[0036] Usually, the fresh air components of fresh air air conditioners mostly use one-way flow to replace fresh air, that is, fresh air is sucked into the room through the fresh air components, and the old air in the room is discharged from the room through the gaps in the doors and windows of the room. As a result, fresh air air conditioners using one-way ventilation often have low fresh air volume and insufficient one-way ventilation volume.

[0037] In the related art, the wall-penetrating pipe part of the fresh air duct adopts a hard pipe, and the wall-penetrating pipe part is divided into an open receiving groove and a closed fresh air cavity. After the refrigerant pipe, the wire pipe and the drain pipe are placed in the receiving groove, a cover needs to be added to the top of the wall-penetrating pipe to make the receiving groove a closed space to protect the refrigerant pipe, the wire pipe and the drain pipe. The operation is complicated and increases the cost.

[0038] Hereinafter, an air conditioner according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0039] As shown in Figures 16 to 20 , the air conditioner includes a refrigerant circuit, an outdoor unit and an indoor unit 10.

[0040] In the refrigerant circuit, the refrigerant circulates sequentially through the compressor, condenser, pressure reducer and evaporator, one of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger; and the outdoor unit is located on the outdoor side, and the outdoor unit includes a first shell and an outdoor fan, a compressor and an outdoor heat exchanger arranged in the first shell.

[0041] The first housing is formed with an outdoor air inlet and an outdoor air outlet. For example, the outdoor air inlet and the outdoor air outlet are provided on a surface of the first housing. The outdoor air outlet is located on a side of the first housing facing the outdoors, so that outdoor air enters the first housing through the outdoor air inlet and then enters the outdoors through the outdoor air outlet.

[0042] The indoor unit 10 is located indoors and includes a second housing, an indoor fan, an indoor heat exchanger, and a fresh air assembly disposed therein. The second housing is formed with an indoor air inlet and an indoor air outlet. For example, the indoor air inlet and indoor air outlet are disposed on a surface of the second housing. The indoor air outlet is located on the side of the second housing facing the indoor environment, allowing indoor air to enter the second housing through the indoor air inlet and then enter the indoor environment through the indoor air outlet.

[0043] It is understood that the first housing is disposed outdoors and is provided with an outdoor air inlet and an outdoor air outlet. Outdoor air enters the first housing through the outdoor air inlet and then exits the outdoors through the outdoor air outlet. The compressor, outdoor heat exchanger, and outdoor fan are disposed within the first housing. Outdoor air enters the first housing through the outdoor air inlet, undergoes heat exchange within the first housing, and is then discharged outdoors through the outdoor air outlet.

[0044] The second housing is disposed indoors, the first housing being connected to the second housing. The second housing is provided with an indoor air inlet and an indoor air outlet. Indoor air enters the second housing through the indoor air inlet and then enters the room through the indoor air outlet. The indoor heat exchanger and indoor fan are located within the second housing. Indoor air enters the second housing, exchanges heat at the indoor heat exchanger, and then enters the room through the indoor air outlet.

[0045] The compressor is housed within the first housing and is equipped with an exhaust port and a return port. The compressor compresses the refrigerant, converting the low-pressure refrigerant into a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor through the return port. The compressor compresses the low-pressure refrigerant into high-pressure refrigerant, which is then discharged through the exhaust port. The refrigerant releases heat in the condenser, then absorbs heat in the evaporator after decompression, before finally entering the compressor through the return port.

[0046] The outdoor heat exchanger is disposed within the first housing and exchanges heat between outdoor air and the refrigerant transported through the outdoor heat exchanger. Outdoor air entering the first housing through the outdoor air inlet flows through the outdoor heat exchanger to exchange heat with the refrigerant. Outdoor air enters the first housing through the outdoor air inlet and flows to the outdoor heat exchanger. The refrigerant then circulates within the outdoor heat exchanger, exchanging heat with the refrigerant as the outdoor air passes through the outdoor heat exchanger. The heat-exchanged outdoor air then flows to the outdoor air outlet and is discharged outdoors.

[0047] For example, in the air conditioner's cooling mode, the outdoor heat exchanger operates as a condenser, allowing the refrigerant compressed by the compressor to dissipate heat to the outdoor air through the outdoor heat exchanger, thereby condensing. In the air conditioner's heating mode, the outdoor heat exchanger operates as an evaporator, allowing the decompressed refrigerant to absorb heat from the outdoor air through the outdoor heat exchanger, thereby evaporating.

[0048] When the air conditioner is cooling, the exhaust port of the compressor is connected to the outdoor heat exchanger, which is a condenser. The outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger, where the refrigerant releases a large amount of heat; the outdoor air absorbs the heat of the refrigerant.

[0049] When the air conditioner is heating, the exhaust port of the compressor is connected to the indoor heat exchanger, and the outdoor heat exchanger is the evaporator. The refrigerant releases heat at the indoor heat exchanger and flows to the outdoor heat exchanger. The outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger, where the refrigerant absorbs heat from the outdoor air.

[0050] The outdoor fan is located in the first shell. Driven by the outdoor fan, outdoor air enters the first shell from the outdoor air inlet and flows to the outdoor heat exchanger. After the outdoor air exchanges heat with the refrigerant at the outdoor heat exchanger, the refrigerant is discharged to the outside from the outdoor air outlet under the drive of the outdoor fan.

[0051] The indoor heat exchanger is housed within the second housing and exchanges heat between indoor air and the refrigerant flowing through the indoor heat exchanger. Indoor air entering the second housing through the indoor air inlet flows through the indoor heat exchanger to exchange heat with the refrigerant. Indoor air enters the second housing through the indoor air inlet and flows to the indoor heat exchanger. The refrigerant then circulates within the indoor heat exchanger, exchanging heat with the refrigerant as the indoor air passes through the indoor heat exchanger. The heat-exchanged indoor air then flows to the indoor air outlet and is discharged into the room.

[0052] For example, in the air conditioner's cooling mode, the indoor heat exchanger operates as an evaporator, allowing the decompressed refrigerant to absorb heat from the indoor air through the indoor heat exchanger and evaporate. In the air conditioner's heating mode, the indoor heat exchanger operates as a condenser, allowing the refrigerant compressed by the compressor to dissipate heat to the indoor air through the indoor heat exchanger and condense.

[0053] When the air conditioner is cooling, the exhaust port of the compressor is connected to the outdoor heat exchanger, and the indoor heat exchanger is the evaporator. The refrigerant releases heat at the outdoor heat exchanger and flows to the indoor heat exchanger. The indoor air entering from the indoor air inlet flows to the indoor heat exchanger, and the refrigerant absorbs the heat of the indoor air at the indoor heat exchanger to achieve the effect of cooling the room.

[0054] When the air conditioner is heating, the exhaust port of the compressor is connected to the indoor heat exchanger, which is a condenser. The indoor air entering from the indoor air inlet flows to the indoor heat exchanger, where the refrigerant releases a large amount of heat; the indoor air absorbs the heat of the refrigerant, achieving the effect of heating the room.

[0055] The indoor fan is installed indoors. The rotation of the indoor fan drives airflow from the indoor air inlet into the second housing, where it exchanges heat with the indoor heat exchanger and then flows out of the indoor air outlet. The indoor fan is located within the second housing. Driven by the indoor fan, indoor air enters the second housing from the indoor air inlet and flows to the indoor heat exchanger. After the indoor air exchanges heat with the refrigerant at the indoor heat exchanger, the refrigerant is discharged into the room from the indoor air outlet driven by the indoor fan.

[0056] The fresh air component is arranged in the second shell, and the fresh air component includes: a fresh air volute and a fresh air fan. The fresh air fan rotates to drive the outdoor air into the fresh air volute and then into the room, realizing the circulation between the indoor air and the outdoor air and purifying the indoor air.

[0057] 5, 7, 10-13, the air conditioner further includes a drain pipe 33. During cooling, the indoor heat exchanger acts as an evaporator, and the refrigerant absorbs heat from the indoor air at the indoor heat exchanger, and the indoor air condenses into water, which is discharged outdoors through the drain pipe 33.

[0058] In some embodiments, the air conditioner further includes an electric wire conduit 34 connected between the indoor unit 10 and the outdoor unit.

[0059] As shown in Figures 4-11, the refrigerant circuit includes a first refrigerant pipe 31, which is connected between the compressor and the indoor heat exchanger. The first refrigerant pipe 31 is a gaseous refrigerant pipe. During heating, the indoor heat exchanger acts as a condenser, and the first refrigerant pipe 31 connects the compressor and the indoor heat exchanger. The high-temperature, high-pressure gaseous refrigerant discharged from the compressor flows through the first refrigerant pipe 31 to the indoor heat exchanger. During cooling, the indoor heat exchanger acts as an evaporator. The high-temperature, high-pressure gaseous refrigerant discharged from the compressor releases heat in the outdoor heat exchanger and becomes liquid refrigerant. The liquid refrigerant flows to the indoor heat exchanger, where it absorbs heat and becomes gaseous refrigerant. Finally, the gaseous refrigerant flows through the first refrigerant pipe 31 and returns to the compressor.

[0060] In some embodiments, the outer peripheral side of the first refrigerant tube 31 is covered with a first thermal insulation component 311. On the one hand, the first thermal insulation component 311 reduces the heat loss of the refrigerant flowing through the first refrigerant tube 31; on the other hand, the first thermal insulation component 311 protects the first refrigerant tube 31, which is beneficial to extending the service life of the first refrigerant tube 31.

[0061] The refrigerant circuit also includes a second refrigerant pipe 32, which connects the outdoor heat exchanger and the indoor heat exchanger. The second refrigerant pipe 32 is a liquid refrigerant pipe. During heating, the indoor heat exchanger acts as a condenser and the outdoor heat exchanger acts as an evaporator. High-temperature, high-pressure gaseous refrigerant is discharged from the compressor and flows through the first refrigerant pipe 31 to the indoor heat exchanger. There, the gaseous refrigerant exchanges heat with the indoor air flowing into the second shell. The gaseous refrigerant releases heat and turns into liquid refrigerant, completing indoor heating. The liquid refrigerant, which has released heat in the indoor heat exchanger, flows from the second refrigerant pipe 32 to the outdoor heat exchanger. The liquid refrigerant absorbs heat at the outdoor heat exchanger and turns into gaseous refrigerant. Finally, the gaseous refrigerant returns to the compressor.

[0062] In some embodiments, the outer circumference of the second refrigerant tube 32 is covered with a second insulation member 321. The second insulation member 321 reduces heat loss from the refrigerant flowing through the second refrigerant tube 32 and protects the second refrigerant tube 32, thereby extending the service life of the second refrigerant tube 32.

[0063] During cooling, the indoor heat exchanger serves as an evaporator and the outdoor heat exchanger serves as a condenser. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor flows to the indoor heat exchanger, where it exchanges heat and becomes liquid refrigerant. The liquid refrigerant flows from the outdoor heat exchanger through the second refrigerant pipe 32 to the indoor heat exchanger. The liquid refrigerant absorbs heat in the indoor heat exchanger and becomes gaseous refrigerant. Finally, the gaseous refrigerant flows from the indoor heat exchanger through the first refrigerant pipe 31 and returns to the compressor.

[0064] As shown in Figures 7 and 11 , the outer diameter of first refrigerant tube 31 is A, and the outer diameter of second refrigerant tube 32 is B. A and B satisfy the relationship: A > B. First refrigerant tube 31 is a gaseous refrigerant tube, and the refrigerant flowing through first refrigerant tube 31 is a gaseous refrigerant, while the refrigerant flowing through second refrigerant tube 32 is a liquid refrigerant. Therefore, the outer diameter of first refrigerant tube 31 is larger than the outer diameter of second refrigerant tube 32.

[0065] As shown in Figures 16 to 20, the air conditioner also includes: a fresh air duct, the fresh air duct includes: a wall-penetrating section 20 and an indoor section 40, the indoor section 40 is located on the indoor side, one side of the indoor section 40 is connected to the fresh air component, and the wall-penetrating section 20 is connected to the other side of the indoor section 40, that is, the indoor section 40 is connected between the fresh air component and the wall-penetrating section 20.

[0066] The wall-penetrating section 20 is disposed through the wall and includes an air inlet chamber 21. A first end of the air inlet chamber 21 communicates with the fresh air assembly, and a second end of the air inlet chamber 21 communicates with the outside. The air inlet chamber 21 connects both ends of the fresh air duct. The first end of the air inlet chamber 21 communicates with the outside, allowing outdoor air to enter the fresh air duct. A second end of the air inlet chamber 21 communicates with the indoor section 40, allowing outdoor air to pass through the wall-penetrating section 20 and the indoor section 40 and enter the fresh air assembly. From the fresh air assembly, it then enters the indoor room, purifying the indoor air.

[0067] As shown in Figures 1-11 , the wall-penetrating section 20 further includes a first accommodating chamber 22 having a first opening 26. The first accommodating chamber 22 is disposed adjacent to the air inlet chamber 21 and is configured to house a first refrigerant tube 31 and an electrical conduit 34. The first refrigerant tube 31 is disposed on the side of the electrical conduit 34 facing the first opening 26. The first accommodating chamber 22 connects the two ends of the wall-penetrating section 20. The first accommodating chamber 22 and the air inlet chamber 21 are disposed adjacent to each other, but are not connected to each other.

[0068] When installing the first refrigerant pipe 31, first place the wire pipe 34 inside the first accommodating cavity 22, then insert the first refrigerant pipe 31 into the first accommodating cavity 22 from the first opening 26, and the first refrigerant pipe 31 passes through the first accommodating cavity 22 to connect the indoor heat exchanger and the compressor.

[0069] The wall-penetrating section 20 also includes: a second accommodating chamber 23, the second accommodating chamber 23 is provided with a second opening 27, the second accommodating chamber 23 is arranged adjacent to the air inlet chamber 21, and the second accommodating chamber 23 is configured to place a second refrigerant pipe 32 and a drain pipe 33, and the second refrigerant pipe 32 is arranged on the side of the drain pipe 33 facing the second opening 27.

[0070] For example, the second accommodating chamber 23 communicates with both ends of the wall-penetrating section 20. The second accommodating chamber 23 is adjacent to the air inlet chamber 21, and the second accommodating chamber 23 is adjacent to the first accommodating chamber 22. The first accommodating chamber 22 and the second accommodating chamber 23 are not connected to the air inlet chamber 21. A drain pipe 33 is placed in the second accommodating chamber 23, and is located on the inner side of the second accommodating chamber 23 adjacent to the second opening 27. A second refrigerant pipe 32 is also placed in the second accommodating chamber 23, and is located on the outer side of the other end of the second accommodating chamber 23 adjacent to the second opening 27. The second refrigerant pipe 32 and the drain pipe 33 are spaced apart to prevent the drain pipe 33 from squeezing the second refrigerant pipe 32.

[0071] Some embodiments of the present disclosure are described with reference to FIG. 1 to FIG. 7 .

[0072] When the first accommodating chamber 22 and the second accommodating chamber 23 are connected to each other, the first accommodating chamber 22 and the second accommodating chamber 23 form a cavity, and the first refrigerant tube 31, the second refrigerant tube 32, the electric wire tube 34 and the drain pipe 33 are arranged in the cavity, and the electric wire tube 34 is located on the inner side of the first accommodating chamber 22, the first refrigerant tube 31 is also placed in the first accommodating chamber 22, the first refrigerant tube 31 is located on the outside of the first accommodating chamber 22, the first refrigerant tube 31 can be spaced apart from the electric wire tube 34 to avoid interference between the electric wire tube 34 and the first refrigerant tube 31; the drain pipe 33 is located on the inner side of the second accommodating chamber 23, the second refrigerant tube 32 is also placed in the second accommodating chamber 23, the second refrigerant tube 32 is located on the outside of the second accommodating chamber 23, the second refrigerant tube 32 and the drain pipe 33 are spaced apart to avoid the drain pipe 33 squeezing the second refrigerant tube 32.

[0073] The first thermal insulation component 311 and the second thermal insulation component 321 can be sponges, and the first refrigerant tube 31 and the second refrigerant tube 32 are arranged at intervals to prevent squeezing between the first thermal insulation component 311 and the second thermal insulation component 321 (i.e., sponges and sponges). This can reduce the space for laying pipes (i.e., the space of the accommodating cavity) and increase the space of the air inlet cavity 21.

[0074] Thus, by placing the first refrigerant tube 31 and the second refrigerant tube 32 adjacent to the first opening 26 and the second opening 27, it is possible to avoid the situation where the first opening 26 and the second opening 27 are located adjacent to the electrical conduit 34 or the drain pipe 33, and the electrical conduit 34 and the drain pipe 33 are not surrounded by sponge, which would cause difficulty in assembly. In addition, the sponge, as an expanding material, can be pressed against the first opening 26 and the second opening 27, utilizing the spare space at the first opening 26 and the second opening 27. This also facilitates the assembly of the wall penetration section 20 during the overall wall penetration process by manually pressing the sponge against the first opening 26 and the second opening 27, rather than having the drain pipe 33 and the electrical conduit 34 press against the sponge, which would be inconvenient to operate.

[0075] When the first accommodating chamber 22 and the second accommodating chamber 23 are connected to each other, the first opening 26 and the second opening 27 form a total opening 29. When installing the first refrigerant pipe 31 and the second refrigerant pipe 32, first place the drain pipe 33 and the electrical conduit 34 inside the accommodating chamber, respectively. Then, sequentially, the first refrigerant pipe 31 and the second refrigerant pipe 32 are placed into the first accommodating chamber 22 through the opening 29. The first refrigerant pipe 31 passes through the accommodating chamber to connect to the indoor heat exchanger and the compressor. The second refrigerant pipe 32 enters the accommodating chamber through the opening 29 and passes through the accommodating chamber to connect to the indoor heat exchanger and the outdoor heat exchanger.

[0076] The accommodating chamber and the air inlet chamber 21 are separated to reduce the large space occupancy rate caused by the disorderly arrangement of the pipelines, and the size of the air inlet chamber 21 is ensured as large as possible, thereby improving the fresh air volume and ventilation efficiency.

[0077] It should be noted that the air inlet chamber 21 and the accommodating chamber are configured to communicate with each other at both ends of the wall-penetrating section 20. That is, the air inlet chamber 21 and the accommodating chamber are the same length as the wall-penetrating section 20 and are arranged along the axial direction of the wall-penetrating section 20 to allow airflow through the air inlet chamber 21. The accommodating chamber is configured to accommodate the first refrigerant pipe 31 and the second refrigerant pipe 32, etc. The air inlet chamber 21 and the accommodating chamber are not connected to each other.

[0078] As shown in Figures 5 and 7, when the first accommodating chamber 22 and the second accommodating chamber 23 are connected to each other, the sum of the transverse dimensions of the first opening 26 and the second opening 27 is C, and A and C satisfy the relationship: A≤C≤A+6㎜. For example, the sum of the transverse dimensions of the first opening 26 and the second opening 27 is greater than the outer diameter of the first refrigerant tube 31. Since the outer diameter of the first refrigerant tube 31 is greater than the outer diameter of the second refrigerant tube 32, the sum of the transverse dimensions of the first opening 26 and the second opening 27 is greater than the outer diameter of the second refrigerant tube 32. The difference between the sum of the transverse dimensions of the first opening 26 and the second opening 27 and the outer diameter of the first refrigerant tube 31 is between 0-6㎜, leaving a size margin. When the first refrigerant tube 31 is coated with the first thermal insulation member 311, the first refrigerant tube 31 can also be placed in the first accommodating chamber 22 through the opening 29.

[0079] 8 to 11 , further embodiments of the present disclosure are described.

[0080] When the first accommodating chamber 22 and the second accommodating chamber 23 are not connected and are arranged adjacent to each other, the first accommodating chamber 22, the second accommodating chamber 23 and the air inlet chamber 21 are not connected to each other. The electric wire tube 34 is placed in the first accommodating chamber 22, and the electric wire tube 34 is located on the inner side of the first accommodating chamber 22 adjacent to the first opening 26. The first refrigerant tube 31 is also placed in the first accommodating chamber 22, and the first refrigerant tube 31 is located on the outer side of the first accommodating chamber 22 adjacent to the first opening 26. The first refrigerant tube 31 can be spaced apart from the electric wire tube 34 to avoid interference between the electric wire tube 34 and the first refrigerant tube 31. The second accommodating chamber 23 is connected to both ends of the wall-penetrating section 20, and the second accommodating chamber 23 and the air inlet chamber 21 are arranged adjacent to each other, and the second accommodating chamber 23 and the first accommodating chamber 22 are arranged adjacent to each other, and the first accommodating chamber 22, the second accommodating chamber 23 and the air inlet chamber 21 are not connected to each other. The second refrigerant pipe 32 enters the second accommodating chamber 23 from the second opening 27 , and passes through the second accommodating chamber 23 to communicate with the indoor heat exchanger and the outdoor heat exchanger.

[0081] The drain pipe 33 is placed in the second accommodating cavity 23, and the drain pipe 33 is located on the inner side of the second accommodating cavity 23 adjacent to the second opening 27. The second refrigerant pipe 32 is also placed in the second accommodating cavity 23, and the second refrigerant pipe 32 is located on the outer side of the other end of the second accommodating cavity 23 adjacent to the second opening 27. The second refrigerant pipe 32 and the drain pipe 33 are spaced apart to prevent the drain pipe 33 from squeezing the second refrigerant pipe 32.

[0082] When installing the second refrigerant pipe 32, first place the drain pipe 33 on the inner side of the first accommodating cavity 22, then insert the second refrigerant pipe 32 into the first accommodating cavity 22 from the second opening 27, and the second refrigerant pipe 32 passes through the first accommodating cavity 22 to connect the indoor heat exchanger and the outdoor heat exchanger.

[0083] The first accommodating chamber 22, the second accommodating chamber 23 and the air inlet chamber 21 are separated to reduce the large space occupancy rate caused by the cluttered arrangement of the pipelines, and to ensure the size of the air inlet chamber 21 as large as possible, thereby improving the fresh air volume and ventilation efficiency.

[0084] The outer wall of the wall-penetrating section 20 is discontinuous to form a first opening 26. The first accommodating cavity 22 is connected to the first opening 26. The first refrigerant pipe 31 is placed in the first accommodating cavity 22 through the first opening 26. Placing the first refrigerant pipe 31 in the first accommodating cavity 22 can prevent the first refrigerant pipe 31 from being unevenly arranged.

[0085] The outer wall of the through-wall section 20 is partially discontinuous to form a second opening 27. The second opening 27 is spaced apart from the first opening 26. The second accommodating chamber 23 is connected to the second opening 27. The second accommodating chamber 23 is adjacent to the first accommodating chamber 22. The second refrigerant pipe 32 enters the second accommodating chamber 23 through the second opening 27. The second refrigerant pipe 32 is placed in the second accommodating chamber 23, so that the second refrigerant pipe 32 is neatly routed. The first and second accommodating chambers 22 and 23 are provided within the fresh air duct, allowing other pipelines to be placed therein, thereby reducing the space occupied by the cluttered wiring of the individual pipelines and maximizing the fresh air volume and efficiency.

[0086] It should be noted that the air inlet chamber 21, the first accommodating chamber 22, and the second accommodating chamber 23 are configured to communicate with both ends of the air inlet pipe. That is, the air inlet chamber 21, the first accommodating chamber 22, and the second accommodating chamber 23 are the same length as the wall-penetrating section 20 and are arranged along the axial direction of the wall-penetrating section 20 to facilitate airflow through the air inlet chamber 21. The first accommodating chamber 22 is configured to accommodate the first refrigerant pipe 31, and the second accommodating chamber 23 is configured to accommodate the second refrigerant pipe 32. Furthermore, the air inlet chamber 21, the first accommodating chamber 22, and the second accommodating chamber 23 are not connected to each other.

[0087] Thus, the first refrigerant pipe 31 and the second refrigerant pipe 32 are placed in the first accommodating chamber 22 and the second accommodating chamber 23 of the wall-penetrating section 20, and the first accommodating chamber 22 and the second accommodating chamber 23 are separated from the air inlet chamber 21, thereby reducing the large space occupancy rate caused by the messy wiring of each pipeline, thereby improving the fresh air volume and fresh air efficiency; the wall-penetrating section 20 is set through the wall, and the operation is simple; the stability of the first refrigerant pipe 31 and the second refrigerant pipe 32 is ensured by utilizing the interference of the first thermal insulation component 311 and the second thermal insulation component 321 with the first opening 26 and the second opening 27.

[0088] As shown in Figure 11, the first accommodating chamber 22 and the second accommodating chamber 23 are not connected. The transverse dimension of the first opening 26 is D, and A and D satisfy the relationship: A≤D≤A+6㎜. In other words, the transverse dimension of the first opening 26 is larger than the outer diameter of the first refrigerant tube 31, and the difference between the transverse dimension of the first opening 26 and the outer diameter of the first refrigerant tube 31 is between 0-6㎜, and a size margin is reserved. When the first refrigerant tube 31 is coated with the first thermal insulation member 311, the first refrigerant tube 31 can also be placed in the first accommodating chamber 22 through the first opening 26.

[0089] In some embodiments, the transverse dimension of the second opening 27 is F, and B and F satisfy the relationship: B ≤ F ≤ B + 6 mm. In other words, the transverse dimension of the second opening 27 is larger than the outer diameter of the second refrigerant tube 32, and the difference between the transverse dimension of the second opening 27 and the outer diameter of the second refrigerant tube 32 is between 0 and 6 mm, leaving a dimensional margin. When the second refrigerant tube 32 is coated with the second thermal insulation member 321, the second refrigerant tube 32 can also be placed through the second opening 27 and into the second accommodating chamber 23.

[0090] In some embodiments, the transverse dimension of the first opening 26 is D, and the transverse dimension of the second opening 27 is F, where D and F satisfy the relationship: 2 mm ≤ DF ≤ 7 mm. The first refrigerant tube 31 is a gaseous refrigerant tube, and the refrigerant flowing through the first refrigerant tube 31 is a gaseous refrigerant, while the refrigerant flowing through the second refrigerant tube 32 is a liquid refrigerant. Therefore, the outer diameter of the first refrigerant tube 31 is larger than the outer diameter of the second refrigerant tube 32, and the transverse dimension of the first opening 26 is larger than the transverse dimension of the second opening 27.

[0091] Due to the size difference between the first refrigerant tube 31 and the second refrigerant tube 32, the difference between the lateral size of the first opening 26 and the lateral size of the second opening 27 is between 2mm and 7mm, so that the first refrigerant tube 31 can enter the first accommodating chamber 22 from the first opening 26, and the second refrigerant tube 32 can enter the second accommodating chamber 23 from the second opening 27.

[0092] In the above embodiment, the wall-penetrating section 20 includes a first tube body 24 having an arc-shaped structure and having a first opening 26 and a second opening 27 formed therein. The first tube body 24 having an arc-shaped structure is a discontinuous structure, that is, the first tube body 24 is a non-closed structure, and has the first opening 26 and the second opening 27 formed therein.

[0093] In some embodiments, when the first accommodating cavity 22 and the second accommodating cavity 23 are connected, the first refrigerant tube 31 and the second refrigerant tube 32 pass through the opening 29 formed by the first opening 26 and the second opening 27 and are placed in the first accommodating cavity 22 and the second accommodating cavity 23 .

[0094] In some embodiments, the first refrigerant tube 31 is placed in the first accommodating chamber 22 through the first opening 26 ; and a second opening 27 is formed on the first tube body 24 , and the second refrigerant tube 32 is placed in the second accommodating chamber 23 through the second opening 27 .

[0095] Referring to Figures 1 to 11, in some embodiments, the wall-penetrating section 20 also includes: a second tube body 25, which is connected to the inner wall of the first tube body 24, and one side of the second tube body 25 forms a first accommodating cavity 22 and a second accommodating cavity 23 with the first tube body 24, and the other side of the second tube body 25 forms a closed air inlet cavity 21 with the first tube body 24.

[0096] For example, the first tube body 24 and the second tube body 25 extend axially along the wall-penetrating section 20. The second tube body 25 is disposed within the first tube body 24 and connected to the inner wall of the first tube body 24. The second tube body 25 divides the first tube body 24 to form an air inlet cavity 21, a first accommodating cavity 22, and a second accommodating cavity 23 within the first tube body 24.

[0097] The side of the second tube body 25 facing the first opening 26 and the second opening 27 forms the first accommodating cavity 22 and the second accommodating cavity 23 with a portion of the first tube body 24. The first refrigerant tube 31, the second refrigerant tube 32, the electric wire tube 34 and the drain pipe 33 are placed in the first accommodating cavity 22 and the second accommodating cavity 23 through the first opening 26 and the second opening 27, so that the first refrigerant tube 31, the second refrigerant tube 32, the electric wire tube 34 and the drain pipe 33 are arranged neatly.

[0098] The other side of the second tube body 25 and another part of the first tube body 24 form a closed air inlet chamber 21, which connects the outdoors and the fresh air component, thereby introducing fresh air from the outdoors into the fresh air component and entering the room under the operation of the fresh air component to purify the indoor air.

[0099] As shown in FIG2 , in some embodiments, the second tube body 25 includes a plurality of arcuate segments 251 connected to one another and disposed opposite the first opening 26 and the second opening 27. The plurality of arcuate segments 251 are recessed toward a side facing away from the first opening 26 and the second opening 27. The second tube body 25 includes a plurality of arcuate segments 251 connected in sequence, the arcuate segments 251 being recessed toward the first opening 26 and the second opening 27. An arcuate receiving portion is formed in each of the arcuate segments 251. One of the arcuate segments 251 is connected to the inner wall of one side of the first tube body 24 and can be configured to receive the drain pipe 33. Another of the arcuate segments 251 is connected to the inner wall of the other side of the first tube body 24 and can be configured to receive the electrical conduit 34. The plurality of arc segments 251 are sequentially connected to form a plurality of accommodating portions configured to accommodate the first refrigerant pipe 31 , the second refrigerant pipe 32 , the drain pipe 33 and the electric wire pipe 34 .

[0100] In yet other embodiments, the wall-penetrating segment 20 includes two second tubes 25. One side of one of the two second tubes 25 and a portion of the first tube 24 form a first accommodating cavity 22. One side of the other of the two second tubes 25 and another portion of the first tube 24 form a second accommodating cavity 23. The first accommodating cavity 22 and the second accommodating cavity 23 are spaced apart and disconnected from each other along the axial direction of the wall-penetrating segment 20. The other side of one of the second tubes 25 and the other side of the other second tube 25, together with another portion of the first tube 24, form a circumferentially closed air inlet cavity 21. The air inlet cavity 21 is disconnected from the first accommodating cavity 22 and the second accommodating cavity 23.

[0101] As shown in FIG9 , in other embodiments, when the first accommodating chamber 22 and the second accommodating chamber 23 are not connected and are disposed adjacent to each other, the wall-penetrating section 20 further includes a third tube 28, the first end of the third tube 28 being connected to the second tube 25, and the second end of the third tube 28 extending to the first opening 26 and the second opening 27 to separate the first accommodating chamber 22 and the second accommodating chamber 23. In other words, the third tube 28 separates the first accommodating chamber 22 and the second accommodating chamber 23, so that the first accommodating chamber 22 and the second accommodating chamber 23 are not connected to each other, the first refrigerant pipe 31 and the electrical conduit 34 enter the first accommodating chamber 22 through the first opening 26, and the second refrigerant pipe 32 and the drain pipe 33 enter the second accommodating chamber 23 through the second opening 27.

[0102] As shown in Figures 7 and 9, at least one end of the first opening 26 is provided with a first inverted tooth 241, which is located on the side of the first tube 24 facing the center. The structure of the first tube 24 is discontinuous to form the first opening 26, and at least one end of the first opening 26 is provided with a first inverted tooth 241, which is located on the side of the first tube 24 facing the center. The first inverted tooth 241 is provided on the outer wall of the first tube 24, and is located on the side of the first tube 24 facing the center. The first inverted tooth 241 can increase the friction between the first tube 24 and the first refrigerant tube 31, thereby preventing the first refrigerant tube 31 from ejecting from the third opening 29.

[0103] At least one end of the second opening 27 is provided with a second inverted tooth 242, located on the side of the first tube 24 facing the center. The first tube 24 is discontinuous in structure to form the second opening 27. At least one end of the second opening 27 is provided with a second inverted tooth 242, located on the side of the first tube 24 facing the center of the fresh air duct. The second inverted tooth 242 is provided on the first tube 24, located on the side of the first tube 24 facing the center. This increases friction between the first tube 24 and the second refrigerant tube 32, preventing the second refrigerant tube 32 from ejecting from the third opening 29.

[0104] The first thermal insulation component 311 and the second thermal insulation component 321 can be sponges, and the first refrigerant tube 31 and the second refrigerant tube 32 are arranged separately to prevent the first thermal insulation component 311 and the second thermal insulation component 321 (i.e., sponges and sponges) from being squeezed. The first thermal insulation component 311 can prevent the squeezing of the wire tube 34 and the drain pipe 33, and the second thermal insulation component 321 makes the first refrigerant tube 31 fit tightly with the second accommodating chamber 23, which can reduce the space for pipe layout (i.e., the space of the first accommodating chamber 22) and increase the space of the air inlet chamber 21.

[0105] Thus, by placing the first refrigerant pipe 31 against the side of the first opening 26, it is possible to avoid the problem of the first opening 26 being occupied by the electrical conduit 34 or the drain pipe 33 when the first opening 26 is installed inwardly, as there is no sponge around the electrical conduit 34 and the drain pipe 33, which would make assembly difficult. In addition, the sponge, as an expanding material, can be pressed against the first opening 26, utilizing the spare space at the first opening 26. This also facilitates the assembly of the wall-penetrating section 20 during the entire wall penetration process by manually pressing the sponge against the first opening 26, rather than the drain pipe 33 or the electrical conduit 34 pressing the sponge, which would be inconvenient.

[0106] By placing the second refrigerant pipe 32 against the side of the second opening 27, the sponge, as an expanding material property, can be pushed against the second opening 27, and the remaining space at the second opening 27 is utilized. It is also convenient for the wall-penetrating section 20 to be assembled during the overall wall-penetrating process by manually pressing the sponge against the second opening 27.

[0107] Thus, the first refrigerant tube 31 and the second refrigerant tube 32 are placed in the first accommodating chamber 22 and the second accommodating chamber 23 respectively, and the first accommodating chamber 22 and the second accommodating chamber 23 are separated from the air inlet chamber 21, reducing the large space occupancy rate caused by the messy wiring of each pipeline, thereby improving the fresh air volume and fresh air efficiency; the wall-penetrating section 20 is set through the wall, and the operation is simple; the first opening 26 does not need to be provided with a cover, and a first inverted tooth 241 is provided at at least one end of the first opening 26, and the inverted tooth can prevent the first refrigerant tube 31 from popping out.

[0108] The second opening 27 does not need to be covered. A second inverted tooth 242 is provided at at least one end of the second opening 27 . The inverted tooth 242 can prevent the second refrigerant tube 32 from popping out.

[0109] As shown in Figures 16-20 , the indoor section 40 further includes a connecting pipe, the air inlet end of which is connected to the air outlet end of the air inlet chamber 21 , and the air outlet end of which is connected to the air inlet of the fresh air assembly. The air inlet end of the connecting pipe is connected to the air outlet end of the air inlet chamber 21 by adhesive, and the air outlet end of the connecting pipe is connected to the air inlet of the fresh air assembly by threads.

[0110] The connecting pipe includes a first section and a second section. The first end of the first section is connected to the air inlet of the fresh air component, the first end of the second section is connected to the second end of the first section, and the second end of the second section is connected to the air outlet of the air inlet chamber 21. The first section and the second section are connected to each other. The first section is provided on the side where the connecting pipe is connected to the fresh air component, and the second section is provided on the side where the connecting pipe is connected to the air inlet chamber 21. The first section is hollow inside and is connected to the air inlet of the fresh air component. The second section is hollow inside and is connected to the air inlet chamber 21. The first section and the second section are connected so that the connecting pipe connects the fresh air component and the air inlet chamber 21, so that outdoor air enters the air inlet chamber 21 and enters the fresh air component along the connecting pipe.

[0111] The cross-sectional shape of the second section is consistent with the cross-sectional shape of the air inlet cavity 21 , and the first section is adapted to the air inlet cavity 21 , so that the air outlet end of the first section and the air inlet cavity 21 are tightly connected, avoiding air leakage at the connection between the first section and the air inlet cavity 21 .

[0112] Some further embodiments of the present disclosure are described with reference to FIG. 12 to FIG. 15 and FIG. 20 .

[0113] The air conditioner includes: a refrigerant circuit, in which the refrigerant circulates sequentially through a compressor, a condenser, a pressure reducer and an evaporator, one of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger; an outdoor unit, located on the outdoor side, the outdoor unit includes a first shell and an outdoor fan, a compressor and an outdoor heat exchanger arranged in the first shell; an indoor unit 10, located on the indoor side, the indoor unit 10 includes a second shell and an indoor fan, an indoor heat exchanger and a fresh air component arranged in the second shell.

[0114] As shown in Figures 12 and 13, the air conditioner further includes a drain pipe 33. During cooling, the indoor heat exchanger acts as an evaporator, and the refrigerant absorbs heat from the indoor air at the indoor heat exchanger, and the indoor air condenses into water, which is discharged outdoors through the drain pipe 33.

[0115] The air conditioner also includes: a fresh air duct, which includes: a wall-penetrating section 20 and an indoor section 40, the indoor section 40 is located on the indoor side, one side of the indoor section 40 is connected to the fresh air component, and the wall-penetrating section 20 is connected to the other side of the indoor section 40, that is, the indoor section 40 is connected between the fresh air component and the wall-penetrating section 20.

[0116] As shown in Figures 13-15 and 20 , the wall-penetrating section 20 is installed through the wall and includes an air inlet chamber 21. The first end of the air inlet chamber 21 is connected to the fresh air assembly, and the second end of the air inlet chamber 21 is connected to the outside. The air inlet chamber 21 connects both ends of the fresh air duct. The first end of the air inlet chamber 21 is connected to the outside, allowing outdoor air to enter the fresh air duct. The second end of the air inlet chamber 21 is connected to the indoor section 40, allowing outdoor air to pass through the wall-penetrating section 20 and the indoor section 40 and enter the fresh air assembly. From the fresh air assembly, it enters the indoor room to purify the indoor air.

[0117] As shown in Figures 13-15 , the through-wall section 20 further includes a first accommodating chamber 22 having a first opening 26. The first accommodating chamber 22 is disposed adjacent to the air inlet chamber 21 but not in communication therewith, and is configured to house a first refrigerant pipe 31, an electrical conduit 34, and a drain pipe 33. The first refrigerant pipe 31 is disposed on the side of the electrical conduit 34 and drain pipe 33 that faces the first opening 26. The first accommodating chamber 22 connects both ends of the through-wall section 20 and is disposed adjacent to the air inlet chamber 21 but not in communication therewith. The wire conduit 34 and the drain pipe 33 are placed in the first accommodating cavity 22, and the wire conduit 34 and the drain pipe 33 are located on the inner side of the first accommodating cavity 22 adjacent to the first opening 26. The first refrigerant pipe 31 is also placed in the first accommodating cavity 22, and the first refrigerant pipe 31 is located on the outer side of the first accommodating cavity 22 adjacent to the first opening 26. The first refrigerant pipe 31 can be spaced apart from the wire conduit 34 and the drain pipe 33 to avoid interference between the wire conduit 34 and the drain pipe 33 and the first refrigerant pipe 31.

[0118] When installing the first refrigerant pipe 31, first place the wire pipe 34 and the drain pipe 33 on the inner side of the first accommodating chamber 22, then insert the first refrigerant pipe 31 into the first accommodating chamber 22 from the first opening 26, and the first refrigerant pipe 31 passes through the first accommodating chamber 22 to connect the indoor heat exchanger and the compressor.

[0119] The through-wall section 20 further includes a second accommodating chamber 23 having a second opening 27. The second accommodating chamber 23 is disposed adjacent to the air inlet chamber 21 and spaced apart from the first accommodating chamber 22 in the circumferential direction of the through-wall section 20. The second accommodating chamber 23 is configured to house a second refrigerant pipe 32. The second accommodating chamber 23 communicates with both ends of the through-wall section 20. The second accommodating chamber 23 is disposed adjacent to the air inlet chamber 21, and the second accommodating chamber 23 and the first accommodating chamber 22 are spaced apart in the circumferential direction of the through-wall section 20. The second accommodating chamber 23 and the first accommodating chamber 22 are not connected. The second refrigerant pipe 32 enters the second accommodating chamber 23 through the second opening 27 and passes through the second accommodating chamber 23 to connect the indoor heat exchanger with the outdoor heat exchanger.

[0120] The first accommodating chamber 22, the second accommodating chamber 23 and the air inlet chamber 21 are separated to reduce the large space occupancy rate caused by the cluttered arrangement of the pipelines, and to ensure the size of the air inlet chamber 21 as large as possible, thereby improving the fresh air volume and ventilation efficiency.

[0122] The first tube body 24 is partially discontinuous to form a second opening 27. The second opening 27 is spaced apart from the first opening 26. The second accommodating chamber 23 is connected to the second opening 27. The second accommodating chamber 23 is adjacent to the first accommodating chamber 22. The second refrigerant pipe 32 enters the second accommodating chamber 23 from the second opening 27. The second refrigerant pipe 32 is placed in the second accommodating chamber 23, so that the second refrigerant pipe 32 is neatly arranged. The first accommodating chamber 22 and the second accommodating chamber 23 are provided in the wall-penetrating section 20, and other pipelines can be placed therein, thereby reducing the space occupied by the disorderly arrangement of the individual pipelines and maximizing the fresh air volume and fresh air efficiency.

[0123] It should be noted that the air inlet chamber 21, the first accommodating chamber 22 and the second accommodating chamber 23 are configured to connect the two ends of the air inlet pipe, that is, the air inlet chamber 21, the first accommodating chamber 22 and the second accommodating chamber 23 are the same length as the air inlet pipe and are arranged along the axial direction of the air inlet pipe.

[0124] Therefore, the first refrigerant pipe 31, the drainage pipe 33 and the electric wire pipe 34 are arranged in the first accommodating chamber 22, and the second refrigerant pipe 32 is arranged in the second accommodating chamber 23. The first accommodating chamber 22, the second accommodating chamber 23 and the air inlet chamber 21 are separated, thereby reducing the large space occupancy rate caused by the messy wiring of each pipeline, thereby improving the fresh air volume and fresh air efficiency; the wall-penetrating section 20 is set through the wall, and the operation is simple.

[0125] Those skilled in the art will understand that the scope of the present disclosure is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application.
