[0026] The embodiment also includes first water storage tank 7, second water storage tank 13, third water storage tank 17, and a plurality of water pumps, a plurality of electromagnetic valves.The first water storage tank 7, the second water storage tank 13, the third water storage tank 17 are used to store water respectively, wherein:

[0027] The first water tank 7 has an outlet connected to the inlet of the first water pump 6 through a pipeline, the outlet of the first water pump 6 is connected to one end of the second flow channel of the plate evaporator 5 through a pipeline, and the other end of the second flow channel of the plate evaporator 5 is connected to an inlet of the first water tank through a pipeline, so that the first water tank 7, the first water pump 6 and the second flow channel of the plate evaporator 5 form a water circuit.

[0028] The first water tank 7 has an outlet connected to the inlet of the second water pump 8 through a pipeline, the outlet of the second water pump 8 is sequentially connected to an inlet of the third water tank 17 through the first electromagnetic valve 9 and the third electromagnetic valve 12, the third water tank 17 has an outlet sequentially connected to the inlet of the third water pump 10 through the sixth electromagnetic valve 16 and the fourth electromagnetic valve 14, and the outlet of the third water pump 10 is connected to an inlet of the first water tank 7 through a pipeline. Therefore, the first water tank 7, the second water pump 8, the first electromagnetic valve 9, the third electromagnetic valve 12, the third water tank 17, the sixth electromagnetic valve 16, the fourth electromagnetic valve 14 and the third water pump 10 form a water circuit.

[0029] A bypass pipeline is branched from the pipeline between the first electromagnetic valve 9 and the third electromagnetic valve 12 and connected to an inlet of the second water tank 13 through the second electromagnetic valve 11, and an outlet of the second water tank 13 is bypass connected to the pipeline between the sixth electromagnetic valve 16 and the fourth electromagnetic valve 14 through the fifth electromagnetic valve 15. Therefore, the first water tank 7, the second water pump 8, the first electromagnetic valve 9, the second electromagnetic valve 11, the second water tank 13, the fifth electromagnetic valve 15, the fourth electromagnetic valve 14 and the third water pump 10 form a water circuit.

[0030] A bypass pipeline is branched from the pipeline between the sixth electromagnetic valve 16 and the fourth electromagnetic valve 14 and connected to the inlet of the fourth water pump 19 through the seventh electromagnetic valve 18, the outlet of the fourth water pump 19 is connected to one end of the evaporative coil 23 through a pipeline, and the other end of the evaporative coil 23 is bypass connected to the pipeline between the first electromagnetic valve 9 and the third electromagnetic valve 12 through the eighth electromagnetic valve 27. Therefore, the third water tank 17, the sixth electromagnetic valve 16, the seventh electromagnetic valve 18, the fourth water pump 19, the evaporative coil 23, the eighth electromagnetic valve 27 and the third electromagnetic valve 12 form a water circuit.

[0031] In addition, the second water tank 13 also forms a water circuit with the evaporative coil 23 through the fifth electromagnetic valve 15, the seventh electromagnetic valve 18, the fourth water pump 19, the eighth electromagnetic valve 27 and the second electromagnetic valve 11.

[0032] The embodiment also includes a controller 26, which is electrically connected to the compressor 1, the condenser fan 2, the evaporative fan 22, all electromagnetic valves and all water pumps respectively. Temperature sensors are respectively installed in the first water tank 7, the second water tank 13 and the third water tank 17, and each temperature sensor is signal transmission electrically connected to the controller 26.

[0033] In this embodiment, the air conditioning device with cold storage uses R134a as refrigerant. The low-temperature and low-pressure gaseous refrigerant in the refrigeration system is sucked into the compressor 1 and compressed into high-temperature and high-pressure gas. The high-temperature and high-pressure gas is cooled into high-pressure liquid in the condenser 3 by the air sucked into the outdoor unit by the condenser fan 2. The high-pressure liquid is then divided into two paths. One path flows into the plate evaporator 5 after being throttled and depressurized by the first expansion valve 4. The low-pressure liquid refrigerant evaporates and absorbs the heat of the water in the plate evaporator 5. The water in the plate evaporator 5 is pumped from the first water storage tank 7 by the first water pump 6. The water in the first water storage tank 7 continuously flows through the first water pump 6, the plate evaporator 5, and then back to the first water storage tank 7. The water continuously releases heat and cools down in the plate evaporator 5, and the low-pressure liquid refrigerant absorbs the heat and becomes gaseous refrigerant. The other path flows into the copper tube sleeve fin evaporator 20 after being throttled and depressurized by the second expansion valve 21. The low-pressure liquid refrigerant evaporates and absorbs the heat of the indoor air evaporated by the indoor evaporator fan 22, which is sucked into the indoor unit. The indoor air is cooled and the humidity of the air is reduced. The gaseous refrigerant from the two paths is combined and then sucked into the compressor 1 again. This cycle is repeated to achieve the purpose of indoor cooling and dehumidification. At the same time, a small part of the cold energy of the air conditioning device continuously reduces the temperature of the water in the first water storage tank 7 to the required low temperature.

[0034] The controller 26 has a temperature sensor that can sense the temperature of the water in the first water storage tank 7. When the temperature of the water in the first water storage tank 7 reaches the required temperature (which can be set to any value between 2°C and 5°C), the controller 26 controls the first water pump 6 to stop working, the second water pump 8 to start working, and only the first electromagnetic valve 9 and the third electromagnetic valve 12 to open. The second water pump 8 pumps the low-temperature water in the first water storage tank 7 to the third water storage tank 17 (see Figure 2 ).

[0035] After the water in the first water storage tank 7 is pumped out, the controller 26 controls the third water pump 10 to start working, the second water pump 8 to stop working, and only the fifth electromagnetic valve 15 and the fourth electromagnetic valve 14 to open. The third water pump 10 pumps the normal-temperature water in the second water storage tank 13 to the first water storage tank 1 (see Figure 3 ).

[0036] After the first water storage tank 7 is filled with water, the third water pump 10 is closed, all electromagnetic valves are closed, and the first water pump 6 is started. The water in the first water storage tank 7 continuously flows through the first water pump 6, the plate evaporator 5, and then back to the first water storage tank 7. The water continuously releases heat and cools down in the plate evaporator 5. When the temperature of the water in the first water storage tank 7 reaches the required temperature (≤5°C), the first water pump 6 stops working (see Figure 1 .

[0037] If the water temperature in the third water tank 17 is not higher than 5°C, all the water pumps and electromagnetic valves of the air conditioning device are not operated. If the water temperature in the third water tank 13 is higher than 15°C, the controller 26 controls the first water pump 6 to stop working and the second water pump 8 to start working, and only the first electromagnetic valve 9 and the second electromagnetic valve 11 are opened. The second water pump 8 draws the low-temperature water in the first water tank 7 to the second water tank 13 for storage (see Figure 4 ).

[0038] When encountering super-high-temperature weather, the controller 26 detects the water level and temperature of the third water tank 17 and the second water tank 13. If it is found that only the water temperature in the third water tank 17 is low (≤5°C) and the water tank is full, the fourth water pump 19 is started, and only the third electromagnetic valve 12, the sixth electromagnetic valve 16, the eighth electromagnetic valve 27 and the seventh electromagnetic valve 18 are opened. The fourth water pump 19 draws the low-temperature water in the third water tank 17, flows through the evaporating coil 23, absorbs the heat of the air flowing through the evaporating coil 23 sucked by the indoor evaporating fan 22, cools the indoor air, and the heated water flows back to the third water tank 17, see Figure 5 .

[0039] If it is found that only the water temperature in the second water tank 13 is low (≤5°C) and the water tank is full, the fourth water pump 19 is started, and only the second electromagnetic valve 11, the seventh electromagnetic valve 18, the eighth electromagnetic valve 27 and the fifth electromagnetic valve 15 are opened. The fourth water pump 19 draws the low-temperature water in the second water tank 13, flows through the evaporating coil 23, absorbs the heat of the air flowing through the evaporating coil 23 sucked by the indoor evaporating fan 22, cools the indoor air, and the heated water flows back to the second water tank 13, see Figure 6 .

[0040] If it is found that only the water temperature in the third water tank 17 and the second water tank 13 is low (≤5°C) and the water tank is full, the fourth water pump 19 is started, and only the third electromagnetic valve 12, the sixth electromagnetic valve 16, the eighth electromagnetic valve 27 and the seventh electromagnetic valve 18 are opened. The fourth water pump 19 draws the low-temperature water in the third water tank 17, flows through the evaporating coil 23, absorbs the heat of the air flowing through the evaporating coil 23 sucked by the indoor evaporating fan 22, cools the indoor air, and the heated water flows back to the third water tank 17, see Figure 5 .

[0041] If the water in the second water tank 13 exceeds 15℃, the third water pump 10 is started, only the fifth electromagnetic valve 15 and the fourth electromagnetic valve 14 are opened, the third water pump 10 draws the water in the second water tank 13 to the first water tank 7, and participates in the heat exchange between the water and the refrigerant in the plate evaporator 5 again; if the water in the third water tank 17 exceeds 15℃, the third water pump 10 is started, only the sixth electromagnetic valve 16 and the fourth electromagnetic valve 14 are opened, the third water pump 10 draws the water in the third water tank 17 to the first water tank 7, and participates in the heat exchange between the water and the refrigerant in the plate evaporator 5 again. Only one of the first water tank 7, the second water tank 13 and the third water tank 17 is empty, so as to facilitate the circulation of cold water and hot water. See Figure 1 .

[0042] As shown in Figure 1 , because the copper pipe sleeve fin evaporator 20 has been cooling the indoor air, the low-temperature water in the evaporating coil 23 is also in heat exchange with the air flowing through the outer surface of the coil to cool down, so that the air conditioner can quickly cool the indoor air.
