About some existing myths and misconceptions about ventilation systems

One of the most common misconceptions that one has to face is the misconception that it is enough just to install the exhaust part of the ventilation system, and a comfortable microclimate is guaranteed. But in practice, everything is far from what it might seem. For example, a good proof of this is the situation with the room in which plastic windows are installed. There is practically no ventilation in such a room, especially if the windows in the room are closed. At the same time, even open exhaust vents in the bathroom or in the kitchen will not save the situation. You need to understand that the air must “come” from somewhere in order to “come out” later.

The next myth that I would like to debunk is the judgment that the ventilation system is a rather bulky contraption. Many still believe that the ventilation system consists of large fans, ducts of the same impressive size. And all this «magnificence» still needs to be hidden behind a suspended ceiling. And the price of such a system is very high, at least no less than twelve thousand dollars, and a very good and high-quality system costs about twenty-eight thousand dollars.
In fact, in reality, a sufficient air exchange rate in practice turns out to be much less than that calculated in accordance with the “formulas”.

It is not always clear why many are guided by the standard of 500 m3 of air per thousand m2 S per hour. In fact, the air flow rate for a cottage, which is characterized by an average area (about 400 m2), ranges from fifty to two hundred m3 / h. In addition, it should be taken into account that the number of people living in a cottage, a house also affects the value of this indicator. For example, in winter, it is very important to carry out ventilation in a dosed manner. If this process is carried out continuously, the air will be very dry.
Myth No. 3 is considered to be the belief that the ventilation and air conditioning system must be equipped with «smart controllers», with the latest technology. If this is not the case, then such a system is already outdated and far from perfect.

Here you must understand that in our time, innovations appear very quickly and sometimes you just can’t keep up with them. Of course, you always want to keep up with the times, but this entails significant costs and investments. But if you are ready and want your air conditioning and ventilation system to be state-of-the-art, be prepared to spend an additional ten to twenty thousand dollars.
