Referring to fig. 1 and 6-11, the present application provides an air conditioning module 1 including an air supply duct 11, a return duct 12, a baffle 14, and an air conditioning case 15. The air supply duct 11 has an air supply opening communicating with a controlled environment. Referring to fig. 6, the return air duct 12 includes a return air inlet 121 and a dust exhaust opening 122 penetrating in the thickness direction of the duct wall. The dust discharge port 122 is disposed adjacent to the return air port 121. The baffle 14 is rotatably connected to the inner wall of the return air duct 12 and is located between the return air inlet 121 and the dust discharge opening 122. The air conditioning box 15 is connected with the air supply pipeline 11 and the return air pipeline 12 at two ends respectively. The air conditioning module 1 has a cooling mode and a dust removal mode. In the cooling mode, the shutter 14 is rotated toward the dust discharge port 122 to cover the dust discharge port 122, air is introduced into the air conditioning case 15 through the return air port 121, and the cooled air is discharged to the controlled environment through the supply air port. In the dust removal mode, the baffle 14 rotates to the side of the return air inlet 121 to cover the return air inlet 121, and air reversely enters the return air duct 12 to be cleaned through the air conditioning box 15 and is discharged through the dust discharge port 122 to clean dust in the return air duct 12.

The application provides an air conditioning module 1 can purify the interior air of controlled environment, and air temperature and humidity are adjusted, and can be clean to return air pipeline 12 through changing air conditioning module 1's mode of operation to the absorptive dust in the clean return air pipeline 12 reduces the peculiar smell in the air current that is blown out by air supply pipeline 11. And the reverse airflow is utilized for cleaning, a cleaning device is not required to be additionally arranged, the structure is simple and convenient, and the cost is reduced.

As shown in fig. 11, in some embodiments, the air conditioning module 1 further includes a filter screen 16. The filter screen 16 is disposed on the return air opening 121. Specifically, the filter screen 16 may prevent dust within the controlled environment from being drawn into the return air duct 12. Filter 16 is removable for periodic cleaning.

Specifically, the fans of the air conditioning unit 15 may be rotated in both forward and reverse directions, and may also be configured to process the passing airflow to change the humidity and temperature of the airflow. In the cooling mode, the fan of the air conditioning box 15 rotates forward to generate negative pressure in the return air duct 12, and air in the controlled environment enters the return air duct along the return air inlet 121 and is processed by the air conditioning box 15, and is blown to the controlled environment through the air supply outlet. In the dust removal mode, the blower of the air conditioning box 15 is reversed, so that negative pressure is generated in the air supply pipeline 11, air enters the air supply pipeline 11 through the air supply port and then reversely flows through the dust discharge port 122 in the return air pipeline 12 to be blown out, and dust and impurities adsorbed on the inner wall of the return air pipeline 12 are removed, so that peculiar smell is reduced. In addition, the baffle 14 automatically covers the air return opening 121 in the dust removing mode, so that dust is prevented from passing through the air return opening 121 and polluting the filter screen 16 on the air return opening 121.

In some embodiments, as shown in fig. 11, in the dust removal mode, the baffle 14 is rotated toward the return air inlet 121 side by the reverse airflow. In the dust removal mode, the fan of the air conditioning box 15 is reversed, the baffle 14 automatically covers the air return opening 121 under the action of air flow, the baffle 14 does not need to be manually controlled to rotate, and the operation is simple and convenient. The baffle 14 is made of a lightweight material that is corrosion resistant and has a structural strength and rigidity to facilitate frequent rotation and increase service life.

Referring to fig. 5, in some embodiments, the air conditioning module 1 further includes a spring 13. One end of the baffle 14 is rotatably connected with the inner wall of the return air duct 12, and the other end of the baffle 14 is connected with the inner wall of the return air duct 12 through a spring 13. In the cooling mode, the baffle 14 covers the dust discharge opening 122 by the elastic force of the spring 13.

To increase the tightness of the baffle 14 against the return air inlet 121 and the dust exhaust 122 and to make the air flow more prone to force the baffle 14, in some embodiments, the baffle 14 includes a protrusion. In the cooling mode, the shutter 14 covers the dust discharge port 122 and the protrusion is caught in the dust discharge port 122 by the elastic force of the spring 13. In the dust removal mode, the reverse air flow makes the baffle plate 14 overcome the elastic force of the spring 13 and rotate to the other side to cover the air return opening 121, and the protruding part covers the outer side of the air return opening. Referring specifically to fig. 4, since the baffle 14 has a convex portion, the baffle 14 is shown in front view as being convex on one side and concave on the other side. That is, a portion of the baffle 14 is curved. When the air conditioning case 15 rotates forward, as shown in fig. 8, the protruding portion of the baffle 14 is sunk into the dust discharge opening 122, and the airflow flowing forward generates a force on the concave surface of the baffle 14, and the force component of the force vertically downward matches with the elastic force of the spring 13, so that the baffle 14 is further pressed against the dust discharge opening 122, and the shielding effect of the baffle 14 on the dust discharge opening 122 is increased. When the air conditioning case 15 is reversed, the reversed air flow first acts on the convex surface of the baffle 14 which is not caught in the dust discharge port 122 to rotate the baffle 14 against the force of the spring 13 to the state shown in fig. 11, and then the reversed air flow continues to exert a force on the convex surface of the baffle 14 to keep the return air port 121 covered tightly. When the air conditioning box 15 stops reversing, the baffle 14 is reset to the state shown in fig. 8 under the action of the spring 13, the whole process is automatic, the covering of the return air inlet 121 and the dust discharge port 122 can be well realized, the return air inlet 121 is prevented from being polluted by dust in the pipeline, and the phenomenon that the air conditioning module 1 is in a refrigerating mode can be avoided, and the residual dust in the dust discharge port 122 is re-inhaled by the negative pressure in the return air pipeline 12. Further, the dust exhaust port 122 is well sealed, so that the air tightness in the return air duct 12 can be improved, and the air suction capability of the return air port 121 is improved, so that the space air flow is prevented from entering the return air duct 12 from the dust exhaust port 122.

Referring to fig. 2 and 3, in some embodiments, the baffle 14 includes a cover plate 141 and a rim 142. The rim 142 is disposed around the cover plate 141. The rim 142 is made of a hard material. The cover plate 141 is made of a soft material. Specifically, the use of a hard material (e.g., aluminum alloy) for the rim 142 may increase the overall structural strength of the baffle 14 and increase the service life. The cover plate 141 may be in close contact with the return air inlet 121 and the dust exhaust port 122 using a soft material (e.g., rubber) to improve a covering performance.

In some embodiments, the baffle 14 further comprises a gasket. A gasket is provided on the rim 142 to further increase the covering performance of the baffle 14.

The air conditioning module 1 includes a plurality of baffles 14. The baffles 14 are correspondingly arranged between the air return openings 121 and the dust exhaust openings 122. The number of the return air inlets 121 and the dust exhaust outlets 122 is set to be plural, so that the air supply efficiency and the dust removal effect can be improved.

In some embodiments, the air conditioning module 1 further comprises a wind meter. The wind meter is used for detecting the wind speed in the return air duct 12. Further, the air conditioning module 1 further comprises a controller in signal connection with the air meter and the air conditioning case 15. The controller controls the rotational speed of the air conditioning box 15 based on the wind speed data detected by the wind meter to ensure that the wind speed in the return air pipeline 12 can meet the force of overcoming the spring 13 and drive the baffle 14 to rotate. The controller is also able to prevent blowing out the pipe wall by controlling the rotational speed of the air conditioning tank 15 to bring the wind speed below a set point.

Referring to fig. 13, the present application also provides an air conditioning system including at least three air conditioning modules 1, a return air parallel passage 2, and an air supply parallel passage 3 as described above.

The air supply parallel passage 3 is used to connect the air supply ducts 11 of the three air conditioning modules 1. The return air parallel passage 2 and the air supply parallel passage 3 are both provided on-off. By means of the air conditioning system, air in a plurality of controlled environments can be purified, and the temperature and humidity of the air in the plurality of controlled environments can be regulated. Further, the air conditioning modules 1 can suck the air in the controlled environment corresponding to each other and then blow the air into the dust exhaust port 122 of one air conditioning module 1 through the return air parallel passage 2, so as to realize larger air quantity in the single return air pipeline 12 and improve the dust removal effect on one return air pipeline 12.

With continued reference to fig. 13, in some embodiments, the air conditioning system further includes a communication main 4. The communicating main pipe 4 is connected with the return air parallel passage 2 and the air supply parallel passage 3. The communication main pipe 4 is provided on-off.

The pressure difference meter can enable workers to know the air pressure in the pipeline in real time, so that the safety and reliability of the whole air conditioning system are higher.

In some embodiments, the air conditioning system further comprises a controller. The controller is connected with the pressure detection device in a signal way and is used for controlling the on-off of the on-off valves 5, the working modes of the air conditioning modules 1 and the closing and opening of the pressure relief ports 17. Specifically, the pressure relief opening 17 may be an electric control valve, where the valve core opening of the electric control valve is controlled by a signal of the controller, and when the pressure in the return air duct 12 is too high, the controller sends a signal to make the valve core opening of the electric control valve become large so as to implement pressure relief.
