Ventilation systems in most cases have a design designed for air exhaust or discharge. In one case, the channels remove the spent dirty masses, and in the second, they facilitate 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 that provide for more in-depth training of the injected masses. In particular, the supply chamber allows not only filtering the air, but also providing heating if necessary. Accordingly, the installation has a special design, as well as special installation requirements.
Supply chamber design
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 receiving department, a warming valve, etc. This infrastructure is designed to organize several stages of processing air masses in accordance with the tasks set. In addition, the supply and exhaust chambers may provide for the possibility of disassembly in case of movement. Transportation is subject to 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 galvanizing layer, which protects the chamber from the appearance of rust.
Section Organization Methods
To begin with, it should be noted that the sections themselves in the chamber can have different purposes. By the method of the device, connection configurations with the primary and backup fans are usually distinguished. Actually, in simple models, additional functional components are not used. Such a solution is common in installations that serve large enterprises, where there are large flows of air. In addition, the supply chamber is equipped with sections of a heater, which can also have different designs. In particular, sections with lateral channel placement, with a central bypass output and with a combined branch line are common. In addition, each section can have several heaters. The choice of this or that configuration of the arrangement and arrangement of sections is ultimately determined by the requirements for the capacity of the installation and the requests of personnel in terms of maintenance.
Preparation for installation
Preparatory measures consist of several stages, including the installation of the foundation and verification of components. The foundation is performed by the type of screed. Usually a 10-centimeter layer of concrete is formed on which a supply chamber is subsequently installed. Ventilation should be mounted only on a flat surface - the quality of the functional parts, including the air heater, will depend on this.
Usually, assembly is already done at the place of future operation. Component parts are unpacked and laid out by type immediately before installation. Next, you should sling sections for the eyes or holes that are provided specifically for this task. In order to prevent defects from being detected during the use of the structure, when it is no longer possible to fix them, the supply chamber must be checked for technological violations, size deviations of individual modules, etc.
Installation of a typical supply chamber
Work begins with the installation of the receiving section on an established foundation. During the installation, it is important to consider the nature of the junction of the camera to the side of the air intake module. Then you can proceed with the installation of the complex with insulated flaps. Depending on the design of the camera, before mounting this operation, it may be necessary to mount the adapter pipe. It must be adjusted and adjusted in advance based on the thickness of the wall. After that, the installation of the supply chambers goes to the stage of installation of sectional units. The first is usually attached to the air heater, and then the irrigation and connecting modules. Fixing to the camera is realized by means of complete bolts.
Camera automation
Providing cameras with automation systems provides many advantages. 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, it can be maintaining a predetermined temperature regime, monitoring the function of an electric motor, fixing power surges and protecting against overloads, turning off equipment during fire alarms, etc. Obviously, for the implementation of this functionality, the supply chamber must also include an appropriate control infrastructure. Typically, at large production facilities, this problem is solved by including a supply air chamber in the programmable controller system, which is also responsible for the operation of other engineering systems.
Conclusion
In most cases, supply air chambers are used as part of public utilities for 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 a compact compact supply camera with a minimum set of functions is required rather. These units are easier to manage, not to mention simplified preventative maintenance. In addition, it is advisable to initially complete household models with noise reduction systems, since the operation of the unit can be accompanied by strong vibrations.
