Description

Technical Field

[0001] The present application relates to the field of water supply technology, and in particular to a circulating water pump energy efficiency optimization control method and system. Background Art

[0002] A circulating water pump is a water pump used in a circulation system. Its main function is to push water to circulate in the system. In heating systems, cooling systems or industrial water circulation systems, circulating water pumps play an important role in maintaining water circulation.

[0003] In heating systems, circulating water pumps are usually used to circulate hot water to ensure that hot water can be evenly transferred to each radiator or floor heating pipe, thereby achieving indoor heating. In cooling systems, circulating water pumps are used to ensure the circulation of coolant in the equipment to help the equipment dissipate heat. In industrial water circulation systems, circulating water pumps are used to promote the flow of water in various process flows.

[0004] The working principle of a circulating water pump is usually to drive the impeller to rotate through a motor, thereby generating suction and pressure to enable water to flow through the system. Depending on the needs of the system, the circulating water pump can be equipped with different control devices, such as a frequency converter, to achieve precise regulation of water flow and further improve energy efficiency. The energy efficiency of a circulating water pump mainly refers to the efficiency of energy utilization during the working process of the circulating water pump, which reflects the ratio of the energy consumed by the circulating pump under specific working conditions to the liquid power it outputs.

[0005] In the traditional technology, when optimizing the energy efficiency of the circulating water pump, the comparative document CN114790980A discloses a water pump intelligent management system based on energy efficiency control, including: a water pump module, an input power detection module and a timing monitoring module. The present invention collects energy efficiency data corresponding to a flow data at regular intervals, and compares it with the average energy efficiency corresponding to the working time of the water pump unit at that time, thereby eliminating the influence of the working time of the water pump unit, and obtaining the influence of the flow on the energy efficiency of the water pump unit during a period of work. Then, the flow of each water pump unit is adjusted according to the flow demand and the influence of the flow on the energy efficiency of the water pump unit, so that as many water pump units as possible can operate under good energy efficiency conditions.

[0006] However, the above process only involves controlling the energy efficiency of a single circulating water pump. In more complex scenarios, for example, when multiple water pumps are involved in supplying water, there is still no effective solution for improving the overall water supply energy efficiency.

[0083] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0084] In an exemplary embodiment, Figure 1 As shown, a circulating water pump energy efficiency optimization control method is provided, comprising:

[0085] Step 101, obtaining water supply demand information, the water supply demand information including the water supply starting point location, the water supply end point location and the water supply flow information.

[0086] Among them, it is necessary to clarify the demand for water supply, including the starting point of water supply (the starting point of water supply), the destination of water (the end point of water supply), and the amount of water to be supplied (water supply flow information). This information is the basis for planning water supply.

[0087] Step 102, obtaining building structure information between the water supply starting point and the water supply end point.

[0088] Understanding the building structure between the water supply starting point and end point, including floor heights, wall locations, existing pipe layout, etc., is critical to planning the water supply route.

[0089] Step 103, determining the total lift information according to the height difference between the water supply starting point and the water supply end point.

[0090] The total head required is calculated based on the height difference between the starting point and the end point of the water supply. The head refers to the height to which the pump can lift water and is an important parameter for selecting a water pump.

[0091] Step 104: Determine at least one water pump combination according to the water pump parameter information, total head information and water supply flow information of each circulating water pump.

[0092] Wherein, the water pump assembly includes at least one circulating water pump.

[0093] Specifically, the pump parameters (such as head, flow rate, etc.) of multiple circulating water pumps, the required total head, and the water supply flow rate information are considered to select a suitable pump combination. These pumps will work together to meet the water supply demand.

[0094] Step 105, using the building structure information as a constraint condition, determine the candidate water supply paths corresponding to each water pump combination.

[0095] Possible water supply paths are planned for each pump combination, taking into account the constraints of building structure information (such as walls, floors, etc.). These paths need to avoid obstacles and ensure that they can connect to all pumps.

[0096] Step 106, for any candidate water supply path, determine the total water supply energy efficiency of the candidate water supply path according to the pipeline information of the candidate water supply path and the working efficiency of each circulating water pump in the candidate water supply path.

[0097] For each candidate water supply path, the total water supply energy efficiency of the path is calculated based on its pipeline information (such as pipeline length, diameter, material, etc.) and the working efficiency of the water pump in the path (such as power, efficiency, etc.). This energy efficiency index can reflect the efficiency and economy of water supply.

[0098] Step 107: determine the candidate water supply path with the highest total water supply energy efficiency as the target water supply path.

[0099] Compare the total water supply energy efficiency of all candidate water supply paths, and select the path with the highest energy efficiency as the target water supply path. This path will be the optimal water supply solution that can maximize energy efficiency and reduce costs while meeting water supply needs.

[0100] The above-mentioned circulating water pump energy efficiency optimization control method, this application understands the building structure between the water supply starting point and the end point, including information such as floors, room layouts, pipe wells, etc., which helps to plan the most suitable water supply path. For each candidate water supply path, the total water supply energy efficiency of the path is comprehensively evaluated based on its pipeline information (such as pipeline length, diameter, material, etc.) and the working efficiency of each circulating water pump in the path. Among all candidate water supply paths, the path with the highest total water supply energy efficiency is selected as the target water supply path. This path will serve as the optimal solution for actual water supply. Through this method, not only the energy efficiency of a single water pump is optimized, but also the energy efficiency of multiple water pumps when supplying water is improved as a whole. This helps to reduce the operating cost of water supply and improve energy efficiency, thereby achieving a more environmentally friendly and economical water supply method.

[0101] In one embodiment, Figure 2 As shown in the figure, taking the building structure information as the constraint condition, the candidate water supply paths corresponding to each pump combination are determined, including:

[0102] Step 201: for any building object, determine a path avoidance area and a path passable area in the building object.

[0103] Among them, the water supply route needs to avoid the path avoidance area.

[0104] Specifically, first, collect detailed design drawings, floor plans, stereograms or other relevant building information of the building object. Analyze these drawings and information to identify the structural features inside the building, including important structures such as load-bearing walls, columns, stairs, elevator shafts, and pipe shafts. Areas such as load-bearing walls, large equipment rooms, electrical rooms, and important pipe and cable channels are usually not suitable or allowed to be crossed due to structural or safety reasons. These areas should be marked as path avoidance areas. In addition to the path avoidance areas, other spaces in the building, such as corridors, rooms, stairwells, etc., can theoretically be used as potential passage areas for water supply paths. Clearly mark the path avoidance areas and path passable areas on the architectural drawings. Create a detailed record listing the attributes of each area, such as size, location, load-bearing capacity, etc., to facilitate subsequent water supply path planning and design.

[0105] Specifically, Figure 3 As shown, the building structure information includes the building plan, building stereogram and building section of each building object; and the path avoidance area and the path passable area in the building object are determined.

[0106] Among them, the water supply route needs to avoid the path avoidance area, including:

[0107] Step 301, determining the floor height information, room layout information, corridor information, staircase information and elevator shaft information of the building object according to the building plan, building stereogram and building section view corresponding to the building object.

[0108] Floor height information: The height of each floor and the total height of the entire building can be clearly seen from the section view and stereogram. Room layout information: The floor plan details the location, size, shape of each room, and the relationship between them. Corridor information: The corridor is an important passage space inside the building. Its location, width, and direction can be obtained from the floor plan. Staircase information: Stairs are vertical traffic spaces connecting different floors. Information such as their location, width, and number of levels can be obtained from the section view and floor plan. Elevator shaft information: The location and size of the elevator shaft are also important for path planning. This information can be extracted from the section view and floor plan.

[0109] Step 302, determining the corresponding building avoidance area and building passable area within the building object based on the floor height information, room layout information, corridor information, staircase information and elevator shaft information of the building object.

[0110] Building avoidance area: This usually includes load-bearing walls, large equipment rooms, electrical rooms, stairwells (considering safety and space occupancy), elevator shafts and other important and inaccessible areas. Building passable area: Other spaces outside the avoidance area, such as corridors, ordinary rooms, etc., may become potential passable areas for water supply paths. However, factors such as size and load-bearing capacity need to be further evaluated.

[0111] Step 303, determining the path avoidance area and the path passable area between the water supply starting point and the water supply end point according to the building avoidance area and the building passable area in each building object.

[0112] Among them, load-bearing walls, electrical pipelines and preset types of key equipment are arranged in the building avoidance area.

[0113] Specifically, path avoidance area: This refers to the area that the water supply path must not cross. It includes all important building avoidance areas, especially those located between the starting point and the end point of the water supply. Path passable area: After avoiding all path avoidance areas, the water supply path can choose to cross the building passable area. These areas should ensure the safe laying of water pipes, while taking into account the convenience of maintenance and repair.

[0114] Step 202: Determine the installation position of each circulating water pump in the path passable area according to the water pump parameter information of each circulating water pump in the water pump combination.

[0115] Pump parameter analysis: First, analyze the pump parameter information of each circulating water pump in detail, including but not limited to the pump head, flow rate, power, size (length, width, height) and weight. Understand the optimal working conditions of each pump, such as the required water source conditions, the location and direction of the inlet and outlet, etc.

[0116] Assessment of accessible areas: Review the accessible areas identified in step 201 and analyze factors such as size, load-bearing capacity, ventilation conditions, and proximity to power sources. Pay special attention to areas that are large enough and structurally stable, as these areas are more suitable for installing circulating water pumps.

[0117] Installation location selection: Based on the evaluation results of the pump parameters and the accessible area, several possible installation locations are initially selected. Consider the location of the pump inlet and outlet to ensure that the water pipe can be easily and efficiently connected to the pump, while reducing unnecessary elbows and transitions. Ensure that the installation location is convenient for future maintenance and repair, and leave enough operating space. Safety and stability considerations:

[0118] Verify that the load-bearing capacity of the ground or floor at the selected location meets the weight requirements of the pump and its accessories. Ensure that the installation location is away from flammable and explosive items and has good ventilation conditions to prevent safety problems caused by the heat generated by the operation of the pump.

[0119] Furthermore, the water pump parameter information includes water pump head information; Figure 4 As shown, the method also includes:

[0120] Step 401, for any building object, determine the installation floor of each circulating water pump in the building object according to the pump head information of each circulating water pump.

[0121] First, query the pump head information of each circulating water pump. The head refers to the height to which the pump can lift water, which determines how high the pump can pump water. Based on the head of each pump, you can estimate the highest floor that each pump can theoretically supply water to. Analyze the total number of floors of the building object and the height of each floor to understand the water pressure requirements and water supply difficulty of each floor. Combined with the pump head information, preliminarily determine which floors can be supplied by which pumps. Based on the pump head and the requirements of the building floors, select one or more suitable installation floors for each circulating water pump. When selecting the installation floor, you also need to consider factors such as the actual water demand of the floor, the energy efficiency of the pump, and the layout of the pipe network.

[0122] Step 402: for any circulating water pump, determine the building avoidance area and the building passable area in the corresponding installation floor.

[0123] Floor plan analysis: Get the floor plan of the selected installation floor and analyze the room layout, corridors, stairs, elevator shafts and other structures in detail. Identify areas that need to be avoided, such as load-bearing walls, large equipment rooms, pipe shafts, etc. Building avoidance area determination: Mark the above areas that need to be avoided as building avoidance areas, which are not suitable or allowed to install water pumps or lay water pipes.

[0124] Pay attention to key areas such as electrical rooms and control rooms to ensure that the installation of water supply will not cause interference or safety hazards to these areas. In addition to the building avoidance area, other spaces within the floor, such as corridors, ordinary rooms, etc., can be regarded as the building's passable areas. In these passable areas, further screen out areas suitable for installing water pumps and laying water pipes, taking into account factors such as space size, load-bearing capacity, and ventilation conditions.

[0125] Step 203, when the installation positions of the circulating water pumps are determined, the connection lines between the circulating water pumps are determined with the shortest length of the water supply path as a constraint condition, and a candidate water supply path corresponding to the water pump combination is obtained.

[0126] In this scenario, the starting point can be the water source or the main water supply pipeline, and the end point is the final location where water is needed, which may be a certain area of ​​the building or a specific water point. For a circulating water pump, the starting point and end point may be the water inlet and outlet of the water pump, or the points where water pumps need to be connected.

[0127] List all possible connecting routes: Based on the determined water pump installation locations, list all possible connecting routes from one water pump to another water pump. These routes should avoid the path avoidance area determined in step 201 and only cross the path passable area.

[0128] Calculate the path length of each connection route: For each possible connection route, calculate its total length. This can be obtained by measuring or estimating the sum of the distances of each segment on the route. The calculation of path length should be based on the actual building layout and pump location to ensure accuracy.

[0129] Select the connection route with the shortest path length: compare the path lengths of all possible connection routes and select one or several routes with the shortest length. If there are multiple routes with the same length and they are all the shortest, further selection can be made based on other factors (such as construction difficulty, material cost, etc.). Determine the candidate water supply path: determine the selected shortest connection route as the candidate water supply path. This path will connect all circulating water pumps and meet the requirement of the shortest path length.

[0130] In an exemplary embodiment, when determining the installation position of each circulating water pump, the path length of the water supply path is minimized and a constraint condition is used to determine the connecting routes between the circulating water pumps to obtain a candidate water supply path corresponding to the water pump combination, including: when determining the installation position of each circulating water pump, the path length of the water supply path is minimized and a minimum number of pipe bend connectors used in the candidate water supply path are minimized and a constraint condition is used to determine the connecting routes between the circulating water pumps to obtain a candidate water supply path corresponding to the water pump combination.

[0131] When calculating the length of the water supply path, if the building plan is in the form of a CAD drawing or other accurate electronic drawing, you can use software tools to directly measure the length of the path. Many CAD software provide measurement tools that can directly determine the length of a line segment or curve.

[0132] If there is no electronic drawing, or manual calculation is required, the following method can be used: Calculation of straight line segment length: For a straight line segment, the Pythagorean theorem can be used to calculate the length. If the projection length of the straight line segment on the two coordinate axes (i.e. the horizontal distance and the vertical distance) is known, the length L of the straight line segment can be calculated by the following formula:

[0133] (L=\sqrt{x^2+y^2})

[0134] Here, x is the horizontal distance and y is the vertical distance.

[0135] Estimation of curve segment length: For curve segments, if the curve is complex, an approximate method can be used. A common method is to divide the curve into multiple small segments, each of which is approximated as a straight line segment, and then calculate the length of these straight line segments separately, and finally add them up to get the total length of the curve segment.

[0136] Regarding the number of turning connectors, this is usually determined based on design requirements and actual site conditions. When designing the water supply path, the number of turning connectors should be minimized to reduce water flow resistance, reduce the risk of water leakage, and improve efficiency.

[0137] Specifically, Figure 5 As shown, when the installation position of each circulating water pump is determined, the connection lines between the circulating water pumps are determined with the shortest path length of the water supply path and the least number of pipe turning connectors used in the candidate water supply path as constraints, and the candidate water supply path corresponding to the water pump combination is obtained, including:

[0138] Step 501, according to the installation position of each circulating water pump, the shortest path algorithm is used to determine each water supply path to be selected.

[0139] In this step, the shortest path algorithm (such as Dijkstra algorithm, Floyd algorithm, etc.) is used to determine the shortest connection between the circulating water pumps. These algorithms will find the shortest path connecting all the pumps based on the installation location of the pumps and the walkable paths in the building. The goal of this step is to ensure that the path that water takes during transportation is as short as possible, thereby reducing energy loss and improving efficiency.

[0140] Step 502, determining the number of pipe bend connectors in each water supply path to be selected.

[0141] After determining the shortest path, this step will count the number of pipe turns in each path. Turns increase the resistance of water flow and may become potential leaks, so their number needs to be minimized. By counting the number of turns in each path, the quality of the path can be further evaluated.

[0142] Step 503: for any water supply path to be selected, the installation position of each circulating water pump in the water supply path to be selected is adjusted within a preset error range so that the number of pipe turning connectors in the water supply path to be selected reaches a minimum value.

[0143] This step is to fine-tune the installation position of the water pump under certain conditions. For each selected water supply path, if it is found that adjusting the installation position of a water pump within the preset error range can reduce the number of turning connectors, then such an adjustment will be made. This adjustment is based on a deep understanding of the building layout and water pump performance to ensure that the water supply path is further optimized through fine-tuning without affecting the overall water supply efficiency.

[0144] In an exemplary embodiment, Figure 6 As shown, the pipeline information includes the pipeline length and the inner diameter of the pipeline; for any candidate water supply path, the total water supply energy efficiency of the candidate water supply path is determined according to the pipeline information of the candidate water supply path and the working efficiency of each circulating water pump in the candidate water supply path, including:

[0145] Step 601, determining pipeline loss energy consumption according to pipeline information of the candidate water supply path.

[0146] The energy loss in pipelines is mainly due to the energy loss caused by friction, elbows, valves, etc. when water flows in the pipeline. These losses can be obtained by calculating the loss along the way and local loss of the fluid. The loss along the way is related to the length of the pipeline, the inner diameter, the fluid velocity and the medium density; while the local loss is related to the local obstructions such as elbows and valves in the pipeline. The specific calculation formula may vary depending on the characteristics, but usually involves fluid mechanics principles such as the Darcy-Weisbach formula or the Hegen-Poiseuille equation.

[0147] Step 602: for any circulating water pump, measure the actual energy consumption of the circulating water pump, and determine the minimum energy consumption of the circulating water pump when the water supply demand information is met.

[0148] The total energy consumption of the circulating water pump is a combination of its actual energy consumption and the minimum energy consumption under the water supply demand. This can be a weighted average, or a value that is dynamically adjusted according to the actual operating conditions and water supply demand. It is important to ensure that this total energy consumption value can truly reflect the energy consumption of the water pump during operation.

[0149] Step 603: Determine the total energy consumption of the circulating water pump according to the actual energy consumption and the minimum energy consumption of the circulating water pump.

[0150] The total energy consumption of the circulating water pump is a combination of its actual energy consumption and the minimum energy consumption under the water supply demand. This can be a weighted average, or a value that is dynamically adjusted according to the actual operating conditions and water supply demand. It is important to ensure that this total energy consumption value can truly reflect the energy consumption of the water pump during operation.

[0151] Step 604: for the candidate water supply path, determine the water supply energy efficiency of the candidate water supply path according to the total energy consumption of each circulating water pump and the pipeline loss energy consumption in the candidate water supply path.

[0152] The final step is to combine the data collected in the previous steps to determine the energy efficiency of the entire water supply path. This usually involves adding the total energy consumption of all circulating water pumps and the energy consumption of pipe losses, and then comparing it to the total water supply. Energy efficiency can be expressed as the energy consumption required per unit of water supply, such as kilowatt-hours per cubic meter (kWh / m 3 ). By comparing the energy efficiency values ​​of different candidate water supply paths, the most energy-saving and efficient water supply solution can be selected.

[0153] In an exemplary embodiment, at least one water pump combination is determined based on the water pump parameter information, total head information and water supply flow information of each circulation water pump, including:

[0154] The total water supply flow information between the water supply starting point and the water supply end point and the water pump parameter information of each available water pump are used to select at least one to-be-selected parallel water pump group from each available water pump.

[0155] First, consider the total water supply flow demand between the water supply starting point and the water supply end point. Next, analyze the pump parameter information of each available water pump, especially the flow parameter. According to the total water supply flow demand, select a pump combination that can work in parallel to meet this flow demand from the available water pumps. The characteristic of the parallel water pump group is that the flow of each water pump can be superimposed, so when selecting, ensure that the total flow of the parallel combination can meet or exceed the water supply demand.

[0156] The total water supply head between the water supply starting point and the water supply end point and the water pump parameter information of each available water pump are used to select at least one to-be-selected series water pump group from each available water pump.

[0157] Next, consider the total water supply head requirement between the water supply starting point and the water supply end point. Analyze the head parameters of each available water pump. According to the total water supply head requirement, select a pump combination from the available water pumps that can work in series to meet this head requirement. The characteristic of the series pump group is that the heads of each pump can be superimposed, so when selecting, ensure that the total head of the series combination can meet the water supply demand.

[0158] Each to-be-selected series water pump group and the to-be-selected parallel water pump group are combined to obtain at least one to-be-selected water pump combination.

[0159] Combine the previously selected parallel pump groups and series pump groups. This combination is designed to meet the flow and head requirements at the same time, ensuring that the water supply can work efficiently and stably. In this way, multiple pump combinations can be constructed, each with different characteristics and performance.
