Description

Technical Field

[0001] The utility model relates to the technical field of air treatment and supply, in particular to an air treatment device. Background Art

[0002] In the field of modern air handling devices, in order to improve energy efficiency and indoor air quality, a first heat exchange unit such as a total heat exchanger is 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 total heat exchanger is to transfer the heat (or coldness) in the return air to the fresh air through special heat exchange materials, thereby reducing the energy consumption required for fresh air processing. In addition, the air handling device also needs to adjust the temperature of the supply air formed by the fresh air and the return air, and transport it to the air outlet for output through the supply air fan, so a corresponding second heat exchange unit and supply air fan are required; in addition, the air handling device also needs to exchange heat between the input refrigerant and the input heat exchange medium through the third heat exchange unit, so that the heat exchange medium with changed temperature can be supplied to the terminal device.

[0003] In order to meet the above-mentioned multiple functions, the most significant problem for air handling devices is that the entire air handling device is too large. 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. In summary, it can be seen that the problem of the large volume of the air handling device has become an important factor restricting its wider application and development. Utility Model Content

[0061] In order to solve the problem of large volume of air handling device, an air handling device is proposed in the present application. Figure 1 This is a schematic diagram of the structure of the air treatment device in a feasible implementation mode in the embodiment of the utility model. Figure 2 for Figure 1 The schematic diagram of the local structure of the lower part of the first space, the lower part of the second space and the connecting port is as follows: Figure 1 and Figure 2 As shown, the air handling device may include: a shell 2, the shell 2 having a return air port 23, a fresh air port 21, an exhaust port 22, and an air supply port 27; a first partition component 8, the first partition component 8 partitions the shell 2 into a first space 28 and a second space 29 distributed along a first direction, the first partition component 8 having a connecting port 81 connecting the first space 28 and the second space 29; a first heat exchange unit 1 having a first heat exchange channel 11 and a second heat exchange channel 12, the first heat exchange unit 1 being arranged at the upper part of the first space 28; an air supply fan 6, the air supply fan 6 being arranged in the second space 29; a second heat exchange unit 7, the second heat exchange unit 7 being arranged in the shell 2; and a third heat exchange channel 11 having a first heat exchange channel 11 and a second heat exchange channel 12. and a third heat exchange unit 9 of the fourth heat exchange channel, the third heat exchange unit 9 is arranged in the lower part of the first space 28, and the shell 2 has a refrigerant inlet 210 and a refrigerant outlet 211 for supplying and recovering refrigerant to the third heat exchange channel and the second heat exchange unit 7, and a heat exchange medium inlet 212 and a heat exchange medium outlet 213 for supplying and recovering heat exchange medium to the fourth heat exchange channel; the fresh air flowing in from the fresh air inlet 21 and passing through the first heat exchange channel 11 and / or the return air flowing in from the return air inlet 23 can pass through the second heat exchange unit 7, the connecting port 81, and the air supply fan 6 and then be discharged from the air supply port 27, and the return air flowing in from the return air inlet 23 can pass through the second heat exchange channel 12 and be discharged from the exhaust port 22.

[0062] The air handling device in the present application separates the first space 28 and the second space 29 distributed along the first direction in the shell 2 through the first partition component 8, and the first partition component 8 has a connecting port 81 connecting the first space 28 and the second space 29. In this way, the first heat exchange unit 1 can be arranged in the upper part of the first space 28, the air supply fan 6 is arranged in the second space 29, and the third heat exchange unit 9 is arranged in the lower part of the first space 28. The third heat exchange unit 9 is used to exchange heat between the input refrigerant and the input heat exchange medium, so that the heat exchange medium with changed temperature can be output to the terminal device. The second heat exchange unit 7 is arranged in the shell 2. Through the above-mentioned method, not only can the air treatment device meet the requirements that the fresh air flowing in from the fresh air inlet 21 and passing through the first heat exchange channel 11 and / or the return air flowing in from the return air inlet 23 is discharged from the supply air inlet 27 after passing through the second heat exchange unit 7, the connecting port 81, and the air supply fan 6, but the return air flowing in from the return air inlet 23 can be discharged from the exhaust port 22 through the second heat exchange channel 12; moreover, through the reasonable division of the space inside the shell 2, combined with the reasonable arrangement of the first heat exchange unit 1, the air supply fan 6, the third heat exchange unit 9 and the second heat exchange unit 7 in the space inside the shell 2, the space inside the air treatment device can be reasonably and fully utilized, and the entire device can be more compact and smaller in size.

[0063] In order to better understand the air treatment device in this application, it will be further explained and illustrated below. Figure 1 and Figure 2 As shown, the shell 2 may be hollow, and its interior may be used to set components such as the first heat exchange unit 1, the air supply fan 6, the third heat exchange unit 9, the second heat exchange unit 7 and the second partition assembly 3. The shell 2 may have a return air port 23, a fresh air port 21, an exhaust air port 22 and an air supply port 27. The return air port 23, the fresh air port 21, the exhaust air port 22 and the air supply port 27 may be located at any position on the shell 2, and are not limited in this application. The return air port 23 is used to input return air into the shell 2; the fresh air port 21 is used to input fresh air into the shell 2; the exhaust air port 22 is used to discharge exhaust air formed by at least part of the return air in the shell 2 out of the shell 2; the air supply port 27 is used to output the supply air formed by the return air and / or fresh air in the shell 2 to supply it to the required area.

[0064] As preferably, Figure 1As shown, the return air inlet 23, the fresh air inlet 21, the exhaust air outlet 22 and the air supply outlet 27 can be 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 return air inlet 23, the fresh air inlet 21, the exhaust air outlet 22 and the air supply outlet 27 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, so that the entire air treatment device can be connected to the air ducts. The overall appearance is both beautiful and simple.

[0065] like Figure 1 As shown, the first partition component 8 divides the shell 2 into a first space 28 and a second space 29 distributed along the first direction. The first partition component 8 can be arranged in the shell 2 and sealedly connected to the shell 2. The first partition component 8 extends in the vertical direction. The first partition component 8 has a connecting port 81 connecting the first space 28 and the second space 29. The first direction can be a left-right width direction or a front-back thickness direction.

[0066] like Figure 1 As shown, the first heat exchange unit 1 is arranged at the upper part of the first space 28. The first heat exchange unit 1 may have a first heat exchange channel 11 and a second heat exchange channel 12. Part of the first space 28, the connecting port 81 and the second space 29 form an air supply channel, one end of the air supply channel is connected to the outlet of the first heat exchange channel 11 and the return air port 23, and the other end of the air supply channel is connected to the air supply port 27, and the air supply channel is U-shaped.

[0067] The gas flowing through the first heat exchange channel 11 can exchange heat with the gas flowing through the second heat exchange channel 12. The inlet of the first heat exchange channel 11 can be connected to the fresh air port 21, the inlet of the second heat exchange channel 12 can be connected to the return air port 23, and the outlet of the second heat exchange channel 12 can be connected to the exhaust port 22. The outlet of the first heat exchange channel 11 is connected to the return air port 23 and the air supply port 27. A supply air channel is formed in the downstream area of ​​the outlet of the first heat exchange channel 11 in the first space 28.

[0068] like Figure 1As shown, the air supply fan 6 can be arranged in the second space 29. The air supply fan 6 is used to generate air supply pressure, so that the return air input from the return air port 23 and the fresh air input from the fresh air port 21 can flow to the air supply channel, and then output from the air supply port 27. The second heat exchange unit 7 is arranged in the shell 2. The second heat exchange unit 7 is used to adjust the temperature and / or humidity of the air flowing through the air supply channel. Refrigerant or other heat exchange medium can flow into the second heat exchange unit 7. The third heat exchange unit 9 is arranged at the lower part of the first space 28. The fresh air flowing in from the fresh air port 21 and passing through the first heat exchange channel 11 and / or the return air flowing in from the return air port 23 can be discharged from the air supply port 27 after passing through the second heat exchange unit 7, the connecting port 81, and the air supply fan 6, and the return air flowing in from the return air port 23 can be discharged from the exhaust port 22 through the second heat exchange channel 12.

[0069] Specifically, the fresh air entering from the fresh air port 21 needs to enter the first heat exchange channel 11 of the first heat exchange unit 1, and at least part of the return air entering from the return air port 23 needs to enter the second heat exchange channel 12 of the first heat exchange unit 1. The two are heat exchanged 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 22 after passing through the corresponding channel. The fresh air after heat exchange is mixed with the remaining return air entering from the return air port 23 to form supply air, which then passes through the first space 28, the connecting port 81, and the second space 29 and is output from the supply air port 27. Before the supply air is output from the supply air port 27, the supply air passes through the second heat exchange unit 7 and the supply air fan 6. When the supply air passes through the second heat exchange unit 7, the temperature and / or humidity of the supply air can be adjusted by the second heat exchange unit 7 as needed.

[0070] Of course, in the above process, only the return air may pass through the second heat exchange unit 7 and the air supply fan 6 and then be discharged from the air supply port 27; or only the fresh air may pass through the second heat exchange unit 7 and the air supply fan 6 and then be discharged from the fourth port.

[0071] As feasible, the return air inlet 23, the fresh air inlet 21, and the exhaust air inlet 22 are located on the housing 2 corresponding to the first space 28. The air supply inlet 27 can be located on the housing 2 corresponding to the second space 29.

[0072] As feasible, Figure 4 FIG. 1 is a schematic structural diagram of the upper portion of the first space of the air treatment device in an embodiment of the utility model in a feasible implementation manner, such as Figure 1 and Figure 4 As shown, the air treatment device may include a second partition component 3. The second partition component 3 is disposed in the housing 2. The second partition component 3 and the first heat exchange unit 1 separate the housing 2 into a fresh air channel 24, a return air channel 26 and an exhaust air channel 25 that are connected to the fresh air inlet 21, the return air inlet 23 and the exhaust air outlet 22 in a one-to-one correspondence.

[0073] The fresh air channel 24 is connected to the inlet of the first heat exchange channel 11, and the exhaust air channel 25 is connected to the outlet of the second heat exchange channel 12; the return air channel 26 is connected to the outlet of the first heat exchange channel 11 and the inlet of the second heat exchange channel 12. The second partition component 3 has a bypass port 32 connecting the fresh air channel 24 and the return air channel 26. Figure 1 and Figure 4 As shown, the air treatment device also includes: a switching component 4, which can control the connection and disconnection between the fresh air outlet 21 and the return air channel 26 through the bypass port 32, and / or the connection and disconnection between the fresh air outlet 21 and the inlet of the first heat exchange flow channel 11. When the fresh air input from the fresh air outlet 21 to the fresh air channel 24 does not need to pass through the first heat exchange unit 1, the fresh air can directly enter the return air channel 26 through the bypass port 32, thereby mixing with the return air, and then forming 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. At this time, the fresh air does not need to exchange heat with the return air.

[0074] In a specific embodiment, the switching component 4 may include a first air valve 41 and a second air valve 42 disposed at the bypass port 32. The first air valve 41 is disposed in the fresh air channel 24 and can control the opening and closing of the fresh air 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.

[0075] Specifically, if Figure 4 As shown, the second partition component 3 can divide the fresh air channel 24 into a diversion space 241 and a connecting space 242. The second partition component 3 can have a main port 31, which connects the diversion space 241 and the connecting space 242. The main port 31 is installed with a first air valve 41. The fresh air port 21 connects the main port 31 and the bypass port 32 through the diversion space 241. The connecting space 242 connects the main port 31 and the inlet of the first heat exchange flow channel 11.

[0076] As feasible, Figure 1 and Figure 4 As shown, the air treatment device may include a first filter element 5 disposed in the fresh air channel 24, and the fresh air flowing in from the fresh air outlet 21 may be filtered by the first filter element 5. The filtered fresh air may be mixed with the return air to form the supply air. Further, the filtered fresh air may enter the first heat exchange flow channel 11, and the fresh air flowing out of the first heat exchange flow channel 11 may be mixed with the return air to form the supply air. As feasible, the fresh air flowing in from the fresh air outlet 21 may directly enter the return air channel 26 through the bypass port 32 without being filtered by the first filter element 5, thereby mixing with the return air to form the supply air.

[0077] The third heat exchange unit 9 has a third heat exchange channel and a fourth heat exchange channel. Figure 2As shown, the housing 2 may have a refrigerant inlet 210 and a refrigerant outlet 211 for supplying and recovering refrigerant to the third heat exchange channel and the second heat exchange unit 7, and a heat exchange medium inlet 212 and a heat exchange medium outlet 213 for supplying and recovering heat exchange medium to the fourth heat exchange channel. The heat exchange medium input from the heat exchange medium inlet 212 flows through the fourth heat exchange channel, and exchanges heat with the refrigerant input from the refrigerant inlet 210 to the third heat exchange channel. The heat exchange medium after heat exchange flows out from the heat exchange medium outlet 213 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 211, flows to the compressor and heat exchange unit in the outdoor unit, and then flows back into the refrigerant inlet 210.

[0078] As feasible, the refrigerant inlet 210, the refrigerant outlet 211, the heat exchange medium inlet 212 and the heat exchange medium outlet 213 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 210, the refrigerant outlet 211, the heat exchange medium inlet 212 and the heat exchange medium outlet 213 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.

[0079] 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.

[0080] In order to drive the heat exchange medium to flow to supply to the terminal device, as feasible, such as Figure 1 and Figure 2 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 28.

[0081] As feasible, Figure 1As shown, the air treatment device may include: a second filter element 103, which is arranged in the first space 28 between the second heat exchange unit 7 and the first heat exchange unit 1 in the vertical direction. Further, the connecting port 81 may be located at the lower part of the first partition assembly 8, and the connecting port 81 is located below the second filter element 103. At this time, the second filter element 103 may be arranged in the middle of the first space 28. Specifically, the second filter element 103 may be arranged in the middle of the first space 28 along the horizontal direction. The air in the air supply channel may continue to flow downward after being filtered by the second filter element 103. The second filter element 103 may filter both the return air and the fresh air. Further, the filtering accuracy of the second filter element 103 may be higher than the filtering accuracy of the first filter element 5. The second filter element 103 may be installed in the middle of the first space 28 in an inserted manner. The second filter element 103 can be inserted into the first space 28 in the housing 2 along the second direction, and can also be withdrawn from the first space 28 in the housing 2 along the second direction, so that the second filter element 103 can be easily replaced.

[0082] As feasible, Figure 1 and Figure 2 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 28 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 28, that is, most or substantially all of the second heat exchange unit 7 can be located in the first space 28, which can effectively reduce the distance of the second space 29 in the first direction, which helps to reduce the volume of the air treatment device.

[0083] As feasible, Figure 1 and Figure 2 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.

[0084] In a specific embodiment, Figure 3 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. Figure 3As 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.

[0085] like Figure 3 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.

[0086] 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 .

[0087] As feasible, Figure 1 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.

[0088] Further, the air handling 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 28 to fully utilize the space at the lower part of the first space 28, which helps to reduce the volume of the air handling device.

[0089] 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 28, so as to reduce the volume of the air treatment device.

[0090] 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 28, so as to be electrically connected to the controller, the lifting pump, the air supply fan 6 and the driving pump 101.

[0091] As feasible, Figure 1 As shown, the air supply fan 6 can be a centrifugal fan. 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 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 can be effectively reduced through the above arrangement. 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.

[0092] Further, 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. Further, the second direction and the first direction are both located in a horizontal plane. In this way, the distance of the second space 29 of the air treatment device in the first direction can be reduced, which helps to reduce the volume of the air treatment device. The air outlet of the centrifugal fan can be oriented upward, which is conducive to the output air being transported to the air supply port 27.

[0093] 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 29 of the air treatment device in the first direction.

[0094] When the connecting port 81 connecting the first space 28 and the second space 29 on the first partition component 8 is located at the lower part of the first partition component 8, the air supply fan 6 can be correspondingly arranged at the lower part of the second space 29. 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.

[0095] As a feasible method, the third heat exchange unit 9 can be arranged at a side of the lower part of the first space 28 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 first partition component 8 and then flows into the connecting port 81.

[0096] 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.

[0097] 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 29 of the air treatment device in the first direction as small as possible.

[0098] like Figure 1 As shown, the air treatment device may include: a third filter element 10. The third filter element 10 may be arranged at the upper part of the second space 29, and the outlet of the air supply fan 6 faces 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 29 upright or inverted, which may effectively reduce the distance of the second space 29 in the first direction.

[0099] As feasible, Figure 1 As shown, the sealing portion between the wall surface forming the air outlet of the air supply fan 6 and the first partition component 8 can be higher than or equal to the connecting port 81.

[0100] In order to make the air output from the air outlet of the centrifugal fan flow to the air supply port 27 as much as possible, a seal is formed between the wall surface of the air outlet of the centrifugal fan and the housing 2 and / or the first partition assembly 8. Furthermore, the wall surface of the air outlet of the air supply fan 6 is connected to the first partition assembly 8 through a guide plate 106 on the side facing the first 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.

[0101] 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.
