to be placed, the stoves, the vacuum cleaner, the height and area of ​​one or several rooms be taken into account. At the considered stage, the owner of the facility should make a choice regarding the arrangement of the ventilation system, which could cope with its main task.

Today, the following types are known:

• Natural, which is based on the fact that the movement of air masses should be carried out without coercion on the rules of aerodynamics.
• Combined, where at the same time there is a principle of operation of the natural ventilation system and mechanical devices for the implementation of the stimulation of air movement.
• Mechanical ventilation, where there are various installations, creating an influx and outflow of air mass.

Different types of pipes can be used in the work, the diameter of which must be calculated based on the volume concentrated in the room, air, or based on the area of ​​the room. Previously, the two most popular methods for calculating the diameter of pipes that will be used to create channels were presented. It was noted that the optimal ratio is 15 mm in diameter per pipe per square meter.

If you use this method, then with a garage of 10 square meters you will need to use a pipe that has a diameter of 150 millimeters. Self-made ventilation system is often mounted by welding.

The previously mentioned second method is also effective, but it is used less frequently. Both of these calculation methods will allow you to determine the optimal diameter of the pipe to create a ventilation system and its painting. Choose between them based on personal preference.Next, we consider ways to install a ventilation system, depending on its type.

Before we get to work, it is necessary to calculate the diameter of the hole in the channel, as mentioned earlier, but in this case we will use a different method. In this situation, one square meter of room space accounts for one and a half centimeters of air channel section. Consider a good example where we use a garage with an area of ​​20 square meters. This value must be multiplied by 1.5 centimeters, where we will get a value of 30 cm. This is exactly what the channel opening section should be.

Then it is necessary to make special holes in the walls, taking into account that the pipes can easily enter them. Thus, the installation of a natural ventilation system is gradually being carried out. To create holes using a perforator, through which holes are punched in the ceiling. The indent should be no more than 20 cm. If the walls are made of foam blocks, then in the process of this work you will not have any difficulties.

Plastic or other pipes should be inserted into the hole.If iron is used to create ventilation, then holes are simply drilled in this case.

To create an influx of air masses, holes are made in the walls of the room. Their diameter must be optimal in order to install in the opening of the pipe. This will be our supply system through which fresh air will enter the room. In the same way, then the exhaust duct system should be performed. It will be necessary to punch a hole in the opposite wall, but it should be located as close as possible to the roof.

To do this, use the same tools. Pipes must be brought to the roof. As a result, you are settling in a natural ventilation system in the garage.

Please note that the higher the exhaust system is located, the better, but it’s best to stick with the best options. It is believed that the outlet, which is erected above the roof, should have a length of half a meter. Only in this case, the exhaust system will be considered correct. The formed gaps between the pipes and the chamber must be sealed with a sealant.

The advantage of the mechanical type of the ventilation system is independence from natural factors. Despite such a great advantage, the design has certain disadvantages, among which the following are present:

• system dependent on power supply;
• the acquisition of devices is a very expensive business.

In this situation, the inflow and outflow of air volume is carried out by means of specially installed fans. Mechanical ventilation systems that are used in garages can also be classified into certain types. Consider them in more detail:

• Modular systemswhere to create a supply and exhaust complex, several independent blocks are used, thanks to which fresh air is supplied and the polluted atmosphere is removed. Such modules are characterized by independence, and for their joint operation, control sensors are required.

• Monoblock systemwhere each unit acts as a complete mechanical ventilation device. In this situation, it carries out the inflow and exhaust simultaneously.The disadvantage of this system is that it consumes a sufficiently large amount of electricity. The most economical option are the models that are equipped with recovery plates. They will reduce the cost of electricity for the implementation of the heating air supply.

It should be noted that the second variant of the organization of mechanical ventilation is characterized by a simpler installation process. Here you need to prepare only one hole in the wall of the room. However, the performance is higher with the first option, where several modules are used to implement the process. In this situation, the fresh air entering the garage from the outside passes through a filtration stage, and in the winter period it also heats up.

The air is supplied through the channels through the holes that were made in the floor or in the walls in a place as close as possible to the floor. These holes are also present in the viewing pit. The exhaust air is carried out through the exhaust pipe, which is installed quite powerful fan.

When we deal with large garages,which are focused on storing several cars, it is best to do the exhaust through ducts and when using sewer pipes and duct ventilation. Heat fan should provide reliable ventilation.

In the presence of natural ventilation, it can be supplemented by using the forced method of organizing this system. With this supplement, you can increase the efficiency of the existing hood, so that it will function regardless of weather conditions. Additional equipment consists exclusively in the installation of the fan.

We recommend to stop the choice on fan heaters which will turn on depending on the external atmosphere. This is the best option for creating exhaust ventilation in the garage.

It should be noted that in this case, forced ventilation is practically no different from natural, but in this situation it is equipped with a fan, which will be periodically turned on, ensuring air flow. This is a simple device that works quite economically.The only thing that is needed is the correct location in the system. As a rule, the installation is carried out in the insulated area of ​​the air collector. It should be noted that The air intake system rarely fails.

You can install a thermal fan:

• straight into the wall;
• by another different method.

When the fan is in idle mode, it will rotate with the appropriate wind direction, moving the air in the room. It is an economical, but very efficient ventilation system that will be included only in the absence of wind. In the presence of wind, it will remain in excellent condition, but the intake system will function naturally.

In this situation, it is necessary to know the wind rose, for which a self-made or acquired weather-vane can be used. This device will allow you to know the wind direction.

Despite the large number of advantages of the combined system, many garage owners identified a number of disadvantages:

• it is difficult for them to turn the thermal fan on and off;
• the air that enters the room does not pass through the purification process;
• It is important to warm the system.

Whatever your garage, there must necessarily be a ventilation system, since it plays a big role in creating a favorable indoor climate. This directly affects the safety of your car, so it is important to consider this point. Remember that if the effective ventilation system is not concentrated in the garage, then over time you will begin to notice the presence of condensate, which will negatively affect the condition of your car.

Pay attention to the following points:

• To create a ventilation system in the garage with your own hands, you do not need special skills, however, having done this work, you will be able to organize a favorable atmosphere indoors.You not only save the car from rust and failure, but also prevent the accumulation of toxic substances in the garage. It is important to bear in mind that any such structure must have good ventilation.
• Make sure that in the winter time the temperature in the garage does not fall below +5 degrees Celsius.

• Be sure to take care of the organization of ventilation, which will favorably affect the microclimate of the room as a whole.
• When designing a future ventilation system, it is extremely important to consider the volume of the room.

• The choice of one or another type of ventilation system may be affected by the amount of air replaced. It is necessary to pay attention to what you usually do in the garage. If this room is necessary for you to fulfill orders, for example, as a paint shop, then natural ventilation in this case will not be enough, so you will have to opt for a different type of ventilation system.

We have already determined that inadequate ventilation is a danger to your car, to the garage and to human health. That is why it is important that it function properly. In order to achieve high efficiency, it is necessary to pay attention to the following important points:

• In the hood should be concentrated good traction, which is why it is usually placed at the highest point of the garage room.
• It is necessary that the pipe had a sufficiently large height.
• The outlet pipe must be protected from moisture. To do this, create a special fungus made of metal or other durable material that prevents the ingress of rain and other precipitates inside.
• Be sure to pay attention to the prevailing air flow, since the hood must be directed towards the wind.

As noted earlier, in the presence of a viewing pit, proper ventilation must also be organized in it. That is why it is important to pay attention to this type of work. Ventilation in the inspection pit can be performed according to the following algorithm:

• the repair pit needs to be opened at the edges of the inlet pipe,it is necessary to leave a gap of 15 centimeters wide;
• between the boards closing the cellar, it is also necessary to leave gaps under 10 centimeters;
• you must leave a small gap opposite the hood;
• it is necessary that the opening for the inflow was 2 times larger than for the exhaust.

Be careful! In no case should the car be placed on the zone in which the outflow from the inspection pit is concentrated. In this area is the most aggressive and humid environment, which will lead to the fact that the bottom of the machine will just rot. Any car owner should worry about his vehicle, so be sure to take into account such nuances.

If you know the best ways to organize the best conditions for storing a car, you will be able to significantly extend its operational life.

It is extremely important to choose the best option to create a good air exchange. Many garage owners prefer the combined method of organizing ventilation, noting its reliability, efficiency and versatility.The combined system allows you to get a decent result cheap and convenient, regardless of the season and weather conditions, while this system does not need a large amount of electricity.
