[0002] With the diversification of social life, there are more and more architectural projects with stepped seats, such as concert halls, conference rooms, cinemas, and gymnasiums. For such projects with large spaces and large structural spans, HVAC terminals often use seat air supply. This method effectively sends the treated air to the audience area first, and the method belongs to displacement ventilation. There is no obvious sense of wind in the audience area, and the comfort is strong. The energy-saving effect of seat air supply is significant. Without the need to treat the temperature of the entire large space to the design temperature, the comfort of the audience area is met by displacement ventilation, which greatly saves energy consumption and unit investment.

[0036] Reference Figure 1-Figure 6 As shown, the utility model provides a specific implementation method for a seat air supply column, including a plurality of air outlet ducts 10 connected to an air conditioning air supply system, which are opened on a floor;

[0037] The steel casing 20 is a hollow cylinder and is sleeved inside the air outlet 10;

[0038] The platform 30 is located on the floor slab of the completed building surface, and openings of the same cross-sectional shape are opened at corresponding positions of the platform 30 and the air outlet duct 10, so that the platform 30 can discharge air;

[0039] The adjusting turntable 40 and the fixed blade disk 50 are mounted in the steel casing 20 from top to bottom, so that the adjusting turntable 40 can rotate around the central axis of the steel casing 20. The fixed blade disk 50 is installed at the bottom of the adjusting turntable 40 and is connected to the air outlet 10.

[0040] The air supply column 60 , which can adjust the position of the air outlet, is installed on the top of the adjustment dial 40 of the platform 30 , so that the air supply column 60 rotates synchronously with the adjustment dial 40 .

[0041] The utility model adjusts the fixed blade disk 50 connected to the air conditioning air supply system by adjusting the turntable 40, so that the air inlet area at the bottom of the air outlet 10 becomes smaller or larger, thereby realizing the adjustment of the air volume and the horizontal change of the wind direction; secondly, the vertical adjustment can also be realized by toggling the shutters on the air supply column 60, that is, according to the end air supply situation, it is convenient for the debugging personnel or the audience to adjust the air supply volume conveniently, and the air supply angle can be adjusted up and down according to the individual comfort of the audience, so as to meet the personalized needs of the personnel; provide better comfort conditions for watching movies; improve the overall quality of concert halls, conference rooms, cinemas, and gymnasiums. It is suitable for wide application in seat air supply air conditioning systems. The details are as follows;

[0042] The adjusting dial 40 includes a horizontal portion 401 and a vertical portion 402 . The vertical portion 402 is disposed in the middle of the bottom of the horizontal portion 401 , so that after the adjusting dial 40 is mounted on the air outlet 10 , the horizontal portion 401 is exposed on the platform 30 , while the vertical portion 402 is located inside the steel casing 20 .

[0043] The horizontal portion 401 of the adjustment dial 40 can be manually rotated so that the vertical portion 402 can be rotated in the air outlet 10, which is convenient for manual operation.

[0044] Further, the fixed blade disc 50 comprises blades 501 and a rotating shaft 502, and the blades 501 are of a certain number and are mounted on the rotating shaft 502 at a preset angle A;

[0045] A fixing rod 503, the top end of the rotating shaft 502 is installed on the top of the air supply column 60 through the fixing rod 503;

[0046] The number of the first toggle shaft 504 and the second toggle shaft 505 is half of the number of the blades 501 and they are parallelly distributed on the upper and lower surfaces of the blades 501. One end of the first toggle shaft 504 and the second toggle shaft 505 is fixed to the inner wall of the vertical portion 402 of the adjusting dial 40.

[0047] Among them, the preset angle A is 100°-160°.

[0048] By rotating the adjustment dial 40, the first toggle shaft 504 and the second toggle shaft 505 begin to rotate around the rotating shaft 502. Since the blade 501 is designed to be inclined, when the first toggle shaft 504 and the second toggle shaft 505 rotate, the blade 501 will also be rotated, so that two adjacent blades 501 are overlapped and stacked. The gap between the two adjacent blades 501 is the air outlet area. The more the overlapping area of ​​the two blades 501 is, the larger the air outlet area is, and the greater the air volume is, which simultaneously drives the air supply tube 603 to rotate and changes the horizontal direction of the air outlet.

[0049] Furthermore, the first shifting shaft 504 and the second shifting shaft 505 have different lengths.

[0050] In one specific embodiment, the first toggle shaft 504 is shorter than the second toggle shaft 505 , or the first toggle shaft 504 is longer than the second toggle shaft 505 , thereby increasing the contact area between the first toggle shaft 504 or the second toggle shaft 505 and the blade 501 and facilitating the toggle of the blade 501 .

[0051] In one specific embodiment, the thickness of the end of the blade 501 close to the rotating shaft 502 is greater than that of the other end, so as to facilitate the first shifting shaft 504 and the second shifting shaft 505 to be shifted.

[0052] The utility model also includes a fireproof rock wool layer 70, which is closely attached to the inner wall of the steel casing 20 and is located between the vertical portion of the adjusting dial 40 and the steel casing 20. The fireproof rock wool layer 70 is made of fireproof rock wool, has good sound absorption effect, good thermal insulation performance, and excellent corrosion resistance, moisture resistance, fire resistance, and heat insulation performance.

[0053] As a possible specific implementation of the utility model, the air supply column 60 includes a plurality of louvers 601 and a fixing frame 602, the fixing frame 602 is a hollow cylinder, the louvers 601 are parallel to each other on the outer surface of the fixing frame 602, and the louvers 601 are rotatably connected to the fixing frame 602;

[0054] The air supply tube 603 is covered on the outside of the fixing frame 602 and connected to the fixing rod 503 .

[0055] Furthermore, the air supply tube 603 is a cylindrical structure with a closed top and an open bottom, and two symmetrical air supply ports 631 are opened on the side of the air supply tube 603 .

[0056] Furthermore, the air outlet 631 is in a porous mesh shape.

[0057] The utility model adjusts the vertical direction of the air outlet direction by toggling the louver 601 on the air supply column 60 so that the louver 601 can be rotated up and down. The wind coming out of the air outlet 10 passes through the fixing frame 602, is blown out along the inclination direction of the louver 601, and is finally discharged from the air supply port 631 of the air supply tube 603. If the louver 601 is level with the platform, the air is discharged horizontally. Otherwise, the air is discharged upward or downward. According to the air supply situation at the end, the debugging personnel or the audience can conveniently adjust the air supply direction.

[0058] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
