Ventilation systems in most cases have a design designed for the removal or injection of air. In one case, the channels remove the spent dirty masses, and in the second, they contribute to the flow of clean flows from the outside. Supply systems rarely do without filtration barriers and installations that provide primary air purification, eliminating the same pollution. But there are also special versions of such equipment, which provide for a deeper preparation of the injected masses. In particular, the supply chamber allows not only to filter the air, but, if necessary, to provide its heating. Accordingly, the unit has a special design, as well as special installation requirements.

Design of supply chamber

The installation is formed by several functional parts and components that form the frame. Active working elements include: an irrigation chamber, a heater section, a reception area, an insulation valve, etc. This infrastructure is designed to organize several stages of air mass processing in accordance with the tasks set. In addition, supply and exhaust chambers may provide for the possibility of disassembly in case of movement. Transportationcarried out on the condition that individual sections are provided with special protection. As for the hull base, it is usually formed by metal panels. Depending on the modification, manufacturers use steel sheets with different treatments. Among the main conditions for the long-term operation of the ventilation duct, one can distinguish the presence of a galvanized layer, which protects the chamber from rust.

Ways to organize sections

To begin with, it should be noted that the sections themselves in the chamber can have different purposes. According to the method of the device, connection configurations with the main and with the backup fan are usually distinguished. Actually, in simple models, additional functional components are not used. This solution is common in installations that serve large enterprises, where large air flows pass. In addition, the supply chamber is equipped with heater sections, which can also have different designs. In particular, sections with a lateral placement of the channel, with a central bypass exit and with a combined branch line are common. In addition, each section can have several heaters. The choice of one or another configuration of the location and arrangement of sections is ultimately determined by both the requirements for the capacity of the installation and the requests of personnel in terms of maintenance.

Preparation for installation

Preparatory activities consist of several stages, including the installation of the foundation and the verification of components. The foundation is carried out according to the typescreeds. Usually a 10-cm layer of concrete is formed, on which the supply chamber is subsequently installed. Ventilation should be mounted only on a flat surface - this will determine the quality of the functional parts, including the heater installation.

Usually assembly is done already at the place of future operation. Component parts are unpacked and laid out by type immediately before installation. Next, you should perform the slinging of the sections for the eyes or holes that are provided specifically for this task. In order to avoid detecting defects during the use of the structure, when it is no longer possible to fix them, the supply chamber must be checked for technological violations, deviations in the dimensions of individual modules, etc.

Installation of a typical supply chamber

Work begins with the installation of the receiving section on the arranged foundation. During installation, it is important to take into account the nature of the adjoining chamber to the side of the air intake module. Next, you can proceed to the installation of a complex with insulated dampers. Depending on the design of the chamber, it may be necessary to fasten the transition pipe before starting this operation. It must be pre-adjusted and adjusted to the thickness of the wall. After that, the installation of supply chambers proceeds to the stage of installation of sectional blocks. The heater is usually attached first, and then the irrigation and connecting modules. Fixation to the camera is realized by means of complete bolts.

Camera automation

Providing cameras with automation systems brings many benefits. The level of such control may be different, but even inexpensive block models allow the possibility of integrating systems with a modern set of automation options. In particular, this can be maintaining a given temperature regime, controlling the function of an electric motor, fixing power surges and overload protection, shutting down equipment in case of fire safety signals, etc. Obviously, to implement this functionality, the supply chamber must also provide for an appropriate control infrastructure. Usually, at large production facilities, this problem is solved by including the supply chamber in the system of a programmable controller, which is also responsible for the operation of other engineering systems.

Conclusion

In most cases, supply chambers are used as part of the utility supply of industrial facilities. But even in domestic conditions, such a ventilation module may well come in handy. Some modifications are quite suitable for operation in technical or utility rooms, realizing air renewal in accordance with the owner's requests. Another thing is that in this case you will need a more compact type supply chamber with a minimum set of functions. These units are easier to manage, not to mention easier preventive maintenance. In addition, it is advisable to initially equip household models with noise reduction systems, since workblock may be accompanied by strong vibrations.
