Za tightly closed window

What Russian would not like to replace the old rotted through wooden frames on convenient, warm, shumozaschitnyie and modern double-glazed windows not requiring burdensome care in smooth beautiful covers? However practice of their installation in our apartment houses and public buildings, otrodu not having a forced-air and exhaust ventilation, has shown, that tightly closed windows sparkling by the European lustre do not approach them by definition. In our houses ventilation of premises occurs naturally exclusively because windows are no closed tightly. Through leaky driven wooden frames in rooms that necessary quantity of air which allows the person to feel comfortable acts just. And fulfilled air leaves on street through lattices vyivodnyih the channels which are available, as a rule, on kitchen, in a bathroom and in a toilet.

As soon as instead of old wooden frames in such houses establish the profile designs of double-glazed windows tightly closing window apertures, inflow of fresh air completely ceases, so, and the extract ceases to work. In such premise steams of carbon dioxide and other harmful impurity are very fast accumulated, and also level of relative humidity raises considerably. It is received, unconditionally, warmly and silently, but it is very stuffy. As a result on brand new double-glazed windows in a cold season the condensate acts, and on slopes there is a mould.

Certainly, people with this phenomenon struggle by usual airing of premises. But the paradox consists that as soon as they slightly open that or a different way a window shutter questions energosberezheniya and shumopoglascheniya for the sake of what, actually, and eurowindows have been thought up, lose at once the decision. And it is necessary to consider, that for the account of the window completely opened on some time in general it is necessary to forget about airing. Zalpovaya hyperventilation, especially when it is cold, rescues all for some minutes, and then very fast it becomes again stuffy. It is a little bit easier to struggle with this phenomenon by the system of regular slot-hole airing by means of special window accessories — opening terminators. The small draught at the expense of inflow of fresh air will solve a closeness problem, the truth, can create other problem connected with health. And, besides, through leaky closed window in a premise street noise will rush.

There is even a method a little to improve a situation is to establish specially designed ventilated profiles or partially air-penetrable uplotniteli. These systems of "microventilation" allow to lower probability zapotevaniya windows, not infringing parametre shumozaschischennosti, but, unfortunately, all the same do not supply sufficient inflow for comfortable existence of external air.

For today much more comprehensible variant solving a question of ventilation of premises behind tightly closed window apertures, installation of the special ventilating valves which have been built in in covers of windows is. Such valves name pritochnyimi the window systems, optimal of which is production of French firm "Aereko" of system "Gigro". System «Aereko« represents a small plastic case under colour of a frame which insert into a crack cut, for example, in the top part of a window. The principle of its work is based on the control of level of relative humidity, as basic indicator of impurity of air indoors.

Such pritochnyie systems establish on tight window frames of any kind (PVC, a tree, aluminium) or is direct on outside walls. Supervise relative level of humidity the special gauges representing bunches of tapes from a polyamide fabric. When humidity raises or goes down, this fabric extends accordingly or compressed, putting in action the mechanism zaslonki pritochnogo systems. It is possible to tell, that automatic maintenance of the necessary inflow for comfortable existence of fresh air through specific gigroklapan which work does not require availability of the power supply is received. And apartment rooms are ventilated selectively depending on presence at them of tenants. For example, when all are in a drawing room, and bedrooms stand empty the drawing room is ventilated in bolshey degrees. And at night everything, naturally, occurs on the contrary. Especially it is convenient, if in the house the two-trumpet system of heating is established. Then, except maintenance of normal ventilating conditions, there is still a possibility of reduction of costs for heating. But for this purpose installation of the additional equipment is, of course, necessary together with pritochnyimi and exhaust gigroreguliruemyimi systems «Aereko«: the metre of hot water on an input and radiators of heating with the thermostat. Such system simply works. When in the house anybody is not present also humidity level small, inflow of fresh air to a premise decreases. It in turn leads to rise in temperature which causes the operation of the thermostat leading to reduction of the cost of hot water and accordingly of a payment for heating. It is necessary to tell, that in some climatic zones of Russia from Kaliningrad to Novosibirsk three-year operating experience of similar systems is already accumulated. So that, quite probably, in the future with the purposes of rescue from an energy crisis menacing to us, all of us will pass to principles of automatically adjustable systems of ventilation and heating.

Pritochnyie systems «Aereko« are manufactured two types. For installation directly in windows apply updatings EMM and ENA, and to installation in a wall — ENT. Window updatings of systems in installation are very simple. They malogabaritnyi, are established both at window manufacturing in shop, and at already ready window without dismantle and double-glazed window replacement, and the thickness of a double-glazed window can be any, a profile material — too. The air stream from pritochnogo systems EMM can be inclined or vertical — depending on a situation. If to establish it in the top part of a window and to direct a stream of cold air to a ceiling draughts in a zone of a finding of people it will not be simple. Still it is necessary to notice, that, even at complete opening of the valve, the index of clearing of transport noise makes size from 33 to 42 dB (depending on performance. And it thus, that the window from PVC has 30-35 dB () in the closed condition.
