[0002] At present, as the scale of data centers is getting larger and larger, the heat generated by data centers is also increasing. In the related art, data centers are equipped with inter-row air conditioners for heat dissipation. Inter-row air conditioners are usually equipped with two heat dissipation systems, a liquid cooling system and an air cooling system, according to the needs. The two heat dissipation systems each bear part of the heat dissipation needs in the data center. For example, liquid cooling can be used to cool components such as servers, and air cooling can be used to cool components such as hard disks.

[0044] See also Figures 1 to 5 An air conditioning system 100 provided in an embodiment of the present invention includes a heat exchanger 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 exchanger 10. 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. 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.

[0045] In this way, the liquid cooling system 30 and the air cooling system 20 are connected using the heat exchanger 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 to 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, thereby improving the overall heat dissipation efficiency of the air conditioner.

[0046] Among them, according to Figure 1 As shown, the load 1000 includes but is not limited to the components of the data center, and the components of the data center include but are not limited to the server 500 and the storage device 600. The data center is a building where electronic information equipment is centrally placed and provides its operating environment, and 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 server 500 and the storage device 600 need to release heat when working, the indoor temperature of the load 1000 increases, and the excessively high indoor temperature is likely to cause the load 1000 to have thermal runaway and other faults, so an air conditioning system 100 is provided in the load 1000 to dissipate heat for the server 500 and the storage device 600.

[0047] Specifically, the air conditioning system 100 includes a heat exchange component 10, a liquid cooling system 30, and an air cooling system 20. The liquid cooling system 30 can utilize the high thermal conductivity and high heat capacity characteristics of liquid to absorb and transfer heat through circulating coolant to achieve heat dissipation of the heat generating device. For example, the liquid cooling system 30 can indirectly dissipate heat with the server 500 through a heat transfer medium such as a liquid cooling plate. By circulating the coolant in the liquid cooling plate, the heat of the server 500 can be transferred to the coolant through the liquid cooling plate, thereby achieving the purpose of reducing the temperature of the server 500.

[0048] The air cooling system 20 is a heat dissipation system that uses air as a cooling medium to reduce the temperature of the heating device through gas convection. The air cooling system 20 can reduce the temperature of the heating component through the circulation and phase change of the refrigerant. For example. The air cooling system 20 can release the heat of 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 gas, so that the air temperature around the storage device 600 is reduced, and the cold air is blown to the storage device 600 by the fan to achieve the purpose of reducing the temperature of the energy storage device.

[0049] The liquid cooling system 30 and the air cooling system 20 can be connected via a heat exchanger 10. 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, which is formed by stacking metal sheets with a certain corrugated shape, and 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.

[0050] 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 the liquid cooling system 30 is provided with a component capable of heating and cooling, the liquid cooling system 30 can provide heat or cold to the air cooling system 20 through the heat exchanger 10; or when the liquid cooling system 30 is provided with a component capable of heating and cooling, the air cooling system 20 can provide heat or cold to the liquid cooling system 30 through the heat exchanger 10. This application is described by taking the air cooling system 20 providing heat or cold to the liquid cooling system 30 through the heat exchanger 10 as an example.

[0051] According to the demand state and ambient temperature of the load 1000, 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 is started 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 under the heat dissipation demand state.

[0052] See also Figures 2 to 5 In some embodiments, the air cooling system 20 includes a first heat exchanger 21, and 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 exchange element 10. The liquid cooling system 30 obtains heat or cold from the air cooling system 20 through the heat exchange element 10, and uses the heat or cold from the air cooling system 20 to heat or cool the second heat exchanger 31.

[0053] In this way, by configuring the air cooling system 20 to cool and heat the first heat exchanger 21 and the heat exchange element 10, the air cooling system 20 can provide heat or cold to the liquid cooling system 30, and the liquid cooling system 30 does not need to be configured with additional refrigeration components 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, thereby improving the overall heat dissipation efficiency of the air conditioner.

[0054] 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 can be cold plates. The first heat exchanger 21 is arranged on one side of the storage device 600, and can perform heat exchange on the storage device 600; the second heat exchanger 31 is arranged 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 element 10, so that the first heat exchanger 21 can heat or dissipate heat for 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 element 10, and use the heat or cold of the air cooling system 20 to transfer to the second heat exchanger 31, so that the second heat exchanger 31 can heat or dissipate heat for the server 500.

[0055] See also Figures 2 to 5In 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 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, and 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 first electronic expansion valve 26. The heat element 10, the power component 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 component 22 and the power component 25 to provide heat or cold to the first heat exchanger 21 and the heat exchange element 10 according to the demand state of the load 1000 and the ambient temperature; the liquid cooling system 30 includes a water pump 32, and the outlet of the water pump 32 is connected to the inlet of the second heat exchanger 31 through the heat exchange element 10, and the outlet of the second heat exchanger 31 is connected to the inlet of the water pump 32.

[0056] In this way, by setting a compressor assembly 22 and a 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 element 10, and the liquid cooling system 30 is provided with a water pump 32, which can pump cooling water 32 to the heat exchange element 10 for heat exchange and then enter the second heat exchanger 31, so that the air cooling system 20 and the liquid cooling system 30 can cooperate to perform thermal management on the load 1000.

[0057] 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. The compressor assembly 22 and the power assembly 25 can provide power to the air conditioning system 100. For example, when the heat generating element needs to dissipate heat, the compressor assembly 22 and the power assembly 25 can drive the refrigerant to circulate continuously in the air conditioning system 100, thereby achieving a continuous heat dissipation effect.

[0058] 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 connected to the heat exchange element 10 respectively, so that the compressor assembly 22 and the power assembly 25 can control the circulation flow 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.

[0059] The compressor assembly 22 can be connected to the third heat exchanger 24 and the first heat exchanger 21 respectively 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.

[0060] The air-conditioning system 100 also includes a liquid storage tank 28 and a solenoid valve 29. The third heat exchanger 24 is connected to the liquid storage tank 28. The high-temperature and high-pressure gaseous refrigerant can be converted into a high-pressure and low-temperature liquid refrigerant after being condensed by the third heat exchanger 24 and flow into the liquid storage tank 28. 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 then flow through the second electronic expansion valve 27 and then flow into the first heat exchanger 21.

[0061] In addition, the liquid storage tank 28 can be connected to the power component 25, and the power component 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 component 25 can be 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.

[0062] According to the ambient temperature of the load 1000 and the demand state of the load 1000, at least one of the compressor component 22 and the power component 25 can be selected to control the circulation of the refrigerant in the air cooling system 20, so that the refrigerant can pass through the heat exchange element 10 and the first heat exchanger 21, perform heat exchange on the liquid cooling system 30 through the heat exchange element 10, and perform heat exchange on the storage device 600 through the first heat exchanger 21.

[0063] 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 coolant with a flow force. 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 cooling system 20 when flowing through the heat exchanger 10, and the coolant after the 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.

[0064] See also 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 exchanger 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 exchanger 10.

[0065] Thus, by providing 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 element 10 according to different demand states of the load 1000 .

[0066] Specifically, the power assembly 25 includes a first valve 251, a second valve 252 and a fluorine pump 253. 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 square valves, and the first outlet of the liquid storage tank 28 arranged in the air cooling system 20 can be connected to 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 connected to 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 to the fluorine pump 253.

[0067] When the heat generating component is in a state where heat dissipation is required and in a low-temperature environment, the low-temperature environment takes away a portion of the heat of the storage device 600, so that a large amount of refrigerant is not required to participate in the heat dissipation. The compressor assembly 22 can be closed, and the first valve 251 and the second valve 252 can be controlled to open. 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 component 10 and the first heat exchanger 21 for heat dissipation.

[0068] See also 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.

[0070] Specifically, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222 and a first one-way valve 223. The compressor 221 can compress the liquid refrigerant into a high-pressure and high-temperature gaseous refrigerant and provide the power for the refrigerant to 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, thereby damaging the compressor 221; the first one-way valve 223 can control the refrigerant to flow in one direction and prohibit the refrigerant from flowing in the opposite direction.

[0071] 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 after 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 to the compressor 221.

[0072] See also Figures 6 to 8In some embodiments, the air cooling system 20 includes a compressor assembly 22, a third heat exchanger 24, a power assembly 25, a second one-way 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 one-way valve 224, the power assembly 25 and the second one-way valve 224 are connected to the heat exchanger 10 through the first electronic expansion valve 26, and the power assembly 25 and the second one-way 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 exchanger 10 according to the demand state and ambient temperature of the load 1000; 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 exchanger 10, and the outlet of the second heat exchanger 31 is connected to the inlet of the water pump 32.

[0073] In this way, by setting a compressor assembly 22 and a 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 element 10, and the liquid cooling system 30 is provided with a water pump 32, which can provide flowing power to the cooling water, so that the cooling water flows through the heat exchange element 10 for heat exchange and then enters the second heat exchanger 31, so that the air cooling system 20 and the liquid cooling system 30 can cooperate to perform thermal management on the load 1000.

[0074] 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. 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 drive the refrigerant to circulate continuously in the air conditioning system 100, thereby achieving a continuous heat dissipation effect.

[0075] 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 connected to the heat exchange element 10 respectively, so that the compressor assembly 22 and the power assembly 25 can control the circulation flow 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.

[0076] The compressor assembly 22 can be connected to the third heat exchanger 24 and the first heat exchanger 21, respectively, 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 according to the demand 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.

[0077] 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. After being condensed by the third heat exchanger 24, the high-temperature and high-pressure gaseous refrigerant can be converted into a high-pressure and low-temperature liquid refrigerant and flow into the liquid storage tank 28, so that 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, so that 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 exchanger 10, and then flow through the second electronic expansion valve 27 and then flow into the first heat exchanger 21.

[0078] In addition, the liquid storage tank 28 can be connected to the power component 25, and the power component 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 component 25 can be 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.

[0079] According to the ambient temperature of the load 1000 and the demand state of the load 1000, at least one of the compressor component 22 and the power component 25 can be selected to control the circulation of the refrigerant in the air cooling system 20, so that the refrigerant can pass through the heat exchange element 10 and the first heat exchanger 21, perform heat exchange on the liquid cooling system 30 through the heat exchange element 10, and perform heat exchange on the storage device 600 through the first heat exchanger 21.

[0080] 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 coolant with a flow force. 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 cooling system 20 when flowing through the heat exchanger 10, and the coolant after the 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.

[0081] See also Figures 6 to 8 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 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 one-way valve 223, the outlet of the gas-liquid separator 222 is connected to the inlet of the compressor 221, and the first one-way valve 223 is arranged in parallel with the compressor 221.

[0082] In this way, by setting the first one-way valve 223 between the gas-liquid separator 222 and the compressor 221, and the first one-way valve 223 can connect the gas-liquid separator 222 and the third heat exchanger 24, so that the refrigerant can flow from the first one-way valve 223 into the four-way valve 23, which can reduce the work of the compressor 221 and reduce energy consumption.

[0083] Specifically, the compressor assembly 22 includes a compressor 221, a gas-liquid separator 222 and a first one-way valve 223. The compressor 221 can compress the liquid refrigerant into a high-pressure and high-temperature gaseous refrigerant and provide the power for the refrigerant to 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, thereby damaging the compressor 221; the first one-way valve 223 can control the refrigerant to flow in one direction and prohibit the refrigerant from flowing in the opposite direction.

[0084] 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 after 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.

[0085] See also Fig. 9 In some embodiments, the air conditioning system 100 includes an indoor fan 40 and an electric heating element 50, and the electric heating element 50 is arranged at the air outlet of the indoor fan 40. The air conditioning system 100 is configured as follows: when the load 1000 is in a heating demand state, the air cooling system 20 and the liquid cooling system 30 are controlled to be turned off, and the electric heating element 50 and the indoor fan 40 are controlled to be started, so that the electric heating element 50 heats the airflow blown by the indoor fan 40 to the load 1000.

[0086] 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 to the load 1000, the electric heating element 50 can heat the airflow and thus provide heat to the load 1000.

[0087] 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 for the load 1000, an electric heating element 50 is provided in the indoor fan 40 included in the air conditioning system 100, so that the airflow blown by the indoor fan 40 to the load 1000 can be heated by the electric heating element 50, thereby meeting the heating demand of the load 1000. The electric heating element 50 may be a PTC heater, which may be provided 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 to the load 1000 and provide heat to the load 1000.

[0088] In certain embodiments, when the indoor temperature of load 1000 is less than the first preset temperature, the demand state of load 1000 is determined to be a heating demand state; when the indoor temperature of load 1000 is less than or equal to the second preset temperature and greater than or equal to the first preset temperature, the demand state of load 1000 is determined to be a standby state; when the indoor temperature of load 1000 is greater than the second preset temperature, the demand state of load 1000 is determined to be a cooling demand state; the first preset temperature is lower than the second preset temperature.

[0089] 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 that the load 1000 can be cooled and heated in time.

[0090] Specifically, the air conditioning system 100 needs to determine whether the air conditioning system 100 is started and the demand state of the load 1000 according to the ambient temperature of the load 1000, and the start-up mode of the air conditioning system 100 can be determined according to the demand state. Among them, the air conditioning system 100 is set with a first preset temperature and a second preset temperature, and the air conditioning system 100 can collect the indoor temperature of the load 1000 in real time, and by comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, the start-up of the air conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison result.

[0091] For example, when the indoor temperature of the load 1000 is lower than the first preset temperature, the demand state of the load 1000 is determined to be 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 lower than or equal to the second preset temperature and higher than or equal to the first preset temperature, the demand state of the load 1000 is determined to be a standby state, which means that the load 1000 does not need heating or heat dissipation; when the indoor temperature of the load 1000 is higher than the second preset temperature, the demand state of the load 1000 is determined to be a heat dissipation demand state, and the air-conditioning system 100 starts the heat dissipation mode according to the heat dissipation demand state.

[0092] It should be noted that the first preset temperature is lower than the second preset temperature. For example, the first preset temperature may be 20 degrees Celsius, and the second preset temperature may be 25 degrees Celsius.

[0093] See also 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 as follows: when the load 1000 is in a heat dissipation demand state and a first outdoor ambient temperature, the compressor assembly 22 is controlled to provide cooling to the first heat exchanger 21 and the heat exchanger 10, so that the heat exchanger 10 provides cooling to the second heat exchanger 31; when the load 1000 is in a heat dissipation demand state and a second outdoor ambient temperature, the compressor assembly 22 and the power assembly 25 are controlled to provide cooling to the first heat exchanger 21 and the heat exchanger 10, so that the heat exchanger 10 provides cooling to the second heat exchanger 31; when the load 1000 is in a heat dissipation demand state and a third outdoor ambient temperature, the power assembly 25 is controlled to provide cooling to the first heat exchanger 21 and the heat exchanger 10, so that the heat exchanger 10 provides cooling to the second heat exchanger 31; the first outdoor ambient temperature, the second outdoor ambient temperature and the third outdoor ambient temperature decrease in magnitude in sequence.

[0094] In this way, at least one of the compressor assembly 22 and the power assembly 25 is controlled by the outdoor temperature to provide cooling to the heat exchanger 10 and the second heat exchanger 31, so that different components can be selected to provide cooling according to different temperature conditions, which can ensure heat dissipation efficiency while saving energy.

[0095] 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, and compares 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 result, at least one of the compressor assembly 22 and the power assembly 25 can be controlled to provide cooling to the heat exchanger 10 and the second heat exchanger 31. Among them, the first outdoor ambient temperature, the second outdoor ambient temperature and the third outdoor ambient temperature decrease in magnitude. 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.

[0096] For example, according to Figure 2As shown, when the load 1000 is in a state of heat dissipation demand 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, so that the air-conditioning system 100 can control the compressor assembly 22 to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling 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, the refrigerant is condensed by the third heat exchanger 24 and then flows into the heat exchange element 10 and the first heat exchanger 21 for heat exchange. Then, the refrigerant that has undergone heat exchange flows from the first heat exchanger 21 and the heat exchange element 10 through the four-way valve 23 and then enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 for re-compression. In the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange element 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant that has undergone heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0097] For example, according to Figure 3 As shown, when the load 1000 is in a state of heat dissipation demand and the second outdoor ambient temperature, it indicates that the indoor temperature is too high and the outdoor temperature is low, and the efficiency of natural heat dissipation for the load 1000 is slow, so that the air-conditioning system 100 can control the compressor assembly 22 and the power assembly 25 to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling 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, the refrigerant is condensed by the third heat exchanger 24 and then flows into the heat exchanger 10 and the first heat exchanger 21 respectively through the fluorine pump 253 for heat exchange. Then, the refrigerant that has undergone heat exchange flows from the first heat exchanger 21 and the heat exchanger 10 through the four-way valve 23 and then enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 for re-compression. In the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchanger 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant that has undergone heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0098] For example, according to Figure 4As shown, when the load 1000 is in a state of heat dissipation demand and the third outdoor ambient temperature is, it indicates that the indoor temperature is too high and the outdoor temperature is low, and natural heat dissipation can meet part of the heat dissipation of the load 1000, so that the air-conditioning system 100 can control the power component 25 to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling to the second heat exchanger 31. In the air cooling system 20, first, the fluorine pump 253 can flow the refrigerant in the pipeline into the heat exchanger 10 and the first heat exchanger 21 for heat exchange, and then the refrigerant after heat exchange flows from the first heat exchanger 21 and the heat exchanger 10 through the four-way valve 23 and enters the gas-liquid separator 222 for liquid separation. Finally, the refrigerant after liquid separation can flow from the gas-liquid separator 222 through the first one-way valve 223 and the four-way valve 23 and enter the third heat exchanger 24, and no longer enters the compressor 221; in the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchanger 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange, and finally the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0099] See also Figure 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 heating demand state, control the compressor assembly 22 to supply heat to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides heat to the second heat exchanger 31.

[0100] In this way, the compressor assembly 22 is controlled to supply heat to the first heat exchanger 21 and the heat exchange element 10 according to the indoor temperature of the load 1000 , so that the load 1000 can be heated when the indoor temperature is low, thereby improving the operating efficiency of the load 1000 .

[0101] 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 startup of the air-conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison result.

[0102] 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 element 10, so that the heat exchange element 10 provides heat 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 first heat exchanger 21 and the heat exchange element 10 through the four-way valve 23 for heat exchange, and then the refrigerant after heat exchange can flow from the first heat exchanger 21 and the heat exchange element 10 into the third heat exchanger 24 for condensation, and 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 for re-compression; in the liquid cooling system 30, the coolant can first be pumped by the water pump 32 and then flow into the heat exchange element 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange, and finally the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0103] See also Figure 1 , Fig.10 and Fig.11 , a control method of an air conditioning system 100 is provided in an embodiment of the present invention. The air conditioning system includes a heat exchanger 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 exchanger 10, and 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, and the control method includes: Step 011: Obtain the demand state and ambient temperature of the load 1000; Step 012: According to the demand state of the load 1000 and the ambient temperature, the liquid cooling system 30 and the air cooling system 20 are controlled to perform thermal management on the load 1000.

[0104] In this way, the liquid cooling system 30 and the air cooling system 20 are connected using the heat exchanger 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 to 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, thereby improving the overall heat dissipation efficiency of the air conditioner.

[0105] The air conditioning system includes a heat exchanger 10, a liquid cooling system 30 and an air cooling system 20. 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 to achieve heat dissipation of the heat generating device. The air cooling system 20 can reduce the temperature of the storage device through the circulation 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 shell system, and the control device 300 includes a processor 310, a memory 320 and a computer program 321. The computer program 321 is stored in the memory 320 and executed by the processor 310, and the computer program 321 includes instructions for executing the control method of the air conditioning system 100.

[0106] Specifically, the processor 310 can obtain the ambient temperature of the load 1000. 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.

[0107] For example, the memory 320 is provided with a first preset temperature and a second preset temperature, and the processor 310 can collect the indoor temperature of the load 1000 in real time, and by comparing the indoor temperature with the first preset temperature and the second preset temperature respectively, according to the comparison result, the processor 310 can control the start 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 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, the processor 310 can determine 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; 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 a heat dissipation demand state, and the air conditioning system 100 starts the heat dissipation mode according to the heat dissipation demand state.

[0108] It should be noted that the first preset temperature is lower than the second preset temperature. For example, the first preset temperature may be 25 degrees Celsius, and the second preset temperature may be 20 degrees Celsius.

[0109] The processor 310 can control the liquid cooling system 30 and the air cooling system 20 to perform thermal management on the load 1000 according to the acquired demand state and ambient temperature of the load 1000 .

[0110] See also Fig.12 In some embodiments, the air cooling system 20 includes a compressor assembly 22, a power assembly 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 and ambient temperature of the load 1000, the liquid cooling system 30 and the air cooling system 20 are controlled to perform thermal management on the load 1000, including: Step 0121: When the load 1000 is in a heat dissipation demand state and the first outdoor ambient temperature is reached, the compressor assembly 22 is controlled to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling to the second heat exchanger 31; Step 0122: When the load 1000 is in a heat dissipation demand state and the second outdoor ambient temperature is reached, the compressor assembly 22 and the power assembly 25 are controlled to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling to the second heat exchanger 31; Step 0123 : When the load 1000 is in a heat dissipation demand state and the third outdoor ambient temperature is reached, the power assembly 25 is controlled to provide cooling to the first heat exchanger 21 and the heat exchange element 10 , so that the heat exchange element 10 provides cooling to the second heat exchanger 31 .

[0111] In this way, at least one of the compressor component 22 and the power component 25 is controlled according to the outdoor temperature of the load 1000 to provide cooling to the heat exchanger 10 and the second heat exchanger 31, so that different components can be selected to provide cooling according to different temperature conditions, which can ensure the heat dissipation efficiency while saving energy consumption.

[0112] Specifically, the first outdoor ambient temperature, the second outdoor ambient temperature and the third outdoor ambient temperature are set in the memory 320, and 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, and can control at least one of the compressor assembly 22 and the power assembly 25 to provide cooling to the heat exchanger 10 and the second heat exchanger 31 according to the comparison result. Among them, the first outdoor ambient temperature, the second outdoor ambient temperature and the third outdoor ambient temperature decrease in magnitude. 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.

[0113] For example, when the load 1000 is in a state of heat dissipation demand and the first outdoor ambient temperature is reached, 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 provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling 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, the refrigerant is condensed by the third heat exchanger 24 and then flows into the heat exchange element 10 and the first heat exchanger 21 for heat exchange. Then, the refrigerant that has undergone heat exchange flows from the first heat exchanger 21 and the heat exchange element 10 through the four-way valve 23 and then enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 for re-compression. In the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchange element 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant that has undergone heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0114] For another example, when the load 1000 is in a state of heat dissipation demand and the second outdoor ambient temperature is reached, it indicates that the indoor temperature is too high and the outdoor temperature is low, and the efficiency of natural heat dissipation for the load 1000 is slow, so that the processor 310 can control the compressor assembly 22 and the power assembly 25 to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling 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, the refrigerant is condensed by the third heat exchanger 24 and then flows into the heat exchanger 10 and the first heat exchanger 21 respectively through the fluorine pump 253 for heat exchange. Then, the refrigerant that has undergone heat exchange flows from the first heat exchanger 21 and the heat exchanger 10 through the four-way valve 23 and then enters the gas-liquid separator 222 for liquid separation, and finally enters the compressor 221 for re-compression. In the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchanger 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange. Finally, the coolant that has undergone heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0115] For another example, when the load 1000 is in a state of heat dissipation demand and the third outdoor ambient temperature is reached, indicating 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, so that the processor 310 can control the power component 25 to provide cooling to the first heat exchanger 21 and the heat exchange element 10, so that the heat exchange element 10 provides cooling to the second heat exchanger 31. In the air cooling system 20, first, the fluorine pump 253 can flow the refrigerant in the pipeline into the heat exchanger 10 and the first heat exchanger 21 for heat exchange, and then the refrigerant after heat exchange flows from the first heat exchanger 21 and the heat exchanger 10 through the four-way valve 23 and enters the gas-liquid separator 222 for liquid separation. Finally, the refrigerant after liquid separation can flow from the gas-liquid separator 222 through the first one-way valve 223 and the four-way valve 23 and enter the third heat exchanger 24, and no longer enters the compressor 221; in the liquid cooling system 30, first, the coolant can be pumped by the water pump 32 and then flow into the heat exchanger 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange, and finally the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.

[0116] See also Fig.13 In some embodiments, the air cooling system 20 includes a compressor assembly 22, a power assembly 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 and ambient temperature of the load 1000, the liquid cooling system 30 and the air cooling system 20 are controlled to perform thermal management on the load 1000, including: Step 0124 : When the load 1000 is in a heating demand state, the compressor assembly 22 is controlled to supply heat to the first heat exchanger 21 and the heat exchange element 10 , so that the heat exchange element 10 provides heat to the second heat exchanger 31 .

[0117] In this way, the compressor assembly 22 is controlled to supply heat to the first heat exchanger 21 and the heat exchange element 10 according to the indoor temperature of the load 1000 , so that the load 1000 can be heated when the indoor temperature is low, thereby improving the operating efficiency of the load 1000 .

[0118] 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 startup of the air-conditioning system 100 and the demand state of the load 1000 can be controlled according to the comparison result.

[0119] 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 element 10, so that the heat exchange element 10 provides heat 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 first heat exchanger 21 and the heat exchange element 10 through the four-way valve 23 for heat exchange, and then the refrigerant after heat exchange can flow from the first heat exchanger 21 and the heat exchange element 10 into the third heat exchanger 24 for condensation, and 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 for re-compression; in the liquid cooling system 30, the coolant can first be pumped by the water pump 32 and then flow into the heat exchange element 10 for heat exchange, and then flow into the second heat exchanger 31 for heat exchange, and finally the coolant after heat exchange can flow back from the second heat exchanger 31 to the water pump 32 for re-pumping.
