A single-side ventilation device for forming air pool airflow organization and its control method

Abstract

The invention discloses a single-side ventilation device for forming the airflow organization of an air pool and a control method thereof. Round; the two vertical planes of the ventilation duct are respectively parallel to the two walls at the corner of the room where it is installed; the air supply port at the top of the ventilation duct is connected to an external air supply device; the top of the room is also provided with an exhaust device , the exhaust device communicates with the room. The device of the present invention reduces the amount of mixing 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 uses the air supply port and the two side walls of the corner to form a double-sided attached jet The unique air supply method can maximize the effect on the entire work area, thus ensuring the freshness of the air in all work areas, so that the air quality and temperature and humidity in the work area can meet the comfort requirements.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a single-side 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 t...

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
