Window ventilators

The climate at home should be conducive to rest and family responsibilities. For proper air flow, windows should be equipped with window ventilators that ensure proper ventilation of rooms. Thanks to them, the air is exchanged from the outside and between rooms. Why is the installation of diffusers so important and which model to choose?

Why use window ventilators?

The list of advantages of using window ventilators is very extensive. The most important is clean and fresh air, without mould, fungi, bacteria and viruses. Properly ventilated rooms are free from moisture or cold. In addition, using windows with ventilators we reduce heat losses, and thus save on heating. The air exchange through the ventilator in the window is permanent and automatic, so it is always refreshed. It is very important especially during trips, when we usually close the windows for safety reasons. When you return home, you will have a pleasant atmosphere instead of dust and suffocation.

Aeration methods through windows

Ventilation at home can be done in several ways. One of them is window infiltration, which can take place without the installation of window ventilators through closed windows, when the air infiltration coefficient "a" is 05-1,0 m3 /(m * h * daPa2/3). Another way is to use the so-called microventilation, i.e. unsealing the window sash using micro-tilt. However, the window must be constantly monitored to regulate the air supply to the rooms. We can also remove a fragment of the gasket to allow air to pass through the opening or install a ventilation flap. Window ventilators are also an effective and regular way of aerating, as they automatically and continuously supply fresh air to the rooms.

Window ventilator types

Due to the way of operation we distinguish hygroregulated ventilators, i.e. automatic, pressure (self-regulating) and manually controlled. In the first model, the air flow is dependent on the water vapour in the room, resulting from activities such as cooking, drying, ploughing, etc. The air flow is dependent on the water vapour in the room. In hygrosterone ventilators, the process is controlled by polyamide tape which, under the influence of humidity, regulates the degree of air flowing in. The pressure differential pressure in the room is dependent on the difference in pressure between the outside and inside the room, and the user can also close the blades to limit the airflow. In the case of manually operated aereco window ventilators, the amount of air supplied depends on the position of the shutter. It is the user who adjusts the degree of opening of the air vents by manually changing their position. Most often a hygro-controlled air inlet aereco is used where we can not use previous models.
