How nice it is to sit in a warm armchair near the fireplace in the season of impending cold weather, wrapped in a blanket and sipping warm fragrant tea, having leisurely conversations with friends or family, reading your favorite book worn to holes or watching a good old movie! Unfortunately, for many this remains just an unrealizable dream: no matter how hard the owner tries to insulate and secure the home, and the hostess tries to make it as comfortable and cozy as possible, something is missing. The humidifier does not help: the windows sweat, the silicone seal turns black, the wallpaper peels off and exposes the walls covered with black mold, dampness is felt on the skin, clothes absorb it, unpleasant odors quickly spread around the house. If this describes your home, then know that the ventilation duct is not working. Start repairing, otherwise you risk your he alth.
What is a ventilation duct?
People who are accustomed to being interested in all the little things of their improvement, probably know about ventilation in their apartment or private house. The ventilation duct is the one that is locatedvertically (there are two or more of them) and ensures the natural and normal movement of air in the room. To understand the principle of ventilation, you need to remember the lessons of physics: air moves from an area of high pressure to an area of \u200b\u200blow pressure, and warm air is lighter than cold air, therefore it moves vertically upwards. Due to the normal operation of this system, we do not feel humidity or, conversely, dryness, and the optimum temperature is maintained in the room. An important point: with too good ventilation, the heat loss of housing can be about half, but when installing a special valve, they will be significantly reduced. The latter are also needed for plastic euro windows. Plus, ventilation is provided by hoods in the kitchen (and they will remove burning, smoke and unpleasant odors that tend to "settle" on clothes and hair), as well as fans, they will be very useful in the summer when you want a chill. Don't forget modern sealed window systems and air conditioners.
Inspection of ventilation ducts by yourself

It is not necessary to call specialists, just find the grate under the ceiling (this is the ventilation hole), slightly open the door or window. Take a very thin and light sheet of paper (napkins work best) and place it on the grill. If everything is normal, it will retract, and when the air is stagnant, it will fall.
Ventilation duct. Alternatives
Of course, many may not like the fact that the installation of an air duct can greatly spoil the beauty of the house. Imagine: right in the middle of an elaborate wall or ceiling, a barred hole flaunts. There are also alternatives. Forced ventilation is a rather complex system of branched air ducts, as well as valves, noise suppressors, filters, and so on. But it can cost you a pretty penny, because you need a fairly large amount of energy. Therefore, it is desirable to install a recovery system. Infiltration - ventilation through natural cracks in windows and doors. Ventilation is good for he alth, but it requires a lot of heat, which is gone for a full cycle of air replacement. In addition, you run the risk of catching insects or seeds of plants that cause allergies. Remember that installing ventilation will bring comfort, warmth to your home, protect your life and he alth, and provide a number of other benefits. Cosiness and warmth to you!
