Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioning system. Background Technology

[0002] An air conditioner is a device used to regulate indoor temperature, humidity, airflow speed, and air quality. In summer, air conditioners use a cooling cycle to absorb heat from inside the room and release it outdoors, thereby lowering the indoor temperature. However, when the outdoor temperature is high, air conditioners cannot quickly cool the air to a lower temperature, resulting in the air entering the room being at a higher temperature. Utility Model Content

[0003] This utility model provides an air conditioning system to solve at least one of the aforementioned technical problems.

[0004] The air conditioning system of this utility model includes a housing, a first air conditioning unit, and a second air conditioning unit. The housing has a first chamber and a second chamber isolated from the first chamber. The first chamber has a first air inlet and a first air outlet, and an evaporation duct is formed between the first air inlet and the first air outlet. The second chamber has a first accommodating space and a second accommodating space that are isolated from each other.

[0005] The first air conditioning unit includes a first outdoor heat exchanger and a first indoor heat exchanger. The first outdoor heat exchanger is disposed in the first accommodating space, and the first indoor heat exchanger is disposed in the first chamber and located in the evaporation duct.

[0006] The second air conditioning unit includes a second outdoor heat exchanger and a second indoor heat exchanger. The second outdoor heat exchanger is disposed in the second accommodating space, and the second indoor heat exchanger is disposed in the first chamber and located in the evaporation duct. The second indoor heat exchanger and the first indoor heat exchanger are arranged side by side along the flow direction of the evaporation duct.

[0007] In the air conditioning system of this embodiment, since the first and second accommodating spaces are isolated from each other, the first and second outdoor heat exchangers are less likely to interfere with each other during heat exchange. The airflow into both the first and second outdoor heat exchangers is sufficient, thereby improving their heat exchange efficiency and consequently increasing the heat exchange efficiency of the first and second indoor heat exchangers, thus reducing the temperature of the gas flowing through them. Furthermore, since the second and first indoor heat exchangers are arranged side-by-side along the evaporator duct's flow direction, one of them can pre-treat the flowing gas. The pre-treated gas then passes through the other indoor heat exchanger for further treatment. This segmented gas treatment reduces the gas temperature, resulting in a lower temperature at the first air outlet and consequently a lower temperature for the gas flowing into the room.

[0008] In some embodiments, the housing further includes an outer shell and a first isolation member. The outer shell includes a first wall and a second wall opposite to each other. The first isolation member is connected between two adjacent sides of the first wall and the second wall. The first isolation member and the outer shell located on a first side of the first isolation member form a first chamber. The first isolation member and the outer shell located on a second side of the first isolation member form a second chamber.

The third wall is disposed opposite to the first partition, and the second partition is connected between the two adjacent sides of the first partition and the third wall. The two sides of the second partition are the first accommodating space and the second accommodating space respectively.

[0010] In some embodiments, the first outdoor heat exchanger extends along the inner side of the housing, the second outdoor heat exchanger extends along the inner side of the housing, and there is a gap between the first outdoor heat exchanger and the second outdoor heat exchanger.

The first body has a first opening opposite to the gap, and the first opening is located on the side of the second isolation member near the first accommodating space. The first inspection plate is detachably connected to the first body and covers the first opening.

[0011] In some embodiments, the first air conditioning unit further includes a first compressor, which is connected to both the first outdoor heat exchanger and the first indoor heat exchanger, and is located within the first accommodating space.

[0013] In some embodiments, the second air conditioning unit further includes a second compressor connected to both the second outdoor heat exchanger and the second indoor heat exchanger, and the second compressor is located within the second accommodating space.

[0014] In some embodiments, the first air conditioning unit further includes a first throttling component, and the second air conditioning unit further includes a second throttling component. The first throttling component is connected to the first indoor heat exchanger, and the second throttling component is connected to the second indoor heat exchanger. The first isolation member includes a second body and a third inspection plate detachably connected to the second body. The second body has a second opening, and both the first throttling component and the second throttling component are located at the second opening. The third inspection plate covers the second opening.

The cover plate is detachably connected to the third body and closes the third opening. The air conditioning system also includes a filter assembly located in the first chamber. The filter assembly is arranged side by side with the first indoor heat exchanger and the second indoor heat exchanger along the flow direction of the evaporator duct, and is located upstream of the first indoor heat exchanger and the second indoor heat exchanger. The filter assembly can be removed from the third opening.

[0016] In some embodiments, the filter assembly includes a first baffle, a second baffle, and a third baffle. The first baffle and the second baffle are disposed opposite to each other, and the third baffle is connected to the end of the first baffle and the second baffle on the same side. The third baffle is disposed away from the third opening. The two adjacent sides of the first baffle and the second baffle are provided with sliding grooves. The sliding grooves are disposed between the third baffle and the third opening and extend toward the third opening. The filter assembly is slidably connected to the sliding grooves.

[0032] Air conditioning systems can be split-type air conditioners, central air conditioning systems, industrial air conditioning systems, etc. When the outdoor ambient temperature is high, the air conditioning system may not be able to cool the air to a lower temperature quickly enough, resulting in higher temperatures for the air flowing into the room. For example, an air conditioning system could be a 100% fresh air rooftop air conditioning system. In operation, this system directly exhausts indoor return air to the outside and draws in fresh air from the outside. During this process, because it needs to handle air with a large enthalpy difference, the temperature of the fresh air supplied to the room may be relatively high. For example, in some operating conditions, it is necessary to ensure that the temperature of the fresh air supplied to the room is below 15°C. In related technologies, the temperature of the fresh air supplied to the room may only be above 25°C.

[0033] To address the aforementioned problems, this utility model provides an air conditioning system. The air conditioning system includes a first air conditioning unit and a second air conditioning unit. The first air conditioning unit includes a first indoor heat exchanger. The second air conditioning unit includes a second indoor heat exchanger. One of the first and second indoor heat exchangers can pre-treat the flowing gas, and the pre-treated gas is then processed by the other indoor heat exchanger. This segmented gas treatment method can reduce the gas temperature, thereby resulting in a lower temperature of the gas flowing into the room.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The air conditioning system 100 of this utility model includes a housing 10, a first air conditioning unit 20, and a second air conditioning unit 30. The housing 10 has a first chamber 11 and a second chamber 12 isolated from the first chamber 11. The first chamber 11 has a first air inlet 110 and a first air outlet 111, and an evaporation duct is formed between the first air inlet 110 and the first air outlet 111. The second chamber 12 has a first accommodating space 120 and a second accommodating space 121 that are isolated from each other.

[0035] The first air conditioning unit 20 includes a first outdoor heat exchanger 21 and a first indoor heat exchanger 22. The first outdoor heat exchanger 21 is disposed in the first accommodating space 120, and the first indoor heat exchanger 22 is disposed in the first chamber 11 and located in the evaporation duct.

[0036] The second air conditioning unit 30 includes a second outdoor heat exchanger 31 and a second indoor heat exchanger 32. The second outdoor heat exchanger 31 is disposed in the second accommodating space 121, and the second indoor heat exchanger 32 is disposed in the first chamber 11 and located in the evaporation duct. The second indoor heat exchanger 32 and the first indoor heat exchanger 22 are arranged side by side along the flow direction of the evaporation duct.

[0037] In the air conditioning system 100 of this utility model embodiment, since the first accommodating space 120 and the second accommodating space 121 are isolated from each other, the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 are not likely to interfere with each other during the heat exchange process. The air volume flowing into the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 is relatively sufficient, thereby improving the heat exchange efficiency of the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31, and further improving the heat exchange efficiency of the first indoor heat exchanger 22 and the second indoor heat exchanger 32, so as to reduce the temperature of the gas flowing through the first indoor heat exchanger 22 and the second indoor heat exchanger 32.

[0038] Furthermore, since the second indoor heat exchanger 32 and the first indoor heat exchanger 22 are arranged side by side along the flow direction of the evaporation duct, one of the first indoor heat exchanger 22 and the second indoor heat exchanger 32 can pre-treat the flowing gas. The pre-treated gas is then processed by the other indoor heat exchanger. This segmented gas processing method can reduce the temperature of the gas, thereby making the temperature of the gas flowing to the first air outlet 111 lower, and thus making the temperature of the gas flowing into the room lower.

[0039] Specifically, the enclosure 10 is a device used to house the various components within the air conditioning system 100. The enclosure 10 can isolate the internal and external environments of the air conditioning system 100, thereby reducing the probability that the components inside the enclosure 10 are affected by external environmental factors.

[0040] The first chamber 11 is the space enclosed by the walls of the housing 10. The first chamber 11 can provide flow space for the gas between the first air inlet 110 and the first air outlet 111.

[0041] The air conditioning system 100 may further include an indoor fan assembly 40, which may be disposed within the first chamber 11. The indoor fan assembly 40 serves to form an evaporative air duct between the first air inlet 110 and the first air outlet 111; in other words, the indoor fan assembly 40 can act as the air source for the evaporative air duct. The indoor fan assembly 40 may include a fan and a motor. The motor can drive the fan to rotate, thereby forming an air duct between the first air inlet 110 and the first air outlet 111. In cooling mode, both the first indoor heat exchanger 22 and the second indoor heat exchanger 32 function as evaporators. Therefore, the air duct formed between the first air inlet 110 and the first air outlet 111 is an evaporative air duct.

[0042] Both the first air inlet 110 and the first air outlet 111 can be through holes opened on the first chamber 11. The first air inlet 110 and the first air outlet 111 can face the same direction, which makes the evaporation air duct between the first air inlet 110 and the first air outlet 111 shorter, thereby reducing gas loss during the flow process and ensuring the amount of gas entering the chamber.

[0043] The second chamber 12 is the space enclosed by the walls of the housing 10. The second chamber 12 provides space for the first air conditioning unit 20 and the second air conditioning unit 30. The first air conditioning unit 20 and the second air conditioning unit 30 are two independent air conditioning units. Under cooling conditions, depending on the outdoor ambient temperature, the first air conditioning unit 20 and the second air conditioning unit 30 can operate simultaneously or at different times. For example, when the outdoor ambient temperature is high, the first air conditioning unit 20 and the second air conditioning unit 30 can operate simultaneously.

[0044] The first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 exchange heat simultaneously or at different times, thereby improving the overall heat exchange efficiency of the air conditioning system 100. During the process of passing through the first indoor heat exchanger 22 and the second indoor heat exchanger 32, the gas is cooled, resulting in a lower temperature as it flows to the first air outlet 111. In this process, the first air conditioning unit 20 and the second air conditioning unit 30 can serve as the pre- and post-stages of the cooling operation to further reduce the gas temperature.

[0045] Both the first indoor heat exchanger 22 and the second indoor heat exchanger 32 can be finned heat exchangers or coil heat exchangers, used to exchange heat with the flowing gas. The first indoor heat exchanger 22 and the second indoor heat exchanger 32 can be arranged alternately or connected by fasteners.

[0046] Both the first indoor heat exchanger 22 and the second indoor heat exchanger 32 may include pipes for refrigerant flow. As the gas passes through the first indoor heat exchanger 22 and the second indoor heat exchanger 32, the gas transfers heat to the refrigerant, thus achieving heat exchange. Along the flow direction of the evaporator duct, the first indoor heat exchanger 22 can be located upstream of the second indoor heat exchanger 32. In cooling mode, the gas passes through the first indoor heat exchanger 22 and the second indoor heat exchanger 32 sequentially. After two heat exchanges, the gas temperature can quickly drop to the required range. Here, the flow direction refers to the direction of gas flow in the evaporator duct. The gas flow direction is... Figure 1 , Figure 2 and Figure 4 It is indicated by a dashed line with an arrowhead. It should be noted that... Figure 1 , Figure 2 and Figure 4 The direction of gas flow in the diagram is merely an example for ease of understanding and should not be construed as limiting the embodiments of this utility model.

[0047] In use, outdoor air enters the first chamber 11 through the first air inlet 110. Under the action of the indoor fan assembly 40, the gas forms an evaporative air duct. The gas passes through the first indoor heat exchanger 22 and the second indoor heat exchanger 32 in sequence for heat exchange, and then is discharged into the room from the first air outlet 111.

[0048] Please see Figure 1 and Figure 3 In some embodiments, the housing 10 may include an air vent flange 13, which may be disposed at a first air outlet 111. The air vent flange 13 is disposed around the first air outlet 111 and is used to fix the air duct that leads the gas into the room.

[0049] Please see Figure 4 In some embodiments, the air conditioning system 100 further includes a water pan assembly 50 disposed within the first chamber 11. The first indoor heat exchanger 22 and the second indoor heat exchanger 32 are both placed on the water pan assembly 50. The water pan assembly 50 collects water generated by the first indoor heat exchanger 22 and the second indoor heat exchanger 32 during heat exchange and discharges the water to the outside of the housing 10, thereby reducing the probability of water contamination inside the housing 10. The water pan assembly 50 may be made of stainless steel, which reduces the probability of corrosion and extends its service life.

[0050] Please see Figure 4In some embodiments, the housing 10 further includes an outer shell 14 and a first spacer 15. The outer shell 14 includes a first wall 140 and a second wall 141 opposite to each other. The first spacer 15 connects two adjacent sides of the first wall 140 and the second wall 141. The first spacer 15 and the outer shell 14 located on the first side of the first spacer 15 form a first chamber 11. The first spacer 15 and the outer shell 14 located on the second side of the first spacer 15 form a second chamber 12.

[0051] Thus, by connecting the first wall 140 and the second wall 141, the first partition 15 can divide the housing 10 into a first chamber 11 and a second chamber 12 that are isolated from each other. Furthermore, the first partition 15 can simultaneously serve as the boundary between the first chamber 11 and the second chamber 12, which simplifies the structure of the housing 10, reduces the material required to manufacture the first chamber 11 and the second chamber 12, thereby reducing the weight of the housing 10 and lowering its manufacturing cost.

[0052] Specifically, the outer shell 14 can be the external frame of the housing 10, used to form an accommodating space to protect the components inside the housing 10. The shape of the outer shell 14 can be a regular shape such as a cube or cuboid, or it can be an irregular shape. For example, the shape of the outer shell 14 is a cuboid. The first wall 140 and the second wall 141 can be two opposite sides of a cuboid.

[0053] The first spacer 15 can be a solid metal plate or a multi-segment plate connected by hinges, facilitating folding and unfolding. The first spacer 15 can also be a perforated plate. The perforated plate includes a frame made of metal and mesh openings. A sealing plastic film can be provided at the mesh openings. The plastic film provides the isolation function. It is understood that plastic films have lower manufacturing costs; therefore, making the first spacer 15 a perforated plate can reduce the manufacturing cost of the first spacer 15.

[0054] The first chamber 11, formed by the first isolation member 15, the first wall 140, and the second wall 141, can provide a path for gas flow, allowing the gas to form an evaporation duct and undergo heat exchange through the first indoor heat exchanger 22 and the second indoor heat exchanger 32.

[0055] The first isolation member 15 can be perpendicular to the two adjacent sides of the first wall 140 and the second wall 141, or it can form other angles with the two adjacent sides of the first wall 140 and the second wall 141. When the first isolation member 15 is perpendicular to the two adjacent sides of the first wall 140 and the second wall 141, the first wall 140 and the second wall 141 are arranged in parallel, and the shapes of the first chamber 11 and the second chamber 12 are relatively regular, which facilitates the layout of components such as the first indoor heat exchanger 22, the first outdoor heat exchanger 21, the second indoor heat exchanger 32, and the second outdoor heat exchanger 31.

[0056] The first isolation member 15 can be connected to the first wall 140 and the second wall 141 by non-removable means such as welding or riveting, or it can be connected to the first wall 140 and the second wall 141 by detachable means such as bolt connection or snap-fit.

[0057] Please see Figure 3 and Figure 5 In some embodiments, the first spacer 15 may include a reinforcing rib 150, which may protrude from one side of the first spacer 15. The reinforcing rib 150 can enhance the overall strength of the first spacer 15 and reduce the shaking and deformation of the first spacer 15 during use.

[0058] Please see Figure 5 In some embodiments, the first isolation member 15 has a wire passage hole 151. The wire passage hole 151 is used for various wiring harnesses of the air conditioning system 100 to pass through, so that the wiring harnesses can be threaded into the first chamber 11 and the second chamber 12. The number of wire passage holes 151 can be one or more. When there are multiple wire passage holes 151, the different wire passage holes 151 can be the same or different in size and shape to meet different scenario requirements.

[0059] Please see Figure 4 In some embodiments, the housing 10 further includes a second spacer 16, and the outer shell 14 further includes a third wall 142. The two ends of the third wall 142 are connected to the first wall 140 and the second wall 141, respectively. The third wall 142 is disposed opposite to the first spacer 15. The second spacer 16 is connected between the two adjacent sides of the first spacer 15 and the third wall 142. The two sides of the second spacer 16 are the first accommodating space 120 and the second accommodating space 121, respectively.

[0060] Thus, the first spacer 15 and the second spacer 16 are respectively connected to different walls of the outer casing 14, forming a multi-regional frame structure. This enhances the overall rigidity of the casing 10, helping to resist pressure or impact from the external environment and extending the service life of the equipment. Furthermore, by separating different functional areas with the first spacer 15 and the second spacer 16, the structure of the casing 10 can be simplified compared to using more individual wall panels. This reduces the amount of material used, thereby reducing the weight of the casing 10 and lowering its manufacturing cost.

[0061] Specifically, the second spacer 16 can be a solid metal plate or a multi-segment plate connected by hinges for easy folding and unfolding. The second spacer 16 can also be a perforated plate. The perforated plate includes a frame made of metal and mesh openings. A sealing plastic film can be provided at the mesh openings. The plastic film provides the isolation function. It is understood that plastic films have lower manufacturing costs; therefore, making the second spacer 16 a perforated plate can reduce its manufacturing cost.

[0062] The third wall 142 can be an integrally formed structure with the first wall 140 and the second wall 141, or it can be a separate formed structure. The third wall 142 can be connected to the first wall 140 and the second wall 141 by non-removable means such as welding or riveting, or by detachable means such as bolting or snap-fitting.

[0063] The third wall 142 and the first spacer 15 can have an included angle, or they can be parallel to each other. The second spacer 16 can be connected to the first spacer 15 and the third wall 142 by non-removable means such as welding or riveting, or by detachable means such as bolting or snap-fitting. The second spacer 16 is used to divide the interior of the first chamber 11 into a first accommodating space 120 and a second accommodating space 121, which makes it less likely for the first outdoor heat exchanger 21 located in the first accommodating space 120 and the second outdoor heat exchanger 31 located in the second accommodating space 121 to interfere with each other.

[0064] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, a first outdoor heat exchanger 21 extends along the inner side of the housing 14, and a second outdoor heat exchanger 31 extends along the inner side of the housing 14. A space 122 is provided between the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31. The housing 14 includes a first body 143 and a first access plate 144. The first body 143 is located on the side of the housing 14 near the second chamber 12. The first body 143 has a first opening 1430, which is opposite to the space 122 and is located on the side of the second partition 16 near the first accommodating space 120. The first access plate 144 is detachably connected to the first body 143 and covers the first opening 1430.

[0065] Thus, by providing the first inspection plate 144, users can open the first opening 1430 when maintenance is required, thereby enabling them to inspect and maintain equipment such as the first outdoor heat exchanger 21 located within the first accommodating space 120. When maintenance is not required, the first inspection plate 144 can close the first opening 1430, thereby protecting equipment such as the first outdoor heat exchanger 21 located within the first accommodating space 120 from external environmental influences.

[0066] Specifically, the extension of the first outdoor heat exchanger 21 along the inner side of the outer casing 14 means that the shape of the outer surface of the first outdoor heat exchanger 21 is similar to the shape of the inner side of the outer casing 14, which allows the first outdoor heat exchanger 21 to obtain a larger heat exchange area. Similarly, the extension of the second outdoor heat exchanger 31 along the inner side of the outer casing 14 means that the shape of the outer surface of the second outdoor heat exchanger 31 is similar to the shape of the inner side of the outer casing 14, which also allows the second outdoor heat exchanger 31 to obtain a larger heat exchange area.

[0067] The partition space 122 can prevent mutual interference between the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31. The partition space 122 can facilitate the installation of the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 and reduce the probability of interference between the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 during the installation process.

[0068] The first body 143 is the portion of the outer casing 14 near the second chamber 12. The first body 143 can be a column located on both sides of the first inspection plate 144, or it can be a plate with through holes. The first inspection plate 144 can be detachably connected to the first body 143 via threaded connections, snap-fit ​​connections, or other methods. For example, the first inspection plate 144 has threaded holes. The first body 143 has corresponding threaded holes. Bolts are used to fasten the two threaded holes, thus achieving a detachable connection between the first inspection plate 144 and the first body 143. Insulation material can be provided on the side of the first body 143 near the second chamber 12. The insulation material provides insulation for the second chamber 12.

[0069] The first opening 1430 can be a notch formed by the first body 143. The first opening 1430 can be located in the area corresponding to the space 122. In this way, after opening the first opening 1430, one can directly enter the interior of the second chamber 12 through the space 122, which facilitates maintenance.

[0070] Please see Figure 4 In some embodiments, the first air conditioning unit 20 further includes a first compressor 23, which is connected to both the first outdoor heat exchanger 21 and the first indoor heat exchanger 22, and is located within the first accommodating space 120.

[0071] Thus, since both the first compressor 23 and the first outdoor heat exchanger 21 are located within the first accommodating space 120, the pipe length between them is relatively short, which is beneficial for pipe layout and reduces resistance losses caused by excessively long or bent pipes, allowing for smoother refrigerant flow within the pipes. Furthermore, by removing the first access panel 144, the user can open the first opening 1430 to perform maintenance on the first compressor 23 located within the first accommodating space 120 when necessary.

[0072] Specifically, the first compressor 23 can be a reciprocating compressor, a rotary compressor, a scroll compressor, or other types of compressor. The first compressor 23 is used to compress the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, driving the refrigerant to circulate within the air conditioning system 100. The first compressor 23 can be connected to the first outdoor heat exchanger 21 and the first indoor heat exchanger 22 via pipes.

[0073] In operation, the first compressor 23 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, which is then transported through pipes to the first outdoor heat exchanger 21. In the first outdoor heat exchanger 21, the high-temperature, high-pressure refrigerant exchanges heat with the outdoor air and is cooled into a liquid state. The cooled liquid refrigerant is then transported through pipes to the first indoor heat exchanger 22. In the first indoor heat exchanger 22, the liquid refrigerant exchanges heat with the indoor air, absorbing heat from the room and evaporating into a gaseous state. The gaseous refrigerant returns to the first compressor 23 through pipes, completing one full refrigerant cycle.

[0074] Please see Figure 3 and Figure 4 In some embodiments, the second isolation member 16 includes a fixing plate 160 and a second inspection plate 161. One end of the fixing plate 160 is connected to the first isolation member 15, and the other end of the fixing plate 160 is detachably connected to the second inspection plate 161. The second inspection plate 161 is detachably connected to the first body 143.

[0075] Thus, by providing the second inspection plate 161, users can remove the second inspection plate 161 when maintenance is required, thereby enabling them to inspect and maintain equipment such as the second outdoor heat exchanger 31 located within the second accommodating space 121. When maintenance is not required, the second inspection plate 161 and the fixing plate 160 can separate the first accommodating space 120 and the second accommodating space 121, thereby minimizing mutual interference between the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 during heat exchange.

[0076] In addition, by placing the second inspection plate 161 on the second isolation member 16 instead of on the housing 14, the number of openings on the housing 14 can be reduced, thereby maintaining the structural strength of the housing 14 and reducing the possibility of gas in the second accommodating space 121 directly leaking into the external environment.

[0077] Specifically, the fixing plate 160 and the first isolation member 15 can be connected by non-removable means such as welding or riveting, or by detachable means such as bolting or snap-fitting. The fixing plate 160 and the second maintenance plate 161 can be detachably connected by means such as bolting or snap-fitting. The second maintenance plate 161 and the first body 143 can be detachably connected by means such as bolting or snap-fitting.

[0078] Please see Figure 4 In some embodiments, the second air conditioning unit 30 further includes a second compressor 33, which is connected to both the second outdoor heat exchanger 31 and the second indoor heat exchanger 32, and is located within the second accommodating space 121.

[0079] Thus, since both the second compressor 33 and the second outdoor heat exchanger 31 are located within the second accommodating space 121, the pipe length between the second compressor 33 and the second outdoor heat exchanger 31 is relatively short, which is beneficial for pipe layout and reduces resistance losses caused by excessively long pipes or too many bends, allowing for smoother refrigerant flow within the pipes. Furthermore, the user can remove the second access panel 161 to inspect and repair the second compressor 33 located within the second accommodating space 121.

[0080] Specifically, the second compressor 33 can be a reciprocating compressor, a rotary compressor, a scroll compressor, or other types of compressor. The second compressor 33 is used to compress the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, driving the refrigerant to circulate within the air conditioning system 100. The second compressor 33 can be connected to the second outdoor heat exchanger 31 and the second indoor heat exchanger 32 via pipes.

[0081] In operation, the second compressor 33 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant, which is then piped to the second outdoor heat exchanger 31. In the second outdoor heat exchanger 31, the high-temperature, high-pressure refrigerant exchanges heat with the outdoor air and is cooled into a liquid state. The cooled liquid refrigerant is then piped to the second indoor heat exchanger 32. In the second indoor heat exchanger 32, the liquid refrigerant exchanges heat with the indoor air, absorbing heat from the room and evaporating into a gaseous state. The gaseous refrigerant returns to the second compressor 33 through pipes, completing one full refrigerant cycle.

[0082] Please see Figure 3 and Figure 4In some embodiments, the first air conditioning unit 20 further includes a first throttling component 24, and the second air conditioning unit 30 further includes a second throttling component 34. The first throttling component 24 is connected to the first indoor heat exchanger 22, and the second throttling component 34 is connected to the second indoor heat exchanger 32. The first isolation member 15 includes a second body 152 and a third maintenance plate 153 detachably connected to the second body 152. The second body 152 is provided with a second opening 1520. The first throttling component 24 and the second throttling component 34 are both located at the second opening 1520, and the third maintenance plate 153 covers the second opening 1520.

[0083] Thus, by providing the third inspection plate 153, the user can remove the third inspection plate 153 when maintenance is required to open the second opening 1520, thereby enabling maintenance of the first throttling assembly 24 and the second throttling assembly 34.

[0084] Furthermore, by placing the third inspection plate 153 on the first isolation member 15 instead of on the housing 14, the number of openings on the housing 14 can be reduced, thereby maintaining the structural strength of the housing 14 and reducing the possibility of gas in the first chamber 11 directly leaking into the external environment.

[0085] Specifically, the first throttling component 24 and the second throttling component 34 can be expansion valves or electronic expansion valves, etc. The first throttling component 24 can control the amount of refrigerant entering the first indoor heat exchanger 22 by adjusting its opening degree. The second throttling component 34 can control the amount of refrigerant entering the second indoor heat exchanger 32 by adjusting its opening degree. The first throttling component 24 and the second throttling component 34 can convert high-pressure refrigerant liquid at room temperature into low-temperature and low-pressure liquid, while a small amount of gas will be generated.

[0086] The second body 152 is the main outline of the first isolation member 15. The third access plate 153 can be detachably connected to the second body 152 by means of bolts or snap-fit. For example, the third access plate 153 has threaded holes. The second body 152 has corresponding threaded holes. The two threaded holes are fastened together by bolts to achieve a detachable connection between the third access plate 153 and the second body 152. Sealing foam can be provided at the connection between the third access plate 153 and the second body 152. The sealing foam can seal any gaps that may exist between the third access plate 153 and the second body 152, thereby reducing the probability of mutual interference between the gases in the first chamber 11 and the second chamber 12.

[0087] The second opening 1520 can be a through hole formed on the second body 152. The second opening 1520 can be located in the area corresponding to the first throttling component 24 and the second throttling component 34. This facilitates the maintenance of the first throttling component 24 and the second throttling component 34 at the second opening 1520.

[0088] Please see Figure 2 , Figure 4 and Figure 6 In some embodiments, the housing 14 includes a third body 145 and a cover plate 146. The third body 145 is located on the side of the housing 14 near the first chamber 11 and has a third opening 1450. The cover plate 146 is detachably connected to the third body 145 and covers the third opening 1450. The air conditioning system 100 also includes a filter assembly 60, which is located in the first chamber 11. The filter assembly 60 is arranged side by side with the first indoor heat exchanger 22 and the second indoor heat exchanger 32 along the flow direction of the evaporation duct, and is located upstream of the first indoor heat exchanger 22 and the second indoor heat exchanger 32. The filter assembly 60 can be removed from the third opening 1450.

[0089] Thus, the filter assembly 60 can prevent dust and impurities from the external environment from entering the first indoor heat exchanger 22 and the second indoor heat exchanger 32, thereby reducing the probability of blockage in the first indoor heat exchanger 22 and the second indoor heat exchanger 32, and ensuring the heat exchange effect of the first indoor heat exchanger 22 and the second indoor heat exchanger 32. In addition, since the cover plate 146 is detachably connected to the third body 145, the filter assembly 60 can be replaced, thereby maintaining the filtration effect.

[0090] In addition, the filter assembly 60 is located in the first chamber 11, which improves the utilization of the internal space of the housing 10, thereby making the structure of the housing 10 more compact.

[0091] Specifically, the third body 145 is the portion of the outer casing 14 closest to the first chamber 11. The third opening 1450 can be a through hole formed in the third body 145. The cover plate 146 can be detachably connected to the third body 145 by means of bolts, snap-fit, or other methods. For example, the cover plate 146 has threaded holes. The third body 145 has corresponding threaded holes. The two threaded holes are fastened together by bolts to achieve a detachable connection between the cover plate 146 and the third body 145.

[0092] The filter assembly 60 can be a paper filter, a metal mesh filter, or other types of filter. The filter assembly 60 is used to filter the gas entering the first chamber 11, removing dust and impurities. The filter assembly 60 is located upstream of the first indoor heat exchanger 22 and the second indoor heat exchanger 32, so outdoor air entering the first chamber 11 is first filtered by the filter assembly 60. The outer dimensions of the filter assembly 60 can be smaller than the size of the third opening 1450. The filter assembly 60 can be detachably connected to the housing 14 by bolts, snap-fit, or other means. For example, the filter assembly 60 is bolted to the housing 14. When it is necessary to remove the filter assembly 60, the bolts can be removed to separate the filter assembly 60 from the housing 14.

[0093] Please see Figure 2 and Figure 6 In some embodiments, along the flow direction of the evaporation duct, the filter assembly 60 may include two side-by-side first filters 61 and second filters 62. The first filter 61 is used for pre-filtering the gas. The second filter 62 is used for further filtering the gas. For example, the first filter 61 is a filter screen made of nylon material. The second filter 62 is made of non-woven fabric. In this way, multi-layer filtration can be achieved, and the filtration effect of the filter assembly 60 is improved. Furthermore, the first filter 61 can filter out most dust and impurities, which reduces the amount of dust and impurities reaching the second filter 62, thus extending the service life of the second filter 62.

[0094] In some embodiments, the third body 145 may be provided with insulation cotton on the side near the first chamber 11. The insulation cotton is used to provide insulation for the first chamber 11.

[0095] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the third body 145 is provided with a fourth opening 1451 and a fifth opening 1452. The fourth opening 1451 and the fifth opening 1452 may be notches formed in the third body 145. The housing 14 may also include a fourth access plate 147 and a fifth access plate 148. The fourth access plate 147 covers the fourth opening 1451. The fifth access plate 148 covers the fifth opening 1452. Both the fourth access plate 147 and the fifth access plate 148 are detachably connected to the third body 145. Thus, the user can remove the fourth access plate 147 and the fifth access plate 148 to perform maintenance on the components in the first chamber 11. For example, the fourth access plate 147 may be provided corresponding to the indoor fan assembly 40, which facilitates the maintenance of the indoor fan assembly 40.

[0096] The first inspection plate 144, the second inspection plate 161, the third inspection plate 153, the fourth inspection plate 147, and the fifth inspection plate 148 each correspond to different openings, which makes it easier to inspect, maintain, and replace the components inside the housing 10, thereby improving the maintainability and ease of operation of the air conditioning system 100.

[0097] Handle holes can be provided on the first inspection plate 144, the second inspection plate 161, the third inspection plate 153, the fourth inspection plate 147, and the fifth inspection plate 148. Handles are installed at the handle holes. The handles can be made of plastic. The handles snap onto the inspection plates, which facilitates the installation and removal of the inspection plates.

[0098] Please see Figure 6 In some embodiments, the filter assembly 60 includes a first baffle 63, a second baffle 64, and a third baffle 65. The first baffle 63 and the second baffle 64 are disposed opposite to each other. The third baffle 65 is connected to the end of the first baffle 63 and the second baffle 64 on the same side and is disposed away from the third opening 1450. The two adjacent sides of the first baffle 63 and the second baffle 64 are provided with a sliding groove 66. The sliding groove 66 is disposed between the third baffle 65 and the third opening 1450 and extends into the third opening 1450. The filter assembly 60 is slidably connected to the sliding groove 66.

[0099] Thus, by providing a slide groove 66 between the first baffle 63 and the second baffle 64, and extending from the third baffle 65 to the third opening 1450, the filter assembly 60 can slide in and out along the slide groove 66. This makes the installation and removal of the filter assembly 60 simple and easy. Users only need to gently push or pull the filter assembly 60 along the slide groove 66 to complete the operation, reducing the difficulty of operation and improving the convenience of use.

[0100] Specifically, the first baffle 63, the second baffle 64, and the third baffle 65 are parts of the filter assembly 60 that cooperate with other components. The third baffle 65 can be used to limit the sliding stroke of the filter assembly 60. A groove 66 may be provided on the first baffle 63. A groove 66 may also be provided on the second baffle 64. In the vertical direction, the second baffle 64 may be located below the first baffle 63.

[0101] The opposing sides of the filter assembly can slide and engage with two grooves 66 on the first baffle 63 and the second baffle 64. The first baffle 63 and the second baffle 64 can be set at a predetermined angle. The angle between the first baffle 63 and the second baffle 64 can be set according to the shape of the filter assembly 60. For example, for a cuboid filter assembly 60, the first baffle 63 and the second baffle 64 can be set parallel to each other.

[0102] In some embodiments, the first baffle 63 and the third baffle 65 can be connected to the first indoor heat exchanger 22 via fasteners. In this way, the first indoor heat exchanger 22 can provide stable support for the first baffle 63 and the third baffle 65, allowing the filter assembly 60 to slide stably in the slide groove 66. The first baffle 63 and the third baffle 65 can also be disposed between the filter assembly 60 and the housing 10, so that the first baffle 63 and the third baffle 65 can be used to block airflow, reducing the probability of gas escaping from the gap, thereby increasing the amount of gas passing through the filter assembly 60 and improving the filtration effect.

[0103] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, the housing 10 may include a base 18. The first indoor heat exchanger 22, the second indoor heat exchanger 32, the first outdoor heat exchanger 21, the second outdoor heat exchanger 31, the first compressor 23, the second compressor 33, the housing 14, the first isolator 15, and the second isolator 16 can all be mounted on the base 18 using fasteners. Thus, the base 18 provides support for the aforementioned components.

[0104] In some embodiments, the base 18 may include a forklift slot 180 and a lifting hole 181. The forklift slot 180 is used for transporting the air conditioning system 100 using a forklift. The lifting hole 181 is used for lifting the air conditioning system 100.

[0105] Please see Figure 3 In some embodiments, the air conditioning system 100 may include an outdoor fan assembly 70. The outdoor fan assembly 70 may include two spaced-apart air outlets, which may correspond to the first accommodating space 120 and the second accommodating space 121, respectively. The outdoor fan assembly 70 provides heat dissipation to the second chamber 12. Thus, the first accommodating space 120 and the second accommodating space 121 can receive independent air supply, resulting in sufficient airflow to the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31. The outdoor fan assembly 70 may include two sets of fans, each of which may include a grille, a motor, a motor bracket, and fan blades.

[0106] The second chamber 12 may have a second air inlet 123 and a second air outlet 124. The second air inlet 123 is positioned on the windward side of the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31. The second air outlet 124 is positioned on the air outlet of the outdoor fan assembly 70. A condensing air duct is formed between the second air inlet 123 and the second air outlet 124. The condensing air duct can be formed by the action of the outdoor fan assembly 70. A condensing air duct may be present in the first accommodating space 120. A condensing air duct may also be present in the second accommodating space 121. This allows gas to flow within the first accommodating space 120 and the second accommodating space 121, thereby enabling the first outdoor heat exchanger 21 and the second outdoor heat exchanger 31 to exchange heat.

[0107] Please see Figure 3 In some embodiments, the housing 10 may further include a first top cover plate 19 and a second top cover plate 101, both of which are disposed on the side of the third body 145 opposite to the base 18. The first top cover plate 19 and the second top cover plate 101 are arranged sequentially at intervals along the direction close to the base 18. The surface of the second top cover plate 101 near the first top cover plate 19 may be provided with insulation cotton. The insulation cotton can provide insulation for the second chamber 12. Furthermore, since the insulation cotton is disposed on the surface of the second top cover plate 101 near the first top cover plate 19, the insulation cotton is less likely to fall off due to gas flow in the evaporation duct, which can improve the reliability of the insulation cotton.

[0108] Please see Figure 3 and Figure 4 In some embodiments, the air conditioning system 100 further includes an electrical control box assembly 80 disposed within the first chamber 11. The electrical control box assembly 80 is connected to the base 18 by fasteners and is used for the overall control of the air conditioning system 100. The electrical control box assembly 80 includes a drive board and a main control board. The drive board is used to control the first compressor 23, the second compressor 33, and the indoor fan assembly 40. The electrical control box assembly 80 may be located at the fifth opening 1452, allowing for maintenance by removing the fifth access panel 148 to open the fifth opening 1452.

[0109] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, the housing 14 further includes multiple columns, each erected on one side of the base 18. The columns include a first column 102 and a second column 103. The first column 102 is fixed to the base 18, the first top cover plate 19, and the second top cover plate 101 by fasteners. The second column 103 is fixed to the base 18 and the outdoor fan assembly 70 by fasteners. Thus, the columns provide support for the second top cover plate 101 and the outdoor fan assembly 70, maintaining their stability.
