The shell 312 is provided with a hot air inlet 301, a cold air outlet 302, a cold air inlet and a hot air outlet 303. Air with heat enters the air source heat pump unit 3 from the hot air inlet 301, and the temperature of the air is absorbed by the evaporator 306, and the cooled air is discharged from the cold air outlet 302. Similarly, air that needs to be heated enters the air source heat pump unit 3 from the cold air inlet, and the air is heated by the condenser 308, and the heated air is discharged from the hot air outlet 303.

[0029] The circulating pipeline one is used for connecting the hot air inlet 301 and the cold air outlet 302 of the air source heat pump unit 3 with the normal temperature static warehouse 2. Specifically, the circulating pipeline one includes a return air main pipe one 401, a plurality of return air branch pipes one 402, a supply air main pipe one 403 and a plurality of supply air branch pipes one 404.

Each supply air main pipe one 403 is connected with a plurality of supply air branch pipes one 404, and the plurality of supply air branch pipes one 404 are respectively inserted into the normal temperature static warehouse 2 from the plurality of air outlets three, and extend downward to the bottom of the wall along the wall of the normal temperature static warehouse 2. In this way, when the fan one 305 is started, the air in the normal temperature static warehouse 2 enters the air source heat pump unit 3 along the plurality of return air branch pipes one 402 and the return air main pipe one 401, and the air temperature is absorbed by the evaporator 306, and then returns to the normal temperature static warehouse 2 along the supply air main pipe one 403 and the plurality of supply air branch pipes one 404.

[0030] The circulating pipeline two is used for connecting the cold air inlet and the hot air outlet 303 of the air source heat pump unit 3 with the high temperature static warehouse 1. Specifically, the circulating pipeline two includes a return air main pipe two 501, a plurality of return air branch pipes two 502, a supply air main pipe two 503 and a plurality of supply air branch pipes two 504. The return air main pipe two 501 is arranged above the high temperature static warehouse 1, and the return air main pipe two 501 is connected with the cold air inlet 303. The plurality of return air branch pipes two 502 are connected with the return air main pipe two 501 at one end, and the other end of the plurality of return air branch pipes two 502 is respectively inserted into the high temperature static warehouse 1 from the plurality of air outlets two, and extends downward to the bottom of the shelf two 7 along the shelf two 7. The supply air main pipe two 503 is provided with two, and the two supply air main pipes two 503 are respectively arranged on the two sides of the return air main pipe two 501, and the two supply air main pipes two 503 are respectively connected with the two cold air inlets. Each supply air main pipe two 503 is connected with a plurality of supply air branch pipes two 504, and the plurality of supply air branch pipes two 504 are respectively inserted into the high temperature static warehouse 1 from the plurality of air outlets one, and extend downward to the bottom of the wall along the wall of the high temperature static warehouse 1. In this way, when the fan two 307 is started, the air in the normal temperature static warehouse 2 enters the air source heat pump unit 3 along the plurality of return air branch pipes two 502 and the return air main pipe two 501, and the air is heated by the condenser 308, and then returns to the high temperature static warehouse 1 along the supply air main pipe two 503 and the plurality of supply air branch pipes two 504.

[0031] In this embodiment, after the lithium battery is processed by the front end, it enters the shelf two 7 in the high-temperature static library 1. The temperature in the high-temperature static library 1 needs to be maintained at about 45°C, so that the lithium battery is fully aged. In this process, the high-temperature static library 1 needs to be continuously heated to maintain the temperature stable. After 2 days of static storage in the high-temperature static library 1, the lithium battery needs to be transferred from the high-temperature static library 1 to the normal-temperature static library 2 for short-term cooling for 6-8 hours, and then enters the capacity distribution cabinet for capacity distribution. After the capacity distribution is completed, the lithium battery is transferred into the normal-temperature static library 2 again for final static cooling. In this process, the lithium battery will release heat, which will cause the air temperature in the normal-temperature static library 2 to rise. In order to ensure the cooling of the lithium battery, the air in the normal-temperature static library 2 needs to be cooled to maintain the temperature stable. The method for maintaining the temperature stable of the high-temperature static library 1 and the normal-temperature static library 2 in this embodiment is as follows:

[0032] Start the fan one 305. The air in the normal-temperature static library 2 with a temperature higher than 25°C is transported to the evaporator 306 end of the air source heat pump unit 3 through the return air branch pipe one 402 and the return air main pipe one 401 under the driving of the fan one 305. The heat carrier evaporates and absorbs heat in the evaporator 306, so that the heat of the air is taken away and the air is cooled. The cooled air is transported into the normal-temperature static library 2 through the supply air main pipe one 403 and the supply air branch pipe one 404, so as to reduce the temperature in the normal-temperature static library 2 and maintain the temperature stable in the normal-temperature static library 2.

[0033] Start the fan two 307. The air in the high-temperature static library 1 with a temperature lower than 45°C is transported to the condenser 308 end of the air source heat pump unit 3 through the return air branch pipe two 502 and the return air main pipe two 501. The air with a temperature lower than 45°C is heated by the condenser 308. The heated air is transported into the high-temperature static library 1 through the supply air main pipe two 503 and the supply air branch pipe two 504, so as to maintain the temperature in the high-temperature static library 1. When the temperature of the air heated by the condenser 308 does not meet the environmental requirements of the high-temperature static library 1, start the electric heater 311 to compensate for the lack of heat.

[0034] When the heat provided by the normal-temperature static library 2 is higher than the heat required by the high-temperature static library 1, open the fan three 8 to introduce the outside air into the normal-temperature static library 2 to enhance the air flow, so as to reduce the temperature in the normal-temperature static library 2.

[0035] It should be noted that the heat generation of the lithium battery itself is small, mainly the high-temperature static heat and the capacity distribution heat. Under the action of the heat comprehensive utilization system in this embodiment, when the heat required by the high-temperature static library 1 and the heat released by the normal-temperature static library 2 cannot reach a balance, the temperature of the high-temperature static library 1 is taken as the standard.
