[0035] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inside", "outside", "front", "back", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] As a specific embodiment of the present invention, Figures 1 to 4 As shown, the present embodiment discloses an air supply duct 300, which is used to supply air to the air conditioner 100. Specifically, the air conditioner 100 may be a duct-type air conditioner, the fuselage 200 of which is arranged outside, and the fuselage 200 is provided with an evaporator 220, a condenser 230, a compressor 240 and a fan 250. The air supply duct 300 delivers the gas in the fuselage 200 into the target space 400. The air supply duct 300 is provided with an outlet duct 310 and a return duct 320 arranged side by side. The air supply duct 300 of the present embodiment may include a wall-penetrating section 350, which is used to pass through the wall so that the end of the air supply duct 300 extends into the target space 400, and the ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 100 is less than or equal to 57.37 cm 2 / kw, wherein the cross-sectional area of ​​the through-wall section 350 is less than or equal to 200cm 2 .

[0037] Specifically, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 of the present embodiment to the cross-sectional area of ​​the wall-penetrating section 350 and the power of the air conditioner 100 is less than or equal to 57.37 cm 2 For example, when the power of the air conditioner 100 of the wall-penetrating section 350 of this embodiment is 1.5 hp or above, the upper limit of the cross-sectional area of ​​the wall-penetrating section 350 is 200 cm 2 When the power of the air conditioner 100 is smaller, the cross-sectional area of ​​the through-wall section 350 can be smaller. In addition, on the one hand, power has a greater limitation on the cross-sectional area, and the cross-sectional area of ​​the air supply duct 300 under a certain power is certain. On the other hand, it is limited by existing laws and regulations, and the cross-sectional area cannot be infinite. In this embodiment, the ratio of the cross-sectional area of ​​the through-wall section 350 of the air supply duct 300 to the power is less than or equal to 57.37 cm 2 / kw, and the cross-sectional area of ​​the wall-penetrating section is less than or equal to 200cm 2 , while meeting the requirements of the size of the through-wall section, it further meets the power requirements of the air conditioner 100.

[0038] As one of the embodiments, Figure 5 and Figure 6 As shown, one fuselage 200 of the present embodiment may be equipped with one air supply duct 300 . Of course, in other embodiments, one fuselage 200 may be equipped with a plurality of air supply ducts 300 .

[0039] More specifically, Figure 6 As shown, each air supply duct 300 may include a main pipe 330 and at least one branch pipe 340 , one end of each branch pipe 340 is connected to the main pipe 330 , and the other end is connected to the corresponding target space 400 to supply air to the target space 400 .

[0040] When one fuselage 200 is equipped with one air supply duct 300, and there are many target spaces 400, one main pipe 330 and multiple branch pipes 340 can be used to supply air to different target spaces 400 (e.g. Figure 6 When a fuselage 200 is equipped with multiple air supply ducts 300, and there are many target spaces 400, each air supply duct 300 may include a main pipe 330, and the number of target spaces 400 and the number of air supply ducts 300 are matched, and each air supply duct 300 may supply air to one of the target spaces 400 (e.g. Figure 5 shown).

[0041] As a specific embodiment of the present invention, Figure 7 and Figure 8 As shown, each air supply duct 300 of the present embodiment may include a wall-penetrating section 350, which is used to pass through the cavity so that the end of the air supply duct 300 extends into the target space 400, and the cross-section of the wall-penetrating section 350 is circular, and the diameter of the wall-penetrating section 350 is less than or equal to 160 mm.

[0042] Specifically, each air supply duct 300 of the present embodiment needs to pass through the wall to enter the target space 400. Therefore, each air supply duct 300 of the present embodiment may include a wall-penetrating section 350. The wall-penetrating section 350 of the present embodiment may be circular, and the diameter is less than or equal to 160 mm, and the diameter of the wall-penetrating section is matched with the case where the power of the air conditioner 100 is greater than 1.5 HP. In this way, the power requirement of the air conditioner 100 is met on the one hand, and the requirement that the wall-penetrating hole cannot be too large is also met on the other hand.

[0043] In addition, the structure of most general through-wall holes is circular, so the through-wall segment 350 of this embodiment is preferably circular.

[0044] Specifically, the cross-sectional shape of the wall-penetrating section 350 of the present embodiment may be circular, square or other shapes. Preferably, the shape of the wall-penetrating section 350 of the air conditioner 100 of the present embodiment is circular, and the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm 2 , that is, the diameter is less than or equal to 160mm.

[0045] As a specific embodiment of the present invention, the air volume of the air supply duct 300 of the hole in this embodiment is 650m 3 / h~11000m 3 / h. For example, the air volume can be 650m 3 / h、700m 3 / h、750m 3 / h、800m 3 / h、900m3 / h、1000m 3 / h or 1100m 3 / h, etc.

[0046] Specifically, when the air supply duct 300 of this embodiment is fully internally circulated and the wall-penetrating section 350 of the air supply duct 300 is limited to a diameter of 160 mm, the air intake volume of this embodiment can reach 650 m 3 / h~700m 3 When the air supply duct 300 of this embodiment not only has internal circulation but also combines external fresh air, the air intake volume of the air supply duct 300 of this embodiment can reach 1100m 3 / h or even higher.

[0047] Specifically, the air intake volume is related to the diameter of the air supply duct 300 on the one hand, and is also related to the power of the centrifugal fan on the other hand. Of course, the size of the equipment's fresh air opening will also have a certain impact on the air intake volume.

[0048] As a specific embodiment of the present invention, Figure 7-Figure 10 As shown, each main pipe 330 and branch pipe 340 of the present embodiment may include a pipe body 360 and a partition 370, wherein the partition 370 located inside the pipe body 360 extends in a direction parallel to the extension direction of the pipe body 360, dividing the pipe body 360 into an outlet air duct 310 and a return air duct 320.

[0049] More specifically, the cross-sectional areas of the outlet air duct 310 and the return air duct 320 of this embodiment are the same, so that the air volumes of the inlet air and the return air can be equal.

[0050] When the air supply duct 300 includes the main pipe 330 and the branch pipe 340 , the outlet duct 310 of the main pipe 330 is communicated with the outlet duct 310 of the branch pipe 340 , and the return air duct 320 of the main pipe 330 is communicated with the return air duct 320 of the branch pipe 340 .

[0051] Specifically, when the air supply duct 300 of this embodiment includes the main pipe 330 and the branch pipe 340 , the wall-penetrating section 350 is located at the branch pipe 340 .

[0052] More specifically, the cross section of the air supply duct 300 at the wall penetration section 350 of this embodiment can be designed to be circular, while the ducts at other locations can be designed to be circular (such as Fig. 9 For example, the duct between the through-wall section 350 and the fuselage 200 can be designed to be square, such as a rectangle (such as Fig.10 Such a design can make the air supply duct 300 more beautiful and more convenient to install when it is outside the wall, and the wall penetration section 350 can better match the wall penetration hole.

[0053] As a specific embodiment of the present invention, a heat-insulating layer (not shown in the figure) is provided on the wall of the air supply duct 300 of this embodiment. The heat-insulating layer can keep the gas in the air supply duct 300 warm and isolate it from the external ambient temperature, thereby reducing the influence of the external environment on the temperature of the transported gas during the transport process.

[0054] As a specific embodiment of the present invention, Fig. 9 and Fig.10 As shown, the air supply duct 300 of this embodiment is formed by one or more duct units 380. When the air supply duct 300 is formed by connecting multiple duct units 380, the multiple duct units 380 are interlocked and spliced ​​to form the entire duct. Specifically, a clamping ring 390 (such as Fig. 9 As shown), the clamping ring 390 clamps the ends of the pipe units 380 on both sides together and seals them.

[0055] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
