Description
Technical Field
[0001] This invention relates to the field of heating system technology, and in particular to a multi-energy heating system, control method, electronic device, and readable storage medium. Background Technology
[0002] With rising energy costs and increasing emphasis on energy conservation and environmental protection, the demand for efficient energy use is growing. The implementation of peak-valley electricity pricing policies provides users with opportunities to reduce electricity costs. By guiding users to use electricity during off-peak hours through price signals, it can effectively alleviate power supply pressure on the grid during peak periods and promote energy conservation and sustainable use.
[0003] Currently, heating systems mostly use electric water heaters, solar water heaters, or heat pump water heaters to provide hot water. When used alone, these water heaters often cannot fully utilize the advantages of peak-valley electricity pricing, which not only fails to optimize power allocation but also increases heating costs.
[0004] In view of this, the present invention is hereby proposed. Summary of the Invention
[0005] The technical problem to be solved by this invention is to overcome at least some of the shortcomings of the prior art and provide a control method for a multi-energy heating system. During off-peak electricity hours and when there is sufficient sunlight, the solar heating module is activated first. When the solar heating capacity is insufficient, the system is intelligently switched to a heat pump heating module or an electric heating module for auxiliary heating. This method optimizes power configuration and reduces heating costs while ensuring the stability and efficiency of hot water supply.
[0006] To solve the above-mentioned technical problems, a first aspect of the present invention is to provide a control method for a multi-energy heating system, comprising:
[0007] Once it is determined that the current time falls within the local off-peak electricity price period, the solar thermal conversion efficiency at that time can be obtained.
[0008] When it is determined that the solar thermal conversion efficiency of the current time exceeds the preset conversion efficiency, the solar heating module is activated.
[0009] During the operation of the solar heating module, the current water temperature rise rate is acquired; and
[0010] The heat pump heating module and the electric heating module are selectively activated based on the relationship between the current water temperature rise rate and the preset heating rise rate.
[0011] In some implementations, the step of selectively controlling the start-up of the heat pump heating module and the electric heating module based on the relationship between the current water temperature rise rate and the preset heating rise rate includes:
[0012] When it is determined that the current water temperature rise rate during the operation of the solar heating module is lower than the preset heating rise rate, the heat pump heating module is controlled to start and continue to acquire the current water temperature rise rate; or, when it is determined that the current water temperature rise rate during the operation of the solar heating module is higher than or equal to the preset heating rise rate, the heat pump heating module and the electric heating module are controlled to standby.
[0013] If it is determined that the current water temperature rise rate during the operation of the heat pump heating module is still lower than the preset heating rise rate, the electric heating module is controlled to start; or, if it is determined that the current water temperature rise rate during the operation of the heat pump heating module is higher than or equal to the preset heating rise rate, the electric heating module is controlled to standby.
[0014] In some implementations, when it is determined that the solar thermal conversion efficiency at the current time does not exceed the preset conversion efficiency, the heat pump heating module is controlled to start.
[0015] During the operation of the heat pump heating module, the current water temperature rise rate is acquired; and
[0016] The start and stop of the electric heating module are controlled according to the relationship between the current water temperature rise rate and the preset heating rise rate.
[0017] In some implementations, the control method for a multi-energy heating system further includes:
[0018] When it is determined that the current time falls within the local peak electricity price period, the current water temperature is obtained in real time;
[0019] When it is determined that the current water temperature is lower than the minimum insulation temperature, the solar heating module is controlled to start insulation and the current water temperature decrease rate is obtained.
[0020] When it is determined that the current water temperature decrease rate during the heat preservation process of the solar heating module is higher than the preset heat preservation decrease rate, the heat pump heating module is controlled to start the heat preservation mode.
[0021] In some implementations, the control method for a multi-energy heating system further includes:
[0022] When the remaining time of the off-peak electricity price period is determined to be less than a preset time threshold, the current water temperature is obtained;
[0023] When the difference between the current water temperature and the target temperature exceeds a preset difference threshold, the heat pump heating module and the electric heating module are activated until the current water temperature reaches the target temperature.
[0024] In some implementations, the control method for a multi-energy heating system further includes:
[0025] Get the local off-peak and peak electricity price periods.
[0026] In some implementations, the steps of obtaining local off-peak and peak electricity price periods include:
[0027] Send a search request to the server, the search request including the peak-valley time-of-use electricity pricing schedule published by the local power supply department;
[0028] Receive the peak-valley time-of-use electricity price schedule sent by the server, and determine the local off-peak electricity price period and peak electricity price period based on the peak-valley time-of-use electricity price schedule.
[0029] A second aspect of the present invention is to provide a multi-energy heating system, characterized in that it includes a control method for implementing the multi-energy heating system described above.
[0030] A third aspect of the present invention is to provide an electronic device comprising:
[0031] Memory, used to store one or more programs or instructions; and
[0032] The processor executes the steps of the control method for the multi-energy heating system as described above by calling programs or instructions stored in the memory.
[0033] A fourth aspect of the present invention is to provide a computer-readable storage medium storing a program or instructions that cause a computer to perform the steps of the control method for a multi-energy heating system as described above.
[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.
[0035] (1) The control method of the multi-energy heating system provided by the present invention prioritizes the activation of the solar heating module during off-peak electricity price periods and when there is sufficient sunlight, and intelligently switches to the heat pump heating module or electric heating module for auxiliary heating when the solar heating capacity is insufficient. On the basis of optimizing power configuration and reducing heating costs, the stability and efficiency of hot water supply are ensured.
[0036] (2) The control method of the multi-energy heating system provided by the present invention obtains the current water temperature rise rate in real time during the operation of the solar heating module, and selectively controls the heat pump heating module and the electric heating module to start or standby according to the water temperature rise rate, which fully considers the user's current water use status and further ensures the stability and efficiency of hot water supply.
[0037] (3) The control method of the multi-energy heating system provided by the present invention prioritizes the use of the waste heat of the solar heating module for heat preservation during peak electricity price periods, and prioritizes the use of the low-power heat preservation mode of the heat pump heating module for heat preservation when the current water temperature decrease rate is higher than the preset heat preservation decrease rate, thereby further reducing energy consumption.
[0038] (4) The control method of the multi-energy heating system provided by the present invention controls the heat pump heating module and the electric heating module to start and heat the hot water to the target temperature when there is less time remaining during the off-peak electricity price period. This can extend the heat preservation time during the peak electricity price period and reduce energy consumption. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0048] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0050] Figure 1 A multi-energy heating system 100 according to an exemplary embodiment of the present invention is shown. The multi-energy heating system 100 can be a hot water system or a heating system, and the present invention does not limit it to either.
[0051] like Figure 1 As shown, the multi-energy heating system 100 includes a controller 110, a communication module 120, an electric heating module 130, a solar heating module 140, and a heat pump heating module 150.
[0052] Among them, the solar heating module 140 uses solar energy to heat water, which is pollution-free and low-cost when there is sufficient sunlight; the heat pump heating module 150 has relatively high energy efficiency; and the electric heating module 130 provides stable heating but has relatively high energy consumption. Each of these three heating modules has its advantages. This invention prioritizes the activation of the solar heating module 140 during off-peak electricity hours and when there is sufficient sunlight. When solar heating capacity is insufficient, it intelligently switches to the heat pump heating module 150 or the electric heating module 130 for auxiliary heating. This optimizes power allocation, reduces heating costs, and ensures the stability and efficiency of hot water supply.
[0053] The controller 110 controls the operating modes of the electric heating module 130, the solar heating module 140, and the heat pump heating module 150. The communication module 120 communicates with external devices (such as a server) to obtain peak-valley time-of-use electricity pricing schedules. Furthermore, it should be noted that the controller 110 has a built-in clock for determining the current time.
[0054] In some embodiments, the multi-energy heating system 100 further includes a detection module 160, which may include, for example, a temperature sensor for detecting the water temperature of the multi-energy heating system 100 and a tester for detecting the solar thermal conversion efficiency. It should be noted that the temperature sensor and the solar thermal conversion efficiency tester can be any equipment capable of performing the detection function in the art, and will not be described in detail here.
[0055] In some other embodiments, to reduce costs, the detection module 160 does not include a tester for detecting the solar thermal conversion efficiency, but the controller 110 can communicate with external devices (such as servers) through the communication module 120 to obtain the current weather conditions, and then determine the solar thermal conversion efficiency at the current time based on the current weather conditions.
[0056] In addition, the multi-energy heating system 100 may also include a display module 170 for displaying information such as current water temperature, operating mode, and electricity price period.
[0057] Figure 2 The flowchart of a control method 200 for a multi-energy heating system 100 according to an exemplary embodiment of the present invention is shown.
[0058] like Figure 2 As shown, the execution of the control method 200 for the multi-energy heating system 100 includes the following steps:
[0059] S210. When it is determined that the current time falls within the local off-peak electricity price period, obtain the solar thermal conversion efficiency of the solar energy at the current time.
[0060] S220. When it is determined that the solar thermal conversion efficiency of the current time exceeds the preset conversion efficiency, control the solar heating module to start.
[0061] S230. During the operation of the solar heating module, the current water temperature rise rate is obtained;
[0062] S240: Selectively control the start-up of the heat pump heating module and the electric heating module based on the relationship between the current water temperature rise rate and the preset heating rise rate.
[0063] It should be understood that the steps shown in the control method 200 of the multi-energy heating system 100 are not exclusive. The control method 200 of the multi-energy heating system 100 may also include additional steps not shown and / or the steps shown may be omitted. The scope of the invention is not limited in this respect. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the invention can be combined with each other. In addition, unless explicitly defined or contradicted by the context, the specific steps included in the method described in the invention are not limited to the order in which they are described, but can be performed in any order or in parallel.
[0064] Before providing a detailed explanation of steps S210 to S240, the steps for the controller 110 to obtain the local off-peak electricity price period and peak electricity price period will be introduced first.
[0065] In detail, controller 110 sends a search request to a server that is communicatively connected to controller 110 to obtain the peak-valley time-of-use electricity price schedule published by the local power supply department. The server sends the search results to controller 110, and after receiving the peak-valley time-of-use electricity price schedule sent by the server, controller 110 determines the local off-peak electricity price period and peak electricity price period based on the peak-valley time-of-use electricity price schedule.
[0066] It should be noted that the division of off-peak and peak electricity pricing periods varies across different provinces and cities, and relevant local departments adjust these periods according to market dynamics. Therefore, controller 110 needs to periodically send search requests to the server to obtain the latest peak-valley time-of-use pricing schedule. For example, controller 110 can send search requests to the server on the 1st and 15th of each month, or every Monday.
[0067] Furthermore, when the controller 110 sends a search request to the server, the search request includes the location and time information of the multi-energy heating system 100. This ensures the accuracy of the off-peak and peak electricity price periods. Understandably, this is the foundation for the entire multi-energy heating system 100 to automatically control the operation of each heating module based on peak and off-peak electricity prices. Only by accurately determining the electricity price period can the corresponding heating module operating mode and energy-saving strategy be activated in a timely manner.
[0068] For example, the peak-valley time-of-use electricity pricing schedule for a certain area is as follows:
[0069] Table 1: Daily Electricity Price Schedule for July, August, and September
[0070] Peak electricity price period Off-peak electricity pricing periods 16:00-24:00 9:00-16:00,0:00-9:00
[0071] Table 2: Daily Electricity Price Schedule for January and December
[0072] Peak electricity price period Off-peak electricity pricing periods 15:00-23:00 8:00-15:00, 23:00-8:00 the next day
[0073] Table 3: Daily Electricity Price Schedule for Other Months
[0074]
[0075] In addition, some provinces and cities also have designated periods for flat and / or peak electricity prices. For example, the off-peak electricity price is 20% lower than the flat price, while the peak price is 20% higher than the high-peak price. This invention exemplarily merges the flat period into the off-peak electricity price period and merges the peak electricity price period into the high-peak electricity price period.
[0076] In some implementations, the controller 110 may have a built-in positioning chip to obtain the location information of the multi-energy heating system 100. Alternatively, the controller 110 may receive location information input by a user.
[0077] Steps S210 to S240 will be described in detail below.
[0078] Specifically, in step S210, when the controller 110 of the multi-energy heating system 100 determines that the current time falls within a local off-peak electricity price period based on the time indicated by its built-in clock, it uses a solar thermal conversion efficiency tester to obtain the solar thermal conversion efficiency at the current time. In step S220, when the controller 110 of the multi-energy heating system 100 determines that the solar thermal conversion efficiency at the current time exceeds a preset conversion efficiency, it means that solar energy can be used to heat water, and therefore controls the solar heating module 140 to start. In step S230, during the operation of the solar heating module 140, a temperature sensor detects the current water temperature and calculates the current water temperature rise rate. Then, in step S240, the controller 110 of the multi-energy heating system 100 selectively controls the heat pump heating module 150 and the electric heating module 130 to start based on the relationship between the current water temperature rise rate and the preset heating rise rate, thereby optimizing power configuration, reducing heating costs, and ensuring the stability and efficiency of hot water supply.
[0079] In specific implementation step S240, when the controller 110 of the multi-energy heating system 100 determines that the current water temperature rise rate during the operation of the solar heating module 140 is lower than the preset heating rise rate, it means that the solar hot water capacity is insufficient or the user is currently in a stage of high hot water consumption. At this time, the controller 110 controls the heat pump heating module 150 to start auxiliary water heating to ensure the stability of hot water supply and continue to obtain the current water temperature rise rate. Alternatively, when the controller 110 of the multi-energy heating system 100 determines that the current water temperature rise rate during the operation of the solar heating module 140 is higher than or equal to the preset heating rise rate, it means that the solar hot water capacity is sufficient or the user is currently in a stage of low hot water consumption. At this time, the controller 110 controls the heat pump heating module 150 and the electric heating module 130 to standby mode to reduce heating costs.
[0080] When the controller 110 of the multi-energy heating system 100 determines that the current water temperature rise rate during the operation of the heat pump heating module 150 is still lower than the preset heating rise rate, it means that the user is currently in a stage where hot water consumption is further increasing. At this time, the controller 110 controls the electric heating module 130 to start auxiliary water heating to ensure the stability of hot water supply. Alternatively, when the controller 110 of the multi-energy heating system 100 determines that the current water temperature rise rate during the operation of the heat pump heating module 150 is higher than or equal to the preset heating rise rate, it means that the combined heating effect of the solar heating module 140 and the heat pump heating module 150 can cover the user's hot water demand. The controller then sets the electric heating module 130 to standby mode to reduce heating costs.
[0081] Furthermore, in step S220, when the controller 110 of the multi-energy heating system 100 determines that the solar thermal conversion efficiency of the solar energy at the current time does not exceed the preset conversion efficiency, it means that it is a cloudy day or night, and solar energy cannot be used to heat water at this time. In order to ensure the stability of hot water supply, the controller 110 controls the heat pump heating module 150 to start heating water, and during the operation of the heat pump heating module 150, the current water temperature rise rate is obtained, and then the start and stop of the electric heating module 130 is controlled according to the relationship between the current water temperature rise rate and the preset heating rise rate.
[0082] That is, when the current water temperature rise rate is lower than the preset heating rise rate, it means that the user's hot water demand cannot be met by only starting the heat pump heating module 150 to heat the water, and the electric heating module 130 should be controlled to start auxiliary water heating. When the current water temperature rise rate is higher than or equal to the preset heating rise rate, it means that the user's hot water demand can be met by only starting the heat pump heating module 150 to heat the water, and there is no need to control the electric heating module 130 to start, thus reducing costs.
[0083] Furthermore, in step S210, when the controller 110 of the multi-energy heating system 100 determines that the current time falls within the local peak electricity price period, it uses a temperature sensor to acquire the current water temperature in real time and determines whether the current hot water temperature can meet the user's water demand. That is, whether the current water temperature is within the user's acceptable range. It should be noted that the controller 110 of the multi-energy heating system 100 stores a minimum insulation temperature that can determine whether the current water temperature is within the user's acceptable range.
[0084] Specifically, when the controller 110 of the multi-energy heating system 100 determines that the current water temperature is lower than the minimum insulation temperature, it prioritizes controlling the solar heating module 140 to start insulation and obtains the current water temperature reduction rate. When it is determined that the current water temperature reduction rate during the insulation process of the solar heating module 140 is higher than the preset insulation reduction rate, it indicates that the current hot water temperature when the solar heating module 140 is used for insulation alone cannot meet the user's water demand. At this time, it controls the heat pump heating module 150 to start insulation mode and waits for the next off-peak electricity price period before controlling the heat pump heating module 150 and the electric heating module 130 to start heating.
[0085] It should be noted that the heating power of the heat pump heating module 150 in the heat preservation mode is lower than that in the heating mode. That is, the power consumption of the heat pump heating module 150 in the heat preservation mode is lower than that in the heating mode.
[0086] Furthermore, in step S210, when the controller 110 of the multi-energy heating system 100 determines that the remaining time of the off-peak electricity price period is lower than a preset time threshold, it indicates that the peak electricity price period is about to begin. At this time, the current water temperature is obtained, and when it is determined that the difference between the current water temperature and the target temperature exceeds a preset difference threshold, it indicates that the current water temperature is insufficient to meet the user's water demand during the peak electricity price period. At this time, the heat pump heating module 150 and the electric heating module 130 are controlled to start until the current water temperature reaches the target temperature, so as to avoid the heat pump heating module 150 and the electric heating module 130 being started for a long time during the peak electricity price period, thereby reducing energy consumption and improving energy utilization efficiency.
[0087] It is understandable that during the execution of steps S210 to S240, when the controller 110 of the multi-energy heating system 100 determines that the current water temperature has reached the target temperature, it prioritizes controlling the solar heating module 140 to enter the heat preservation mode and controls the heat pump heating module 150 and the electric heating module 130 to enter the standby state.
