Taking running on a computer terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a computer terminal according to a heat exchange control method of an embodiment of the present application. Figure 1 As shown, the computer terminal may include one or N ( Figure 1 The computer terminal includes a processor 102 (only one is shown in the figure) (the processor 102 may include but is not limited to a processing device such as a microprocessor (Central Processing Unit, CPU) or a programmable logic device (Field Programmable Gate Array, FPGA)) and a memory 104 for storing data, wherein the computer terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal.

In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0031] In this embodiment, a heat exchange control method is provided. Figure 2 is a flow chart of a heat exchange control method according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps S202-S206:

[0032] Step S202: determining the circulation parameters of the initial circulating water in the plant factory area, wherein the circulation parameters at least include: the flow rate of the initial circulating water, the real-time temperature of the initial circulating water, and the waste heat heating position corresponding to the initial circulating water;

[0033] Step S204: determining a temperature adjustment strategy for the initial circulating water according to the circulation parameters and preset heat exchange modes corresponding to different sub-areas in the plant factory area;

[0034] Optionally, the plant factory area is divided into four sub-areas: seedling area, growth area, maturation area and picking area, and each area has different temperature requirements. For example, the seedling area needs to be maintained at a temperature of about 25°C, while the maturation area requires a slightly higher temperature, such as 28°C, to promote the ripening of the fruit. The system collects data in real time through the water level and water temperature intelligent dual-control sensors in each area and sends the information to the plant factory intelligent temperature control system. When the system detects that the water temperature in the seedling area is lower than the set value, it will automatically open the solenoid valve leading to the seedling area and adjust the circulating water flow to the preset value to ensure that the circulating water is fully heat exchanged with the nutrient solution or pure water in the area, and the water temperature is raised to about 25°C. At the same time, the system will monitor the temperature of the growth area. If the water temperature in the growth area has met the conditions (for example, 27°C), the solenoid valve leading to the growth area is closed to avoid overheating, and the circulating water is directed to the maturation area that requires more heat until the water temperature in the maturation area also reaches the preset value (such as 28°C). The picking area may not need additional heat at certain times, so the system will intelligently decide whether to open the solenoid valve and introduce circulating water based on the real-time temperature of the area and the growth needs of the plants. In this way, the system can automatically adjust the flow and temperature of the initial circulating water according to the real-time needs of each sub-area of ​​the plant factory, and achieve precise temperature control management, which not only meets the specific temperature needs of plants at different growth stages, but also avoids energy waste caused by improper temperature control, and improves the efficiency of energy utilization of the entire system.

[0035] Step S206: Use the temperature adjustment strategy to control the heat exchange of different sub-areas, and synchronously update the change value of the initial circulating water, and display the change value on the visual data interface corresponding to the plant factory area.

[0036] Through the above steps, the circulation parameters of the initial circulating water in the plant factory area are determined, wherein the circulation parameters include at least: the flow rate of the initial circulating water, the real-time temperature of the initial circulating water, and the waste heat heating position corresponding to the initial circulating water; the temperature adjustment strategy of the initial circulating water is determined according to the circulation parameters and the preset heat exchange methods corresponding to different sub-areas in the plant factory area; the temperature adjustment strategy is used to control the heat exchange of different sub-areas, and the change value of the initial circulating water is synchronously updated, and the change value is displayed on the visual data interface corresponding to the plant factory area. The above technical solution is adopted to solve the problems of high energy consumption and operating costs of plant factories. Furthermore, by dynamically adjusting the flow rate and heating strategy of the initial circulating water, fine temperature control of the plant factory area is achieved, thereby reducing the temperature control cost of the plant factory area and improving energy utilization efficiency.

[0037] In an exemplary embodiment, a temperature adjustment strategy for circulating water is determined based on circulation parameters and preset heat exchange modes corresponding to different sub-areas in a plant factory area, including: when the heat exchange mode is heat exchange in a barrel, determining the liquid levels of multiple liquid containers in different sub-areas and water temperature data of each liquid container, wherein the multiple liquid containers include at least: a pure water barrel, a liquid distribution barrel, and a liquid storage barrel; counting the circulating water flow rate corresponding to the first target liquid container among the multiple liquid containers that passes through the initial circulating water; controlling the outlet flow rate of other liquid containers except the target liquid container and the liquid level in other liquid containers based on the circulating water flow rate, and determining whether to perform secondary heating on the circulating water according to the outlet water temperature of the outlets on the other liquid containers; and generating a first temperature adjustment strategy for circulating water according to the control result and the determination result.

[0038] Optionally, when the system presets the heat exchange mode as heat exchange in the barrel, the system first determines the liquid level and water temperature data of the pure water barrel, the liquid distribution barrel, and the liquid storage barrel in different sub-areas. For example, the pure water barrel in the nursery area requires the water level to be above 80% and the water temperature to be maintained at 25°C; while the liquid storage barrel in the mature area requires the water level to be 75% and the water temperature to reach 28°C. The system records the initial flow rate of the circulating water into the first target liquid container (such as the liquid distribution barrel in the growth area), assuming it is 200L / min. Subsequently, the system dynamically controls the outlet flow and water level of other liquid containers except the liquid distribution barrel to keep their water temperature stable. For example, after the liquid distribution barrel in the growth area completes the heat exchange, the system will automatically adjust the outlet flow rate to 180L / min according to the water level and water temperature data of the subsequent container (such as the liquid storage barrel in the mature area) to avoid the water temperature rising too quickly. The system monitors the water temperature of the outlet in real time. If the outlet water temperature of the liquid storage barrel in the mature area is lower than 28°C, the system will automatically reheat the circulating water until the temperature requirement is met. According to the above control results and the result of determining whether secondary heating is needed, the system generates a first adjustment strategy. Through real-time monitoring and adjustment, the system avoids excessive or insufficient heat input, reduces energy waste, and improves overall energy efficiency.

[0039] In an exemplary embodiment, a first temperature adjustment strategy for circulating water is generated according to the control result and the determination result, including: when the outlet water temperature is greater than or equal to a preset target temperature value and the liquid water level is greater than or equal to a preset water level threshold, a first adjustment strategy for prohibiting secondary heating of circulating water and / or increasing the water flow rate of circulating water is obtained; when the outlet water temperature is greater than or equal to the preset target temperature value and the liquid water level is less than the preset water level threshold, a first adjustment strategy for determining to increase the water flow rate of circulating water is obtained; when the outlet water temperature is less than the preset target temperature value and the liquid water level is less than the preset water level threshold, a first adjustment strategy for generating an alarm message is obtained, wherein the alarm message is used to start periodic monitoring of the current sub-area; when the outlet water temperature is less than the preset target temperature value and the liquid water level is greater than or equal to the preset water level threshold, a first adjustment strategy for setting a heating point for secondary heating of circulating water on the liquid connection channel after the liquid container where the outlet water temperature is first reduced is obtained; when the outlet water temperature is less than the preset target temperature value or the liquid water level is less than the water level threshold, a first adjustment strategy for generating an alarm message is obtained, wherein the alarm message is used to start a maintenance task for the current plant factory area.

[0040] Optionally, in a plant factory, if the system presets the heat exchange mode as heat exchange in the barrel, the target temperature is 27°C, and the preset water level threshold is 70%. The system monitors the outlet temperature and water level of each sub-area in real time, and automatically generates the first adjustment strategy based on the following conditions: When the outlet water temperature reaches or exceeds 27°C and the water level is above 70%, the system generates the first adjustment strategy of "prohibiting secondary heating of circulating water and maintaining the current water flow rate", avoiding excessive energy consumption. If the outlet water temperature reaches or exceeds 27°C, but the water level is below 70%, the system will automatically identify and increase the water flow rate of circulating water to quickly raise the water level to 70% while ensuring the stability of the water temperature. This adjustment strategy is called "increasing the circulating water flow rate". When the outlet water temperature is lower than 27°C and the water level is also lower than 70%, the system generates an alarm message and automatically starts the periodic monitoring of the current sub-area to check whether there is any equipment failure or environmental abnormality. This strategy is called "periodic monitoring alarm". If the outlet water temperature is lower than 27°C for the first time, but the water level is above 70%, the system will automatically set a heating point on the connecting channel between the subsequent liquid containers to quickly raise the water temperature to 27°C by heating the circulating water. This strategy is called "secondary heating heating point". When the outlet water temperature is lower than 27°C or the water level is lower than 70%, the system generates an alarm message and automatically starts a maintenance task for the entire plant factory area to check and repair equipment that may cause problems. This strategy is called "maintenance task alarm". Through this intelligent adjustment strategy, the system can respond to environmental changes in each sub-area of ​​the plant factory in real time, automatically adjust the temperature and flow of circulating water, ensure that plant growth conditions are always in the best state, optimize energy utilization efficiency, avoid unnecessary energy waste, and effectively prevent environmental out-of-control and equipment failure, ensuring the stable operation and economic benefits of the plant factory.

[0041] In an exemplary embodiment, a temperature adjustment strategy for circulating water is determined based on circulation parameters and preset heat exchange methods corresponding to different sub-areas in a plant factory area, including: when the heat exchange method is external heat exchange, determining the real-time outlet water temperature of each of a plurality of liquid containers in different sub-areas; when the real-time outlet water temperature reaches a preset target temperature value or reaches an upper working limit temperature value, issuing a first instruction through the control system of the plant factory area, wherein the first instruction is used to close a water valve for circulating water to flow into the current area; and generating a second temperature adjustment strategy for circulating water based on the first instruction.

[0042] Exemplarily, the plant factory area is divided into an illumination zone, a growth zone, and a maturation zone, and the preset target temperatures of each sub-zone are 25°C, 27°C, and 29°C, respectively. The system preset heat exchange mode is external heat exchange, that is, the heat exchange between circulating water and nutrient solution is carried out in a heat exchanger outside the container. When the real-time outlet water temperature of the illumination zone reaches 25°C, the control system automatically closes the circulating water inflow valve of the zone, and generates a second adjustment strategy at the same time to ensure that the illumination zone is not subjected to unnecessary secondary heating to save energy. In the growth zone, assuming that the system detects that the outlet water temperature reaches 27°C, it will also automatically close the circulating water valve to prevent overheating. If the temperature starts to drop afterwards, the system will automatically open the valve and resume the inflow of circulating water to keep the temperature stable at around 27°C. When the real-time outlet water temperature of the maturation zone reaches or exceeds 29°C, the system immediately closes the circulating water valve and generates a second adjustment strategy to avoid damage to plants or waste of resources due to excessive temperature. If the outlet water temperature of any area is close to the upper limit of the working temperature (for example, set to 30°C for safety), the system will close the circulating water valve in advance and generate a second adjustment strategy to prevent the temperature from exceeding the safety range and protect the equipment. This intelligent temperature adjustment strategy effectively maintains the temperature of each sub-area within the ideal growth range through real-time monitoring and precise control, while significantly reducing energy consumption and improving the overall efficiency and safety of the system.

[0043] In an exemplary embodiment, after using the temperature adjustment strategy to control the heat exchange of different sub-areas, synchronously updating the change value of the initial circulating water, and displaying the change value on the visual data interface corresponding to the plant factory area, the above method also includes: obtaining the operating temperature values ​​set by the management object for different sub-areas; when the real-time temperature values ​​of different sub-areas are lower than the operating temperature values, calculating the temperature difference between the real-time temperature value and the operating temperature value; determining the total exchange time of the heat exchange based on the temperature difference and the response time of the control system of the plant factory area.

[0044] Optionally, a plant factory contains three sub-areas: the nursery area, the growth area, and the maturation area, with operating temperature values ​​set at 24°C, 27°C, and 30°C, respectively. On a winter morning, the control system detected that the real-time temperature in the nursery area was 22°C, the real-time temperature in the growth area was 26°C, and the real-time temperature in the maturation area was 29°C. The system automatically calculates the temperature difference, which is 2°C, 1°C, and 1°C, respectively. The system preset response time is 10 minutes, that is, within 10 minutes, the system can adjust the real-time temperature according to the temperature and flow of the circulating water so that the real-time temperature reaches the operating temperature value. Based on the temperature difference and response time, the system determines the total heat exchange time to ensure that the temperature of each area returns to the set value within the specified time. Specifically, for the nursery area, a difference of 2°C means that a longer heat exchange is required to make up for the temperature difference, and the system may set a total exchange time of 20 minutes (assuming that it can be increased by 0.1°C per minute). Due to the small difference in the growth area and the maturation area, the total exchange time may be 15 minutes and 10 minutes, respectively. During the heat exchange process, the system monitors temperature changes in real time. Once the set operating temperature is reached, the heat exchange duration is adjusted immediately and the circulating water valve is closed in advance to prevent excessive temperature rise. In addition, the system also records the total heat exchange duration for subsequent system optimization and maintenance to ensure that the plant factory can operate stably and long-term. Through precise calculations and intelligent decision-making, the system can effectively manage and optimize the heat exchange process, ensuring that the temperature of each sub-area of ​​the plant factory is controlled within the ideal range, while achieving efficient use of energy and automated management.

[0045] In an exemplary embodiment, before determining the total exchange time of the heat exchange based on the temperature difference and the response time of the control system of the plant factory area, the above method also includes: when the response time is greater than the preset maximum response time limit, sending a second instruction to the temperature control equipment in the plant factory area; when the response time is less than or equal to the preset maximum response time limit, synchronizing the remaining response time to the visual data interface corresponding to the plant factory area.

[0046] Optionally, in a plant factory, the preset maximum temperature adjustment response time is 30 minutes, that is, the system needs to adjust the temperature to the target value within 30 minutes. The plant factory area is divided into three sub-areas, namely, the seedling area, the growth area, and the maturation area. Suppose that one morning, the system detects that the real-time temperature in the growth area is lower than the set value, and the temperature needs to be increased by heat exchange. The system first calculates the theoretical response time required to reach the set temperature based on the current circulating water temperature and flow. For example, if the current temperature is 23°C and the target temperature is 27°C, the system evaluates that it takes 35 minutes to reach the target temperature, which exceeds the preset maximum response time limit of 30 minutes. After the response time exceeds the limit, the system immediately sends a second instruction to the multi-split air-conditioning unit in the growth area to start the auxiliary heating mode to accelerate the temperature increase process. In this way, the air conditioning system and the circulating water system work simultaneously to ensure that the temperature reaches 27°C within the preset 30 minutes. If the system evaluates that the temperature regulation response time of the nursery area is 25 minutes, that is, within the preset maximum response time, it will not start additional temperature regulation equipment, but will synchronously display the remaining 5 minutes of response time on the visual data interface of the plant factory, so that operators can monitor the system operation status in real time. Through accurate evaluation and timely activation of auxiliary equipment, it can ensure that the temperature environment of the plant factory is maintained within the most suitable range for plant growth under various circumstances. At the same time, through the synchronous update of the visual data interface, the transparency and convenience of system management are enhanced.

[0047] Obviously, the embodiments described above are only some embodiments of the present application, not all embodiments. In order to better understand the method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0048] An optional embodiment of the present application provides a method for cascade utilization of waste heat from circulating water of a plant factory coupled to a thermal power plant, in order to solve the problems of high energy consumption and operating costs of plant factories. This method uses intelligent control and heat exchange technology to efficiently recycle waste heat from circulating water of thermal power plants, provide a stable heat source for plant factories, and optimize energy utilization efficiency. The system adopts a flexible heat exchange method inside and outside the barrel, combined with a water level and water temperature dual control sensor and an intelligent temperature control system for a plant factory, to achieve refined automatic adjustment of circulating water flow, water temperature, and flow direction, ensuring that each cultivation area can be maintained within an ideal temperature range. This solution also has a response time management and early warning mechanism, which can automatically generate adjustment strategies based on real-time temperature data and preset conditions, and start auxiliary temperature regulation equipment when necessary to quickly respond to temperature changes, thereby ensuring efficient operation and energy conservation of plant factories.

[0049] As an optional implementation, Figure 3is a schematic diagram of a plant factory coupled with a thermal power plant circulating water waste heat cascade utilization system according to an embodiment of the present application, such as Figure 3 As shown, the above system at least includes: a turbine condenser cooling water system, a filter, a flow and water temperature sensor, a water level and water temperature intelligent dual control sensor, a plant factory intelligent temperature control system and a nutrient solution circulation control system, a solenoid valve, a pure water bucket, a liquid distribution bucket, a liquid storage bucket and a cultivation room, etc. The above system can specifically perform the following steps:

[0050] Step 1: Steam works and waste heat is generated. After the superheated steam in the thermal power plant works in the steam turbine, the exhaust steam is cooled by circulating water in the condenser and converted into condensate. The circulating water absorbs heat in this process and becomes a resource containing waste heat. The condensate then passes through the condensate pump, low-pressure heater, deaerator and other equipment, and is processed by the feed water pump and high-pressure heater, and re-enters the thermal cycle as boiler feed water.

[0051] Step 2: Circulating water pretreatment and monitoring. The circulating water that has absorbed the exhaust heat passes through a filter to remove impurities to ensure that the water quality is suitable for further heat exchange. The filtered circulating water enters the waste heat recovery system and its status is monitored by flow and water temperature sensors. These sensors record the initial flow and temperature of the circulating water, and the information is uploaded to the plant factory intelligent temperature control system.

[0052] Optionally, the filter is not limited to various forms such as pipeline filters and sedimentation tanks. The system is not limited to various forms such as open circulation and closed circulation.

[0053] Step 3: Intelligent temperature control and valve adjustment. The intelligent temperature control system of the plant factory analyzes the data uploaded by the sensor and generates control signals according to the climate conditions of the project site and the temperature control needs of the plant factory. The signals include adjusting the switch state of the solenoid valve and controlling the flow direction and flow of the circulating water to optimize the distribution and utilization of heat energy.

[0054] Optionally, data collected by various water level, water temperature and flow sensors are uploaded to the plant factory intelligent temperature control system via RS485 or other communication methods. The control center analyzes the signals and generates corresponding control signals to control the water level, water temperature, solenoid valve opening, etc., so that various environmental factors are kept within the optimal range suitable for plant growth.

[0055] Step 4: Cascade utilization of circulating water waste heat. According to the instructions of the control system, the circulating water enters the waste heat recovery system through the solenoid valve. The system uses the following two methods to exchange heat with pure water or nutrient solution. The difference between the two methods lies in whether the circulating water pipeline is in direct contact with the nutrient solution. The details are as follows:

[0056] (1) Use the in-barrel heat exchange method. Confirm that the liquid level and water temperature data of the pure water barrel, liquid distribution barrel, and liquid storage barrel are within the normal range, set the circulating water flow rate flowing through the pure water barrel, and the circulating water flows through the pure water barrel, liquid distribution barrel, and liquid storage barrel in turn. The barrel is equipped with an intelligent dual-control sensor for water level and water temperature, which activates the alarm and protection when the liquid water level or water temperature is too low or too high. If the water level in the barrel is at the lower limit or the water temperature has reached the upper limit and no circulating water heating is required, the circulating water inlet valve in this link is closed, and the circulating water flows to the next barrel to continue heat exchange, and finally flows through each cultivation room to complete the gas-liquid heat exchange. Figure 4 As shown, Figure 4 This is a schematic diagram of a heating method and temperature control in a circulating water waste heat barrel according to an embodiment of the present application. Figure 4 It can be seen that the circulating water first enters through the inlet, then flows through the coil base and exchanges heat with the liquid in the barrel. The upper and lower limits of the water level in the barrel are monitored by the water level and water temperature dual control sensors to prevent the water level from being too low or overflowing. After the circulating water exchanges heat with the liquid in the barrel, the circulating water flows out of the barrel through the outlet. The intelligent temperature control system generates and executes a temperature adjustment strategy based on the real-time temperature and flow of the initial circulating water, as well as the water temperature and water level of the liquid in the barrel, to ensure that the temperature in the plant factory area is appropriate and to achieve efficient use of the circulating water waste heat of the thermal power plant.

[0057] Optionally, the filtered circulating water enters the pure water bucket, nutrient solution preparation bucket or nutrient solution storage bucket from the bottom to the top through the heat exchange pipe and performs sufficient convection heat exchange with the nutrient solution, which is a liquid-liquid convection heat exchange method. The heat exchange pipe is not limited to straight pipe type, spiral coil type, etc. The heat exchange coil in the circulating water bucket is made of acid and alkali resistant, temperature resistant (around 50°C), easy to support and not easy to deform materials.

[0058] Optionally, the cooling circulating water can flow freely through the pure water barrel, liquid distribution barrel, liquid storage barrel, and cultivation room through the pipe. It can enter and exit independently, and different links can be connected in series and parallel. The flow path is controlled by an electromagnetic valve, and manual / automatic mode can be selected. In automatic mode, automatic control is achieved through the plant factory intelligent temperature control system.

[0059] (2) Use an external heat exchange method. Confirm that the liquid level and water temperature data of the pure water barrel, liquid distribution barrel, and liquid storage barrel are within the normal range. Within the response time before the pure water or nutrient solution is transported from the barrel to the next link or cultivation room (such as within 1 minute), open the circulating water valve and complete the heat transfer exchange in the heat exchanger (plate heat exchanger or other form). A water temperature sensor is installed at the outlet of the pure water or nutrient solution heat exchange. When the outlet water temperature reaches the target value or upper limit, a command is issued through the plant factory intelligent temperature control system to close the circulating water valve and terminate the heat exchange. Figure 5 As shown, Figure 5 This is a schematic diagram of a circulating water waste heat barrel external heating method and temperature control according to an embodiment of the present application. Figure 5It can be seen that the circulating water enters the heat exchanger through the inlet and exchanges heat with the liquid in the nutrient solution barrel or pure water barrel. Pure water or nutrient solution enters the heat exchanger through the pure water or nutrient solution inlet and contacts the circulating water to achieve the purpose of temperature adjustment. After heat exchange, the circulating water flows out through the circulating water outlet. The water temperature and flow sensor monitors the real-time temperature and flow of the initial circulating water in the heat exchanger to ensure the efficiency and accuracy of heat exchange. The intelligent temperature control system generates and executes the temperature adjustment strategy based on the feedback of the sensor. For example, when the outlet water temperature is lower than the preset target temperature value, the circulating water is reheated through the heating point set on the liquid connection channel.

[0060] Step 5: Optimize the cultivation room environment. The circulating water after heat exchange enters the cultivation room and provides a suitable temperature environment for plant growth through air-liquid convection heat exchange. The staggered baffles or spoilers installed in the heat exchange pipes in the cultivation room greatly enhance the heat exchange efficiency between water and air by increasing the turbulence of the water flow and extending the residence time, ensuring the full utilization of the waste heat of the circulating water, increasing the heat exchange area and residence time, and thus improving the heat exchange efficiency. The system can flexibly select the flow path of the circulating water to meet different temperature control requirements. Figure 6 As shown, Figure 6 It is a schematic diagram of a heat exchange pipeline for circulating water in a cultivation room according to an embodiment of the present application. Figure 6 The essential process of circulating water heat exchange in the cultivation room is intuitively displayed. Circulating water flows in from the main system of the thermal power plant, and directly exchanges heat with the indoor air through the carefully arranged heat exchange pipes in the cultivation room. After the heat exchange, it flows out from the circulating water outlet. The setting of the circulating water heat exchange pipe ensures the precise adjustment of the temperature and reduces unnecessary energy waste.

[0061] Step 6: System response and auxiliary heating mechanism. The intelligent temperature control system of the plant factory continuously monitors the temperature and flow of the circulating water and the temperature and humidity of the cultivation room environment. The circulating water flow and water temperature data are transmitted to the intelligent temperature control system of the plant factory in real time. When the temperature of the plant factory is lower than the set value and heating is required, the circulating water waste heat utilization system is started first to use the circulating water waste heat to heat the nutrient solution and the planting environment. According to the target heating amount and target temperature, the initial circulating water flow and water temperature data, the system response time is calculated. If the circulating water waste heat utilization system responds too slowly and exceeds the maximum response time limit, the original plant factory multi-split air conditioning unit is started to achieve auxiliary heating until the set target value is reached. At the same time, the system can evaluate the utilization efficiency of the circulating water waste heat in real time by obtaining the flow and water temperature data at the inlet and outlet of the circulating cooling water flowing through the plant factory. The parameter data such as the circulating water flow, water temperature, and efficiency of each node can be intuitively displayed on the large screen through the PLC control center connected to the control system, which is convenient for real-time monitoring and optimization of control strategies.

[0062] It should be noted that the location of the circulating water waste heat heating can be freely selected according to the climatic conditions of the project site and the differences in the plant factory system. In addition, whether it is heat exchange in the barrel or outside the barrel, the heat exchanger structure needs to be carefully designed, such as using baffles to increase turbulence and optimizing the coil layout to improve heat exchange efficiency and reduce energy loss. The selection of heat exchangers should take into account the maintenance costs of long-term operation. At the same time, the system needs to have a fast response capability and be able to adjust the circulating water flow and heating strategy in real time according to temperature changes. When the system response time is not enough to quickly adjust the ambient temperature, the timely start-up of auxiliary temperature control equipment (such as multi-split air-conditioning units) is necessary, but the use of auxiliary equipment needs to be reasonably planned to avoid over-reliance and unnecessary energy consumption.

[0063] In summary, the optional embodiments of the present application extract the circulating water waste heat that is neglected in the thermal power generation process, use filters to remove impurities, and ensure water quality safety; by arranging flow and water temperature sensors, water level and water temperature intelligent dual control sensors and other precision control components, the system operation status is monitored and adjusted in real time; by coupling the plant factory intelligent temperature control system, the refined control of waste heat recovery and utilization is realized; and the heat exchange method inside or outside the barrel is adopted, and the electromagnetic valve, pure water barrel, liquid distribution barrel, liquid storage barrel and the circulating water pipeline in the cultivation room are used to provide a stable heat source for the plant factory, while avoiding the high energy consumption problem of traditional heating methods. The energy consumption of the plant factory in environmental control is greatly reduced, especially in the winter season when the heating demand is high, and the waste heat resources of the thermal power plant are effectively utilized, which not only reduces the operating cost, but also improves the comprehensive energy utilization efficiency of the thermal power plant. At the same time, through intelligent control, the efficient allocation of resources and the optimization of energy utilization are realized, which is of great value to the sustainable development of the comprehensive energy system.
