[0034] To address the technical problems of high heat loss and low utilization rate in existing dual-tank hot water systems, this application provides a water supply system and its control method, device, supply equipment, and storage medium, including: a heating container, an insulation container, and a heating module; the first water outlet of the heating container and the first water outlet of the insulation container are both connected to the water inlet of the heating module; the water outlet of the heating module is connected to the first water inlet of the heating container and the first water inlet of the insulation container; the second water inlet of the heating container is used to receive water resources to be heated. In this system, the heating container and the insulation container each form an independent circulation loop with the heating module, and the heating module can directly heat the heating container and the insulation container to improve the thermal energy utilization efficiency. This avoids the technical problems of high heat loss and low utilization rate caused by the long path loss of heat energy in existing dual-tank hot water systems, where heat energy must be transferred unidirectionally from the heating container to the insulation container.

[0035] The water supply system provided in this application will be further explained and described below with reference to the accompanying drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of this application.

[0036] See Figure 1 This is a schematic diagram of a water supply system provided in an embodiment of this application. Figure 1 As shown, the water supply system 10 may include: a heating module 11, a heating container 12, and an insulation container 13.

[0037] The heating module 11 is the core heat source of the water supply system 10. It is used to receive water flow from the heating container 12 and the heat preservation container 13, heat the water flow, and deliver the heated water flow to the corresponding container.

[0038] The heating container 12 is used to receive and store water resources to be heated, such as cold water to be heated.

[0039] The aforementioned insulated container 13 is used to store heated hot water and has an insulation layer to reduce heat loss of the hot water.

[0040] Furthermore, the heating module 11 may include a water outlet O1 and a water inlet I1.

[0041] Furthermore, the heating container 12 may include a first water outlet O2, a first water inlet I2, and a second water inlet I4. The second water inlet I4 of the heating container 12 is used to receive water resources to be heated.

[0042] Furthermore, the aforementioned heat-insulating container 13 may include a first water outlet O3 and a first water inlet I3.

[0043] In this embodiment of the application, based on the above-described structure of the water supply system 10, the heating container 12, the heat preservation container 13, and the heating module 11 can be connected in the following ways: The first water outlet O2 of the heating container 12 and the first water outlet O3 of the heat preservation container 13 are both connected to the water inlet I1 of the heating module 11.

[0044] This connection method enables dual-source selection of the water inlet path for the heating module 11. Depending on the operating mode of the heating module 11, it can flexibly select to transport water from the heating container 12, the insulation container 13, or a mixture of both to the heating module 11 for processing, providing a structural basis for different heating needs.

[0045] The water outlet O1 of the heating module 11 is connected to the first water inlet I2 of the heating container 12 and the first water inlet I3 of the heat preservation container 13, respectively. This connection method enables dual-path distribution of the heated hot water flow. The hot water output from the heating module 11 can be either returned to the heating container 12 for further heating or temperature maintenance, or directly transported to the insulation container 13 for storage and insulation, thus achieving precise delivery of thermal energy.

[0046] This completes the work. Figure 1 Structural description of the water supply system shown.

[0047] Furthermore, the operating modes of the heating module 11 mentioned above may include: heating container heating mode, heat preservation container heating mode, mixed heating mode, and water replenishment mode where the heating module is used for the heat preservation container.

[0048] Specifically, in the heating container heating mode, the heating module 11 can heat the water in the heating container 12 independently. The water flow path is: heating container 12, heating module 11, and return to heating container 12. This mode is suitable for scenarios where the water temperature in the heating container 12 is low and it is necessary to prioritize raising its base temperature, or to prepare for subsequent replenishment of hot water to the insulation container 13.

[0049] In the insulated container heating mode, the heating module 11 can heat the water in the insulated container 13 independently. The water flow path is: insulated container 13, heating module 11, return to insulated container 13. This mode can directly replenish the temperature of the hot water stored in the insulated container 13 when the water temperature in the insulated container 13 drops but the water temperature in the heating container 12 is high or does not need to be involved. This mode has a fast response speed, the shortest heat path, and high efficiency.

[0050] In the mixed heating mode, the heating module 11 can simultaneously heat the water in the heating container 12 and the insulation container 13 in a mixed circulation manner. The water flow in the heating container 12 and the insulation container 13 can be mixed proportionally before or after entering the heating module 11. This mode is suitable for scenarios where it is necessary to quickly equalize the water temperature in the heating container 12 and the insulation container 13, or when the water temperature in both the heating container 12 and the insulation container 13 is not up to standard and requires coordinated heating.

[0051] In the water replenishment mode where the heating module is used for the insulated container, it is mainly used to transport hot water from the heating container 12 to the insulated container 13. The water flow path is: heating container 12, heating module 11, insulated container 13. In this mode, the heating module 11 acts as a controllable heating transmission channel: when the water temperature flowing through the heating container 12 is lower than the temperature threshold set for the insulated container 13, the heating module 11 starts heating it; when the water temperature has reached or exceeded the temperature threshold set for the insulated container 13, the heating module 11 can only act as a transmission channel (its heating function is turned off or it operates at low power), thereby achieving energy-saving and efficient water replenishment.

[0052] based on Figure 1 The water supply system shown describes the heating process as follows: Based on the operating mode of the heating module, the target container and / or water source container are identified. If the operating mode is heating container mode, the target container is heating container 12, and the water supply system 10 will perform closed-loop circulation heating of the water in heating container 12. If the operating mode is insulated container mode, the target container is insulated container 13, and the water supply system 10 will perform closed-loop circulation heating of the water in insulated container 13. If the operating mode is mixed heating mode, the target container is a combination of heating container 12 and insulated container 13, and the water supply system 10 will perform coordinated or mixed heating of the water in both containers. If the operating mode is insulated container replenishment mode, the water source container is heating container 12, the target container is insulated container 13, and the water supply system 10 will transport the water (heated if necessary) from heating container 12 to insulated container 13.

[0053] The water supply system provided in this application breaks the limitation of traditional dual-tank systems where heat energy must be transferred unidirectionally from the heating container to the insulation container. Through a dual-source water inlet and dual-outlet design, the heating module can directly heat either container as needed, significantly shortening the heat transfer path and reducing heat loss in intermediate stages, thereby improving the overall thermal efficiency and response speed of the system.

[0054] See Figure 2 This is a schematic diagram of another water supply system provided in an embodiment of this application. Figure 2 The structure shown is in Figure 1 A three-way valve has been added to the structure shown. For example... Figure 2 As shown, the water supply system 20 may include Figure 1 The structure of the water supply system 10 shown, and the three-way valve 14.

[0055] The inlet I5 of the three-way valve 14 serves as the inlet I1 of the heating module 11. The heating module 11 includes a solar heating sub-module 11-1, a generator heating sub-module 11-2, and an electric heating sub-module 11-3.

[0056] The aforementioned three-way valve 14 is used to distribute the water from the heating container 12 and the insulation container 13 to different heating branches. Specifically, all the water flow can be directed to the first outlet O4 (entering the solar energy series branch, i.e., the solar energy input sub-module 11-1), all the water flow can be directed to the second outlet O5 (entering the electric heating parallel branch, i.e., the electronic heating sub-module 11-3), or it can be simultaneously diverted to the two outlets in a certain proportion (to achieve dual-path coordinated operation).

[0057] The aforementioned solar heating sub-module 11-1 is used to heat water flow using solar energy. It may include a solar collector, a circulating pump, and a related control system; however, this embodiment does not limit this.

[0058] The heating sub-module 11-2 of the above-mentioned unit can be a heat pump unit used for auxiliary heating of water flow.

[0059] The aforementioned electric heating sub-module 11-3 can be an electric heating tube or an instant electric heater, used to directly heat water by generating Joule heat through the flow of current through a resistive element.

[0060] Furthermore, the three-way valve 14 may include an inlet end I5, a first outlet end O4, and a second outlet end O5.

[0061] The aforementioned solar heating sub-module 11-1 may include a water inlet I 1-1 Outlet O 1-1 .

[0062] The heating sub-module 11-2 of the above-mentioned unit may include a water inlet I 2-1Outlet O 2-1 .

[0063] The aforementioned electric heating sub-module 11-3 may include a water inlet I 3-1 Outlet O 3-1 .

[0064] Based on this, in the embodiments of this application, the water supply system 20 may have the following connection methods: The first outlet O4 of the aforementioned three-way valve 14 is connected to the inlet I of the solar heating sub-module 11-1. 1-1 The water outlet O of the solar heating sub-module 11-1 1-1 Connect the water inlet I of the heating sub-module 11-2 of the unit. 2-1 The second outlet O5 of the three-way valve 14 is connected to the inlet I of the electric heating sub-module 11-3. 3-1 .

[0065] The water outlet O2-1 of the heating sub-module 11-2 and the water outlet O of the electric heating sub-module 11-3 of the above-mentioned unit 3-1 All are connected to the water outlet O1 of the heating module 11.

[0066] This connection constructs a composite heating path combining series and parallel connections. Specifically, the solar heating sub-module 11-1 is connected in series with the unit heating sub-module 11-2, enabling tiered energy utilization (such as solar preheating and heat pump fine heating); this series branch is then connected in parallel with the electric heating sub-module 11-3, providing an independent and rapid backup heating channel. This structure allows the water supply system 20 to flexibly and efficiently switch between various operating states, such as "solar priority series heating" and "electric heating independent operation," based on the inlet water temperature, target temperature, and energy availability.

[0067] The water supply system provided in this application embodiment, by introducing a three-way valve and constructing a composite heating path, can achieve intelligent linkage and optimal energy efficiency combination of multiple heat sources. The three-way valve dynamically distributes water flow according to control logic, prioritizing the water flow through the most energy-efficient solar branch, and only switching or activating the less energy-efficient branch when necessary. This maximizes the utilization of renewable energy and reduces the overall energy consumption of the system while ensuring heating capacity and response speed.

[0068] See Figure 3 This is a schematic diagram of another water supply system provided in an embodiment of this application. Figure 3 The structure shown is in Figure 2 Based on the structure shown, a water valve, a temperature detection module, and a fluid delivery module are added, and the water supply system 30 may include... Figure 2The structure of the central water supply system 20, and the first water valve 15, the second water valve 16, the third water valve 17, the fourth water valve 18, the first temperature detection module 19-1, the second temperature detection module 19-2, the third temperature detection module 19-3, the fourth temperature detection module 19-4, the first fluid delivery module 21, the second fluid delivery module 22, the fifth water valve 23, and the sixth water valve 24.

[0069] The modules are connected by pipelines. A first water valve 15 is installed on the pipeline between the first water outlet O4 of the three-way valve 14 and the solar heating sub-module 12-1; a second water valve 16 is installed on the pipeline between the solar heating sub-module 12-1 and the unit heating sub-module 12-2; a third water valve 17 is installed on the first water inlet of the heating container 12; and a fourth water valve 18 is installed on the first water inlet of the insulation container 13. The water valves are used to control the flow status of the pipelines.

[0070] The heating container 12 is equipped with a first temperature detection module 19-1, the insulation container 13 is equipped with a second temperature detection module 19-2, and the water outlet of the unit heating sub-module 11-2 is O. 2-1 A third temperature detection module 19-3 is provided, and a fourth temperature detection module 19-4 is provided at the water outlet O1 of the heating module.

[0071] A first fluid delivery module 21 is installed on the pipeline between the first water outlet O2 of the heating container 12 and the water inlet I5 of the three-way valve 14; the first fluid delivery module 21 is used to deliver the water resources in the heating container 12 to the water inlet I5 of the three-way valve 14.

[0072] A second fluid delivery module 22 is installed on the pipeline between the first water outlet O3 of the heat-insulating container 13 and the water inlet I5 of the three-way valve 14; the second fluid delivery module 22 is used to deliver the water resources in the heat-insulating container 13 to the water inlet I5 of the three-way valve 14.

[0073] The first water outlet O2 of the heating container 12 and the first water outlet O3 of the insulation container are connected by a pipeline equipped with a fifth water valve 23; the second water outlet O5 of the heating container 12 and the second water inlet I6 of the insulation container are connected by a pipeline equipped with a sixth water valve 24.

[0074] It should be noted that the heating priority of the solar heating sub-module 11-1 is higher than that of the generator heating sub-module 11-2, and the heating priority of the generator heating sub-module 11-2 is higher than that of the electric heating sub-module 11-3.

[0075] In addition, the system also includes: a circulating water supply pipeline 25, the second water outlet O6 of the heat preservation container 13 is connected to the water inlet I7 of the circulating water supply pipeline 25, the first water outlet O7 of the circulating water supply pipeline 25 is connected to the water outlet 26, and the second water outlet O8 of the circulating water supply pipeline 25 is connected to the third water inlet I8 of the heat preservation container 13. A third fluid delivery module 27 and a seventh water valve 28 are installed on the circulating water supply pipeline; the third fluid delivery module 27 is used to deliver the water resources in the insulated container 13 to the water-using end 26.

[0076] The aforementioned first water valve 15 is used to control the flow of water into the solar heating sub-module 11-1. It is closed when solar heating is not required or when this branch is under maintenance, in order to achieve heat source isolation and system protection.

[0077] The aforementioned second water valve 16 is used to control the on / off connection of the series pipeline between the solar heating sub-module 11-1 and the unit heating sub-module 11-2. When solar heating is sufficient to meet the demand or the unit heating sub-module 11-2 needs to operate independently, this valve can be closed to decouple the branch circuit function.

[0078] The aforementioned third water valve 17 is located at the first water inlet I2 of the heating container 12 and is used to control whether the hot water heated by the heating module 11 flows back to the heating container 12.

[0079] The aforementioned fourth water valve 18 is located at the first water inlet I3 of the heat preservation container 13 and is used to control whether the hot water heated by the heating module 11 flows into the heat preservation container 13.

[0080] The aforementioned first temperature detection module 19-1 is used to detect the water temperature inside the heating container 12 in real time, so as to determine whether it is necessary to start heating, add water, or enter sleep mode for the heating container 12.

[0081] The second temperature detection module 19-2 is used to detect the water temperature inside the insulation container 13 in real time, so as to determine whether the insulation container 13 needs to be reheated and whether the water supply temperature of the user terminal 26 meets the standard.

[0082] The aforementioned third temperature detection module 19-3 is used to detect the water outlet O of the heating sub-module 11-2 of the unit. 2-1 The water temperature is directly monitored to assess the real-time heating effect of the heating sub-module 11-2 of the unit, providing a basis for determining whether the electric heating sub-module 11-3 needs to be activated or the operating strategy needs to be adjusted.

[0083] The aforementioned fourth temperature detection module 19-4 is used to detect the water temperature at the main outlet O1 of the heating module 11, and to detect the final output result after the various heating sub-modules work together, so as to verify whether the heating has reached the system set target, and to serve as important feedback for controlling the three-way valve 14 and subsequent water circuit distribution.

[0084] The aforementioned first fluid delivery module 21 can be a water pump, used to provide power to actively deliver water from the heating container 12 to the heating module 11, ensuring the establishment and maintenance of the heating cycle.

[0085] The aforementioned second fluid delivery module 22 can be a water pump, used to provide power to actively deliver water from the insulation container 13 to the heating module 11, ensuring the establishment and maintenance of a direct heat replenishment cycle for the insulation container 13. The aforementioned fifth water valve 23 is used to control the connection pipeline between the water outlets of the heating container 12 and the insulation container 13. When this valve is opened, the water outlets of the two containers can be mixed before entering the heating module 11, thus achieving a mixed heating mode.

[0086] The aforementioned sixth water valve 24 is used to control the bypass channel for water replenishment from the heating container 12 directly to the insulation container 13. When opened, it allows the heated hot water in the heating container 12 to flow directly into the insulation container 13 without passing through the heating module 11, thereby achieving rapid water replenishment and improving efficiency.

[0087] The aforementioned circulating water supply pipeline 25 is used to establish a circulation loop between the insulation container 13 and the water-using end 26. Its purpose is to maintain the water temperature in the pipeline near the water-using end 26, reduce the time users have to wait for hot water after turning on the tap, and achieve "instant hot water".

[0088] The water-using terminal 26 mentioned above refers to the hot water usage terminal of the system, such as a shower head, kitchen faucet, etc., and this application embodiment does not limit this.

[0089] The aforementioned third fluid delivery module 27 can be a circulation pump, installed on the circulating water supply pipeline 25, to provide power for the circulation of hot water in the pipeline and ensure the normal operation of the circulation loop.

[0090] The aforementioned seventh water valve 28 is installed on the circulating water supply pipeline 25 and is used to control the on / off state of the circulation loop. This valve can be closed to save energy when circulation is not required or system maintenance is not needed.

[0091] In addition, overflow pipes can be provided in the heating container 12 and the insulation container 13 so that when the amount of water stored therein reaches the capacity limit, the excess water can flow out through the overflow pipes.

[0092] like Figure 4 The diagram shown is a schematic representation of the implementation flow of a water supply system control method provided in this application embodiment. This method, applied to the aforementioned water supply system, may specifically include the following steps: S401, collects the first water resource parameters of the water resources in the heating container and the second water resource parameters of the water resources in the insulation container in the water supply system.

[0093] The above-mentioned water supply system can provide Figure 3The water supply system 30 is used to realize the intelligent preparation, storage, circulation and supply of hot water.

[0094] The above-mentioned heating container can be Figure 3 The heating container 12 is used to receive external water sources and to heat the water sources initially or continuously. It can also be used as a direct water source to supplement hot water to the heat preservation container 13.

[0095] The aforementioned first water resource parameter is used to characterize the real-time state of the water in the heating container 12, and may include the current water level (first water level, such as 5L) and the current temperature of the stored water (first temperature, such as 25℃). The first water level is used to determine whether it is necessary to replenish the water in the heating container, and the first temperature is used to determine whether it is necessary to start the heating program.

[0096] The above-mentioned insulated containers can be Figure 3 The insulated container 13 is used to store heated hot water, and the insulation layer inside the container can reduce the heat loss of the heated hot water to ensure a stable supply of hot water to the water user.

[0097] The aforementioned second water resource parameter is used to characterize the real-time state of the water inside the insulated container 13, and may include the current water level (second water level, e.g., 5L) and the current temperature of the stored water (second temperature, e.g., 25℃). The first water level is used to determine whether the current amount of water stored in the insulated container is sufficient, and the first temperature is used to determine whether the stored hot water needs to be replenished.

[0098] In this embodiment, a first water resource parameter and a second water resource parameter of the water in the heating container and the insulation container of the water supply system can be collected. Specifically, the first water resource parameter can be collected using a first water level sensor and a first temperature detection module installed in the heating container. The second water resource parameter can be collected using a second water level sensor and a second temperature detection module installed in the insulation container. When collecting the first water resource parameter of the water in the heating container and the second water resource parameter of the water in the insulation container of the water supply system, periodic sampling can be performed according to a preset sampling period (e.g., 10 seconds, 20 seconds).

[0099] S402, determine the current operating mode of the water supply system based on the first water resource parameter and / or the second water resource parameter.

[0100] In this embodiment, the current operating mode of the water supply system can be determined based on a first water resource parameter and / or a second water resource parameter. The current operating mode of the water supply system can be categorized into a heating container operating mode, an insulation container operating mode, and a mixed operating mode of heating and insulation containers.

[0101] The above-mentioned heating container operation mode refers to the water supply system's control objective being primarily focused on the operation mode of the heating container.

[0102] The above-mentioned operating mode of the insulated container refers to the operating mode in which the control objective of the water supply system is mainly focused on the insulated container 13.

[0103] The aforementioned mixed operation mode of heating and insulation containers refers to a water supply system control operation mode that involves the coordinated operation of both heating and insulation containers.

[0104] Specifically, determining the current operating mode of the water supply system based on the first water resource parameter and / or the second water resource parameter may include: determining the current operating mode of the water supply system for the heating container based on the first water resource parameter; or, determining the current operating mode of the water supply system for the insulation container based on the first water resource parameter and the second water resource parameter; or, determining the mixed operating mode of the water supply system for the heating container and the insulation container based on the first water resource parameter and the second water resource parameter; and determining the heating container operating mode, the insulation container operating mode, or the mixed operating mode as the current operating mode of the water supply system.

[0105] For details on how to determine the current operating mode of the heating container in the water supply system based on the first water resource parameter, please refer to the following: Figure 5 Steps S502~S503.

[0106] For details on how to determine the current operating mode of the insulated container in the water supply system based on the first and second water resource parameters, please refer to the following: Figure 6 Step S602.

[0107] As for how to determine the mixed operation mode of the water supply system for heating and insulation containers based on the first and second water resource parameters, please refer to the following: Figure 7 Steps S702~S703.

[0108] S403 controls the operating status of the heating module in the water supply system based on the operating mode.

[0109] In this embodiment, the operating mode determined by the above steps can control the operating state of the heating module in the water supply system. The operating state of the heating module corresponds to the operating mode. If the current operating mode of the water supply system is the heating container operating mode, the operating state of the heating module is to heat or replenish water to the heating container; if the current operating mode of the water supply system is the insulation container operating mode, the operating state of the heating module is to heat the insulation container; if the current operating mode of the water supply system is the mixed operating mode, the operating state of the heating module is to transfer hot water between the heating container and the insulation container or enter a dormant state.

[0110] Based on the above description of the technical solution provided in the embodiments of this application, a first water resource parameter and a second water resource parameter are collected from the water resources in the heating container and the insulation container of the water supply system. The current operating mode of the water supply system is determined based on the first and / or second water resource parameters. The operating state of the heating module within the water supply system is controlled based on the operating mode. By determining the current operating mode of the water supply system based on the first and / or second water resource parameters, and controlling the operating state of the heating module within the water supply system, adaptive, intelligent, and refined control of the water supply system can be achieved. This allows the water supply system to proactively adapt to changes in external conditions (such as sunlight, water temperature drop, and water consumption) and internal state changes, dynamically switching operating modes and optimizing energy distribution. While ensuring a stable supply of hot water that meets temperature requirements, it maximizes the use of efficient and clean energy (solar energy) and reduces the consumption of high-grade electrical energy. This fundamentally solves the technical problems of long heat transfer paths, high heat loss, and low energy utilization in traditional dual-tank systems from the control logic level, achieving the goals of energy saving, high efficiency, and reliable operation.

[0111] like Figure 5 The diagram shown is a schematic representation of the implementation flow of another water supply system control method provided in this application embodiment. This method, applied to the aforementioned water supply system, may specifically include the following steps: S501, collect the first water resource parameters of the water resources in the heating container and the second water resource parameters of the water resources in the insulation container in the water supply system. The first water resource parameters include the first water level and the first temperature of the water resources in the heating container.

[0112] In this embodiment of the application, a first water resource parameter of the water resource in the heating container and a second water resource parameter of the water resource in the heat preservation container in the water supply system can be collected. The first water resource parameter includes the first water level and the first temperature of the water resource in the heating container.

[0113] The first water level in the aforementioned heating container refers to the water level in the heating container (corresponding to...). Figure 3 The instantaneous water level or volume in the heating container 12) is measured, such as 5L. This can be used to determine whether the water level in the container is within a range suitable for safe and effective heating circulation.

[0114] The first temperature of the water resources in the aforementioned heating container refers to the temperature of the heating container (corresponding to...). Figure 3 The instantaneous average temperature of the water in the heating container 12) is used to assess whether the preset heating target has been reached or to determine whether the heating program needs to be started.

[0115] S502, if it is determined that the first water level is less than the preset first minimum water level threshold, the operating mode of the heating container is determined to be the first water replenishment mode for the heating container.

[0116] In this embodiment, when the first water level is determined to be lower than a preset first minimum water level threshold, the heating container's operating mode is determined to be a first water replenishment mode. The preset first minimum water level threshold is a minimum safe water level, such as 2L, set to ensure the heating container can normally start the circulation pump (i.e., the first fluid delivery module 21) and avoid the risk of dry burning. The first water replenishment mode prioritizes ensuring the basic water volume of the heating container. In this mode, heating is temporarily suspended, and water is primarily stored in the heating container to ensure that the water volume reaches above the preset first minimum water level threshold.

[0117] Specifically, when the heating container is in the first water replenishment mode, the water supply system will close the water outlet passage from the heating container 12 to the heating module 11 (e.g., control the first fluid delivery module 21 to stop working) in this mode, and at the same time open the external water source inlet valve of the second water inlet I4 of the heating container 12 to introduce external cold water until the first water level recovers to a level higher than the first minimum water level threshold. Meanwhile, the first water level is controlled to be between the first minimum water level threshold and the first maximum water level threshold.

[0118] S503, when it is determined that the first water level is greater than the preset first maximum water level threshold and the first temperature is less than the preset first temperature threshold, the operating mode of the heating container is determined to be the first heating mode of the heating container.

[0119] In this embodiment, when it is determined that the first water level is greater than a preset first maximum water level threshold and the first temperature is less than a preset first temperature threshold, the operating mode of the heating container is determined to be a first heating mode for the heating container. The preset first temperature threshold is a pre-set high water level line for the heating container, used to determine whether the heating container is full of water and to prevent overflow caused by continued water replenishment during the heating process.

[0120] Specifically, when the heating container is in the first heating mode, the water supply system will start the heating process in this mode to heat only the water in the heating container, thereby heating the water in the heating container to above the first temperature threshold.

[0121] S504, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. The outlet end of the heating module is equipped with a three-way valve. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. When the operating mode is the first heating mode, the water resources of the heating container are controlled to flow into the inlet end of the three-way valve through the first outlet end of the heating container, and the first inlet end of the heating container is controlled to open.

[0122] In this embodiment, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. A three-way valve is installed at the outlet of the heating module. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. In the first heating mode, the water resources of the heating container are controlled to flow into the inlet of the three-way valve through the first outlet of the heating container, and the first inlet of the heating container is controlled to open. This forms a closed heating loop from the heating container, the heating module, and back to the heating container.

[0123] S505, the first water outlet of the three-way valve connected to the electric heating sub-module is closed, and the second water outlet of the three-way valve connected to the solar heating sub-module is opened.

[0124] In this embodiment, the first water outlet connected to the three-way valve and the electric heating sub-module is closed, and the second water outlet connected to the three-way valve and the solar heating sub-module is opened. At this time, the water flow from the heating container is forced to be entirely directed to the solar heating sub-module for heating.

[0125] S506 controls the operation of the solar heating sub-module for a first preset duration, and controls the unit's heating sub-module and electric heating sub-module to stop operating.

[0126] In this embodiment, the solar heating sub-module is controlled to operate for a first preset duration, and the unit's heating sub-module and electric heating sub-module are controlled to stop operating. The preset first duration is a pre-set operating time for the solar heating sub-module, such as 30 minutes, or an empirical value set based on the water supply system capacity and current sunshine conditions. Within the preset first duration, the solar heating sub-module independently heats the water flow from the heating container.

[0127] S507, after a first preset time period, determines whether the first outlet water temperature corresponding to the outlet water end of the unit's heating sub-module is greater than the first temperature threshold.

[0128] In this embodiment, after a first preset time period, it is determined whether the first outlet water temperature corresponding to the outlet end of the unit's heating sub-module is greater than a first temperature threshold. This first outlet water temperature can be determined using a third temperature detection module.

[0129] S508, when it is determined that the first outlet water temperature is less than or equal to the first temperature threshold, the heating sub-module of the unit is controlled to start for a second preset duration.

[0130] In this embodiment, when the first outlet water temperature is determined to be less than or equal to a first temperature threshold, the unit's heating sub-module is controlled to operate for a second preset duration. The second preset duration refers to a set auxiliary heating operation time for the unit's heating sub-module (heat pump), for example, 15 minutes. If the first outlet water temperature is less than or equal to the first temperature threshold, it indicates that the solar heating sub-module alone has failed to meet the heating standard, and the water supply system will automatically activate the second most energy-efficient heat pump (i.e., the unit's heating sub-module) to provide supplementary heating.

[0131] S509, after the second preset time period, if it is determined that the first outlet water temperature corresponding to the outlet water end of the unit heating sub-module is still less than or equal to the first temperature threshold, then the first outlet water end of the three-way valve is opened, and the electric heating sub-module is opened.

[0132] In this embodiment, after a second preset time period, if it is determined that the first outlet water temperature corresponding to the outlet of the unit heating sub-module is still less than or equal to the first temperature threshold, it indicates that the heating capacity of the unit heating sub-module and the solar heating sub-module is still insufficient. At this time, it is necessary to control the first outlet of the three-way valve to open and control the electric heating sub-module to open. Thus, while maintaining a portion of the water flow through the unit heating sub-module and the solar heating sub-module, another portion of the water flow is opened to enter the electric heating sub-module for heating. At this time, the water supply system enters a multi-heat source (i.e., unit heating sub-module, solar heating sub-module, and electric heating sub-module) collaborative working state to improve the total heating power.

[0133] S510, after a third preset time period, if it is determined that the water temperature at the outlet of the heating module is less than or equal to the first temperature threshold, then the opening ratio of the first and second outlets of the three-way valve is increased.

[0134] In this embodiment, after a third preset time period, if it is determined that the outlet water temperature of the heating module is less than or equal to the first temperature threshold, the opening ratio of the first and second outlets of the three-way valve is increased. When the outlet water temperature of the heating module is less than or equal to the first temperature threshold, it means that even if all heat sources (i.e., the unit heating sub-module, the solar heating sub-module, and the electric heating sub-module) heat the water in the heating container simultaneously, the final output hot water temperature still cannot reach the first temperature threshold. At this time, increasing the opening ratio of the first and second outlets of the three-way valve can allow a larger proportion of the water flow to be allocated to the electric heating branch (i.e., the electric heating sub-module), which usually heats faster, thereby increasing the overall instantaneous heating power of the system and approaching and finally reaching the first temperature threshold more quickly.

[0135] For example, the initial flow split ratio of the three-way valve is 70%:30% for the solar / heat pump branch (i.e., the branch where the unit heating sub-module and the solar heating sub-module are located): the electric heating branch (i.e., the branch where the electric heating sub-module is located). If the effect is not good, it can be adjusted to 50%:50% or even higher to make the water flow biased towards the electric heating branch to ensure the heating target is achieved.

[0136] like Figure 6 The diagram shown is a schematic representation of the implementation flow of another water supply system control method provided in this application embodiment. This method, applied to the aforementioned water supply system, may specifically include the following steps: S601, collect the first water resource parameters of the water resources in the heating container and the second water resource parameters of the water resources in the insulation container in the water supply system. The first water resource parameters include the first water level and the first temperature of the water in the heating container, and the second water resource parameters include the second water level and the second temperature of the water in the insulation container.

[0137] In this embodiment of the application, first water resource parameters of water resources in the heating container and second water resource parameters of water resources in the insulation container are collected in the water supply system. The first water resource parameters include a first water level and a first temperature in the heating container, and the second water resource parameters include a second water level and a second temperature in the insulation container. The second water level in the insulation container refers to the water level in the insulation container (corresponding to...). Figure 3 The insulated container 13) refers to the immediate water level or capacity (e.g., 2L) stored inside. This is used to determine if there is sufficient usable hot water in the insulated container, to decide whether water needs to be added from the heating container to the insulated container, or whether direct circulation heating of the water in the insulated container can be initiated. The second temperature of the water level in the insulated container refers to the temperature of the insulated container (corresponding to...). Figure 3 The insulated container 13) contains the instantaneous average temperature of the water stored inside (e.g., 15°C). This is used to assess whether the actual temperature of the hot water in the insulated container meets the user's requirements or the system's set insulation target.

[0138] S602, when it is determined that the second temperature is less than or equal to a preset second temperature threshold, the second water level is greater than a preset second minimum water level threshold, and the first temperature is less than or equal to the second temperature, the operating mode of the heat preservation container is determined to be the second heating mode for the heat preservation container.

[0139] In this embodiment of the application, when it is determined that the second temperature is less than or equal to a preset second temperature threshold, the second water level is greater than a preset second minimum water level threshold, and the first temperature is less than or equal to the second temperature, the operating mode of the heat preservation container is determined to be the second heating mode for the heat preservation container.

[0140] The second heating mode refers to heating only the water in the insulated container. The second temperature threshold is the minimum acceptable water temperature or target insulation temperature set for the insulated container (e.g., 45°C); heating must be activated if the temperature falls below this value. The second minimum water level threshold is the minimum safe water volume required for the insulated container to initiate an independent heating cycle, ensuring sufficient water for effective circulation (e.g., 1L). If the first temperature is less than or equal to the second temperature, it indicates that the water temperature in the heating container is not higher than the water temperature in the insulated container. In this case, only the water in the insulated container needs to be heated, without heating the heating container itself. This avoids the problem of low-temperature water from the heating container mixing in or affecting the heating efficiency of the insulated container due to misoperation or abnormalities when heating the heating container, ensuring that heating resources are concentrated on raising the water temperature in the insulated container.

[0141] S603, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. The outlet of the heating module is equipped with a three-way valve. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. When the operating mode is the second heating mode, the water resources of the insulation container are controlled to flow into the inlet of the three-way valve through the first outlet of the insulation container, and the first inlet of the insulation container is controlled to open.

[0142] In this embodiment, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. A three-way valve is provided at the outlet of the heating module. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. When the operating mode is the second heating mode, the water resources of the insulation container are controlled to flow into the inlet of the three-way valve through the first outlet of the insulation container, and the first inlet of the insulation container is controlled to open, so as to establish an independent closed-loop heating water circuit for the insulation container, ensuring that the water in the insulation container can be extracted, heated and transported back to the original container.

[0143] S604 controls the first water outlet of the three-way valve connected to the electric heating sub-module to close, and controls the second water outlet of the three-way valve connected to the solar heating sub-module to open.

[0144] In this embodiment, the first water outlet connected to the electric heating sub-module is closed, and the second water outlet connected to the solar heating sub-module is opened.

[0145] S605 controls the operation of the solar heating sub-module for a first preset duration, and controls the unit's heating sub-module and electric heating sub-module to stop operating.

[0146] In this embodiment, the solar heating sub-module is controlled to operate for a first preset duration, and the unit heating sub-module and electric heating sub-module are controlled to stop operating. The first preset duration refers to a time (e.g., 20 minutes) pre-set based on system capacity (e.g., the capacity of the insulated container), historical sunshine data (light intensity), and heating experience. This time allows the solar heating sub-module sufficient time to operate independently to assess whether it can independently raise the water temperature of the insulated container to above a second temperature threshold under current conditions.

[0147] S606, after a first preset time period, determines whether the second outlet water temperature corresponding to the outlet water end of the unit's heating sub-module is greater than the second temperature threshold.

[0148] In this embodiment of the application, after a first preset time period, it is determined whether the second outlet water temperature corresponding to the outlet end of the unit heating sub-module is greater than the second temperature threshold.

[0149] S607, when it is determined that the second outlet water temperature is less than or equal to the second temperature threshold, the heating sub-module of the unit is controlled to start for a second preset time.

[0150] In this embodiment of the application, when it is determined that the second outlet water temperature is less than or equal to the second temperature threshold, the heating sub-module of the control unit is activated for a second preset duration.

[0151] S608, after a second preset time period, if it is determined that the second outlet water temperature corresponding to the outlet water end of the unit's heating sub-module is still less than or equal to the second temperature threshold, then the first outlet water end of the three-way valve is opened, and the electric heating sub-module is opened.

[0152] In this embodiment of the application, after a second preset time period, if it is determined that the second outlet water temperature corresponding to the outlet water end of the unit heating sub-module is still less than or equal to the second temperature threshold, then the first outlet water end of the three-way valve is opened, and the electric heating sub-module is opened.

[0153] S609, after a third preset time period, if it is determined that the outlet water temperature of the heating module is less than or equal to the second temperature threshold, then the opening ratio of the first outlet and the second outlet of the three-way valve is increased.

[0154] In this embodiment of the application, after a third preset time period, if it is determined that the outlet water temperature of the heating module is less than or equal to the second temperature threshold, the opening ratio of the first outlet water end and the second outlet water end of the three-way valve is increased.

[0155] Specifically, after the preceding steps and stable operation for a third preset period, the system will determine whether the outlet water temperature of the heating module is less than or equal to the second temperature threshold based on the detection results of the fourth temperature detection module. If the outlet water temperature is less than or equal to the second temperature threshold, it indicates that the current total heating power still needs optimization. Therefore, the proportion of water flowing to the electric heating branch (first outlet water end) can be increased, while the proportion flowing to the solar series branch (second outlet water end) can be reduced accordingly. This will rapidly increase the total heating power of the system, thereby enabling the final outlet water temperature to reach the second temperature threshold more quickly.

[0156] like Figure 7 The diagram shown is a schematic representation of the implementation flow of another water supply system control method provided in this application embodiment. This method is applied to the aforementioned water supply system and may specifically include the following steps: S701, collects the first water resource parameters of the water resources in the heating container and the second water resource parameters of the water resources in the insulation container in the water supply system. The first water resource parameters include the first water level and the first temperature of the water in the heating container, and the second water resource parameters include the second water level and the second temperature of the water in the insulation container.

[0157] In this embodiment of the application, this step is similar to step S601 above, and will not be described in detail here.

[0158] S702, when it is determined that the second temperature is less than or equal to the second temperature threshold and the first temperature is greater than the second temperature, or when it is determined that the second temperature is greater than the second temperature threshold and the second water level is less than the preset second minimum water level threshold, the mixed operation mode is determined to be the second water replenishment mode of replenishing water to the heat preservation container by heating the container.

[0159] In this application embodiment, when it is determined that the second temperature is less than or equal to the second temperature threshold and the first temperature is greater than the second temperature, or when it is determined that the second temperature is greater than the second temperature threshold and the second water level is less than the preset second minimum water level threshold, the mixed operation mode is determined to be the second water replenishment mode of replenishing water to the heat preservation container by heating the container.

[0160] When the water temperature in the insulated container (second temperature) is lower than the target (second temperature threshold), and the water temperature in the heating container (first temperature) is higher than the water temperature in the insulated container, the relatively hotter water source in the heating container can be used to replenish the insulated container with hot water through the heating module (which can selectively provide auxiliary heating) to quickly increase its water temperature and volume. Alternatively, when the water temperature in the insulated container meets the requirements (second temperature > second temperature threshold), but its water storage volume is insufficient (second water level < second minimum water level threshold), the insulated container needs to be replenished with water from the heating container to maintain the available water volume. Since the temperature of the replenishing water source (water in the heating container) may be lower than the target temperature of the insulated container, the heating module can be activated during the replenishment process to heat the water flow, ensuring that the replenished water does not affect the overall water temperature of the insulated container.

[0161] S703, when it is determined that the second temperature is greater than the second temperature threshold, the second water level is greater than the second minimum water level threshold, the first water level is greater than the preset first minimum water level threshold, and the first temperature is greater than the preset first temperature threshold, the mixed operation mode is determined to be the hibernation mode.

[0162] In this embodiment, when it is determined that the second temperature is greater than the second temperature threshold, the second water level is greater than the second minimum water level threshold, the first water level is greater than the preset first minimum water level threshold, and the first temperature is greater than the preset first temperature threshold, the hybrid operation mode is determined to be a dormant mode. That is, when the water temperature and volume in the insulation container are sufficient, and the water volume and temperature in the heating container are also in good condition, it indicates that there is no immediate need for heating or water replenishment. At this time, most of the execution components (such as the heating module) stop operating, and only necessary parameter monitoring is maintained (such as the first temperature detection module and the second temperature detection module detecting the water temperature).

[0163] S704, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. The outlet end of the heating module is equipped with a three-way valve. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. When the operating mode is the second water replenishment mode, the water resources of the heating container are controlled to flow into the inlet end of the three-way valve through the first outlet end of the heating container, the first inlet end of the heating container is controlled to be closed, and the first inlet end of the insulation container is controlled to be opened.

[0164] In this embodiment, the heating module includes a solar heating sub-module, a generator heating sub-module, and an electric heating sub-module. A three-way valve is provided at the water outlet of the heating module. The solar heating sub-module and the generator heating sub-module are connected in series, and the solar heating sub-module and the electric heating sub-module are connected in parallel. When the operating mode is the second water replenishment mode, the water resources of the heating container are controlled to flow into the water inlet of the three-way valve through the first water outlet of the heating container, the first water inlet of the heating container is controlled to be closed, and the first water inlet of the insulation container is controlled to be opened, thereby forming a flow path through the heating container, the heating module, and the insulation container.

[0165] S705 controls the first water outlet of the three-way valve connected to the electric heating sub-module to close, and controls the second water outlet of the three-way valve connected to the solar heating sub-module to open.

[0166] In this embodiment, the first water outlet connected to the electric heating sub-module is closed, and the second water outlet connected to the solar heating sub-module is opened.

[0167] S706 controls the operation of the solar heating sub-module for a first preset duration, and controls the shutdown of the unit's heating sub-module and electric heating sub-module.

[0168] In this embodiment, the solar heating submodule is controlled to operate for a first preset time, and the unit heating submodule and electric heating submodule are controlled to stop operating. During the first preset time, the solar heating submodule can heat the water flowing from the heating container into the insulation container.

[0169] S707, after a first preset time period, determines whether the third outlet water temperature corresponding to the outlet water end of the unit's heating sub-module is greater than the second temperature threshold.

[0170] In this embodiment, after a first preset time period, it is determined whether the third outlet water temperature corresponding to the outlet end of the unit's heating sub-module is greater than the second temperature threshold. Specifically, the third temperature detection module can be used to detect the temperature of the water at the outlet end of the unit's heating sub-module, thereby obtaining the third outlet water temperature corresponding to the outlet end of the unit's heating sub-module.

[0171] S708, when it is determined that the third outlet water temperature is less than or equal to the second temperature threshold, controls the heating sub-module of the unit to start for the second preset time.

[0172] In this embodiment of the application, when it is determined that the third outlet water temperature is less than or equal to the second temperature threshold, the heating sub-module of the control unit is activated for a second preset duration.

[0173] S709, after the second preset time period, if it is determined that the third outlet water temperature corresponding to the outlet water end of the unit heating sub-module is still less than or equal to the second temperature threshold, then the first outlet water end of the three-way valve is opened, and the electric heating sub-module is opened.

[0174] In this embodiment of the application, after a second preset time period, if it is determined that the third outlet water temperature corresponding to the outlet water end of the unit heating sub-module is still less than or equal to the second temperature threshold, then the first outlet water end of the three-way valve is opened, and the electric heating sub-module is opened.

[0175] S710, after a third preset time period, if it is determined that the outlet water temperature of the heating module is less than or equal to the second temperature threshold, then the opening ratio of the first outlet and the second outlet of the three-way valve is increased.

[0176] In this embodiment of the application, after a third preset time period, if it is determined that the outlet water temperature of the heating module is less than or equal to the second temperature threshold, the opening ratio of the first outlet water end and the second outlet water end of the three-way valve is increased.

[0177] Specifically, after the preceding steps and stable operation for a third preset period, the system will determine whether the outlet water temperature of the heating module is less than or equal to the second temperature threshold based on the detection results of the fourth temperature detection module. If the outlet water temperature is less than or equal to the second temperature threshold, it indicates that the current total heating power still needs optimization. Therefore, the proportion of water flowing to the electric heating branch (first outlet water end) can be increased, while the proportion flowing to the solar series branch (second outlet water end) can be reduced accordingly. This will rapidly increase the total heating power of the system, thereby enabling the final outlet water temperature to reach the second temperature threshold more quickly.

[0178] Furthermore, the control method of the water supply system provided in this application embodiment is illustrated with specific examples: like Figure 8 The diagram shown is a structural schematic of another water supply system provided in this application embodiment, which may specifically include: a heating water tank, an insulated water tank, a pressure sensor, a heat pump unit, a solar panel, and an electric auxiliary heater.

[0179] Among them, F1~F9 are valves used to control the on / off state of the pipeline; B-1 is a transfer pump used to transfer water flowing through the heating water tank; B-2 is a transfer pump used to transfer water flowing through the insulated water tank; and B-3 is a transfer pump used to transfer water flowing through the insulated water tank to the user side. Electric auxiliary heating is used to electrically heat the water source, and solar panels are used to heat the water source using solar energy. A heat pump unit is used to heat the water source. T3 is a temperature sensor used to detect the water temperature after flowing through branch b; T4 is a temperature sensor used to detect the water temperature flowing into the heating water tank or insulated water tank; and T5 is a temperature sensor used to detect the water temperature flowing into the insulated water tank. An overflow pipe is used to drain excess water when the water volume in the heating water tank or insulated water tank exceeds the preset volume.

[0180] like Figure 9 The diagram shown is a schematic representation of the implementation flow of a water replenishment control method for a heating container provided in this application embodiment, which may specifically include: Step 1, initial stage: detect the water level h1 in the heating water tank, set the minimum water level in the heating water tank to H1min, and the maximum water level in the heating water tank to H1max.

[0181] Step 2: Determine whether the water level h1 in the heating water tank is less than or equal to the lowest water level H1min in the heating water tank. If the water level h1 in the heating water tank is less than or equal to the lowest water level H1min in the heating water tank, the water supply valve in the heating water tank will be opened to replenish the water supply to the heating water tank.

[0182] Step 3: Determine if the water level h1 in the heating tank is greater than or equal to the maximum water level H1max in the heating tank. If the water level h1 is greater than or equal to the maximum water level H1max, it means that there is enough water in the heating tank. At this time, the water supply valve of the heating tank can be closed (i.e., Figure 9 (F3), and at the same time, steps 1 to 3 can be executed periodically; if the water level h1 in the heating water tank is less than the maximum water level H1max in the heating water tank, water will continue to be added, and the water supply valve of the heating water tank will be opened until h1 is greater than or equal to H1max, and then the water supply valve of the heating water tank will be closed. At the same time, steps 1 to 3 can be executed periodically.

[0183] like Figure 10 The diagram shown is a schematic representation of the implementation flow of a heating control method for a water supply system provided in this application embodiment, which may specifically include: Step 1: Set the heating water tank temperature T1 and detect the heating water tank temperature t1; set the insulation water tank temperature T2 and detect the insulation water tank temperature t2; install temperature sensor T3 at the unit outlet to detect temperature t3; install temperature sensor T4 at the mixing point with the electric auxiliary heating water to detect the mixing point temperature t4; set the unit outlet temperature T3 and the mixing temperature T4; T3 = T1, T4 = T1; the proportional three-way regulating valve F6 has three connecting circuits: a, b, and c, as detailed below. Figure 8As shown.

[0184] Step 2: Determine if the heating water tank temperature t1 is lower than the set heating water tank temperature T1. If the heating water tank temperature t1 is lower than the set heating water tank temperature T1, then open F7, F5, and F6 (water flows through path ab, not path c), open F1 and B-1, close F2 and B-2, shut down the heat pump unit (only water is connected, no heating), and shut down the electric auxiliary heating; prioritize solar panel heating, shut down the heat pump unit and the electric auxiliary heating, and proceed to step 4; if the heating water tank temperature t1 is not lower than the set heating water tank temperature T1, then proceed to step 3.

[0185] Step 3: Turn off F1, turn on F2, turn on F6, water flows through circuit ac. Turn off F5 and F7, turn on B-1, turn off B-2. Water does not pass through the solar panel or the heat pump unit. Electric auxiliary heating is off. When the temperature reaches the required level, water is pumped into the insulation tank until the water level H2max is reached. At this point, the insulation logic can be activated. Figure 11 The steps are shown.

[0186] Step 4: Determine whether t3 is greater than or equal to the set unit outlet water temperature T3 (at this time, t3 is the solar water outlet temperature after heating for a period of time, which is adjustable, 10 minutes or 15 minutes). If t3 is greater than or equal to the set unit outlet water temperature T3, then proceed to step 3; if t3 is less than the set unit outlet water temperature T3, then proceed to step 5.

[0187] Step 5: Turn on F7, F5, and F6 (follow path ab, not path c), turn on F1, turn off F2, turn on B-1, turn off B-2, the heat pump unit starts heating, and the electric auxiliary heater is turned off; the solar panel preheats, then the heat pump unit heats up, and proceed to step 6.

[0188] Step 6: Determine if t3 is greater than or equal to the set unit outlet water temperature T3 (at this time, T3 is the outlet water temperature after heating for a period of time by solar energy + unit heating, which is adjustable, 10 minutes or 15 minutes). If yes, proceed to step 3; if no, proceed to step 7.

[0189] Step 7: Turn on F7, F5, and F6 (water flows through ab and c channels; adjust the opening of F6, for example, to open b channel at 90% water volume and c channel at 10% water volume, the percentage is adjustable), turn on F1, turn off F2, turn on B-1, turn off B-2 to start the unit in heating mode, and turn on the electric auxiliary heating; the water enters the solar preheating system, and then enters the unit to heat up. Adjust the flow rate of the two parallel channels, use the parallel electric auxiliary heating to increase a portion of the water volume and temperature, and after mixing the water to reach the desired temperature, proceed to step 8.

[0190] Step 8: Determine if t4 is greater than or equal to the set temperature T4 at the mixing point. If yes, proceed to step 3; otherwise, proceed to step 9.

[0191] Step 9: Increase the opening of F6 in channel c and decrease the opening of channel b. The flow rate in channel c will increase and the flow rate in channel b will decrease (the opening is adjustable, for example, adjust it to 80% water flow in channel b and 20% water flow in channel C, the percentage is adjustable). Then execute step 8.

[0192] like Figure 11 The diagram shown is a schematic representation of the implementation process of a water supply system heat preservation control method provided in this application embodiment, which may specifically include: Step 1: When the insulated water tank reaches the set temperature T2, the insulation needs to be turned on. Detect the actual temperature t2 of the insulated water tank and the temperature t1 of the heating water tank. Detect the water level h2 of the insulated water tank, set the maximum water level H2max and the minimum water level H2min of the insulated water tank. Detect the liquid level h1 of the heating water tank, set the minimum liquid level H1min and the maximum water level H1max of the heating water tank.

[0193] Step 2: Determine if the actual temperature t2 of the insulated water tank is less than or equal to the set temperature T2 of the insulated water tank. If yes, proceed to step 3. If no, determine if the water level h2 of the insulated water tank is greater than or equal to the lowest liquid level H2min of the insulated water tank. If no, proceed to step 4. If yes, determine if the water level h2 of the insulated water tank is greater than or equal to the highest water level H2max of the insulated water tank. If yes, proceed to step 5. If no, proceed to step 1.

[0194] Step 3: Determine whether the temperature t1 of the heating water tank is greater than the temperature t2 of the insulation water tank. If yes, proceed to step 4; otherwise, proceed to step 6.

[0195] Step 4, run the above Figure 10 The heating control method of the water pump system shown is as follows: (i.e., solar panel heating is given priority; if the solar panels are insufficient, a solar panel is connected in series with a heat pump unit for heating; if that is still insufficient, the opening of F6 is adjusted to adjust the flow rate of the two parallel circuits, and the parallel electric auxiliary heating is used to raise the water temperature of a portion and mix it with the water as a supplement).

[0196] Step 5: Turn off F7, F5, F6, F1F2, B-1, and B-2. The heat pump unit and the electric auxiliary heating will be turned off. Then proceed to step 1.

[0197] Step 6: When the temperature of the heating water tank is lower than that of the insulated water tank, the solar panel will be used to keep the water in the insulated water tank warm. Turn on F7, turn on F5, turn on F6 (the water flows through path ab, not path c), turn off F1, turn on F2, turn off B-1, turn on B-2, the heat pump unit will be turned off, and proceed to step 7.

[0198] Step 7: Determine whether the heat pump unit's outlet water temperature t3 is greater than or equal to the set temperature T2 of the insulated water tank (at this time, t3 is the solar water outlet temperature after heating for a period of time, which is adjustable, 10 minutes or 15 minutes). If not, proceed to step 8; if yes, proceed to step 9.

[0199] Step 8: Turn on F7, turn on F5, turn on F6 (take path ab, not path c), turn off F1, turn on F2, turn off B-1, turn on B-2, the heat pump unit starts heating, and the electric auxiliary heating is turned off; after entering the solar panel preheating, it enters the heat pump unit to raise the temperature for insulation, and then proceeds to step 10.

[0200] Step 9: Determine whether the water level h2 in the insulated water tank is greater than or equal to the lowest liquid level H2min in the insulated water tank. If not, proceed to step 4. If yes, determine whether the water level h2 in the insulated water tank is greater than or equal to the highest water level H2max in the insulated water tank. If yes, proceed to step 5. If not, proceed to step 6.

[0201] Step 10: Determine whether the unit's outlet water temperature t3 is greater than or equal to the set temperature T2 of the insulated water tank (at this time, t3 is the outlet water temperature of the solar series unit after heating for a period of time, which is adjustable, 10 minutes or 15 minutes). If yes, proceed to step 9; otherwise, proceed to step 11. Step 11: Turn on F7, F5, and F6 (run through ab and c paths, adjust the opening of F6, for example, turn on b path at 90% water volume and c path at 10% water volume, the percentage is adjustable), turn off F1, turn on F2, turn off B-1, turn on B-2, the heat pump unit turns on for heating, and the electric auxiliary heating turns on; the water enters the solar panel for preheating, and then enters the heat pump unit for heating. Adjust the flow rate of the two parallel paths, use the parallel electric auxiliary heating to increase a portion of the water volume and temperature, mix the water and keep it warm, then proceed to step 12.

[0202] Step 12: Determine if the temperature t4 at the mixing point is greater than or equal to the set temperature T2 of the insulated water tank. If yes, proceed to step 9. If no, increase the opening of F6 in channel c and decrease the opening of channel b. Increase the flow rate in channel c and decrease the flow rate in channel b (the opening is adjustable, for example, adjust it to 80% water volume in channel b and 20% water volume in channel C, the percentage is adjustable). Proceed to step 11.
