[0030] In the description of the present embodiment, it needs to be understood that the terms "length", "width", "height", "upper", "lower", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "back" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present utility model.
[0031] As a specific embodiment of the present utility model, as shown in Figures 1-3 The present embodiment discloses a supply air duct 300, which is used for supplying air for an air conditioner 100, and specifically the air conditioner 100 can be a ducted air conditioner, the body 200 of the ducted air conditioner is arranged outside, and the body 200 is internally provided with an evaporator 220, a condenser 230, a compressor 240 and a fan 250. The supply air duct 300 supplies the gas in the body 200 into a target space 400.
[0032] More specifically, as shown in Figure 3 , Figure 4 and Figure 6 The supply air duct 300 of the present embodiment can include a wall-penetrating section 310, a transition section 320 and a supply air section 330 connected in sequence, the transition section 320 can include a first end portion 321 close to the wall-penetrating section 310 and a second end portion 322 close to the supply air section 330, the structure of the pipe wall of the transition section 320 at the first end portion 321 is the same as that of the wall-penetrating section 310, and the structure of the pipe wall of the transition section 320 at the second end portion 322 is the same as that of the supply air section 330.
[0033] Specifically, the supply air duct 300 of the present embodiment can include a wall-penetrating section 310, a transition section 320 and a supply air section 330, and the transition section 320 is arranged between the wall-penetrating section 310 and the supply air section 330. When different supply air sections 330 or different wall-penetrating sections 310 are used according to different situations, only the structure of the transition section 320 needs to be changed, and the pipe structures of other parts do not need to be changed, thereby improving the versatility of the pipe and reducing the production cost.
[0034] For example, when the size of the wall-penetrating section 310 changes, the size of the end of the transition section 320 close to the wall-penetrating section 310 can be changed, thereby not needing to change the structure of the pipe of the supply air section 330, and reducing the production cost.
[0035] As a specific embodiment of the utility model, the cross-sectional structure of the pipe wall of the wall-penetrating section 310 is different from that of the air supply section 330, and the cross-sectional structure of the pipe wall of the first end portion 321 of the transition section 320 is different from that of the second end portion 322.
[0036] Specifically, the cross-sectional structure of the pipe wall of the wall-penetrating section 310 can be circular, while the cross-sectional structure of the pipe wall of the air supply section 330 can be square (as shown in Figure 4 ) or circular (as shown in Figure 5 ). When the cross-sectional structure of the pipe wall of the air supply section 330 is square, the cross-sectional structure of the pipe wall of the wall-penetrating section 310 is different from that of the air supply section 330, so that the cross-sectional structure of the pipe wall of the first end portion 321 of the transition section 320 is different from that of the second end portion 322, and thus the transition of the transition section 320 is more needed between the wall-penetrating section 310 and the air supply section 330.
[0037] More specifically, as shown in Figure 6 , the cross-sectional structure of the pipe wall of the wall-penetrating section 310 is circular, the cross-sectional structure of the pipe wall of the air supply section 330 is square, the cross-sectional structure of the pipe wall of the first end portion 321 of the transition section 320 is circular, the cross-sectional structure of the pipe wall of the second end portion 322 of the transition section 320 is square, and the cross-sectional structure of the pipe wall of the transition section 320 gradually transitions from circular to square from the first end portion 321 to the second end portion 322.
[0038] Specifically, generally, the flow of gas flow is related to the cross-sectional area of the air supply pipeline 300, but is affected by external factors, and the structure is different under the same cross-sectional area. For example, since the wall-penetrating hole is preferably circular, the wall-penetrating section 310 of the air supply pipeline 300 is preferably circular. In addition, since the air supply section 330 is located outside the wall, it is more appropriate to form the cross-sectional shape of the pipe wall of the air supply section 330 into a square (as shown in Figure 4 ) (including a rectangle and a square, preferably a rectangle), so that the transition section 320 needs to be transitioned from circular to square, and the airflow can be smoother through the transition section 320. When the size of the wall-penetrating section 310 changes or the structure of the air supply section 330 changes, only the size or structure of the transition section 320 can be changed, thereby increasing the universality and reducing the production cost.
[0039] As a specific embodiment of the utility model, as shown in Figure 3 and Figure 5As shown, the air supply pipeline 300 of the embodiment can also include partitions 340 to separate the air supply pipeline 300 into an air inlet duct 350 and an air return duct 360, and the partitions 340 at the through-wall section 310, the transition section 320 and the air supply section 330 are connected in sequence.
[0040] More specifically, as shown, Figure 6 the plane of the partition 340 at the through-wall section 310 and the plane of the partition 340 at the air supply section 330 have a preset angle, so that the transition section 320 is located between the plane of the partition 340 at the first end 321 and the plane of the partition 340 at the second end 322 has a preset angle; wherein the preset angle is 0-90°.
[0041] Specifically, the closed cross-sectional structure of the through-wall section 310 and the air supply section 330 of the embodiment can both be circular, so that the cross-sectional dimensions of the entire through-wall section 310, air supply section 330 and transition section 320 are consistent, and the partitions 340 are also in the same plane, i.e. the preset angle is 0°. Of course, when the cross-sectional structure of the pipe wall of the air supply section 330 is square and the cross-sectional structure of the pipe wall of the through-wall section 310 is circular, the preset angle can also be 0 degrees. Of course, due to the structure of the air outlet duct, the preset angle can also be other angles. For example, as shown in Figure 4 and Figure 6 Since the plane of the air outlet of the air outlet duct is 45° to the horizontal plane, the partition 340 of the through-wall section 310 is 45° to the horizontal plane, and the partition 340 of the air supply section 330 is 90° to the horizontal plane, so the partition 340 of the through-wall section 310 is 45° to the partition 340 of the air supply section 330. And since the partition 340 at the first end 321 of the transition section 320 is connected to the partition 340 of the through-wall section 310, and the partition 340 at the second end 322 of the transition section 320 is connected to the partition 340 of the air supply section, in order to avoid the position of the partition 340 suddenly changing and causing gas turbulence, the partition 340 of the transition section 320 of the embodiment gradually bends from the first end 321 to the second end 322.
[0042] Preferably, the cross-sectional areas of the air inlet duct 350 and the air return duct 360 of the embodiment are the same, which can ensure that the air inlet and air return volumes are comparable.
[0043] As a specific embodiment of the utility model, as shown in Figure 7 the ratio of the cross-sectional area of the through-wall section 310 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 310 is less than or equal to 200 cm 2 .
[0044] Specifically, the ratio of the cross-sectional area of the wall-penetrating section 310 of the air supply duct 300 to the power of the air conditioner 100 is less than or equal to 57.37 cm 2 / kw. For example, when the power of the air conditioner 100 is 1.5 tons or more, the upper limit of the cross-sectional area of the wall-penetrating section 310 is 200 cm 2 . When the power of the air conditioner 100 is less, the cross-sectional area of the wall-penetrating section 310 can be smaller. On the one hand, the power has a greater limit on the cross-sectional area, and on the other hand, the cross-sectional area cannot be infinite due to the existing laws and regulations. The ratio of the cross-sectional area of the wall-penetrating section 310 of the air supply duct 300 to the power of the air conditioner 100 is less than or equal to 57.37 cm 2 / kw, and the cross-sectional area of the wall-penetrating section 310 is less than or equal to 200 cm 2 . The size of the wall-penetrating section 310 meets the regulations, and further meets the power demand of the air conditioner 100.
[0045] As a specific embodiment of the utility model, preferably, the closed cross-section of the wall-penetrating section 310 of the embodiment is circular, and the diameter of the wall-penetrating section 310 is less than or equal to 160 mm.
[0046] Specifically, each air supply duct 300 of the embodiment needs to pass through the wall to enter the target space 400, so each air supply duct 300 of the embodiment can include a wall-penetrating section 310, the wall-penetrating section 310 of the embodiment can be circular, and the diameter is less than or equal to 160 mm, and the diameter of the wall-penetrating section 310 matches the case where the power of the air conditioner 100 is greater than 1.5 tons. In this way, on the one hand, the power demand of the air conditioner 100 is met, and on the other hand, the demand that the wall hole cannot be too large is also met.
[0047] In addition, the structure of the general wall hole is mostly circular, so the wall-penetrating section 310 of the embodiment is preferably circular.
[0048] As a specific embodiment of the utility model, the air supply duct 300 of the embodiment has an air inlet air volume of 650 m 3 / h ~ 11000 m 3 / h. For example, the air inlet air volume can be 650 m 3 / h, 700 m 3 / h, 750 m 3 / h, 800 m 3 / h, 900 m 3 / h, 1000 m 3 / h, or 1100 m 3 / h, etc.
[0049] Specifically, when the complete inner circulation of the present embodiment and the penetration wall section 310 of the air inlet duct at this time is limited to a diameter of 160 mm, the air inlet volume of the present embodiment can reach 650 m 3 / h ~ 700 m 3 / h. And when the present embodiment not only has inner circulation, but also combines with external fresh air, the air inlet volume of the air inlet duct of the present embodiment can reach 1100 m 3 / h or even higher.
[0050] Specifically, the air inlet volume is related to the pipe diameter of the air inlet duct 300 on the one hand, and the power of the centrifugal fan, the size of the device fresh air opening, etc. will also have a certain influence on the air inlet volume.
[0051] As a specific embodiment of the present application, the air supply duct 300 of the present embodiment is provided with a layer of heat preservation layer (not shown in the figure) at the pipe wall. The heat preservation layer can heat the gas in the air supply duct 300 and isolate the outside environment temperature, reducing the influence of the outside environment on the temperature of the gas during transportation.
[0052] As a specific embodiment of the present application, as shown in Figure 4 and Figure 5 The air supply duct 300 of the present embodiment is formed by one or more duct units 370. When the air supply duct 300 is formed by connecting multiple duct units 370, the entire duct is obtained by mutually clamping and splicing the multiple duct units 370. Specifically, a clamping ring 380 (as shown in Figure 5 ) can also be provided at the connection position of the duct unit 370 and the duct unit 370, which clamps and seals the end portions of the two duct units 370.
[0053] At this point, those skilled in the art should realize that although the present application has been shown and described in detail in the present application, many other variants or modifications conforming to the principles of the present application can be directly determined or deduced according to the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variants or modifications.
