Features of garage air exchange
Good ventilation in the garage helps to avoid problems with the car. For example, in cold and rainy weather, when entering the garage, the car brings with it a huge amount of moisture. Due to the small space, the room quickly fills with moisture. If the volume of humid air does not change at least 6 times per hour (ideally - all 10), then the car will soon rust.

The winter temperature for a car should be +5 degrees in a heated garage. This feature should be taken into account when installing ventilation, although SNiPs allow not to turn on honduras mobile database devices. The car owner chooses the standards for his garage himself.

There is a standard for air exchange in a garage - 150 sq. m/h for each parking space. This is not a difficult task and is based on the following points:

the diameter of the air ducts is determined;
the second one is placed on the hood (you can see tips on installing a hood with your own hands with or without a vent).
There is a random renewal of air masses. This is an ideal example for a normal climate. In sharply continental conditions, it is necessary to carefully approach the issue of installing ventilation.

Natural
This type of ventilation provides a natural air flow. For these purposes, two ventilation holes are made - an exhaust and an inlet. To speed it up, a deflector is installed. It is placed in the exhaust hole itself. A low-pressure section is organized near this section. This must be done to quickly remove air.

Advice Air moves due to the difference in density of heated and cooled air due to the effect of wind currents and due to the movement of air masses when they interact at high and low pressure. Air circulation becomes weaker in summer, and drafts are possible due to pressure changes. With natural ventilation, constant monitoring of the condition of the ventilation openings is required. They must be cleaned regularly.
