Chronic fatigue and stress are a common problem of residents of megacities. Although their reasons are hidden in the simplest, we can say elementary things. For example, in bad ecology – a lack of oxygen and a large number of harmful impurities that are contained in the air. Throughout its life, a resident of the big city has been influenced by these harmful factors – on the street, in the office, and, most importantly, at home, during sleep and rest and rest. If the windows made of wood, then the air influx will be carried out with the help of cracks in the frames, and if from plastic, we can say that it does not happen at all. Periodic ventilation is a drop in the sea compared to the needs of our body (from 30 m3 of fresh air per hour). In the absence of a given amount, the body begins to consume “worked out” air, saturated with sufficiently harmful toxins. Constant staying in such conditions equivalent to a slow, gradual suicide. In addition to the fact that natural ventilation does not cope with the task of air exchange, it also depends quite strongly on the external conditions – the speed of wind and temperature. Supporting air flows in the house or apartment may solve the problem of air flows. The principle of the device of such ventilation is quite simple, for it it is not necessary to perform the air duct system and conduct complex calculations. The influx of air mass is performed due to the through canal, which is performed in the wall. Performed by special equipment, a pipe is inserted into this channel, and in it noise is a heat insulation. The heads are issued using decorative grilles, and the supply ventilation is ready. Now she will constantly supply your room with fresh air, and the cost of its execution is simply incommensurable with benefit.
