[0055] like Figures 1 to 14 As shown, the high-efficiency filter air outlet for the air conditioning system in this embodiment includes: a static pressure box 1, a high-efficiency filter 2, and a diffuser 3.

[0056] The static pressure chamber 1 includes: a rectangular shell 11, an upper panel 12, and a lower base plate 13.

[0057] The bottom plate 13 and the top plate 12 are respectively disposed at the inlet end and the outlet end of the rectangular shell 11, and are respectively fixedly connected to the rectangular shell 11.

[0058] The bottom plate 13 is provided with a square air inlet 131.

[0059] The high-efficiency filter 2 is installed on the inner side of the top plate 12 and extends into the rectangular housing 11.

[0060] The diffuser 3 is fixed to the outer side of the upper plate 12 by screws.

[0061] The diffuser 3 is provided with multiple first air outlets 31 and multiple second air outlets 32.

[0063] Multiple second air outlets 32 are arranged around the outer perimeter of the first air outlet 31. The second air outlets 32 are inclined, and the angle between the air supply direction of the second air outlet 32 ​​and the central axis of the rectangular shell 11 is an acute angle, so that the air supplied by the second air outlets 32 arranged around the first air outlet 31 diffuses to the outer perimeter of the diffuser plate 3, making the supplied airflow more uniform.

[0064] In this embodiment, the high-efficiency filter air outlet for the air conditioning system is located at the air outlet of the air supply duct of the air conditioning system.

[0065] The air (airflow) delivered by the air conditioning system enters the rectangular shell 11 through the air inlet 131 of the bottom plate 13. After being filtered by the high-efficiency filter 2, it is delivered to the indoor space of the clean room through the first air outlet 31 and the second air outlet 32 ​​of the diffuser plate, ensuring that the airflow entering the indoor space reaches the required cleanliness. The airflow delivered from the first air outlet of the diffuser plate moves forward along the axis, and the airflow delivered from the second air outlet of the diffuser plate diffuses to the surroundings, so that the delivered airflow is evenly distributed in the clean room (indoor space), which can avoid short-circuiting or eddy current phenomena in the airflow.

[0066] It is not difficult to see from the above that the high-efficiency filter air outlet for the air conditioning system in this embodiment is provided with a static pressure box, a high-efficiency filter and a diffuser plate. The static pressure box includes a rectangular shell, a top panel and a bottom panel. The bottom panel and the top panel are respectively located at the inlet end and the outlet end of the rectangular shell. The high-efficiency filter is installed on the top panel.

In this embodiment, the high-efficiency filter air outlet for the air conditioning system is located at the end of the air supply duct of the air conditioning system and can be embedded in the ceiling or wall of the cleanroom. The air (airflow) delivered by the air conditioning system enters the rectangular housing through the air inlet of the bottom plate, and after being filtered by the high-efficiency filter, it is delivered into the cleanroom through the first and second air outlets of the diffuser plate. The high-efficiency filter can effectively filter out dust particles, microorganisms and other pollutants in the airflow, ensuring that the airflow delivered into the cleanroom meets the required cleanliness standards. Moreover, the second air outlet of the diffuser plate diffuses the airflow in all directions, making the delivered airflow evenly distributed in the space of the cleanroom, making the cleanliness of the entire cleanroom more uniform, and avoiding short-circuiting or eddy current phenomena in the airflow.

[0070] The air guide plate 4 is opposite to the air inlet 131 of the lower base plate 13. The airflow entering from the air inlet 131 of the lower base plate 13 is guided by the guide hole 41 of the air guide plate 4 and then reaches the high-efficiency filter 2, making the airflow more uniform.

[0071] Furthermore, in this embodiment, the high-efficiency filter air outlet for the air conditioning system has a connecting bracket 132 on the inner side of the bottom plate 13.

[0072] The connecting bracket 132 is L-shaped at a right angle. The guide plate 4 is fixed to the connecting bracket 132 of the lower base plate 13 by screws, and the guide plate 4 and the lower base plate 13 are arranged parallel to each other.

[0073] Optional, such as Figure 9 and Figure 10 As shown, in this embodiment, the first air outlet 31 of the diffuser plate 3 for the air conditioning system is a round hole, and the air supply direction of the first air outlet 31 is parallel to the central axis of the rectangular shell 11.

[0074] The longitudinal section of the second air outlet 32 ​​of the diffuser plate 3 is trapezoidal, and the second air outlet 32 ​​is inclined. The air supply direction of the second air outlet 32 ​​forms an acute angle with the central axis of the rectangular shell 11. The second air outlets 32 arranged around the first air outlet 31 are inclined outwards respectively. The multiple second air outlets 32 are arranged in the shape of louvers around the first air outlet 31, so that the air (airflow) delivered from the diffuser plate 3 diffuses in all directions, making the air distribution more uniform and avoiding short circuit or eddy phenomenon in the airflow.

[0075] Optional, such as Figure 2 , Figure 6 , Figure 11 , Figure 12 and Figure 14 As shown, in this embodiment, the high-efficiency filter air outlet for the air conditioning system has connecting ribs 121 on the inner walls of the upper panel 12.
