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

The invention discloses a ventilation device for forming an air pool airflow organization and a control method thereof, comprising a ventilation duct vertically installed on the top of a room and close to the side wall of the room, the ventilation duct communicates with the room, and has a semicircular cross section The plane in the vertical direction of the ventilation duct is parallel to the side wall of the room where it is installed; the air supply port at the top of the ventilation duct is connected to the air supply device; the top of the room is also provided with an exhaust device, and the exhaust device communicates with the room . The device of the present invention reduces the mixing amount of it with indoor polluted air or hot air, and improves the quality of the air supply; the formed cold air pool has a wider coverage, and the air supply air flow can act on the entire working area to the greatest extent, thereby ensuring that all The freshness of the air in the working area makes the air quality and temperature and humidity in the working area meet the comfort requirements.
Description
technical field [0001] The invention relates to a ventilation device, in particular to a 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 the most wide...
