Duct fans

If more recently the ventilation system in the room was perceived as an excess, now it became absolutely clear, without ventilation it is not realistic to achieve a microclimate in the room. Well, it should also be noted that ventilation at some firms is most needed, as it provides the optimal conditions necessary to obtain the level of the production process. I repeatedly solved the issue of effective ventilation, and once I got the Innova ventilation system. I note that the plant Innnovent produces ventilation equipment for a long time, and for the years of its production activity has the prospect of gaining prestige in our or foreign markets. However, I would like to talk not about the company, but specifically about ventilation equipment. Let's start with roof fans. Roof fans are installed on the roof of buildings. They are adapted to remove non-explosive mixtures from air in public or industrial buildings. Such systems operate under conditions of temperature not exceeding +50 Celsius. It is difficult to imagine ventilation without lattices. Of special interest are ventilation grilles, the mechanism of which helps to fix the angle of the slope of the blind, reducing or increasing the amount of air that is passed through. Very comfortable scheme, especially in those industries where it is necessary to regulate the degree of ventilation, depending on a number of factors, for example, air humidity.
Referring to the fans, you need to remember such a subspecies as channel fans. This kind of systems is necessary for direct mounting inside the channel. The fan in this situation is selected strictly by the size of the channel. It is very important that the parameters coincide, otherwise there is the possibility of encountering such annoying phenomena as noise or vibration. Channel fans can have different shapes, in most cases, round or rectangular. The construction of such a fan is not very complicated. In the form of design differences, you can see direct transmission, thermal contacts, the presence of a motor with an external rotor. I would recommend choosing modifications with bearings that do not require maintenance. This will significantly ease the maintenance and extend the running time. Another type is radial fans. Radial fans are also called centrifugal, because their method of operation is based entirely on the combination of a fan design with centrifugal force. In constructions of this kind, a different number of blades can be used, which are folded in different directions.
Along with ventilation systems, air conditioners are important. How much do we know about air conditioners? In the case if it is a split system, the main points are as follows: distribution communications, central air-conditioning, local air-conditioning units. I would like to emphasize that in the installation of ventilation systems and in the installation of an air-conditioning system, the correct calculation is essential, which makes it possible to choose the optimal criteria. If the calculation is not correct, the system may not be able to reach the capacity to maintain optimal ventilation parameters, or, conversely, excess power leads to an inefficient use of the power supply.
