[0018] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0019] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that a particular feature, structure, material or characteristic associated with the embodiment or example is included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0020] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0021] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0022] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.

[0023] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0024] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0025] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0026] The combined air-conditioning unit is an air-handling device composed of a plurality of separate air-conditioning functional sections corresponding to the equipment, and the plurality of functional sections can be freely combined according to special needs. For example, a plurality of separate air-conditioning functional sections include air mixing, flow balancing, filtration, cooling, primary heating, secondary heating, dehumidification, humidification, air supply, return air, water spraying, silencer, heat recovery, purification, etc. The flow balancing may refer to making the air flow evenly inside the combined air-conditioning unit to avoid local overheating or overcooling. The heat recovery may refer to recovering the heat in the indoor air for utilization. For example, the components related to the plurality of separate air-conditioning functional sections include fans, filters, cooling coils, heating coils and heaters, etc., and the above equipment can be combined as needed to meet different requirements. In addition, the air volume of the combined air-conditioning unit can reach 2000m 3 / h~100000m 3 / h, which is much larger than the air volume of ordinary air conditioners.

[0027] Typically, the housing of a combined air-conditioning unit includes a frame and a panel, and the frame includes thermally-insulated aluminum, tee joints, and straight-through joints, etc., to improve the mechanical strength of the housing. However, the cost of aluminum is high. In some solutions, fiberglass is used instead of aluminum to reduce costs. However, fiberglass is difficult to form a firm connection with fasteners (such as tapping screws). For example, when assembling or overhauling a combined air-conditioning unit, after removing the tapping screws, when the fiberglass frame and panel are fixed again with the tapping screws, sliding wire is likely to occur. In other solutions, steel pipes are manually inserted into the fiberglass frame to improve the fixing effect of the frame and the tapping screws. However, such costs are still relatively high.

[0028] In addition, it is usually necessary to install sealing cotton between the thermally insulated aluminum and the panel to improve the sealing. However, when the pressure inside the box is greater than the pressure outside the box, the sealing cotton will be subjected to the pressure from inside the box to outside the box, resulting in poor resilience of the sealing cotton.

[0029] Furthermore, the interior corners of a modular cabinet are often right-angled, such as the corners where panels meet, or where panels meet the frame. However, since the interior of the cabinet and its components (e.g., filters) need to be cleaned, for example, by flushing or disinfecting the cabinet, right-angled corners are prone to dust accumulation, making cleaning difficult.

[0030] Some embodiments of the present disclosure provide a combined air-conditioning unit 1000. The combined air-conditioning unit 1000 includes a side panel and a connecting assembly, and the connecting assembly is composed of a combination of plastic parts and rigid parts, so as to improve the fixing effect of the connecting assembly and the fastening components, and reduce costs. In addition, the heat-insulating part included in the connecting assembly is filled with heat-insulating material (such as polyurethane), and the material of the sealing part is also polyurethane, so as to improve the sealing effect of the combined air-conditioning unit 1000. And at least a portion of the connecting assembly located inside the box body is arc-shaped, so as to clean the inside of the combined air-conditioning unit 1000. Figure 1 is a block diagram of a combined air-conditioning unit according to some embodiments.

[0031] As shown in FIG1 , the combined air conditioning unit 1000 includes a combined body 1001 and a cabinet 700 . The combined body 1001 is disposed in the cabinet 700 .

[0032] In some embodiments, as shown in FIG1 , the combined body 1001 includes a filter device 1002. For example, the filter device 1002 includes a frame and a filter element. The filter device 1002 is configured to filter airflow entering the combined air conditioning unit 1000. For example, the housing 700 is provided with an air inlet and an air outlet, and the filter device 1002 is positioned near the air inlet. Upon entering the housing 700, airflow is first filtered through the filter device.

[0033] In some embodiments, as shown in FIG1 , the combined body 1001 further includes a heat exchange device 1003. The heat exchange device 1003 is configured to exchange heat with the airflow inside the box 700 to perform cooling or heating. For example, the heat exchange device 1003 includes a heat exchanger.

[0034] In some embodiments, as shown in FIG1 , the combined body 1001 further includes a fan 1004. The fan 1004 is configured to drive airflow to circulate within the housing 700. The fan 1004 draws air from the air inlet, passes through the filter device 1002 and the heat exchange device 1003, and is then discharged from the exhaust port.

[0035] In some embodiments, the housing 700 is provided with a first zone 1010, a second zone 1020, and a third zone 1030. A filter device 1002 is provided in the first zone 1010 to form a filtration section. A heat exchange device 1003 is provided in the second zone 1020 to form a heat exchange section. A fan 1004 is provided in the third zone 1030 to form an air supply section.

[0036] In some embodiments, a fourth area is further provided in the housing 700 to facilitate maintenance of the combined air conditioning unit 1000 .

[0037] In some embodiments, the combined body 1001 further includes a humidifier. The humidifier is configured to increase the humidity of the indoor air to improve the humidity of the indoor air. For example, the humidifier is provided after the heat exchanger.

[0038] In some embodiments, the combined body 1001 further includes a muffler. The muffler is configured to reduce noise generated during operation of the combined air conditioning unit 1000. For example, the muffler is disposed before the third zone 1030.

[0039] In some embodiments, the combined air conditioning unit 1000 is connected to a host to implement corresponding functions.

[0040] In some embodiments, the host includes a compressor configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0041] In some embodiments, the host computer further includes a second heat exchange device. The second heat exchange device is configured to exchange heat with the fluid circulating within the host computer. For example, if the first heat exchange device 1003 functions as an evaporator, the second heat exchange device may function as a condenser. If the first heat exchange device 1003 functions as a condenser, the second heat exchange device may function as an evaporator.

[0042] In some embodiments, the host further includes an expansion valve configured to expand the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant.

[0043] In some embodiments, the combined air conditioning unit 1000 may also be connected to a cooling tower to realize the functions of the combined air conditioning unit 1000. It should be noted that the combined air conditioning unit 1000 may be connected to different components according to actual needs, and this disclosure does not limit this.

[0044] Figure 2 is a perspective view of a combined air conditioning unit according to some embodiments. Figure 3 is another perspective view of a combined air conditioning unit according to some embodiments. Figure 4 is yet another perspective view of a combined air conditioning unit according to some embodiments.

[0045] In some embodiments, as shown in Figures 2 to 4, the box body 700 includes a plurality of side panels 200. The plurality of side panels 200 are connected to each other to form the box body 700. For example, the box body 700 is in the shape of a rectangular parallelepiped.

[0046] For example, as shown in Figures 2 to 4, the plurality of side panels 200 include four first side panels 201, a second side panel 202, and a third side panel 203. The four first side panels 201 are sequentially connected to form the side walls of the box body 700. The second side panels 202 are disposed on the upper ends of the four first side panels 201 to form the top wall of the box body 700. The third side panel 203 is parallel to the second side panels 202 and is disposed on the lower ends of the four first side panels 201 to form the bottom wall of the box body 700.

[0047] In some embodiments, the box body 700 further includes a reinforcement beam disposed on the third side plate 203 and connected between two opposite first side plates 201 among the four first side plates 201 to enhance the structural strength of the box body 700 .

[0048] In some embodiments, as shown in Figures 2 and 3, the first side panel 201 includes a plurality of first sub-side panels 250. The plurality of first sub-side panels 250 are arranged along the length or width of the box body 700, and the plurality of first sub-side panels 250 are connected to form the first side panel 201. The length of the box body 700 may refer to the left-right direction in Figure 3, and the width of the box body 700 may refer to the front-back direction in Figure 3.

[0049] 3 , the second side panel 202 includes a plurality of second sub-side panels 260 . The plurality of second sub-side panels 260 are arranged along the length or width of the box body 700 and are connected to form the second side panel 202 .

[0051] Since the combined air-conditioning unit 1000 has many components inside and is relatively large in size, the installation and transportation of the combined air-conditioning unit 1000 can be facilitated by dividing the side panel 200 into multiple sub-side panels and assembling the multiple sub-side panels.

[0052] In some embodiments, the second side panel 202 and the third side panel 203 are respectively filled with insulation materials (eg, rigid polyurethane foam or rock wool) to enhance the insulation effect of the box body 700 .

[0053] In some embodiments, the second side panel 202 and the third side panel 203 are respectively filled with a material with high rigidity (eg, polyvinyl chloride (PVC) or glass fiber reinforced plastics (GFRP)) to enhance the rigidity of the box body 700 .

[0054] In some embodiments, as shown in FIG2 , the combined air conditioning unit 1000 further includes a base 100 . The base 100 is disposed on a side (bottom side) of the third side plate 203 away from the second side plate 202 to support the cabinet 700 .

[0055] In some embodiments, the base 100 includes a supporting member. For example, the supporting member includes a plurality of beams, and the plurality of beams are welded or bolted together to form the base 100. For example, the plurality of beams include horizontal beams and longitudinal beams to prevent the modular air conditioning unit 1000 from tilting or being damaged when loaded and moved by a transport device (e.g., a forklift).

[0056] In some embodiments, the third side panel 203 in the box body 700 may be omitted, and the plurality of first side panels 201 are respectively disposed on the base 100 to facilitate assembly of the box body 700 .

[0057] In some embodiments, the combined air conditioning unit 1000 further includes a shock absorber disposed between the housing 700 and the base 100. The shock absorber is configured to reduce vibrations during opening, closing, and operation of the combined air conditioning unit 1000.

[0058] Figure 5 is a perspective view of a first connecting member and a plurality of side panels according to some embodiments. Figure 6 is a cross-sectional view of a first connecting member and a plurality of side panels according to some embodiments.

[0059] In some embodiments, as shown in Figures 5 and 6, the side panel 200 includes a first connecting plate 210 and a second connecting plate 220. The first connecting plate 210 is a rigid member and serves as the inner wall of the side panel 200. The second connecting plate 220 is a rigid member and serves as the outer wall of the side panel 200, and is spaced apart from the first connecting plate 210. The length of the second connecting plate 220 is greater than the length of the first connecting plate 210 in the direction in which the side panel 200 extends.

[0060] 6 , the first connecting plate 210 includes a first bending portion 2100 . An end of the first connecting plate 210 close to the first connecting member 300 is bent toward the second connecting plate 220 to form the first bending portion 2100 .

[0064] Figure 7 is another perspective view of a combined air conditioning unit according to some embodiments. Figure 8 is a partial enlarged view of circle A in Figure 7. Figure 9 is a structural diagram of an adapter according to some embodiments.

[0065] In some embodiments, as shown in Figures 7 to 9, the connecting assembly 3000 includes at least one first connecting component 300. The at least one first connecting component 300 is disposed between adjacent side panels 200 and connects the adjacent side panels 200. The angle between the adjacent side panels 200 connected by the first connecting component 300 is a right angle. Of course, the angle between the adjacent side panels 200 connected by the first connecting component 300 can also be other angles.

[0066] The following description will be made by taking the example that the adjacent side panels 200 connected by the first connecting member 300 are perpendicular to each other.

[0067] In some embodiments, the first connecting member 300 is a plastic member. The material of the plastic member includes a composite material, for example, fiberglass reinforced plastic (FRP). FRP is a composite of resin and glass fiber, and has low thermal conductivity and high strength. For another example, the material of the plastic member includes plastic, for example, polyvinyl chloride, polyphenylene sulfide (PPS), polyvinyl alcohol (PVA), polypropylene (PP), or polyethylene (PE).

[0068] Figure 10 is a structural diagram of the first connecting component according to some embodiments. In some embodiments, as shown in Figures 5, 6, and 10, the first connecting component 300 includes a first connecting body 350 and a first plug-in portion 310. The first plug-in portion 310 is provided on a side of the first connecting body 350 away from the interior of the box 700.

[0069] In some embodiments, as shown in Figures 6 and 10, the first plug-in portion 310 includes a first reinforcement portion 360 and a first insertion cavity 3103. The first reinforcement portion 360 is connected to the first connecting body 350, and the first reinforcement portion 360 and the first connecting body 350 enclose the first insertion cavity 3103. The first reinforcement portion 360 is connected to the adjacent side panel 200. For example, the first connecting component 300 also includes a first fastening portion 340, which passes through the side panel 200 and is connected to the first reinforcement portion 360.

[0070] In some embodiments, as shown in Figures 6 and 10, the first reinforcement portion 360 includes a first sub-reinforcement portion 361 and a second sub-reinforcement portion 362. One end of the first sub-reinforcement portion 361 is connected to the first connecting body 350, and the other end is connected to one end of the second sub-reinforcement portion 362. The other end of the second sub-reinforcement portion 362 is connected to the first connecting body 350. The first sub-reinforcement portion 361, the second sub-reinforcement portion 362, and one side of the first connecting body 350 form a first insertion cavity 3103. In this case, the first connecting component 300 may include two first fastening portions 340, one of which passes through one of the adjacent side panels 200 and is connected to the first sub-reinforcement portion 361, and the other first fastening portion 340 passes through the other of the adjacent side panels 200 and is connected to the second sub-reinforcement portion 362.

[0071] In some embodiments, an angle is formed between the first reinforcement sub-portion 361 and the second reinforcement sub-portion 362. For example, the first reinforcement sub-portion 361 and the second reinforcement sub-portion 362 are perpendicular to each other.

[0072] In some embodiments, as shown in Figures 5, 6, and 10, the first connecting member 300 further includes a first heat-insulating portion 320. The first heat-insulating portion 320 is disposed within the first connecting body 350 and spaced apart from the first plug-in portion 310. The first heat-insulating portion 320 is closer to the interior of the housing 700 than the first plug-in portion 310. The first heat-insulating portion 320 is configured to block heat transfer between the interior and exterior of the housing 700, thereby maintaining heat within the housing 700.

[0073] In some embodiments, the first heat-insulating portion 320 is a cavity, and the cavity is filled with heat-insulating material to achieve heat preservation, thereby achieving heat preservation in the box 700. For example, the heat-insulating material includes polyurethane or rock wool.

[0074] 6 and 10 , the first connecting body 350 includes a plurality of first inclined portions 351. The plurality of first inclined portions 351 are surfaces of the first connecting body 350 close to the adjacent side panels 200 and are inclined relative to the box body 700 from the inside to the outside.

[0075] In some embodiments, as shown in FIG. 6 and FIG. 10 , the interval D1 between the plurality of first inclined portions 351 increases from the inside to the outside of the box body 700 .

[0076] In some embodiments, as shown in Figures 5, 6, and 10, the first connecting body 350 further includes a transition surface 380. The transition surface 380 is the side surface of the first connecting body 350 that is adjacent to the interior of the housing 700. For example, the transition surface 380 may be curved and recessed toward the first plug-in portion 310. Providing the curved transition surface 380 within the housing 700 effectively reduces dust accumulation and cleaning difficulties, while also improving the smoothness of the interior surface of the housing 700.

[0077] In some embodiments, as shown in FIG10 , the first connecting member 300 further includes a first engaging portion 370. The first engaging portion 370 is disposed between the first connecting body 350 and the first reinforcing portion 360. For example, the first engaging portion 370 is disposed on a side of the side panel 200 at the connection position between the first connecting body 350 and the first reinforcing portion 360, and the first engaging portion 370 is a engaging groove having an arcuate or semicircular shape.

[0078] In some embodiments, as shown in Figures 7 to 9, at least one first connecting component 300 includes a plurality of first connecting components 300, and the connecting assembly 3000 further includes a first adapter 500. The first adapter 500 is plugged into the first plugging portion 310 of the intersecting first connecting components 300 to connect the intersecting first connecting components 300. The intersecting first connecting components 300 include three first connecting components 300 that connect adjacent side panels of three mutually perpendicular side panels 200.

[0079] In some embodiments, as shown in Figures 7 to 9 , the first adapter 500 can include a tee. Because the ends of the first connecting components 300 located in three mutually perpendicular planes converge at the corners of the housing 700, the tee includes three protrusions 501 that protrude in three mutually perpendicular directions. These three protrusions can be inserted into the first plug-in portions 310 of the three first connecting components 300 that converge at the corners of the housing 700, thereby connecting the three first connecting components 300.

[0080] In some embodiments, the connection assembly 3000 further includes a sealing gasket, which is disposed at a connection position between the first adapter 500 and the first connection component 300 to achieve sealing of the box body 700 .

[0081] In some embodiments, as shown in FIG6 , the first thermal insulation member 230 includes a first thermal insulation body 231. The first thermal insulation body 231 includes a second inclined portion 232. The second inclined portion 232 is a surface of the first thermal insulation body 231 that is close to the first connecting member 300. The second inclined portion 232 is substantially parallel to one of the plurality of first inclined portions 351 and is in contact with the first inclined portion 351.

[0082] In some embodiments, as shown in FIG6 , the first thermal insulator 230 further includes a first extension 233. A portion of the first thermal insulator body 231 on a side away from the first cavity 2300 extends away from the first cavity 2300 to form the first extension 233. The second bent portion 2200 wraps around the end of the first extension 233 away from the first cavity 2300 to increase the strength of the first thermal insulator 230.

[0083] In some embodiments, as shown in FIG6 , the first thermal insulation member 230 further includes a third bent portion 236. The third bent portion 236 is disposed on a side of the first thermal insulation body 231 away from the first connecting member 300. The third bent portion 236 extends away from the first connecting member 300 and bends toward the first connecting plate 210 to form the third bent portion 236. The third bent portion 236 engages with the first bent portion 2100.

[0084] 6 , the first thermal insulation member 230 further includes a plurality of first sealing portions 234 . The plurality of first sealing portions 234 are disposed on the second inclined portion 232 and are equidistantly arranged along the extension direction of the second inclined portion 232 . The plurality of first sealing portions 234 abut against the first inclined portion 351 .

[0085] In some embodiments, the plurality of first sealing portions 234 may be semicircular or arc-shaped.

[0086] In this way, when the first connecting member 300 is disposed between the two side plates 200 , the plurality of second inclined portions 232 fits with the plurality of first inclined portions 351 to squeeze the first sealing portion 234 , thereby improving the sealing effect of the box body 700 .

[0087] In some embodiments, as shown in FIG6 , the first thermal insulation member 230 further includes a second sealing portion 235. The second sealing portion 235 is disposed at an end of the second inclined portion 232 away from the box body 700.
