Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to a rapid installation device for air conditioning units. Background Technology

[0002] When conducting enthalpy difference tests on vehicle-mounted air conditioners, a dedicated enthalpy difference chamber assembly and testing fixture 2 is required to assemble and fix the air conditioning unit within the test chamber. In existing technology, conventional rail vehicle air conditioning enthalpy difference chamber testing fixtures employ a frame-type fixture 2 + phenolic foam board duct + aluminum foil tape structure, as detailed below. Figure 1 As shown,

[0003] The first return air duct 3, second return air duct 4, first supply air duct 5, and second supply air duct 6 installed in the experimental fixture 2 all need to be pre-assembled using phenolic foam boards and aluminum foil tape. After assembly, personnel enter the experimental fixture 2 and manually adjust the positions of the first return air duct 3, second return air duct 4, first supply air duct 5, and second supply air duct 6 so that the first return air duct 3 and second return air duct 4 are compatible with the two return air inlets of the air conditioning unit, and the first supply air duct 5 and second supply air duct 6 are compatible with the two supply air outlets of the air conditioning unit. Then, aluminum foil tape is used to seal and bond each duct opening and the air outlet of the air conditioning unit, thus completing the installation work for the air conditioning performance test. When dealing with different models of units, multiple sets of ducts need to be assembled and bonded. The disadvantage of the above-mentioned conventional rail vehicle air conditioning enthalpy difference chamber installation fixture is:

[0004] 1) Phenolic foam board ducts require phenolic foam boards to be assembled and glued according to the size of the air outlet, which is time-consuming and labor-intensive, and the glued ducts are easily damaged.

[0005] 2) The air conditioning vents and phenolic foam board ducts are poorly compatible, requiring manual adjustment of the phenolic foam board ducts, which affects the installation efficiency.

[0006] 3) The phenolic foam board duct must be bonded to the bottom air vent of the air conditioning unit using aluminum foil tape. Poor bonding may lead to air leakage, affecting the accuracy of the enthalpy difference test.

[0007] 4) Two supply air ducts and two return air ducts need to be bonded together. The ducts need to be frequently disassembled and take up space. When dealing with two different models of standardized subway air conditioning units, new ducts need to be spliced ​​together with phenolic foam boards.

[0008] 5) Each time an air conditioning unit is installed, an external condensate drain pipe needs to be connected to each drain outlet, which affects the installation efficiency. Utility Model Content

[0027] 4) Quick installation: When faced with two different models of standardized subway air conditioning units, only the air supply duct on the body assembly needs to be replaced. There is no need to adjust all the ducts, which is simple and quick.

[0028] 5) It has a water collection tray that is compatible with different models of units. After the air conditioner condensate drips into the water collection tray, it is discharged through the external water pipe.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0044] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] This utility model provides a rapid installation device for an air conditioning unit, comprising: a housing assembly including a supply air transfer duct 16 and a return air transfer duct 17, which can be disassembled and replaced according to the model of the air conditioning unit 1; the supply air transfer duct 16 is connected to the air supply outlet of the air conditioning unit 1, and the return air transfer duct 17 is connected to the return air outlet of the air conditioning unit 1; a tooling carriage 9, which loads the housing assembly and moves it, and the housing assembly is slidably connected to the interior of the tooling carriage 9; and a limiting component, which is assembled and fixed with the tooling carriage 9 to limit the relative position of the housing assembly within the tooling carriage 9.

[0047] Standardized subway air conditioning units are available in two types: Type A and Type B. Figure 2 As shown, the return air vents and their relative positions are the same for both models, as are the supply air vents. However, the distance between the supply air vents differs between the two models: the center-to-center distance between the two supply air vents is 1560mm for model A and 1380mm for model B. Therefore, this difference in supply air vent distance must be fully considered when installing the equipment in the enthalpy difference test chamber.

[0048] The rapid installation equipment for air conditioning units provided in this embodiment includes a chassis assembly and a tooling vehicle 9; such as Figure 3 and Figure 4 As shown, the tooling vehicle 9 is a frame structure made of square tubes welded together, including longitudinal beams and transverse beams. The body assembly is set inside the frame, and the air conditioning unit 1 to be tested is set on top of the tooling vehicle 9 and supported by the top transverse beam.

[0049] The tooling carriage 9 has a V-shaped guide rail 7 on its bottom crossbeam. The box assembly includes a box body 8, and the bottom of the box body 8 is equipped with a box body pulley 12 or other structure that can slide along the V-shaped guide rail 7, including but not limited to the box body pulley 12, slider, ball bearing, etc., so that the box body 8 can slide along the crossbeam to adjust the position of the box assembly inside the tooling carriage 9. In practical applications, a connection structure between the bottom crossbeam and the bottom of the box body 8 can be set as needed to allow the box body 8 to move along the bottom crossbeam.

[0050] A limiting component is provided on the bottom crossbeam. Depending on the type of air conditioning unit 1 to be assembled and the placement position of the air conditioning unit 1, the compartment component is pushed along the V-shaped guide rail 7 to a position that facilitates assembly and connection with the air conditioning unit 1. The limiting component then limits the position of the compartment component on the bottom crossbeam to prevent the compartment component from moving again.

[0051] In this embodiment, the limiting assembly includes a body limiting plate and a tooling vehicle limiting plate 10. The body limiting plate is fixed to the side wall and / or bottom wall of the body 8, without affecting the sliding of the body assembly. The tooling vehicle limiting plate 10 is fixed to any position of the bottom crossbeam or the tooling vehicle 9, or the tooling vehicle limiting plate 10 is directly integrated with the crossbeam. Bolt holes are correspondingly provided on the body limiting plate and the tooling vehicle limiting plate 10. The body assembly slides along the V-shaped guide rail 7 within the tooling vehicle 9. When it slides to a designated position, the body limiting plate at the rear of the body assembly is bolted to the tooling vehicle limiting plate 10 on the tooling vehicle 9, thereby limiting the position of the body assembly within the tooling vehicle 9.

[0052] An air conditioning unit limiting device is also installed on the top crossbeam of the tooling vehicle 9 frame to limit the position of the air conditioning unit 1 on the roof of the tooling vehicle. The air conditioning unit limiting device includes a first air conditioning unit limiting device 11 and a second air conditioning unit limiting device 13. The two limiting devices are bolted to the top crossbeam of the tooling vehicle frame. The first air conditioning unit limiting device 11 is used to limit the position of the air conditioning unit 1 in the width direction, and the second air conditioning unit limiting device 13 is used to limit the position of the air conditioning unit 1 in the length direction.

[0053] The body assembly and air conditioning unit 1 are assembled together with the tooling vehicle 9 using limiting components and unit limiting devices.

[0054] like Figure 5 As shown, the compartment assembly includes a compartment 8, which is a cavity structure with a compartment top cover 19 on the top. The compartment 8 is provided with a return air transfer duct 17, a supply air transfer duct 16, a compartment supply air duct 15, and a compartment return air duct 14.

[0055] The return air transfer duct 17 and the supply air transfer duct 16 are both connected to the top surface of the box top cover 19 by bolts. Figure 5 As shown, there are two return air transfer ducts 17 and two supply air transfer ducts 16, which are arranged opposite each other and in parallel. The flange faces of the return air transfer duct 17 and the supply air transfer duct 16 are equipped with seals to prevent air leakage.

[0056] At the bottom of the top cover 19 of the compartment, where the air supply transfer duct 16 is located, there is a compartment air supply duct 15. Inside the compartment 8, the compartment air supply duct 15 is connected to the two air supply transfer ducts 16 above the top cover 19 of the compartment. The compartment air supply duct 15 and the top cover 19 of the compartment are also connected by bolts. The flange surface of the compartment air supply duct 15 is also provided with a sealing element.

[0057] The return air duct 14 of the compartment adopts an open structure, extending directly to the indoor side. The return air from the indoor side directly enters the return air transfer duct 17 through the interior of the compartment 8, and finally enters the return air chamber of the air conditioning unit.

[0058] A water collection tray 18 is also provided on the top of the top cover 19 of the compartment. The water collection tray 18 is located on the side of the return air transfer duct 17 and is parallel to the return air transfer duct 17. It is used to collect the condensate flowing out of the air conditioning unit 1 and discharge it through the drain pipe. The top cover 19 of the compartment is provided with a limiting block for the water collection tray 18. The water collection tray 18 can be placed according to the limiting block.

[0059] refer to Figure 7 As shown, the test environment is divided into an indoor side and an outdoor side by the wall 21; the standardized subway air conditioning unit 1 is placed on the frame of the tooling car 9 according to the first air conditioning unit limit device 11 and the second air conditioning unit position. The air conditioning unit 1 presses the sealing strip in the groove on the flange surface of the supply air transfer duct 16 and the return air transfer duct 17 by its own weight, so as to achieve a sealed connection between the air conditioning unit 1 and the transfer duct.

[0060] An indoor air duct 23 is installed, which connects to the housing air duct 15 via an air supply duct-air duct-air duct transition 22. During assembly, the housing air duct 15 and the air supply duct-air duct transition 22 are connected by bolts. A sealing element is installed on the flange surface of the housing air supply duct 15 to effectively prevent air leakage during the duct connection process. The air supply duct-air duct transition 22 and the air duct 23 are crimped together using bolt cutters to ensure that the unit's air supply enters the air duct 23.

[0061] The return air duct 14 extends directly to the indoor side to facilitate the intake of return air from the indoor side into the air conditioning unit 1.

[0062] The air supply duct-wind tunnel transition duct 22 is connected by bolts, and the air supply duct-wind tunnel transition duct 22 and 23-wind tunnel are crimped with pliers to ensure that the unit's air supply enters the wind tunnel 23; the compartment return air duct 14 extends directly to the indoor side to facilitate the intake of the indoor return air into the air conditioning unit 1.

[0063] In this embodiment, the air supply conversion duct 16 is applicable to the air conditioning unit of a type A vehicle. The air supply conversion duct and the body 8 are interchangeable. When it is necessary to perform an installation test on the air conditioning unit of a type B vehicle, Figure 3The air supply duct 16 near the top center crossbeam of the tooling vehicle 9 is replaced with a custom-shaped air supply duct 20 suitable for the air conditioning unit 1 of the B-type vehicle. The custom-shaped air supply duct 20 is then bolted to the top cover 19 of the vehicle body to ensure that the spacing between the air supply ducts matches the interface size of the B-type vehicle air conditioning unit, thus achieving compatibility between the air outlets of the A-type and B-type vehicle air conditioning units. After installing the custom-shaped air supply duct 20, as... Figure 6 As shown.

[0064] The specific structure of the air supply adapter duct 20 is not required; it only needs to allow for adjustment of the distance between the two air supply adapter ducts 16. For example, the main structure can be a retractable threaded tube, and the distance between the two air supply adapter ducts 16 can be adjusted by the deformation of the threaded tube. In practical applications, the air supply adapter duct 20 can also be a Z-shaped structure, with the connecting duct in the middle being retractable to achieve the adjustment of the distance.

[0065] Preferably, in the embodiments provided in this application, each air duct, including but not limited to the compartment return air duct 14, the compartment supply air duct 15, the supply air transfer duct 16, the return air transfer duct 17, the supply air transfer irregular air duct 20, and the supply air duct-wind tunnel transfer duct 22, is made of aluminum alloy. Insulation cotton is pasted on both the inner and outer sides of the supply air duct-wind tunnel transfer duct 22. The specific pasting position and thickness are the same as the usage status of the air conditioning unit 1 on a standardized subway rail vehicle.

[0066] After the air conditioning unit 1 and the compartment components are assembled, the tooling cart 9 is pushed to move the air conditioning unit 1 and the compartment components towards the wall 21, and finally connects the compartment air supply duct 15, the air supply duct-wind tunnel transition duct 22 and the wind tunnel 23 to form a complete air duct. Then the enthalpy difference test begins.

[0067] The assembly and connection of each air duct and the enthalpy difference test process are conventional techniques in this field and will not be described in detail. Any existing or future technologies are applicable to this utility model and should not be considered as not being proposed due to the foregoing description in this application.

[0068] In summary, the rapid installation equipment for air conditioning units provided by this utility model has the following advantages compared with the prior art:

[0069] 1) The special tooling vehicle body is made of aluminum alloy, with thermal insulation cotton pasted on both the inner and outer sides, and can be used permanently while ensuring test performance;

[0070] 2) The air conditioning unit can be directly adapted to each connecting air duct according to the position of the limit device, without the need for manual adjustment, thus improving the installation efficiency;

[0071] 3) The air conditioning unit uses its own weight to press against the sealing strip in the groove, which can directly ensure the airtightness between the air duct and the air outlet;

[0072] 4) Quick installation: When faced with two different models of standardized subway air conditioning units, only the air supply duct on the body assembly needs to be replaced. There is no need to adjust all the ducts, which is simple and quick.

[0073] 5) It has a water collection tray that is compatible with different models of units. After the air conditioner condensate drips into the water collection tray, it is discharged through the external water pipe.

[0074] 6) The internal space of the compartment components can be used as a return air duct, eliminating the need for a separate return air duct design.
