All living things on earth needs a good quality, unpolluted air, good air circulation is necessary for normal functioning of various production mechanisms. That's why it's important to equip manufacturing process related specifically designed (on the project and prior to installation) for a certain kind of working environment ventilation system. Before you design and install ventilation specialists are studying the existing objective conditions. Such as the prevailing weather in the area, especially the microclimate inside the premises, the internal structure of the premises, and sanitation regulations, hygiene, noise, and determine the optimal intensity of the air supply, etc. Certainly, most people have an idea of the fan. The thing is, now widespread, but it turns out, the ancient people have made simple steps to maintain the freshness of indoor air. For centuries until the 19th, the circulation of indoor air was carried out in a natural way.
The advent of the fans we are obliged to scientific thought, MV Lomonosov Moscow State University Gave new impetus to the use of ventilation heat during its operation, undertaken in the nineteenth century. Significant negative change was too great heat consumption and, consequently, cost. Indeed undeniable breakthrough was caused by type of ventilation, which are called centrifugal fans BP. 'Ancestor' of modern EC more than 170 years old, his birth year – 1832. Three years later he began to be used for ventilation in the Altai Mountains (it was mine Chagirskogo). The idea to use this fan belongs Sablukov AA He also decided that it would be nice to use it indoors, holds, in order to speed up the drying and the like. It should be noted that only the end of the nineteenth century, these fans have become common.
There are 3 basic types of fans used for forced air. This – the radial Fans BP (also called centrifugal), ducted axial fans and BO. Especially popular lately duct fans VC. They are made specifically to mount them in the air duct channels that sometimes claimed. Not small, the contribution of local scientists in developing this type of fan, but still we must admit that the main contribution made by foreign manufacturers. They have made every effort to ensure that the channel fan was the most functional, and has earned universal recognition of consumers around the world, and began to bring significant revenue producer. A variety of models duct fans, even very impressive. It is noteworthy that this type of device can be placed directly in the duct, and secured to the surface of the wall or ceiling. Do not forget that choosing the right duct fans VC is quite difficult, since must take into account the different requirements and factors (for example – power, dimensions …). The correct choice of ventilation system, equipment, competent calculation, design and installation will ensure proper ventilation in the room needed as a human activity, for their effective operation, animals, and for productive, work-friendly industrial equipment.
