[0074] S301, automatically starting the heat storage and release dynamic control system according to a preset time interval.

[0075] Specifically, according to a preset time interval, for example, a preset time interval of 30 minutes, the following procedures and control actions of the heat storage and release dynamic control system are automatically started.

[0076] S302, determining the heating demand of the target area according to the environmental parameters, building parameters and target required temperature of the target area, and determining a preset demand range according to the heating demand.

[0077] Specifically, after determining the target area, obtain the environmental parameters of the target area, for example, obtain the average temperature, minimum temperature and maximum temperature of the winter in the past few years through the local meteorological department; understand the relative humidity in the area in winter to evaluate the impact on heating efficiency; understand the dominant wind direction and wind speed in winter to evaluate the impact on building heat loss. Obtain the building parameters of the target area, for example, understand the construction age of each building in the community to evaluate its insulation performance; understand the insulation materials and thickness of the walls, roofs and floors of the building; understand the orientation of the building to evaluate the impact of solar radiation on indoor temperature. The indoor target demand temperature can be determined according to the living habits and comfort requirements of local residents, such as keeping the room temperature between 18℃-22℃. After obtaining the environmental parameters, building parameters and target demand temperature of the target area, calculate the heating demand of the target area according to the environmental parameters, building parameters and target demand temperature of the target area, and determine the preset demand range according to the heating demand, for example, the preset demand range is 10% to 500% of the heating demand. In this way, the climate model can be closely combined with the regulation of the heating system, and the heat load demand can be estimated in advance by using the building thermal physics model and the climate prediction model. Based on the system operating status, optimize the heat storage and release strategies, reduce unnecessary energy waste, and further improve the operating efficiency and responsiveness of the heating system.

[0078] S303, obtaining the actual heating power of all heat exchange devices, and selecting a target heat exchange device from all heat exchange devices according to a preset demand range; wherein the actual heating power of the target heat exchange device is within the preset demand range.

[0079] Specifically, the actual heating power of each heat exchanger is obtained to obtain the actual heating power of all heat exchangers, the preset demand range is compared with the actual heating power of all heat exchangers, and the heat exchangers whose actual heating power is within the preset demand range are screened out, and the heat exchangers are used as target heat exchangers.

[0080] S304: for each target heat exchange device, verify whether the target heat exchange device has heat storage capacity.

[0081] Specifically, after obtaining each target heat exchanger, determine whether each target heat exchanger has heat storage capacity, that is, verify whether the target heat exchanger has heat storage capacity by monitoring the temperature of the hot water in the shunt pipe and the cold water in the return branch after mixing. For example, after the heat storage and release dynamic control system has been running for a period of time, observe and record the hot water flow in the shunt pipe and the mixed water temperature. Set a preset return water temperature threshold. If the mixed water temperature is lower than this threshold, it can be considered that the target heat exchanger has heat storage capacity because it can store excess heat in the system for emergency use. If the mixed water temperature is higher than the preset return water temperature threshold, it may be necessary to further investigate the cause, such as checking the working efficiency of the heat exchanger, the temperature control of the water supply branch, etc. After confirming that there is no fault or abnormality, it can be considered that the target heat exchanger does not have significant heat storage capacity under the current conditions.

[0082] S305: In response to the target heat exchange device having heat storage capacity, it is determined whether the target heat exchange device has an over-supply of heat according to the actual heating power and heating demand of the target heat exchange device.

[0083] Specifically, when the target heat exchange equipment has the heat storage capacity, the actual heating power of the target heat exchange equipment can be compared with the heating demand. According to the actual heating power of the target heat exchange equipment and the heating demand, it can be judged whether the target heat exchange equipment has an oversupply of heat, and the opening valve corresponding to the target heat exchange equipment can be controlled in time to make the actual heating power of the target heat exchange equipment meet the heating demand.

[0084] S306, in response to the target heat exchange device having an over-supply of heat, controlling the opening valve corresponding to the target heat exchange device to increase the opening according to a preset percentage, wherein the preset percentage can be set according to actual conditions, for example, the preset percentage is 10%.

[0085] Specifically, when the target heat exchange equipment has an oversupply of heat, it can be said that the actual heating power of the target heat exchange equipment is greater than the heating demand. At this time, the opening valve corresponding to the target heat exchange equipment is controlled to increase the opening according to a preset percentage to reduce the heat output so that the actual heating power of the target heat exchange equipment meets the heating demand. At the same time, the heat storage capacity of the target heat exchange equipment can be used to store excess heat for emergency use. The opening range of the opening valve is 0-100%.

[0086] S307: In response to the target heat exchange device not having a heat oversupply situation, determine whether the target heat exchange device has a heat undersupply situation according to the actual heating power and heating demand of the target heat exchange device.

[0087] Specifically, when the target heat exchange equipment does not have an oversupply of heat, the actual heating power of the target heat exchange equipment can be compared with the heating demand. According to the actual heating power of the target heat exchange equipment and the heating demand, it can be determined whether the target heat exchange equipment has an undersupply of heat, and the opening valve corresponding to the target heat exchange equipment can be controlled in time to make the actual heating power of the target heat exchange equipment meet the heating demand.

[0088] S308, in response to the target heat exchange device having a heat shortage, controlling the opening valve corresponding to the target heat exchange device to reduce the opening according to a preset percentage.

[0089] Specifically, when the target heat exchange equipment is undersupplied with heat, it can be said that the actual heating power of the target heat exchange equipment is less than the heating demand. At this time, the opening valve corresponding to the target heat exchange equipment is controlled to reduce the opening according to the preset percentage to increase the heat output so that the actual heating power of the target heat exchange equipment reaches the heating demand. In this way, the heating status of the target heat exchange equipment can be monitored in real time, and its heating power can be adjusted according to the heating demand, which can not only avoid energy waste caused by excessive heat supply, but also improve the stability and reliability of the heating system. At the same time, by utilizing the heat storage capacity of the target heat exchange equipment, the energy utilization efficiency can be further improved and the heating cost can be reduced. When the target heat exchange equipment is not undersupplied with heat, it can be said that the actual heating power of the target heat exchange equipment is equal to the heating demand, and the opening valve corresponding to the target heat exchange equipment is not controlled at this time.

[0090] S309, after completing the opening valve adjustment action, the heating system is balanced and regulated throughout the network.

[0091] After completing the dynamic regulation of heat storage and release, balanced regulation of the heating system can ensure the reasonable distribution of heat in the entire network, stabilize the heating quality, and reduce energy waste.

[0092] In some embodiments of the present invention, after controlling the opening valve corresponding to the target heat exchange device to increase the opening according to a preset percentage, the method further includes: determining the mixed water flow rate after the hot water in the shunt pipe and the cold water in the return branch are mixed according to the first flow rate of the hot water in the water supply branch, the second flow rate of the hot water in the shunt pipe, the first temperature of the hot water in the water supply branch, the second temperature of the cold water in the return branch, and the third temperature after the hot water in the shunt pipe and the cold water in the return branch are mixed; determining the total mixed water temperature of the main return water path according to the mixed water flow rate and the total mixed water flow rate of the main return water path; comparing the total mixed water temperature with the preset total mixed water temperature; in response to the total mixed water temperature being less than the preset total mixed water temperature, determining that the adjustment operation for the opening valve meets the preset constraint condition. Among them, the preset total mixed water temperature and the preset constraint condition can be set according to actual conditions.

[0093] Specifically, after controlling the opening valve corresponding to the target heat exchange equipment to increase its opening according to a preset percentage, the mixed water flow rate after the hot water in the shunt pipe and the cold water in the return branch can be judged by the first flow rate of the hot water in the water supply branch and the second flow rate of the hot water in the shunt pipe detected by the first flow sensor and the second flow sensor, and the first temperature of the hot water in the water supply branch, the second temperature of the cold water in the return branch, and the third temperature after the hot water in the shunt pipe and the cold water in the return branch are mixed, that is, the mixed water flow rate = the cold water flow rate in the return branch * (third temperature - second temperature) / (first temperature - third temperature), and then the total mixed water temperature of the main return water channel is determined according to the mixed water flow rate and the total mixed water flow rate of the main return water channel, that is, the total mixed water temperature of the main return water channel = [first temperature * mixed water flow rate + total mixed water temperature of the main return water channel * (total mixed water flow rate of the main return water channel - mixed water flow rate)] / total mixed water flow rate of the main return water channel. After obtaining the total mixed water temperature, the total mixed water temperature is compared with the preset total mixed water temperature to determine whether the total mixed water temperature is less than the preset total mixed water temperature. When the total mixed water temperature is less than the preset total mixed water temperature, it can be said that the total mixed water temperature meets the preset total mixed water temperature and heat demand constraints. At this time, it is determined that the adjustment operation of the opening valve meets the preset constraints.

[0094] In some embodiments of the present invention, verifying whether the target heat exchange device has the heat storage capacity includes: comparing the third temperature after the hot water in the shunt pipeline and the cold water in the return branch are mixed with the preset return water temperature threshold; in response to the third temperature being less than the preset return water temperature threshold, determining that the target heat exchange device has the heat storage capacity; wherein the shunt pipeline is not empty. The preset return water temperature threshold can be set according to actual conditions.

[0095] Specifically, after the heat storage and release dynamic control system has been running for a period of time, the hot water flow in the shunt pipeline (obtained by the second flow sensor) and the third temperature after mixing (obtained by the third temperature sensor) are observed and recorded, wherein the second flow sensor is arranged on the shunt pipeline. The third temperature after mixing the hot water in the shunt pipeline and the cold water in the return branch is compared with the preset return water temperature threshold to determine whether the third temperature is less than the preset return water temperature threshold. When the third temperature is less than the preset return water temperature threshold, it can be considered that the target heat exchange equipment has heat storage capacity because it can store excess heat in the system for emergency use. When the third temperature is not less than the preset return water temperature threshold, it may be necessary to further investigate the cause, such as checking the working efficiency of the heat exchange equipment, the temperature control of the water supply branch, etc. After confirming that there is no fault or abnormality, it can be considered that the target heat exchange equipment does not have significant heat storage capacity under the current conditions.

[0096] As a specific embodiment, the third temperature after the hot water in the bypass pipeline and the cold water in the return branch are mixed is less than the upper limit of the return water temperature (such as 55°C) minus 2°C, and it is determined that the target heat exchange equipment has heat storage capacity.

[0097] In some embodiments of the present invention, the method further includes: determining whether the actual heating power of a single target heat exchange device is greater than the heating demand of the single target heat exchange device, and whether the actual heating power of all target heat exchange devices is greater than the heating demand of all target heat exchange devices in a first preset ratio; in response to the actual heating power of a single target heat exchange device being greater than the heating demand of the single target heat exchange device and the actual heating power of all target heat exchange devices being greater than the heating demand of all target heat exchange devices in a first preset ratio, determining that the target heat exchange device has an oversupply of heat. The first preset ratio can be set according to actual conditions.

[0098] Specifically, after obtaining the actual heating power of each target heat exchanger, first determine whether the actual heating power of a single target heat exchanger is greater than the heating demand of a single target heat exchanger. In the same way, determine whether the actual heating power of all target heat exchangers is greater than the heating demand of all target heat exchangers in the first preset ratio. When the actual heating power of a single target heat exchanger is greater than the heating demand of a single target heat exchanger and the actual heating power of all target heat exchangers is greater than the heating demand of all target heat exchangers in the first preset ratio, it can be determined that the target heat exchanger has an oversupply of heat. By increasing the opening of the opening valve, more hot water can be allowed to flow back to the heat source through the shunt pipeline, thereby reducing the heating power of the target heat exchanger. At the same time, the heat storage capacity of the heat exchanger can be used to store excess heat for emergency use. In this way, the heating status of the target heat exchanger can be monitored in real time, and its heating power can be adjusted according to actual needs, which can not only avoid energy waste caused by oversupply of heat, but also improve the stability and reliability of the system. At the same time, by using the heat storage capacity of the heat exchanger, energy utilization efficiency can be further improved and heating costs can be reduced.

[0099] As a specific embodiment, if the actual heating power of a single target heat exchanger is greater than 100% of the heating demand of the single target heat exchanger, and the actual heating power of all target heat exchangers is greater than 105% of the heating demand of all target heat exchangers, it is determined that the target heat exchanger has an oversupply of heat.

[0100] In some embodiments of the present invention, the method further includes: determining whether the actual heating power of a single target heat exchange device is less than the heating demand of the single target heat exchange device, and whether the actual heating power of all target heat exchange devices is less than the heating demand of all target heat exchange devices in a second preset ratio; in response to the actual heating power of a single target heat exchange device being less than the heating demand of the single target heat exchange device and the actual heating power of all target heat exchange devices being less than the heating demand of all target heat exchange devices in a second preset ratio, determining that the target heat exchange device has a heat shortage. The second preset ratio can be set according to actual conditions.

[0101] Specifically, after obtaining the actual heating power of each target heat exchanger, first determine whether the actual heating power of a single target heat exchanger is less than the heating demand of a single target heat exchanger. In the same way, determine whether the actual heating power of all target heat exchangers is less than the heating demand of all target heat exchangers in the second preset ratio. When the actual heating power of a single target heat exchanger is less than the heating demand of a single target heat exchanger and the actual heating power of all target heat exchangers is less than the heating demand of all target heat exchangers in the second preset ratio, it can be indicated that the actual heating power of the target heat exchanger is insufficient and cannot meet the heating demand. At this time, it is determined that the target heat exchanger has a heat shortage. The heat output can be increased by automatically adjusting the heating power of the relevant heat exchanger. In this way, the heating status of the target heat exchanger can be monitored in real time, and its heating power can be adjusted according to actual demand. This can not only avoid the problem of insufficient heating caused by insufficient heat supply, but also improve the stability and reliability of the system. At the same time, through continuous monitoring and evaluation, the control strategy of the system can be continuously optimized to improve heating efficiency and energy utilization.

[0102] As a specific embodiment, if the actual heating power of a single target heat exchanger is less than 100% of the heating demand of the single target heat exchanger, and the actual heating power of all target heat exchangers is less than 95% of the heating demand of all target heat exchangers, it is determined that the target heat exchanger is undersupplied with heat.

[0103] In some embodiments of the present invention, the above method also includes: determining whether the opening of the opening valve reaches a preset valve opening; in response to the opening of the opening valve reaching the preset valve opening, marking the opening valve as a rest opening valve; wherein, the opening of the rest opening valve is prohibited from being adjusted, and the preset valve opening can be set according to actual conditions.

[0104] Specifically, in order to improve the automation level and energy-saving effect of the heat storage and release dynamic control system, the heat storage and release dynamic control system needs to automatically adjust the opening of the opening valve according to the heating demand. The actual opening value of each opening valve can be monitored in real time through an electromagnetic flow meter, and the opening of the opening valve is compared with the preset valve opening to determine whether the opening of the opening valve reaches the preset valve opening. When the opening of the opening valve reaches the preset valve opening, the opening valve will be automatically marked as a dormant opening valve, which means that the opening of the opening valve will no longer be automatically adjusted by the heat storage and release dynamic control system during subsequent operation, unless the dormant state is manually released. In order to ensure the stability of the dormant opening valve, the heat storage and release dynamic control system will set a locking mechanism internally to prohibit any form of adjustment of the opening of the dormant opening valve. Even if the operator attempts to change the opening of these valves through the heat storage and release dynamic control system interface or manual operation, the heat storage and release dynamic control system will refuse to execute and give a corresponding prompt message. It can not only improve the automation level and energy-saving effect of the heat storage and release dynamic control system, but also avoid the impact of over-adjustment or misoperation on the stability of the heat storage and release dynamic control system. At the same time, through continuous monitoring, the safe and stable operation of the heat storage and release dynamic control system can be ensured.

[0105] As a specific example, Figure 4 As shown, the flow chart of the control method of the heat storage and release dynamic regulation system of the present invention may include the following steps:

[0106] S401, verify whether the target heat exchange device has heat storage capacity. If yes, execute step S402; if no, execute step S410.

[0107] S402, verify whether the target heat exchange device is oversupplied with heat. If yes, execute step S403; if no, execute step S404.

[0108] In this step, it is determined whether the target heat exchange device has an over-supply of heat according to the actual heating power and heating demand of the target heat exchange device.

[0109] S403, increasing the opening of the openable valves from small to large numbers.

[0110] In this step, the opening valve corresponding to the target heat exchange device is controlled to increase the opening according to a preset percentage.

[0111] Specifically, in order to reasonably number the opening valves, the present application can be based on two main principles: one is based on the size of the head pressure loss (if the calculation and measurement capabilities are available), and the other is based on the distance from the heat source (if the calculation and measurement capabilities of the head pressure loss are not available). First, it is necessary to determine whether the heating system has the ability to calculate and measure the head pressure loss. If the head pressure loss calculation and measurement capabilities are available, the valves are numbered according to the head pressure loss. For each opening valve, measure or calculate its head pressure loss, and number them in ascending order according to the size of the loss. The greater the loss, the greater the number. If the calculation and measurement capabilities of the head pressure loss are not available, the valves are numbered according to the distance from the heat source. For each opening valve, measure its distance from the heat source, and number them in ascending order according to the distance. The farther the distance, the greater the number. Finally, the number of each opening valve can be recorded for subsequent management and maintenance.

[0112] For example, suppose there are 5 opening valves, marked as A, B, C, D, and E. Assume that the measured head pressure loss is: A = 10Pa, B = 20Pa, C = 5Pa, D = 30Pa, E = 15Pa. Then the numbering sequence is: C (1), A (2), E (3), B (4), D (5). Assume that the measured distance from the heat source is: A = 50m, B = 100m, C = 75m, D = 200m, E = 150m. Then the numbering sequence is: A (1), C (2), B (3), E (4), D (5). In actual operation, the accuracy of measurement and calculation should be ensured to avoid numbering errors. The numbering system in this application should be easy to understand and use so that the opening valve can be quickly located in an emergency.

[0113] S404, verify whether the target heat exchange equipment is undersupplied with heat. If yes, execute step S405; if no, execute step S406.

[0114] In this step, it is determined whether the target heat exchange device is under-supplied with heat based on the actual heating power and heating demand of the target heat exchange device.

[0115] S405, reducing the opening of the openable valves from the largest to the smallest number.

[0116] In this step, the opening valve corresponding to the target heat exchange device is controlled to reduce the opening according to a preset percentage.

[0117] S406, the supply and demand balance of the heat storage and release dynamic control system, there is neither oversupply of heat nor undersupply of heat.

[0118] In this step, the actual heating power of the target heat exchange equipment is equal to the heating demand.

[0119] S407, judging whether the opening degree of the opening valve reaches the preset valve opening degree. If yes, executing step S408; if no, executing step S409.

[0120] S408, marking the opening valve as a rest opening valve.

[0121] S409, complete the valve opening adjustment.

[0122] S410, the heat storage and release dynamic control system displays the opening valve adjustment result and the opening state of the opening valve.

[0123] Therefore, the present invention breaks through the design concept of the traditional heating system based on fixed heat source and independent energy storage equipment, and innovatively uses the heat medium (water) of the heating network itself as the heat storage medium. By adjusting the thermal potential energy of the supply and return water of the network (such as the average temperature of the supply and return water), heat storage is achieved when "heat source heating > heat exchange station demand" (reference Figure 5 , which is a schematic diagram of the heat storage process temperature and heat source output load according to some embodiments of the present invention), the function of releasing heat when "heat source heat supply < heat exchange station demand" (reference Figure 6 , which is a schematic diagram of the heat release process temperature and the heat source output load according to some embodiments of the present invention), dynamically optimizes the operation mode of the heating system.

[0124] By introducing real-time data acquisition technology and dynamic calculation logic, the key equipment in the pipeline network (such as valves, pumps, etc.) can be automatically adjusted. Through intelligent control algorithms, the system can independently complete the switching of heat storage and heat release according to the changes in heat load demand, greatly reducing the need for manual intervention. When adjusting the operation of the pipeline network, factors such as heating load, heat medium temperature, pipeline pressure, etc. are comprehensively considered, and safety boundary conditions are set to ensure that the system can still operate safely and stably under extreme conditions. By monitoring the deviation between the heat supply and the demand predicted by the climate model, the control strategy is adjusted in time or abnormal nodes are eliminated to ensure the reliability of system data and the accuracy of control. By making full use of the heat storage capacity of the pipeline network itself, the dependence on independent energy storage equipment is reduced, and the cost of system transformation is reduced. During operation, precise control reduces energy waste and carbon emissions, providing an effective solution for low-carbon heating and energy conservation and emission reduction.

[0125] In summary, the control method of the heat storage and release dynamic regulation system according to the embodiment of the present invention includes: determining the heating demand of the target area according to the environmental parameters, building parameters and target demand temperature of the target area, and determining the preset demand range according to the heating demand; obtaining the actual heating power of all heat exchangers, and screening the target heat exchangers from all heat exchangers according to the preset demand range; wherein the actual heating power of the target heat exchangers is within the preset demand range; for each target heat exchanger, verifying whether the target heat exchanger has the heat storage capacity; in response to the target heat exchanger having the heat storage capacity, determining whether the target heat exchanger has the heat oversupply according to the actual heating power and heating demand of the target heat exchanger; in response to the heat oversupply of the target heat exchanger, controlling the opening valve corresponding to the target heat exchanger to increase the opening according to the preset percentage; in response to the heat undersupply of the target heat exchanger, determining whether the target heat exchanger has the heat undersupply according to the actual heating power and heating demand of the target heat exchanger; in response to the heat undersupply of the target heat exchanger, controlling the opening valve corresponding to the target heat exchanger to decrease the opening according to the preset percentage. Therefore, this method realizes heat storage and release of the pipeline network by automatically adjusting the relevant equipment in the pipeline network. It can improve the adjustment efficiency, reduce the error rate, improve the supply and demand balance, improve the heating efficiency, and reduce the system transformation cost while reducing manual intervention.

[0126] It should be noted that the method of the embodiment of the present invention can be performed by a single device, such as a computer or a server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present invention, and the multiple devices will interact with each other to complete the above method.
