Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to an air conditioning system, a control method for an air conditioning system, a control device for an air conditioning system, and a computer-readable storage medium. Background Art

[0002] Currently, as the scale of data centers is getting larger and larger, the heat generation of data centers is also increasing. In related technologies, row coolers are provided in data centers for heat dissipation. Usually, the row coolers are provided with two sets of heat dissipation systems, a liquid cooling system and an air cooling system, according to requirements. The two sets of heat dissipation systems each bear a part of the heat dissipation requirements in the data center. For example, a liquid cooling solution can be used to cool components such as servers, and an air cooling solution can be used to cool components such as hard disks.

[0003] However, since the two heat dissipation systems with different heat dissipation principles have different working principles and working states, they usually need to be independently configured, deployed, and regulated, thereby increasing costs and reducing the overall heat dissipation efficiency of the row cooler. Summary of the Invention

[0004] Embodiments of the present invention provide an air conditioning system, a control method for an air conditioning system, a control device for an air conditioning system, and a computer-readable storage medium to solve at least one of the above-mentioned technical problems.

[0005] An air conditioning system provided by an embodiment of the present invention includes a heat exchange member, a liquid cooling system, and an air cooling system. The liquid cooling system and the air cooling system are connected through the heat exchange member. One of the liquid cooling system and the air cooling system provides heat or cold to the other through the heat exchange member. The air conditioning system is configured to control the liquid cooling system and the air cooling system to perform thermal management on the load according to the demand state of the load and the ambient temperature.

[0006] In this way, the liquid cooling system and the air cooling system are connected using a heat exchange member, so that the liquid cooling system and the air cooling system can share a set of refrigeration and heating devices, thereby saving costs compared to the independent configuration and deployment of the liquid cooling system and the air cooling system. Moreover, the air cooling system and the liquid cooling system can simultaneously perform thermal management on the load, improving the overall heat dissipation efficiency of the air conditioner.

[0007] In some embodiments, the air cooling system includes a first heat exchanger, the liquid cooling system includes a second heat exchanger. The air cooling system is configured to refrigerate and heat the first heat exchanger and the heat exchange member. The liquid cooling system obtains the heat or cold of the air cooling system through the heat exchange member, and uses the heat or cold of the air cooling system to heat or cool the second heat exchanger.

[0008] In this way, by setting the air-cooling system to cool and heat the first heat exchanger and the heat exchange component, the air-cooling system can provide heat or cold to the liquid-cooling system. The liquid-cooling system does not need to be equipped with additional cooling and heating components, which can save costs. Moreover, the air-cooling system and the liquid-cooling system can simultaneously perform thermal management on the data center, improving the overall heat dissipation efficiency of the air conditioner.

[0009] In some embodiments, the air-cooling system includes a compressor assembly, a four-way valve, a third heat exchanger, a power assembly, a solenoid valve, a first electronic expansion valve, and a second electronic expansion valve. The compressor assembly is respectively connected to the third heat exchanger and the first heat exchanger through the four-way valve. The third heat exchanger is connected to the power assembly and the solenoid valve, and the power assembly and the solenoid valve are arranged in parallel; the power assembly and the solenoid valve are connected to the heat exchange component through the first electronic expansion valve, and the power assembly and the solenoid valve are connected to the first heat exchanger through the second electronic expansion valve. The air-conditioning system is configured to control at least one of the compressor assembly and the power assembly to provide heat or cold to the first heat exchanger and the heat exchange component according to the demand state of the load and the ambient temperature; the liquid-cooling system includes a water pump, and the outlet of the water pump communicates with the inlet of the second heat exchanger through the heat exchange component, and the outlet of the second heat exchanger communicates with the inlet of the water pump.

[0010] In this way, by arranging the compressor assembly and the power assembly in the air-cooling system, the air-cooling system can provide heat or cold to the first heat exchanger and the heat exchange component, and the liquid-cooling system is provided with a water pump, which can pump the cooling water to the heat exchange component for heat exchange and then enter the second heat exchanger. Thus, the air-cooling system and the liquid-cooling system can cooperate to perform thermal management on the load.

[0011] In some embodiments, the power assembly includes a first valve, a second valve, and a fluorine pump. The third heat exchanger communicates with the fluorine pump through the first valve. The fluorine pump communicates with the heat exchange component through the second valve and the first electronic expansion valve, and the fluorine pump communicates with the first heat exchanger through the second valve and the second electronic expansion valve. The first valve and the second valve are configured to control the fluorine pump to provide heat or cold to the first heat exchanger and the heat exchange component.

[0012] In this way, by arranging the first valve and the second valve at both ends of the fluorine pump, the power assembly can be controlled to provide heat or cold to the first heat exchanger and the heat exchange component according to different demand states of the load.

[0013] In some embodiments, the compressor assembly includes a compressor, a gas-liquid separator, and a first check valve. The outlet of the compressor communicates with the four-way valve. The inlet of the gas-liquid separator communicates with the first heat exchanger through the four-way valve. The outlet of the gas-liquid separator communicates with the four-way valve through the first check valve. The outlet of the gas-liquid separator communicates with the inlet of the compressor.

[0014] Thus, by providing a first check valve between the gas-liquid separator and the compressor, and the first check valve can communicate the gas-liquid separator with the four-way valve, so that the refrigerant can flow from the first check valve into the four-way valve, which can reduce the operation of the compressor and lower the energy consumption.

[0015] In some embodiments, the air-cooling system includes a compressor assembly, a third heat exchanger, a power assembly, a second check valve, a first electronic expansion valve, and a second electronic expansion valve. The compressor assembly is respectively connected to the third heat exchanger and the first heat exchanger through the four-way valve. The third heat exchanger is connected to the power assembly and the second check valve. The power assembly and the second check valve are arranged in parallel; the power assembly and the second check valve are connected to the heat exchange element through the first electronic expansion valve, and the power assembly and the second check valve are connected to the first heat exchanger through the second electronic expansion valve. The air-conditioning system is configured to control at least one of the compressor assembly and the power assembly to provide heat or cold to the first heat exchanger and the heat exchange element according to the demand state of the load and the ambient temperature; the liquid-cooling system includes a water pump. The outlet of the water pump communicates with the inlet of the second heat exchanger through the heat exchange element, and the outlet of the second heat exchanger communicates with the inlet of the water pump.

[0016] Thus, by providing a compressor assembly and a power assembly in the air-cooling system, the air-cooling system can provide heat or cold to the first heat exchanger and the heat exchange element, and the liquid-cooling system is provided with a water pump, which can provide the driving force for the cooling water to flow, so that the cooling water flows through the heat exchange element for heat exchange and then enters the second heat exchanger, so that the air-cooling system and the liquid-cooling system can cooperate to perform thermal management on the load.

[0017] In some embodiments, the compressor assembly includes a compressor, a gas-liquid separator, and a first check valve. The outlet of the compressor communicates with the third heat exchanger. The inlet of the gas-liquid separator communicates with the first heat exchanger. The outlet of the gas-liquid separator communicates with the third heat exchanger through the first check valve. The outlet of the gas-liquid separator communicates with the inlet of the compressor. The first check valve is arranged in parallel with the compressor.

[0018] Thus, by providing a first one-way valve between the gas-liquid separator and the compressor, and the first one-way valve being capable of connecting the gas-liquid separator and the third heat exchanger, the refrigerant can flow from the first one-way valve into the third heat exchanger, which can reduce the operation of the compressor and lower the energy consumption.

[0019] In some embodiments, the air-conditioning system includes an indoor fan and an electric heating element, the electric heating element is disposed at the air outlet of the indoor fan, and the air-conditioning system is configured to: when the load is in a heating demand state, control the air-cooling system and the liquid-cooling system to be turned off, and control the electric heating element and the indoor fan to be started, so that the electric heating element heats the air flow blown by the indoor fan to the load.

[0020] Thus, when the load needs heating and the air-cooling system and the liquid-cooling system are unable to provide heat to the load, by starting the electric heating element and the indoor fan, when the indoor fan blows air to the load, the electric heating element can heat the air flow, and thus heat can be provided to the load.

[0021] In some embodiments, when the indoor temperature of the load is less than a first preset temperature, it is determined that the demand state of the load is a heating demand state; when the indoor temperature of the load is less than or equal to a second preset temperature and greater than or equal to the first preset temperature, it is determined that the demand state of the load is a standby state; when the indoor temperature of the load is greater than the second preset temperature, it is determined that the demand state of the load is a heat dissipation demand state; the first preset temperature is less than the second preset temperature.

[0022] Thus, by comparing the indoor temperature of the load with the preset temperature, the demand state of the load can be accurately understood, so as to dissipate heat and heat the load in a timely manner.

[0023] In some embodiments, the air-cooling system includes a compressor assembly, a power assembly and a first heat exchanger, the liquid-cooling system includes a second heat exchanger, and the air-conditioning system is configured to: when the load is in a heat dissipation demand state and a first outdoor ambient temperature, control the compressor assembly to provide cooling capacity to the first heat exchanger and the heat exchange element, so that the heat exchange element provides cooling capacity to the second heat exchanger; when the load is in a heat dissipation demand state and a second outdoor ambient temperature, control the compressor assembly and the power assembly to provide cooling capacity to the first heat exchanger and the heat exchange element, so that the heat exchange element provides cooling capacity to the second heat exchanger; when the load is in a heat dissipation demand state and a third outdoor ambient temperature, control the power assembly to provide cooling capacity to the first heat exchanger and the heat exchange element, so that the heat exchange element provides cooling capacity to the second heat exchanger; the magnitudes of the first outdoor ambient temperature, the second outdoor ambient temperature and the third outdoor ambient temperature decrease in sequence.

[0024] In this way, the outdoor temperature is used to control at least one of the compressor assembly and the power assembly to provide cooling capacity to the heat exchanger and the second heat exchanger, so that different components can be selected to provide cooling capacity according to different temperature conditions, ensuring the heat dissipation efficiency while saving energy consumption.

[0025] In some embodiments, the air-cooling system includes a compressor assembly, a power assembly, and a first heat exchanger, the liquid-cooling system includes a second heat exchanger, and the air-conditioning system is configured to: when the load is in a heating demand state, control the compressor assembly to supply heat to the first heat exchanger and the heat exchanger, so that the heat exchanger provides heat to the second heat exchanger.

[0026] In this way, the compressor assembly is controlled to supply heat to the first heat exchanger and the heat exchanger according to the indoor temperature of the load, so that the load can be heated when the indoor temperature is low, improving the operating efficiency of the load.

[0027] A control method for an air-conditioning system provided by an embodiment of the present invention. The air-conditioning system includes a heat exchanger, a liquid-cooling system, and an air-cooling system. The liquid-cooling system and the air-cooling system are connected through the heat exchanger.

The control method includes obtaining the demand state and ambient temperature of the load; controlling the liquid-cooling system and the air-cooling system to perform thermal management on the load according to the demand state and ambient temperature of the load.

[0028] In this way, the heat exchanger is used to connect the liquid-cooling system and the air-cooling system, so that the liquid-cooling system and the air-cooling system can share a set of refrigeration and heating devices, thus saving costs compared with the independent configuration and deployment of the liquid-cooling system and the air-cooling system, and the air-cooling system and the liquid-cooling system can simultaneously perform thermal management on the air conditioner, improving the overall heat dissipation efficiency of the air conditioner.

[0029] In some embodiments, the air-cooling system includes a compressor assembly, a power assembly, and a first heat exchanger, and the liquid-cooling system includes a second heat exchanger. Controlling the liquid-cooling system and the air-cooling system to perform thermal management on the load according to the demand state of the load and the ambient temperature includes, when the load is in a heat dissipation demand state and a first outdoor ambient temperature, controlling the compressor assembly to provide cooling capacity to the first heat exchanger and the heat exchange member, so that the heat exchange member provides cooling capacity to the second heat exchanger; when the load is in a heat dissipation demand state and a second outdoor ambient temperature, controlling the compressor assembly and the power assembly to provide cooling capacity to the first heat exchanger and the heat exchange member, so that the heat exchange member provides cooling capacity to the second heat exchanger; when the load is in a heat dissipation demand state and a third outdoor ambient temperature, controlling the power assembly to provide cooling capacity to the first heat exchanger and the heat exchange member, so that the heat exchange member provides cooling capacity to the second heat exchanger.

[0030] In this way, at least one of the compressor assembly and the power assembly is controlled according to the outdoor temperature of the load to provide cooling capacity to the heat exchange member and the second heat exchanger, so that different components can be selected to provide cooling capacity according to different temperature conditions, which can ensure the heat dissipation efficiency while saving energy consumption.

[0053] Please refer to Figures 1 to 5 , an air conditioning system 100 provided by an embodiment of the present invention includes a heat exchange member 10, a liquid cooling system 30 and an air cooling system 20. The liquid cooling system 30 and the air cooling system 20 are connected through the heat exchange member 10. One of the liquid cooling system 30 and the air cooling system 20 provides heat or cold to the other through the heat exchange member 10. The air conditioning system 100 is configured to control the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000 according to the demand state of the load 1000 and the ambient temperature.

[0054] In this way, the liquid cooling system 30 and the air cooling system 20 are connected by using the heat exchange member 10, so that the liquid cooling system 30 and the air cooling system 20 can share a set of refrigeration and heating devices, thereby saving costs compared with the independent configuration and deployment of the liquid cooling system 30 and the air cooling system 20, and the air cooling system 20 and the liquid cooling system 30 can simultaneously perform thermal management on the air conditioner, improving the overall heat dissipation efficiency of the air conditioner.

[0055] Among them, according to Figure 1As shown, the load 1000 includes, but is not limited to, components of a data center, and the components of the data center include, but are not limited to, servers 500 and storage devices 600, etc. A data center is a building site that centrally places electronic information devices and provides an operating environment for them. A large number of servers 500 and storage devices 600 are centrally placed in the data center, which can provide powerful data storage and processing capabilities. Since the servers 500 and storage devices 600 need to release heat during operation, the indoor temperature of the load 1000 rises. Excessive indoor temperature is likely to cause faults such as thermal runaway in the load 1000. Therefore, an air-conditioning system 100 is provided in the load 1000 to dissipate heat from the servers 500 and storage devices 600.

[0056] Specifically, the air-conditioning system 100 includes a heat exchanger 10, a liquid cooling system 30, and an air cooling system 20. Among them, the liquid cooling system 30 can utilize the high thermal conductivity and high heat capacity characteristics of the liquid to absorb and transfer heat through the circulating coolant, thereby achieving heat dissipation for the heat-generating components. For example, the liquid cooling system 30 can indirectly dissipate heat from the server 500 through a heat transfer medium such as a liquid cooling plate. By circulating the coolant inside the liquid cooling plate, the heat of the server 500 can be transferred to the coolant through the liquid cooling plate, so as to achieve the purpose of reducing the temperature of the server 500.

[0057] The air cooling system 20 is a heat dissipation system that uses air as a cooling medium to reduce the temperature of heat-generating components through gas convection. The air cooling system 20 can achieve a reduction in the temperature of the heat-generating components through the circulation and phase change of the refrigerant. For example. The air cooling system 20 can release heat from the high-temperature and high-pressure gaseous refrigerant in the third heat exchanger 24 to become a liquid refrigerant. When the liquid refrigerant flows through the periphery of the storage device 600, it can absorb the heat of the air and become a gaseous state, so that the air temperature on the periphery of the storage device 600 is reduced, and the cold air is blown towards the storage device 600 by a fan to achieve the purpose of reducing the temperature of the energy storage device.

[0058] The liquid cooling system 30 and the air cooling system 20 can be connected through the heat exchanger 10. Among them, the heat exchanger 10 is a heat exchange device that can exchange heat between the liquid cooling system 30 and the air cooling system 20. For example, the heat exchanger 10 can be a plate heat exchanger. By stacking metal sheets with a certain corrugated shape, thin rectangular channels are formed between various plates, so that the refrigerant and the coolant exchange heat through the plates when flowing through the channels.

[0059] One of the liquid cooling system 30 and the air cooling system 20 provides heat or cold to the other through the heat exchanger 10. For example, when components capable of heating and refrigerating are provided on the liquid cooling system 30, the liquid cooling system 30 can provide heat or cold to the air cooling system 20 through the heat exchanger 10; or when components capable of heating and refrigerating are provided on the liquid cooling system 30, the air cooling system 20 can provide heat or cold to the liquid cooling system 30 through the heat exchanger 10. In this application, the example of the air cooling system 20 providing heat or cold to the liquid cooling system 30 through the heat exchanger 10 is used for illustration.

[0060] According to the demand state of the load 1000 and the ambient temperature, the air conditioning system 100 can control the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000. The demand state of the load 1000 includes a heating demand state and a heat dissipation demand state. The ambient temperature includes the indoor ambient temperature of the load 1000 and the outdoor ambient temperature of the load 1000. Among them, the indoor ambient temperature can determine whether the air conditioning system 100 starts and the demand state of the load 1000. The outdoor ambient temperature can determine the heat dissipation mode selected by the air cooling system 20 in the heat dissipation demand state.

[0061] Please refer to Figures 2 to 5 , in some embodiments, the air cooling system 20 includes a first heat exchanger 21, the liquid cooling system 30 includes a second heat exchanger 31, the air cooling system 20 is configured to cool and heat the first heat exchanger 21 and the heat exchanger 10, and the liquid cooling system 30 obtains the heat or cold of the air cooling system 20 through the heat exchanger 10 and uses the heat or cold of the air cooling system 20 to heat or cool the second heat exchanger 31.

[0062] In this way, by setting the air cooling system 20 to cool and heat the first heat exchanger 21 and the heat exchanger 10, the air cooling system 20 can provide heat or cold to the liquid cooling system 30. The liquid cooling system 30 does not need to be configured with additional refrigerating and heating components, which can save costs, and the air cooling system 20 and the liquid cooling system 30 can simultaneously perform thermal management on the load 1000, improving the overall heat dissipation efficiency of the air conditioner.

[0063] Specifically, the air-cooling system 20 includes a first heat exchanger 21, and the liquid-cooling system 30 includes a second heat exchanger 31. The first heat exchanger 21 and the second heat exchanger 31 may be cold plates. Among them, the first heat exchanger 21 is disposed on one side of the storage device 600 and can perform heat exchange on the storage device 600; the second heat exchanger 31 is disposed on one side of the server 500 and can perform heat exchange on the server 500. The heat or cold generated by the air-cooling system 20 can be transferred to the first heat exchanger 21 and the heat exchange member 10, so that the first heat exchanger 21 can heat or cool the storage device 600, and the liquid-cooling system 30 can obtain the heat or cold generated by the air-cooling system 20 through the heat exchange member 10 and transfer the heat or cold of the air-cooling system 20 to the second heat exchanger 31, so that the second heat exchanger 31 can heat or cool the server 500.

[0064] Please refer to Figures 2 to 5 , in some embodiments, the air-cooling system 20 includes a compressor assembly 22, a four-way valve 23, a third heat exchanger 24, a power assembly 25, a solenoid valve 29, a first electronic expansion valve 26 and a second electronic expansion valve 27. The compressor assembly 22 is respectively connected to the third heat exchanger 24 and the first heat exchanger 21 through the four-way valve 23. The third heat exchanger 24 is connected to the power assembly 25 and the solenoid valve 29. The power assembly 25 and the solenoid valve 29 are arranged in parallel; the power assembly 25 and the solenoid valve 29 are connected to the heat exchange member 10 through the first electronic expansion valve 26, and the power assembly 25 and the solenoid valve 29 are connected to the first heat exchanger 21 through the second electronic expansion valve 27. The air-conditioning system 100 is configured to control at least one of the compressor assembly 22 and the power assembly 25 to provide heat or cold to the first heat exchanger 21 and the heat exchange member 10 according to the demand state of the load 1000 and the ambient temperature; the liquid-cooling system 30 includes a water pump 32. The outlet of the water pump 32 communicates with the inlet of the second heat exchanger 31 through the heat exchange member 10, and the outlet of the second heat exchanger 31 communicates with the inlet of the water pump 32.

[0065] In this way, by arranging the compressor assembly 22 and the power assembly 25 in the air-cooling system 20, the air-cooling system 20 can provide heat or cold to the first heat exchanger 21 and the heat exchange member 10, and the liquid-cooling system 30 is provided with a water pump 32. The water pump 32 can pump the cooling water to the heat exchange member 10 for heat exchange and then enter the second heat exchanger 31. Thus, the air-cooling system 20 and the liquid-cooling system 30 can cooperate to perform thermal management on the load 1000.

[0066] Specifically, the air-cooling system 20 includes a compressor assembly 22, a four-way valve 23, a third heat exchanger 24, a power assembly 25, a first electronic expansion valve 26, and a second electronic expansion valve 27. Among them, the compressor assembly 22 and the power assembly 25 can provide power to the air-conditioning system 100. For example, when the heating element needs to dissipate heat, the compressor assembly 22 and the power assembly 25 can push the refrigerant to continuously circulate in the air-conditioning system 100, so as to achieve a continuous heat dissipation effect.

[0067] The compressor assembly 22 and the power assembly 25 are in a parallel relationship in the air-cooling system 20, and the compressor assembly 22 and the power assembly 25 can be respectively connected to the heat exchange element 10, so that the compressor assembly 22 and the power assembly 25 can control the circulation of the refrigerant in the air-cooling system 20, so that the heat or cold generated by the compressor 221 is transferred to the heat exchange element 10 and the first heat exchanger 21 through the refrigerant.

[0068] The compressor assembly 22 can be respectively connected to the third heat exchanger 24 and the first heat exchanger 21 through the four-way valve 23, so that the high-temperature and high-pressure gaseous refrigerant compressed by the compressor assembly 22 can flow to the third heat exchanger 24 and the first heat exchanger 21 respectively according to the demand state and the four-way valve 23, and the third heat exchanger can be divided into an evaporator and a condenser according to the demand state of the load 1000. For example, in the heating demand state, the third heat exchanger 24 is an evaporator, and the high-temperature and high-pressure gaseous refrigerant compressed by the compressor assembly 22 can flow to the first heat exchanger 21 through the four-way valve 23; in the heat dissipation demand state, the third heat exchanger 24 is a condenser, and the high-temperature and high-pressure gaseous refrigerant compressed by the compressor assembly 22 can flow to the third heat exchanger 24 through the four-way valve 23.

[0069] The air-conditioning system 100 further includes a liquid storage tank 28 and a solenoid valve 29. The third heat exchanger 24 is connected to the liquid storage tank 28, and the high-temperature and high-pressure gaseous refrigerant can become a high-pressure and low-temperature liquid refrigerant after condensation in the third heat exchanger 24 and flow into the liquid storage tank 28. Thus, the liquid storage tank 28 can be connected to the first electronic expansion valve 26 and the second electronic expansion valve 27 through the solenoid valve 29, so that the refrigerant in the liquid storage tank 28 can flow through the solenoid valve 29 and the first electronic expansion valve 26 and then enter the heat exchange element 10, and flow through the second electronic expansion valve 27 and then flow into the first heat exchanger 21.

[0070] And the liquid storage tank 28 can be connected to the power assembly 25, and the power assembly 25 can be connected to the heat exchange element 10 through the first electronic expansion valve 26, so that the high-pressure and low-temperature liquid refrigerant can exchange heat with the liquid-cooling system 30 through the heat exchange element 10, and the power assembly 25 is connected to the first heat exchanger 21 through the second electronic expansion valve 27, and the high-pressure and low-temperature liquid refrigerant can exchange heat with the first heat exchanger 21.

[0071] According to the ambient temperature where the load 1000 is located and the demand state that appears in the load 1000, at least one of the compressor assembly 22 and the power assembly 25 can be selected to control the circulation of the refrigerant in the air-cooled system 20, so that the refrigerant can pass through the heat exchange member 10 and the first heat exchanger 21, and heat exchange is carried out on the liquid-cooled system 30 through the heat exchange member 10, and heat exchange is carried out on the storage device 600 through the first heat exchanger 21.

[0072] The liquid-cooled system 30 includes a water pump 32 and an expansion tank 33. The coolant in the expansion tank 33 can be supplied to the water pump 32, and the water pump 32 can provide power for the flow of the coolant. Among them, the outlet of the water pump 32 can be connected to the inlet of the second heat exchanger 31 through the heat exchange member 10, so that the coolant can exchange heat with the air-cooled system 20 when flowing through the heat exchange member 10, and the coolant after heat exchange can flow into the second heat exchanger 31 for heat exchange. By connecting the outlet of the second heat exchanger 31 to the inlet of the water pump 32 through the expansion tank 33, the coolant can circulate in the liquid-cooled system 30, so that the coolant can be reused.

[0073] Please refer to Figures 2 to 5 , in some embodiments, the power assembly 25 includes a first valve 251, a second valve 252 and a fluorine pump 253. The third heat exchanger 24 is connected to the fluorine pump 253 through the first valve 251. The fluorine pump 253 is connected to the heat exchange member 10 through the second valve 252 and the first electronic expansion valve 26. The fluorine pump 253 is connected to the first heat exchanger 21 through the second valve 252 and the second electronic expansion valve 27. The first valve 251 and the second valve 252 are configured to control the fluorine pump 253 to provide heat or cold to the first heat exchanger 21 and the heat exchange member 10.

[0074] In this way, by arranging the first valve 251 and the second valve 252 at both ends of the fluorine pump 253, the power assembly 25 can be controlled to provide heat or cold to the first heat exchanger 21 and the heat exchange member 10 according to different demand states of the load 1000.

[0075] Specifically, the power component 25 includes a first valve 251, a second valve 252, and a fluorine pump 253. Among them, the first valve 251 and the second valve 252 are arranged at both ends of the fluorine pump 253, so that the first valve 251 and the second valve 252 can control the opening and closing of the fluorine pump 253. The first valve 251 and the second valve 252 can be cube valves, and the first outlet of the liquid storage tank 28 in the air-cooling system 20 is arranged to be communicable with the first valve 251, so that the first valve 251 can control whether the refrigerant in the liquid storage tank 28 flows into the fluorine pump 253. The second valve 252 can be communicable with the first electronic expansion valve 26 and the second electronic expansion valve 27, so that the second valve 252 can control whether the refrigerant flowing out of the fluorine pump 253 flows to the first electronic expansion valve 26 and the second electronic expansion valve 27, and the second valve 252 can also prevent the refrigerant flowing out of the second outlet of the liquid storage tank 28 from flowing back into the fluorine pump 253.

[0076] In the case where the heating element is in a heat dissipation demand state and a low-temperature environment, the low-temperature environment takes away a part of the heat of the storage device 600, so that a large amount of refrigerant is not required to participate in heat dissipation. The compressor assembly 22 can be turned off, and the first valve 251 and the second valve 252 are controlled to be opened. After the fluorine pump 253 receives the liquid refrigerant flowing out of the liquid storage tank 28, the fluorine pump 253 can supply the refrigerant in the liquid storage tank 28 to the heat exchange element 10 and the first heat exchanger 21 for heat dissipation.

[0077] Please refer to Figures 2 to 5 , in some embodiments, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222, and a first one-way valve 223. The outlet of the compressor 221 is communicable with a four-way valve 23. The inlet of the gas-liquid separator 222 is communicable with the first heat exchanger 21 through the four-way valve 23. The outlet of the gas-liquid separator 222 is communicable with the four-way valve 23 through the first one-way valve 223. The outlet of the gas-liquid separator 222 is communicable with the inlet of the compressor 221.

[0078] In this way, by arranging the first one-way valve 223 between the gas-liquid separator 222 and the compressor 221, and the first one-way valve 223 can be communicable with the gas-liquid separator 222 and the four-way valve 23, the refrigerant can flow into the four-way valve 23 from the first one-way valve 223, which can reduce the operation of the compressor 221 and lower the energy consumption.

[0079] Specifically, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222, and a first check valve 223. Among them, the compressor 221 can compress the liquid refrigerant into a high-pressure and high-temperature gaseous refrigerant and provide the driving force for the refrigerant flow; the gas-liquid separator 222 can separate the gaseous refrigerant and the liquid refrigerant included in the refrigerant flowing into the compressor 221 to prevent the liquid refrigerant from entering the compressor 221 and causing liquid hammer in the compressor 221, resulting in damage to the compressor 221; the first check valve 223 can control the refrigerant to flow in one direction and prohibit the refrigerant from flowing in the reverse direction.

[0080] The outlet of the compressor 221 can be connected to the four-way valve 23, so that the refrigerant can flow from the four-way valve 23 to the third heat exchanger 24 or the first heat exchanger 21 after being compressed by the compressor 221. The inlet of the gas-liquid separator 222 is connected to the first heat exchanger 21 through the four-way valve 23, so that the refrigerant that has undergone heat exchange in the first heat exchanger 21 can flow back to the gas-liquid separator 222 through the four-way valve 23. The outlet of the gas-liquid separator 222 is connected to the four-way valve 23 through the first check valve 223, so that the refrigerant in the gas-liquid separator 222 can flow from the four-way valve 23 to the third heat exchanger 24 without being compressed by the compressor 221. The outlet of the gas-liquid separator 222 is connected to the inlet of the compressor 221, so that the refrigerant in the gas-liquid separator 222 can flow back into the compressor 221.

[0081] Please refer to Figures 6 to 8 In some embodiments, the air-cooling system 20 includes a compressor assembly 22, a third heat exchanger 24, a power assembly 25, a second check valve 224, a first electronic expansion valve 26, and a second electronic expansion valve 27. The compressor assembly 22 is respectively connected to the third heat exchanger 24 and the first heat exchanger 21. The third heat exchanger 24 is connected to the power assembly 25 and the second check valve 224. The power assembly 25 and the second check valve 224 are connected to the heat exchange member 10 through the first electronic expansion valve 26. The power assembly 25 and the second check valve 224 are connected to the first heat exchanger 21 through the second electronic expansion valve 27. The air-conditioning system 100 is configured to control at least one of the compressor assembly 22 and the power assembly 25 to provide heat or cold to the first heat exchanger 21 and the heat exchange member 10 according to the demand state of the load 1000 and the ambient temperature; the liquid-cooling system 30 includes a water pump 32. The outlet of the water pump 32 is connected to the inlet of the second heat exchanger 31 through the heat exchange member 10, and the outlet of the second heat exchanger 31 is connected to the inlet of the water pump 32.

[0082] In this way, by arranging the compressor assembly 22 and the power assembly 25 in the air-cooling system 20, the air-cooling system 20 can provide heat or cold to the first heat exchanger 21 and the heat exchange member 10. And the liquid-cooling system 30 is provided with a water pump 32, and the water pump 32 can provide the driving force for the cooling water, so that the cooling water flows through the heat exchange member 10 for heat exchange and then enters the second heat exchanger 31. Thus, the air-cooling system 20 and the liquid-cooling system 30 can cooperate to perform thermal management on the load 1000.

[0083] Specifically, the air-cooling system 20 includes a compressor assembly 22, a third heat exchanger 24, a power assembly 25, a first electronic expansion valve 26 and a second electronic expansion valve 27. Among them, the compressor assembly 22 and the power assembly 25 can provide power to the air-conditioning system 100. For example, when the load 1000 needs to dissipate heat, the compressor assembly 22 and the power assembly 25 can push the refrigerant to continuously circulate in the air-conditioning system 100, so as to achieve a continuous heat dissipation effect.

[0084] The compressor assembly 22 and the power assembly 25 are in a parallel relationship in the air-cooling system 20, and the compressor assembly 22 and the power assembly 25 can be respectively connected to the heat exchange member 10. Thus, the compressor assembly 22 and the power assembly 25 can control the circulation of the refrigerant in the air-cooling system 20, so that the heat or cold generated by the compressor 221 is transferred to the heat exchange member 10 and the first heat exchanger 21 through the refrigerant.

[0085] The compressor assembly 22 can be respectively connected to the third heat exchanger 24 and the first heat exchanger 21, so that the high-temperature and high-pressure gaseous refrigerant compressed by the compressor assembly 22 can flow to the third heat exchanger 24 and the first heat exchanger 21 respectively according to the required state. For example, in the heat dissipation demand state, the high-temperature and high-pressure gaseous refrigerant compressed by the compressor assembly 22 can flow to the third heat exchanger 24.

[0086] The air-conditioning system 100 further includes a liquid storage tank 28 and a second one-way valve 224. The third heat exchanger 24 is connected to the liquid storage tank 28, and the power assembly 25 and the second one-way valve 224 are arranged in parallel. The high-temperature and high-pressure gaseous refrigerant can become a high-pressure and low-temperature liquid refrigerant after condensation in the third heat exchanger 24 and flow into the liquid storage tank 28. Thus, the liquid storage tank 28 can be connected to the first electronic expansion valve 26 and the second electronic expansion valve 27 through the second one-way valve 224. Thus, the refrigerant in the liquid storage tank 28 can flow through the second one-way valve 224 and the first electronic expansion valve 26 and then enter the heat exchange member 10, and flow through the second electronic expansion valve 27 and then flow into the first heat exchanger 21.

[0087] Moreover, the liquid storage tank 28 can be connected to the power assembly 25, and the power assembly 25 can be connected to the heat exchanger 10 through the first electronic expansion valve 26, so that the high-pressure and low-temperature liquid refrigerant can exchange heat with the liquid cooling system 30 through the heat exchanger 10, and the power assembly 25 is connected to the first heat exchanger 21 through the second electronic expansion valve 27, and the high-pressure and low-temperature liquid refrigerant can exchange heat with the first heat exchanger 21.

[0088] According to the ambient temperature of the load 1000 and the required state of the load 1000, at least one of the compressor assembly 22 and the power assembly 25 can be selected to control the circulation of the refrigerant in the air-cooled system 20, so that the refrigerant can pass through the heat exchanger 10 and the first heat exchanger 21, and exchange heat with the liquid cooling system 30 through the heat exchanger 10, and exchange heat with the storage device 600 through the first heat exchanger 21.

[0089] The liquid cooling system 30 includes a water pump 32 and an expansion tank 33. The coolant in the expansion tank 33 can be supplied to the water pump 32, and the water pump 32 can provide the power for the coolant to flow. Among them, the outlet of the water pump 32 can be connected to the inlet of the second heat exchanger 31 through the heat exchanger 10, so that the coolant can exchange heat with the air-cooled system 20 when flowing through the heat exchanger 10, and the coolant after heat exchange can flow into the second heat exchanger 31 for heat exchange. By connecting the outlet of the second heat exchanger 31 to the inlet of the water pump 32 through the expansion tank 33, the coolant can circulate in the liquid cooling system 30, so that the coolant can be reused.

[0090] Please refer to Figures 6 to 8 , in some embodiments, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222 and a first check valve 223. The outlet of the compressor 221 is connected to the third heat exchanger 24, the inlet of the gas-liquid separator 222 is connected to the first heat exchanger 21, the outlet of the gas-liquid separator 222 is connected to the third heat exchanger 24 through the first check valve 223, the outlet of the gas-liquid separator 222 is connected to the inlet of the compressor 221, and the first check valve 223 is arranged in parallel with the compressor 221.

[0091] In this way, by arranging the first check valve 223 between the gas-liquid separator 222 and the compressor 221, and the first check valve 223 can connect the gas-liquid separator 222 and the third heat exchanger 24, so that the refrigerant can flow into the four-way valve 23 from the first check valve 223, the operation of the compressor 221 can be reduced and the energy consumption can be reduced.

[0092] Specifically, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222, and a first check valve 223. Among them, the compressor 221 can compress the liquid refrigerant into a high-pressure and high-temperature gaseous refrigerant and provide the driving force for the refrigerant flow; the gas-liquid separator 222 can separate the gaseous refrigerant and the liquid refrigerant included in the refrigerant flowing into the compressor 221 to prevent the liquid refrigerant from entering the compressor 221 and causing liquid hammer in the compressor 221, resulting in damage to the compressor 221; the first check valve 223 can control the refrigerant to flow in one direction and prohibit the refrigerant from flowing in the reverse direction.

[0093] The outlet of the compressor 221 can be connected to the third heat exchanger 24, so that the refrigerant can flow to the third heat exchanger 24 after being compressed by the compressor 221. The inlet of the gas-liquid separator 222 can be connected to the first heat exchanger 21, so that the refrigerant that has undergone heat exchange in the first heat exchanger 21 can flow back to the gas-liquid separator 222. The outlet of the gas-liquid separator 222 is connected to the third heat exchanger 24 through the first check valve 223, so that the refrigerant in the gas-liquid separator 222 can flow to the third heat exchanger 24 without being compressed by the compressor 221. The outlet of the gas-liquid separator 222 is connected to the inlet of the compressor 221, so that the refrigerant in the gas-liquid separator 222 can flow back to the compressor 221.

[0094] Please refer to Figure 9 , in some embodiments, the air-conditioning system 100 includes an indoor fan 40 and an electric heating element 50. The electric heating element 50 is arranged at the air outlet of the indoor fan 40. The air-conditioning system 100 is configured to: when the load 1000 is in a heating demand state, control the air-cooling system 20 and the liquid-cooling system 30 to be turned off, and control the electric heating element 50 and the indoor fan 40 to be started, so that the electric heating element 50 heats the air flow blown by the indoor fan 40 towards the load 1000.

[0095] In this way, when the load 1000 needs to be heated and the air-cooling system 20 and the liquid-cooling system 30 are unable to provide heat to the load 1000, by starting the electric heating element 50 and the indoor fan 40, when the indoor fan 40 blows air towards the load 1000, the electric heating element 50 can heat the air flow, and thus can provide heat to the load 1000.

[0096] Specifically, when the load 1000 is in a low-temperature outdoor environment and the air-cooling system 20 and the liquid-cooling system 30 only have the function of dissipating heat from the load 1000, by arranging an electric heating element 50 in the indoor fan 40 included in the air-conditioning system 100, the air flow blown by the indoor fan 40 towards the load 1000 can be heated by the electric heating element 50, so as to meet the heating requirement of the load 1000. Among them, the electric heating element 50 can be a PTC heater, and the PTC heater can be arranged at the air outlet of the indoor fan 40 or in the air duct of the indoor fan 40, so that the indoor fan 40 can blow hot air towards the load 1000 and provide heat to the load 1000.

[0097] In some embodiments, when the indoor temperature of the load 1000 is less than the first preset temperature, it is determined that the demand state of the load 1000 is a heating demand state; when the indoor temperature of the load 1000 is less than or equal to the second preset temperature and greater than or equal to the first preset temperature, it is determined that the demand state of the load 1000 is a standby state; when the indoor temperature of the load 1000 is greater than the second preset temperature, it is determined that the demand state of the load 1000 is a heat dissipation demand state; the first preset temperature is less than the second preset temperature.

[0098] In this way, by comparing the indoor temperature of the load 1000 with the preset temperature, the demand state of the load 1000 can be accurately understood, so as to dissipate heat and heat the load 1000 in a timely manner.

[0099] Specifically, the air-conditioning system 100 needs to determine whether the air-conditioning system 100 starts and the demand state of the load 1000 according to the ambient temperature of the load 1000, and the start mode of the air-conditioning system 100 can be determined according to the demand state. Among them, a first preset temperature and a second preset temperature are set in the air-conditioning system 100, and the air-conditioning system 100 can collect the indoor temperature of the load 1000 in real time. By comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, the start of the air-conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison results.

[0100] For example, when the indoor temperature of the load 1000 is less than the first preset temperature, it is determined that the demand state of the load 1000 is a heating demand state, and the air-conditioning system 100 starts the heating mode according to the heating demand state; when the indoor temperature of the load 1000 is less than or equal to the second preset temperature and greater than or equal to the first preset temperature, it is determined that the demand state of the load 1000 is a standby state, which means that the load 1000 does not need heating or heat dissipation at this time; when the indoor temperature of the load 1000 is greater than the second preset temperature, it is determined that the demand state of the load 1000 is a heat dissipation demand state, and the air-conditioning system 100 starts the heat dissipation mode according to the heat dissipation demand state.

[0101] It should be noted that the first preset temperature is less than the second preset temperature. For example, the first preset temperature can be 20 degrees Celsius, and the second preset temperature can be 25 degrees Celsius.

[0102] Please refer to Figures 2 to 5 , in some embodiments, the air-cooling system 20 includes a compressor assembly 22, a power assembly 25, and a first heat exchanger 21, the liquid-cooling system 30 includes a second heat exchanger 31, and the air-conditioning system 100 is configured to: when the load 1000 is in a heat dissipation demand state and the first outdoor ambient temperature, control the compressor assembly 22 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31; when the load 1000 is in a heat dissipation demand state and the second outdoor ambient temperature, control the compressor assembly 22 and the power assembly 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31; when the load 1000 is in a heat dissipation demand state and the third outdoor ambient temperature, control the power assembly 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31; the magnitudes of the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature decrease in sequence.

[0103] In this way, by controlling at least one of the compressor assembly 22 and the power assembly 25 to provide cooling capacity to the heat exchange member 10 and the second heat exchanger 31 according to the outdoor temperature, different components can be selected to provide cooling capacity according to different temperature conditions, which can ensure the heat dissipation efficiency while saving energy consumption.

[0104] Specifically, the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature are set in the air-conditioning system 100. The air-conditioning system 100 collects the outdoor ambient temperature in real time, compares the outdoor ambient temperature with the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature respectively, and can control at least one of the compressor assembly 22 and the power assembly 25 to provide cooling capacity to the heat exchange member 10 and the second heat exchanger 31 according to the comparison result. Among them, the magnitudes of the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature decrease in sequence. It should be noted that the first outdoor ambient temperature can be from 5 degrees Celsius to 15 degrees Celsius, the second outdoor ambient temperature can be from -5 degrees Celsius to 5 degrees Celsius, and the third outdoor ambient temperature can be below -5 degrees Celsius.

[0105] For example, according to Figure 2As shown, when the load 1000 is in a heat dissipation demand state and the first outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is relatively high, and natural heat dissipation cannot meet the heat dissipation demand of the load 1000. Therefore, the air conditioning system 100 can control the compressor assembly 22 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31. In the air cooling system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the third heat exchanger 24 through the four-way valve 23. Then, after the refrigerant condenses in the third heat exchanger 24, it flows into the heat exchange member 10 and the first heat exchanger 21 respectively for heat exchange. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 to be compressed again; in the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 to be pumped again.

[0106] For another example, according to Figure 3 As shown, when the load 1000 is in a heat dissipation demand state and the second outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is relatively low, and the efficiency of natural heat dissipation for the load 1000 is slow. Therefore, the air conditioning system 100 can control the compressor assembly 22 and the power assembly 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31. In the air cooling system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the third heat exchanger 24 through the four-way valve 23. Then, after the refrigerant condenses in the third heat exchanger 24, the refrigerant is respectively flowed into the heat exchange member 10 and the first heat exchanger 21 for heat exchange through the fluorine pump 253. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 to be compressed again; in the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 to be pumped again.

[0107] For yet another example, according to Figure 4As shown, when the load 1000 is in a heat dissipation demand state and the third outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is low. Natural heat dissipation can meet part of the heat dissipation of the load 1000. Thus, the air-conditioning system 100 can control the power component 25 to supply cold energy to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 supplies cold energy to the second heat exchanger 31. In the air-cooling system 20, first, the fluorine pump 253 can make the refrigerant existing in the pipeline flow into the heat exchange member 10 and the first heat exchanger 21 respectively for heat exchange. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation. Finally, the refrigerant after liquid separation can flow through the first one-way valve 223 and the four-way valve 23 from the gas-liquid separator 222 and enter the third heat exchanger 24, and no longer enter the compressor 221; in the liquid-cooling system 30, first, the coolant can be pumped by the water pump 32 and flow into the heat exchange member 10 for heat exchange, then flow into the second heat exchanger 31 for heat exchange, and finally, the coolant after heat exchange can flow back to the water pump 32 from the second heat exchanger 31 to be pumped again.

[0108] Please refer to Figure 5 , in some embodiments, the air-cooling system 20 includes a compressor assembly 22, a power component 25, and a first heat exchanger 21, the liquid-cooling system 30 includes a second heat exchanger 31, and the air-conditioning system 100 is configured to: when the load 1000 is in a heating demand state, control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 supplies heat to the second heat exchanger 31.

[0109] In this way, according to the indoor temperature of the load 1000, the compressor assembly 22 is controlled to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the load 1000 can be heated when the indoor temperature is low, and the operating efficiency of the load 1000 can be improved.

[0110] Specifically, a first preset temperature and a second preset temperature are set in the air-conditioning system 100, and the air-conditioning system 100 can collect the indoor temperature of the load 1000 in real time. By comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, the start of the air-conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison results.

[0111] For example, according to Figure 5As shown, when the load 1000 is in a heating demand state, the air conditioning system 100 can control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides heat to the second heat exchanger 31. In the air-cooled system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the first heat exchanger 21 and the heat exchange member 10 through the four-way valve 23 for heat exchange. Then, the refrigerant after heat exchange can flow into the third heat exchanger 24 from the first heat exchanger 21 and the heat exchange member 10 for condensation. Finally, the condensed refrigerant can enter the gas-liquid separator 222 from the third heat exchanger 24 through the four-way valve 23 for liquid separation. The refrigerant after liquid separation can enter the compressor 221 to be compressed again; in the liquid-cooled system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back to the water pump 32 from the second heat exchanger 31 to be pumped again.

[0112] Please refer to Figure 1 、 Figure 10 and Figure 11 A control method for an air conditioning system 100 provided by an embodiment of the present invention. The air conditioning system includes a heat exchange member 10, a liquid-cooled system 30 and an air-cooled system 20. The liquid-cooled system 30 and the air-cooled system 20 are connected through the heat exchange member 10. One of the liquid-cooled system 30 and the air-cooled system 20 provides heat or cold to the other through the heat exchange member 10. The control method includes:

[0113] Step 011: Obtain the demand state of the load 1000 and the ambient temperature;

[0114] Step 012: Control the liquid-cooled system 30 and the air-cooled system 20 to perform thermal management on the load 1000 according to the demand state of the load 1000 and the ambient temperature.

[0115] In this way, the heat exchange member 10 is used to connect the liquid-cooled system 30 and the air-cooled system 20, so that the liquid-cooled system 30 and the air-cooled system 20 can share a set of refrigeration and heating devices, thereby saving costs compared to the independent configuration and deployment of the liquid-cooled system 30 and the air-cooled system 20. Moreover, the air-cooled system 20 and the liquid-cooled system 30 can perform thermal management on the air conditioner at the same time, improving the overall heat dissipation efficiency of the air conditioner.

[0116] Among them, the air-conditioning system includes a heat exchanger 10, a liquid cooling system 30 and an air cooling system 20. Among them, the liquid cooling system 30 can utilize the high thermal conductivity and high heat capacity characteristics of the liquid, and absorb and transfer heat through the circulating coolant to realize the heat dissipation of the heating device. The air cooling system 20 can realize the reduction of the temperature of the storage device through the circulating flow and phase change of the refrigerant. The liquid cooling system 30 and the air cooling system 20 can be connected through the heat exchanger 10, so that one of the liquid cooling system 30 and the air cooling system 20 provides heat or cold to the other through the heat exchanger 10. A control device 300 for controlling the air-conditioning system 100 is provided on the housing system. The control device 300 includes a processor 310, a memory 320 and a computer program 321. Among them, the computer program 321 is stored in the memory 320 and is executed by the processor 310. The computer program 321 includes instructions for executing the control method of the air-conditioning system 100.

[0117] Specifically, the processor 310 can obtain the ambient temperature in which the load 1000 is located. For example, by setting temperature sensors inside and outside the load 1000, the temperature sensors can obtain the indoor ambient temperature and the outdoor ambient temperature and transmit the ambient temperature to the processor 310. The processor 310 can determine the demand state of the load 1000 according to the obtained indoor ambient temperature, and it should be noted that the demand state of the load 1000 includes a heating demand state and a heat dissipation demand state.

[0118] For example, a first preset temperature and a second preset temperature are set in the memory 320, and the processor 310 can collect the indoor temperature of the load 1000 in real time. By comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, according to the comparison results, the processor 310 can control the startup of the air-conditioning system 100 and the demand state of the load 1000. Thus, when the indoor temperature of the load 1000 is less than the first preset temperature, the processor 310 can determine that the demand state of the load 1000 is the heating demand state, and the air-conditioning system 100 starts the heating mode according to the heating demand state; when the indoor temperature of the load 1000 is less than or equal to the second preset temperature and greater than or equal to the first preset temperature, the processor 310 can determine that the demand state of the load 1000 is the standby state, which means that the load 1000 does not need heating or heat dissipation at this time; when the indoor temperature of the load 1000 is greater than the second preset temperature, the processor 310 determines that the demand state of the load 1000 is the heat dissipation demand state, and the air-conditioning system 100 starts the heat dissipation mode according to the heat dissipation demand state.

[0119] It should be noted that the first preset temperature is less than the second preset temperature. For example, the first preset temperature can be 25 degrees Celsius, and the second preset temperature can be 20 degrees Celsius.

[0120] According to the acquired demand status and ambient temperature of the load 1000, the processor 310 can control the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000.

[0121] Please refer to Figure 12 , in some embodiments, the air cooling system 20 includes a compressor assembly 22, a power assembly 25, and a first heat exchanger 21, the liquid cooling system 30 includes a second heat exchanger 31, step 012: According to the demand status and ambient temperature of the load 1000, controlling the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000 includes:

[0122] Step 0121: When the load 1000 is in a heat dissipation demand state and the first outdoor ambient temperature, control the compressor assembly 22 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31;

[0123] Step 0122: When the load 1000 is in a heat dissipation demand state and the second outdoor ambient temperature, control the compressor assembly 22 and the power assembly 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31;

[0124] Step 0123: When the load 1000 is in a heat dissipation demand state and the third outdoor ambient temperature, control the power assembly 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31.

[0125] In this way, at least one of the compressor assembly 22 and the power assembly 25 is controlled to provide cooling capacity to the heat exchange member 10 and the second heat exchanger 31 according to the outdoor temperature of the load 1000, so that different components can be selected to provide cooling capacity according to different temperature conditions, which can ensure the heat dissipation efficiency while saving energy consumption.

[0126] Specifically, the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature are set in the memory 320. The processor 310 can collect the outdoor ambient temperature in real time, and compare the outdoor ambient temperature with the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature respectively. According to the comparison results, at least one of the compressor assembly 22 and the power assembly 25 can be controlled to provide cooling capacity to the heat exchange member 10 and the second heat exchanger 31. Among them, the magnitudes of the first outdoor ambient temperature, the second outdoor ambient temperature, and the third outdoor ambient temperature decrease in sequence. It should be noted that the first outdoor ambient temperature can be 5 degrees Celsius to 15 degrees Celsius, the second outdoor ambient temperature can be -5 degrees Celsius to 5 degrees Celsius, and the third outdoor ambient temperature can be below -5 degrees Celsius.

[0127] For example, when the load 1000 is in a heat dissipation demand state and the first outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is relatively high, and natural heat dissipation cannot meet the heat dissipation demand of the load 1000. Thus, the processor 310 can control the compressor assembly 22 to supply cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 supplies cooling capacity to the second heat exchanger 31. In the air-cooled system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the third heat exchanger 24 through the four-way valve 23. Next, after the refrigerant condenses in the third heat exchanger 24, it flows into the heat exchange member 10 and the first heat exchanger 21 respectively for heat exchange. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 to be compressed again; in the liquid-cooled system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 to be pumped again.

[0128] For another example, when the load 1000 is in a heat dissipation demand state and the second outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is relatively low, and the efficiency of natural heat dissipation for the load 1000 is slow. Thus, the processor 310 can control the compressor assembly 22 and the power assembly 25 to supply cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 supplies cooling capacity to the second heat exchanger 31. In the air-cooled system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the third heat exchanger 24 through the four-way valve 23. Next, after the refrigerant condenses in the third heat exchanger 24, the refrigerant is respectively flowed into the heat exchange member 10 and the first heat exchanger 21 for heat exchange through the fluorine pump 253. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 to be compressed again; in the liquid-cooled system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 to be pumped again.

[0129] For another example, when the load 1000 is in a heat dissipation demand state and the third outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is low. Natural heat dissipation can meet part of the heat dissipation of the load 1000. Thus, the processor 310 can control the power component 25 to provide cooling capacity to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides cooling capacity to the second heat exchanger 31. In the air cooling system 20, first, the fluorine pump 253 can make the refrigerant existing in the pipeline flow into the heat exchange member 10 and the first heat exchanger 21 respectively for heat exchange. Then, the refrigerant after heat exchange flows through the four-way valve 23 from the first heat exchanger 21 and the heat exchange member 10 and enters the gas-liquid separator 222 for liquid separation. Finally, the separated refrigerant can flow through the first one-way valve 223 and the four-way valve 23 from the gas-liquid separator 222 and enter the third heat exchanger 24, and no longer enter the compressor 221. In the liquid cooling system 30, first, the coolant can flow into the heat exchange member 10 through the pump pressure of the water pump 32 for heat exchange, then flow into the second heat exchanger 31 for heat exchange, and finally, the coolant after heat exchange can flow back to the water pump 32 from the second heat exchanger 31 to be pumped again.

[0130] Please refer to Figure 13 , in some embodiments, the air cooling system 20 includes a compressor assembly 22, a power component 25, and a first heat exchanger 21, and the liquid cooling system 30 includes a second heat exchanger 31. Step 012: According to the demand state of the load 1000 and the ambient temperature, control the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000, including:

[0131] Step 0124: When the load 1000 is in a heating demand state, control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 provides heat to the second heat exchanger 31.

[0132] In this way, according to the indoor temperature of the load 1000, control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the load 1000 can be heated when the indoor temperature is low, and the operating efficiency of the load 1000 can be improved.

[0133] Specifically, a first preset temperature and a second preset temperature are set in the memory 320, and the processor 310 can collect the indoor temperature of the load 1000 in real time. By comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, the start of the air conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison results.

[0134] For example, when the load 1000 is in a heating demand state, the processor 310 can control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange member 10, so that the heat exchange member 10 supplies heat to the second heat exchanger 31. In the air-cooled system 20, first, the refrigerant can be compressed by the compressor 221 and then flow into the first heat exchanger 21 and the heat exchange member 10 through the four-way valve 23 for heat exchange. Then, the refrigerant after heat exchange can flow into the third heat exchanger 24 from the first heat exchanger 21 and the heat exchange member 10 for condensation. Finally, the refrigerant after condensation can enter the gas-liquid separator 222 from the third heat exchanger 24 through the four-way valve 23 for liquid separation. The refrigerant after liquid separation can enter the compressor 221 to be compressed again; in the liquid-cooled system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange member 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant after heat exchange can flow back to the water pump 32 from the second heat exchanger 31 to be pumped again.
