Technical Field

[0001] The present application relates to the field of energy utilization technology, and in particular to a control method, product, equipment and medium based on a solar heat pump water heating system. Background Art

[0002] With the continuous growth of global energy demand, especially the significant increase in energy consumption for building production and domestic hot water, energy transformation and energy conservation and emission reduction have become urgent tasks. According to data from the International Energy Agency (IEA), global energy demand continues to rise, and the report released by the China Building Energy Conservation Association also reveals that China's building operation phase energy consumption and carbon emissions account for a large proportion of the national total, and this proportion shows an increasing trend year by year. This trend has not only exacerbated the energy crisis, but also led to increasingly serious environmental pollution problems. In order to meet this challenge, actively optimizing the energy structure, reducing primary energy consumption, and developing and applying renewable energy have become important strategies to promote the revolution in energy production and consumption and promote energy transformation. As a clean and renewable new energy source, solar energy has huge development potential, and solar water heaters are one of the important forms of solar energy utilization.

[0003] In rural areas, the installation and use of solar water heaters are very favorable because houses are neatly arranged, equipped with running water, mostly low-rise buildings and have a large per capita usable area. However, despite the many advantages of solar water heaters, the changeable climate and weather limit their ability to provide continuous and stable hot water. In order to make up for this shortcoming, the solar energy and heat pump combined heating system came into being.

[0004] The solar energy and heat pump combined heating system in the related art usually switches the system's working mode manually or automatically according to the real-time weather conditions. However, different users have different heating needs, and this method cannot intelligently adjust the working mode according to the user's personalized heating needs. Summary of the invention

[0005] In order to solve the problem that the existing technology cannot meet the differentiated heat needs of users, the present application provides a control method, product, equipment and medium based on a solar heat pump water heating system.

[0006] In the first aspect, the present application provides a control method based on a solar heat pump water heating system, which adopts the following technical solution: A control method based on a solar heat pump hot water system, comprising: Acquire historical heating data under different heating modes, the historical heating data including historical environmental data, historical equipment parameters and historical water temperature data corresponding to the timestamp, the heating modes including: solar energy heating mode alone, solar energy heat pump combined heating mode, heat pump heating mode alone; Determining switching conditions of different heating modes based on the historical environmental data, historical equipment parameters and historical water temperature data; estimating heat loss based on historical heating data in a single heating mode of the heat pump; The environmental data and equipment parameters corresponding to the heating system are acquired in real time, and a target heating mode is dynamically determined based on the switching conditions, the environmental data, the equipment parameters and the heat loss, and the heating system is controlled to perform heating according to the target heating mode.

[0007] By adopting the above technical solution, the switching conditions of different heating modes are determined based on the historical environmental data, historical equipment parameters and historical water temperature data, so that the heating system can automatically adjust the heating mode, thereby optimizing energy utilization and ensuring the user's heating needs. Determining heat loss helps to more accurately control the operation of the heating system heat pump and reduce unnecessary energy waste. The environmental data and equipment parameters of the heating system are obtained in real time and the target heating mode is dynamically determined, ensuring that the heating system always operates in the optimal state, improving the system energy efficiency and stability, and bringing a better user experience.

[0008] In a preferred example, the present application may be further configured as follows: the historical device parameter includes water storage capacity; the switching condition includes a first switching condition and a second switching condition; The determining of the switching conditions of different heating modes based on the historical environmental data, historical equipment parameters and historical water temperature data includes: Determining first historical heating data corresponding to the solar energy heating mode from the historical heating data; Determine whether each historical water temperature data in the first historical heating data satisfies a preset effective heating determination condition, and obtain first data that satisfies the preset effective heating determination condition and second data that does not satisfy the preset effective heating determination condition, wherein the first data and the second data both include a correspondence between a plurality of historical environmental data, historical equipment parameters, and historical water temperature data; storing the first data as a first switching condition, so as to switch between the solar energy heating mode alone and the solar heat pump combined heating mode based on the first switching condition; The second data is stored as a second switching condition, so as to switch between the solar heat pump combined heating mode and the heat pump single heating mode based on the second switching condition.

[0009] By adopting the above technical scheme, the first data that meets the preset effective heating judgment condition and the second data that does not meet the preset effective heating judgment condition are divided, and the first data is stored as the first switching condition, which ensures that when the environmental conditions are sufficient to effectively increase the water temperature, the solar energy heating mode is preferentially selected to make full use of renewable resources, and when the environmental conditions are not sufficient to effectively increase the water temperature, the solar heat pump combined heating mode is selected to ensure the stable increase of the water temperature; the second data is stored as the first switching condition, which ensures that when solar energy heating is basically useless under extreme conditions, the heat pump heating mode is directly selected. This intelligent switching mechanism helps to improve energy utilization efficiency and reduce unnecessary energy consumption.

[0010] In a preferred example, the present application may be further configured as follows: the equipment parameters include the current water storage capacity; The dynamically determining the target heating mode based on the switching condition, the environmental data, the device parameters and the heat loss comprises: Determine the first historical environmental data corresponding to the current water storage capacity from the second switching condition, and judge whether the environmental data reaches the first historical environmental data; If the environmental data does not reach the first historical environmental data, determining the heat pump separate heating mode as the target heating mode; If the environmental data reaches the first historical environmental data, a target heating mode is determined based on the switching condition, the environmental data, the device parameters and the heat loss.

[0011] By adopting the above technical solution, introducing the current water storage capacity as an equipment parameter, determining the first historical environmental data from the second switching condition as a basis for judgment, and introducing heat loss estimation to optimize energy efficiency, the intelligent control and optimized operation of the heating system are realized, which not only improves the energy efficiency and stability of the system, but also enhances the adaptability and reliability of the system, bringing users a more comfortable and convenient use experience.

[0013] By adopting the above technical solution, setting the heating termination temperature can meet the user's personalized heating needs and improve the user experience. Historical data is used to predict the maximum water temperature that can be achieved by solar energy heating alone under current conditions. The determined maximum water temperature and the heating termination temperature are compared to determine the target heating mode, which not only ensures the stable increase in water temperature but also reduces energy consumption. By precisely controlling the heat pump power, the energy efficiency and stability of the system can be further optimized.

[0014] In a preferred example, the present application may be further configured as follows: determining the heat pump power in the target heating mode based on the heat loss includes: Calculating a temperature difference between the heating termination temperature and the maximum water temperature, and calculating a heat difference based on the temperature difference and the current water storage capacity; The heat pump power is calculated based on the heat difference and the heat loss.

[0015] By adopting the above technical solution, accurately calculating the heat difference and taking into account heat loss, the power required by the heat pump can be determined more accurately, avoiding overheating or underheating, thereby improving the energy efficiency of the entire heating system. By accurately controlling the heat pump power, it can be ensured that the water temperature reaches the heating termination temperature set by the user as quickly as possible, while avoiding unnecessary energy consumption and improving user comfort and satisfaction.

[0016] In a preferred example, the present application can be further configured as follows: the method further includes: Obtain predicted environmental data for the target area and equipment parameters for each heating system; Predicting a heating mode of each heating system in the target area in a future period based on the switching condition, the predicted environmental data, the heat loss, and equipment parameters of each heating system; The heating modes of the heating systems in the target area are input into a preset energy consumption prediction model, and the operating energy consumption of the target area in a future period output by the preset energy consumption prediction model is received.

[0017] By adopting the above technical solutions, the heating mode and operating energy consumption in future time periods can be predicted, and the heating system can be planned and scheduled in advance, which will help avoid energy shortages or equipment overloads during peak hours and ensure the stable operation of the heating system. Through prediction and planning, renewable energy such as solar energy can be used more reasonably, which will help to discover potential energy-saving opportunities and improvement points, and provide data support for optimizing system design and operation strategies.

[0019] By adopting the above technical solution and calculating heat loss based on actual historical heating data, the energy efficiency performance of the heat pump under different environmental conditions and equipment parameters can be more accurately reflected.

[0030] The heat load of the solar heat pump hot water system is determined according to the water load of rural single-family residential buildings. The main components of the heating system, such as the heat pump unit (compressor, condenser, evaporator, expansion valve), flat-plate solar collector, hot water storage tank and other components, are selected and calculated, and a split solar heat pump hot water system is built for heating.

[0031] The present application embodiment provides a control method based on a solar heat pump water heating system, such as Figure 1 As shown, the method provided in the embodiment of the present application is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. The method includes steps S101 to S104, wherein: S101. Acquire historical heating data under different heating modes, where the historical heating data includes historical environmental data, historical equipment parameters and historical water temperature data corresponding to a timestamp. The heating modes include: solar energy heating mode alone, solar heat pump combined heating mode, and heat pump heating mode alone.

[0032] Specifically, the heating mode is one of three working modes that the heating system can choose. The historical heating data under different heating modes can obtain the data generated by the actual operation of the heating system, and can also be obtained by experimenting with the experimental prototype of the heating system. The historical heating data is the data of the preset heating time starting from the beginning of heating in different heating modes. The preset heating time is the expected maximum time required for the water temperature to rise to the set temperature, which is pre-set by the technician. The set temperature is the water temperature required by the user to ensure the heating efficiency. If the water temperature has stabilized before the preset heating time is reached, the data between the start of heating and the moment of reaching stability will be used as the historical heating data. Among them, the moment when the water temperature reaches stability can be manually determined, and can also be determined by the temperature change rate per unit time, which is not specifically limited in this embodiment.

[0033] Historical environmental data includes light intensity and ambient temperature of the external environment. Historical equipment parameters include water storage capacity of the heat storage tank and historical heat pump power. In solar heating mode alone, historical equipment parameters only include water storage capacity. Different water storage capacities can be set according to actual user water demand. Optional water storage capacities include 150L, ​​100L and 80L.

[0034] S102: Determine switching conditions for different heating modes based on historical environmental data, historical equipment parameters, and historical water temperature data.

[0035] Among them, the higher the light intensity and the higher the ambient temperature, the better the solar heat generation effect, the smaller the water storage capacity, and the faster the water temperature rises.

[0036] The data of solar energy heating mode alone is determined from the historical heating data as the first historical heating data. The first historical environment data contains multiple data, each of which represents the correspondence between specific historical environment data and storage capacity and historical water temperature data. It is judged whether the historical water temperature data in each data of the first historical heating data meets the preset effective heating condition. The preset effective heating condition can be that the absolute value of the temperature difference between the start and end time in the historical water temperature data exceeds the preset temperature difference. If it does not exceed the preset temperature difference, it indicates that the data does not meet the preset effective heating condition. The preset temperature difference can be flexibly set according to actual needs, indicating that the temperature has changed significantly during the heating period.

[0037] The first historical heating data is divided into first data that meets the preset effective heating condition and second data that does not meet the preset effective heating condition, the first data is stored as a first switching condition, and the second data is stored as a second switching condition, the first switching condition is used to switch between the solar energy heating mode alone and the solar heat pump combined heating mode, and the second switching condition is used to switch between the solar heat pump combined heating mode and the heat pump heating mode alone. The first switching condition and the second switching condition are combined into switching conditions for different heating modes.

[0038] S103 , estimating heat loss based on historical heating data in the heat pump single heating mode.

[0039] Specifically, the heat loss is the heat loss of the heat pump, which is expressed as the ratio of the heat absorbed by water to the electrical energy consumed by the heat pump. In actual work, the lower the ambient temperature, the greater the heat loss of the heat pump. Therefore, the heat loss estimated based on the historical heating data in the heat pump single heating mode includes the heat loss of the heat pump under different environmental data.

[0040] Specifically, the second historical heating data in the heat pump single heating mode is obtained from the historical heating data. The second historical heating data contains multiple data, each of which represents the historical water temperature data corresponding to specific historical environmental data and historical equipment parameters. For each data, the water absorption heat is determined based on the historical water temperature data and the water storage capacity in the historical equipment parameters, and the electric energy consumption is calculated based on the historical heat pump power. The ratio of the water absorption heat and the electric energy consumption is used as the heat loss of the heat pump corresponding to the historical environmental data and the historical equipment parameters. The heat loss in the heat pump single heating mode includes the heat loss under different historical environmental data and historical equipment parameters.

[0041] S104, acquiring the environmental data and equipment parameters corresponding to the heating system in real time, and dynamically determining the target heating mode based on the switching conditions, environmental data, equipment parameters and heat loss, and controlling the heating system to perform heating according to the target heating mode.

[0042] Specifically, the environmental data and equipment parameters are current data obtained during the actual operation of any heating device, and the equipment parameters include the current water storage capacity. The first historical environmental data corresponding to the current water storage capacity is determined from the second switching condition. If the environmental data does not reach the first historical environmental data, the heat pump heating mode is determined as the target heating mode; if the environmental data reaches the first historical environmental data, the maximum water temperature of the historical water temperature data corresponding to the environmental data and the current water storage capacity is determined from the first switching condition, and the maximum water temperature is compared with the heating termination temperature set and input by the user.

[0043] If the maximum water temperature is not lower than the heating termination temperature, the solar heat pump combined heating mode is determined as the target heating mode. If the maximum water temperature is lower than the heating termination temperature, the solar heat pump combined heating mode is determined as the target heating mode. This embodiment determines the switching conditions of different heating modes based on historical environmental data, historical equipment parameters and historical water temperature data, so that the heating system can automatically adjust the heating mode, thereby optimizing energy utilization and ensuring the user's heating needs. Determining heat loss helps to more accurately control the operation of the heating system heat pump and reduce unnecessary energy waste. The environmental data and equipment parameters of the heating system are obtained in real time and the target heating mode is dynamically determined, ensuring that the heating system always operates in the optimal state, improving the system energy efficiency and stability, and thus bringing a better user experience.

[0044] In a possible implementation of the embodiment of the present application, the historical device parameter includes a water storage capacity; the switching condition includes a first switching condition and a second switching condition; The switching conditions of different heating modes are determined based on historical environmental data, historical equipment parameters and historical water temperature data, including: Determine first historical heating data corresponding to the solar energy heating mode from the historical heating data; Determine whether each historical water temperature data in the first historical heating data satisfies a preset effective heating determination condition, and obtain first data that satisfies the preset effective heating determination condition and second data that does not satisfy the preset effective heating determination condition, wherein the first data and the second data both include a correspondence between a plurality of historical environmental data, historical equipment parameters, and historical water temperature data; storing the first data as a first switching condition, so as to switch between a solar energy heating mode alone and a solar energy heat pump combined heating mode based on the first switching condition; The second data is stored as a second switching condition to switch between the solar heat pump combined heating mode and the heat pump single heating mode based on the second switching condition.

[0045] Specifically, each piece of data in the first historical heating data is traversed, each piece of data includes a correspondence between a piece of historical environmental data, a historical equipment parameter, and a historical water temperature data, and the data that meets the preset effective heating judgment condition is divided into the first data, and the data that does not meet the preset effective heating condition is divided into the second data. The first data indicates that the heating system can effectively heat in the solar energy heating mode, and the second data indicates that the heating effect of the heating system is not good in the solar energy heating mode.

[0046] This embodiment divides the first data that meets the preset effective heating judgment condition into the second data that does not meet the preset effective heating judgment condition, and stores the first data as the first switching condition, thereby ensuring that when the environmental conditions are sufficient to effectively increase the water temperature, the solar energy heating mode is preferentially selected to make full use of renewable resources, and when the environmental conditions are not sufficient to effectively increase the water temperature, the solar heat pump combined heating mode is selected to ensure a stable increase in the water temperature; the second data is stored as the first switching condition, thereby ensuring that when solar energy heating is basically useless under extreme conditions, the heat pump heating mode is directly selected. This intelligent switching mechanism helps to improve energy utilization efficiency and reduce unnecessary energy consumption.

[0047] A possible implementation of the embodiment of the present application is to estimate heat loss based on historical heating data in the heat pump single heating mode, including: Acquire second historical heating data in the heat pump single heating mode from the historical heating data; Determine the amount of heat absorbed by water based on the target historical water temperature data, and determine the power consumption based on the historical heat pump power in the target historical equipment parameters; calculate the ratio of the amount of heat absorbed by water to the power consumption, and obtain the heat loss of the heat pump corresponding to the target historical environmental data and the target historical equipment parameters, the target historical environmental data, the target historical equipment parameters and the target historical water temperature data being a set of data corresponding to each other in the second historical heating data; The corresponding relationship between different historical environmental data and historical equipment parameters and heat loss in the second historical heating data is used as the heat loss in the heat pump single heating mode.

[0048] In this embodiment, the second historical heating data includes multiple data, each of which includes historical environmental data, historical equipment parameters and historical water temperature data corresponding to the timestamp, and the target data is any one of the data. Water absorption heat Q1=m×c×(Tf-Ti), where m is the water mass corresponding to the water storage capacity in the target historical equipment parameters, obtained by calculating the product of the water storage capacity and the water density; c is the specific heat capacity of water; Ti is the water temperature at the start time of heating in the target historical water temperature data, and Tf is the water temperature at the end time of heating in the target historical water temperature data. Electric energy consumption E=P×t, where P is the historical heat pump power, and t is the heating time, that is, the duration corresponding to the target historical water temperature data.

[0049] Finally, the different historical environmental data and historical equipment parameters in the second historical equipment parameters are associated with the calculated heat loss to obtain the corresponding relationship of the heat loss in the heat pump single heating mode.

[0050] This embodiment calculates heat loss based on actual historical heating data, which can more accurately reflect the energy efficiency performance of the heat pump under different environmental conditions and equipment parameters, and establishes a corresponding relationship between heat loss and environmental data and equipment parameters, which helps to accurately set the heat pump power based on heat loss and reduce the energy consumption loss of the heat pump.

[0051] In a possible implementation of the embodiment of the present application, the equipment parameters include the current water storage capacity; The target heating mode is dynamically determined based on switching conditions, environmental data, equipment parameters and heat loss, including: Determine the first historical environmental data corresponding to the current water storage capacity from the second switching condition, and judge whether the environmental data reaches the first historical environmental data; If the environmental data does not reach the first historical environmental data, the heat pump separate heating mode is determined as the target heating mode; If the environmental data reaches the first historical environmental data, the target heating mode is determined based on the switching condition, the environmental data, the equipment parameters and the heat loss.

[0052] Specifically, the second switching condition is used to switch between the solar heat pump combined heating mode and the heat pump single heating mode, and the second switching condition includes the correspondence between different historical environmental data, historical equipment parameters and historical water temperature data. The environmental data and equipment parameters are data corresponding to the actual operation of the current heating system. The first historical environmental data corresponding to the current water storage capacity is determined from the second switching condition, including: searching for a piece of data whose historical water storage capacity is equal to the current water storage capacity from the second switching condition. If it cannot be found, then searching for two pieces of data closest to the historical water storage capacity and the current water storage capacity, and the historical water storage capacity of one of the two pieces of data is greater than the current water storage capacity, and the historical water storage capacity of the other piece of data is less than the current water storage capacity. The interpolation method is used to obtain the historical environmental data corresponding to the current water storage capacity, that is, the first historical environmental data. The historical environmental data includes light intensity and ambient temperature, and the light intensity and ambient temperature are respectively differentiated to obtain the first historical environmental data.

[0053] Furthermore, it is determined whether the environmental data at the current moment reaches the first historical environmental data, including: comparing the environmental data with the light intensity and ambient temperature in the first historical environmental data respectively. If any one of the items is not reached, it is determined that the environmental data does not reach the first historical environmental data, that is, the environmental data at the current moment is not conducive to solar heating. At this time, solar heating is not turned on, and heat pump heating alone is determined as the target heating mode.

[0054] If both the light intensity and the ambient temperature are reached, it is determined that the environmental data reaches the first historical environmental data. At this time, solar heating is taken into account in the heating mode, and then the target heating mode is determined from the solar energy heating mode alone and the solar heat pump combined heating mode based on the switching conditions, environmental data, equipment parameters and heat loss.

[0055] This embodiment optimizes energy efficiency by introducing the current water storage capacity as an equipment parameter, determining the first historical environmental data from the second switching condition as a basis for judgment, and introducing heat loss estimation, thereby realizing intelligent control and optimized operation of the heating system. This not only improves the energy efficiency and stability of the system, but also enhances the adaptability and reliability of the system, bringing users a more comfortable and convenient use experience.

[0056] In a possible implementation of the embodiment of the present application, the device parameters also include a heating termination temperature set and input by a user; Determine the target heating mode based on switching conditions, environmental data, equipment parameters and heat loss, including: Determine the maximum water temperature of the historical water temperature data corresponding to the environmental data and the current water storage capacity from the first switching condition, and compare the maximum water temperature with the heating termination temperature; If the maximum water temperature is not lower than the heating termination temperature, the solar energy heating mode alone is determined as the target heating mode; If the maximum water temperature is lower than the heating termination temperature, the solar heat pump combined heating mode is determined as the target heating mode, and the heat pump power in the target heating mode is determined based on the heat loss.

[0057] In this embodiment, the heating termination temperature is the desired water temperature set by the user. The maximum water temperature of the historical water temperature data corresponding to the environmental data and the current water storage capacity is determined from the first switching condition, and the obtained maximum water temperature is the highest temperature that can be reached only by solar heating under the environmental data at the current moment and the current water storage capacity. If the maximum water temperature is not lower than the heating termination temperature, it means that solar heating can meet the user's heating needs and there is no need to start the heat pump, that is, the solar energy heating mode alone is determined as the target heating mode, which can save resources; if the maximum water temperature is lower than the heating termination temperature, it means that solar energy heating cannot meet the user's heating needs and the heat pump needs to be started, and the solar heat pump combined heating mode is determined as the target heating mode.

[0058] This embodiment can meet the user's personalized heating needs by setting the heating termination temperature, thereby improving the user experience. Historical data is used to predict the maximum water temperature that can be achieved by solar energy heating alone under current conditions. The determined maximum water temperature is compared with the heating termination temperature to determine the target heating mode, which not only ensures the stable increase in water temperature but also reduces energy consumption. By accurately controlling the heat pump power, the energy efficiency and stability of the system can be further optimized.

[0059] A possible implementation of the embodiment of the present application is to determine the heat pump power in the target heating mode based on the heat loss, including: Calculate the temperature difference between the heating end temperature and the maximum water temperature, and calculate the heat difference based on the temperature difference and the current water storage capacity; The heat pump power is calculated based on the heat difference and heat loss.

[0060] In this embodiment, the maximum water temperature indicates the maximum water temperature that can be reached by solar energy heating alone, and the calculated temperature difference indicates how much the water temperature needs to be raised to reach the heating termination temperature required by the user. Heat difference Q2 = m × c × ΔT, where m is the water mass corresponding to the water storage capacity in the target historical device parameters, obtained by calculating the product of the water storage capacity and the water density; c is the specific heat capacity of water; and ΔT is the temperature difference.

[0061] Furthermore, the heat loss corresponding to the environmental data and the current water storage capacity is determined from the corresponding relationship of heat loss through an interpolation algorithm as the target heat loss. The preset heating time is obtained, which means the expected maximum time required for the water temperature to rise to the set temperature set by the technician in advance. The target heat loss means the ratio of the heat absorbed by the water and the energy consumed by the heat pump under the condition of heat pump heating. The ratio of the heat difference and the target heat loss is calculated to obtain the energy required by the heat pump. The ratio of the energy required by the heat pump to the preset heating time is calculated as the heat pump power.

[0062] This embodiment can more accurately determine the power required by the heat pump by accurately calculating the heat difference and taking heat loss into account, thereby avoiding overheating or underheating, thereby improving the energy efficiency of the entire heating system.

For any heating system in the target area, the heating mode of the heating system in the future period can be predicted based on the switching conditions, predicted environmental data, heat loss, and the equipment parameters of the heating system. The heating mode may change dynamically over time in the future period, and finally the heating mode of each heating system in the target area in the future period is obtained.

[0065] The preset energy consumption prediction model is trained based on the heating mode and energy consumption data, and is used to input the heating mode to predict the operating energy consumption. The operating energy consumption may include system power consumption and performance coefficient, etc.

[0066] This embodiment can plan and schedule the heating system in advance by predicting the heating mode and operating energy consumption in future time periods, which helps to avoid energy shortages or equipment overloads during peak hours and ensure the stable operation of the heating system.
