[0033] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0034] Reference Figure 1 This invention discloses an integrated energy system, which may include:

[0035] Wastewater tank 1 is used to store wastewater.

[0036] Heat pump unit 2 is used to heat the water discharged from the sewage tank 1.

[0037] Centrifuge unit 3 is used to cool the water discharged from the sewage tank 1.

[0038] Energy storage tank 4 is connected to both the heat pump unit 2 and the centrifugal chiller unit 3, and is used for energy storage or release. The connection point between the heat pump unit 2 and the energy storage tank 4 serves as the heat source output end, and the connection point between the centrifugal chiller unit 3 and the energy storage tank 4 serves as the cold source output end.

[0039] Cooling pipe 5 is laid at the data center.

[0040] The plate heat exchanger 6 is connected to the sewage tank 1, the energy storage tank 4 and the centrifuge unit 3 respectively, and is used to exchange heat with the water in the cooling pipe 5 to cool the data center.

[0041] In this embodiment of the invention, the system may include equipment such as a sewage tank 1, a heat pump unit 2, a centrifugal chiller unit 3, an energy storage tank 4, cooling pipes 5, and a plate heat exchanger 6. For example, the heat pump unit 2 may be a water source heat pump unit 2, and the centrifugal chiller unit 3 may be a centrifugal chiller unit, etc. For instance, the sewage tank 1 may be installed underground, reducing the roof load of the system. In one example, during system cooling, water from the sewage tank 1 is directed to the centrifugal chiller unit 3, which cools the sewage and converts it into a cold source. This cold source is output from the cold source output end for user use, or it may pass through the plate heat exchanger 6 to exchange heat with the water in the cooling pipes 5 to cool the data center. The energy storage tank 4 stores or releases cold at different times to achieve the purpose of energy saving in system cooling.

[0042] In another example, when the system is heating, water from wastewater tank 1 is directed to heat pump unit 2. Heat pump unit 2 heats the wastewater, converting it into a heat source, which is then output from the heat source output terminal for user use. Energy storage tank 4 stores or releases heat at different times to achieve energy savings in the system's heating operation. Furthermore, the water-directed plate heat exchanger 6 in wastewater tank 1 uses the water from tank 1 as a cold source, flowing through cooling pipes 5 into the data center to cool it down. The heat source circulating out of the data center is then directed to heat pump unit 2. Therefore, utilizing the waste heat from the data center effectively reduces the energy consumption generated by heat pump unit 2 during heating.

[0043] To ensure the system's operational stability, it can be configured with two units, functioning as two independent integrated energy systems. These systems can operate independently, providing a backup system in case of a failure in one, thus ensuring overall stability. The equipment selection and quantity within this system are chosen based on the user's load requirements.

[0044] In summary, by using wastewater energy as a system input source and employing integrated collaboration with heat pump unit 2, centrifugal chiller unit 3, and plate heat exchanger 6, the system can provide users or data center IT equipment with various energy needs, including cooling and heating, ensuring the safe and stable operation of the data center. Furthermore, it enables the recovery and reuse of heat generated by the data center, preventing the conversion of large amounts of electrical energy consumption into heat dissipation that exacerbates the greenhouse effect and reducing regional energy application costs. Simultaneously, it allows for the sharing of power supply equipment between the energy station and the data center, achieving multi-energy coordinated supply and comprehensive cascade utilization of energy within the urban area.

[0045] In one optional embodiment of the invention, the system further includes a water replenishment tank 7, which is connected to the heat pump unit 2 and the centrifugal chiller unit 3.

[0046] In this embodiment of the invention, the system may further include a water replenishment tank 7, which is connected to the heat pump unit 2 and the centrifugal unit 3 via pipelines. For example, the water in the water replenishment tank 7 is supplied by the municipal water supply. The water replenishment tank 7 serves as a backup water supply tank. When the sewage tank 1 is under maintenance, the water in the water replenishment tank 7 can be used as the circulating water of the system and introduced into the centrifugal unit 3 or the heat pump unit 2 for heat or cold energy conversion.

[0047] In one optional embodiment of the invention, the system further includes a heat source tower 8, which is connected to a water replenishment tank 7 and is used to cool or heat the water discharged from the water replenishment tank 7.

[0048] In this embodiment of the invention, the system may further include a heat source tower 8. In one example, the heat source tower 8 may be connected to a water replenishment tank 7, which can initially cool or heat the water flowing out of the water replenishment tank 7 to compensate for the unreliability and intermittency of the water in the water replenishment tank 7, thereby facilitating the improvement of the operational stability of the centrifugal chiller unit 3 and the heat pump unit 2. In another example, the heat source tower 8 may also be connected to a sewage tank 1, which can then initially cool or heat the water flowing out of the sewage tank 1 to compensate for the unreliability and intermittency of the water in the sewage tank 1.

[0049] In an optional embodiment of the invention, an electrode boiler 9 is further connected at the connection point between the heat pump unit 2 and the energy storage tank 4 to provide a heat source to the heat source output end.

[0050] In this embodiment of the invention, the system may further include an electrode boiler 9, which can serve as a backup heat source in extreme weather conditions to meet the user's heat load requirements. For example, the electrode boiler 9 can be connected at the connection point between the heat pump unit 2 and the energy storage tank 4. When operating, the electrode boiler 9 can provide heat to the heat source output terminal.

[0051] Reference Figure 2 This invention discloses a control method applied to an integrated energy system, wherein the integrated energy system further includes control equipment, and the control method may include:

[0052] Step S21: The control device determines the operating model of the system based on time. The operating model includes a first mode, a second mode, and a third mode.

[0053] If the running model is in the first mode, then execute step S22; if the running model is in the second mode, then execute step S23; if the running model is in the third mode, then execute step S24.

[0054] In this embodiment of the invention, the system may further include a control device, which may be a controller, a microcontroller, or a PCB, etc. The control device is electrically connected to the electrical equipment in the system and coordinates the operation of each device in the system. For example, the system's operating model can be determined by acquiring time through the control device. Throughout the year, the data center always requires cooling, while the user end can be divided into three scenarios depending on the season: cooling supply in summer, heating supply in winter, and no energy supply required in spring and autumn. By combining the data center and the energy station, the system's operating model can include a first mode, a second mode, and a third mode.

[0055] For example, the four seasons can be divided according to meteorological data. For instance, according to meteorological departments, spring is typically from March to August, summer from June to August, autumn from September to November, and winter from December to February of the following year. In another example, the four seasons can be divided based on the annual temperature of the city area where the system is located. For example, by collecting average temperatures over a continuous period of 5-7 days, summer begins when the average temperature remains consistently above 22°C, autumn begins when the average temperature drops from 22°C to 10°C, winter begins when the average temperature remains consistently below 10°C, and spring begins when the average temperature rises from 10°C to 22°C. In yet another example, the four seasons can also be divided by operators based on the energy needs of the user's end.

[0056] Therefore, the first mode can be defined as the system providing cooling to users and data centers in summer, the second mode as the system providing heat to users and cooling to data centers in winter, and the third mode as the system providing cooling to users and data centers in spring and autumn.

[0057] According to the operating model, energy control operations are performed during the time periods corresponding to the power levels; the power time periods include: off-peak periods, peak periods, and peak periods.

[0058] In this embodiment of the invention, during the summer cooling system, the operation of related equipment can be controlled by time periods. For example, the energy system can be adjusted at 24-hour intervals based on the power level corresponding to the urban power grid. The power level is determined by dividing the urban power grid into three levels based on the daily 24-hour load changes: off-peak, peak, and peak periods. Therefore, according to the power level, each 24-hour period can be divided into off-peak, peak, and peak periods. For example, 8:00 AM to 9:00 PM is designated as the peak period. Within the peak period, 4:00 PM to 5:00 PM and 8:00 PM to 9:00 PM are designated as peak periods. 9:00 PM to 8:00 AM the following day is designated as the off-peak period. Since the electricity pricing standard is lowest during the off-peak period, the energy storage tank 4 can be used as a peak-shaving and valley-filling device under different operating models, thereby achieving energy saving and reducing system operating costs.

[0059] Step S22: According to the first mode, perform energy control operations within the time period corresponding to the power level.

[0060] Step S22 may also include:

[0061] According to the first mode, during periods of low electricity demand, the centrifugal chiller 3 provides cooling capacity to the plate heat exchanger 6 and the cold source output terminal, and the energy storage tank 4 stores cold energy; during periods of high electricity demand, the energy storage tank 4 provides cooling capacity to the plate heat exchanger 6, and the centrifugal chiller 3 provides cooling capacity to the cold source output terminal; during periods of peak electricity demand, the energy storage tank 4 provides cooling capacity to the plate heat exchanger 6 and the cold source output terminal.

[0062] In this embodiment of the invention, during summer, the system can be adjusted to operate in a first mode via control equipment. According to the first mode, during off-peak electricity periods, water from the sewage tank 1 is pumped to the centrifuge unit 3. The centrifuge unit 3 cools the sewage, and the resulting cold source flows to the plate heat exchanger 6, the cold source output end, and the energy storage tank 4. The cold source flowing to the plate heat exchanger 6 exchanges heat with the cooling pipes 5 to cool the data center. The cold source at the cold source output end can flow to the user end for use, such as in radiant air conditioning systems. The energy storage tank 4 stores cold based on the cold source. During peak electricity periods, the energy storage tank 4 stops storing cold and provides cooling to the plate heat exchanger 6 to cool the data center. The centrifuge unit 3 only needs to convert the cold source for user use. During peak electricity periods, the centrifuge unit 3 stops operating. At this time, the energy storage tank 4 provides cooling to the plate heat exchanger 6 and also provides cooling to the user end through the cold source output end.

[0063] Step S23: According to the second mode, perform energy control operations within the time period corresponding to the power level.

[0064] Step S23 may also include:

[0065] According to the second mode, during periods of low electricity demand, the heat pump unit 2 provides heat to the heat source output terminal, and the energy storage tank 4 stores heat; during periods of high electricity demand, the heat pump unit 2 provides heat to the heat source output terminal, and the energy storage tank 4 stops storing heat; during periods of peak electricity demand, the energy storage tank 4 provides heat to the heat source output terminal; wherein, the sewage tank 1 provides cooling capacity to the plate heat exchanger 6.

[0066] In this embodiment of the invention, during winter, the system can be adjusted to operate in a second mode via control equipment. According to this second mode, during off-peak electricity periods, water from sewage tank 1 is pumped to heat pump unit 2. Heat pump unit 2 heats the sewage, and the converted heat flows to the heat source output terminal and energy storage tank 4 respectively. The heat source output terminal supplies heat to the user end, while energy storage tank 4 stores heat based on the heat source. During peak electricity periods, heat pump unit 2 only needs to convert the heat source for user end use, and energy storage tank 4 stops storing heat. During peak electricity periods, heat pump unit 2 stops working, and energy storage tank 4 provides heat to the user end. Since the data center needs cooling year-round, it does not need to draw heat from heat pump unit 2. Therefore, during winter, plate heat exchanger 6 is directly connected to sewage tank 1, and the water from sewage tank 1 acts as a cold source, cooling the data center through plate heat exchanger 6. By directing the heat source circulating out of the data center to the inlet of heat pump unit 2, the waste heat of the data center can be utilized, reducing the energy consumption of heat pump unit 2 during heating and improving heating efficiency. This achieves comprehensive cascade utilization of energy in urban areas.

[0067] Step S24: According to the third mode, perform energy control operations within the time period corresponding to the power level.

[0068] Step S24 may also include:

[0069] According to the third mode, during periods of low electricity demand, the energy storage tank 4 stores cold energy, and the centrifuge unit 3 provides cooling capacity to the energy storage tank 4 and the plate heat exchanger 6. During periods of high electricity demand and peak demand, the energy storage tank 4 and the sewage tank 1 provide cooling capacity to the plate heat exchanger 6.

[0070] In this embodiment of the invention, during spring and autumn, the user end does not require energy supply; only cooling of the data center is needed. The system can be adjusted to operate in a third mode via control equipment. According to the third mode, during off-peak electricity periods, centrifugal chiller 3 can operate to switch the cold source, flowing to the energy storage tank 4 and plate heat exchanger 6. The energy storage tank 4 stores cold, and the plate heat exchanger 6 cools the data center through heat exchange. During peak electricity periods, the energy storage tank 4 stops storing cold and provides cooling to the plate heat exchanger 6. For example, if the peak electricity periods are too long and the energy storage tank 4 cannot meet the cooling demand during that time, water from the wastewater tank 1 can be used as a cold source flowing to the plate heat exchanger 6 after a period of time.

[0071] All the connections mentioned above can be made by laying pipes. Furthermore, the flow direction of the circulating water in the system can be adjusted by valves, such as solenoid valves. The control equipment is electrically connected to the corresponding solenoid valve, and the control equipment outputs a signal to control the opening and closing of the solenoid valve, thereby changing the flow direction of the circulating water.

[0072] In summary, by using wastewater energy as the system input source and employing integrated collaboration with heat pump unit 2, centrifugal chiller unit 3, and plate heat exchanger 6, the system can provide users or data center IT equipment with various energy needs, including cooling and heating, ensuring the safe and stable operation of the data center. Furthermore, it can recover and reuse the heat generated by the data center, preventing the conversion of large amounts of electrical energy consumption into heat dissipation that exacerbates the greenhouse effect. Different equipment operation models are set according to different seasons, and the operation of relevant equipment in the system is controlled in different time periods under the same operation model. Peak shaving and valley filling are achieved through energy storage tank 4, thereby achieving energy saving and reducing system operating costs. Simultaneously, the energy station and data center share energy supply equipment, realizing multi-energy coordinated supply and comprehensive cascade utilization of energy in urban areas.

[0073] In an optional embodiment of the invention, the control method further includes:

[0074] The system checks whether the wastewater tank 1 meets the preset maintenance conditions. If it does, the control device controls the water in the water replenishment tank 7 to be discharged to replenish the circulating water in the system.

[0075] In this embodiment of the invention, an electromagnetic valve can be installed at the outlet of the sewage tank 1, and the electromagnetic valve is controlled by a control device. For example, the preset detection condition can be a closing signal representing the corresponding electromagnetic valve in the control device. If the control device outputs a control signal to close the electromagnetic valve, it proves that the outlet of the sewage tank 1 has been closed, meeting the maintenance conditions. To ensure the water supply of the system, the water from the replenishment tank 7 can be controlled to exit. At this time, the sewage tank 1 can be inspected and maintained.

[0076] In an optional embodiment of the invention, the control method further includes:

[0077] The system detects whether there is a boiler trigger signal. If so, the control device controls the electrode boiler 9 to work according to the boiler trigger signal to provide heat to the heat source output terminal.

[0078] In this embodiment of the invention, the boiler trigger signal can be sent by an external device electrically connected to the control device. For example, in extreme weather conditions with very low temperatures, information transmitted through a temperature sensing device or other electronic device can be used. After receiving the information, the control device controls the electrode boiler 9 to operate as a backup device for providing heat sources, so as to provide more heat to the user end and meet the user's heat load requirements. This optimizes the operating performance of the system.

[0079] This invention discloses a control device applied to an integrated energy system, the control device comprising:

[0080] The operating model determination module is used to determine the operating model of the system based on time, and the operating model includes a first mode, a second mode, and a third mode.

[0081] The energy control operation module is used to perform energy control operations according to the operation model within the time period corresponding to the power level; the power time period includes: power off-peak period, power peak period and power peak period.

[0082] The energy control operation module includes:

[0083] The first mode execution unit is configured to, according to the first mode, provide cooling capacity from the centrifugal chiller 3 to the plate heat exchanger 6 and the cold source output terminal during periods of low electricity demand, and to store cold energy in the energy storage tank 4; during periods of high electricity demand, the energy storage tank 4 provides cooling capacity from the plate heat exchanger 6 and the centrifugal chiller 3 to the cold source output terminal; and during periods of peak electricity demand, the energy storage tank 4 provides cooling capacity from the plate heat exchanger 6 and the cold source output terminal.

[0084] The second mode execution unit is configured to, according to the second mode, provide heat to the heat source output terminal of the heat pump unit 2 during the off-peak period and store heat in the energy storage tank 4; provide heat to the heat source output terminal of the heat pump unit 2 during the peak period and stop storing heat in the energy storage tank 4; and provide heat to the heat source output terminal of the energy storage tank 4 during the peak period; wherein, the sewage tank 1 provides cooling capacity to the plate heat exchanger 6.

[0085] The third mode execution unit is used to, according to the third mode, store cold in the energy storage tank 4 during the off-peak period, and provide cooling to the energy storage tank 4 and the plate heat exchanger 6 by the centrifugal chiller unit 3. During the peak and high-peak periods, the energy storage tank 4 and the sewage tank 1 provide cooling to the plate heat exchanger 6.

[0086] In an optional embodiment of the invention, the control device may further include:

[0087] The maintenance module is used to detect whether the sewage tank 1 meets the preset maintenance conditions. If it does, it controls the water in the water replenishment tank 7 to be discharged to replenish the circulating water to the system.

[0088] In an optional embodiment of the invention, the control device may further include:

[0089] The boiler trigger module is used to detect whether there is a boiler trigger signal. If there is, it controls the electrode boiler 9 to work according to the boiler trigger signal to provide heat to the heat source output terminal.

[0090] In summary, by using wastewater energy as the system input source and employing integrated collaboration with heat pump unit 2, centrifugal chiller unit 3, and plate heat exchanger 6, the system can provide users or data center IT equipment with various energy needs, including cooling and heating, ensuring the safe and stable operation of the data center. Furthermore, it can recover and reuse the heat generated by the data center, preventing the conversion of large amounts of electrical energy consumption into heat dissipation that exacerbates the greenhouse effect. Different equipment operation models are set according to different seasons, and the operation of relevant equipment in the system is controlled in different time periods under the same operation model. Peak shaving and valley filling are achieved through energy storage tank 4, thereby achieving energy saving and reducing system operating costs. Simultaneously, the energy station and data center share energy supply equipment, realizing multi-energy coordinated supply and comprehensive cascade utilization of energy in urban areas.
