Description

Technical Field

[0001] This invention relates to the field of financial technology, and more specifically, to a waste heat utilization system, method, apparatus, storage medium, and electronic device. Background Technology

[0002] As major energy consumers, data centers face increasing pressure to conserve energy under the backdrop of advocating for low-carbon and environmentally friendly practices. To ensure the stable operation of servers, timely heat dissipation is necessary to maintain the data center within a certain temperature and humidity range. However, because the temperature of the hot return air in data centers is generally below 35°C, and the waste heat quality is low, the utilization of this part of the energy has been neglected.

[0003] In related technologies, most of the heat generated by data centers is discharged into the environment through the cooling system, resulting in a certain amount of energy waste and thus a problem of low utilization rate of waste heat from data centers.

[0017] Furthermore, the waste heat utilization method also includes: after obtaining the weather temperature, controlling the heating system to be in a non-working state when the weather temperature is greater than or equal to a first temperature value.

[0018] According to another aspect of the present invention, a waste heat utilization device is also provided for performing the aforementioned waste heat utilization method. The device includes: a first acquisition module for acquiring weather temperature; a first control module for controlling the heating system to be in a working state when the weather temperature is lower than a first temperature value; and a second control module for controlling the opening and closing state of a first valve group to be in a first state and controlling the opening and closing state of a second valve group to be in a second state, wherein the first state indicates that the first valve group is in a state that allows the flowing medium to flow through the heat exchanger, and the second state indicates that the second valve group is in a state that allows the flowing medium to flow through the heat conduction device.

[0034] Example 1

[0035] According to an embodiment of the present invention, an embodiment of a waste heat utilization system is provided. Figure 1 This is a schematic diagram of an optional waste heat utilization system according to an embodiment of the present invention, such as... Figure 1 As shown, the system includes:

[0036] The heating system 10 is connected to the heating pipeline 20 and the data center in the target institution. It is used to absorb the waste heat generated by the data center and heat the flowing medium in the heating pipeline 20 through the waste heat.

[0037] The heating pipeline 20 is connected to the heat exchanger 30 and the heat transfer device 40 respectively;

[0038] Heat exchanger 30 is connected to the cooling system of generator 110 and is used to provide heat to the cooling system through the heat of the flowing medium, wherein generator 110 is an emergency power source for the data center.

[0039] Heat conduction device 40 is used to provide heat to areas within the target facility other than the data center through the heat of the flowing medium;

[0040] The first valve group 50 is connected between the heating pipeline 20 and the heat exchanger 30 and is used to control the flow rate of the flowing medium through the heat exchanger 30.

[0041] The second valve assembly 60 is connected between the heating pipeline 20 and the heat conduction device 40, and is used to control the flow rate of the flowing medium through the heat conduction device 40;

[0042] The control system, connected to the heating system 10, the first valve group 50, and the second valve group 60, is used to control at least one of the following states based on the weather temperature: the operating state of the heating system 10, the opening and closing state of the first valve group 50, and the opening and closing state of the second valve group 60.

[0043] Optionally, the aforementioned target organization can be a financial institution or other organizations. Target organizations include data centers and other areas, such as employee workspaces and rest areas. For example... Figure 1 As shown, the data center contains multiple server racks and air conditioners. The servers in the racks generate heat during operation, thus creating a [heat field effect]. Figure 1The diagram shows a hot passage. A refrigerant flows inside the heating system 10, which is connected to a data center, allowing the refrigerant to absorb waste heat from the hot passage. Furthermore, the heating system 10 is also connected to a heating pipe 20, which contains a flowing medium; in this embodiment, the flowing medium can be water. The heating system 10 can use waste heat to heat the flowing medium within the heating pipe 20.

[0044] Furthermore, the heating pipeline 20 is connected to the heat exchanger 30 and the heat conduction device 40 respectively. The flowing medium in the heating pipeline 20 can flow through the heat exchanger 30 and the heat conduction device 40 to provide usable heat to the heat exchanger 30 and the heat conduction device 40. For example, Figure 1 As shown, a circulating water pump 120 can also be installed on the heating pipeline 20 to drive the flowing medium to circulate in the heating pipeline 20.

[0045] Optionally, data centers typically use generator 110 as an emergency power source, which can be a diesel generator. To ensure that generator 110 can start quickly when the mains power supply is interrupted, the coolant in its cooling system needs to be maintained at around 40°C. Therefore, the coolant needs to be heated under normal conditions. Thus, in this embodiment, heat exchanger 30 is connected to the cooling system of generator 110, so that heat exchanger 30 can provide heat to the cooling system through the heat of the flowing medium.

[0046] Optionally, the aforementioned heat conduction device 40 may be a heat conduction coil or other device with heat conduction function. The heat conduction device 40 may be arranged in areas other than the data center within the target organization, such as in the corridors or office areas of the target organization, so that when the flowing medium flows through the heat conduction device 40, it can provide heat to the area where the heat conduction device 40 is arranged.

[0047] Since the heat required in areas outside the data center within the target facility is lower than that of the generator 110's cooling system, in this embodiment, as... Figure 1 As shown, the heat exchanger 30 can be arranged upstream of the heat transfer device 40 according to the flow direction of the flowing medium, so that the heat exchanger 30 can utilize the heat in the flowing medium before the heat transfer device 40. Figure 1 The arrows in the diagram are used to indicate the direction of refrigerant or fluid flow.

[0048] Furthermore, in order to better control the degree of heat utilization by the heat exchanger 30 and the heat transfer device 40, the aforementioned first valve group 50 and second valve group 60 can be provided. For example, the first valve group 50 may include valves respectively provided at the outlet and inlet of the heat exchanger 30, and the second valve group 60 may include valves respectively provided at the outlet and inlet of the heat transfer device 40.

[0049] Furthermore, since the auxiliary heat required by the cooling system of generator 110 varies with different weather temperatures, and the auxiliary heat required by areas within the target facility other than the data center also varies, for example, in hot weather, the cooling system can maintain the coolant temperature within the normal range using the ambient temperature, and areas within the target facility other than the data center do not require heat supply. Therefore, the operating status of the heating system 10, the first valve group 50, and the second valve group 60 needs to be adaptively adjusted according to the weather temperature.

[0050] Optionally, in this embodiment, to reduce labor costs, a control system can be installed in the waste heat recovery system. This control system controls the heating system 10, the first valve group 50, and the second valve group 60 based on the weather temperature. For example, in hot weather, the heating system 10 is shut down; in cold weather, it is turned on. The first valve group 50 and the second valve group 60 are controlled to allow the flowing medium to pass through the heat exchanger 30 and the heat transfer device 40. It should be noted that the control system can not only control the opening and closing states of the first valve group 50 and the second valve group 60, but also adjust the opening degree of each valve in both groups.

[0051] Among them, such as Figure 1 As shown, a first temperature sensor 130 can be installed in an area other than the data center, a second temperature sensor 140 for detecting the coolant can be installed in the cooling system, and a third temperature sensor 150 for detecting the temperature of the flowing medium can be installed on the heating pipeline 20. The control system is connected to the first temperature sensor 130, the second temperature sensor 140 and the third temperature sensor 150 remotely and wirelessly, so that the control system can achieve better control based on the weather temperature, combined with the area temperature, coolant temperature and flowing medium temperature.

[0052] It is noteworthy that, in the above process, by setting up the heating system 10, the waste heat in the data center is effectively transferred to the heating pipes 20, thereby achieving auxiliary cooling of the data center. By connecting the heating pipes 20 to the heat exchanger 30 and the heat transfer device 40, the waste heat of the data center is effectively utilized, improving the waste heat utilization rate and avoiding the high energy consumption problem of using electric heating devices to heat the cooling system of the generator 110 in related technologies. Furthermore, by setting up a control system, the working state of the heating system 10 and the opening and closing state of the valves are controlled according to the ambient temperature, thereby effectively controlling the flow direction of the flowing medium, improving the applicability of the waste heat utilization system under different ambient temperatures, and further improving the waste heat utilization rate.

[0053] Therefore, the solution provided in this application achieves the goal of using the waste heat of the data center to provide heat to other areas or devices, thereby realizing the technical effect of improving the waste heat utilization rate and solving the technical problem of low waste heat utilization rate of the existing technology.

[0054] In an optional embodiment, the heating system 10 further includes: a first heating subsystem 11 connected to a second heating subsystem 12 for absorbing waste heat generated by the data center; and a second heating subsystem 12 for heating the flowing medium using the waste heat.

[0055] Optionally, the first heating subsystem 11 includes a heat pipe terminal evaporator 111, a heat pipe gas line 112, a heat pipe liquid line 113, an electric valve 114, and a first heat exchange device 115. Wherein, for example... Figure 1 As shown, the heat pipe terminal evaporator 111 is installed in the form of a suspended ceiling above the hot aisle of the data center, without occupying the floor space of the data center. Liquid refrigerant vaporizes within the heat pipe terminal evaporator 111 by absorbing waste heat generated by the data center. A heat pipe gas line 112 connects to the heat pipe terminal evaporator 111 and is used to transport the refrigerant vaporized into gas within the heat pipe terminal evaporator 111 to the first heat exchanger 115. The first heat exchanger 115 connects to the heat pipe gas line 112 and the second heating subsystem 12, and is used to condense and liquefy the gaseous refrigerant to absorb heat, i.e., absorb waste heat from the data center, and use the absorbed waste heat to heat the refrigerant in the second heating subsystem 12. A heat pipe liquid line 113 connects between the first heat exchanger 115 and the heat pipe terminal evaporator 111, and is used to transport the condensed and liquefied refrigerant to the heat pipe terminal evaporator 111. The liquefied refrigerant completes circulation under gravity, eliminating the need for an additional water pump. The electric valve 114 is used to control the flow rate of refrigerant in the heat pipe liquid line 113, so as to reduce the use of the heating system 10 when the overall energy efficiency of the heating system 10 is lower than that of the air conditioning energy efficiency of the data center.

[0056] Among them, such as Figure 1 As shown, the heat pipe terminal evaporator 111 located in the hot aisle ceiling of the computer room, driven by the data center air conditioner, first passes through the heat pipe terminal evaporator 111, where the heat pipe terminal evaporator 111 absorbs some heat, and then the air conditioner cools it to form a cold aisle, which can effectively reduce the energy consumption of the air conditioner.

[0057] Optionally, the second heating subsystem 12 includes a second heat exchanger 121, a compressor 122, and a throttling valve 123. Refrigerant flows within each device in the second heating subsystem 12. The compressor 122 is connected to the first heat exchanger 115 and is used to compress the refrigerant heated by the first heat exchanger 115 into a high-temperature, high-pressure gaseous refrigerant. This allows the low-grade waste heat (around 35°C) to be raised to above 45°C under the action of a reverse Carnot cycle. The second heat exchanger 121 is connected to the compressor 122 and the heating pipeline 20, and is used to absorb the heat from the compressed gaseous refrigerant and utilize this heat to heat the flowing medium in the heating pipeline 20. The throttling valve 123 is connected between the second heat exchanger 121 and the first heat exchanger 115 and is used to control the refrigerant flow rate.

[0058] It should be noted that by setting up a first heating subsystem 11 and a second heating subsystem 12, the waste heat of the data center is effectively converted. The first heating subsystem 11 uses gravity difference as a drive to inject liquid refrigerant into the evaporator 111 at the end of the heat pipe, delivering it to the outside of the data center for heat dissipation without consuming additional heat. A natural pump driven by temperature difference is used to achieve continuous cyclic cooling for the first heating subsystem 11. The second heating subsystem 12 employs compression heat pump technology to effectively enhance the heat carried by the refrigerant, thereby effectively expanding the scope of waste heat utilization in the data center, extending its usage time, and avoiding the problem in related technologies where the cooling system of the generator 110 requires more heat than the waste heat of the data center, leading to difficulty in utilization.

[0059] In one optional embodiment, the first valve group 50 includes: a first inlet valve 51 connected between the heating pipeline 20 and the inlet of the heat exchanger 30, for controlling the flow rate of the flowing medium into the heat exchanger 30; a first outlet valve 52 connected between the heating pipeline 20 and the outlet of the heat exchanger 30, for controlling the flow rate of the flowing medium out of the heat exchanger 30; and a first bypass valve 53 disposed on the heating pipeline 20 and connected between the inlet of the first inlet valve 51 and the outlet of the first outlet valve 52.

[0060] Optional, such as Figure 1 As shown, the first bypass valve 53 is used to divert the flowing medium into the heat exchanger 30. When the first bypass valve 53 is closed and the first inlet valve 51 and the first outlet valve 52 are open, the flow rate through the heat exchanger 30 is at its maximum. When the first bypass valve 53 is open and both the first inlet valve 51 and the first outlet valve 52 are open, the flow rate through the heat exchanger 30 decreases. When the first bypass valve 53 is open and the first inlet valve 51 and the first outlet valve 52 are closed, the flowing medium does not flow through the heat exchanger 30.

[0061] It should be noted that by setting the first inlet valve 51 and the first bypass valve 53, the flow rate of the flowing medium passing through the heat exchanger 30 can be effectively controlled.

[0062] In one optional embodiment, the second valve assembly 60 includes: a second inlet valve 61 connected between the heating pipeline 20 and the inlet of the heat conduction device 40, for controlling the flow rate of the flowing medium into the heat conduction device 40; a second outlet valve 62 connected between the heating pipeline 20 and the outlet of the heat conduction device 40, for controlling the flow rate of the flowing medium out of the heat conduction device 40; and a second bypass valve 63 disposed on the heating pipeline 20 and connected between the inlet of the second inlet valve 61 and the outlet of the second outlet valve 62.

[0063] Optional, such as Figure 1 As shown, the second bypass valve 63 is used to divert the flow of the medium flowing into the heat transfer device 40. When the second bypass valve 63 is closed and the second inlet valve 61 and the second outlet valve 62 are open, the flow rate through the heat transfer device 40 is at its maximum. When the second bypass valve 63 is open and both the second inlet valve 61 and the second outlet valve 62 are open, the flow rate through the heat transfer device 40 decreases. When the second bypass valve 63 is open and the second inlet valve 61 and the second outlet valve 62 are closed, the medium does not flow through the heat transfer device 40.

[0064] It should be noted that by setting the second inlet valve 61 and the second bypass valve 63, the flow rate of the flowing medium passing through the heat conduction device 40 can be effectively controlled.

[0065] In an optional embodiment, the waste heat recovery system further includes a heat dissipation device 70 connected to the heating pipeline 20 for dissipating the heat of the flowing medium to the outside of the target structure.

[0066] When there is excessive waste heat in the data center, there may be residual heat remaining even after supplying heat to the heat exchanger 30 and heat transfer device 40. Therefore, a heat dissipation device 70 can be installed in the waste heat utilization system to dissipate the aforementioned residual heat. Optionally, the heat dissipation device 70 can be a closed-loop cooling tower. For example... Figure 1 As shown, the heat dissipation device 70 is located downstream of the heat conduction device 40 according to the flow direction of the fluid medium, so as to avoid the phenomenon that the heat dissipation is insufficient due to heat dissipation first.

[0067] It should be noted that by setting up the heat dissipation device 70, excess heat can be effectively treated, thereby improving the applicability of the waste heat utilization system.

[0068] In an optional embodiment, the waste heat utilization system further includes: a third inlet valve 80, connected between the heating pipeline 20 and the heat dissipation device 70, for controlling the flow rate of the flowing medium into the heat dissipation device 70; a third bypass valve 90, disposed on the heating pipeline 20, and the inlet of the third bypass valve 90 is connected to the inlet of the third inlet valve 80; wherein, the control system is connected to the third inlet valve 80 and the third bypass valve 90, and the control system is used to control the opening and closing states of the third inlet valve 80 and the third bypass valve 90.

[0069] Optional, such as Figure 1 As shown, the third bypass valve 90 is used to divert the flow of the medium flowing into the heat dissipation device 70. When the third bypass valve 90 is closed and the third inlet valve 80 is open, the flow rate through the heat dissipation device 70 is at its maximum. When both the third bypass valve 90 and the third inlet valve 80 are open, the flow rate through the heat dissipation device 70 decreases. When the third bypass valve 90 is open and the third inlet valve 80 is closed, the medium does not flow through the heat dissipation device 70.

[0070] Furthermore, in order to reduce labor costs, the opening and closing states of the third inlet valve 80 and the third bypass valve 90 can be controlled by the control system to determine the timing and extent of heat dissipation in the flowing medium.

[0071] It should be noted that by setting the third inlet valve 80 and the third bypass valve 90, the flow rate of the medium flowing through the heat dissipation device 70 can be effectively controlled. By using the control system to control the third inlet valve 80 and the third bypass valve 90, labor costs can be effectively reduced and control timeliness can be improved.

[0072] In one alternative embodiment, such as Figure 1 As shown, the heating system 10 also includes an electric heating device 100 connected to the cooling system for providing heat to the cooling system. The control system is connected to the electric heating device 100 and is used to control the operating status of the electric heating device 100.

[0073] Optionally, since the waste heat from the data center may not be sufficient to keep the coolant in the cooling system warm in cold weather, an electric heating device 100 can be installed to provide auxiliary heat to the cooling system, ensuring that the coolant temperature remains stable. The control system can control the start and stop of the electric heating device 100.

[0074] It should be noted that by setting up the electric heating device 100, the temperature of the coolant in the cooling system can be effectively guaranteed, thereby improving the stability of the generator 110's operation.

[0075] Therefore, the solution provided in this application achieves the goal of using the waste heat of the data center to provide heat to other areas or devices, thereby realizing the technical effect of improving the waste heat utilization rate and solving the technical problem of low waste heat utilization rate of the existing technology.

[0076] Example 2

[0077] According to an embodiment of the present invention, an embodiment of a waste heat utilization method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0078] Figure 2 This is a schematic diagram of an optional waste heat utilization method according to an embodiment of the present invention, such as... Figure 2 As shown, this method can be applied to the control system of the waste heat utilization system in Example 1, and the method includes the following steps:

[0079] Step S201: Obtain the weather temperature.

[0080] Optionally, the weather temperature can be sensed by the control system based on temperature sensors installed outdoors, or it can be obtained by the control system through a network connection.

[0081] Step S202: When the ambient temperature is lower than the first temperature value, control the heating system to be in working state.

[0082] Optionally, the first temperature value can be preset by the user. When the ambient temperature is lower than the first temperature, it is determined that the cooling system and areas within the target facility other than the data center require more heat. In this case, the control system can activate the heating system. Specifically, the control system can activate the various devices in the first heating subsystem and the various devices in the second heating subsystem.

[0083] Step S203: Control the opening and closing state of the first valve group to be in the first state, and control the opening and closing state of the second valve group to be in the second state. The first state indicates that the first valve group is in a state that allows the flowing medium to flow through the heat exchanger, and the second state indicates that the second valve group is in a state that allows the flowing medium to flow through the heat conduction device.

[0084] To effectively provide heat to the cooling system and areas within the target facility other than the data center, the control system can control the opening and closing state of the first valve group to a first state, allowing the flowing medium in the heating pipeline to flow through the heat exchanger, and control the opening and closing state of the second valve group to a second state, allowing the flowing medium in the heating pipeline to flow through the heat transfer device. For example, the control system can control the first bypass valve to close and the first inlet valve and the second outlet valve to open, and control the second bypass valve to close and the second inlet valve and the second outlet valve to open.

[0085] Based on the scheme defined in steps S201 to S203 above, it can be understood that in this embodiment of the invention, the method of using the waste heat of the data center to provide heat to other areas or devices is adopted. By obtaining the weather temperature, when the weather temperature is less than a first temperature value, the heating system is controlled to be in working state, the opening and closing state of the first valve group is controlled to be in a first state, and the opening and closing state of the second valve group is controlled to be in a second state. The first state indicates that the first valve group is in a state that allows the flowing medium to flow through the heat exchanger, and the second state indicates that the second valve group is in a state that allows the flowing medium to flow through the heat conduction device.

[0086] It is noteworthy that, in the above process, by setting up a heating system, waste heat from the data center is effectively transferred to the heating pipelines, thereby achieving auxiliary cooling of the data center. By connecting the heating pipelines to heat exchangers and heat transfer devices, the waste heat from the data center is effectively utilized, improving the waste heat utilization rate and avoiding the high energy consumption problem associated with using electric heating devices to heat the generator cooling system in related technologies. Furthermore, by setting up a control system, the operating status of the heating system and the opening and closing status of valves are controlled according to the ambient temperature, thereby effectively controlling the flow direction of the fluid medium, improving the applicability of the waste heat utilization system under different ambient temperatures, and further improving the waste heat utilization rate.

[0087] Therefore, the solution provided in this application achieves the goal of using the waste heat of the data center to provide heat to other areas or devices, thereby realizing the technical effect of improving the waste heat utilization rate and solving the technical problem of low waste heat utilization rate of the existing technology.

[0088] In one optional embodiment, the control system can determine whether the weather temperature is lower than a second temperature value if the weather temperature is lower than a first temperature value. If the weather temperature is lower than the second temperature value, the control system will close the third inlet valve and open the third bypass valve. The third inlet valve is connected between the heating pipeline and the heat dissipation device to control the flow rate of the flowing medium into the heat dissipation device. The third bypass valve is located on the heating pipeline, and its inlet is connected to the inlet of the third inlet valve. The heat dissipation device is connected to the heating pipeline. The second temperature value is lower than the first temperature value.

[0089] Optionally, the second temperature value can be preset by the user. When the ambient temperature is lower than the second temperature, it can be determined that the weather is cold. In this case, it is determined that after the waste heat from the data center is supplied to the cooling system and areas within the target facility other than the data center, there will be no excess heat remaining. Therefore, the control system can control the third inlet valve to be closed and the third bypass valve to be open to avoid using a heat dissipation device for heat dissipation. In this case, the flowing medium in the heating pipeline flows sequentially through the heat exchanger and the heat conduction device, but does not flow through the heat dissipation device.

[0090] It should be noted that by controlling the third inlet valve and the third bypass valve when the weather temperature is relatively low, excessive heat dissipation is avoided, thereby improving the utilization rate of waste heat.

[0091] In one alternative embodiment, after determining whether the weather temperature is less than the second temperature value, the control system can control the third inlet valve to be in the open state and control the third bypass valve to be in the closed state if the weather temperature is greater than or equal to the second temperature value.

[0092] Optionally, if the ambient temperature is greater than or equal to the second temperature value but less than the first temperature value, it can be determined that the ambient temperature is relatively hot. In this case, it is determined that after the waste heat from the data center is supplied to the cooling system and areas within the target facility other than the data center, there will still be excess heat remaining, which needs to be discharged into the atmosphere. Therefore, the control system can control the third inlet valve to be in the open state and control the third bypass valve to be in the closed state to dissipate heat through the heat dissipation device. In this case, the flowing medium in the heating pipeline flows sequentially through the heat exchanger, the heat conduction device, and the heat dissipation device.

[0093] Furthermore, the control system can also detect the temperature of the flowing medium in real time, and adjust the opening of the third inlet valve and the third bypass valve according to the temperature of the flowing medium. For example, when the temperature of the flowing medium is greater than the third temperature value, the opening of the third inlet valve is adjusted to the maximum and the opening of the third bypass valve is adjusted to the minimum, so as to maximize the flow rate of the flowing medium through the heat dissipation device. When the temperature of the flowing medium is less than or equal to the third temperature value and greater than the fourth temperature value, the opening of the third inlet valve is adjusted to the maximum and the opening of the third bypass valve is adjusted to half opening, so as to reduce the flow rate of the flowing medium through the heat dissipation device. When the temperature of the flowing medium is less than or equal to the fourth temperature value, the opening of the third inlet valve is adjusted to the maximum and the opening of the third bypass valve is adjusted to the maximum, so as to further reduce the flow rate of the flowing medium through the heat dissipation device.

[0094] It should be noted that, under relatively high weather conditions, controlling the third inlet valve and the third bypass valve effectively determines the timing of heat dissipation for the flowing medium, thereby improving the waste heat utilization rate.

[0095] In one optional embodiment, after controlling the opening and closing state of the second valve group to be in the second state, the control system can obtain the liquid temperature value of the coolant in the cooling system, and then control the electric heating device to start when the liquid temperature value is less than the preset temperature value. The electric heating device is connected to the cooling system and is used to provide heat to the cooling system.

[0096] Optionally, the control system can acquire the liquid temperature of the coolant in the cooling system in real time. When the liquid temperature is lower than the preset temperature, it is determined that the waste heat of the data center is insufficient to meet the temperature requirements of the coolant. At this time, the control system controls the electric heating equipment to start to assist in heating the coolant.

[0097] It should be noted that by controlling the electric heating equipment according to the coolant temperature, the stability of the generator operation is ensured.

[0098] In one alternative embodiment, after acquiring the weather temperature, the control system can control the heating system to be in a non-operating state if the weather temperature is greater than or equal to a first temperature value.

[0099] Optionally, if the weather temperature is greater than or equal to the first temperature value, it can be determined that the weather is hot. In this case, it is determined that the generator and the area outside the data center in the target unit do not need to supply heat, and the energy consumption of the heating system to absorb waste heat from the data center is higher than the energy consumption of the air conditioner in the data center. In this case, the control system controls the heating system to be in a non-working state to reduce the overall energy consumption of the data center.

[0100] It should be noted that by controlling the shutdown of the heating system when the weather temperature is relatively high, the adaptability of the method provided in this application to weather temperature is improved.
