Ventilation device forming airflow organization of air pool, and control method of ventilation device

Abstract

The invention discloses a ventilation device forming an airflow organization of an air pool, and a control method of the ventilation device. The ventilation device comprises a ventilation duct which is vertically mounted at the top of a room and close to a side wall of the room, wherein the ventilation duct communicates with the room, and the cross section of the ventilation duct is semicircular; the plane of the ventilation duct in the vertical direction is parallel to the side wall of the room, on which the ventilation duct is mounted, an air supply outlet in the top end of the ventilation duct is in external connection with an air supply device; an air exhaust device is also arranged at the top of the room, and communicates with the room. Through the adoption of the ventilation device disclosed by the invention, the mixing amount of the air in the ventilation device with indoor polluted air or hot air is reduced, and the air supply quality is improved; the coverage of a formed cold air pool is extensive, and the supplied airflow is applied to a whole working region at the greatest extent, so that the air freshness of the whole working region is guaranteed; therefore, the air quality of the working region and the temperature and humidity of the working region meet requirements for comfort.

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...

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
