How to solve the problem of fresh air in the house, because the main time we are in it? In this stat, I will talk about how to improve ventilation in the house.
Of course, first of all, good ventilation is necessary in places such as the kitchen, bathroom or bathroom. Here oxygen is consumed quite intensively, constant increased humidity and various strong smells.
The standard hood installed above the kitchen stove for removing air to the outside is an essential element of the ventilation system in the apartment. It is only necessary that it is not the only air removal channel.
And the hood over the stove, working as a filter, that is, performing air purification in the kitchen, is quite an impractical device, since the filter is quickly polluted and its effectiveness is approaching zero.
But the rest of the houses also need ventilation, since the apartment has a gradual accumulation of radon gas, and different products of human life (per day, one person, only carbon dioxide emits more than one kilogram). In addition, high humidity without a good system of flow of fresh air, contributes to the appearance of dampness and fungus in the rooms.
For example, take a regular room (bedroom) with a volume of about 50 m. cube. So that humidity in this room becomes 100%, in its air you need to dissolve in the form of steam up to 870 g of water. If initially in the air of the bedroom there were 217 grams of steam, then the relative humidity was 25%.
If there is no ventilation, and the windows and doors are closed, then from 2 people in 8 hours, about 500 g of water will evaporate into the air. And the humidity in the room will reach almost 100%. It is clear that with smaller volumes of the room, the situation will be even worse. Of course, the exchange of air through the gaps slightly improve the situation, but
It is quite obvious that good ventilation can not do here.
Many of those who changed the old windows to hermetic plastic are faced with the need for ventilation. This is evidenced by constant fogging, which indicates high humidity.
You can certainly say: “We will do without a ventilation system – we will ventilate through the windows!””. Yes, ventilation is effective, but is it convenient? After all, to replace air in the apartment, you need to arrange a draft. In addition, if in winter such ventilation is quite effective, then in the warm time – ineffective.
For the kitchen, bathroom and toilet, there is a local exit – local ventilation. It can be, air valves in the windows, a probe above the kitchen plate or ventilation holes in the walls on which a supply grille with a valve is installed. These are not very effective, although rather economical methods. In addition to the fact that the flow of air is small and poorly regulated, it enters the house of the same temperature as on the street.
There is a more effective method for any room – this is when fresh air outside, is supplied mechanically, and is excreted by natural. The easiest way to provide air supply is to install a monoblock supply installation.
Such an installation supplies outer air into the room, passing it through the filter and heating to the required temperature. Such air is supplied to the rooms, to the kitchen or to the bathrooms. Air supply to the rooms is possible because even when designing a house in them, exhaust ventilation channels were designed.
Monoblock, designed for a separate room, is installed from the inside, under the window, and supplies air through a laid ventilation duct with a diameter of up to 150 mm. Outside, on the hole of the canal, a ventilation grill is placed. Such a indoor monoblock can be easily and easy to install in a built house.
