Ventilation in the garage: which one to choose?
Some car owners believe that goodThe ventilation in the garage is not the first priority. This is a very profound error. After all, it is the ventilation system that determines not only the condition of the car, but also the health of its owner. Ventilation is designed to maintain the correct exchange of air in the garage, clean it of toxic impurities, unpleasant odors, regulate humidity.
The ventilation of the garage can be natural,mechanical or hybrid (combined). Natural - the cheapest, but not always reliable. For its device does not need expensive equipment or professionals: the system can be organized independently.
Mechanical - reliable, but expensive.
Therefore, the most popular for today is the combined ventilation in the garage.
For the device of combined ventilation to begin it is necessary with creation of system of ventilation natural.
The natural ventilation of the garage is arranged as follows: On the entrance gates or the adjacent wall there are louvered grilles for inflow and outflow of air. They are called differently: supply, exhaust or overflow lattices. Blinds, through which air enters the garage, should be larger in area (about three times) those through which air is drawn out.
When you equip the system, you can not do withoutdeflector - a special device that pumped air from the room to the street. It is recommended to install it in the place of the roof where the exhaust duct ends. Then, under the influence of the deflector inside the duct, a low pressure zone will form, which guarantees a minimum air flow. The use of any mechanical devices in natural ventilation is uneconomic, because they are heavily influenced by weather conditions, which often increase airflow.
In order for the ventilation in the garage to function properly, the deflector should be placed first, vertically, and, secondly, opposite the intake grilles, at the end wall opposite the gate.
Very often condensation forms in the garage. To reduce its number or completely eliminate formation, a deflector is installed heat insulation. In this case, it should be taken into account that only the external air duct, which is at least half a meter above the garage, will work normally. Usually, external ducts are made from tin or asbestos on their own.
Ventilation in the garage requires installation on aoverflow louvres of gates (special dampers), by means of which it is possible to increase or decrease air exchange. In summer, in a strong heat, these slats should be as open as possible, and in winter they are slightly opened so that the air can quietly enter the garage. The first one opens the intake grate, the second - the exhaust grate.
The natural ventilation in the garage largely depends on the weather, wind force, temperature on the street, so it is ineffective.
In order to improve air exchange, this system is supplemented by forced ventilation. Most often install an exhaust fan to get the simplest combined ventilation system.
If the garage is heated or there is moreone machine, it is advisable to install mechanical ventilation. Its main parts - the heater, fan, air filters. To save on heating, competent garage owners supplement the system with recuperators. These devices allow transferring the heat of the exhaust air to the one that enters the garage.
Despite its high cost, this forced (mechanical) ventilation pays off very quickly, allows you to save the car, and the owner of the garage is in comfortable and safe conditions.
