At this time, multiple air supply groups respectively supply air to different height areas in the workshop, and the air in different height areas in the workshop respectively returns through multiple return air groups, so as to form multiple circulating air flows at different heights in the workshop, which not only avoids the formation of eddy currents and air flow swirls in the working area, but also avoids the pollution of the lower-layer clean working area caused by the downward pressure of the upper-layer air, and ensures the air cleanliness at each working height in the workshop.

[0047] Next, the technical solutions shown in the present application will be described in detail through specific embodiments.

The workshop includes at least one working space, and the working space includes two opposite side walls 100. The air treatment system includes: an air supply group 200, a return air group 300 and an air treatment unit 400.

[0049] The air supply group 200 and the air return group 300 are both arranged inside the side wall 100. The air supply group 200 and the air return group 300 are both multiple ones spaced apart along the height direction of the side wall 100.

The air supply openings 210 on the two side walls 100 are arranged oppositely, and the air return openings 310 on the two side walls 100 are arranged oppositely.

[0050] The air handling unit 400 includes: a casing 410, a fan 420 and a heat exchange component 430. Among them, the casing 410 defines a body flow channel, and the body flow channel is communicated with the air supply openings 210 and the air return openings 310 of the two side walls 100 respectively; the fan 420 is arranged in the body flow channel to drive the air flow to flow in the body flow channel; the heat exchange component 430 is arranged in the body flow channel to exchange heat with the air flow flowing through the body flow channel.

[0051] Exemplarily, the workshop includes two working spaces. The two working spaces share three side walls 100, where one side wall 100 is in the middle and the other two side walls 100 are on both sides to form two working spaces.

[0052] Exemplarily, both the air supply group 200 and the air return group 300 are spaced apart in three along the height direction of the side wall 100.

[0053] Exemplarily, a plurality of air handling units 400 are provided, and each air handling unit 400 is used to provide air volume to a plurality of air supply groups 200 and air return groups 300. The number of air handling units 400 is related to the size of the workshop and the total air volume required by the workshop.

[0054] Exemplarily, referring to Figure 4 , the casing 410 includes a fresh air section, a primary filter section, a pre-cooling / pre-heating section, a return air section, a medium filter section, a surface cooling / heating section, a humidifying section, a supply air fan 420 section, a uniform flow section, a high-efficiency filter section and an air outlet section that are connected in sequence. The heat exchange component 430 includes a primary filter element, a pre-cooling / pre-heating element, a medium filter element, a surface cooling / heating element, a humidifier, a fan 420 and a high-efficiency filter element. Among them, the primary filter element is arranged in the primary filter section, the pre-cooling / pre-heating element is arranged in the pre-cooling / pre-heating section, the medium filter element is arranged in the medium filter section, the surface cooling / heating element is arranged in the surface cooling / heating section, the humidifier is arranged in the humidifying section, the fan 420 is arranged in the supply air fan 420 section, and the high-efficiency filter element is arranged in the high-efficiency filter section. The air outlet section is communicated with the air supply group 200, and the return air section is communicated with the air return group 300.

[0055] By adopting the above technical solution, when air treatment is required in the factory, the air handling unit 400 supplies air to the air supply port 210. At this time, multiple air supply groups 200 supply air to different height areas in the factory respectively. The air in different height areas in the factory is returned through multiple return air groups 300 respectively, so that the factory forms multiple circulating air flows at different heights, which not only avoids the formation of vortices and air swirls in the working area, but also avoids the pollution of the clean working area below caused by the downward pressure of the upper air, thereby ensuring the air cleanliness at each working height in the factory.

[0056] In some embodiments provided in this application, for example, reference Figure 2 and Figure 3 The air supply outlets 210 of the plurality of air supply groups 200 correspond one to one along the height direction of the side wall 100 .

[0057] Exemplarily, the air supply outlets 210 in the three air supply groups 200 are respectively 4 meters, 9 meters and 14 meters away from the ground.

[0058] By adopting the above technical solution, the two air supply outlets 210 arranged relatively to each other can blow towards each other, thereby ensuring that there is sufficient fresh air in the factory building in different height areas.

[0059] In some embodiments provided in the present application, illustratively, the return air outlets 310 of the plurality of return air groups 300 correspond one to one along the height direction of the side wall 100 .

[0060] Exemplarily, the three return air groups 300 are respectively 1 meter, 7 meters and 11 meters from the ground.

[0061] By adopting the above technical solution, the return air volume in different height areas of the factory is guaranteed, thereby ensuring the air cleanliness at each working height in the factory.

[0062] In some embodiments provided in the present application, illustratively, each side wall 100 is provided with a plurality of ventilation areas distributed along the height direction of the side wall 100 .

[0063] At least one air supply group 200 and at least one return air group 300 are provided in each ventilation area. In each ventilation area, the height of the air supply group 200 is located at the height of the return air group 300.

[0064] Exemplarily, three ventilation zones are provided, each of which is provided with an air supply group 200 and a return air group 300 .

[0065] By adopting the above technical solution, the side wall 100 is divided into several ventilation areas, and at least one supply air group 200 and at least one return air group 300 are arranged in each ventilation area. The factory building can be divided into multiple different circulation layers along the height direction, and each circulation layer can circulate air, thereby preventing the polluted air and uneven temperature and humidity air in the upper layer of the factory building from falling into the clean working area below, thereby affecting the clean working area below.

[0066] Moreover, the air supply group 200 and the return air group 300 have multiple air supply outlets 210 and return air outlets 310 in the length direction of the factory, which can also avoid the interference of tall equipment in the factory on the air flow movement to the greatest extent possible, thereby ensuring that each circulation layer can have stable air flow movement.

[0067] In some embodiments provided in this application, for example, reference Figure 2 and Figure 3 The air supply port 210 and the air return port 310 disposed on the same side wall 100 are staggered along the length direction and / or the height direction of the side wall 100 .

[0068] Exemplarily, the air supply outlet 210 and the air return outlet 310 located in the same ventilation area differ by 1-2 meters in the height direction and by 2-3 meters in the length direction.

[0069] By adopting the above technical scheme, after the air supply outlet 210 conveys the fresh air into the factory, the fresh air flows in a direction parallel to the air supply outlet 210, and the air supply outlet 210 outputs the air in the factory in a direction parallel to the air supply outlet 210. At this time, the fresh air can enter the area parallel to the air supply outlet 210, so that the fresh air circulates in the local area in the height direction between the air supply outlet 210 and the return air outlet 310, and is staggered in the length direction, so that the fresh air circulates in the local area in the length direction between the air supply outlet 210 and the return air outlet 310, which shows the effect of the air treatment system on the air circulation in the factory.

[0070] In some embodiments provided in this application, for example, reference Figure 2 An air supply channel 110 and an air return channel 120 are also provided in the side wall 100. The air supply channel 110 is connected to the air supply port 210 and the outlet of the machine body flow channel respectively, and the return air channel 120 is connected to the return air port 310 and the inlet of the machine body flow channel respectively.

[0071] Exemplarily, the air supply passages 110 and the air return passages 120 are arranged along the height direction of the factory building, and adjacent air supply passages 110 and air return passages 120 are arranged in a staggered manner.

[0072] The above technical solution is usually adopted to facilitate the connection between the air supply port 210, the air return port 310 and the body flow channel by providing the air supply channel 110 and the air return channel 120.

[0073] In some embodiments provided by the present application, by way of example, the side wall 100 includes metal plates, and there are two metal plates arranged opposite to each other and spaced apart.

[0074] Both the air supply opening 210 and the air return opening 310 are formed in the metal plates.

[0075] Exemplarily, the metal plates are color steel plates, and the two color steel plates are fixed in parallel and spaced apart in the factory building to form the side wall 100.

[0076] By adopting the above technical solution, the two metal plates are arranged opposite to each other and spaced apart to form the side wall 100, reducing the production and manufacturing cost of the side wall 100, and arranging the air supply opening 210 and the air return opening 310 on the metal plates, reducing the cost of arranging the air supply opening 210 and the air return opening 310.

[0077] In some embodiments provided by the present application, by way of example, the side wall 100 further includes a plurality of columns, and the plurality of columns are arranged side by side between the two metal plates along the length direction of the side wall 100.

[0078] The plurality of columns include air return columns and air supply columns. The air return columns define an air return channel 120 communicating with the air return opening 310, and the air supply columns define an air supply channel 110 communicating with the air supply opening 210.

[0079] Exemplarily, the columns are square color steel plate columns.

[0080] By adopting the above technical solution, by arranging the air return columns and the air supply columns, with the air return columns serving as the air return channel 120 and the air supply columns serving as the air supply channel 110, it is convenient to connect the air handling unit 400 with the air supply opening 210 and the air return opening 310.

[0082] By adopting the above technical solution, by arranging double-sided louvers at the air supply opening 210, the air supply range and the air supply area of the air supply opening 210 can be adjusted; by arranging single-sided louvers at the air return opening 310, it is convenient to clean and maintain the air return opening 310.

[0083] In some embodiments provided by the present application, by way of example, it further includes: a filtering member, and the filtering member is arranged at the air return opening 310.

[0084] Exemplarily, the filtering member is a filter net, and the filter net is detachably installed at the air return opening 310.

[0085] By adopting the above technical solution, by providing a filter element on the air return opening 310, the air entering the air return opening 310 can be preliminarily filtered to ensure the quality of the return air.
