Background
In the indoor ventilation technology, the traditional mixed ventilation mode is characterized by high speed, large momentum and turbulent air supply, and is widely used until now because the mixed ventilation mode is easy to arrange in a building space and does not occupy a lower building space (working area). However, during the air supply process, a large amount of indoor air is sucked, the working area is generally in a return air or exhaust air environment, and the ventilation efficiency and sanitary conditions are relatively poor.
In view of this, the inventor of the present application has proposed a cylindrical surface attached jet air supply method (as shown in fig. 8) in early patent CN101988731B, in which an air supply port and an annular static pressure box of the air supply port are installed at the top of an indoor cylinder, the air outlet of an annular slit is vertically downward, and an attached effect is formed by the cylinder, so that the air supply flow is sent to the ground, and thus entrainment of indoor air by the air supply is reduced, and the air quality and energy saving effect of the mixed top air supply are improved.
However, this method has found the following disadvantages during experimental and practical use:

2. the air supply opening is an annular slit air opening encircling the cylinder, the whole shape is fixed, the air outlet is in a state and mode of being vertical and downward, and the self-regulation of the wind speed and the wind direction cannot be realized;
3. in the comparative test of embodiment 1/3, an air supply valve or a fan power gear is additionally and independently arranged to adjust the air speed of the air outlet of the annular strip gap; in the comparative test of embodiment 1/2, two sets of static pressure boxes with different sizes are needed to be respectively designed to adjust the distance between the annular strip seam air outlet and the cylindrical surface, so that the method is not beneficial to industrialized manufacturing, and has high cost and poor adaptability;
4. the vertical adherence of cylinder setting's condition can only be aimed at, the mode is unique, because of the difference of actual operating mode such as room space size, cylinder arrangement position, with air supply target area or target crowd distance, only the vertical adherence of cylinder and the single mode that can not adjust can not be applied to complicated scene, for example room space is bigger, or when the cylinder kept away from air supply target area or target crowd, the air supply effect is too poor, or the cylinder adopts hiding the setting again and can't arrange vertical adherence, can't solve the air supply problem.
