The principle of operation of a duct fan is simple in its essence, but it is very complicated when examined in detail. For proper installation, it is very important to understand how this climate technology works. Why is it needed? The answer is simple: for air exchange in rooms when the operation of other similar equipment is not enough.
Simply put, duct fans, which can be bought at the link https://fortochka.com.ua/shop/ventilyatory /kanalnye-ventilyatory.html , are systems powered by electricity and built into the duct to interact with clean and stale air. This interaction allows for an exchange between them, so that old air is removed from the room, and clean air is supplied instead.
The supply or exhaust duct fan is powered by a terminal box located on the outside of its casing. From the box, the wires extend outward long enough to reach the wiring or, in some cases, the outlet. It is also possible to connect automation to the terminal box, which makes it possible to control the rotational speed of the fan blades. It is useful to have such a function to save electricity and increase the service life of climate control equipment.
Depending on how the duct fan should work, its blades can be turned both at a positive angle and at a negative angle. Accordingly, in one case, the equipment operates to extract air from the room, and in the other case, to supply it. A few words should be said about the duct fan housing.
It comes in two form factors: rectangular and round. Whatever its case, the main thing that manufacturers of duct fans should take care of is the aerodynamics created in the space free from the blades. The service life and efficiency of this technique depends on it.
There are a myriad of areas of application for this climatic equipment, since ventilation is used in almost any residential and non-residential premises. But if we talk about categories, then the following can be distinguished. This:
- multi-storey residential buildings;
- residential cottages;
- office space;
- production areas;
- supermarkets and other sales areas.
Depending on the type of premises, it is necessary to install duct fans in accordance with the rules and regulations for this case, otherwise you can not only disappoint the customer, but also endanger the life and health of people living in the building. It is important to understand that no deadlines can be higher than human lives, �
