Description

Technical Field

[0001] This application relates to the field of heat pump technology, and more specifically, to a thermal management system, a control method for the thermal management system, a control device, and a medium in the field of heat pump technology. Background Technology

[0002] The existing swimming pool and the adjacent spa pool are both temperature-regulated by independent devices; for example, the swimming pool water is heated or cooled by a heat pump, while the spa pool water is heated by built-in heaters, boilers, or other devices. This control logic requires additional heating equipment for the spa pool, resulting in high operating costs.

[0003] Therefore, how to use heat pumps to control and regulate the water temperature of swimming pools and spas, thereby saving costs, is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a thermal management system, a control method for the thermal management system, a control device, and a medium. The control method can control the water temperature of swimming pools and spas through a heat pump, thereby saving costs.

[0005] In a first aspect, a thermal management system is provided, comprising: a heat pump, a first valve assembly, and a second valve assembly; the outlet of the heat pump is selectively connected to the inlet of a first water storage device or the inlet of a second water storage device via the first valve assembly; the inlet of the heat pump is selectively connected to the outlet of the first water storage device or the outlet of the second water storage device via the second valve assembly; the first valve assembly and the second valve assembly are three-way valves, and the heat pump is used to regulate the water temperature of the first water storage device or the second water storage device.

[0006] In conjunction with the first aspect, in some possible implementations, the thermal management system further includes: a third valve assembly and a fourth valve assembly, wherein the third valve assembly and the fourth valve assembly are three-way valves; the first end of the third valve assembly is connected to the first end of the first valve assembly, and the second end of the third valve assembly is connected to the inlet of the first water storage device; the first end of the fourth valve assembly is connected to the first end of the second valve assembly, and the second end of the fourth valve assembly is connected to the outlet of the first water storage device; the third end of the third valve assembly is connected to the third end of the fourth valve assembly.

[0007] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the thermal management system further includes: a balancing water tank; the balancing water tank is connected to the second end of the first valve assembly, the second end of the second valve assembly, the inlet of the second water storage device, and the outlet of the second water storage device.

[0008] In conjunction with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the thermal management system further includes: a first water pump, a second water pump, and a third water pump; the inlet of the first water pump is connected to a first water storage device, and the outlet of the first water pump is connected to a first end of a second valve assembly; the inlet of the second water pump is connected to a balance tank, and the outlet of the second water pump is connected to a second end of the second valve assembly; the inlet of the third water pump is connected to the balance tank, and the outlet of the third water pump is connected to a second water storage device.

[0009] Compared to the existing technologies that use built-in heating devices to heat the spa pool and heat pumps to regulate the temperature of the swimming pool, the present application embodiment can use the same heat pump to regulate the water temperature of the first water storage device (i.e., the swimming pool) and the second water storage device (i.e., the spa pool), forming a multi-functional and multi-purpose heat pump system. This system can meet the different water temperature control needs of different water storage devices and avoid the risk of leakage or short circuit caused by built-in heating devices. At the same time, the heat pump consumes less electricity, which can save the operating cost of the system. Furthermore, no additional heating device is required, which saves the equipment cost of the system.

[0010] Secondly, a control method for a thermal management system is provided, the control method being applied to the thermal management system described in the first aspect or any possible implementation thereof, the control method comprising: Obtain the current operating mode of the thermal management system; Based on the current working mode, the first valve assembly and the second valve assembly are controlled to connect the heat pump to the target water storage device, which is either the first water storage device or the second water storage device. The heat pump is controlled based on the water temperature of the target water storage device to regulate the water temperature of the target water storage device.

[0011] In the above technical solution, by first obtaining the current working mode of the thermal management system, then controlling the valve components in the thermal management system according to the current working mode to connect the heat pump with the target water storage device, and finally adjusting the heat pump according to the water temperature of the target water storage device, precise and targeted control of the water temperature of different water storage devices is achieved, improving the adaptability and water temperature regulation efficiency of the thermal management system and meeting the adjustment needs of different modes.

[0012] In conjunction with the second aspect, in some possible implementations, based on the current operating mode, the first valve assembly and the second valve assembly are controlled to connect the heat pump to the target water storage device, including: If the current working mode is the first mode, the first end and the third end of the first valve assembly are connected, and the first end and the third end of the second valve assembly are connected, so that the heat pump is connected to the first water storage device. If the current working mode is the second mode, the second end of the first valve assembly and the third end of the first valve assembly are connected, and the second end of the second valve assembly and the third end of the second valve assembly are connected, so that the heat pump is connected to the second water storage device. The first mode refers to the mode for adjusting the water temperature of the first water storage device; the second mode refers to the mode for adjusting the water temperature of the second water storage device.

[0013] In the above technical solution, by distinguishing between the first mode and the second mode, the corresponding ports in the first valve assembly and the second valve assembly are controlled to be connected, so that the heat pump is accurately connected to the first water storage device or the second water storage device. This avoids ineffective connection between the heat pump and non-target water storage devices, ensures the accuracy of water temperature regulation, reduces energy waste, and meets the current water temperature regulation requirements.

[0014] Combining the second aspect and the above implementation methods, in some possible implementation methods, the current operating mode of the thermal management system is obtained, including: Obtain the target operating mode of the thermal management system; When the target working mode is the first mode, the first mode is set as the current working mode; When the target working mode is the second mode, the second mode is determined as the current working mode; When the target working mode is either the first mode or the second mode, the target working mode with the highest priority will be determined as the current working mode.

[0015] The above technical solution solves the problem of work conflict when multiple modes are activated simultaneously by obtaining the target working mode activated by the user and determining the current working mode according to priority. This ensures that the thermal management system prioritizes the execution of high-priority water temperature regulation tasks, thereby improving the orderliness and reliability of system operation.

[0016] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, when the target operating mode is the first mode and the second mode, the control method further includes: Obtain the water temperature of the target water storage device corresponding to the current working mode; The current operating mode is adjusted based on the water temperature of the target water storage device.

[0017] In the above technical solution, when the first mode and the second mode are activated simultaneously, the current working mode of the water temperature adjustment thermal management system of the target water storage device is combined with the current working mode to achieve dynamic adaptation between water temperature regulation and working mode, avoiding water temperature imbalance caused by continuous operation of a single mode and optimizing the water temperature control effect of the system.

[0018] Combining the second aspect and the above implementation methods, in some possible implementation methods, the current operating mode is adjusted based on the water temperature of the target water storage device, including: When the water temperature of the target water storage device does not meet the temperature conditions corresponding to the target water storage device, maintain the current working mode; When the water temperature of the target water storage device meets the temperature conditions corresponding to the target water storage device, the current working mode will be switched to a working mode other than the current working mode in the target working mode.

[0019] In the above technical solution, by determining whether the water temperature of the target water storage device meets the corresponding temperature conditions, the system decides to maintain or switch the current working mode, thereby realizing intelligent switching of the working mode. This ensures that the water temperature of the target water storage device meets the standard, and can also efficiently switch to other modes to complete the remaining adjustment tasks, thus improving the overall adjustment efficiency of the system.

[0020] In combination with the second aspect and the above implementation methods, in some possible implementation methods, when the target water storage device is a first water storage device, the temperature condition of the first water storage device is that the water temperature of the first water storage device is less than or equal to a first preset threshold and greater than or equal to a second preset threshold, wherein the first preset threshold is greater than the second preset threshold. When the target water storage device is the second water storage device, the temperature condition of the second water storage device is that the water temperature of the second water storage device is greater than the third preset threshold.

[0021] In the above technical solution, clear temperature conditions are set for the first water storage device and the second water storage device, providing a clear basis for judgment when switching the current working mode, avoiding blind switching of working mode, ensuring the accuracy and rationality of water temperature regulation, and adapting to the water temperature requirements of different water storage devices.

[0022] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, when the target water storage device is a first water storage device, the heat pump is controlled based on the water temperature of the target water storage device, including: When the water temperature of the first water storage device is greater than the first preset threshold, the heat pump is controlled to operate in cooling mode. When the water temperature of the first water storage device is less than or equal to the first preset threshold and greater than or equal to the second preset threshold, the heat pump is controlled to operate in standby mode. When the water temperature of the first water storage device is lower than the second preset threshold, the heat pump is controlled to operate in heating mode.

[0023] In the above technical solution, the heat pump is controlled to operate in cooling mode, standby mode, or heating mode for different water temperature ranges of the first water storage device. This achieves precise and multi-level adjustment of the water temperature of the first water storage device. It can quickly reduce the water temperature from overheating to a reasonable range, reduce energy consumption when the water temperature is suitable, and raise the temperature in time when the water temperature is too low, thus ensuring the stability and comfort of the water temperature of the first water storage device and meeting the user's needs for water temperature regulation of the first water storage device.

[0024] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, when the target water storage device is a second water storage device, the heat pump is controlled based on the water temperature of the target water storage device, including: When the water temperature of the second water storage device is greater than or equal to the fourth preset threshold, the heat pump is controlled to operate in standby mode. When the water temperature of the second water storage device is less than the fourth preset threshold and greater than or equal to the third preset threshold, the output power of the heat pump is controlled to decrease until the minimum allowable output power of the heat pump is reached. When the water temperature of the second water storage device is lower than the third preset threshold, the heat pump is controlled to operate in heating mode. Among them, the fourth preset threshold is greater than the third preset threshold.

[0025] In the above technical solution, the heat pump is controlled to operate in standby mode, power reduction mode or heating mode for different water temperature ranges of the second water storage device. It can achieve a gentle temperature rise by reducing power when the water temperature is close to the target value to avoid water temperature overshoot, and can directly heat the water to quickly rise when the water temperature is too low. At the same time, it can save energy by standing by when the water temperature reaches the target value, thus realizing precise, energy-saving and efficient regulation of the water temperature of the second water storage device.

[0026] Thirdly, a control device for a thermal management system is provided, the control device being used to control the thermal management system in the first aspect or any possible implementation thereof, the control device comprising: The acquisition module is used to acquire the current operating mode of the thermal management system; The processing module is used to control the first valve assembly and the second valve assembly based on the current working mode, so as to connect the heat pump to the target water storage device, which is either the first water storage device or the second water storage device; and to control the heat pump based on the water temperature of the target water storage device to adjust the water temperature of the target water storage device.

[0027] Fourthly, a thermal management system is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the thermal management system to perform the methods in the second aspect or any possible implementation thereof.

[0028] Fifthly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the methods described in the second aspect or any possible implementation thereof.

[0029] In a sixth aspect, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the methods described in the second aspect or any possible implementation thereof. Attached Figure Description

[0032] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] A spa pool next to a swimming pool is a specially designed spa facility. The water temperature in a spa pool is usually maintained at 38-40℃, and its main function is to provide users with a relaxing, fatigue-relieving, and health-promoting experience. A heat pump is a device that maintains a constant swimming pool water temperature, which is usually maintained at 25-35℃.

[0035] In existing technologies, the hot water source for SPA pools is usually achieved through professional water heating systems, such as built-in electric heaters, independent water heaters, and boilers; while the constant temperature function of swimming pools is controlled by heat pumps. Figure 1 This is a schematic diagram of an existing swimming pool system provided in an embodiment of this application. For example... Figure 1 As shown, the pool system includes a first water storage device 2 (swimming pool) and a second water storage device 3 (SPA pool). The constant temperature control function of the first water storage device 2 is realized by a heat pump 1, and the heating control function of the second water storage device 3 is realized by a spa pool heating device 4.

[0036] It is evident that in the existing technology, the water temperature of swimming pools and SPA pools is regulated by heat pumps and heating devices respectively. During operation, the heating device built into the SPA pool may be at risk of leakage and short circuit, and the operating cost of the entire system is relatively high.

[0037] Given the high operating costs and safety risks of existing swimming pool and spa pool systems, this application provides a thermal management system. Based on this thermal management system, a single heat pump can regulate the temperature of the swimming pool and spa pool. Compared to existing solutions that use built-in heating devices to heat the spa pool separately, this avoids the risks of electrical leakage and short circuits, and saves on the overall system configuration and operating costs.

[0038] The following will combine Figure 2The thermal management system provided in the embodiments of this application will be described in detail.

[0039] Figure 2 This is a schematic diagram of a thermal management system provided in an embodiment of this application.

[0040] like Figure 2 As shown, the thermal management system includes a heat pump 1, a first valve assembly 5, and a second valve assembly 6. The outlet of the heat pump 1 is selectively connected to the inlet of the first water storage device 2 or the inlet of the second water storage device 3 through the first valve assembly 5. The inlet of the heat pump 1 is selectively connected to the outlet of the first water storage device 2 or the outlet of the second water storage device 3 through the second valve assembly 6. The first valve assembly 5 and the second valve assembly 6 are three-way valves. The heat pump 1 is used to regulate the water temperature of the first water storage device 2 or the second water storage device 3. The target water temperature of the second water storage device 3 is higher than the target water temperature of the first water storage device 2.

[0041] For example, the water temperature required for a spa pool is usually higher than that required for a swimming pool. In this embodiment, the first water storage device 2 is also the swimming pool, and the second water storage device 3 is also the spa pool.

[0042] It should be noted that the connection mentioned in the embodiments of this application refers to the connection between two devices through a water pipe to form a waterway connection.

[0043] Based on this system setup, compared to existing technologies that use built-in heating devices to heat the spa pool and heat pumps to regulate the temperature of the swimming pool, this application embodiment can use the same heat pump to regulate the water temperature of the first water storage device (i.e., the swimming pool) and the second water storage device (i.e., the spa pool), forming a multi-functional and multi-purpose heat pump system. This system can meet the different water temperature control needs of different water storage devices and avoid the risk of leakage or short circuit caused by built-in heating devices. At the same time, the heat pump consumes less electricity, which can save on the system's operating costs. Furthermore, no additional heating device is required, saving on the system's equipment costs.

[0044] In one implementation, the thermal management system further includes a third valve assembly 7 and a fourth valve assembly 8, both of which are three-way valves; the first end of the third valve assembly 7 is connected to the first end of the first valve assembly 5, and the second end of the third valve assembly 7 is connected to the inlet of the first water storage device 2; the first end of the fourth valve assembly 8 is connected to the first end of the second valve assembly 6, and the second end of the fourth valve assembly 8 is connected to the outlet of the first water storage device 2; the third end of the third valve assembly 7 is connected to the third end of the fourth valve assembly 8.

[0045] For example, when the second end of the third valve assembly 7 is connected to the third end of the third valve assembly 7, and the second end of the fourth valve assembly 8 is connected to the third end of the fourth valve assembly 8, the water in the first water storage device 2 can be self-circulated through the connected water path. A filter device, a disinfection device, or other device can also be installed on the connected water path to clean the water in the first water storage device 2, so as to ensure the cleanliness of the water in the first water storage device 2.

[0046] Based on this system setup, water circulation in the second water storage device can be achieved, ensuring stable water quality, extending the water exchange cycle, improving swimming comfort and hygiene safety, and extending the lifespan of the pool and equipment.

[0047] In one implementation, the thermal management system further includes a balancing water tank 9; the balancing water tank 9 is connected to the second end of the first valve assembly 5, the second end of the second valve assembly 6, the inlet of the second water storage device 3, and the outlet of the second water storage device 3.

[0048] For example, the balance water tank 9 is connected to the second end of the first valve assembly 5, the second end of the second valve assembly 6, the inlet of the second water storage device 3, and the outlet of the second water storage device 3 through pipelines, forming a closed-loop fluid circuit including the valve assembly, the second water storage device, and the balance water tank. When the system is running, the water outlet of the second water storage device 3 flows into the balance water tank 9 through the pipeline. The water in the balance water tank 9 then participates in the system heat exchange or circulation regulation through the second end interfaces of the first valve assembly 5 and the second valve assembly 6, and flows back to the second water storage device 3 through the inlet of the second water storage device 3.

[0049] For example, the balance tank 9 can be pre-stored with water. The heat pump 1 heats the water in the balance tank 9 in advance. When the second water storage device 3 has a heating requirement, the hot water in the balance tank 9 can be directly input into the second water storage device 3 to improve the efficiency of water heating. At the same time, the low-temperature water in the second water storage device 3 is output to the balance tank 9 for subsequent use.

[0050] Based on this system setup, the volume buffering effect of the balancing water tank can achieve system flow distribution, pressure fluctuation suppression, and uniform water temperature mixing. At the same time, in conjunction with the on / off and adjustment actions of the valve group, it can complete the replenishment and return of circulating water in the second water storage device and the dynamic balance control of system fluids.

[0051] In one implementation, the thermal management system further includes: a first water pump 10, a second water pump 11, and a third water pump 12; the inlet of the first water pump 10 is connected to the first water storage device 2, and the outlet of the first water pump 10 is connected to the first end of the second valve assembly 6; the inlet of the second water pump 11 is connected to the balance water tank 9, and the outlet of the second water pump 11 is connected to the second end of the second valve assembly 6; the inlet of the third water pump 12 is connected to the balance water tank 9, and the outlet of the third water pump 12 is connected to the second water storage device 3.

[0052] Among them, the first water pump can also be called a swimming pool water circulation pump, etc.; the second water pump can also be called a balance tank circulation pump, etc.; the third water pump can also be called a SPA pool water circulation pump, etc.

[0053] For example, when the first water pump 10 is turned on, the water in the first water storage device 2 can be transported to the heat pump 1, or the water in the first water storage device can be circulated through the pipeline between the third valve assembly and the fourth valve assembly.

[0054] For example, when the second water pump 11 is turned on, it can transport water in the balance tank 9 toward the heat pump 1 to meet the water heating requirements of the second water storage device.

[0055] For example, when the third water pump 12 is turned on, it can deliver water from the balance tank 9 to the second water storage device 3 to raise the temperature and / or circulate the water in the second water storage device 3.

[0056] Based on this system setup, independent flow regulation and pressure stabilization of each fluid branch can be achieved, accurately allocating the flow demand of the first water storage device for water supply, the balance tank for buffer replenishment, and the second water storage device for circulating return water. This avoids flow interference and pressure fluctuations between different branches, improves system heat exchange and circulation efficiency, and ensures accurate temperature control and stable water quality circulation of the water storage device.

[0057] In one implementation, the thermal management system further includes a first temperature sensor 13, a second temperature sensor 14, a third temperature sensor 15, and a fourth temperature sensor 16.

[0058] The first temperature sensor, also known as a swimming pool water temperature sensor, is used to collect the water temperature in the first water storage device (swimming pool); the second temperature sensor, also known as a SPA pool water temperature sensor, is used to collect the water temperature in the second water storage device (SPA pool); the third temperature sensor, also known as a heat pump inlet water temperature sensor, is used to collect the water temperature on the side of the heat pump inlet; and the fourth temperature sensor, also known as a heat pump outlet water temperature sensor, is used to collect the water temperature on the side of the heat pump outlet.

[0059] Based on this system setup, water temperature monitoring can be achieved at multiple locations within the thermal management system; subsequently, the corresponding components (such as heat pumps) can be controlled based on the water temperature collected by the sensors to meet the temperature regulation requirements of the first and second water storage devices.

[0060] Optionally, the second water storage device, i.e. the SPA pool, can also be connected to a shower head for users to perform personal hygiene cleaning before and after swimming or SPA.

[0061] Based on the aforementioned thermal management system, this application embodiment also provides a control method for the thermal management system. This method controls a first valve assembly and a second valve assembly according to the current operating mode of the thermal management system, thereby connecting the heat pump to a first water storage device (i.e., a swimming pool) or a second water storage device (i.e., a spa pool). Furthermore, based on the water temperature of the first or second water storage device, the heat pump is controlled to regulate the water temperature of the storage device. This method, by controlling the heat pump, can achieve temperature regulation of the swimming pool and spa pool, thereby saving operating costs.

[0062] The following is combined with Figures 3 to 6 The control method of the thermal management system provided in the embodiments of this application will be described in detail.

[0063] Figure 3 This is a schematic flowchart illustrating a control method for a thermal management system provided in an embodiment of this application. It should be understood that this control method can be applied to a thermal management system; or, to a processor within a thermal management system; or, to a chip within a processor integrated into a thermal management system.

[0064] For example, such as Figure 3 As shown, the control method 100 includes: S101, Obtain the current operating mode of the thermal management system.

[0065] For example, the thermal management system is connected to a first water storage device and a second water storage device to regulate the water temperature of either the first or second water storage device. During the operation of the thermal management system, the current operating mode of the thermal management system is obtained.

[0066] In one implementation, the process of obtaining the current operating mode of the thermal management system may specifically include: Obtain the target operating mode of the thermal management system; When the target working mode is the first mode, the first mode is set as the current working mode; When the target working mode is the second mode, the second mode is determined as the current working mode; When the target working mode is either the first mode or the second mode, the target working mode with the highest priority will be determined as the current working mode.

[0067] For example, the target operating mode that the thermal management system needs to activate can be determined through user settings. The target operating mode can be a first mode and / or a second mode. The first mode refers to the mode for regulating the water temperature of the first water storage device (swimming pool), also known as the swimming pool water constant temperature mode, or swimming pool water constant temperature function, etc. The second mode refers to the mode for regulating the water temperature of the second water storage device (spa pool), also known as the spa pool water heating mode, or spa pool water heating function, etc. Furthermore, based on the currently activated target operating mode, the current operating mode of the thermal management system is determined.

[0068] For example, a user can enable a single mode of the thermal management system. For instance, if the user enables the first working mode, the first working mode can be directly determined as the current working mode that the thermal management system needs to run. If the user enables the second working mode, the second working mode can be directly determined as the current working mode that the thermal management system needs to run.

[0069] For example, a user can simultaneously activate two modes of the thermal management system. For instance, when the target operating modes activated by the user include the first mode and the second mode, considering that different water storage devices have different water temperature regulation requirements, only a single water storage device can be regulated at the same time. Therefore, the operating mode with the highest priority among the target operating modes can be determined as the current operating mode.

[0070] Optionally, the priority order between the first mode and the second mode can be a preset order. For example, by default, the second mode has a higher priority than the first mode, meaning that the water temperature adjustment of the second water storage device (SPA pool) is prioritized. Alternatively, the user can set the priority order between the first mode and the second mode. For example, when the user sets the priority of the first mode to be higher than the priority of the second mode, it indicates that the water temperature adjustment of the first water storage device (swimming pool) is prioritized.

[0071] For example, when the target operating mode includes a first mode and a second mode, if the priority of the first mode is higher than the priority of the second mode, then the first mode is first determined as the current operating mode of the thermal management system; if the priority of the second mode is higher than the priority of the first mode, then the second mode is first determined as the current operating mode of the thermal management system.

[0072] In this embodiment, by obtaining the target working mode activated by the user and determining the current working mode according to priority, the problem of working conflict when multiple modes are activated at the same time is solved, ensuring that the thermal management system prioritizes the execution of high-priority water temperature adjustment tasks, thereby improving the orderliness and reliability of system operation.

[0073] In one implementation, when the target operating mode is the first mode and the second mode, the control method further includes: Obtain the water temperature of the target water storage device corresponding to the current working mode; The current operating mode is adjusted based on the water temperature of the target water storage device.

[0074] For example, when the target operating mode includes both the first mode and the second mode, it indicates that the user has a need for coordinated control of two water storage devices. First, the current operating mode is determined based on the priority between the first mode and the second mode; then, the water temperature of the target water storage device corresponding to the current operating mode is monitored; and the current operating mode is adjusted accordingly based on the water temperature of the target water storage device.

[0075] For example, if the first mode has a higher priority than the second mode, the current working mode is first determined to be the first mode, and the water temperature of the first water storage device (swimming pool) is adjusted accordingly through the heat pump device; during the adjustment process, the water temperature of the first water storage device is obtained, and it is determined whether the current working mode needs to be adjusted based on the water temperature of the first water storage device.

[0076] For example, if the second mode has a higher priority than the first mode, the current working mode is first determined to be the second mode, and the water temperature of the second water storage device (SPA pool) is adjusted accordingly through the heat pump device; during the adjustment process, the water temperature of the second water storage device is obtained, and it is determined whether the current working mode needs to be adjusted based on the water temperature of the second water storage device.

[0077] In this embodiment, when the first mode and the second mode are activated simultaneously, the current working mode of the water temperature adjustment thermal management system of the target water storage device corresponding to the current working mode is combined to realize the dynamic adaptation of water temperature adjustment and working mode, avoid water temperature imbalance caused by continuous operation of a single mode, and optimize the water temperature control effect of the system.

[0078] In one implementation, the process of adjusting the current operating mode based on the water temperature of the target water storage device may specifically include: When the water temperature of the target water storage device does not meet the temperature conditions corresponding to the target water storage device, maintain the current working mode; When the water temperature of the target water storage device meets the temperature conditions corresponding to the target water storage device, the current working mode will be switched to a working mode other than the current working mode in the target working mode.

[0079] For example, during the process of adjusting the current working mode according to the water temperature of the target water storage device, if it is detected that the water temperature of the target water storage device does not meet the corresponding temperature conditions, it indicates that the current target water storage device still has a water temperature regulation requirement. In this case, the current working mode is maintained, and the water temperature of the corresponding target water storage device is regulated according to the current working mode. If it is detected that the water temperature of the target water storage device meets the corresponding temperature conditions, it indicates that the current target water storage device no longer has a water temperature regulation requirement. In this case, the current working mode needs to be adjusted, that is, the current working mode is switched to another working mode in the target working mode other than the current working mode, so as to achieve water temperature regulation of another water storage device.

[0080] For example, when the target operating modes are mode one and mode two, and mode one has a higher priority than mode two, the current operating mode is first determined to be mode one, and the corresponding target water storage device is mode one. At this time, the water temperature of mode one is prioritized for adjustment, and the water temperature of mode one is continuously monitored during this process. If the water temperature of mode one does not meet the corresponding temperature conditions, mode one remains the current operating mode. If the water temperature of mode one meets the corresponding temperature conditions, the current operating mode is switched from mode one to mode two to adjust the water temperature of mode two.

[0081] For example, if the target operating modes are mode one and mode two, and mode two has a higher priority than mode one, the current operating mode is first determined to be mode two, and the corresponding target water storage device is mode two. At this time, the water temperature of mode two is preferentially regulated, and the water temperature of mode two is continuously monitored during this process. If the water temperature of mode two does not meet the corresponding temperature conditions, mode two remains the current operating mode. If the water temperature of mode two meets the corresponding temperature conditions, the current operating mode is switched from mode two to mode one to regulate the water temperature of mode two.

[0082] In one implementation, when the target water storage device is a first water storage device, the temperature condition of the first water storage device is that the water temperature of the first water storage device is less than or equal to a first preset threshold and greater than or equal to a second preset threshold, wherein the first preset threshold is greater than the second preset threshold. When the target water storage device is the second water storage device, the temperature condition of the second water storage device is that the water temperature of the second water storage device is greater than the third preset threshold.

[0083] For example, if the current operating mode is mode one, and the corresponding target water storage device is the first water storage device, i.e., the swimming pool, and the water temperature regulation requirement of the swimming pool is constant temperature control, then the temperature condition corresponding to the first water storage device can be that the water temperature of the first water storage device is less than or equal to a first preset threshold, and the water temperature of the first water storage device is greater than or equal to a second preset threshold. When the water temperature of the first water storage device meets the corresponding temperature condition, i.e., the water temperature of the first water storage device is within the above-mentioned preset range, it indicates that the water temperature of the swimming pool is already in a constant temperature state, and there is no need to continue adjusting the water temperature of the first water storage device. Therefore, mode one can be switched to mode two to adjust the water temperature of the second water storage device. When the water temperature of the first water storage device does not meet the above-mentioned temperature condition, mode one is maintained to adjust the water temperature of the first water storage device to a constant temperature state.

[0084] In one implementation, the first preset threshold and the second preset threshold are two pre-set parameters, wherein the first preset threshold is greater than the second preset threshold. For example, the first preset threshold is 25°C and the second preset threshold is 35°C.

[0085] In another implementation, a first preset threshold and a second preset threshold are determined based on the user-set swimming pool temperature. For example, the user-set swimming pool temperature is... Then the first preset threshold can be determined as The second preset threshold is determined as follows: ,in, It can be set to 3℃ or 5℃, etc.

[0086] For example, if the current operating mode is the second mode, and the corresponding target water storage device is the second water storage device, i.e., the SPA pool, and the water temperature regulation requirement of the SPA pool is heating control, then the temperature condition corresponding to the second water storage device can be that the water temperature of the second water storage device is greater than a third preset threshold. When the water temperature of the second water storage device is greater than the third preset threshold, it indicates that the water temperature of the SPA pool has reached the preset temperature, and there is no need to continue adjusting the water temperature of the second water storage device. The second mode can then be switched to the first mode to adjust the water temperature of the first water storage device. When the water temperature of the second water storage device is less than or equal to the third preset threshold, the second mode is maintained to adjust the water temperature of the second water storage device to rise to the third preset temperature.

[0087] In one implementation, the third preset threshold is the SPA pool temperature preset by the user, for example, the third preset threshold can be set to 38℃, etc.

[0088] In another implementation, a third preset threshold is determined based on the user-set SPA pool temperature. For example, the user sets the pool temperature to be... Then the third preset threshold can be determined as ,in, It can be set to 3℃ or 5℃, etc.

[0089] In this embodiment, specific temperature conditions are set for the first and second water storage devices, providing a clear basis for switching the current working mode, avoiding blind switching of working modes, ensuring the accuracy and rationality of water temperature regulation, and adapting to the water temperature requirements of different water storage devices.

[0090] In this embodiment, by determining whether the water temperature of the target water storage device meets the corresponding temperature conditions, the system decides to maintain or switch the current working mode, thereby achieving intelligent switching of the working mode. This ensures that the water temperature of the target water storage device meets the standard, while also efficiently switching to other modes to complete the remaining adjustment tasks, thus improving the overall adjustment efficiency of the system.

[0091] S102, based on the current working mode, control the first valve assembly and the second valve assembly to connect the heat pump to the target water storage device, which is either the first water storage device or the second water storage device.

[0092] If the current working mode is the first mode, then the target water storage device is determined to be the first water storage device; if the current working mode is the second mode, then the target water storage device is determined to be the second water storage device.

[0093] For example, after determining the current operating mode of the thermal management system, the first valve assembly and the second valve assembly in the thermal management system are controlled according to the current operating mode to connect the heat pump to the target water storage device corresponding to the current operating mode.

[0094] In one implementation, the process of controlling the first valve assembly and the second valve assembly based on the current operating mode to connect the heat pump to the target water storage device may specifically include: If the current working mode is the first mode, the first end and the third end of the first valve assembly are connected, and the first end and the third end of the second valve assembly are connected, so that the heat pump is connected to the first water storage device. If the current working mode is the second mode, the second end of the first valve assembly and the third end of the first valve assembly are connected, and the second end of the second valve assembly and the third end of the second valve assembly are connected, so that the heat pump is connected to the second water storage device. The first mode refers to the mode for adjusting the water temperature of the first water storage device; the second mode refers to the mode for adjusting the water temperature of the second water storage device.

[0095] For example, when the current operating mode is determined to be the first mode, if the heat pump in the thermal management system needs to be connected to the first water storage device, it is necessary to control the first end of the first valve assembly to be connected to the third end of the first valve assembly so that the outlet of the heat pump is connected to the inlet of the first water storage device. At this time, the second end of the first valve assembly is in the closed state. At the same time, the first end of the second valve assembly and the third end of the second valve assembly are connected to be connected so that the outlet of the first water storage device is connected to the inlet of the heat pump. At this time, the second end of the second valve assembly is in the closed state. Thus, the connection between the heat pump and the first water storage device can be realized.

[0096] It should be noted that this implementation is based on a thermal management system that includes a first valve assembly and a second valve assembly, but does not include a third valve assembly and a fourth valve assembly.

[0097] In one implementation, when the thermal management system includes a first valve assembly, a second valve assembly, a third valve assembly, and a fourth valve assembly, the third valve assembly and the fourth valve assembly can be further controlled in conjunction with the current operating mode or the operating mode of the heat pump.

[0098] For example, if the current operating mode is the first mode, in addition to controlling the second end and the third end of the first valve assembly to be connected, and controlling the second end and the third end of the second valve assembly to be connected, the third valve assembly and the fourth valve assembly can also be controlled in combination with the operating mode of the heat pump.

[0099] For example, when the heat pump operates in heating or cooling mode, the first and second ends of the third valve assembly are connected, while the third end is closed; similarly, the first and second ends of the fourth valve assembly are connected, while the third end is closed. This allows water flowing through the first valve assembly to enter the first water storage device via the third valve assembly, and water in the first water storage device to flow into the heat pump sequentially via the fourth and second valve assemblies, thus forming a circulating water path for the first water storage device to regulate its water temperature. When the heat pump operates in standby mode, the second and third ends of the third valve assembly are connected, while the first end is closed; similarly, the second and third ends of the fourth valve assembly are connected, while the first end is closed, forming a self-circulating water path for the first water storage device to meet its disinfection and cleaning requirements.

[0100] For example, if the current working mode is the second mode, based on controlling the second end and the third end of the first valve assembly to be connected, and controlling the second end and the third end of the second valve assembly to be connected so that the heat pump is connected to the second water storage device, the second end and the third end of the third valve assembly are connected, and the first end of the third valve assembly is cut off, and the second end and the third end of the fourth valve assembly are connected, and the first end of the fourth valve assembly is cut off, so as to form a self-circulating water circuit of the first water storage device and meet the disinfection and cleaning requirements of the first water storage device.

[0101] In one implementation, for a thermal management system equipped with a first water pump, a second water pump, and a third water pump, the water pumps are controlled according to the current operating mode or the operating mode of the heat pump.

[0102] For example, if the current working mode is the first mode, the first water pump is turned on to transport the water in the first water storage device to the heat pump; at the same time, if the second water storage device does not have a water temperature regulation requirement, the second and third water pumps are turned off.

[0103] For example, if the current operating mode is the second mode, the water pump is further controlled in conjunction with the operating mode of the heat pump system.

[0104] For example, when the heat pump is in heating mode, the first water pump is turned on to ensure the self-circulation of the first water storage device; at the same time, the second and third water pumps are turned on. Water in the balance tank enters the heat pump through the second water pump for heating and is then re-injected into the balance tank. Water in the balance tank enters the second water storage device through the third water pump. Water in the second water storage device then returns to the balance tank. This cycle continues to increase the water temperature of the second water storage device.

[0105] For example, when the heat pump is in standby mode, the first water pump is turned on to ensure the self-circulation of the first water storage device; at the same time, the third water pump is turned on to satisfy the self-circulation of the second water storage device.

[0106] For example, Figure 4 This is a schematic diagram of system connectivity under the first mode provided in the embodiments of this application. For example... Figure 4 As shown, Figure 4Solid lines represent actually connected water paths, dashed lines represent unconnected water paths, and arrows indicate the direction of water flow. When the current operating mode of the thermal management system is the first mode, heat pump 1 is used to regulate the water temperature of the first water storage device 2. At this time, the water in the first water storage device 2 is sequentially transported to the inlet of heat pump 1 through the second end of the fourth valve assembly 8, the first end of the fourth valve assembly 8, the first end of the second valve assembly 6, and the third end of the second valve assembly 6 via the first water pump 10. Heat pump 1 heats or cools the input water and outputs it through the outlet of heat pump 1. The water then flows into the first water storage device 2 sequentially through the third end of the first valve assembly 5, the first end of the first valve assembly 5, the first end of the third valve assembly 7, and the second end of the third valve assembly 7, thereby regulating the water temperature of the first water storage device 2. At the same time, the water in the second water storage device 3 and the balance tank 9 can achieve self-circulation through the third water pump 12.

[0107] For example, Figure 5 This is a schematic diagram of system connectivity under the second mode provided in the embodiments of this application. For example... Figure 5 As shown, Figure 5 Solid lines represent actually connected water paths, dashed lines represent unconnected water paths, and arrows indicate the direction of water flow. When the current operating mode of the thermal management system is the second mode, heat pump 1 is used to regulate the water temperature of the second water storage device 3. At this time, the second water pump 11 delivers water from the balance tank 9 through the second end and the third end of the second valve assembly to the inlet of heat pump 1. After the heat pump 1 heats the input water, it is output through the outlet of heat pump 1, passing through the third end and the second end of the first valve assembly and flowing into the balance tank 9. Then, the third water pump 12 inputs water from the balance tank 9 into the second water storage device 3, while some water from the second water storage device 3 flows into the balance tank 9. Simultaneously, the first water pump 10 re-enters the first water storage device 2 through the second end, the third end, the third end, and the second end of the fourth valve assembly, thus achieving water circulation. In addition, a filtration device and a disinfection device may also be installed in the circulating water circuit of the first water storage device. The embodiments of this application do not describe the above devices in detail.

[0108] In this embodiment, by distinguishing between the first mode and the second mode, the corresponding ports in the first valve assembly and the second valve assembly are controlled to be connected, so that the heat pump is accurately connected to the first water storage device or the second water storage device. This avoids ineffective connection between the heat pump and non-target water storage devices, ensures the accuracy of water temperature regulation, reduces energy waste, and meets the current water temperature regulation requirements.

[0109] S103, based on the water temperature of the target water storage device, controls the heat pump to adjust the water temperature of the target water storage device.

[0110] For example, after the heat pump is connected to the target water storage device, the water temperature of the target water storage device is obtained through a temperature sensor installed in the target water storage device; then, the heat pump is controlled according to the water temperature of the target water storage device, so as to adjust the water temperature of the target water storage device through the heat pump.

[0111] For example, see the above. Figure 2 The thermal management system shown in the figure obtains the water temperature of the first water storage device 2 through the first temperature sensor 13 when the target water storage device is the first water storage device 2; and obtains the water temperature of the second water storage device 3 through the second temperature sensor 14 when the target water storage device is the second water storage device 3.

[0112] In one implementation, when the target water storage device is a first water storage device, the process of controlling the heat pump based on the water temperature of the target water storage device may specifically include: When the water temperature of the first water storage device is greater than the first preset threshold, the heat pump is controlled to operate in cooling mode. When the water temperature of the first water storage device is less than or equal to the first preset threshold and greater than or equal to the second preset threshold, the heat pump is controlled to operate in standby mode. When the water temperature of the first water storage device is lower than the second preset threshold, the heat pump is controlled to operate in heating mode.

[0113] The first preset threshold is greater than the second preset threshold; the first preset threshold and the second preset threshold are used to indicate the highest and lowest temperatures that the water temperature of the first water storage device needs to be maintained.

[0114] Optionally, the first preset threshold and the second preset threshold are two pre-set parameters, wherein the first preset threshold is greater than the second preset threshold. For example, the first preset threshold is 25℃ and the second preset threshold is 35℃. Alternatively, the first and second preset thresholds are determined based on the user-set swimming pool temperature. For example, the user-set swimming pool temperature is... Then the first preset threshold can be determined as The second preset threshold is determined as follows: ,in, It can be set to 3℃ or 5℃, etc.

[0115] For example, when the target water storage device is determined to be the first water storage device, the operating mode of the heat pump is determined according to the different ranges of water temperature in the first water storage device.

[0116] For example, when the water temperature of the first water storage device is greater than the first preset threshold, it indicates that the current water temperature of the first water storage device is higher than the user's expected temperature and the water temperature needs to be lowered. At this time, the heat pump is controlled to operate in cooling mode.

[0117] For example, when the water temperature of the first water storage device is less than or equal to the first preset threshold and the water temperature of the first water storage device is greater than or equal to the second preset threshold, it indicates that the current water temperature is within a suitable range and there is no need to adjust the water temperature. Therefore, the heat pump can be controlled to operate in standby mode to avoid unnecessary energy consumption of the heat pump.

[0118] For example, when the water temperature of the first water storage device is lower than the second preset threshold, it indicates that the current water temperature is too low and needs to be increased. Therefore, the heat pump is controlled to operate in heating mode.

[0119] Optionally, to avoid frequent switching of the heat pump's operating mode due to water temperature fluctuations, the heat pump's operating mode can be switched when the water temperature meets the preset conditions for a preset duration threshold (e.g., 3s or 5s).

[0120] In this embodiment, the heat pump is controlled to operate in cooling mode, standby mode, or heating mode for different water temperature ranges of the first water storage device. This achieves precise and multi-level adjustment of the water temperature of the first water storage device, which can quickly reduce the water temperature from overheating to a reasonable range, reduce energy consumption when the water temperature is suitable, and raise the temperature in time when the water temperature is too low. This ensures the stability and comfort of the water temperature of the first water storage device and meets the user's needs for water temperature regulation of the first water storage device.

[0121] In one implementation, when the target water storage device is a second water storage device, the process of controlling the heat pump based on the water temperature of the target water storage device may specifically include: When the water temperature of the second water storage device is greater than or equal to the fourth preset threshold, the heat pump is controlled to operate in standby mode. When the water temperature of the second water storage device is less than the fourth preset threshold and greater than or equal to the third preset threshold, the output power of the heat pump is controlled to decrease until the minimum allowable output power of the heat pump is reached. When the water temperature of the second water storage device is lower than the third preset threshold, the heat pump is controlled to operate in heating mode. The fourth preset threshold is greater than the third preset threshold. The third preset threshold can be the minimum temperature that the second water storage device needs to reach, as set by the user. The fourth preset threshold is used to indicate a safe temperature to avoid scalding the user. The fourth preset threshold is a fixed value and cannot be adjusted by the user, thus protecting the user's safety.

[0122] For example, when the target water storage device is determined to be a second water storage device, the operating mode of the heat pump is controlled in combination with the range of water temperature of the second water storage device.

[0123] For example, when the water temperature of the second water storage device is greater than or equal to the fourth preset threshold, the excessively high water temperature may cause scalding to the user and pose a safety hazard. In this case, the heat pump can be controlled to operate in standby mode and the water in the second water storage device will not be heated.

[0124] For example, when the water temperature of the second water storage device is less than the fourth preset threshold, or when the water temperature of the second water storage device is greater than or equal to the third preset threshold, the current water temperature has reached the temperature set by the user. Then, the output power of the heat pump can be controlled to gradually decrease, indicating a reduction to the minimum allowable output power of the heat pump, thus avoiding unnecessary high-efficiency output of the heat pump.

[0125] For example, when the water temperature of the second water storage device is lower than the third preset threshold, the current water temperature is lower than the temperature set by the user. Therefore, the heat pump needs to be controlled to operate in heating mode so that the water temperature of the second water storage device reaches above the third preset threshold in order to meet the user's heating needs.

[0126] In this embodiment, the heat pump is controlled to operate in standby mode, power reduction mode, or heating mode for different water temperature ranges of the second water storage device. This allows for gentle heating by reducing power when the water temperature is close to the target value, avoiding overheating, and direct heating for rapid heating when the water temperature is too low. At the same time, it saves energy by operating in standby mode when the water temperature reaches the target value, thus achieving precise, energy-saving, and efficient regulation of the water temperature of the second water storage device.

[0127] In summary, in this embodiment, by first obtaining the current working mode of the thermal management system, then controlling the valve components in the thermal management system according to the current working mode to connect the heat pump with the target water storage device, and finally adjusting the heat pump according to the water temperature of the target water storage device, precise and targeted control of the water temperature of different water storage devices is achieved, improving the adaptability and water temperature regulation efficiency of the thermal management system and meeting the adjustment needs of different modes.

[0128] Figure 6 This is a schematic flowchart illustrating another control method for a thermal management system provided in an embodiment of this application. It should be understood that this control method can be applied to a thermal management system; or, to a processor within a thermal management system; or, to a chip within a processor integrated into a thermal management system.

[0129] For example, taking a swimming pool as the first water storage device and a spa pool as the second water storage device, such as... Figure 6 As shown, the control method 200 includes: S201, Obtain the current operating mode of the thermal management system.

[0130] For example, during the operation of a thermal management system, its current operating mode is acquired.

[0131] In one implementation, the current operating mode is determined based on the target operating mode of the thermal management system currently enabled by the user.

[0132] Optionally, the implementation method of the current working mode can be determined based on the target working mode. Figure 2 The relevant description of S101 is omitted here from the embodiments of this application.

[0133] S202, if the current working mode is the first mode, control the first end of the first valve assembly and the third end of the first valve assembly to conduct, and control the first end of the second valve assembly and the third end of the second valve assembly to conduct, so as to connect the heat pump to the swimming pool.

[0134] For example, after obtaining the current working mode of the thermal management system, if it is determined that the current working mode is the first mode, that is, the mode of regulating the water temperature of the swimming pool through the heat pump, the first end and the third end of the first valve component in the thermal management system are controlled to be open, and at the same time, the first end and the third end of the second valve component are controlled to be open, so that the swimming pool can be connected to the heat pump through the water pipe, and the water in the swimming pool can circulate through the circulation water path.

[0135] S203, obtain the water temperature of the swimming pool.

[0136] For example, after the heat pump is connected to the swimming pool, the water temperature of the swimming pool is obtained through a first temperature sensor installed in the swimming pool.

[0137] S204: When the water temperature in the swimming pool exceeds the first preset threshold, control the heat pump to operate in cooling mode.

[0138] For example, the first preset threshold can be determined based on the user-set swimming pool temperature. When the user-set swimming pool temperature is... When this happens, the first preset threshold can be determined as follows: .

[0139] For example, when the water temperature in the swimming pool is detected to be greater than a first preset threshold, that is... When the water temperature is below or equal to the first preset threshold, the heat pump is controlled to operate in cooling mode to lower the pool water temperature.

[0140] For example, when the heat pump is in cooling mode, the first end and the second end of the third valve assembly are connected, and the third end of the third valve assembly is cut off. The first end and the second end of the fourth valve assembly are connected, and the third end of the fourth valve assembly is cut off. This allows the water flowing through the first valve assembly to flow into the first water storage device through the third valve assembly, and the water in the first water storage device to flow into the heat pump in sequence through the fourth valve assembly and the second valve assembly, thereby forming a circulating water path for the first water storage device. This allows the heat pump to cool the water, thereby reducing the water temperature of the swimming pool.

[0141] S205: When the water temperature of the swimming pool is less than or equal to the first preset threshold and greater than or equal to the second preset threshold, control the heat pump to run in standby mode.

[0142] For example, the second preset threshold can be determined based on the user-set swimming pool temperature. When the user-set swimming pool temperature is... When this happens, the second preset threshold can be determined as follows: .

[0143] For example, when the water temperature in the swimming pool is less than or equal to a first preset threshold and greater than or equal to a second preset threshold, that is... When the heat pump is in standby mode, there is no need to adjust the water temperature through the heat pump.

[0144] For example, in the standby mode of heat pump operation, the second end of the third valve assembly and the third end of the third valve assembly can be controlled to be open and the first end of the third valve assembly can be closed, and the second end of the fourth valve assembly and the third end of the fourth valve assembly can be controlled to be open and the first end of the fourth valve assembly can be closed, so as to form a self-circulating water circuit of the first water storage device and meet the disinfection and cleaning requirements of the first water storage device.

[0145] S206, When the water temperature of the swimming pool is lower than the second preset threshold, control the heat pump to operate in heating mode.

[0146] For example, when the water temperature in the swimming pool is detected to be lower than a second preset threshold, that is... At that time, the heat pump is controlled to operate in heating mode to raise the water temperature of the swimming pool until the water temperature of the swimming pool is greater than or equal to the second preset threshold.

[0147] For example, when the heat pump is in cooling mode, the first end and the second end of the third valve assembly are connected, and the third end of the third valve assembly is cut off. The first end and the second end of the fourth valve assembly are connected, and the third end of the fourth valve assembly is cut off. This allows the water flowing through the first valve assembly to flow into the first water storage device through the third valve assembly, and the water in the first water storage device to flow into the heat pump in sequence through the fourth valve assembly and the second valve assembly, thereby forming a circulating water path for the first water storage device. This allows the heat pump to cool the water, thereby reducing the water temperature of the swimming pool.

[0148] S207, if the current working mode is the second mode, control the second end of the first valve assembly and the third end of the first valve assembly to conduct, and control the second end of the second valve assembly and the third end of the second valve assembly to conduct, so that the heat pump is connected to the SPA pool.

[0149] For example, after obtaining the current working mode of the thermal management system, if it is determined that the current working mode is the second mode, that is, the mode of regulating the water temperature of the SPA pool through the heat pump, the second end and the third end of the first valve assembly are connected; at the same time, the second end and the third end of the second valve assembly are connected, so that the SPA pool can be connected to the heat pump through the water pipe, and the water in the SPA pool can circulate through the circulating water path.

[0150] S208, obtain the water temperature of the SPA pool.

[0151] For example, after the heat pump is connected to the SPA pool, the water temperature of the SPA pool is obtained through a second temperature sensor installed in the SPA pool.

[0152] S209, when the water temperature of the SPA pool is greater than or equal to the fourth preset threshold, control the heat pump to run in standby mode.

[0153] For example, the fourth preset threshold, used to ensure user safety, refers to the highest temperature allowed to be reached in the SPA pool. The fourth preset threshold can be used... express.

[0154] For example, when the water temperature in the SPA pool is greater than or equal to a fourth preset threshold, that is... At this time, the heat pump is controlled to standby mode, and the water in the SPA pool is not heated to avoid the water temperature being too high and endangering the user's safety.

[0155] S210, when the water temperature of the SPA pool is less than the fourth preset threshold and greater than or equal to the third preset threshold, the output power of the heat pump is controlled to decrease until the minimum allowable output power of the heat pump is reached.

[0156] For example, the third preset threshold can be the swimming pool temperature set by the user. .

[0157] For example, when the water temperature in the SPA pool is less than the fourth preset threshold and greater than or equal to the third preset threshold, that is... At the same time, the output power of the heat pump is controlled to decrease gradually until the minimum allowable output power of the heat pump is reached, so as to achieve a continuous heat preservation effect on the SPA pool and avoid the water temperature of the SPA pool from dropping rapidly below the third preset threshold due to directly shutting off the heat pump.

[0158] S211, when the water temperature of the SPA pool is less than the third preset threshold, control the heat pump to operate in heating mode.

[0159] For example, when the water temperature in the SPA pool is lower than a third preset threshold, that is... At that time, the heat pump is controlled to operate in heating mode so that the temperature of the SPA pool rises above the third preset threshold to meet the user's needs.

[0160] In one implementation, the temperature regulation method of the SPA pool may also include a cooling mode; when the SPA pool has a cooling mode, the implementation method of controlling the heat pump in conjunction with the temperature of the SPA pool can be found in the relevant description of the water temperature regulation of the swimming pool corresponding to the first mode; the embodiments of this application will not be repeated here.

[0161] In summary, in this embodiment of the application, by controlling the connection between the heat pump and the swimming pool or SPA pool according to the current working mode of the thermal management system, and flexibly switching the cooling, heating, and standby modes of the heat pump and adjusting the output power according to the relationship between the water temperature of the corresponding pool and the preset threshold, precise and efficient control of the water temperature of the swimming pool and SPA pool is achieved. At the same time, the operating status of the heat pump can be dynamically adjusted according to the water temperature demand, improving energy utilization efficiency and ensuring the stability of water temperature and user experience of different pools.
