[0023] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0024] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides an air conditioning system to solve the problem that the room temperature is difficult to meet the user's actual needs. The following description will be provided in conjunction with the accompanying drawings.

[0027] Please see Figure 1 This application provides an air conditioning system, including a refrigerant supply system 1, a communication device 2, and a mobile air conditioning terminal 3. The communication device 2 includes a first communication mechanism 21 and a plurality of second communication mechanisms 22. The first communication mechanism 21 is disposed on the mobile air conditioning terminal 3, and the plurality of second communication mechanisms 22 are all disposed on the refrigerant supply system 1. When the mobile air conditioning terminal 3 is connected to the refrigerant supply system 1, the first communication mechanism 21 is connected to the second communication mechanism 22, so that the refrigerant of the mobile air conditioning terminal 3 is exchanged with the refrigerant of the refrigerant supply system 1.

[0028] The air conditioning system provided in this application embodiment, by setting up a refrigerant supply system 1, a mobile air conditioning terminal 3 and a connecting device 2, allows the mobile air conditioning terminal 3 to be connected to the refrigerant supply system 1 through the connecting device 2. This enables the refrigerant supply system 1 to continuously exchange refrigerant with the mobile air conditioning terminal 3 when the mobile air conditioning terminal 3 requires low-temperature refrigerant. This not only ensures that the refrigerant in the mobile air conditioning terminal 3 can meet the cooling requirements, but also enables the mobile air conditioning terminal 3 to perform continuous cooling for a long time, solving the problem that mobile air conditioners are difficult to achieve continuous cooling for a long time.

[0029] When the room temperature load is high, moving the portable air conditioner terminal 3 into the room can increase the room's cooling capacity. When the room temperature load is low, moving the portable air conditioner terminal 3 out of the room can reduce the room's cooling capacity, thus ensuring that the room's cooling capacity meets the user's needs and solving the problem that the room temperature is difficult to meet the user's actual needs.

[0030] Please see Figure 1 The refrigerant supply system 1 includes a first circulation loop and a second circulation loop. The first circulation loop includes a compressor 11, a condenser 12, a throttling device 13, an evaporator-condenser 14, and a cooling tower 15. The evaporator sides of the compressor 11, condenser 12, throttling device 13, and evaporator-condenser 14 are connected in sequence. The cooling tower 15 is connected to the condenser 12 to cool the condenser 12. The second circulation loop includes a third refrigerant pump 16 and multiple fixed air conditioning terminals 17. The third refrigerant pump 16, the condenser side of the evaporator-condenser 14, and the fixed air conditioning terminals 17 are connected in sequence. The refrigerant from the second circulation loop is input into each fixed air conditioning terminal 17 through the third refrigerant pump 16, enabling the refrigeration cycle of each fixed air conditioning terminal 17. In this embodiment, the refrigerant used in the second circulation loop and the mobile air conditioning terminal 3 is water.

[0031] Please see Figure 1 and Figure 3The portable air conditioning terminal 3 includes a refrigerant storage tank 31, a first refrigerant pump 32, a heat exchanger 33, a return air wall 34, a fan 35, and a power mechanism 36. The return air wall 34 is disposed on the refrigerant storage tank 31 and has at least one return air hole. The heat exchanger 33 is disposed on the return air wall 34, and the fan 35 is disposed on the heat exchanger 33. The first refrigerant pump 32 is disposed inside the refrigerant storage tank 31. The input end of the heat exchanger 33 is connected to the first refrigerant pump 32, and the output end of the heat exchanger 33 is connected to the refrigerant storage tank 31. In this embodiment, the heat exchanger 33 is an evaporative cooling grid. After the first refrigerant pump 32 delivers refrigerant to the evaporative cooling grid, the fan 35 drives the airflow to pass through the return air hole, the evaporative cooling grid, and the fan 35 in sequence. The airflow exchanges heat and cools down at the evaporative cooling grid, thereby causing the fan 35 to blow out low-temperature airflow to cool the room where the portable air conditioning terminal 3 is located.

[0032] Please see Figure 1 and Figure 3 The power mechanism 36 includes a power wheel 361, a first controller, and a temperature sensor 362. Both the power wheel 361 and the temperature sensor 362 are electrically connected to the first controller. The power wheel 361 is fixedly mounted on the bottom of the refrigerant storage tank 31. The first controller receives control signals and controls the rotation and direction of the power wheel 361 according to the control signals. The temperature sensor 362 is located on the inner wall of the refrigerant storage tank 31 and detects the temperature of the refrigerant inside the tank. When the temperature sensor 362 detects that the refrigerant temperature exceeds a preset value, the first controller controls the mobile air conditioning terminal 3 to move to the location of the refrigerant supply system 1 where the second communication mechanism 22 is provided, thereby facilitating the replenishment of low-temperature refrigerant to the mobile air conditioning terminal 3.

[0033] Please see Figure 1 and Figure 2The second connecting mechanism 22 includes a first connecting component 221 and a second connecting component 222. The first connecting component 221 includes a first winding member 2211, a first hose 2212, a second refrigerant pump 2213, and a one-way valve 2214. The second refrigerant pump 2213 and the one-way valve 2214 are both mounted on the first hose 2212. The second refrigerant pump 2213 is used to draw refrigerant from the refrigerant storage tank 31 into the refrigerant supply system 1, and the one-way valve 2214 is used to restrict the flow direction of the refrigerant. The first hose 2212 is connected to the input end of the condenser side of the evaporator-condenser 14. The first hose 2212 is wound on the first winding member 2211, which can wind the first hose 2212 to achieve the extension and retraction of the first hose 2212. The second connection assembly 222 includes a second winding member 2221, a second hose 2222, and a solenoid valve 2223. The solenoid valve 2223 is disposed on the second hose 2222. The second hose 2222 is connected to the output end of the third refrigerant pump 16. The second hose 2222 is wound on the second winding member 2221. The second winding member 2221 can wind the second hose 2222 to achieve the extension and retraction of the second hose 2222.

[0034] Please see Figure 2 and Figure 3 The refrigerant storage tank 31 has an injection port for the second hose 2222 to extend into and a discharge port for the first hose 2212 to extend into. By extending the first hose 2212 into the discharge port, the refrigerant in the refrigerant storage tank 31 can be drawn into the refrigerant supply system 1 by the second refrigerant pump 2213. By extending the second hose 2222 into the injection port, the refrigerant in the refrigerant supply system 1 can flow into the refrigerant storage tank 31 by opening the solenoid valve 2223.

[0035] Please see Figure 2 and Figure 3The first connecting mechanism 21 includes a second controller, a low liquid level sensor 212, and a high liquid level alarm buzzer 213. The second connecting component 222 also includes a normally open audible shut-off valve 223. The low liquid level sensor 212 is located on the side wall of the refrigerant storage tank 31 near the bottom wall of the refrigerant storage tank 31. The low liquid level sensor 212, the second refrigerant pump 2213, and the solenoid valve 2223 are all electrically connected to the second controller. During the process of the second refrigerant pump 2213 drawing refrigerant from the refrigerant storage tank 31 into the refrigerant supply system 1, if the low liquid level sensor 212 detects that the refrigerant level in the refrigerant storage tank 31 is lower than a preset value, the second controller controls the second refrigerant pump 2213 to shut down and the solenoid valve 2223 to open. During the opening of the solenoid valve 2223, if the high liquid level alarm buzzer 213 detects that the refrigerant liquid level in the refrigerant storage tank 31 is higher than the preset value, the high liquid level alarm buzzer 213 will emit a buzzing signal. The normally open sound-controlled shut-off valve 223 will close after detecting the buzzing signal to prevent refrigerant from overflowing from the refrigerant storage tank 31.

[0036] Please see Figure 2 and Figure 3 The first connecting mechanism 21 includes multiple first positioners 211, all of which are mounted on the fan 35. The second connecting mechanism 22 includes multiple second positioners 224, each corresponding to a first positioner 211. When the mobile air conditioning terminal 3 moves to the location of the refrigerant supply system 1 where the second connecting mechanism 22 is located, each of the first positioners 211 emits a laser signal. If each second positioner 224 receives the laser signal from its corresponding first positioner 211, the first connecting mechanism 21 connects to the second connecting mechanism 22. The first winding member 2211 controls the extension of the first hose 2212, and the second winding member 2221 controls the extension of the second hose 2222. Furthermore, the second connecting mechanism 22 also includes a first flow meter 225 and a second flow meter 226, both of which are electrically connected to a second controller. The first flow meter 225 is mounted on the first hose 2212, and the second flow meter 226 is mounted on the second hose 2222. The first flow meter 225 and the second flow meter 226 can help determine the refrigerant liquid level in the refrigerant storage tank 31, which is beneficial for the second controller to control the refrigerant liquid level in the refrigerant storage tank 31.
