Depending on conditions of ventilation system exploitation airways can be made of various materials. To transmit air of 80C and 60% humidity airways are made of:

thin sheet cold-rolled zinked steel with 0,5-1,0 mm thickness, State standard 14918-80 ( 200-420 g of zinc for 1 m2 of steel)
thin sheet hot-rolled steel with 0,5-1,0 mm thickness, State standard 16523-70, State standard 19903-74 (steel without cover)###

Air-conditioning systems and ventilation

2008-09-09T20:36:27Z

Correctly designed, professionally installed air-conditioning systems play major role in premises. Air making, favorable for people`s health is not only humanity feelings, but also accordance with requirements of technological process, equipment and construction preservation, materials, products, etc. Companies very often need ideal controllable climate.

Ventilation system types.

Ventilation can be blowing and exhaust. Principle of operation of blowing: inflow of fresh air into the, exhaust – selection of polluted air out of the room. Combined system is often used: blowing-exhaust, which allows achieving bigger effect when airing the room.

What`s the difference between air conditioning and ventilation?

Very often it`s important not only to arrange air exchange in the room, but also fix special parameters for the air. Irrespective of season, of heat and moisture parameters, air conditioning systems sustain necessary parameters of air exchange.

Air conditioning types.

In general, air conditioners are divided into 2 big groups: home and industrial. In its turn, industrial include – ported conditioner of high power, sensitive, central and systems of chiller-funk oil. These are systems with power more than 20 — 25 KW. They are used for servicing residential and administrative buildings, sales areas and sport centers, industrial and specialized rooms - area more than 300 square meters.

Ventilation and air conditioning assembling.

Ventilation layout.

This process is quite complicated and important, what means compulsory appeal to professionals.

Layout starts from defining necessary air amount, necessary for airing the room. After that – principal scheme of ventilation is made in accordance with all aerodynamic properties. At the end equipment is chosen and installed, controlling system is set up. Layout made by specialists of «VolgaVent» company, meet modern requirements and regulations.

Production of airways

2008-06-13T19:30:28Z

Airways are made out of galvanized steel in accordance with State Standard(24751-81)
Tightness of all details - class <П>( compact)
Juncture of airways – by nipples using silicon sealing material and fixing by фиксацией rivet and bolts. Rubber juncture can be used for tighter airways.
