Systems of ventilation of premises of apartment houses
Because of broad use of modern air-tight construction materials and, not least, windows with double-glazed windows forced-air and exhaust systems of mechanical ventilation of premises begin to have the increasing value. The family of four people allocates a day about 10-15 l of moisture (a bathroom, a shower, kitchen, breath and physical activity). This moisture has to be removed from the room. Otherwise it will be condensed on walls, behind cases and in room corners, the fungus etc. will develop. Harmful allocations from furniture, plastic, carpets, wall panels, cleaners, tobacco etc. which can be allergens are added to it. Even when all harmful allocations influencing quality of air are considered, defining all the same there is a maintenance of CO2. The fulfilled air is characterized first of all by not lowered content of oxygen, and the increased maintenance of CO2. CO2 surplus in air leads to fatigue increase, problems with concentration of attention, to headaches. Anyway, the volume maintenance of CO2 should not exceed 0,1%. The maintenance of CO2 indoors of 20 sq.m in which there are two persons already in half an hour significantly increases and worsens health of people. At application of windows with high zvuko-and heat-shielding properties of the natural air exchange caused by cracks and thinnesses it is not enough for providing a healthy microclimate indoors. The modern design of a window with a multilayered double-glazed window and double consolidation provides air exchange only about 0,2 m3/h. For sanitary and hygienic reasons and (taking into account an extract from kitchen and bathrooms) has to be acting Construction Norms and Regulations inflow of fresh air counting on one room of the standard apartment about 100 m3/h. Thus, normal air exchange at the natural scheme of ventilation requires periodic opening of windows that depreciates their high heattechnical, acoustic and dustproof characteristics. The ventilation system designation - to provide sanitary and hygienic conditions for stay in the person in compliance about Construction Norms and Regulations for what ventilating devices have to provide without priotkryvaniye of windows intake of the fresh purified air in premises and removal of the fulfilled air through kitchens, toilets and bathrooms. Need of use of filters of air causes use of fans in system of ventilation for overcoming of hydraulic resistance of filters.
