Bilateral ventilation device for forming air tank air distribution and control method thereof

Abstract

The invention discloses a bilateral ventilation device for forming air tank air distribution and a control method thereof. The bilateral ventilation device comprises two ventilating ducts which are vertically mounted on opposite-side wall corners or same-side wall corners on the top of a room, wherein the ventilating ducts communicate with the room; the cross section of each ventilating duct is in the shape of one fourth a circle; two planes, in the vertical direction, of the ventilating ducts are respectively parallel to two walls on the wall corners of the room in which the ventilating ducts are mounted; top-end air-supply outlets of the ventilating ducts are externally connected with air supply devices; and an air exhaust device which communicates with the room is further arranged on the top of the room. According to the bilateral ventilation device disclosed by the invention, mixing amount of air and indoor polluted air or hot air is reduced, and the quality of supplied air is improved; a formed cold air tank is relatively wide in coverage, and the whole working region is acted to the greatest extent by utilizing an air supply mode of forming double-faced wall attachment jet by virtue of the air supply outlets and two side walls on the wall corners, so that the freshness of the air in the whole working region is guaranteed, and the quality and the temperature and humidity of the air in the working region meet comfort requirements.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a double-sided ventilation device for forming an air pool airflow organization and a control method thereof. Background technique [0002] After experiencing the hazards of "soot pollution" and "photochemical pollution", modern people are suffering from the third pollution mainly caused by "indoor air pollution". According to research by American experts, the degree of indoor air pollution is 2-5 times worse than that of outdoors, and can even reach 100 times in special cases. To improve indoor air pollution, the most direct and effective way to improve indoor air quality is to improve indoor air circulation, accelerate the discharge of indoor polluted air, and accelerate the injection of outdoor fresh air. Because displacement ventilation can obtain higher air quality, higher thermal comfort and higher ventilation efficiency in indoor working areas, displacement ventilation is currently ...

Problems solved by technology

However, there are problems in the specific implementation. The air supply port of the invention is rectangular. Although it has been attached to two side walls, under the same air supply volume and air supply speed, the rectangular air supply port is not compatible with the above-mentioned slit profile. Like the traditional ventilation system, the air flow sent out has a large contact area with the surrounding indoor air, which will cause the air supply air to mix with indoor polluted (hot) air earlier, reducing the quality of the air supply
