 Interesting article: Breath-breath test!Comfort indoor climate is determined by two key parameters: temperature and humidity. But if the first is clear (the temperature of people able to accurately determine on their feelings, and the thermometer is almost in every house), then with moisture, everything is more complicated. Typically, a change of humidity can be judged only on indirect indicators - such as the moisture condensation shows on the windows.The mechanism of education condensate is: air, soprikasayas with a cold surface (such as glass windows in the winter) and cooled. However, its ability to dissolve in a moisture decreases, but the number has already been dissolved moisture remains the same, resulting in an increase in its relative humidity. If achieved 100% humidity, the cold surface provided "redundant" the moisture that cold air can not in itself provide (the same steam glass jar, remove from the refrigerator). The temperature of the surface, where it begins to fall condensate, called "dew point". Comfortable accommodation considered to be the temperature of 20 ° C and humidity of 55%. In such settings, the dew point is 10,7 ° C. However, if the humidity is increased to 80%, the dew point will have 16,4 ° C, ie Condensate will subside even on very warm glass. Thus, there are two ways to combat the formation of condensate: a temperature increase domestic glass and the maintenance of normal humidity in the room. The first applies only when the order window when you select a profile with good thermal characteristics. It should be noted that the perimeter of double-glazed windows are aluminum frame, remote, well-conductive cold, so the internal temperature of glass around the edges of insulating glass unit will be several degrees lower than estimated. So far, unfortunately, not developed tehnoldogy to use other, less transcalent than aluminum, the material for the framework. The second path involves the continuous provision of adequate ventilation in the room. Reaches that with the help of ventilation. For modern windows aeration is much more important than for the previous simplest wooden. "Concentrated" airing when periodically for five to ten minutes, people leaving the room, opening with a window, requires a fairly large opening casement. Permanent ventilation when a valve is constantly slightly ajar, requires a small leaf (eg View), which must be swivel-folding opening, equipped with a gap provetrivaniem and, if possible, additional elements fitting fixing stvorku ajar in various positions. Naturally, any window of opportunity to provide ventilation, but that was not enough to achieve comfort. Recently, increasing receives the so-called dose ventilyatsiya.V design window provides an element of ensuring the flow of a small, pre-calculated the amount of outdoor air at the closed window. This allows the normal climate in the room when indoors for a long time closed all the windows (for example, on vacation). The fact is that the model apartment ventilation involves a certain amount of air inflow through the window. On sanitation, air plastic windows in a residential area (size 1,5 x 1,5 m) at about 9 m 3 / hour. Accordingly, the window with dosed ventilation air must pass in two - three times smaller than this value. In the PVC windows with secondary thickening the air usually passes through a complex system of holes. The most original and here is a simple ventilation system dosed "Comfolip" profile TROCAL 900. The boxes with two seals porch, a good decision can be described as an additional device "Regel Air", which is built in the PVC-profile of several brands. Both of these design provides a constant flow of air regardless of the pressure of the wind. The required amount of air is heavily dependent on many conditions: weather, season, time of day, etc., So for convenience to better provide for ordering the windows all possible types of ventilation - their share of the total value of the window is not so great. |
