How to improve natural ventilation in the house Bashny.Net

Modern man began to isolate themselves from the environment. New building and insulating materials, which are unattainable in the earlier period properties, and innovative technology of construction of houses do not give a single chance precipitation, winter cold or summer heat to disturb the comfort of the homeowner. However, the price you have to pay for all this, is quite high. Inside buildings collect and store a whole bunch of harmful for the body chemical compounds and substances that produce household items, building materials, used in everyday life chemistry the man himself. Join this no less harmful dust, fungi and mold. As a result of normal home air is several times more dangerous, dirtier and outdoor. To save a person from serious consequences of the inevitable inhalation of such "cocktails" may only ventilation, which quickly will remove the "waste" mixture and replace it with a sufficient portion of fresh air.

It would be a mistake to assume that effectively only works with forced ventilation. Well-designed natural systems are operated by all the rules, perfectly cope with their task and provide the room with clean air. Natural ventilation, unlike forced, does not require the installation of special equipment, since the replacement of the air inside the building is under the influence of gravitational pressure.





The principle of operation of such a system is extremely simple. The air inside buildings often warmer than what is outside. Accordingly, it becomes more rarefied and light, resulting in rises upwards and through the ventilation channels is expelled. In its place from the street penetrate the denser layers of air that tend down and actively replacing updrafts "waste" mixture. Works like gravitational pressure, the main driving force of natural ventilation. Her help usually comes wind influence, enhance the circulation of the air flow. The higher the wind speed and the greater the temperature difference between outside and inside the building, the better the system works.

Properly designed natural ventilation involves no fans. Ventilation is via the vents or the window sash, doors, vents in the basement, ventilation channels and different slots. Matters and the material of which erected the building. For example, a wooden block can "breathe", thereby maintaining a circulation of air, while brick or stone is completely deprived of this opportunity. There are two types of natural ventilation. Spontaneous system requires no human intervention. She works exclusively due to changes in wind speed and changes in pressure and temperature.





More difficult is the organized natural ventilation. It presupposes the existence of ducts of different diameters, placed at different heights. In pipes of such extractors can be mounted in a special damper, which can adjust the output to the outside and incoming air flow. The height and cross-sectional area of the ducts are calculated individually for each building. Individually is solved and the subspecies system, which can be aeration, longline or gravity.

If natural ventilation was designed incorrectly or as a result of installing energy-saving window systems and insulating walls were breached infiltration process, be sure to adjust the air in the room. This can be done with the assistance of the installation supply valves. They are most often placed in the profile window system. They can be mounted over a window or casement frame or can be mounted in a lever-valve. The device can be placed on the previously mounted window systems or integrated into new profiles.





Another option is to install the supply valve the wall type. This system represents a branch pipe, which passes through the wall. Both ends of the device are closed by protective grilles. Advanced hardware may have sound-absorbing labyrinth and camera with filters, purifying the air supplied. The inner cage of the device can be opened and closed. Some models are equipped with special sensors for humidity and temperature, automatically regulating the degree of closing/opening of the grate. Regardless of the type of intake valves effectively improve natural air circulation.

Natural ventilation in modern construction is rarely used. The reason for this was the dependence of the power system from natural factors, low rates of air exchange and lack of stability. However, it could exist. After all, natural ventilation is more economical of their coercive counterparts. It requires no special equipment, cost of maintenance and electricity. Moreover, equipped with such a system the room more comfortable because of the low rate of movement of airflow and lack of noise. With proper design and installation of natural ventilation will work efficiently and effectively. published
