Fan. Optimal variant

The problem of inadequate ventilation, there often. We feel it myself, but not always correctly determine the source of the problem. Stuffiness, humidity - hence the bad mood, apathy. We have managed to dissociate itself from the street noise and smog plastic windows. However, replacing old wooden windows with plastic, we have deprived themselves of the natural flow of fresh air. Air flow problem can be solved at the stage of repair or alterations, and after finishing the interior. The simplest solution - Supply valve type RTL. Breaks through a hole in the wall of the living room. In this hole is mounted inlet valve. RTL valve consists of a duct with a diameter of 100mm, outdoor (street) grids and distribution device having a filter, a flow controller (check valve) and sound-absorbing plate. Advantages of low cost system can be easily mounted ease of control minus system works effectively only if there is a good natural or mechanical exhaust is not heated during the cold season. More functional and efficient - wall supply unit, such as "Marta", "Sonair A". It is mounted on the wall of the dwelling on the hole diameter of 120mm. Advantages of simplicity in installation requires no wiring duct channel, ie, lowering ceilings effective cleaning system supply air pleated filter delays in the air allergens, dust, lint, etc. charcoal filter removes odors, fumes electric (0,8 kW) heating fresh air in the cold season can adjust the power flow of air 40.80.120 cu.m / h low-noise 22.3 / 33/38 dB opportunity to clean (filtered) air indoors in a recirculation mode protection against insects (flies, mosquitoes). Disadvantages of Multi-channel virtually no air supply and the supply and exhaust unit "ALFA" capacity from 800 to 5000 m? / h. Device "ALFA E" electrically heated air. Device "ALFA W" with water heated inlet air. Device "ALFA E cool" with electric heating and cooling air. Device "ALFA W cool" with the water heated and cooled air flow. Exhaust air unit "ALFA S Pluses system versatility Low noise Easy operation and programming of the system reliability Cons Need wiring duct channel, which is not always possible to consider the above air supply system will help solve the problem of ventilation of any room, apartment, cottage or restaurant. Rarely encountered types of solutions, most projects have their own characteristics, taking into account the norms of ventilation and the wishes of the customer. We have examined the problem in fresh air. But we must remember that the correct, appropriate standards of air exchange and ventilation - it's fresh and exhaust hood (used) air. Exhaust, often natural ventilation is always laid originally in the building. We can make it more efficient and automated. To do this, there is a series of exhaust domestic fans that show a low noise level, modern design and ease of management, the ability to connect sensors: a timer, humidity sensor, motion sensor. Want to stress - a person spends in a room of about 80% of their time. On the quality of the air we breathe, we depend for our well-being, health and the health of people close to us.
