Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to an air conditioning unit. Background Technology

[0002] Some air conditioning units have built-in compressors, such as vertical direct expansion units. In their refrigeration system, the liquid refrigerant evaporates (expands) directly in its evaporator coil to absorb heat from the air outside the coil and thus achieve cooling. Direct expansion units are usually made as an integral structure and placed in a specific space such as a machine room.

[0003] When installing air conditioning units such as direct expansion units, the installation space is limited, and the overall size requirements of the unit are relatively high. Specific machine rooms are required for installation. To adapt to the machine room space, the size of the air conditioning unit may need to be reduced, leading to problems such as a smaller heat exchanger and insufficient heat exchange capacity.

[0068] In this application, the air conditioning unit performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0069] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0070] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioning unit regulates the temperature of the indoor space.

[0071] The outdoor unit of an air conditioning unit refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioning unit includes the indoor heat exchanger, and the expansion valve can be provided in either the indoor or outdoor unit.

[0072] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioning unit functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioning unit functions as a cooler in cooling mode.

[0073] refer to Figures 1-3 In one aspect, the present invention proposes an air conditioning unit, which includes an indoor unit and an outdoor unit. The indoor unit includes a housing 100, a compressor 200, a heat exchanger 300, and a support assembly 400. Another heat exchanger is installed in the outdoor unit. The two heat exchangers 300 are connected by a refrigerant pipe 310.

[0074] When the air conditioning unit is cooling, the heat exchanger 300 in the indoor unit acts as the evaporator, and the heat exchanger in the outdoor unit acts as the condenser.

[0075] When the air conditioning unit is in heating mode, the heat exchanger 300 in the indoor unit acts as a condenser, and the heat exchanger in the outdoor unit acts as an evaporator.

[0076] The outer casing 100 of the air conditioning unit is a shell structure, and a first partition 120 and a second partition 130 are respectively arranged from top to bottom along the height direction of the outer casing 100.

[0077] Inside the outer casing 100, an air supply zone 101 is formed above the first partition 120, and an air outlet 110 is formed at the top of the air supply zone 101 for delivering the heat-exchanged airflow into the room.

[0078] A heat exchange zone 102 is formed between the first partition 120 and the second partition 130, and the heat exchanger 300 is installed in the heat exchange zone 102.

[0079] An equipment area 103 is formed below the second partition 130, and the compressor 200 is disposed in the equipment area 103.

[0080] Combination Figure 9 An air inlet is provided on the outer shell 100, which is connected to the heat exchange zone 102. The airflow is input into the heat exchange zone 102 from the air inlet. After heat exchange in the heat exchanger 300 in the heat exchange zone 102, the airflow is input into the air supply zone 101 through the air outlet on the first partition 120, and finally output to the room from the air outlet 110.

[0081] Air supply zone 101, heat exchange zone 102 and equipment zone 103 are arranged sequentially along the height of the outer shell 100 inside the outer shell 100. An air outlet is formed between the air supply zone 101 and the heat exchange zone 102. The air outlet 110 is located at the top of the outer shell 100 and the air inlet is located on the side wall of the outer shell 100. A fan is installed in the air supply zone 101. Under the action of the fan, the airflow input from the air inlet is heat-exchanged by the heat exchanger 300 and then output from the air outlet 110.

[0082] refer to Figure 4 , Figure 5 The heat exchanger 300 is fixed in the heat exchange zone 102 by the support assembly 400. The support assembly 400 includes a horizontal support member 410 and an inclined support member 420. The horizontal support member 410 is horizontally fixed at the bottom of the heat exchange zone 102, and the inclined support member 420 is connected to the horizontal support member 410 and is set at an angle to the horizontal support member 410.

[0083] The heat exchanger 300 is fixed on the inclined support 420 to achieve an angled arrangement of the heat exchanger 300 within the heat exchange zone 102.

[0084] In some embodiments of this application, the included angle β between the horizontal support 410 and the diagonal brace 420 satisfies: 0° < β < 90°.

[0085] The angle between the diagonal brace 420 and the horizontal support 410 is between 0° and 90°. The heat exchanger 300 is connected to the diagonal brace 420 so that the installation height of the heat exchanger 300 is less than the actual height of the heat exchanger 300. While ensuring the windward area of ​​the heat exchanger 300, the overall height of the outer shell 100 is reduced.

[0086] In some embodiments of this application, the horizontal support 410 and the diagonal brace 420 are both U-shaped frame structures, and the horizontal support 410 and the diagonal brace 420 are connected and fixed by the support cross section 440.

[0087] Both the horizontal support 410 and the diagonal brace 420 are frame structures. The horizontal support 410, the diagonal brace 420 and the support cross section 440 are pre-connected into one piece by welding or other mechanical connection, and then assembled in the heat exchange zone 102 to improve assembly efficiency and provide stable support for the heat exchanger 300.

[0088] In some embodiments of this application, reference is made to Figure 7 , Figure 8 The supporting horizontal part 440 includes a first supporting surface 442, a second supporting surface 443, and a support plate 441.

[0089] The first support surface 442 is inclinedly arranged at the bottom of the heat exchange zone 102, the second support surface 443 is connected at an angle to one side of the first support surface 442, and the support plate 441 is vertically arranged on the other side of the first support surface.

[0090] The bottom of the heat exchanger 300 is connected to the support plate 441. Therefore, the inclination angle of the support plate 441 relative to the bottom of the heat exchange zone 102 is complementary to the inclination angle of the heat exchange zone 102.

[0091] The inclination angle of the first support surface 442 relative to the bottom of the heat exchange zone 102 is equal to the inclination angle of the heat exchanger 300.

[0092] In other words, the support plate 441 is set perpendicular to the first support surface 442, the bottom of the heat exchanger 300 is supported on the support plate 441, and the windward and leeward sides of the heat exchanger 300 are parallel to the first support surface 442.

[0093] The first support surface 442, the second support surface 443, and the support plate 441 are integrally formed structures, which are formed by bending sheet metal steel and other materials. During bending, the first support surface 442 and the second support surface 443 are perpendicularly arranged, and the support plate 441 and the first support surface 442 are perpendicularly arranged.

[0094] Both the horizontal support 410 and the diagonal support 420 are hollow square tubes. The diagonal support 420 has a fixing hole 421. The heat exchanger 300 is fixed to the diagonal support 420 by means of fastening screws and other structures.

[0095] Specifically, an upper support is provided on the top of the heat exchanger 300, and upward-extending connecting bends are provided on both sides of the upper support. The diagonal brace 420 is connected and fixed to the connecting bends by fastening screws to achieve connection and fixation with the heat exchanger 300.

[0096] In some embodiments of this application, a lower bracket 340 is provided at the bottom of the heat exchanger 300, which is in contact with the support horizontal part 440. The heat exchanger 300 is connected and fixed to the support plate 441 through the lower bracket 340.

[0097] The lower support 340 has a support structure that is high in the middle and low at both ends. The lower support 340 includes a connecting area 341 and a support area 342 located on both sides of the connecting area 341. The height of the connecting area 341 is higher than that of the support area 342. The heat exchanger 300 is set on the connecting area 341, and the support area 342 is fixed on the support surface.

[0098] The heat exchanger 300 is fixed to the support plate 441 by the lower bracket 340. The bottom of the heat exchanger 300 is connected to the support area 342, which is higher than the connection area 341. When the heat exchanger 300 is working, some of the condensate on the surface of the heat exchanger 300 accumulates at the corner between the connection area 341 and the support area 342 on the outside of the heat exchanger 300. During the airflow from the windward side to the leeward side of the heat exchanger 300, due to the height difference between the support area 342 and the connection area 341, the condensate accumulated at the corner can be prevented from being output to the inner wall of the outer shell 100 with the airflow, thus avoiding any impact on the structural strength of the outer shell 100 and other working parts.

[0099] In other embodiments, reference is made to... Figure 4 To prevent airflow from being output from both sides of the heat exchanger 300, cover plates 330 are provided on both sides of the heat exchanger 300. The cover plates 330 extend to the inner wall of the outer shell 100, and a sealing strip can be provided between them and the inner wall of the outer shell 100 according to actual needs.

[0100] When connecting the cover plate 330, it is necessary to avoid interference with the refrigerant line 310 on the heat exchanger 300.

[0101] refer to Figure 10 In some embodiments of this application, a support stand 430 is also provided between the horizontal support member 410 and the diagonal support member 420.

[0102] The support upright 430 is used to improve the connection strength between the diagonal brace 420 and the horizontal support 410. At least two support uprights 430 are provided. The support uprights 430 are a certain distance away from the refrigerant pipeline 310 of the heat exchanger 300 to avoid interference with the refrigerant pipeline 310.

[0103] In some embodiments of this application, reference is made to Figure 6 , Figure 12 as well as Figure 13 A water collection tray 500 is also provided in the heat exchange zone 102. The water collection tray 500 is located below the heat exchanger 300 and is used to collect the condensate formed during the operation of the heat exchanger 300.

[0104] An insulation layer 550 is installed outside the water receiving pan 500 to reduce heat exchange between the water receiving pan 500 and the outside environment.

[0105] Combination Figure 4 The water receiving tray 500 is fixed to the bottom of the heat exchanger 102 on both sides by vertically set mounting plates 520.

[0106] Specifically, the bottom of the mounting plate 520 is provided with an outward bend, and the mounting plate 520 is fixed to the bottom of the heat exchanger 102 by the bend. The mounting plate 520 is fixed to the outer wall of the water receiving pan 500.

[0107] The horizontal support 410 and the support cross section 440 are connected inside the water receiving tray 500. The water receiving tray 500 includes a bottom wall 540 and a peripheral wall 530 surrounding the bottom wall 540. A drain pipe 510 is connected to the bottom of the water receiving tray 500.

[0108] Specifically, the support horizontal part 440 is supported on the water receiving tray 500 by the first support surface 442, and a gap is formed between the bottom of the second support surface 443 and the bottom of the water receiving tray 500 so that water at the bottom of the support horizontal part 440 can be output into the water receiving tray 500 through the gap.

[0109] A through drain hole 543 is provided on the bottom wall 540 of the water receiving tray 500. The drain hole 543 is connected to the drain pipe 510. The water receiving tray 500 is used to collect the condensate formed on the surface of the heat exchanger 300 during operation. The condensate collected in the water receiving tray 500 is discharged through the drain pipe 510.

[0110] In some embodiments of this application, the bottom wall 540 of the water receiving tray 500 includes a symmetrically arranged guide area 541 and a horizontal area 542. The guide area 541 is inclined downward along the direction close to the axis of symmetry of the water receiving tray 500 to drain the accumulated water in the water receiving tray 500. The horizontal area 542 is located outside the guide area 541 and is arranged horizontally to be connected to the support assembly 400.

[0111] The bottom of the support assembly 400 is installed in the horizontal area 542, and the two guide areas 541 on both sides form a V shape. The drain pipe 510 is connected to the lowest position of the bottom of the water receiving tray 500, that is, it is located in the middle of the two guide areas 541, so that the water in the water receiving tray 500 can be completely drained.

[0112] In some embodiments of this application, reference is made to Figure 10 , Figure 11 The heat exchanger 300 is connected to a refrigerant line 310, which is connected to the inner wall of the support assembly 400 and / or the housing 100 by fasteners 320.

[0113] In some embodiments of this application, the fastener 320 includes a fastening body 321, a bent portion 322, and a clamp portion 323. The bent portion 322 is formed at one end of the fastening body 321 and is set at an angle to the fastening body 321. The clamp portion 323 is detachably connected to the fastening body 321. The refrigerant pipeline 310 is connected to the fastening body 321 through the clamp portion 323. The bent portion 322 is detachably connected to the inner wall of the support assembly 400 and / or the outer casing 100.

[0114] During installation, first fix the refrigerant pipe 310 to the fastening body 321 using the clamp part 323, and then fix the bent part 322 to the support component 400 or the inner wall of the outer casing 100 using fastening screws to achieve the connection and fixation of the refrigerant pipe 310.

[0115] The clamp part 323 is specifically a ring structure formed by bending sheet metal, and the bending part 322 is a bend formed at one end of the fastening body 321. The angle between the bending part 322 and the fastening body 321 is determined according to the actual fixing position.
