Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0015] Please see Figures 1 to 6This utility model provides a same-side maintenance air conditioning unit, including a box-type unit frame 7, an electrical control box 3, a fan door mounting assembly 9, a fan door 5, a coil assembly 8, a compressor 20, a fan door fixing sheet metal part 13, and a G4 air filter 1. The electrical control box 3 is located on the inner windward side of the box-type unit frame 7, and the display screen 2 is located in the middle of the electrical control box 3. The fan door mounting assembly 9 and the fan door 5 are fixedly connected by a hinge 4 and a connecting rod lock 16. The fan door fixing sheet metal part 13 is located between the fan door mounting assembly 9 and the fan door 5. Between the fan doors 5, the fan door fixing sheet metal part 13 and the fan door 5 are locked together by the assembly 12. The fan door fixing sheet metal part 13 and the fan door mounting assembly 9 are locked together by two Torx screws 14. The coil assembly 8 is located on the inner air supply side of the box-type unit frame 7. The compressor 20 is located between the coil assembly 8 and the fan door mounting assembly 9. The G4 air filter 1 is located on the inner windward side of the box-type unit frame 7 and is also located on both sides of the electrical control box 3.

[0016] In this embodiment, the design makes it easy to directly observe and operate the electrical control box 3 and its display screen 2 from the windward side. At the same time, the fan door 5 is connected by hinges 4 and linkage locks 16, and with the tool-free fan door fixing sheet metal parts 13, the maintenance efficiency is greatly improved, the tools and operation time required for maintenance are reduced, and quick access to the unit for maintenance is achieved. The assembly 12 consists of two cross-slot recessed hexagonal head screws, a spring washer, and a flat washer.

[0017] Furthermore, the coil assembly 8 includes piping components and a coil. The piping components include a dryer filter tank, a sight glass, a liquid solenoid valve, an electronic expansion valve, a liquid pipe end, and an air pipe end. One end of the ball valve in the liquid pipe end is connected to a copper pipe, and the other end of the ball valve in the liquid pipe end is connected to the dryer filter through a copper pipe. The copper pipe is a copper pipe interface for connecting the indoor and outdoor units. Both ends of the sight glass are connected in parallel with the ball valve and the dryer filter through copper pipes. The dryer filter is connected to the liquid solenoid valve through a copper pipe. The liquid solenoid valve is connected to the electronic expansion valve through a copper pipe and is located at the inlet of the electronic expansion valve. The electronic expansion valve is connected to the liquid pipe end and the coil through a copper pipe. The outlet of the coil is the air pipe main. The air pipe main is connected to the ball valve in the air pipe end through a copper pipe. The end of the ball valve in the air pipe end away from the air pipe main is connected to a copper pipe, and this copper pipe is a copper pipe joint for connecting the indoor and outdoor units.

[0018] In this embodiment, the coil assembly 8 and its related liquid piping assemblies facilitate quick location and replacement of faulty components by maintenance personnel, reducing troubleshooting time. Simultaneously, the modular design of these components facilitates overall replacement and upgrades, improving system reliability and maintenance efficiency. Specifically, the ball valve functions as follows: it achieves rapid opening and closing by rotating 90 degrees, requiring only a small torque to achieve a tight seal; the sight glass allows for the determination of water content in the refrigerant by observing the color inside the lens; the dryer filter absorbs any moisture that may be present in the refrigerant, keeping it dry; the liquid circuit solenoid valve, in conjunction with the controller, uses electromagnetic force to drive the valve core, controlling the refrigerant's flow and opening degree; and the electronic expansion valve throttles the medium-temperature, high-pressure liquid refrigerant into a low-temperature, low-pressure liquid refrigerant.

[0019] Furthermore, the electrical control box 3 includes high-voltage components, low-voltage components, and a box body. A display screen 2 is provided on the door panel of the box body. Both the high-voltage components and the low-voltage components are located inside the box body, which is located on the inner windward side of the box-type unit frame 7.

[0020] In this embodiment, by installing high-voltage and low-voltage components inside the electrical control box 3 and displaying the working status and error information in real time on the display screen 2 on the door panel, maintenance personnel can quickly understand the system operation status, perform timely fault diagnosis and repair, and improve the maintainability and operational stability of the system.

[0021] Furthermore, a caster wheel 15 is provided on the side of the fan door 5 away from the hinge 4.

[0022] In this embodiment, by providing the caster wheel 15 on the fan door 5, the force on the fan door 5 during the opening and closing process is effectively distributed, preventing the hinge 4 from tilting and deforming due to excessive force, extending the service life of the equipment, improving the stability and smoothness of the opening and closing of the fan door 5, and further enhancing the convenience of maintenance.

[0023] Furthermore, the contact friction surfaces of the fan door 5 mounting frame and the universal wheel 15 are made of stainless steel plates, and the plates are set at an inclined angle.

[0024] In this embodiment, the purpose of using stainless steel sheet is to prevent the coating on the sheet from being rubbed off when the caster wheel 15 rubs against the sheet, which would cause the sheet to rust. The main reason for the inclined angle of the sheet is to prevent the hinge 4 from slightly tilting and deforming when the fan door 5 rotates out without the support provided by the caster wheel 15. The inclined angle of the parts ensures that the fan door 5 can still be opened and closed relatively easily when it is slightly tilted.

[0025] Furthermore, the fan door 5 comprises a fan, a fan bracket 11, and a fan screen 6.

[0026] In this embodiment, when maintenance is required, the connecting rod lock 16 is twisted to disengage the connecting rod from the connecting rod limiting hole, and the fan door 5 is rotated to a suitable position via the hinge, providing a passage to the interior of the wind wall unit for quick maintenance.

[0027] In this utility model, the compressor 20 is provided with a pipeline assembly, and the pipeline assembly is provided with a one-way valve, a solenoid valve, and a ball valve.

[0028] In this utility model, maintenance personnel first stand on the windward side of the box-type unit frame 7 and quickly understand the air conditioner's operating status and error messages by observing the display screen 2 located in the middle of the electrical control box 3. Subsequently, utilizing the connection design between the fan door mounting assembly 9 and the fan door 5 through the hinge 4 and connecting rod lock 16, and the tool-free disassembly screws (Phillips head screws, spring washers and flat washers assembly 12, and 38# M8 Torx screws 14) used between the fan door fixing sheet metal part 13 and the fan door 5 and fan door mounting assembly 9, disassembly can be quickly performed without carrying a large number of tools. Remove and open the fan door 5; after entering the unit, you can easily approach and inspect the coil assembly 8 and its liquid piping assembly (including the dryer filter tank, sight glass, etc.) located on the air supply side, as well as the compressor 20 and its piping assembly located between the coil assembly 8 and the fan door mounting assembly 9; at the same time, the G4 air filter 1 is located on both sides of the electrical control box 3, which is convenient for quick replacement and cleaning; during the opening and closing of the fan door 5, the caster wheel 15 and the contact friction surface made of stainless steel and set at an inclined angle ensure the smoothness and stability of the opening and closing of the fan door 5, further improving maintenance efficiency.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
