[0054] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] The main solutions of the embodiments of this application are:

[0057] At present, the cross-industry recycling system of water heat / cold energy lacks an energy complementary mechanism with urban infrastructure, and the waste heat of data centers cannot be recycled, resulting in low energy utilization efficiency.

[0058] The present application absorbs the heat generated by the server cabinets in the data center through the liquid cooling heat exchange system of the data center, realizes the effective recovery of the waste heat of the data center, transfers the high-temperature return water generated by the liquid cooling heat exchange system of the data center to the comprehensive heat exchange system, and transfers it to the high-temperature heat pump system through the comprehensive heat exchange system.

The present application realizes the technical effect of recycling the excess heat generated by the data center.

[0059] It should be noted that the execution subject of this embodiment can be a water heat / cold energy cross-industry recycling system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a control device of a water heat / cold energy cross-industry recycling system that can realize the above functions, etc. This embodiment does not specifically limit this. The following takes the water heat / cold energy cross-industry recycling system as an example of the execution subject to illustrate this embodiment and the following embodiments.

[0060] Embodiment 1

[0061] Based on this, the present application proposes a water heat / cold energy cross-industry recycling system of the first embodiment, please refer to Figure 1 and Figure 2 The water heat / cold energy cross-industry recycling system includes a data center liquid cooling heat exchange system 10, a comprehensive heat exchange system 20 and a high-temperature heat pump system 30.

[0062] In this embodiment, the data center liquid cooling heat exchange system 10 is used to receive low-temperature return water from the integrated heat exchange system 20 to perform heat exchange of server cabinets, and transmit high-temperature return water generated by the heat exchange to the integrated heat exchange system 20 .

[0063] A large amount of heat is generated during the operation of the data center. The heat is absorbed by the coolant to ensure that the computer equipment operates within a suitable temperature range, thereby improving the stability and reliability of the equipment. At the same time, the heat of the coolant is transferred to the heat storage tank 21 of the comprehensive heat exchange system 20, which can provide a heat source for the high-temperature heat pump system 30, realize the recycling of energy, and improve energy utilization efficiency.

[0064] It should be noted that the data center liquid cooling heat exchange system 10 is a system that uses liquid cooling medium to absorb and remove heat generated by the server cabinet. The data center liquid cooling heat exchange system 10 transfers the heat of the server cabinet to the cooling medium through a heat exchange process, so that the server cabinet maintains a suitable operating temperature.

[0065] As an optional implementation, sensors are used to monitor the temperature parameters of the server cabinet. Through the cold plate liquid cooling system, the coolant is circulated through the cold plate, directly contacting the heat-generating components of the server cabinet to absorb heat. The coolant is then drawn out of the cold plate and enters the heat storage tank 21 of the integrated heat exchange system 20.

[0066] Optionally, sensors are used to monitor the temperature parameters of the server cabinet, and through an immersion liquid cooling system, the heat of the heat-generating components of the server cabinet immersed in the cooling liquid is absorbed by the cooling liquid and transferred to the heat storage tank 21 of the integrated heat exchange system 20.

[0067] Optionally, sensors are used to monitor the temperature parameters of the server cabinet, and the coolant is evenly sprayed on the heat-generating components of the server cabinet through a spray liquid cooling system to absorb heat and transfer it to the heat storage tank 21 of the integrated heat exchange system 20.

[0068] As an optional implementation, a liquid cooling heat exchange unit is installed inside or near the server cabinet, and the cooling medium is circulated to the heat exchange unit through a pipeline to perform heat exchange with the heat source in the server cabinet. After the heat exchange, the cooling medium becomes high-temperature return water and is transported back to the integrated heat exchange system 20 through a pipeline.

[0069] Furthermore, the data center liquid cooling heat exchange system 10 includes a cold plate liquid cooling data center 11 , an internal circulation system 12 , a cooling distribution unit 13 and an external circulation system 14 .

[0070] In this embodiment, the cold plate liquid cooling data center 11 is used to receive the cooling liquid of the internal circulation system 12 to perform heat exchange of the server cabinet and transfer the heat generated by the heat exchange to the internal circulation system 12 .

[0071] It should be noted that the cold plate liquid cooling data center 11 is a data center that adopts cold plate liquid cooling technology, and absorbs and takes away the heat generated by the server cabinets through the circulation of cooling liquid in the cold plate.

[0072] Optionally, cold plates are mounted directly on server components for efficient heat exchange.

[0073] As an optional implementation, a cold plate liquid cooling unit is installed in the server cabinet, and each server component is equipped with a corresponding cold plate. The coolant circulates in the cold plate through pipes, absorbs the heat generated by the server components, and returns to the internal circulation system 12 through pipes.

[0074] For example, a server cabinet using cold plate liquid cooling technology has a single cabinet power of 30 kilowatts, 250 cabinets, and a total computer equipment power consumption of 7.5 megawatts. The cold plate directly contacts the high-heat components of the computer equipment in the server cabinet, taking away the heat generated by the equipment operation, with a heat exchange efficiency of up to 95%.

[0075] Furthermore, the internal circulation system 12 is used to transfer the internal circulation coolant of the internal circulation system 12 to the cold plate liquid cooling data center 11, receive the heat generated by the heat exchange of the server cabinet through the internal circulation coolant, and transfer the heat of the internal circulation coolant to the cooling distribution unit.

[0076] It should be noted that the internal circulation system 12 is a closed heat management system for circulating coolant inside the cold plate liquid cooling data center 11, receiving and transferring heat generated by heat exchange of the server cabinets. The internal circulation system 12 includes components such as a coolant pump, an internal circulation pipeline, and a liquid storage tank.

[0077] The heat generated by the server cabinet is directly absorbed by the internal circulation coolant, and then the heat is transferred to the external circulation coolant through the heat exchanger, which can prevent the high-temperature internal circulation coolant from directly contacting the external environment or other parts of the equipment, thereby protecting the equipment and improving the heat dissipation efficiency. At the same time, the external circulation coolant, as a heat transfer medium, can take the heat away from the server cabinet area to prepare for further heat dissipation.

[0078] Internal circulation coolant is a coolant used to circulate inside the server cabinet, directly contacting the heat-generating components through the cold plate, and used to absorb the heat of the heat-generating components of the server cabinet. The cold plate is a high-efficiency heat exchanger installed on the heat-generating components of the server cabinet, and is designed with a coolant channel inside to transfer the heat generated by the heat-generating components to the coolant flowing through. External circulation coolant is a coolant that does not directly contact the server cabinet, but carries heat through heat exchange with the internal circulation coolant. A heat exchanger is a device used to transfer heat between two or more fluids without mixing them.

[0079] Furthermore, the data center liquid cooling heat exchange system 10 also includes an internal circulation pipeline and an external circulation pipeline.

[0080] In this embodiment, the internal circulation pipeline is used to connect the cooling distribution unit 13 and the cold plate type liquid cooling data center 11 to form a closed loop.

[0081] It should be noted that the inner circulation pipeline is installed in the inner circulation system 12 as a supplementary part of the inner circulation system, and the outer circulation pipeline is installed in the outer circulation system 14 as a supplementary part of the outer circulation system.

[0082] As an optional implementation, a coolant pump is installed in the internal circulation system 12 to drive the coolant through the internal circulation pipeline to circulate between the cold plate type liquid cooling data center 11 and the cooling distribution unit 13.

[0083] Exemplarily, the cooling liquid of the internal circulation system 12 has a temperature range of 41 degrees Celsius to 51 degrees Celsius, and circulates inside the data center to remove heat from computer equipment in server cabinets.

[0084] For example, the cold plate is precisely installed according to the internal layout of the server cabinet and the location of the heat generating components, and is connected to the internal circulation coolant circulation pump through the pipeline system, and the internal circulation coolant circulation pump is started to form a closed loop between the cold plate and the circulation pump. When the coolant flows in the cold plate, it absorbs the heat generated by the heat generating components. When the temperature of the internal circulation coolant rises, it exchanges heat with the external circulation coolant through the heat exchanger.

[0085] Furthermore, the external circulation system 14 is used to receive low-temperature return water from the integrated heat exchange system 20, use the low-temperature return water as the external circulation coolant, receive the heat transferred by the cooling distribution unit 13 through the external circulation coolant, and transfer it to the integrated heat exchange system 20 as high-temperature return water.

[0086] The heat is carried by the external circulating coolant and transferred to the heat storage tank 21, so as to realize the final discharge of the heat. The heat storage tank 21 serves as a heat storage and discharge unit, which can ensure that the heat is safely and effectively removed to avoid the accumulation of heat in the data center.

[0087] In this embodiment, the external circulation pipeline is used to connect the cooling distribution unit 13 and the integrated heat exchange system 20 .

[0088] It should be noted that the external circulation system 14 is a thermal energy management system connected to the integrated heat exchange system 20. The external circulation system 14 receives the heat transferred by the cooling distribution unit 13, and transfers the heat to the integrated heat exchange system 20 through the external circulation coolant.

[0089] As an optional implementation, a pump and an external circulation pipeline are installed in the external circulation system 14 to drive the external circulation coolant to circulate between the cooling distribution unit 13 and the integrated heat exchange system 20 .

[0090] Optionally, valves and sensors are provided to monitor and control the temperature and flow rate of the externally circulating coolant.

[0091] Exemplarily, the coolant temperature of the external circulation system 14 ranges from 36 degrees Celsius to 46 degrees Celsius, and after heat exchange with the internal circulation system 12 , the heat is transferred to the integrated heat exchange system 20 .

[0092] Furthermore, the cooling distribution unit 13 is used to manage the internal circulation system 12 and the external circulation system 14 , receive the heat of the internal circulation coolant, and transfer the heat of the internal circulation coolant to the external circulation coolant of the external circulation system 14 .

[0093] It should be noted that the cooling distribution unit 13 is a heat energy distribution device for managing the heat energy transfer between the internal circulation system 12 and the external circulation system 14. The cooling distribution unit 13 receives the heat of the internal circulation coolant and distributes it to the coolant of the external circulation system 14 to achieve the reuse and distribution of heat energy.

[0094] As an optional implementation, the cooling distribution unit 13 is responsible for the separation and heat exchange of the internal circulation system 12 and the external circulation system 14 .

[0095] Optionally, the cooling distribution unit 13 includes a heat exchanger and a control system. The heat exchanger is used to achieve heat energy transfer between the inner circulating coolant and the outer circulating coolant. The control system is used to monitor and control the heat exchange process to ensure the reasonable distribution and transfer of heat energy.

[0096] Exemplarily, the heat exchanger of the cooling distribution unit 13 is started to receive the heat of the inner circulation coolant and distribute it to the coolant of the outer circulation system 14, and the heat exchange process is monitored and controlled to ensure the reasonable distribution and transfer of heat energy.

[0097] In this embodiment, the integrated heat exchange system 20 is used to receive high-temperature return water from the data center liquid cooling heat exchange system 10, transfer the high-temperature return water to the high-temperature heat pump system 30, and receive low-temperature return water from the high-temperature heat pump system 30, and transfer the low-temperature return water to the data center liquid cooling heat exchange system 10.

[0098] It should be noted that the comprehensive heat exchange system 20 includes a heat storage tank 21 , a reflux water tank 22 , a circulating water pump 24 and a liquid level control system 23 .

[0099] Furthermore, the heat storage tank 21 is used to receive and store high-temperature return water of the data center liquid cooling heat exchange system 10, and transfer the high-temperature return water to the high-temperature heat pump system 30, receive low-temperature return water from the return water tank 22, and transfer the low-temperature return water to the data center liquid cooling heat exchange system 10.

[0100] It should be noted that the heat storage tank 21 is a container for storing and transferring heat. The heat storage tank 21 is used to receive and store the high-temperature return water generated by the data center liquid cooling heat exchange system 10, and the high-temperature return water contains the heat energy generated by the data center equipment. At the same time, the heat storage tank 21 also receives the low-temperature return water from the return water tank 22, and prepares to transfer the low-temperature return water to the data center liquid cooling heat exchange system 10 again for cooling circulation.

[0101] Optionally, a temperature sensor and a liquid level sensor are provided inside the heat storage tank to monitor water quality and liquid level changes in real time.

[0102] As an optional implementation, the heat storage tank 21 is designed as a container with sufficient capacity and good thermal insulation performance to ensure that the stored heat is not lost too quickly.

[0103] Exemplarily, the heat storage tank 21 stores high-temperature return water from the external circulation system 14, and the water temperature is about 40-50 degrees Celsius. The capacity of the heat storage tank 21 is about 1800-2200 cubic meters, which is used to adjust the supply and demand of heat energy and ensure the stability of the heat source of the high-temperature heat pump.

[0104] Furthermore, the return water tank 22 is used to receive low-temperature return water from the high-temperature heat pump system 30 , and transfer the low-temperature return water to the heat storage tank 21 through the circulating water pump 24 .

[0105] As an optional embodiment, the return water pool 22 is designed as a container with sufficient capacity and good thermal insulation performance.

[0106] Optionally, a liquid level sensor is provided inside the reflux pool 22 to monitor the liquid level change in real time, and is connected to the liquid level control system 23 to ensure the stability of the water level.

[0107] It should be noted that the return water tank 22 is used to receive low-temperature return water after being processed by the high-temperature heat pump system 30, and transfer the low-temperature return water to the heat storage tank 21 again through the circulating water pump 24, thereby forming a closed water cycle.

[0108] Exemplarily, the return water pool 22 stores low-temperature return water after the high-temperature heat pump extracts heat, and the water temperature is about 36 degrees Celsius. It receives high-temperature water generated by the high-temperature heat pump system 30 to maintain the water balance of the system.

[0109] Optionally, the return water pool 22 receives high-temperature water generated by the high-temperature heat pump cold end of the high-temperature heat pump system 30, the grey water supply system, and the air-conditioning heat pump of the air-conditioning system.

[0110] Furthermore, the liquid level control system 23 is used to monitor the liquid levels of the heat storage tank 21 and the return water tank 22, and adjust the circulating water pump 24 according to the changes in the liquid levels.

[0111] It should be noted that the liquid level control system 23 adjusts the working state of the circulating water pump 24 according to the changes in the liquid levels of the heat storage tank 21 and the return water tank 22 to maintain the liquid level of the system stable. The liquid level control system 23 is composed of a liquid level sensor and a controller.

[0112] Furthermore, the circulating water pump 24 is used to maintain water circulation in the heat storage tank 21 and the return water tank 22 .

[0113] It should be noted that the circulating water pump 24 is a power source for driving water to circulate between the heat storage tank 21 and the return water tank 22. The circulating water pump 24 adjusts the speed or on / off state of the water pump according to the instructions of the liquid level control system 23 to maintain the water circulation and liquid level stability of the system.

[0114] Optionally, the circulating water pump 24 uses a high-efficiency and energy-saving variable frequency water pump, and the rotation speed of the water pump is automatically adjusted according to the signal of the liquid level control system 23.

[0115] Optionally, valves and filters are provided at the inlet and outlet of the circulating water pump 24 to control the water flow and protect the water pump.

[0116] For example, the circulating water pump 24 is set to a high standby ratio of "1:1" to ensure reliable operation of the system. The circulating water pump 24 maintains water circulation between the heat storage tank 21 and the return water tank 22, and the flow rate can reach 550-650 cubic meters per hour.

[0117] As an optional implementation, liquid level sensors are installed at appropriate locations of the heat storage tank 21 and the return water tank 22, and transmit real-time monitored liquid level signals to the controller. The controller issues instructions to the circulating water pump 24 to adjust the working state of the water pump based on the preset liquid level range and control strategy.

[0118] Optionally, the liquid level control system 23 is designed as an automatic control system based on a PLC (Programmable Logic Controller) or a DCS (Distributed Control System).

[0119] Exemplarily, the liquid level control system 23 monitors the liquid levels of the heat storage tank 21 and the return water tank 22 in real time through sensors, and automatically adjusts the operation of the circulating water pump 24 according to the changes in the liquid levels to ensure that the liquid levels are within a safe range.

[0120] Optionally, the integrated heat exchange system 20 further includes a grey water replenishment system. When the liquid level of the return water tank 22 is detected by the liquid level control system 23 to be lower than a preset minimum liquid level, if the liquid level of the heat storage tank 21 is also lower than the preset minimum liquid level, a control signal is sent to the grey water replenishment system to replenish grey water into the return water tank 22.

[0121] It should be noted that reclaimed water is recycled water that has been treated to a certain water quality standard but has not yet reached the drinking water standard and is used as a water replenishment source for the integrated heat exchange system. Reclaiming with reclaimed water can effectively utilize water resources, reduce dependence on traditional water resources, and reduce production costs.

[0122] As an optional implementation, reclaimed water is obtained as a water replenishment source for the system. When the system is short of heat or water, water is replenished to the return water tank 22 in time to maintain the normal operation of the system.

[0123] For example, when the water heat / cold energy cross-industry recycling system is applied to a sewage treatment plant to perform heat circulation between a data center and the sewage treatment plant, the reclaimed water from the sewage treatment plant is used as the water replenishment source for the system.

[0124] In this embodiment, the high-temperature heat pump system 30 is used to receive the high-temperature return water of the integrated heat exchange system 20 to perform heat release treatment to generate the low-temperature return water, and transfer the low-temperature return water to the integrated heat exchange system 20 .

[0125] It should be noted that the high-temperature heat pump system 30 is a system that absorbs heat from a low-temperature heat source and upgrades it to high-temperature thermal energy.

[0126] Furthermore, the high-temperature heat pump system 30 includes a high-temperature water source heat pump unit 31 , a heat release device 33 , and a hot water supply and recovery system 32 .

[0127] In this embodiment, the high-temperature water source heat pump unit 31 is used to receive high-temperature return water from the integrated heat exchange system 20 as a heat source, increase the temperature of the low-temperature hot water in the high-temperature water source heat pump unit 31, and transfer the high-temperature hot water to the hot water supply and recovery system 32 as high-temperature hot water, and transfer the high-temperature return water to the integrated heat exchange system 20 as low-temperature return water after taking heat.

[0128] It should be noted that the high-temperature water source heat pump unit 31 is a device that utilizes low-temperature heat sources such as geothermal heat and industrial waste heat and converts them into high-temperature thermal energy through heat pump technology. The high-temperature water source heat pump unit 31 is mainly composed of a compressor, an evaporator, a condenser, and a throttling device, etc., and realizes the transfer and improvement of thermal energy through the phase change process of the circulating working fluid in the system.

[0129] Optionally, the low-pressure and low-temperature refrigerant vapor is compressed into high-pressure hot steam and transported to the condenser through the compressor of the high-temperature water source heat pump unit 31. The high-pressure hot steam releases heat in the condenser to heat the water source in the heat storage tank to the required high temperature. The high-temperature water source heated by the high-temperature water source heat pump unit 31 is transported to the heat release equipment 33 through the pipeline transportation system, and the low-temperature water source generated by the heat release in the heat release equipment 33 is transported back to the reflux water tank 22 through the pipeline system.

[0130] As an optional embodiment, the high-temperature water source heat pump unit 31 receives high-temperature return water from the integrated heat exchange system 20 as a heat source. The compressor in the unit compresses the circulating working fluid to increase its temperature and pressure, and then the working fluid releases heat in the condenser to heat the low-temperature hot water into high-temperature hot water. The high-temperature hot water is then transferred to the hot water supply and recovery system 32, and the low-temperature return water after heat release returns to the integrated heat exchange system 20 to continue to absorb heat.

[0131] For example, the 46-degree Celsius high-temperature water in the heat storage tank 21 of the integrated heat exchange system 20 is used as a heat source, and the water temperature is raised to 70-90 degrees Celsius through heat pump technology. The heating capacity of each high-temperature water source heat pump unit 31 is 0.6-0.8 megawatts, and 4-6 high-temperature water source heat pump units 31 are used to meet the heat demand of the subsequent heat release equipment 33.

[0132] In this embodiment, the hot water supply and recovery system 32 is used to receive the high-temperature hot water from the high-temperature water source heat pump unit 31, transfer the high-temperature hot water to the heat release device 33, and receive the low-temperature hot water generated by the heat release device 33, and transfer the low-temperature hot water to the high-temperature water source heat pump unit 31.

[0133] It should be noted that the hot water supply and recovery system 32 is a system for receiving, distributing and recovering high-temperature hot water and low-temperature hot water between the high-temperature water source heat pump unit 31 and the heat release equipment 33, ensuring the effective transfer and recovery of heat energy within the system.

[0134] As an optional implementation, the hot water supply and recovery system 32 first receives the high-temperature hot water from the high-temperature water source heat pump unit 31, and then distributes it to the heat release device 33 for heating. At the same time, the system is also responsible for receiving the low-temperature hot water generated by the heat release device 33, recovering it and transferring it to the high-temperature water source heat pump unit 31 for reheating. This process forms a closed cycle, realizing the efficient utilization and recovery of thermal energy.

[0135] Exemplarily, the 80-degree high-temperature hot water generated by the high-temperature water source heat pump unit 31 is supplied to the heat release device 33. After releasing the heat, the temperature drops to 65-75 degrees Celsius. The generated 65-75-degree low-temperature hot water flows back to the high-temperature water source heat pump unit 31, forming a closed cycle.

[0136] In this embodiment, the heat release device 33 is used to receive high-temperature hot water from the hot water supply and recovery system 32 , use the high-temperature hot water for heat release treatment, and transfer the low-temperature hot water generated after heat release to the hot water supply and recovery system 32 .

[0137] It should be noted that the heat release device 33 refers to a device that uses high-temperature hot water for heating or heat release, such as a heating system, hot water bathing facilities, industrial heaters, etc. The heat release device 33 receives the high-temperature hot water provided by the hot water supply and recovery system 32, and uses the heat energy therein for heating treatment.

[0138] As an optional embodiment, the heat release device 33 receives high-temperature hot water from the hot water supply and recovery system 32, and uses the heat energy in the hot water for heating, bathing or industrial heating. After heat release, the low-temperature hot water returns to the hot water supply and recovery system 32, and is then transferred by the system to the high-temperature water source heat pump unit 31 for reheating.

[0139] Optionally, in a sewage treatment plant, the heat release device 33 is a sludge drying device, which uses high-temperature hot water to dry the sludge and reduce the moisture content to less than 40%. The temperature of the water source is increased by the high-temperature water source heat pump unit 31, and the water source after the temperature increase is transported to the sludge drying equipment of the sewage treatment plant to achieve efficient sludge drying. The use of the high-temperature water source heat pump unit 31 to provide heat energy can significantly improve the efficiency of sludge drying, which not only improves the energy utilization efficiency, reduces the energy consumption and operating costs of the data center, but also provides a clean and low-cost heat energy source for the sewage treatment plant.

[0140] The present embodiment provides a cross-industry recycling system for water heat / cold energy. The present embodiment absorbs the heat generated by the server cabinets in the data center through the data center liquid cooling heat exchange system 10, thereby realizing effective recovery of waste heat in the data center. The high-temperature return water generated by the data center liquid cooling heat exchange system 10 is transferred to the integrated heat exchange system 20, and then transferred to the high-temperature heat pump system 30 through the integrated heat exchange system 20. The high-temperature heat pump system 30 extracts the heat energy in the high-temperature return water provided by the integrated heat exchange system 20 through heat release treatment, and upgrades it to heat energy at a higher temperature. The treated low-temperature return water is returned to the integrated heat exchange system 20, and then transferred to the data center liquid cooling heat exchange system 10, thereby realizing the recycling and balance of heat energy.

[0141] Based on the first embodiment, the second embodiment of the present application proposes a water heat / cold energy cross-industry recycling system, referring to Figure 3 The water heat / cold energy cross-industry recycling system also includes an air conditioning system 40:

[0142] In this embodiment, the air conditioning system 40 is used to process the ambient heat of the data center and transfer the heat generated by the operation of the low-temperature heat pump to the integrated heat exchange system 20 .

[0143] The air conditioning system 40 effectively processes the ambient heat generated by the data center, and transfers the heat to the integrated heat exchange system 20 through the operation of the low-temperature heat pump unit 43, thereby realizing effective circulation and utilization of heat energy. This can not only reduce the energy consumption of the data center, improve energy utilization efficiency, but also reduce the impact on the environment.

[0144] It should be noted that the air conditioning system 40 is a system for adjusting the internal ambient temperature of the data center. A series of devices are used to keep the internal ambient conditions of the data center within an appropriate range to ensure the normal operation of the data center equipment and extend its service life.

[0145] Ambient heat is a large amount of heat generated during the operation of the data center. It is the heat that is not completely absorbed by the data center liquid cooling heat exchange system 10. This heat comes from the operation of various electronic devices such as servers, storage devices, and network devices. If the ambient heat is not handled in time, it will cause the temperature inside the data center to be too high, affecting the performance and stability of the equipment.

[0146] A low temperature heat pump is a device that absorbs heat from a low temperature heat source and converts it into high temperature heat energy through compression and condensation processes. The air conditioning system 40 controls the low temperature heat pump to utilize the ambient heat generated by the data center as a low temperature heat source and generate high temperature heat energy through operation.

[0147] In this embodiment, the air conditioning system 40 includes an inter-row air conditioner 41 , a cold storage water tank 42 and a low-temperature heat pump unit 43 .

[0148] Furthermore, the inter-row air conditioner 41 is used to receive low-temperature cooling water from the cold storage water tank 42 to process the ambient heat of the data center, generate heated cooling water, and transfer the heated cooling water to the cold storage water tank 42 .

[0149] It should be noted that the inter-row air conditioner 41 is an air conditioning device installed between the server cabinets in the data center, which directly cools the equipment in the server cabinets and effectively handles the ambient heat generated by the data center. The inter-row air conditioner 41 has the characteristics of small size, high cooling efficiency and low noise.

[0150] As an optional implementation, the inter-row air conditioner 41 receives low-temperature cooling water from the cold water storage tank 42 through a pipeline system, and uses the cooling water to cool the equipment in the data center server cabinet. As heat is exchanged, the temperature of the cooling water gradually increases, forming heated cooling water. The inter-row air conditioner 41 returns the heated cooling water to the cold water storage tank 42 through a pipeline system.

[0151] Exemplarily, the inter-row air conditioner 41 is responsible for controlling the ambient temperature of the data center, processing 5% of the heat not removed by the data center liquid cooling heat exchange system 10 and the ambient heat load, using cooling water from the cold storage water tank 42 for cooling, and ensuring that the temperature of the computer room is stable at around 15-25 degrees Celsius.

[0152] Optionally, temperature sensors are installed at key locations inside the data center to monitor the ambient temperature in real time.

[0153] Optionally, upper and lower temperature thresholds are set according to the heat dissipation performance of the data center equipment and preset temperature requirements.

[0154] Exemplarily, when the ambient temperature exceeds a preset upper threshold, an instruction is sent to the inter-row air conditioner 41 to increase the cooling power of the inter-row air conditioner 41 or to turn on additional air conditioning equipment. When the ambient temperature is lower than a preset lower threshold, an instruction is sent to the inter-row air conditioner 41 to reduce the cooling power of the inter-row air conditioner 41 or to turn off some air conditioning equipment.

[0155] In this embodiment, the cold storage water tank 42 is used to receive the heated cooling water generated by the inter-row air conditioner 41 to increase the temperature of the cooling water in the cold storage water tank 42 .

[0156] It should be noted that the cold storage water tank 42 is a container for storing cooling water, and contains low-temperature cooling water. The cold storage water tank 42 receives the heated cooling water generated by the inter-row air conditioner 41 and provides a stable water source for the low-temperature heat pump unit 43, thereby realizing the recycling of cooling water.

[0157] As an optional embodiment, the cold storage water tank 42 receives the heated cooling water from the inter-row air conditioner 41 and stores it inside. As the heated cooling water is continuously added, the temperature of the cooling water in the cold storage water tank 42 gradually increases. When the temperature of the cooling water in the cold storage water tank 42 reaches a certain level, the low-temperature heat pump unit 43 starts to work.

[0158] For example, the cold storage water tank 42 stores low-temperature cooling water with a capacity of about 450-550 cubic meters. When the water temperature is low, it is directly supplied to the inter-row air conditioner 41; when the water temperature rises, it is cooled by the low-temperature heat pump unit 43.

[0159] Optionally, one or more temperature sensors are installed inside or near the cold storage water tank 42 to monitor the source temperature of the cooling water in real time.

[0160] Optionally, a temperature threshold of the cooling water source is set according to the heat dissipation demand of the data center and the performance of the cooling system.

[0161] Furthermore, the source temperature of the cooling water in the cold water storage tank 42 of the data center is monitored to ensure that the cooling water can effectively absorb the ambient heat generated by the data center and maintain it within an appropriate temperature range to ensure the normal operation and efficient heat dissipation of the data center. A large number of computer devices in the data center will generate a large amount of heat during operation. If this heat cannot be dissipated in time, it will cause the equipment to overheat, affect performance and stability, and may even cause equipment damage. Therefore, by monitoring the source temperature of the cooling water in the cold water storage tank 42, the operating state of the cooling system can be adjusted in time to ensure that the ambient temperature of the data center is controlled within a safe and stable range.

[0162] In this embodiment, the low-temperature heat pump unit 43 is used to reduce the temperature of the cooling water in the cold storage water tank 42 and transfer the generated heat to the integrated heat exchange system 20 .

[0163] It should be noted that the low-temperature heat pump unit 43 is a device that can absorb heat from a low-temperature heat source and convert it into high-temperature heat energy through compression and condensation processes. In the data center, the low-temperature heat pump unit 43 uses the heated cooling water in the cold storage water tank 42 as a low-temperature heat source, generates high-temperature heat energy through operation, and transmits it to the integrated heat exchange system 20.

[0164] As an optional implementation, the low-temperature heat pump unit 43 extracts the heated cooling water from the cold storage water tank 42, reduces its temperature through compression and condensation processes, and recovers and generates high-temperature heat energy, which is transferred to the integrated heat exchange system 20 through the pipeline system. The cooling water treated by the low-temperature heat pump unit 43 returns to the cold storage water tank 42 again, waiting for the next cycle.

[0165] For example, when the water temperature of the cold storage water tank 42 is higher than the set value, the low temperature heat pump unit 43 is started to reduce the water temperature. The heat generated during the operation of the heat pump is recovered and enters the return water tank 22, thereby improving the utilization efficiency of heat energy.

[0166] When it is detected that the cooling water temperature in the cold storage water tank 42 is higher than the preset temperature threshold, active measures are taken to reduce the cooling water temperature to ensure continuous and effective cooling services for the data center. When the cooling water temperature is too high, the ability to absorb heat will decrease, thereby affecting the heat dissipation effect of the data center. Through the low-temperature heat pump unit 43, the heat in the cooling water can be effectively transferred to the return water pool 22 of the integrated heat exchange system 20, thereby reducing the cooling water temperature and maintaining the stability and efficiency of the cooling system.

[0167] Optionally, a temperature sensor is installed in the cold storage water tank 42 to monitor the cooling water temperature in real time.

[0168] Optionally, the heat pump heat generated by the operation of the low-temperature heat pump unit 43 is transferred to the return water pool 22 to improve energy utilization efficiency and achieve heat recovery and reuse. The low-temperature heat pump unit 43 absorbs heat from the cooling water, and through the circulation and compression process of the working medium, the heat is raised to a higher temperature level and transferred to the return water pool to heat the water in the pool.

[0169] Exemplarily, if the cooling water temperature is higher than a preset threshold, the start signal of the low-temperature heat pump unit 43 is triggered, and the low-temperature heat pump unit 43 circulates to absorb heat from the cold water tank 42 and transfer it to the return water pool 22, and the cooling water temperature in the cold water tank 42 gradually decreases.

[0170] The present embodiment provides a cross-industry recycling system for water heat / cold energy. The present embodiment firstly efficiently processes the ambient heat generated by the equipment in the rack through the inter-row air conditioner 41 in the air-conditioning system 40 to maintain the stability of the internal environment of the data center. The heat is recovered from the heated cooling water in the cold storage water tank 42 through the low-temperature heat pump unit 43, converted into high-temperature thermal energy, and transmitted to the integrated heat exchange system 20, thereby improving the energy utilization efficiency of the data center.

[0171] Based on Example 1, Example 3 of the present application proposes a control method for a water heat / cold energy cross-industry recycling system, referring to Figure 4 The control method of the water heat / cold energy cross-industry recycling system includes:

[0172] Step S10, monitoring the temperature of the server cabinet in the liquid cooling heat exchange system of the data center and the parameters of the heat release equipment in the high-temperature heat pump system, wherein the changes in the parameters reflect the heat energy demand of the heat release equipment.

[0173] By acquiring the temperature information of the server cabinet in real time, potential overheating problems can be discovered and handled in a timely manner to prevent the server from performance degradation or damage due to excessive temperature. At the same time, monitoring the parameter changes of the heat release equipment can reflect its thermal energy demand, thereby adjusting the working state of the high-temperature heat pump system, realizing the reasonable distribution and utilization of thermal energy, and improving the energy efficiency of the water heat / cold energy cross-industry recycling system.

[0174] Optionally, a temperature sensor is installed inside the server cabinet to monitor the temperature inside the cabinet in real time.

[0175] Optionally, monitoring instruments such as temperature sensors and flow meters are installed at the inlet and outlet of the heat release equipment to monitor the temperature, flow rate and other parameters of the heat release equipment in real time.

[0176] For example, if an increase in the outlet temperature parameter of the heat release device is monitored, the heat release device is releasing too much heat, reflecting a decrease in thermal energy demand; if a decrease in the outlet temperature parameter of the heat release device is monitored, the heat release device needs to release more heat to reach the set temperature, reflecting an increase in thermal energy demand.

[0177] For example, when the inlet and outlet flow rates of the heat release device increase, more fluid needs to be heated or cooled, reflecting an increase in thermal energy demand; when the inlet and outlet flow rates of the heat release device decrease, reflecting a decrease in thermal energy demand.

[0178] As an optional implementation, a temperature sensor is used to monitor the temperature inside the server cabinet in real time and transmit the data to the control system. The parameters of the heat release equipment in the high-temperature heat pump system are monitored by sensors and the data are transmitted to the control system.

[0179] Step S20: if the temperature of the server cabinet exceeds a preset temperature threshold, the operating power of the high-temperature water source heat pump unit in the high-temperature heat pump system is increased to recover excess heat.

[0180] When the temperature of the server cabinet exceeds the preset temperature threshold, the operating power of the high-temperature water source heat pump unit in the high-temperature heat pump system is increased to timely and effectively recover the excess heat generated in the server cabinet and convert it into usable thermal energy resources to achieve energy recycling.

[0181] In this embodiment, the server cabinet is an equipment cabinet in a data center for installing servers. The preset temperature threshold is the maximum allowable temperature value set to ensure the normal operation of the server. When the temperature exceeds the preset temperature threshold, measures need to be taken to reduce the temperature.

[0182] As an optional implementation, when the temperature exceeds a preset temperature threshold, the operating power of the high-temperature water source heat pump unit is automatically adjusted. By increasing the operating power of the unit, the ability to absorb heat from the server cabinet is improved, thereby accelerating the cooling speed.

[0183] Optionally, the high-temperature water source heat pump unit transfers the absorbed heat to a high-temperature heat source, including a hot water storage tank or a steam generator; the hot water or steam can be used in other systems in the data center, including heating, humidification, cleaning, etc., to achieve the recycling of thermal energy.

[0184] Step S30: if the heat energy demand of the heat release equipment increases, the operating power of the high-temperature water source heat pump unit is increased to increase the heat energy output.

[0185] By increasing the operating power of the unit, the heat output of the high-temperature water source heat pump system can be increased, thereby meeting the high demand for heat energy from heat-releasing equipment, maintaining a stable temperature in data centers or other areas with high heat demand, and improving the energy efficiency and reliability of the overall system.

[0186] In this embodiment, the heat energy demand is the heat energy required by the heat-releasing device to maintain or reach a specific temperature or working state. The heat energy demand varies due to factors such as environmental conditions, device load, and working time.

[0187] As an optional implementation, when it is monitored that the heat energy demand of the heat release equipment increases, the operating power of the high-temperature water source heat pump unit is automatically adjusted through the control system.

[0188] Optionally, variable frequency speed regulation technology is used to smoothly adjust the speed and power output of the unit according to changes in thermal energy demand.

[0189] The present embodiment provides a control method for a water heat / cold energy cross-industry recycling system. The present embodiment first monitors the temperature of the server cabinet and increases the operating power of the high-temperature heat pump system when it exceeds a preset temperature threshold, thereby effectively preventing the server from performance degradation or damage due to overheating. When the server cabinet generates excess heat, the operating power of the high-temperature water source heat pump unit is increased to recover the excess heat, thereby improving the energy efficiency of the data center. By monitoring the parameter changes of the heat release equipment to reflect its thermal energy demand and adjusting the operating power of the high-temperature water source heat pump unit accordingly, it can be ensured that the system can always meet the thermal energy demand and maintain a stable operating state.

[0190] Based on the first embodiment, the fourth embodiment of the present application proposes a control method for a water heat / cold energy cross-industry recycling system, referring to Figure 5 The control method of the water heat / cold energy cross-industry recycling system also includes:

[0191] Step S40, monitoring the liquid level of the heat storage tank and the liquid level of the return water tank in real time through the liquid level sensor of the liquid level control system.

[0192] By monitoring the liquid level of the heat storage tank and the return water tank, the tanks can be prevented from overflowing or drying up, ensuring the safe operation of the system.

[0193] As an optional implementation, liquid level sensors are installed in the heat storage tank and the return water tank, and liquid level data is collected in real time through the liquid level sensors and transmitted to the control unit.

[0194] Optionally, according to the liquid level and preset control logic, the control signal is sent to the circulating water pump to adjust the working state of the circulating water pump. The control logic is used to guide the control of the circulating water pump, and determines whether the working state of the circulating water pump needs to be adjusted according to the data of the liquid level sensor. The control signal is a signal for adjusting the working state of the circulating water pump, and is generated and sent to the circulating water pump according to the data of the liquid level sensor and the control logic to adjust the working state of the circulating water pump.

[0195] Step S50, if the liquid level of the heat storage tank is higher than a preset maximum liquid level, and / or the liquid level of the return water tank is lower than a preset minimum liquid level, send the control signal to the circulating water pump to control the circulating water pump to transport the high-temperature return water in the heat storage tank to the return water tank.

[0196] To prevent the water level in the water storage tank from being too high, which may cause the tank to overflow or affect the normal operation of the system, and to prevent the water level in the return water tank from being too low, which may cause the water pump to run idle, the system to be short of water, or affect the subsequent water treatment process. When the liquid level of the heat storage tank is higher than the preset maximum liquid level and / or the liquid level of the return water tank is lower than the preset minimum liquid level, the water level of the heat storage tank and the return water tank can be effectively adjusted by controlling the circulating water pump to transport the excess water source of the heat storage tank to the return water tank, ensuring the safe and stable operation of the system.

[0197] In this embodiment, the preset maximum liquid level is a preset upper limit of the liquid level to prevent the heat storage tank from overflowing, and the preset minimum liquid level is a preset upper limit of the liquid level to ensure the normal operation of the return water tank.

[0198] Exemplarily, a liquid level sensor is used to monitor the liquid level of the return water pool in real time, and the monitored liquid level is compared with a preset minimum liquid level. If the liquid level is lower than the preset minimum liquid level, a circulating water pump is started to draw water from the heat storage tank to replenish the return water pool.

[0199] Exemplarily, a liquid level sensor is used to monitor the liquid level of the heat storage tank in real time, and the monitored liquid level is compared with a preset maximum liquid level. If the liquid level is higher than the preset maximum liquid level, a circulating water pump is started to transport excess water in the heat storage tank to the return water tank.

[0200] Optionally, the liquid level is continuously monitored and adjusted until the liquid level in the return water tank rises to within a preset range.

[0201] Step S60, if the liquid level of the heat storage tank is lower than the preset minimum liquid level, and / or the liquid level of the return water tank is higher than the preset maximum liquid level, the control signal is sent to the circulating water pump to control the circulating water pump to transport the low-temperature return water in the return water tank to the heat storage tank.

[0202] To prevent the water level in the return water pool from being too high, which may cause the pool to overflow or affect the normal operation of the system, and to prevent the water level in the water storage tank from being too low, which may cause the water pump to run idle, the system to be short of water, or affect the subsequent water treatment process. When the liquid level in the return water pool is higher than the preset maximum liquid level and / or the liquid level in the heat storage tank is lower than the preset minimum liquid level, the excess water in the return water pool is transferred to the heat storage tank by controlling the circulating water pump, which can effectively adjust the water level of the heat storage tank and the return water pool to ensure safe and stable operation of the system.

[0203] In this embodiment, the preset maximum liquid level is a preset upper limit of the liquid level to prevent the reflux pool from overflowing, and the preset minimum liquid level is a preset upper limit of the liquid level to ensure the normal operation of the heat storage pool.

[0204] Exemplarily, a liquid level sensor is used to monitor the liquid level of the return water pool in real time, and the monitored liquid level is compared with a preset maximum liquid level. If the liquid level is higher than the preset maximum liquid level, a circulating water pump is started to transport excess water in the return water pool to the heat storage tank.

[0205] Exemplarily, a liquid level sensor is used to monitor the liquid level of the heat storage tank in real time, and the monitored liquid level is compared with a preset minimum liquid level. If the liquid level is lower than the preset minimum liquid level, a circulating water pump is started to draw water from the return water tank to replenish the heat storage tank.

[0206] Optionally, the liquid level is continuously monitored and adjusted until the liquid level in the return water reservoir drops to within a preset range.

[0207] The present embodiment provides a control method for a cross-industry recycling system of water heat / cold energy. The present embodiment first monitors the liquid levels of a heat storage tank and a return water tank in real time through a liquid level sensor, automatically senses changes in the water level, and determines whether it is necessary to adjust the working state of a circulating water pump according to a preset control logic, thereby realizing automatic water level control, so that the liquid level of the return water tank is always maintained within a preset range, thereby maintaining stable operation of the system and improving the operating efficiency of the system.

[0208] For example, in order to help understand the implementation process of the control method of the water heat / cold energy cross-industry recycling system obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 6 , Figure 6 An overall schematic diagram of a water heat / cold energy cross-industry recycling system is provided, specifically:

[0209] In this embodiment, the water heat / cold energy cross-industry recycling system is used for heat energy recycling between a data center and a sewage treatment plant.

[0210] Monitor the operating status of computer equipment in the data center. The heat generated by the equipment is taken away by the cold plate liquid cooling system. The coolant circulates through the cold plate and contacts the heat-generating components of the computer equipment, absorbing the heat.

[0211] Optionally, the coolant includes an inner circulation coolant and an outer circulation coolant. The inner circulation coolant absorbs the heat generated by the computer equipment, the temperature rises to 51 degrees, and then passes through the cooling distribution unit and exchanges heat with the outer circulation coolant through the heat exchanger. The outer circulation coolant receives the heat transferred by the inner circulation coolant, the temperature rises to 46 degrees, and transfers the heat to the water source of the heat storage tank.

[0212] Optionally, the inter-row air conditioner obtains cooling water from the cold storage water tank to process the ambient heat and the heat not taken away by the liquid cooling system. When the water temperature in the cold storage water tank rises, the low-temperature heat pump starts to reduce the water temperature to a set range.

[0213] Furthermore, the heat generated during the operation of the low-temperature heat pump is recovered to the recirculation pool, further improving the efficiency of thermal energy utilization.

[0214] The heat storage tank stores heat from the external circulating coolant, and uses the 46-degree high-temperature water in the heat storage tank as the heat source of the high-temperature water source heat pump unit. The high-temperature water source heat pump unit in the heat storage tank raises the temperature of the water source in the heat storage tank to 80 degrees.

[0215] The 80-degree high-temperature water source with increased temperature is transported to the sludge drying equipment of the sewage treatment plant. The sludge drying equipment uses the heat of the high-temperature water source to dry the sludge. After absorbing the heat, the sludge drying equipment generates a 36-degree low-temperature water source, which flows back to the return water pool through the pipeline system.

[0216] According to the liquid level of the return water pool, a control signal is sent to the circulating water pump, and the low-temperature water source in the return water pool and the high-temperature water source in the heat storage tank are circulated through the circulating water pump.

[0217] Optionally, the return water pool receives water from the cold end of the high-temperature heat pump, the air conditioning heat pump and the grey water supply to maintain the stability of the water volume and temperature.

[0218] The entire process is from heat generation to heat recovery in the data center, including the role of inter-row air conditioning, water temperature regulation of the cold storage tank, heat recovery of the low-temperature heat pump, and heat supply for sludge drying, achieving efficient utilization and circulation of heat while maintaining the thermal energy requirements of the data center and the sludge drying process.
