Usually, "European-style renovation" begins with the installation of double-glazed windows and careful closure of all existing ventilation openings in the room. It is interesting, but few people know that by breaking the ventilation system in a house or apartment, you can permanently lose clean air.
choose supply and exhaust fan for homeExperts in this field do things differently. Even if the ventilation system does not perform its functions, it is not closed or broken. Why do this, because the situation can be saved by supply and exhaust fansthat can significantly improve the efficiency of the old system. Almost all residential or office buildings have a natural airflow ventilation system. When it is not cleaned for a long time, the debris accumulated in the air ducts becomes an obstacle to the normal circulation of air flows, and the system ceases to function. If the stagnant air is driven with a fan, even a small, free clearance in the duct will be enough for it.
To understand how heavily clogged the ventilation system in your home is, and which fan is better to buy, it is enough to bring a candle to the grates in the toilet, in the kitchen or in the bathroom. If the fire leans towards the ventilation hole, then there is a draft, and a simple fan can be installed. If the candle does not react to the proximity of the ventilation grill, it means that you need a "centrifugal" fan capable of creating a high pressure. In every apartment, at least in three places, it will not be superfluous to have a fan. This is a toilet, a bathroom and, of course, a kitchen.
Ventilation in the toilet
If the ventilation system somehow works, a simple exhaust fan will be enough for the toilet. It is attached directly to where the air grill used to be. In order for it not to emit a constant buzz, but to turn on only when necessary, it is connected to a switch. Some fans are turned on with a cord, but it is even better if this device is equipped with a timer. Then it will start working a minute after you leave the toilet. After working for the required time (usually 10 minutes is enough), the fan will turn off by itself until the next time. If you are a resident of our capital, then you can buy a duct fan in Moscow from Eco Climate.
Ventilation in the bathroom
A fan in a splash-proof housing should be installed in this room: neither a short circuit will occur, and water will not enter the duct. If financial means permitting, install a fan with a humidity controller. As soon as it exceeds its norm, the fan will remove the oversaturated air. This will make it easier to breathe, and the mirror will not fog up, and even the laundry will begin to dry faster.
Ventilation for the kitchen
In the kitchen, the need for fresh air is greater, and therefore a more powerful fan will not be superfluous than in the toilet or bathroom. Its performance can be selected by multiplying the footage of the kitchen by 10, and then subtracting the volume that the kitchen furniture occupies. In other words, for a kitchen of 6 sq. m. a fan supplying 120-160 cubic meters is required. m. per hour, and for a kitchen of 10 sq. m. - 220-300 cubic meters. in hour. At the same time, unlike a bathroom and a restroom, in the kitchen it is possible to equip not only an exhaust hood, but also an inflow of clean air from the street, for which fans are used, which are inserted directly into the window or window.
