Radial Fans type WRW
Adjustable radial fans low pressure type WRW production "Corf"which are used in ventilation and air conditioning systems provide air flow to 7300m 3 / h. Fans are designed to move air and other non-excessive gas mixtures. Fans are used to directly install into a rectangular channel of air conditioning systems and ventilation of industrial and public buildings. The permissible temperature of the moved air from -30 ° C to + 40 ° C. The fan is made of galvanized steel sheet 08pc grade as standard.
Working wheels Ziehl-Abegg. Qualitative, well balanced, therefore, noise characteristics are not worse, but on some sizes and better than imported analogs. The tests were carried out in GosNInzagi both on aerodynamics and acoustics. Official conclusions and test reports are obtained. The quality of the spiral of the fan is one of the main parts, on which the aerodynamic characteristics of the fan depends, obtained by a special method developed by Korf specialists, which is a new technology.
WRW fans are manufactured in eight sizes. In each sampler, there are several models of fans depending on the type of fan used. The production association "Corf" carries out an integrated approach to the creation of a microclimate in the building using high-quality equipment: fans, water heaters (two- and three-row), electrical heaters, noiseless, filters (pocket, pocket shortened, cassette), control dampers, control blocks, Industrial air curtains, sections of bactericidal air treatment, inlets, central air conditioners.
Bactericidal air treatment sections
Bactericidal air treatment sections SBOW Designed to disinfect air in medical, sports, children's, educational, food production and other rooms. As you know, in accordance with the leadership of P3.1.683-98 "The use of ultraviolet bactericidal radiation for disinfection of air and surfaces in the premises" State system of sanitary and epidemiological rationing Russian Federation Regulates the premises to be equipped with bactericidal irradiaurs for air disinfection, in five categories, depending on the required level of bactericidal efficiency and bulk dose (exposure) for Staphilocjccus aureus.selected as a reference. SBOW Bactericidal Air Sections allow to carry out bactericidal air treatment in all five categories of rooms with the required level of bactericidal efficiency.
As sources of ultraviolet bactericidal radiation, discharge lamps are used, in which radiation containing the wavelength range of 205-31 nm in its composition is generated in its composition (normalization is carried out along the wavelength of 254 nm). Such lamps include mercury low pressure, as well as xenon pulse lamps. Depending on the air flow, the required number of lamps is determined in the device of the bactericidal processing of the air for different categories of rooms. More precisely, the amount and type of bactericidal lamps is selected based on the data on the volume of the processed air, the size of the air duct and the room category.
When applying bactericidal processing devices in the supply and exhaust ventilation system, these devices are placed in the output chamber. SBOW sections are channel devices that are installed in the channel of the rectangular duct and disinfection of air passing through it. Thus, the bactericidal processing of air is carried out directly in the duct channel and does not require special security measures for people in the room. High-precision German equipment german technologies Production, adjustment and testing of the operating parameters provide high quality of the released ventilation equipment.
Thanks to these conditions, a guarantee is provided to the manufactured equipment up to 5 years. The plant is located in the suburbs, so shipment of goods is made during the day from the date of payment. Perhaps the production of equipment for individual order. Directories are available on all products produced.
The quality of manufacture, the flexible marketing policy of LLC "Corf" also rated his clients, among which such well-known firms and organizations as: the office building of the Technonikol holding (Moscow); Network of restaurants "Christmas Trees-Sticks" (Moscow); Network of restaurants "Patio Pizza" (Moscow, Omsk); School of Pilot "Boeing" (Moscow); "Ekaterininsky Museum" in Tsaritsyno (Moscow); Museum of Manor "Ostafyevo" (Moscow); Museum "Hermitage" (St. Petersburg); Concern "Kalina" (Yekaterinburg); Koltsovo Airport (Yekaterinburg); Hotel "Central" (Yekaterinburg); "Promstroybank" (Omsk); Sberbank (Togliatti).
Modern human dwelling is, in fact, a closed ecosystem. Let not be ideal yet, but with the development of technical progress from year to year it is perfect. And to make sure it is enough to simply trace the development of ventilation technology and air purification in residential premises. You can get acquainted with the latest achievements of engineering thought in this segment you can on the website of the company "Breathe at home" https://www.vozduh66.ru.
To date, the most popular and demanded system of ventilation of urban premises of any purpose is a supplier-exhaust. Its advantages, first of all, should be attributed:
In the last advantage, we would like to stop more in more detail. Different residential buildings, Different people are presented to the supply and exhaust ventilation different requirements. And to satisfy these requirements supply-exhaust ventilation Install a variety of air purification systems. They give the attraction-exhaust ventilation universalism of application and a wide range performance characteristics. On the modern market There is a huge number of diverse cleaning systems that differ in between the principle of action. We will list only some of them.
1. The principle of the plasma coatalitic effect.
Cleaning systems working on this principle decompose gaseous pollutants using plasma-chemical and catalytic reactions to elementary gases, for example, to carbon dioxide to water vapor. In addition, this technology allows us to produce ozone, which additionally refreshes the air and clears it from pathogenic microorganisms.
2. The principle of air filtering.
The above technology described is very effective, but it is extremely energy cost. The power of one plasmocatalytic installation may vary from 10 to 50 kilowatts, which may not afford not every consumer. Therefore, for a mass buyer, filtering air purification systems are offered. And this does not mean that they clean the air worse. This is completely wrong. They are just another, the cheapest principle of work, which does not affect the quality of cleaning.
So, for example, Daikin began to equip its seven-point filter cleaning systems, which reaches 7 years!
3. Generators of negative ions.
Another way to clean air is the destruction of complex organic molecules, which are, in most cases, sources unpleasant odor, negative ions.
A modern man pickyly watches his food: is there no GMO in meat, in what conditions this potato is grown than fed a cow, which gave it milk? The philistine places its accommodation with maximum comfort: Repair, soundproofing windows, heated floor. But in all this bustle, it often forgets about the air - so breathing not clean, and rich carbon dioxide, filled with evaporation and particles of sweat with air.
In order to make air into the dwelling clean and secure for the normal life of each family member, it is necessary to organize high-quality ventilation. Modern technologies allow you to make ventilation natural or forced, as well as use the supply ventilation.
Regardless of which the ventilation system operates in the apartment, it must comply with such conditions:
This way of venting out the room is the easiest and most cost. Ventilation canals in the design of the house - this is natural ventilation apartments. Disabled in kitchens, bathrooms, toilets and lattice-equipped exhaust holes.
The air should also fall into the apartment through the open windows and doors, but the tenants are trying to insulate the apartments as much as possible by installing hermetic doors and windows, thereby disturbing the necessary air balance.
Tip! Do not check the level of thrust in the ventilation shaft, bringing a burning match or lighter to it: if gas is gas in the channel, then it is possible to fire.
Remove the clogged ventilation shaft on their own tenants do not have the right: all such work should be carried out by employees of a housing organization specializing in this area. It is blocks that call the most frequent cause Inadequate ventilation work, but it is extremely difficult to get rid of them.
The only thing that the owner of the housing can make is to clean the part of the channel that directly adjacent to the room. Cleansing the remaining channels - the task of specialists.
But sometimes even in the case of good work of ventilation in the apartment can die windows, and the air always remains heavy and sperm. In this case, the problem may lie much deeper: natural ventilation does not cope and needs help. The standard reaction of tenants becomes frequent ventilation with the help of open windowsBut in the cold season, such ventilation threatens colds.
Therefore, experts recommend setting several supply valves or passive ventilators. Some of them are installed near the heating radiators, then the air from the street is immediately included in the air mass circulation system indoors. Modern models There are often equipped, which allows them to work as a supply, and as an exhaust mechanism.
In some cases, natural ventilation for one or another reasons does not cope with the load and does not provide a sufficient flow of air. In this case, experts advise to contact the system of compulsory ventilation of the apartment.
Tip! You should not rely only on your strength and try to independently mount forced ventilation: the master must be performed.
The need to organize compulsory ventilation an apartment is usually associated not only with the actions of the owners of the apartment (, the organization of thermal insulation of the room, hermetic doors), but also with unsatisfactory work of utilities.
Supervision of adequate operation of ventilation channels, timely cleaning of air ducts and normal traction, if it is carried out, it is extremely rare and poor quality.
FACT! Special need for forced ventilation Follow the premises of S. plastic windows: The tightness of the designs disrupts the microclimate of the room, so its ventilation is mandatory.
In the kitchen or in the hall the air duct can be paved above the cabinets
There are two main schemes for the organization of forced ventilation in the premises:
The ideal solution to the accumulation of the apartment becomes the installation of a supply ventilation unit. The standard system of this installation is an ideal mechanism for forced discharge, filtering, and also. Often, electric calorifer is also installed next to the fan, which allows you to adjust the ventilation problem in winter and autumn. In addition, the installation in such a configuration becomes an additional source of heat in the apartment.
Tip! By purchasing an inflow fan installation, pay attention to the models equipped with additional functions: moisturizing, ionization, disinfection. This will save on additional devices.
To ensure the work of such a system in the room, the system of air ducts and lattices should be mounted, with which the purified and heated air will be supplied to the room. The complexity of the implementation of such work makes the optimal process of the structure of all necessary at the stage of construction or overhaul premises.
The necessary sizes of the box are calculated using special tables and formulas, therefore, it is not necessary to carry out such works on the ventilation and air supply and air supply standards.
The inlet installation itself should be mounted outside the residential premises: for example, on the balcony. To do this, the wall is performed in the wall, which allows the fence of outdoor air. After the necessary filtering and cleansing procedures, the resulting warm air is supplied to the apartment's room.
Flat air ducts are laid on the ceiling, later will do suspended ceiling,
which will hide the wiring and pipes of air ducts
A significant disadvantage of such systems is considered a significant increase in electricity costs: the heated air instantly goes into exhaust holes. In order not to deal with similar difficulties, many apartment owners prefer to mount. The advantage of the installation with recovery is the ability to reduce the power to heat due to heat from the air removed. Such a system is much more expensive in the installation, but at the same time it can significantly save on electricity, reduce the load on the power supply and "leave" in the home of the housing, which, with a conventional system, thoughtlessly goes to the street.
FACT! When using a recovery installation, one air flow gives the other only heat, and not odors and contamination: Therefore, you should not be afraid of distribution around the apartment of kitchen or toilet fragrances.
