[0002] Air conditioning systems used in warehouses, pharmacies, and industrial settings are typically surface-mounted. In these environments, space constraints necessitate suspended installation, which requires multiple operators for application and maintenance, leading to inconvenience and risks of falling parts and injuries. This is especially true in spaces with a height of 1.8m-4.5m, where small to medium-sized units are widely used and installation and maintenance are usually done manually. However, suspended air conditioning systems require a significant number of support personnel for maintenance, necessitating disassembly of internal parts for inspection and repair. This results in low maintenance efficiency and wasted human resources. Utility Model Content
[0003] In view of this, the present invention provides an air conditioning fan cabinet that is easy to maintain and has a low profile, in order to solve the above problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An air conditioning unit with a low profile for easy maintenance includes: a housing, a fan assembly, a heat exchange device, a first panel, and a second panel. The heat exchange device is installed inside the housing. The top of the housing is a top sealing plate, the bottom is a bottom sealing plate, the left end is a control box side panel, the right end is a side panel, the rear end is an air inlet panel, and the front end is an air outlet panel. The first panel is vertically installed between the top sealing plate and the bottom sealing plate, and is parallel to the air inlet panel and the air outlet panel. The fan assembly is installed on the first panel. The second panel is located in the middle of the air inlet panel. One end of the second panel is hinged to the air inlet panel, and the other end is detachably bolted to the air inlet panel.
[0006] Furthermore, a motor panel is provided in the middle of the first panel. One end of the motor panel is hinged to the first panel, and the other end is detachably bolted to the first panel. The wind turbine device is installed on the motor panel.
[0007] Furthermore, the heat exchange device includes an evaporator, an expansion valve, and a circulation pipeline. The evaporator is mounted on the bottom sealing plate and located on the side of the motor panel near the air outlet panel. The circulation pipeline connects the evaporator and the outdoor unit. The expansion valve is mounted on the circulation pipeline and located inside the housing.
[0008] Furthermore, the heat exchange device also includes an evaporator water receiving tray, which is disposed at the bottom end of the evaporator.
[0009] Furthermore, the impeller device includes a motor and an impeller, the motor and the impeller are mounted on the motor panel, the output end of the motor is connected to the impeller in a drive connection, and the output end of the impeller is aligned with the evaporator.
[0010] Furthermore, it also includes a control box, which is installed on the inner wall of the side panel of the control box, and the motor is electrically connected to the control box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] See attached document Figure 1-5As shown, this utility model provides a low-profile air conditioning unit that is easy to maintain, comprising: a shell, a fan assembly, a heat exchange device, a first panel 40, and a second panel 50. The heat exchange device is installed inside the shell. The top of the shell is a top sealing plate 11, the bottom is a bottom sealing plate 12, the left end is a control box side panel 13, the right end is a side panel 14, the rear end is an air inlet panel 15, and the front end is an air outlet panel 16. The top sealing plate 11, the bottom sealing plate 12, the control box side panel 13, the side panel 14, the air inlet panel 15, and the air outlet panel 16 are connected by screws and nuts to form an integral sheet metal frame. The overall structure is compact, the appearance is flat, and it facilitates space utilization after installation. Insulation cotton is pasted on the inside of the box. The low-temperature cold air processed by the heat exchange device is insulated to prevent condensation from forming on the outside of the sheet metal due to temperature difference, thus eliminating the need to reserve operating space under the equipment. The first panel 40 is vertically installed between the top sealing plate 11 and the bottom sealing plate 12, and is parallel to the air inlet panel 15 and the air outlet panel 16. The impeller is installed on the first panel 40. The second panel 50 is in the middle of the air inlet panel 15. One end of the second panel 50 is hinged to the air inlet panel 15 by a fixed hinge or hinge. The second panel 50 forms a rotatable structure on the air inlet panel 15. The other end is detachably bolted to the air inlet panel 15. When the bolt is removed, the second panel 50 can be rotated open for inspection and maintenance.
[0025] In a preferred embodiment, a motor panel 41 is provided in the first panel 40, wherein one end of the motor panel 41 is hinged to the first panel 40 by a fixed hinge or hinge, and the motor panel 41 forms a rotatable structure on the first panel 40, and the other end is detachably bolted to the first panel 40. The impeller device is installed on the motor panel 41. When the bolt is removed, the second panel 50 is rotated open, and the motor panel 41 carrying the impeller device on the first panel 40 is rotated open, so that inspection and maintenance can be carried out.
[0026] In a preferred embodiment, the heat exchange device includes an evaporator 31, an expansion valve 32, and a circulation pipe 33. The evaporator 31 is mounted on the bottom sealing plate 12 and is a finned heat exchanger located on the side of the motor panel 41 near the air outlet panel 16. The circulation pipe 33 connects the evaporator 31 and the outdoor unit. The expansion valve 32 is mounted on the circulation pipe 33 and located inside the housing. The circulation pipe 33 connects to the matching air-cooled outdoor unit and uses the compressor as power to force the refrigerant to circulate. It connects the evaporator 31 and the expansion valve 32 inside the housing through the side panel 14 and connecting pipes. After being compressed by the compressor and condensed by the outdoor condenser, the refrigerant enters the housing on the indoor side. The refrigeration cycle is throttled and depressurized by the expansion valve 32, enters the evaporator 31 for heat absorption and evaporation, and then returns to the air-cooled outdoor unit through the side panel 14, completing the refrigerant cycle.
[0027] The indoor air, i.e. the air from the application side, enters the casing for air circulation, heat exchange, and cooling. The indoor air enters through the air inlet filter 51 on the air inlet panel 15, and then passes through the motor 21 and the impeller 22. It reaches the heat exchanger side of the evaporator 31 and exchanges heat with the refrigerant in the copper tubes of the heat exchanger. The heat in the air is cooled by the refrigerant in the evaporator 31, and then the air is discharged through the air outlet louvers 161, sending the cool air to the indoor environment, thus completing one air handling cycle.
[0028] In a preferred embodiment, the heat exchange device further includes an evaporator water receiving pan 34, which is located at the bottom of the evaporator 31.

The control box 60 is installed on the inner wall of the side panel 13 of the control box. The connection between the motor 21 and the control box 60 uses a corrugated connecting cable to eliminate the influence of the motor panel 41's rotation on the electrical connection. The control box 60 is also equipped with a temperature sensor and a control display screen. The control elements within the control box 60 compare and perform logical operations with the control program, outputting signals to control the air conditioning unit. The control box 60 has reserved interfaces for single-unit and multi-unit connections, enabling independent and cluster control.
[0031] In a preferred embodiment, an air inlet filter 51 is provided on the second panel 50, and an air outlet louver 161 is provided on the air outlet panel 16. The air inlet filter 51, the evaporator 31, and the air outlet louver 161 are arranged in parallel to each other.
[0032] In a preferred embodiment, a hanging bracket 70 is provided at the top of the outer side wall of the air inlet panel 15 and the air outlet panel 16.
