For the operation of such a ventilation system, air exchange depressurization is used. The suction of air from the room occurs due to a decrease in pressure inside the house in relation to street pressure. Fresh air enters the house with the help of built -in outlets and leaks.
Most often, a ventilation system with depressurization is used in countries that have a cold climate. In those countries where there is a hot and humid summer, depressurization will contribute to the penetration of humidity into the house, which will adversely affect the walls of the house, destroying them.
Such a system differs in its simplicity and small cost. The composition of the system with depressurization usually includes only a fan associated with the central point of the outputs of non -stable air out.
To ensure fresh air of all rooms at home, the fan is connected to the ventilation pipes, which are installed in several rooms at once, where constant purification of dirty air is required, like a bathroom, toilet, kitchen.
It is better to entrust the installation of such a system to specialists, it is even better when the manufacturer itself will install, ventilation and air conditioning in Kyiv is actively developing and prices are quite affordable.
To ensure a ventilation system with depressurization, mobile ventilation holes and passive are used. The first type of hole is built into the windows and walls, so they can be installed in about all rooms. The second type of holes, due to the difference in the pressure that appears due to the fan operation, are less effective.
Very often in bathrooms, local ventilation is used with depressurization, which is the most ordinary system based on depressurization. Such a ventilation system works on an ongoing basis.
Local ventilation helps to increase the qualities and efficiency of other systems, perfectly coping with the elimination of pollutant agents from the house, as well as excess moisture.
Local ventilation with depressurization is a depressurization itself and localized fans, which are needed for the exhaust of harmful substances.
Poor ventilation work with a depressurization system along with local fans used for air exhaust contribute to the penetration of various pollutant agents that can come with fresh air. It can be mold or radon, which is contained in semi -passage channels and cellars, and dust from attics. Very often fresh air spoils smoke gases from close bonfires or installations, for heating water, which carry out their work on fuel. Due to weak ventilation, smoke and gas from garages enters the house.
