Installation of ventilation systems.

Installation of ventilation systems is the next stage after the design and costing. Installation of ventilation systems includes a consistent installation of all elements of ventilation systems - installation of equipment and components and installation of air ducts. This work requires certain skills and qualifications of installers, elementary knowledge in the field of ventilation. After all, for example, having no idea what an inflow or exhaust ventilation is, without knowing what a filter or a check valve serves, and how they work and are installed, and even knowing all this, but not being able to read the drawings, is unlikely to succeed correctly to assemble the simplest ventsystem.

Preparation for installation

Installation of ventilation systems, as well as any other production has a certain sequence, technology, involves the use of special adapters and tools.
Installation of ventilation systems of any complexity is carried out in accordance with the project drawings, - ventilation plans and axonometric schemes, where the air ducts are indicated, their intersections, the location of equipment and components, the height at which installation of air ducts and equipment is carried out. If there is no design documentation for any reason, the designer of the installation organization is to execute the relevant executive circuit for installation. In advance, the marking of the proposed route of air ducts, punching holes in the walls, specifying the locations of equipment and components is carried out. It is necessary to pay attention to their correct installation, - the direction of air flow, the corresponding location of the return valves, throttle valves, etc.
Installation of air ducts, both rectangular and round flanged, is carried out after filling on the flanges on their ends, to connect air ducts to each other. Until recently, steel rectangular corners were used as flanges of rectangular air ducts, with subsequent painting and installation of rubber seals between adjacent flanges. This made installation of ventilation systems, the actual installation of air ducts rather laborious, in addition, rubber seals eventually crumbled, requiring additional periodic maintenance ventkanaliv. This method is not used in recent years. For circular air ducts as a flange, rolling is still applied to the diameter corresponding to a steel angle made at the junction.

For the manufacture of flanges of rectangular air ducts, special shintoffs are used, which are stuffed at the end and interconnected by angles. In the corners there are openings through which with the help of bolts, nuts and washers and interconnect air ducts. Shinotraiki and angles are two standard sizes - for air ducts with a side less than 800 mm, flanges are used with a width of 20 mm, for larger sizes - 30 mm wide and their corresponding angles. For sealing joints, special self-adhesive sealants are used.
For circular spiral airborne ducts, which have recently been widely used, special nipples and couplings are used as connecting parts.
To mount ducts and components to the ceiling or wall there is a large number of perforated profiles of various sizes, special pendants, brackets and clamps. Materials for insulation of air ducts are also represented by a wide range of self-adhesive sheet insulators of different thicknesses. All this makes installation of air ducts, all installation of ventilation systems is less labor-intensive and quite simple.

It should be remembered that in order to provide in a room of any type (whether it is a large enterprise, or a small cafe) a normal microclimate, calculation (designing) and installation of ventilation systems, it is always need to be entrusted to specialists.
