Description

Technical Field

[0001] The utility model relates to the technical field of air processing and supply, in particular to a multi-airflow guide module and an air processing device. Background Art

[0002] In the field of modern air handling devices, in order to improve energy efficiency and indoor air quality, heat exchange units such as full heat exchangers are often used to achieve heat exchange between fresh air and return air, and the return air after heat exchange forms exhaust air. For example, the working principle of the full heat exchanger is to transfer the heat (or cold) in the return air to the fresh air through special heat exchange materials, thereby reducing the energy consumption required for fresh air processing.

[0003] While this heat exchange method brings energy-saving advantages, it also causes a series of problems. Among them, the most notable is the increase in the volume of the entire air handling device. Since the heat exchange unit itself requires a large heat exchange area and a complex internal structure to achieve efficient heat exchange, and it is necessary to set up multiple appropriate flow channels to achieve the transportation of fresh air, exhaust air, return air and supply air, this will inevitably increase the space occupied by the air handling device. For example, in some small commercial places or residences, due to limited space, an overly large air handling device may cause great difficulties in installation and layout. In addition, the larger volume also increases the transportation and maintenance costs of the device.

[0004] In summary, although the heat exchange between fresh air and exhaust air through the heat exchange unit has significant advantages in energy saving, the resulting large size of the air handling device has become an important factor restricting its wider application and development.

[0099] In order to solve the problem of large volume while achieving heat exchange between fresh air and exhaust air through a heat exchange unit, a multi-airflow guide module is proposed in this application. Figure 1 This is a schematic structural diagram of a multi-airflow guide module in a first embodiment of the utility model. Figure 2 This is a schematic structural diagram of the multi-airflow guide module in the embodiment of the utility model at another angle in the first embodiment. Figure 3 This is a front view of the multi-airflow guide module in the first embodiment of the utility model (part of the housing is not shown), Figure 4 This is a rear view of the multi-airflow guide module in the first embodiment of the utility model (part of the housing is not shown). Figure 5 This is a schematic structural diagram of the multi-airflow guide module in the second embodiment of the utility model. Figure 6 This is a schematic structural diagram of the multi-airflow guide module in the second embodiment of the utility model at another angle. Figure 7 This is a front view of the multi-airflow guide module in the second embodiment of the utility model (part of the housing is not shown), Figure 8 FIG. 1 is a right side view of the multi-airflow guide module in the second embodiment of the utility model (part of the housing is not shown), as shown in FIG. Figures 1 to 8 As shown, the multi-airflow guide module may include: a shell 2, the shell 2 having a first port 21, a second port 22, and a third port 23; a first heat exchange unit 1 and a first partition component 3 arranged in the shell 2, the first partition component 3 and the first heat exchange unit 1 separate the shell 2 into a first channel 24, a second channel 25, and a third channel 26 that are connected to the first port 21, the second port 22, and the third port 23 in a one-to-one correspondence; the first channel 24 and the second channel 25 are distributed along the first direction, at least a portion of the first channel 24, at least a portion of the second channel 25, and at least a portion of the first heat exchange unit 1 are located in the same plane in the second direction, the third channel 26 is distributed in the second direction as the first channel 24, the second channel 25, and the first heat exchange unit 1 that are located in the same plane, and the first channel 24 and the second channel 25 are closely arranged in the first direction.

[0100] The multi-airflow guiding module in the present application can use the first channel 24, the second channel 25 and the third channel 26 as the fresh air channel, the return air channel and the exhaust air channel as needed, and can satisfy the heat exchange between the air input to the first heat exchange unit 1 from the fresh air channel and the air input to the first heat exchange unit 1 from the return air channel, and the air input to the first heat exchange unit 1 from the return air channel can be discharged through the exhaust air channel after being discharged from the first heat exchange unit 1. Since at least part of the first channel 24, at least part of the second channel 25 and at least part of the first heat exchange unit 1 are located in the same plane in the second direction, and the third channel 26 is distributed along the second direction with the first channel 24, the second channel 25 and the first heat exchange unit 1 located in the same plane, the space of the multi-airflow guiding module in the second direction can be fully utilized, and since the first channel 24 and the second channel 25 are distributed along the first direction, and the first channel 24 and the second channel 25 are arranged close to each other in the first direction, the distance between the multi-airflow guiding modules in the first direction can be shortened. Combining the above two advantages, the layout of the entire multi-airflow guide module can be made more reasonable and the interior more compact, thereby reducing the volume of the entire multi-airflow guide module to a certain extent, making it easier for the multi-airflow guide module to be installed or arranged in more air treatment devices with miniaturization requirements.

[0101] In order to better understand the multi-airflow guide module in this application, it will be further explained and illustrated below. Figures 1 to 8 As shown, the shell 2 can be hollow, and its interior can be used to set components such as the first heat exchange unit 1 and the first partition assembly 3, so that a plurality of channels with different functions can be formed in the shell 2. The shell 2 can have a first port 21, a second port 22, and a third port 23. The first port 21, the second port 22, and the third port 23 can be used as a fresh air inlet, a return air inlet, and an exhaust outlet. It should be emphasized that the first port 21 is not necessarily used as a fresh air inlet, and it can be used as any one of the fresh air inlet, the return air inlet, and the exhaust outlet, and the same applies to other ports. The first port 21, the second port 22, and the third port 23 can be located at any position on the shell 2, and they are not limited in this application.

[0102] As preferably, Figures 1 to 8 As shown, the first port 21, the second port 22 and the third port 23 are located at the upper part of the housing 2. Here, the upper part of the housing 2 can be the top wall of the housing 2, or the upper part of the side wall of the housing 2. In this way, the air ducts corresponding to the first port 21, the second port 22 and the third port 23 can be connected to the upper part of the housing 2, which is helpful for laying the air ducts in the building. For example, the air ducts can be directly extended upward into the ceiling of the house. After the entire multi-airflow guide module is connected to the air duct, the whole is both beautiful and simple.

[0103] like Figures 1 to 8As shown, the first heat exchange unit 1 and the first partition assembly 3 are arranged in the housing 2. The first heat exchange unit 1 has a first heat exchange channel 11 and a second heat exchange channel 12, and the gas flowing through the first heat exchange channel 11 can exchange heat with the gas flowing through the second heat exchange channel 12. Specifically, the fresh air needs to enter one heat exchange channel of the first heat exchange unit 1, and at least part of the return air needs to enter another heat exchange channel of the first heat exchange unit 1. The two exchange heat through the first heat exchange unit 1, and the return air after heat exchange becomes exhaust air, which is subsequently discharged from the exhaust port after passing through the corresponding channel.

[0104] The first partition assembly 3 and the first heat exchange unit 1 separate the shell 2 into a first channel 24, a second channel 25 and a third channel 26 which are connected to the first port 21, the second port 22 and the third port 23 in a one-to-one correspondence. The first channel 24, the second channel 25 and the third channel 26 are used as fresh air channels, return air channels and exhaust channels as needed. It should be emphasized that the first channel 24 is not necessarily used as a fresh air channel, it can be used as any one of the fresh air channels, return air channels and exhaust channels, and the same applies to other channels. The first channel 24 and the second channel 25 correspondingly connected to two adjacent ports of the first heat exchange channel 11 and the second heat exchange channel 12 extend from the two ports in the same direction respectively.

[0105] The first channel 24 and the second channel 25 are distributed along the first direction. The first channel 24 and the second channel 25 can be arranged close to each other in the first direction. At least part of the first channel 24, at least part of the second channel 25 and at least part of the first heat exchange unit 1 are located in the same plane in the second direction. In the second direction, the third channel 26 can correspond to the first channel 24, the second channel 25 and the first heat exchange unit 1. In this way, the distance between the multi-airflow guide modules in the first direction can be reduced. As feasible, the corresponding areas of the first channel 24, the second channel 25 and the first heat exchange unit 1 in the second direction can form the third channel 26 in whole or in part, and the third channel 26 is within the size range of the first channel 24 and the second channel 25 in the first direction, so that the distance between the multi-airflow guide modules in the first direction can be reduced as much as possible.

[0106] As a feasible method, most or all of the first channel 24, the second channel 25 and the first heat exchange unit 1 are located in the same plane in the second direction. As a feasible method, the distances between the first channel 24, the second channel 25 and the first heat exchange unit 1 in the second direction can be substantially equal. The third channel 26 is distributed along the second direction with the first channel 24, the second channel 25 and the first heat exchange unit 1 located in the same plane. In this way, the space of the multi-airflow guide module in the second direction can be fully utilized to form the third channel 26.

[0107] The above structure can make the layout of the entire multi-airflow guide module more reasonable and the interior more compact, thereby reducing the volume of the entire multi-airflow guide module to a certain extent, making it easier for the multi-airflow guide module to be installed or arranged in more air treatment devices with miniaturization requirements.

[0108] In one embodiment, the first direction may be a left-right width direction, and the second direction may be a front-back thickness direction. In another embodiment, the first direction may be a front-back thickness direction, and the second direction may be a left-right width direction.

[0109] When the inlet and outlet of the first heat exchange channel 11 are arranged oppositely, the inlet and outlet of the second heat exchange channel 12 are arranged oppositely, and the inlet and outlet of the first heat exchange channel 11 and the second heat exchange channel 12 are cross-distributed, the first channel 24 and the second channel 25 corresponding to the two adjacent ports of the first heat exchange channel 11 and the second heat exchange channel 12 can extend upward from the two ports respectively. In this way, the first channel 24 and the second channel 25 can be closely arranged in the first direction and share part of the first partition component 3. In this way, only the parallel first channel 24 and the second channel 25 can exist above the first heat exchange unit 1, and the distance between the multi-airflow guide modules in the first direction can be reduced as much as possible.

[0110] In a first embodiment, if Figures 1 to 4 As shown, the first channel 24 is a fresh air channel, and the second channel 25 is an exhaust air channel. In this embodiment, the fresh air channel is connected to the inlet of the first heat exchange channel 11, and the exhaust air channel is connected to the outlet of the second heat exchange channel 12. The inlet of the first heat exchange channel 11 and the outlet of the second heat exchange channel 12 are generally facing upward or obliquely upward. The third channel 26 is a return air channel, and the return air channel is connected to the outlet of the first heat exchange channel 11 and the inlet of the second heat exchange channel 12. The third channel 26 and the lower area of ​​the first heat exchange unit 1 form an air supply channel, and the return air passing through the return air channel and the fresh air flowing out of the outlet of the first heat exchange channel 11 are combined to form supply air together in the air supply channel.

[0111] The third area 29 is located below the fresh air channel. In the first heat exchange unit 1 , another inlet adjacent to the inlet of the first heat exchange channel 11 is located in the third area 29 .

[0112] In this embodiment, the first partition assembly 3 includes a first partition 31 and a second partition 32. The first partition 31 and the first heat exchange unit 1 separate the first area 27 and the second area 28 distributed along the second direction in the shell 2. The first area 27 is formed between the first partition 31 and the shell 2, and the first partition 31, the first heat exchange unit 1 and the shell 2 form the second area 28. The return air channel is located in the first area 27.

[0113] The second partition 32 divides the second area 28 into a second area first sub-area 281 and a second area second sub-area 282 distributed along the first direction, the fresh air channel is located in the second area first sub-area 281, and the exhaust air channel is located in the second area second sub-area 282. The two ends of the first heat exchange unit 1 in the first direction are respectively sealed and connected to the shell 2, so that the inlet of the first heat exchange channel 11 and the inlet of the second heat exchange channel 12 are separated, and the outlet of the first heat exchange channel 11 and the outlet of the second heat exchange channel 12 are separated.

[0114] As a feasible method, a bypass port 36 connecting the first port 21 and the first area 27 is provided on the first partition 31 corresponding to the first sub-area 281 of the second area. When the fresh air input from the fresh air port into the fresh air channel does not need to pass through the first heat exchange unit 1, the fresh air can directly enter the return air channel through the bypass port 36, thereby mixing with the return air and then forming the supply air together. For example, when the user only needs to ventilate the room, the temperature of the fresh air is close to the temperature of the room, and at this time, the fresh air does not need to exchange heat with the return air.

[0115] A third area 29 connected to the inlet of the second heat exchange channel 12 is formed between the first heat exchange unit 1, the first partition assembly 3 and the shell 2. The third area 29 has a first connection 312 with the return air channel. The return air channel has a second connection with the outlet of the first heat exchange channel 11. On the return air channel, the first connection 312 is located upstream of the second connection. Through the above, at least part of the return air in the return air channel can preferentially enter the third area 29 through the first connection 312, and then enter the second heat exchange channel 12 and be discharged from the exhaust channel, and the remaining return air in the return air channel continues to flow downstream and mixes with the fresh air flowing out of the outlet of the first heat exchange channel 11 to form supply air, and the supply air continues to flow downstream. In this way, it is possible to avoid the fresh air flowing out of the outlet of the first heat exchange channel 11 from flowing into the first connection 312, and then entering the second heat exchange channel 12 and being discharged from the exhaust channel, thereby avoiding the waste of fresh air.

[0116] In order to form the third region 29, as a feasible method, the first partition component 3 may include: a fourth partition 34 and a fifth partition 35 connected at one end to both sides of the inlet of the second heat exchange channel 12, and the other ends of the fourth partition 34 and the fifth partition 35 are connected to the shell 2, so that the third region 29 is formed between the fourth partition 34, the fifth partition 35, the shell 2, the first partition 31 and the first heat exchange unit 1. The third region 29 is separated from the first sub-region 281 of the second region by the fourth partition 34. In the second direction, the two ends of the fourth partition 34 are sealed with the shell 2 and the first partition 31, respectively. In the second direction, the two ends of the fifth partition 35 are sealed with the shell 2 and the first partition 31, respectively. Similarly, in the second direction, the two sides of the first heat exchange unit 1 are sealed with the shell 2 and the first partition 31, respectively. The third region 29 is separated from the air supply channel below by the fifth partition 35. The first connection 312 is located at the end of the third region 29 in the second direction. That is, in the second direction, a first connecting portion 312 is formed on a side of the third region 29 facing the first region 27 .

[0117] In a second embodiment, if Figures 5 to 8 As shown, the first channel 24 is a fresh air channel, and the second channel 25 is a return air channel. The fresh air channel is connected to the inlet of the first heat exchange channel 11, and the return air channel is connected to the outlet of the first heat exchange channel 11 and the inlet of the second heat exchange channel 12. The inlet of the first heat exchange channel 11 and the inlet of the second heat exchange channel 12 are generally facing upward or obliquely upward. The third channel 26 is an exhaust air channel, and the exhaust air channel is connected to the outlet of the second heat exchange channel 12. The area below the outlet of the first heat exchange channel 11 of the first heat exchange unit 1 and below the second channel 25 forms an air supply channel. At least part of the return air passing through the return air channel can flow into the inlet of the second heat exchange channel 12, and then be discharged through the third channel 26; the remaining return air passing through the return air channel can be combined with the fresh air flowing out of the outlet of the first heat exchange channel 11 to form supply air in the air supply channel.

[0118] The third area 29 is located below the fresh air channel. In the first heat exchange unit 1 , another inlet adjacent to the inlet of the first heat exchange channel 11 is located in the third area 29 .

[0119] In the return air channel, the connection point between the return air channel and the inlet of the second heat exchange channel 12 is located upstream of the connection point between the return air channel and the outlet of the first heat exchange channel 11 .

[0120] In this embodiment, the first partition assembly 3 includes a first partition 31 and a second partition 32. The first partition 31 and the first heat exchange unit 1 separate the housing 2 into a first area 27 and a second area 28 distributed along the second direction, and the exhaust passage is located in the first area 27.

[0121] The second partition 32 separates the second area 28 into the first sub-area 281 of the second area and the second sub-area 282 of the second area distributed along the first direction. The lower end of the second partition 32 is sealed and connected to the first heat exchange unit 1, and the connection is located between the two openings of the first heat exchange channel 11 and the second heat exchange channel 12; the upper end of the second partition 32 is sealed and connected to the shell 2. In the second direction, the two sides of the second partition 32 are sealed and connected to the shell 2 and the first partition 31 respectively. The fresh air channel is located in the first sub-area 281 of the second area, and the return air channel is located in the second sub-area 282 of the second area. One end of the first heat exchange unit 1 in the first direction is sealed and connected to the shell 2, so that the inlet of the first heat exchange channel 11 and the outlet of the second heat exchange channel 12 are separated. A third area 29 connected to the outlet of the second heat exchange channel 12 is formed between the first heat exchange unit 1, the first partition assembly 3 and the shell 2, and the third area 29 is connected to the first area 27, and the first area 27 is separated from the return air channel.

[0122] Specifically, the first partition assembly 3 may include: a fourth partition 34 and a fifth partition 35 connected at one end to both sides of the outlet of the second heat exchange flow channel 12. The other ends of the fourth partition 34 and the fifth partition 35 are connected to the shell 2, so that a third area 29 is formed between the fourth partition 34, the fifth partition 35, the shell 2, the first partition 31 and the first heat exchange unit 1. The third area 29 is separated from the first sub-area 281 of the second area by the fourth partition 34. In the second direction, the two ends of the fourth partition 34 are sealed with the shell 2 and the first partition 31, respectively. In the second direction, the two ends of the fifth partition 35 are sealed with the first partition 31 and the shell 2, or the two ends of the fifth partition 35 are sealed with the shell 2. Similarly, in the second direction, the two sides of the first heat exchange unit 1 are sealed with the shell 2 and the first partition 31, respectively. The third area 29 is separated from the air supply channel below by the fifth partition 35.

[0123] As a feasible method, a bypass port 36 connecting the fresh air channel and the return air channel is provided on the second partition 32 .

[0124] In the above two embodiments, Figures 1 to 8 As shown, when the first partition component 3 has a bypass port 36 connecting the fresh air channel and the return air channel, as feasible, the multi-airflow guide module may include: a switching component 4. The switching component 4 can control the connection and disconnection between the first port 21 and the return air channel through the bypass port 36, and / or the connection and disconnection between the first port 21 and the inlet of the first heat exchange flow channel 11.

[0125] Through the above structure, further, the multi-airflow guide module may include a first working state and a second working state. In the first working state, the switching component 4 controls the first port 21 to be connected to the inlet of the first heat exchange channel 11, and the first port 21 is disconnected from the return air channel through the bypass port 36. In the second working state, the switching component 4 controls the first port 21 to be disconnected from the inlet of the first heat exchange channel 11, and the first port 21 is connected to the return air channel through the bypass port 36. Through the first working state, the fresh air can be controlled to enter the first heat exchange channel 11 of the first heat exchange unit 1 to exchange heat with the return air, and the part of the return air that has undergone heat exchange forms exhaust air. Through the second working state, the fresh air can be controlled to enter the return air channel directly without passing through the first heat exchange unit 1.

[0126] Furthermore, the multi-airflow guiding module may include a third working state and a fourth working state. In the third working state, the switching component 4 controls the first port 21 to be connected to the inlet of the first heat exchange channel 11, and the first port 21 is connected to the return air channel through the bypass port 36. In the fourth working state, the switching component 4 controls the first port 21 to be disconnected from the inlet of the first heat exchange channel 11, and the first port 21 is disconnected from the return air channel through the bypass port 36. Through the third working state, part of the fresh air can be controlled to enter the first heat exchange channel 11 of the first heat exchange unit 1 to exchange heat with the exhaust air, and part of the fresh air directly enters the return air channel without passing through the first heat exchange unit 1. Through the fourth working state, the multi-airflow guiding module can be controlled so that no fresh air enters the return air channel, that is, the indoor room does not need to be replenished with fresh air.

[0127] In the above two embodiments, at least part of the side wall forming the fresh air channel is shared with part of the side wall forming the return air channel, and the bypass port 36 is provided on the shared side wall. This can make the entire multi-airflow guide module more compact and smaller in size, and no additional connecting channel is required to connect the fresh air channel with the return air channel.

[0128] In a specific embodiment, Figures 1 to 8 As shown, the switching component 4 may include a first air valve 41 and a second air valve 42 disposed at the bypass port 36. The first air valve 41 is disposed in the fresh air channel and can control the opening and closing of the first port 21 and the inlet of the first heat exchange flow channel 11. Of course, in other feasible embodiments, the switching component 4 may adopt other forms or structures, which are not limited in the present application.

[0129] Specifically, if Figures 1 to 8As shown, the first partition assembly 3 may include: a third partition 33 that divides the fresh air channel into a shunt space 2811 and a connecting space 2812. The third partition 33 may have a main port 331, and a first air valve 41 is installed at the main port 331. The first port 21 communicates with the main port 331 and the bypass port 36 through the shunt space 2811. The connecting space 2812 communicates with the main port 331 and the inlet of the first heat exchange flow channel 11.

[0130] In the above two embodiments, the multi-air flow guide module can have the following mode, the fresh air flowing into the fresh air channel from the fresh air inlet can enter the inlet of the first heat exchange channel 11 through the first air valve 41, and exchange heat with the return air entering the second heat exchange channel 12, and then only the fresh air forms the supply air in the supply air channel, and the return air all enters the second heat exchange channel 12 to form exhaust air.

[0131] In another embodiment, the multi-air flow guiding module may have the following mode, the fresh air flowing into the fresh air channel from the fresh air inlet may enter the second air valve 42 opened at the bypass port 36 to enter the return air channel, and then enter the supply air channel, after which only the fresh air forms supply air in the supply air channel, and the multi-air flow guiding module may not have return air input; when the multi-air flow guiding module has return air input, all the return air may enter the second heat exchange channel 12 and then be discharged from the exhaust air channel.

[0132] In another embodiment, the multi-air flow guide module may have the following mode: there is no fresh air input to the multi-air flow guide module. At this time, the second air valve 42 at the bypass port 36 is closed, and the first air valve 41 at the main port 331 is closed. The return air input from the return air port may all form supply air, or the return air input from the return air port may partially form supply air and partially form exhaust air after passing through the second heat exchange flow channel 12 and discharged from the exhaust air channel.

[0133] In another embodiment, the multi-airflow guide module can have the following mode. The multi-airflow guide module has a fresh air input. At this time, the second air valve 42 at the bypass port 36 is opened, and the first air valve 41 at the main port 331 is opened. The fresh air flowing into the fresh air channel from the fresh air port can enter the second air valve 42 opened at the bypass port 36 to enter the return air channel, and enter the first air valve 41 opened at the main port 331 to enter the first heat exchange channel 11 and then enter the return air channel. The two streams of fresh air converge to form supply air. At this time, the multi-airflow guide module can achieve a large amount of fresh air input. In this mode, the return air entering the return air port can at least partially pass through the second heat exchange channel 12 to form exhaust air and be discharged from the exhaust air channel. The return air entering the return air port may not form exhaust air.

[0134] In the above two implementations, as feasible, Figures 1 to 8As shown, a first filter element 5 may be provided in the fresh air channel. The first filter element 5 is used to filter the input fresh air. Furthermore, the filtering may be primary filtering to remove larger particles of impurities in the fresh air. As feasible, in the first working state, the fresh air flowing in from the first port 21 may pass through the first filter element 5 and then enter the inlet of the first heat exchange flow channel 11. As feasible, in the second working state, the fresh air flowing in from the first port 21 may enter the return air channel through the bypass port 36, and in this process, it may not pass through the first filter element 5. In this working state, it can be considered that the quality of the incoming fresh air is high and does not need to be filtered through the first filter element 5.

[0135] In the above two embodiments, as feasible, the multi-airflow guide module may include: an exhaust fan, the exhaust fan is used to generate suction, so that the exhaust channel draws away at least part of the return air in the return air channel to form exhaust air, and then discharges it from the exhaust port. The exhaust fan can be arranged in the exhaust channel.

[0136] The present application also proposes an air treatment device, which includes any of the above-mentioned multi-air flow guide modules. Fig. 9 FIG. 1 is a schematic diagram of the structure of the air treatment device in a feasible implementation mode in the embodiment of the utility model. Fig. 9 As shown, the housing 2 may have a fourth port 210. The fourth port 210 may serve as an air supply port, and the air passing through the air supply channel may be output from the air supply port to be supplied to a required area.

[0137] As feasible, Fig. 9 As shown, the air handling device may include an air supply fan 6 and a second heat exchange unit 7 disposed in the housing 2. The air supply fan 6 is used to generate air supply pressure, so that the return air input from the return air port and the fresh air output from the fresh air port can flow to the air supply channel and then be output from the air supply port. The second heat exchange unit 7 is used to adjust the temperature and / or humidity of the air flowing through the air supply channel. A refrigerant may flow into the second heat exchange unit 7, or other heat exchange mediums may also flow into the second heat exchange unit 7.

[0138] In the air handling device, the return air flowing in from two of the first port 21, the second port 22 and the third port 23 and the fresh air passing through the first heat exchange channel 11 are discharged from the fourth port 210 after passing through the second heat exchange unit 7 and the air supply fan 6. Optionally, at least part of the return air can be discharged from the other of the first port 21, the second port 22 and the third port 23 through the second heat exchange channel 12. Of course, in the above process, only the return air can be discharged from the fourth port 210 after passing through the second heat exchange unit 7 and the air supply fan 6; or only the fresh air can be discharged from the fourth port 210 after passing through the second heat exchange unit 7 and the air supply fan 6.

[0139] like Fig. 9 As shown, the air treatment device may include: a second partition component 8. The second partition component 8 may be disposed in the housing 2 and sealedly connected to the housing 2. The second partition component 8 extends in a vertical direction. The second partition component 8 separates the housing 2 into a first space 211 and a second space 212 distributed along a first direction. The second partition component 8 has a communication port 81 that communicates the first space 211 with the second space 212.

[0140] The first space 211, the connecting port 81, and the second space 212 form an air supply channel, one end of the air supply channel is connected to the outlet and the return air port of the first heat exchange channel 11, and the other end of the air supply channel is connected to the air supply port, and the air supply channel is U-shaped. For example, the air supply channel may include the first space 211, the connecting port 81, and the second space 212 below the outlet of the first heat exchange channel 11 of the first heat exchange unit 1.

[0141] When the second partition assembly 8 is provided in the housing 2, as shown in FIG. Fig. 9 As shown, the other ends of the fourth partition 34 and the fifth partition 35 are connected to the second partition assembly 8 so that a third area 29 is formed between the fourth partition 34 , the fifth partition 35 , the second partition assembly 8 , the first partition 31 and the first heat exchange unit 1 .

[0142] As feasible, the first port 21, the second port 22, and the third port 23 are located on the housing 2 corresponding to the first space 211. The fourth port 210, i.e., the air outlet, can be located on the housing 2 corresponding to the second space 212. The fourth port 210 can be located at the upper part of the housing 2, so that it is convenient to lay the air supply duct in the building, and the air supply duct can directly extend upward into the ceiling inside the house.

[0143] like Fig. 9 As shown, the air treatment device may include: a third heat exchange unit 9. The third heat exchange unit 9 has a third heat exchange flow channel and a fourth heat exchange flow channel. As feasible, the third heat exchange unit 9 may be arranged at the lower part of the first space 211. Fig.10 for Fig. 9 The schematic diagram of the local structure of the lower part of the first space, the lower part of the second space 212 and the connecting port 81 is as shown in FIG. Fig. 9 and Fig.10As shown, the housing 2 may have a refrigerant inlet 213 and a refrigerant outlet 214 for supplying and recovering refrigerant to the third heat exchange channel and the second heat exchange unit 7, and a heat exchange medium inlet 215 and a heat exchange medium outlet 216 for supplying and recovering heat exchange medium to the fourth heat exchange channel. The heat exchange medium input from the heat exchange medium inlet 215 flows through the fourth heat exchange channel, exchanges heat with the refrigerant input from the refrigerant inlet 213, and the heat exchange medium after heat exchange flows out from the heat exchange medium outlet 216 and is supplied to the terminal device, such as floor heating, air conditioner indoor unit, etc. through the corresponding pipeline. The refrigerant after heat exchange flows out from the refrigerant outlet 214, flows to the compressor and heat exchange unit in the outdoor unit, and then flows back into the refrigerant inlet 213.

[0144] As feasible, the refrigerant inlet 213, the refrigerant outlet 214, the heat exchange medium inlet 215 and the heat exchange medium outlet 216 can be located at the lower part of the side wall of the shell 2 or the bottom of the shell 2, so that they can be easily connected to the third heat exchange unit 9. The refrigerant inlet 213, the refrigerant outlet 214, the heat exchange medium inlet 215 and the heat exchange medium outlet 216 can also be located at the top of the shell 2, so that the pipelines connected to them outside the shell 2 can be easily extended upward into the ceiling inside the house to improve the aesthetics of the air handling device.

[0145] In order to improve the heat exchange efficiency of the third heat exchange unit 9 and reduce its volume, preferably, the third heat exchange unit 9 may adopt a plate heat exchanger.

[0146] In order to drive the heat exchange medium to flow to supply to the terminal device, as feasible, such as Fig. 9 and Fig.10 As shown, the air treatment device may include: a driving pump 101 communicated with the fourth heat exchange flow channel. In order to optimize the volume of the air treatment device, the driving pump 101 may be disposed at the lower part of the first space 211 .

[0147] In order to reduce the volume of the air treatment device, make the distance of the air treatment device in the first direction smaller, and ensure that return air, fresh air and exhaust air can easily enter and exit from the upper part of the shell 2, the first heat exchange unit 1 and the first partition assembly 3 are arranged in the upper part of the first space 211, and the air supply fan 6 is arranged in the second space 212.

[0148] As feasible, Fig. 9As shown, the air treatment device may include: a second filter element 103, and the second filter element 103 is arranged in the middle of the first space 211. Specifically, the second filter element 103 can be arranged in the middle of the first space 211 along the horizontal direction. The air in the air supply channel can continue to flow downward after being filtered by the second filter element 103. The second filter element 103 can filter both the return air and the fresh air. Furthermore, the filtering accuracy of the second filter element 103 can be higher than the filtering accuracy of the first filter element 5. The second filter element 103 can be installed in the middle of the first space 211 in an insertable manner. The second filter element 103 can be inserted into the first space 211 in the shell 2 along the second direction, and can also be pulled out from the first space 211 in the shell 2 along the second direction, so that the second filter element 103 can be easily replaced.

[0149] As feasible, Fig. 9 and Fig.10 As shown, the second heat exchange unit 7 can be arranged at the connecting port 81. The air in the air supply channel can exchange heat with the second heat exchange unit 7 when flowing through the connecting port 81. The second heat exchange unit 7 can be arranged in the vertical direction, basically covering the entire connecting port 81, so that the air flowing through the connecting port 81 can be fully heat exchanged. The second heat exchange unit 7 can adopt a structural form of a heat exchange tube with fins to improve the heat exchange efficiency. Furthermore, since the lower part of the first space 211 has a larger space, the second heat exchange unit 7 can be arranged on the side of the connecting port 81 facing the first space 211, that is, most or substantially all of the second heat exchange unit 7 can be located in the first space 211, which can effectively reduce the distance of the second space 212 in the first direction, which helps to reduce the volume of the air treatment device.

[0150] As feasible, Fig. 9 and Fig.10 As shown, the air treatment device may include: a humidification module 102 disposed in the housing 2. The humidification module 102 is used to humidify the air flowing through the air supply channel. Further, the humidification module 102 may be located downstream of the second heat exchange unit 7. As feasible, the humidification module 102 may be arranged in parallel with the second heat exchange unit 7 at the connecting port 81.

[0151] In a specific embodiment, Fig.11 FIG. 1 is a schematic diagram of the structure of the second heat exchange unit and the humidification module in the embodiment of the utility model. Fig.11As shown, the humidification module 102 may include a mesh structure 1023 made of a material capable of absorbing water, and the mesh structure 1023 is arranged in parallel with the second heat exchange unit 7, so that the mesh structure 1023 can have a larger cross-sectional area for air to flow through, thereby improving the humidification effect. When the air flowing through the air supply channel flows through the mesh structure 1023 after absorbing water, the air can be humidified. The mesh structure 1023 can be close to the second heat exchange unit 7 to reduce the distance of the air treatment device in the first direction, which helps to reduce the volume of the air treatment device.

[0152] like Fig.11 As shown, the humidification module 102 may include: a clamping member 1021, the clamping member 1021 fixes the upper end of the mesh structure 1023; a water distribution pipe 1022, the clamping member 1021 and the water distribution pipe 1022 are arranged in parallel and extend along the second direction, the water distribution pipe 1022 has a water inlet for inputting water, and a plurality of water outlet holes distributed along the second direction are opened on the side wall of the water distribution pipe 1022, so that the water flowing out of the water outlet holes can flow down along the clamping member 1021 to the mesh structure 1023. In this way, water can be simply and conveniently transported to the mesh structure 1023.

[0153] The housing 2 has a humidification water supply port for supplying water to the humidification module 102 . The humidification water supply port is located at the lower part of the side wall of the housing 2 , the bottom of the housing 2 , or the top of the housing 2 .

[0154] As feasible, Fig. 9 As shown, the air treatment device may include: a water receiving tray 104, which is located below the second heat exchange unit 7, the third heat exchange unit 9 and the humidification module 102 to receive the condensed water generated by the second heat exchange unit 7 and the third heat exchange unit 9 and the water humidified by the humidification module 102. The water receiving tray 104 can be arranged at the bottom of the housing 2.

[0155] Further, the air treatment device may include a lift pump. The lift pump is connected to the water receiving tray 104 to drain the water in the water receiving tray 104. As feasible, the lift pump is arranged at the lower part of the first space 211 to fully utilize the space at the lower part of the first space 211, which helps to reduce the volume of the air treatment device.

[0156] As a feasible method, the air treatment device may include: a controller. The controller is used to control the air treatment device. Further, the controller is arranged at the lower part of the first space 211, so as to reduce the volume of the air treatment device.

[0157] The air handling device may include: a strong current connector and a weak current connector arranged on the housing 2. The strong current connector and the weak current connector may be located at the lower part of the housing 2 corresponding to the first space 211, so as to be electrically connected to the controller, the lifting pump, the air supply fan 6 and the driving pump 101.

[0158] As a feasible option, the air supply fan 6 may be a centrifugal fan. Fig. 9 and Fig.10 As shown, the air supply fan 6 and the second heat exchange unit 7 are arranged in parallel and extend in the same direction. Since the thickness of the centrifugal fan is relatively small, the above arrangement can effectively reduce the distance required between the air supply fan 6 and the second heat exchange unit 7 in the direction in which the two are arranged in parallel. Preferably, the ratio range of the thickness of the air supply fan 6 to the diameter of the air supply fan 6 can be selected to be controlled to be less than or equal to 0.45.

[0159] Furthermore, the air supply fan 6 and the second heat exchange unit 7 can extend along the second direction. The second direction is substantially perpendicular to the first direction. In this way, the distance of the second space 212 of the air treatment device in the first direction can be reduced, which helps to reduce the volume of the air treatment device.

[0160] The air outlet of the centrifugal fan may face upward, which is conducive to the output air being transported to the fourth port 210 .

[0161] When the air supply fan 6 can be a centrifugal fan, the centrifugal fan can be an outer rotor fan, which can effectively reduce the distance between the centrifugal fan and the second heat exchange unit 7. The centrifugal fan can also be an inner rotor fan. In this case, in the first direction, the rotor of the centrifugal fan needs to be located between the second heat exchange unit 7 and the volute of the centrifugal fan, which can effectively utilize the space between the centrifugal fan and the second heat exchange unit 7, thereby reducing the distance of the second space 212 of the air treatment device in the first direction.

[0162] As feasible, Fig. 9 and Fig.10 As shown, the connecting port 81 connecting the first space 211 and the second space 212 on the second partition component 8 can be located at the lower part of the second partition component 8. Correspondingly, the air supply fan 6 can be arranged at the lower part of the second space 212. The air supply fan 6 can be substantially corresponding to the height position of the second heat exchange unit 7 at the connecting port 81.

[0163] As a feasible method, the third heat exchange unit 9 can be arranged at a side of the lower part of the first space 211 away from the connecting port 81. The third heat exchange unit 9 can be arranged in the vertical direction. The above method can effectively reduce the wind resistance of the air flowing through the air supply channel, so that more downwardly flowing air flows close to the second partition component 8 and then flows into the connecting port 81.

[0164] Since the area of ​​the air inlet of the air supply fan 6 is smaller than the cross-section of the second heat exchange unit 7 through which the air flows, in order to ensure that the air entering the air inlet of the air supply fan 6 can flow through most of the second heat exchange unit 7 upstream, thereby improving the utilization rate of the second heat exchange unit 7, and it is also necessary to increase the cross-sectional area of ​​the second heat exchange unit 7 in the second direction as much as possible to ensure a sufficient heat exchange rate, the ratio of the area of ​​the air inlet of the air supply fan 6 to the cross-sectional area of ​​the second heat exchange unit 7 in the second direction can be controlled in the range of 0.16-0.24.

[0165] After the supply air flows through the second heat exchange unit 7, it needs to undergo a certain degree of rectification before entering the air inlet of the supply fan 6. Therefore, the supply fan 6 and the second heat exchange unit 7 need to have a certain distance in the first direction. Experiments have found that the distance needs to be greater than or equal to 0.3D and less than or equal to 0.6D, where D represents the diameter of the air inlet of the supply fan 6. This can also make the distance of the second space 212 of the air treatment device in the first direction as small as possible.

[0166] like Fig. 9 As shown, the air treatment device may include: a third filter element 10. The third filter element 10 may be arranged in the second space 212. Preferably, the third filter element 10 may be arranged at the upper part of the second space 212, and the air supply fan 6 may be arranged at the lower part of the second space 212, and the outlet of the air supply fan 6 may face the third filter element 10. The third filter element 10 is used to perform deep and efficient filtration of the air flowing through the air supply channel, for example, a HEPA filter element may be used. The third filter element 10 may be in a V-shaped structure, thereby effectively increasing the filtration area. The third filter element 10 in a V-shaped structure may be installed in the upper part of the second space 212 upright or inverted, which may effectively reduce the distance of the second space 212 in the first direction.

[0167] As feasible, Fig. 9 and Fig.10 As shown, the sealing portion between the wall surface forming the air outlet of the air supply fan 6 and the second partition component 8 can be higher than or equal to the connecting port 81.

[0168] In order to make the air output from the centrifugal fan outlet flow to the fourth port 210 as much as possible, Fig. 9 and Fig.10As shown, the wall of the air outlet of the centrifugal fan is sealed with the housing 2 and / or the second partition assembly 8. Furthermore, the wall of the air outlet of the air supply fan 6 is connected to the second partition assembly 8 through a guide plate 106 on the side facing the second partition assembly 8, and the air passing through the second heat exchange unit 7 flows to the air inlet of the air supply fan 6 under the guiding effect of the guide plate 106. The height of the guide plate 106 tends to gradually decrease in the direction from the second heat exchange unit 7 to the air supply fan 6, so that the air passing through the upper part of the second heat exchange unit 7 directly flows to the air inlet of the air supply fan 6 under the guiding effect of the guide plate 106, reducing the resistance of this part of the air during the flow process and increasing the flow rate of the air flowing through the upper part of the second heat exchange unit 7.

[0169] As a feasible method, at least one door body that can be opened is provided on the front wall of the shell 2, and when the door body is opened, the components in the shell 2 can be replaced or repaired. For example, the first filter element 5, the first heat exchange unit 1, the second filter element 103, the third filter element 10, etc. in the shell 2 can be replaced or repaired. The door body can be connected to other shells 2 by hinges and opened by rotation; the door body can also be opened in the form of a sliding door, and there is no restriction on it in the present application. The first filter element 5, the first heat exchange unit 1 and the third filter element 10 can also be installed in the shell 2 in the same way as the second filter element 103, that is, installed in the shell 2 in an insert-type manner, so as to facilitate replacement or repair when the door body is opened.
