[0044] Embodiments of the present application are described in detail below with reference to the accompanying drawings. Embodiments of the present application are described in detail below.

[0045] Reference is made to Figures 1-20 An air conditioner according to embodiments of the present application is described below.

[0046] With reference to Figures 16-20 shown, the air conditioner includes a refrigerant circuit, an outdoor unit part, and an indoor unit part 10.

[0047] In the refrigerant circuit, refrigerant circulates through a compressor, a condenser, a pressure reducer, and an evaporator in this order, one of the condenser and the evaporator is an outdoor heat exchanger, and the other is an indoor heat exchanger. The outdoor unit part is located on an outdoor side, and includes a first housing, and an outdoor fan, the compressor, and the outdoor heat exchanger provided in the first housing.

[0048] The first shell is formed with an outdoor air inlet and an outdoor air outlet, i.e., the first shell surface is arranged at the outdoor air inlet and the outdoor air outlet. The outdoor air outlet is located at the side of the first shell facing the outdoor, so that the outdoor air enters the first shell from the outdoor air inlet and then enters the outdoor from the outdoor air outlet.

[0049] The indoor unit 10 is located at the indoor side, and the indoor unit 10 includes a second shell and an indoor fan, an indoor heat exchanger and a fresh air module arranged in the second shell. The second shell is formed with an indoor air inlet and an indoor air outlet, i.e., the second shell surface is arranged at the indoor air inlet and the indoor air outlet. The indoor air outlet is located at the side of the second shell facing the indoor, so that the indoor air enters the second shell from the indoor air inlet and then enters the indoor from the indoor air outlet.

[0050] It can be understood that the first shell is arranged at the outdoor, i.e., the first shell is provided with the outdoor air inlet and the outdoor air outlet, and the outdoor air enters the first shell from the outdoor air inlet and then enters the outdoor from the outdoor air outlet. The compressor, the outdoor heat exchanger and the outdoor fan are arranged in the first shell, and the outdoor air enters the first shell from the outdoor air inlet and is discharged to the outdoor from the outdoor air outlet after heat exchange in the first shell.

[0051] The second shell is arranged at the indoor, and the first shell and the second shell are connected, i.e., the second shell is provided with the indoor air inlet and the indoor air outlet, and the indoor air enters the second shell from the indoor air inlet and then enters the indoor from the indoor air outlet. The indoor heat exchanger and the indoor fan are located in the second shell, and the indoor air enters the second shell, exchanges heat at the indoor heat exchanger and then enters the indoor from the indoor air outlet.

[0052] The compressor is arranged in the first shell, and the compressor is provided with a discharge port and a return port. The compressor compresses the refrigerant, so that the low-pressure refrigerant becomes high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor from the return port, and the high-pressure refrigerant is discharged from the discharge port after being compressed by the compressor. The refrigerant releases heat at the condenser, absorbs heat after being decompressed at the evaporator, and finally enters the compressor from the return port.

[0053] The outdoor heat exchanger is arranged in the first shell, and the outdoor heat exchanger exchanges heat between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger. The outdoor air entering the first shell from the outdoor air inlet flows to the outdoor heat exchanger to exchange heat with the refrigerant. The outdoor air enters the first shell from the outdoor air inlet and flows to the outdoor heat exchanger, and the refrigerant flows in the outdoor heat exchanger. When the outdoor air passes through the outdoor heat exchanger, the outdoor air exchanges heat with the refrigerant. The heat-exchanged outdoor air then flows to the outdoor air outlet and is discharged to the outdoor from the outdoor air outlet.

[0054] For example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor releases heat to the outdoor air through the outdoor heat exchanger and is condensed. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the refrigerant after decompression absorbs heat of the outdoor air through the outdoor heat exchanger and is evaporated.

[0055] When the air conditioner is cooling, the discharge port of the compressor is communicated with the outdoor heat exchanger, the outdoor heat exchanger is a condenser, the outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger, and the refrigerant releases a large amount of heat at the outdoor heat exchanger; the outdoor air absorbs the heat of the refrigerant.

[0056] When the air conditioner is heating, the discharge port of the compressor is communicated with the indoor heat exchanger, the outdoor heat exchanger is an evaporator, and the refrigerant releases heat at the indoor heat exchanger and then flows to the outdoor heat exchanger. The outdoor air entering from the outdoor air inlet flows to the outdoor heat exchanger, and the refrigerant absorbs heat of the outdoor air at the outdoor heat exchanger.

[0057] The outdoor fan is located in the first shell, and under the driving of the outdoor fan, the outdoor air enters the first shell from the outdoor air inlet, flows to the outdoor heat exchanger, and the refrigerant is discharged to the outdoor from the outdoor air outlet under the driving of the outdoor fan after heat exchange with the refrigerant at the outdoor heat exchanger.

[0058] The indoor heat exchanger is arranged in the second shell and exchanges heat between the indoor air and the refrigerant transmitted in the indoor heat exchanger. The indoor air entering the second shell from the indoor air inlet flows to the indoor heat exchanger and exchanges heat with the refrigerant. The indoor air enters the second shell from the indoor air inlet, flows to the indoor heat exchanger, and the indoor air exchanges heat with the refrigerant when passing through the indoor heat exchanger; the indoor air after heat exchange flows to the indoor air outlet and is discharged to the indoor from the indoor air outlet.

[0059] For example, the indoor heat exchanger works as an evaporator in the cooling mode of the air conditioner, so that the refrigerant after decompression absorbs heat of the indoor air through the indoor heat exchanger and is evaporated. The indoor heat exchanger works as a condenser in the heating mode of the air conditioner, so that the refrigerant compressed by the compressor releases heat to the indoor air through the indoor heat exchanger and is condensed.

[0060] When the air conditioner is cooling, the discharge port of the compressor is communicated with the outdoor heat exchanger, the indoor heat exchanger is an evaporator, the refrigerant releases heat at the outdoor heat exchanger and then 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 heat of the indoor air at the indoor heat exchanger to achieve the effect of cooling the indoor.

[0061] 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.

[0062] 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.

[0063] The fresh air module is arranged in the second shell, and the fresh air module 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, thereby realizing the circulation between the indoor air and the outdoor air and purifying the indoor air.

[0064] Reference Figure 5 、 Figure 7 、 Figures 10-13 As shown, the air conditioner further includes a drain pipe 33. During cooling, the indoor heat exchanger acts as an evaporator, 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.

[0065] Furthermore, the air conditioner further includes an electric wire conduit 34 connected between the indoor unit 10 and the outdoor unit.

[0066] like Figures 4-11 As shown, 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.

[0067] 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 and extends the service life of the first refrigerant tube 31.

[0068] 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.

[0069] 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 its service life.

[0070] 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.

[0071] like Figure 7 and Figure 11 As shown, the outer diameter of the first refrigerant tube 31 is A, and the outer diameter of the second refrigerant tube 32 is B. A and B satisfy the relationship: A>B. The first refrigerant tube 31 is a gaseous refrigerant tube. 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.

[0072] like Figures 16-20 As shown, the air conditioner also includes: a fresh air duct, the fresh air duct includes: a through-wall 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 module, and the through-wall 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 module and the through-wall section 20.

[0073] The wall-penetrating section 20 is arranged to penetrate the wall, and the wall-penetrating section 20 comprises: an air inlet cavity 21, one end of the air inlet cavity 21 being in communication with the fresh air module and the other end being in communication with the outdoor environment. The air inlet cavity 21 is in communication with both ends of the fresh air pipe, one end of the air inlet cavity 21 being in communication with the outdoor environment so that outdoor air can enter the fresh air pipe, and the other end of the air inlet cavity 21 being in communication with the indoor section 40 so that outdoor air can enter the fresh air module through the wall-penetrating section 20 and the indoor section 40 and then enter the indoor environment to purify the indoor air.

[0074] In combination Figures 1-11 As shown, the wall-penetrating section 20 further comprises: a first accommodating cavity 22, the first accommodating cavity 22 being provided with a first opening 26, the first accommodating cavity 22 being arranged adjacent to the air inlet cavity 21 and being used for placing the first refrigerant pipe 31 and the electric wire pipe 34, the first refrigerant pipe 31 being arranged on the side of the electric wire pipe 34 facing the first opening 26. The first accommodating cavity 22 is in communication with both ends of the wall-penetrating section 20, the first accommodating cavity 22 and the air inlet cavity 21 are arranged adjacent to each other, and the first accommodating cavity 22 and the air inlet cavity 21 are not in communication with each other.

[0075] When the first refrigerant pipe 31 is installed, the electric wire pipe 34 is first placed inside the first accommodating cavity 22, then the first refrigerant pipe 31 is arranged in the first accommodating cavity 22 from the first opening 26, and the first refrigerant pipe 31 passes through the first accommodating cavity 22 to be in communication with the indoor heat exchanger and the compressor.

[0076] The wall-penetrating section 20 further comprises: a second accommodating cavity 23, the second accommodating cavity 23 being provided with a second opening 27, the second accommodating cavity 23 being arranged adjacent to the air inlet cavity 21, the second accommodating cavity 23 being used for placing the second refrigerant pipe 32 and the drain pipe 33, the second refrigerant pipe 32 being arranged on the side of the drain pipe 33 facing the second opening 27. Specifically, the second accommodating cavity 23 is in communication with both ends of the wall-penetrating section 20, the second accommodating cavity 23 and the air inlet cavity 21 are arranged adjacent to each other, and the second accommodating cavity 23 and the first accommodating cavity 22 are arranged adjacent to each other, the first accommodating cavity 22 and the second accommodating cavity 23 are both not in communication with the air inlet cavity 21. The drain pipe 33 is placed inside the second accommodating cavity 23, the drain pipe 33 being located on the inner side of the second accommodating cavity 23 close to the second opening 27, the second refrigerant pipe 32 is also placed inside the second accommodating cavity 23, the second refrigerant pipe 32 being located on the outer side of the second accommodating cavity 23 close to the other end of the second opening 27, the second refrigerant pipe 32 is arranged in a spaced manner with the drain pipe 33 to avoid the drain pipe 33 pressing the second refrigerant pipe 32.

[0077] In combination Figures 1-7 As shown, the embodiment one of the present application is described as follows:

[0078] When the first accommodating cavity 22 and the second accommodating cavity 23 are communicated with each other, the first accommodating cavity 22 and the second accommodating cavity 23 form a cavity, the first refrigerant pipe 31, the second refrigerant pipe 32, the electric wire pipe 34 and the drain pipe 33 are arranged in the cavity, and the electric wire pipe 34 is located at the inner side of the first accommodating cavity 22, the first refrigerant pipe 31 is also arranged in the first accommodating cavity 22, the first refrigerant pipe 31 is located at the outer side of the first accommodating cavity 22, the first refrigerant pipe 31 can be arranged separately from the electric wire pipe 34 to avoid interference between the electric wire pipe 34 and the first refrigerant pipe 31; the drain pipe 33 is located at the inner side of the second accommodating cavity 23, the second refrigerant pipe 32 is also arranged in the second accommodating cavity 23, the second refrigerant pipe 32 is located at the outer side of the second accommodating cavity 23, and the second refrigerant pipe 32 is arranged separately from the drain pipe 33 to avoid extrusion of the second refrigerant pipe 32 by the drain pipe 33.

[0079] The first heat preservation member 311 and the second heat preservation member 321 can be sponges, the first refrigerant pipe 31 and the second refrigerant pipe 32 are arranged separately to prevent extrusion between the first heat preservation member 311 and the second heat preservation member 321 (i.e. between the sponges and the sponges), so that the space for arranging the pipes can be reduced and the space of the air inlet cavity 21 can be increased.

[0080] By arranging the first refrigerant pipe 31 and the second refrigerant pipe 32 close to the first opening 26 and the second opening 27, the first opening 26 and the second opening 27 are not arranged at the electric wire pipe 34 or the drain pipe 33 when arranged inward, the outer periphery of the electric wire pipe 34 and the drain pipe 33 is not provided with a sponge, and there is a problem of poor assembly; meanwhile, the sponge is an expanded material, and can be pressed at the first opening 26 and the second opening 27, and the excess space at the first opening 26 and the second opening 27 can also be utilized, so that the wall-penetrating section 20 can be conveniently assembled by pressing the sponge at the first opening 26 and the second opening 27 during the overall wall-penetrating process, instead of pressing the sponge by the drain pipe 33 and the electric wire pipe 34, and the operation is simple.

[0081] When the first accommodating cavity 22 and the second accommodating cavity 23 are communicated with each other, the first opening 26 and the second opening 27 form a total opening 29. When the first refrigerant pipe 31 and the second refrigerant pipe 32 are installed, the drain pipe 33 and the electric wire pipe 34 are arranged at the inner side of the accommodating cavity, and then the first refrigerant pipe 31 and the second refrigerant pipe 32 are arranged in the first accommodating cavity 22 from the opening 29, the first refrigerant pipe 31 passes through the accommodating cavity to connect the indoor heat exchanger and the compressor, and the second refrigerant pipe 32 passes through the opening 29 into the accommodating cavity, and the second refrigerant pipe 32 passes through the accommodating cavity to connect the indoor heat exchanger and the outdoor heat exchanger.

[0082] The accommodating cavity and the air inlet cavity 21 are separated to reduce the space occupation rate caused by the disordered arrangement of the pipes, to ensure the size of the air inlet cavity 21 as much as possible, and to improve the fresh air volume and the air exchange efficiency.

[0083] It should be noted that: the air inlet cavity 21 and the containing cavity are both configured to communicate with both ends of the through-wall section 20, that is, the air inlet cavity 21 and the containing cavity are both arranged along the axial direction of the through-wall section 20 and have the same length as the through-wall section 20, so that the air inlet cavity 21 flows air, and the containing cavity is used to arrange the first refrigerant pipe 31 and the second refrigerant pipe 32. The air inlet cavity 21 and the containing cavity are not communicated with each other.

[0084] As shown in Figure 5 and Figure 7 , when the first containing cavity 22 and the second containing cavity 23 are communicated with 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+6mm. Specifically, 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 pipe 31, and since the outer diameter of the first refrigerant pipe 31 is greater than the outer diameter of the second refrigerant pipe 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 pipe 32, and 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 pipe 31 is between 0-6mm, leaving a certain size allowance, and when the first refrigerant pipe 31 is covered with the first heat preservation member 311, the first refrigerant pipe 31 can also be placed in the first containing cavity 22 through the opening 29.

[0085] As shown in Figures 8-11 , the second embodiment of the present application is described as follows:

[0086] When the first containing cavity 22 and the second containing cavity 23 are not communicated and arranged adjacent to each other, the first containing cavity 22, the second containing cavity 23 and the air inlet cavity 21 are not communicated with each other. The wire pipe 34 is placed in the first containing cavity 22, and the wire pipe 34 is located on the inner side of the first containing cavity 22 close to the first opening 26, and the first refrigerant pipe 31 is also placed in the first containing cavity 22, and the first refrigerant pipe 31 is located on the outer side of the first containing cavity 22 close to the first opening 26, and the first refrigerant pipe 31 can be arranged separately from the wire pipe 34 to avoid interference between the wire pipe 34 and the first refrigerant pipe 31. The second containing cavity 23 communicates with both ends of the through-wall section 20, the second containing cavity 23 and the air inlet cavity 21 are arranged adjacent to each other, and the second containing cavity 23 and the first containing cavity 22 are arranged adjacent to each other, and the first containing cavity 22, the second containing cavity 23 and the air inlet cavity 21 are not communicated with each other. The second refrigerant pipe 32 enters the second containing cavity 23 from the second opening 27, and the second refrigerant pipe 32 communicates the indoor heat exchanger and the outdoor heat exchanger through the second containing cavity 23.

[0087] The drain pipe 33 is placed in the second accommodating cavity 23, and the drain pipe 33 is located at the inner side of the second accommodating cavity 23 close 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 at the outer side of the second accommodating cavity 23 close to the other end of the second opening 27. The second refrigerant pipe 32 is arranged in a spaced manner with the drain pipe 33 to avoid the drain pipe 33 from pressing the second refrigerant pipe 32.

[0088] When the second refrigerant pipe 32 is installed, the drain pipe 33 is first placed at the inner side of the first accommodating cavity 22, and then the second refrigerant pipe 32 is placed in 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.

[0089] The first accommodating cavity 22, the second accommodating cavity 23, and the air inlet cavity 21 are separated to reduce the large space occupancy rate caused by the disordered arrangement of various pipelines, and the size of the air inlet cavity 21 is as large as possible, thereby improving the fresh air volume and the ventilation efficiency.

[0090] The outer wall of the wall-penetrating section 20 is discontinuous to form the first opening 26. The first accommodating cavity 22 is in communication with the first opening 26. The first refrigerant pipe 31 is placed in the first accommodating cavity 22 through the first opening 26. The first refrigerant pipe 31 is placed in the first accommodating cavity 22 to prevent the first refrigerant pipe 31 from being disordered.

[0091] The outer wall of the wall-penetrating section 20 is partially discontinuous to form the second opening 27. The second opening 27 is arranged in a spaced manner with the first opening 26. The second accommodating cavity 23 is in communication with the second opening 27. The second accommodating cavity 23 is arranged adjacent to the first accommodating cavity 22. The second refrigerant pipe 32 is placed in the second accommodating cavity 23 from the second opening 27. The second refrigerant pipe 32 is placed in the second accommodating cavity 23 to make the second refrigerant pipe 32 arranged in an orderly manner. The first accommodating cavity 22 and the second accommodating cavity 23 are arranged in the fresh air pipe. Other pipelines can be placed in the first accommodating cavity 22 and the second accommodating cavity 23, thereby reducing the large space occupancy rate caused by the disordered arrangement of various pipelines, and the fresh air volume and the fresh air efficiency are as high as possible.

[0092] It should be noted that the air inlet cavity 21, the first accommodating cavity 22, and the second accommodating cavity 23 are configured to communicate with both ends of the fresh air pipe, that is, the air inlet cavity 21, the first accommodating cavity 22, and the second accommodating cavity 23 are arranged in the same length as the wall-penetrating section 20 and in the axial direction of the wall-penetrating section 20, so that the air inlet cavity 21 flows the air flow. The first accommodating cavity 22 is used to arrange the first refrigerant pipe 31, and the second accommodating cavity 23 is used to arrange the second refrigerant pipe 32. The air inlet cavity 21, the first accommodating cavity 22, and the second accommodating cavity 23 are not in communication with each other.

[0093] Thus, the first refrigerant pipe 31 and the second refrigerant pipe 32 are placed in the first accommodating cavity 22 and the second accommodating cavity 23 of the through-wall section 20, which are separated from the air inlet cavity 21, reducing the space occupancy caused by the disorderly arrangement of each pipe, thereby improving the fresh air volume and efficiency; the through-wall section 20 is arranged through the wall, which is simple to operate; and the first thermal insulation member 311 and the second thermal insulation member 321 interfere with the first opening 26 and the second opening 27 to ensure the stability of the first refrigerant pipe 31 and the second refrigerant pipe 32.

[0094] According to Figure 11 As shown in FIG. 2, when the first accommodating cavity 22 and the second accommodating cavity 23 are not connected, embodiments two and three are included. The transverse size of the first opening 26 is D, and A and D satisfy the relationship A≤D≤A+6mm. That is, the transverse size of the first opening 26 is greater than the outer diameter of the first refrigerant pipe 31, and the difference between the transverse size of the first opening 26 and the outer diameter of the first refrigerant pipe 31 is between 0-6mm, leaving a certain size allowance. When the first refrigerant pipe 31 is covered with the first thermal insulation member 311, the first refrigerant pipe 31 can also be placed in the first accommodating cavity 22 through the first opening 26.

[0095] Further, the transverse size of the second opening 27 is F, and B and F satisfy the relationship B≤F≤B+6mm. That is, the transverse size of the second opening 27 is greater than the outer diameter of the second refrigerant pipe 32, and the difference between the transverse size of the second opening 27 and the outer diameter of the second refrigerant pipe 32 is between 0-6mm, leaving a certain size allowance. When the second refrigerant pipe 32 is covered with the second thermal insulation member 321, the second refrigerant pipe 32 can also be placed in the second accommodating cavity 23 through the second opening 27.

[0096] Further, the transverse size of the first opening 26 is D, and the transverse size of the second opening 27 is F, and D and F satisfy the relationship 2mm≤D-F≤7mm. The first refrigerant pipe 31 is a gaseous refrigerant pipe, and the refrigerant flowing in the first refrigerant pipe 31 is gaseous refrigerant, and the refrigerant flowing in the second refrigerant pipe 32 is liquid refrigerant, so the outer diameter of the first refrigerant pipe 31 is greater than the outer diameter of the second refrigerant pipe 32, and the transverse size of the first opening 26 is greater than the transverse size of the second opening 27.

[0097] In addition, due to the size difference between the first refrigerant pipe 31 and the second refrigerant pipe 32, the difference between the transverse size of the first opening 26 and the transverse size of the second opening 27 is between 2mm-7mm, so that the first refrigerant pipe 31 can enter the first accommodating cavity 22 from the first opening 26, and the second refrigerant pipe 32 can enter the second accommodating cavity 23 from the second opening 27.

[0098] In the first embodiment, the second embodiment and the third embodiment, the wall-penetrating section 20 comprises a first tube body 24, the first tube body 24 is in a circular arc structure and the first tube body 24 is provided with a first opening 26 and a second opening 27. The first tube body 24 is in a circular arc structure, the first tube body 24 is in a discontinuous structure, i.e. the first tube body 24 is in a non-closed structure, and the first tube body 24 is provided with the first opening 26 and the second opening 27.

[0099] In the first embodiment, when the first accommodating cavity 22 and the second accommodating cavity 23 are communicated, the first refrigerant pipe 31 and the second refrigerant pipe 32 are placed in the first accommodating cavity 22 and the second accommodating cavity 23 through the opening 29 formed by the first opening 26 and the second opening 27.

[0100] In the second embodiment and the third embodiment, the first refrigerant pipe 31 is placed in the first accommodating cavity 22 through the first opening 26, and the second opening 27 is formed on the first tube body 24, and the second refrigerant pipe 32 is placed in the second accommodating cavity 23 through the second opening 27.

Specifically, the first tube body 24 and the second tube body 25 extend along the axial direction of the wall-penetrating section 20. The second tube body 25 is arranged in the first tube body 24, the second tube body 25 is connected with the inner wall of the first tube body 24, and the second tube body 25 separates the first tube body 24 to form the air inlet cavity 21, the first accommodating cavity 22 and the second accommodating cavity 23 in the first tube body 24.

[0102] 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 part of the first tube body 24, and the first refrigerant pipe 31, the second refrigerant pipe 32, the wire pipe 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 pipe 31, the second refrigerant pipe 32, the wire pipe 34 and the drain pipe 33 are neatly arranged.

[0103] The other side of the second tube body 25 and the other part of the first tube body 24 form the closed air inlet cavity 21, and the air inlet cavity 21 communicates with the outdoor and the fresh air module, so as to introduce the fresh air from the outdoor to the fresh air module, and the fresh air enters the indoor under the operation of the fresh air module to purify the indoor air.

[0104] As Figure 2As shown, in the first and second embodiments, the second tube body 25 includes a plurality of arcuate segments 251, which are interconnected and disposed opposite the first opening 26 and the second opening 27. Each of the arcuate segments 251 is recessed toward the side facing away from the first opening 26 and the second opening 27. The second tube body 25 is formed by sequentially connecting the plurality of arcuate segments 251, which are recessed toward the first opening 26 and the second opening 27. Each of the arcuate segments 251 forms an arcuate receiving portion. One of the arcuate segments 251 is connected to the inner wall of one side of the first tube body 24, and one of the arcuate segments 251 can be used to accommodate the drain pipe 33. Another arcuate segment 251 is connected to the inner wall of the other side of the first tube body 24, and another arcuate segment 251 can be used to accommodate the electrical conduit 34. The plurality of arcuate segments 251 are sequentially connected to form a plurality of receiving portions for accommodating the first refrigerant pipe 31, the second refrigerant pipe 32, the drain pipe 33, and the electrical conduit 34.

[0105] In embodiment three, there can be two second tube bodies 25, one side of one second tube body 25 and a portion of the first tube body 24 form a first accommodating chamber 22; one side of the other second tube body 25 and another portion of the first tube body 24 form a second accommodating chamber 23, and the first accommodating chamber 22 and the second accommodating chamber 23 are arranged at axial intervals around the wall-penetrating section 20 and are not connected to each other; the other side of one second tube body 25 and the other side of the other second tube body 25 and another portion of the first tube body 24 form a circumferentially closed air inlet chamber 21, and the air inlet chamber 21 is not connected to the first accommodating chamber 22 and the second accommodating chamber 23.

[0106] like Figure 9 As shown, in the second embodiment, when the first accommodating chamber 22 and the second accommodating chamber 23 are not connected and are arranged adjacent to each other, the wall-penetrating section 20 further includes a third tube 28, one end of which is connected to the second tube 25, and the other end of the third tube 28 extends 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 wire pipe 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.

[0107] like Figure 7 and Figure 9As shown, at least one end of the first opening 26 is provided with a first undercut 241 located on the side of the first pipe body 24 facing the center of the circle. The structure of the first pipe body 24 is discontinuous to form the first opening 26, and at least one end of the first opening 26 is provided with a first undercut 241 located on the side of the first pipe body 24 facing the center of the circle. The first undercut 241 is provided on the outer wall of the first pipe body 24, and the first undercut 241 is located on the side of the first pipe body 24 facing the center of the circle. The first undercut 241 can increase the friction between the first pipe body 24 and the first refrigerant pipe 31, preventing the first refrigerant pipe 31 from popping out of the opening 29.

[0108] In addition, at least one end of the second opening 27 is provided with a second undercut 242 located on the side of the first pipe body 24 facing the center of the circle. The structure of the first pipe body 24 is discontinuous to form the second opening 27, and at least one end of the second opening 27 is provided with a second undercut 242 located on the side of the first pipe body 24 facing the center of the circle. The second undercut 242 is provided on the first pipe body 24, and the second undercut 242 is located on the side of the first pipe body 24 facing the center of the circle. The second undercut 242 can increase the friction between the first pipe body 24 and the second refrigerant pipe 32, preventing the second refrigerant pipe 32 from popping out of the opening 29.

[0109] Wherein, the first heat preservation member 311 and the second heat preservation member 321 can be sponges, the first refrigerant pipe 31 and the second refrigerant pipe 32 are separately arranged, preventing extrusion between the first heat preservation member 311 and the second heat preservation member 321 (i.e. sponge and sponge), the first heat preservation member 311 can prevent extrusion of the wire pipe 34 and the drain pipe 33, and the second heat preservation member 321 allows the first refrigerant pipe 31 to tightly fit the second accommodating cavity 23, thereby reducing the space for pipe arrangement (i.e. the space of the first accommodating cavity 22) and increasing the space of the air inlet cavity 21.

[0110] By arranging the first refrigerant pipe 31 on the side of the first opening 26, it is avoided that the first opening 26 is arranged inside the wire pipe 34 or the drain pipe 33, and the outer periphery of the wire pipe 34 and the drain pipe 33 has no sponge, which causes a problem of poor assembly. Meanwhile, the sponge, as a material with expansion property, can be pressed at the first opening 26, and the excess space at the first opening 26 is utilized, which facilitates assembly of the wall penetrating section 20 during the overall wall penetrating process by pressing the sponge at the first opening 26 by hand, instead of pressing the sponge by the drain pipe 33 and the wire pipe 34, which is inconvenient to operate.

[0111] By arranging the second refrigerant pipe 32 on the side of the second opening 27, the sponge, as a material with expansion property, can be pressed at the second opening 27, and the excess space at the second opening 27 is utilized, which facilitates assembly of the wall penetrating section 20 during the overall wall penetrating process by pressing the sponge at the second opening 27 by hand.

[0112] Thus, the first refrigerant pipe 31 and the second refrigerant pipe 32 are respectively placed in the first accommodating cavity 22 and the second accommodating cavity 23, the first accommodating cavity 22 and the second accommodating cavity 23 are separated from the air inlet cavity 21, the space occupation rate caused by the disorder of each pipe line is reduced, thereby improving the fresh air volume and the fresh air efficiency; the through-wall section 20 is arranged through the wall, and the operation is simple; the first opening 26 does not need to be provided with a cover, and the first reverse tooth 241 is arranged at least one end of the first opening 26, and the reverse tooth can avoid the first refrigerant pipe 31 from being popped out.

[0113] In addition, the second opening 27 does not need to be provided with a cover, and the second reverse tooth 242 is arranged at least one end of the second opening 27, and the reverse tooth can avoid the second refrigerant pipe 32 from being popped out.

[0116] The cross-sectional shape of the second section is consistent with the cross-sectional shape of the air inlet cavity 21, so that the first section and the air outlet end of the air inlet cavity 21 are matched, so that the first section and the air outlet end of the air inlet cavity 21 are tightly connected, and the air leakage phenomenon at the connection between the first section and the air inlet cavity 21 is avoided.
