This embodiment discloses an air-conditioning device, which includes a first air-conditioning machine 1 and a cabinet 2, wherein the first air-conditioning machine 1 and the cabinet 2 are both independently arranged, and the first air-conditioning machine 1 includes a first shell 11 and an evaporator, and the evaporator is arranged in the first shell 11; or the first air-conditioning machine 1 also includes a first fan 12, and the first fan 12 is also arranged in the first shell 11.

[0030] In addition, two first fans 12 are provided, and the first air conditioner 1 also includes an installation partition 13. The first shell 11 is provided with a cavity 110. The installation partition 13 is arranged in the cavity 110. The installation partition 13 is used to limit the installation of the two first fans 12. The two first fans 12 are respectively arranged on both sides of the installation partition 13. The installation partition 13 and the first shell 11 jointly limit the installation of the two first fans 12. In this way, by setting two first fans 12, the air volume of the first air conditioner 1 can be increased, thereby improving the heat exchange efficiency.

[0031] The evaporator is arranged in the first shell 11 and is located on one side of the first fan 12. The indoor return air first flows through the first fan 12 and then enters the evaporator for heat exchange. After the heat exchange, the indoor return air is cooled and then sent back to the room.

[0032] In addition, the air-conditioning device of this embodiment may also include a second air-conditioner, wherein the second air-conditioner is also independently arranged, and the second air-conditioner is connected to the first air-conditioner 1 through the cabinet 2, so as to realize the evaporation-condensation refrigeration cycle; generally, the first air-conditioner 1 and the cabinet 2 are installed indoors, and the second air-conditioner is installed outdoors. The first air-conditioner 1 and the cabinet 2 can be pre-installed in the factory, and when installing on site, the second air-conditioner can be connected to the pipe assembly of the cabinet 2.

[0033] The second air conditioner includes a second shell and a condenser, or the second air conditioner also includes a second fan, the condenser is arranged in the second shell, the second fan can be arranged in the second shell or on the second shell, and the second fan is used to allow outdoor air to flow through the condenser, thereby dissipating heat from the refrigerant in the condenser.

[0034] The cabinet 2 includes a cabinet body 21, in which a compressor 23 and a first pipe assembly 22 are arranged. The first pipe assembly 22 partially passes through the cabinet body 21, and the compressor 23 is connected to the evaporator of the first air conditioner 1 and the condenser of the second air conditioner through the first pipe assembly 22.

[0035] In this embodiment, the cabinet 2 is arranged on the outside of the first shell 11, so that when the first fan 12 is disassembled and repaired, the first fan 12 will not damage the pipeline or other components, thereby ensuring that the refrigerant in the pipeline will not leak, facilitating the maintenance of the first fan 12.

[0036] A compressor 23 and a first pipeline assembly 22 are provided in the cabinet 2 of the present embodiment, so that the cabinet 2 forms a modular pipeline system. When the first pipeline assembly 22 leaks, it can be maintained separately, thereby preventing the refrigerant in the first pipeline assembly 22 from leaking into the interior of the first air conditioner 1 and affecting the performance of the evaporator, reducing the impact of the leakage of the first pipeline assembly 22 on the air conditioner or the server in the computer room, and improving the application reliability of the air-conditioning device. In addition, the compressor 23 and the first pipeline assembly 22 are both arranged in the cabinet 2, which reduces the size of the air-conditioning device, thereby reducing the occupied area of ​​the air-conditioning device and improving the applicability of the air-conditioning device.

[0037] Reference Figure 2 As shown, the first pipeline assembly 22 includes a first pipeline 220 and a second pipeline 221. The first end of the first pipeline 220 is connected to the air inlet end of the compressor 23, and the second end of the first pipeline 220 passes through the cabinet 21 and penetrates into the first shell 11 to be connected to the evaporator. The first end of the second pipeline 221 is connected to the exhaust end of the compressor 23, and the second end of the second pipeline 221 passes through the cabinet 21. When the second air conditioner needs to be used, the second end of the second pipeline 221 can be connected to the condenser of the second air conditioner.

[0038] The cabinet 2 is also provided with a second pipeline assembly 27 and a throttling device 24. The second pipeline assembly 27 includes a third pipeline 270 and a fourth pipeline 271. The first end of the third pipeline 270 is connected to the outlet end of the throttling device 24, and the second end of the third pipeline 270 passes through the cabinet 21 and enters the first shell 11 to be connected to the evaporator. The first end of the fourth pipeline 271 is connected to the inlet end of the throttling device 24, and the second end of the fourth pipeline 271 passes through the cabinet 21 and is connected to the condenser. When the second air conditioner needs to be used, the second end of the fourth pipeline 271 is connected to the condenser of the second air conditioner.

[0039] In this embodiment, the second end of the first pipeline 220 and the second end of the third pipeline 270 are respectively located at the lower part of the same side of the cabinet 21, which facilitates the connection between the compressor 23 and the throttling device 24 and the evaporator of the first air conditioner 1. The second end of the second pipeline 221 and the second end of the fourth pipeline 271 are respectively located at the top of the cabinet 21, which facilitates the connection between the compressor 23 and the throttling device 24 and the condenser of the second air conditioner.

[0040] Reference Figure 2 As shown, a filter dryer 25 and a sight glass 26 are also provided in the cabinet 21. The filter dryer 25 is connected to the fourth pipeline 271. The filter dryer 25 is used to absorb moisture in the system and filter out impurities in the refrigerant in the fourth pipeline 271 to prevent blockage in the pipeline, thereby ensuring the smooth flow of the throttling device 24 and the normal operation of the system. The sight glass 26 is connected to the fourth pipeline 271 and is located between the filter 25 and the throttling device 24. The sight glass 26 is used to detect the refrigerant filling condition in the fourth pipeline 271. If the refrigerant is not filled sufficiently, there will be bubbles, so as to prevent the normal operation of the air-conditioning device from being affected by insufficient filling.

[0041] In a specific application scenario, when the air-conditioning device is working, the low-temperature and low-pressure refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor 23, enters the condenser through the second pipeline 221, condenses and releases heat in the condenser to form a high-temperature and high-pressure liquid refrigerant, and then flows into the throttling device 24 through the fourth pipeline 271. After being throttled into a low-temperature and low-pressure liquid refrigerant by the throttling device 24, it enters the evaporator through the third pipeline 270, evaporates and absorbs heat in the evaporator to form a low-temperature and low-pressure gaseous refrigerant, and then returns to the compressor 23 through the first pipeline 220, and the cycle is repeated.

[0042] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
