Description

Technical Field

[0001] The present application relates to the field of heating technology, and in particular to a temperature control method for a heating system. Background Art

[0002] With the acceleration of global urbanization and the improvement of people's quality of life, the central heating system plays an increasingly important role in modern cities. In order to meet the growing demand for heating and achieve the environmental protection goals of energy conservation and emission reduction, the intelligent management of the heating system has become crucial. Among them, the secondary heating network control algorithm is one of the key technologies to ensure the efficient operation of the heating network.

[0003] Traditional heating management methods often rely on manual experience and lack sophisticated control methods, resulting in uneven heat distribution, high energy consumption, and low user satisfaction. In order to solve these problems, in recent years, the heating system has begun to introduce Internet of Things technology, which realizes real-time monitoring and dynamic adjustment of the heating network by installing smart sensors and control valves in various heat exchange stations, buildings, and units. In this method, the unit return water temperature consistency method is a widely used regulation strategy, which optimizes heat distribution and improves system operation efficiency by adjusting the return water temperature of each unit to a uniform preset value.

[0004] However, the unit return water temperature consistency method has some limitations in practical applications. Due to the slow change of return water temperature, there will be a hysteresis when adjusting the valve, that is, the change of actual return water temperature cannot keep up with the speed of valve adjustment, resulting in a deviation between the valve opening and the expected target, and then there will be problems such as high adjustment hysteresis, high frequency of over-adjustment, and lack of flexibility.

[0005] Therefore, how to manage the heating system more efficiently and flexibly to improve the efficiency and flexibility of temperature regulation has become a problem that needs to be solved urgently. Summary of the invention

[0030] In this embodiment, a temperature control method for a heating system is provided, which is applied to the above-mentioned computer device. Figure 2 : is a flow chart of a temperature control method for a heating system according to an embodiment of the present application, the flow chart comprising the following steps:

[0031] Step S202, obtaining regional return water temperatures at multiple levels in the heating system;

[0032] Step S204, processing the regional return water temperatures of the multiple levels respectively to determine the adjustment temperatures of the multiple levels;

[0033] Step S206, determining the hierarchy priorities of the multiple hierarchies;

[0034] Step S208: regulating the temperature of the heating system based on the adjustment temperatures of the multiple levels and the level priorities of the multiple levels.

[0035] In an embodiment of the present application, by obtaining the regional return water temperatures of multiple levels in the heating system, and processing the regional return water temperatures of these levels respectively, determining the adjustment temperature of each level, and determining the priority of each level, the temperature of the heating system is controlled based on these adjustment temperatures and priorities, thereby achieving hierarchical management and control in the temperature control process, and effectively improving the regulation efficiency and flexibility.

[0036] In an exemplary embodiment, the multiple levels include unit level, building level and community level; the acquisition of regional return water temperatures of multiple levels in the heating system includes: determining the unit return water temperatures corresponding to the multiple units of the unit level based on the unit return water sensor in the heating system, determining the building return water temperatures of the multiple buildings at the building level based on the building return water sensor in the heating system, and determining the community return water temperatures of the multiple communities at the community level based on the community return water sensor in the heating system.

[0037] It should be noted that at the unit level, that is, the most basic unit of the heating system (such as a single room, apartment unit or small commercial space), the return water temperature of each unit can be monitored in real time by installing a unit return temperature sensor on the return water pipeline of each unit. These sensors usually have high accuracy and response speed, and can capture changes in heat demand in the unit in a timely manner. The collected temperature data will be transmitted to the unit control calculation module as the basis for subsequent adjustment of the unit IoT smart valve opening. By comparing the unit return water temperature with the preset unit target temperature, the current thermal energy state of each unit can be calculated to determine whether the valve opening needs to be adjusted and the extent of the adjustment.

[0038] The building level refers to the heating system of a single building or a building. At this level, the building return water temperature of the building needs to be monitored by building return temperature sensors, which are usually installed on the main return water pipeline of the building. The building return water temperature reflects the comprehensive status of the heat load of all units in the building and is the result of unit-level regulation. The acquired building return water temperature data will be used in the building control calculation module to determine the adjustment strategy of the building IoT smart valve. By monitoring the building return water temperature, thermal imbalances inside the building can be discovered in time, such as overheating or overcooling of a unit, so as to make targeted adjustments to maintain the uniform distribution of heat energy in the building.

[0039] The community level covers the heating area consisting of multiple buildings, which may be a residential area, commercial area or mixed-use area. At this level, by installing a community return temperature sensor on the main return water pipe of the community, the return water temperature of the entire community can be monitored in real time. The community return water temperature data will be used in the community control calculation module to guide the adjustment of the community IoT smart valve to achieve thermal energy balance within the community. The community-level adjustment takes into account the differences between different buildings and the hydraulic characteristics of the entire heating system. It can effectively cope with the uneven distribution of heat load in the community and ensure the stability and efficiency of community heating.

[0040] In summary, by deploying return water temperature sensors at the unit, building and community levels, the return water temperature data at each level can be obtained in real time, providing an accurate and timely source of information for subsequent multi-level adjustments. This multi-level data collection and processing mechanism can more comprehensively and accurately reflect the thermal energy status within the heating system, thus providing a solid foundation for achieving efficient and balanced heating management. By monitoring the return water temperature at the unit, building and community levels, not only can local thermal imbalance problems be discovered and resolved in a timely manner, but also the thermal energy distribution of the entire heating network can be optimized, improving the system's operating efficiency and user satisfaction.

[0041] In an exemplary embodiment, the multiple levels include unit level, building level and community level; the acquisition of regional return water temperatures of multiple levels in the heating system includes: determining the unit return water temperatures corresponding to the multiple units of the unit level based on the unit return water sensor in the heating system, determining the building return water temperatures of the multiple buildings at the building level based on the building return water sensor in the heating system, and determining the community return water temperatures of the multiple communities at the community level based on the community return water sensor in the heating system.

[0042] In an exemplary embodiment, the multiple levels include a unit level, a building level and a cell level; the processing of the regional return water temperatures of the multiple levels respectively to determine the adjustment temperatures of the multiple levels includes: for the unit level, determining a target unit return water temperature based on multiple unit return water temperatures of the unit level and the number of units of the unit level; determining an adjustment temperature of each unit of the unit level based on the target unit return water temperature; for the building level, determining a target building return water temperature based on multiple building return water temperatures of the building level and the number of buildings of the building level; determining an adjustment temperature of each building of the building level based on the target building return water temperature; for the cell level, determining a target cell return water temperature based on multiple cell return water temperatures of the cell level and the number of cells of the cell level; determining an adjustment temperature of each cell of the cell level based on the target cell return water temperature.

[0043] It should be noted that at the unit level, the target unit return water temperature is first calculated based on the real-time return water temperature data obtained by the unit return temperature sensor and the number of units. The calculation of the target unit return water temperature may be based on historical data, current heat load, climate conditions, user needs and other factors, and is obtained through mathematical models or algorithms (such as average, weighted average or other statistical methods). After obtaining the target unit return water temperature, the unit return water temperature of each unit is compared with the target unit return water temperature, and the adjustment temperature of each unit is determined based on the deviation value. The calculation of the adjustment temperature involves adjusting the opening of the heating valve so that the unit return water temperature is as close to the target temperature as possible. This process can be implemented using a proportional-integral-differential (PID) control algorithm or other control strategies.

[0044] At the building level, the target building return water temperature is determined based on the return water temperature data obtained by the building return temperature sensor and the number of buildings. The setting of the target building return water temperature should take into account the average demand of all units in the building and the possible heat load differences between buildings. Then, the building return water temperature of each building is compared with the target building return water temperature to calculate the adjusted temperature of each building. The determination of the adjusted temperature is also based on control theory, and the opening of the building IoT smart valve is adjusted to achieve the approach of the building return water temperature to the target temperature. This process may also need to consider the thermal inertia of the building to avoid instability caused by frequent adjustments.

[0045] At the community level, the target community return water temperature is determined based on the return water temperature data obtained by the community return temperature sensor and the number of buildings in the community. The setting of the target community return water temperature needs to comprehensively consider factors such as the heat demand of all buildings and units in the community, changes in the external environment, and the hydraulic characteristics of the heating network to ensure the balance and stability of the heating supply in the entire community. Then, the community return water temperature of the community is compared with the target community return water temperature to determine the adjusted temperature of the community. Adjustments at the community level may involve the control of the community IoT smart valve or heat exchange station to adjust the overall heat energy distribution in the community to ensure that the community return water temperature reaches or is close to the target value.

[0046] In the above embodiment, by determining the adjustment temperature at the unit, building and community levels, the refined management of the second heating network is achieved. It not only improves the accuracy and efficiency of the adjustment, but also can effectively deal with the complex heat load changes and hydraulic characteristics in the heating system, ensuring the balance of heat energy distribution and the comfort experience of users, which is an important technical progress in the intelligent control of the heating system.

[0047] In an exemplary embodiment, the processing of the regional return water temperatures of the multiple levels respectively to determine the adjustment temperatures of the multiple levels also includes: for any one unit in the unit level, based on the target unit return water temperature and the difference between the unit return water temperature of the targeted unit, determining the adjustment temperature of the targeted unit at the unit level; for any one building in the building level, based on the difference between the target building return water temperature and the building return water temperature of the targeted building, determining the adjustment temperature of the targeted building at the building level; for any one cell in the cell level, based on the difference between the target cell return water temperature and the cell return water temperature of the targeted cell, determining the adjustment temperature of the targeted cell at the cell level.

[0048] It should be noted that for any unit in the unit hierarchy, the difference between the unit return water temperature and the target unit return water temperature will be calculated. This difference reflects the deviation between the current thermal energy state of the unit and the thermal energy state required by the system, and is the basis for determining the adjustment temperature. Based on this difference, determine whether it is necessary to adjust the heating valve opening of the unit, as well as the direction and amplitude of the adjustment. If the unit return water temperature of the unit is lower than the target unit return water temperature, that is, when the unit adjustment temperature is greater than 0, the valve opening is reduced to ensure that the unit return water temperature is close to the target unit return water temperature to achieve a balance between heat supply and demand; if the unit return water temperature of the unit is higher than the target unit return water temperature, that is, when the unit adjustment temperature is less than 0, it means that the unit needs more heat energy and the valve opening will be increased.

[0049] For any building in the building hierarchy, the difference between the building return water temperature and the target building return water temperature is also calculated. This difference reflects the degree of mismatch between the overall thermal energy state of the building and the state required by the system, and is a key indicator for adjusting the building heating strategy. Based on the size and direction of the difference, it will be determined whether it is necessary to adjust the opening of the building IoT smart valve, as well as the specific adjustment plan. When the adjustment temperature at the building level is greater than 0, the valve opening of the building return water valve in the water supply system is controlled to be reduced; when the building return water temperature at the building level is adjusted and the adjustment temperature at the building level is less than 0, the valve opening of the building return water valve in the water supply system is controlled to be increased;

[0050] For any cell in the cell level, the adjustment plan is determined based on the difference between the regional return water temperature of the cell and the target cell return water temperature. The adjusted temperature at the cell level is not only affected by the internal heat demand of the cell, but also by the external environmental conditions and the hydraulic characteristics of the heating network. Therefore, the adjustment strategy at the cell level needs to be more comprehensive and flexible, which may include adjusting the opening of the cell IoT smart valve, increasing or decreasing the supply of heat sources, and even adjusting the hydraulic balance of the heating network to ensure that the cell return water temperature reaches the target value and maintains the thermal energy balance of the entire community. When the regional return water temperature at the cell level is adjusted and the adjusted temperature at the cell level is greater than 0, the valve opening of the cell return water valve in the water supply system is controlled to be reduced; when the cell return water temperature at the cell level is adjusted and the adjusted temperature at the cell level is less than 0, the valve opening of the cell return water valve in the water supply system is controlled to be increased.

[0051] In the above embodiment, the difference in return water temperature is calculated at the three levels of unit, building and community to determine the adjustment temperature of each specific level, thereby realizing refined thermal balance control of the second heating network. This method not only improves the accuracy and response speed of regulation, but also can effectively cope with the complex and changeable heat load requirements in the system, ensures the balance of heat energy distribution and the comfort experience of users, and is an important progress in the intelligent management of heating systems.

[0052] In an exemplary embodiment, the multiple levels include unit level, building level and community level; the temperature of the heating system is regulated based on the adjustment temperatures of the multiple levels and the level priorities of the multiple levels, including: based on the level priorities of the multiple levels, the unit return water temperature of the unit level, the building return water temperature of the building level and the community return water temperature of the community level are adjusted in sequence according to the adjustment temperatures, wherein the adjustment of the unit return water temperature of the unit level takes precedence over the adjustment of the building return water temperature of the building level, and the adjustment of the building return water temperature of the building level takes precedence over the adjustment of the community return water temperature of the community level.

[0053] First, clarify the priority of each level. In the management and control of the secondary heating network, the control at the unit level is the most directly oriented to user needs. Therefore, the unit return water temperature adjustment at the unit level usually has the highest priority. The control at the building level is to further balance the thermal distribution inside the building on the basis of meeting the unit level needs. Therefore, the building return water temperature adjustment at the building level has the next level of priority. Finally, the control at the community level is to adjust the heat energy distribution of the entire community on the premise of ensuring that the unit and building level needs are met to achieve thermal balance within the community. Therefore, the community return water temperature adjustment at the community level has the lowest priority.

[0054] It should be noted that the opening of the unit IoT smart valve in the unit level is adjusted according to the difference between the target unit return water temperature and the unit return water temperature. This adjustment has the highest priority, ensuring that each unit can be accurately regulated to maintain its return water temperature close to the target value and meet the user's thermal comfort needs.

[0055] After the unit-level adjustment is basically completed, the opening of the building IoT smart valve at the building level is adjusted according to the difference between the target building return water temperature and the building return water temperature. This level of adjustment takes precedence over the community level, but is inferior to the unit level. It aims to balance the heat energy distribution of all units inside the building and ensure the overall thermal balance of the building. Through the adjustment at the building level, the thermal imbalance inside the building can be effectively reduced and the heating efficiency can be improved.

[0056] Finally, based on the difference between the return water temperature of the target community and the return water temperature of the community, the heat distribution at the community level is adjusted. This level of adjustment has the lowest priority, but after the unit and building level adjustments are completed, it is crucial to optimize the overall thermal balance of the system. The community-level adjustment may include the control of the community IoT smart valve and the adjustment of the hydraulic balance of the heating network to ensure the balance and stability of heat distribution throughout the community.

[0057] During the adjustment process, attention should be paid to the mutual influence between the various levels. For example, adjustments at the unit level may affect the thermal balance at the building level, while adjustments at the building level will also affect the overall thermal energy distribution at the community level. Therefore, when implementing the adjustment strategy, a coordination mechanism should be adopted to ensure that adjustments at high-priority levels do not cause irreversible negative effects on low-priority levels. This coordination mechanism may include dynamic optimization algorithms, such as predictive control, adaptive control, or intelligent optimization algorithms, to adjust the control parameters of each level in real time to achieve efficient and stable operation of the entire heating system.

[0058] In an exemplary embodiment, the unit return water temperature at the unit level, the building return water temperature at the building level, and the community return water temperature at the community level are adjusted in sequence according to the adjustment temperature, including: when the unit return water temperature at the unit level is adjusted and the adjustment temperature at the unit level is greater than 0, controlling to reduce the valve opening of the unit return water valve in the water supply system; when the unit return water temperature at the unit level is adjusted and the adjustment temperature at the unit level is less than 0, controlling to increase the valve opening of the unit return water valve in the water supply system; when the building return water temperature at the building level is adjusted and the building return water temperature at the building level is adjusted, When the adjustment temperature of the layer is greater than 0, the valve opening of the building return valve in the water supply system is controlled to be reduced; when the building return water temperature of the building layer is adjusted and the adjustment temperature of the building layer is less than 0, the valve opening of the building return water valve in the water supply system is controlled to be increased; when the community return water temperature of the community level is adjusted and the adjustment temperature of the community level is greater than 0, the valve opening of the community return water valve in the water supply system is controlled to be reduced; when the community return water temperature of the community level is adjusted and the adjustment temperature of the community level is less than 0, the valve opening of the community return water valve in the water supply system is controlled to be increased.

[0059] In order to better understand the process of the temperature control method of the above-mentioned heating system, the temperature control method of the above-mentioned heating system is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0060] This application proposes a temperature control algorithm for a heating system. On the basis of calculating and participating in the regulation of the unit return water temperature, it also collects the building return water temperature and the community return water temperature, and realizes the calculation and participation in the regulation of the building return water temperature and the community return water temperature, thereby realizing hierarchical management and control and improving the regulation efficiency and flexibility.

For a typical heating network control system including community 1 and community 2, the following facilities are installed and constructed, including unit temperature return sensor 3, unit IoT smart valve 4, building temperature return sensor 5, building IoT smart valve 6, community temperature return sensor 7, community IoT smart valve 8, heat exchange station 9, and relevant algorithms are developed to form unit control calculation module 10, building control calculation module 11, and community control calculation module 12, so as to realize the hierarchical control calculation of valves.

[0062] During the actual pipeline adjustment process, after the adjustment of the IoT smart valves 4 of each unit, the hydraulic characteristics of each unit in the same building are basically fixed. At this time, when the IoT smart valves 6 of the building are adjusted, the influence on the coupling characteristics between the units in the same building can be basically ignored; similarly, after the adjustment of the IoT smart valves 6 of each building, the hydraulic characteristics of each building in the same community are basically fixed. At this time, when the IoT smart valves 8 of the community are adjusted, the influence on the coupling characteristics of each building in the same community can be basically ignored.

[0063] Based on the above principles, the control process of the temperature control method of the heating system of the present application is as follows:

[0064] First, the unit control calculation module 10 performs a balance adjustment on the unit IoT smart valve 4 under each building. Taking the building as a unit, the target unit return water temperature of each unit under the same building is determined by the temperature parameter collected by the unit return water sensor 3 of the corresponding unit. The specific calculation formula is expressed as:

[0065]

[0066] in, is the target unit return water temperature of each unit in the i-th building, T u is the unit return water temperature of each unit under the i-th building, measured by the unit return water sensor 3.

[0067] The opening instruction of each unit IoT smart valve 4 is determined by the difference between the unit return water temperature of the unit and the target unit return water temperature, that is:

[0068]

[0069] Thereby achieving the regulation of the unit IoT smart valve 4.

[0070] Then the building control calculation module 11 performs the balance adjustment of the building IoT smart valve 6 of each building. Taking the community as the unit, the target building return water temperature of each building in each community is determined by the temperature parameter collected by the building return water sensor 5 of the corresponding building. The specific calculation formula is expressed as:

[0071]

[0072] in, is the target building return water temperature, T b is the building return water temperature of each building, measured by the building return water sensor 5.

[0073] The opening instruction of each building IoT smart valve 6 is determined by the difference between the building return water temperature of the building and the target building return water temperature, that is:

[0074]

[0075] Thereby realizing the regulation of the building Internet of Things smart valve 6.

[0076] Then, the cell control calculation module 12 performs a balance adjustment on the cell IoT smart valve 8 of each cell. The target cell return water temperature of all cells is determined by the temperature parameters collected by the cell return temperature sensors 7 of all cells. The specific calculation formula is:

[0077]

[0078] in, is the return water temperature of the target cell, T r is the return water temperature of the community, measured by the community return water sensor 7.

[0079] The opening instruction of each community IoT smart valve 8 is determined by the difference between the community return water temperature of the community and the target community return water temperature, that is:

[0080]

[0081] Thereby, the adjustment of the community IoT smart valve 8 is realized. After the above adjustment process is completed, when a large adjustment is needed later, it can be quickly adjusted for buildings and communities to achieve rapid adjustment.
