[0036] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0037] Please refer to Figure 1 The embodiment of the present invention provides a method for identifying dirt and blockage in a closed circulating water system 100. The method for identifying dirt and blockage includes: S01, obtaining a first water pressure value of the closed circulating water system 100; S03, when the first water pressure value is greater than or equal to the set water pressure threshold, controlling the water pump 14 to operate with set parameters and obtaining water flow data; S05, after the water flow data is stable, record the first water flow data; S07: When the first water flow rate data is less than the set value, output a system dirty blockage prompt message.

[0038] In the above-mentioned dirty blockage identification method, when the first water pressure value of the closed-loop circulating water system 100 is greater than or equal to the set water pressure threshold, the water pump 14 is controlled to operate with the set parameters and obtain the first water flow data. When the first water flow data is less than the set value, it can be determined that the system is dirty and blocked, and the system dirty blockage prompt information is output, so that the user can discover the dirty blockage of the system in time and improve the user experience.

[0039] Specifically, in one embodiment, the closed circulating water system 100 can use water as a heat transfer medium, and when the water pump 14 is running, the flow of water can be accelerated, thereby improving the heat transfer efficiency of the closed circulating water system 100. It is understandable that in other embodiments, the closed circulating water system 100 can also use other fluids as heat transfer media, not limited to water, and when the water pump 14 is running, the flow of the heat transfer medium can be accelerated.

[0040] Please combine Figure 2In one embodiment, the closed circulating water system 100 may include a heat exchanger 16 and a thermal device 18, and the thermal device 18 includes a heat exchange device and / or a heat storage device. The heat exchange device includes but is not limited to a heat exchanger, a coil, a floor heating, etc., and the heat storage device includes but is not limited to a water tank. The heat exchanger 16, the water pump 14 and the thermal device 18 are connected in sequence through pipelines to form a circulating water circuit. When the water pump 14 is activated, the water flow speed in the pipeline can be accelerated, thereby improving the heat exchange effect. The closed circulating water system 100 can operate in a cooling mode or a heating mode.

[0041] In the related art, after the closed-loop water circulation system 100 is used for a long time, impurities in the heat exchange medium will gradually accumulate in the filter in the pipeline, causing the filter to be blocked, affecting the reliability and heat transfer effect of the closed-loop water circulation system 100. The current solution is mainly to clean the filter 38 through regular on-site maintenance, or to wait until the system is protected or fails before checking and cleaning the filter, resulting in failure to discover and deal with it in time, affecting normal use.

[0042] In the implementation mode of the present invention, please combine Figure 2 The closed circulating water system 100 is provided with a water flow detection device 20 and a water pressure detection device 22, which can obtain the water flow value and water pressure value in the pipeline of the closed circulating water system 100. Figure 3 The closed-loop water circulation system 100 may include a control component 44, which is electrically connected to the water pump 14, the water flow detection device 20 and the water pressure detection device 22. The control component 44 can obtain data output by the water flow detection device 20 and the water pressure detection device 22, and control the operation and shutdown of the water pump 14.

[0043] The control component 44 may be preset with a set water pressure threshold and a set value. The set water pressure threshold and the set value may be fixed or adjustable. The specific values ​​of the water pressure threshold and the set value may be determined and stored in the closed circulating water system 100 based on experience, testing, simulation, etc., and the present invention does not specifically limit this.

[0044] When the closed-loop water circulation system 100 starts working, the water pressure detection device 22 continuously detects the water pressure value in the pipeline, and the control component 44 can obtain the first water pressure value. When the first water pressure value detected by the water pressure detection device 22 is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate with the set parameters. The set parameters can be specifically defined according to actual conditions, and the present invention does not make specific limitations on this.

[0045] The water flow detection device 20 continuously detects the water flow in the pipeline, and the control component 44 can obtain the water flow data. After the water flow data is stable, the control component 44 records the first water flow data. Optionally, within a preset time period, the water flow data is maintained within a preset fluctuation range, which can be regarded as the water flow data being stable. The present invention does not specifically limit the preset time period and the preset fluctuation range. In one example, the fluctuation range of the water flow data within a preset time period (such as within 5 minutes) is maintained within ±5%, that is, the control component 44 can determine that the water flow data is stable.

[0046] When the first water flow data is less than the set value, the control component 44 can output system dirty blockage prompt information. In one embodiment, the control component 44 can control the closed circulating water system 100 to issue a prompt message, for example, the control component 44 controls the closed circulating water system 100 to issue a signal reminder including but not limited to sound, light, etc., or sends the prompt message to the user's terminal to notify the user to check the dirty blockage of the closed circulating water system 100. The user's terminal includes but is not limited to a mobile phone, a tablet computer, a personal computer, a wearable smart device, etc. In summary, users can promptly discover dirty blockages in the system, thereby improving user experience.

[0047] When the first water flow data is greater than or equal to the set value, the control component 44 sends a detection completion signal, and the control system exits the dirt and blockage identification detection.

[0048] In some embodiments, obtaining the first water pressure value of the closed circulating water system 100 includes: obtaining the first water pressure value of the closed circulating water system 100 when the closed circulating water system 100 is powered on again or the water pump 14 has not been running for a period of time greater than a set time threshold.

[0049] In this way, the accuracy of the dirt and blockage identification method can be improved.

[0050] Specifically, in one embodiment, re-powering on may refer to the process of re-powering the machine to restore it to an operable state after the machine stops running due to power outage, maintenance, failure, etc. When the closed-loop water system 100 is powered on again, the water pressure detection device 22 continuously detects the water pressure value in the pipeline, and the control component 44 can obtain the first water pressure value. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to run with set parameters and obtain water flow data. After the water flow data is stable, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message to allow the user to promptly discover the dirty blockage of the system.

[0051] In one embodiment, the continuous non-operation of the water pump 14 may mean that the water pump 14 may not perform any pumping operation for a period of time due to system shutdown, maintenance, etc. The control component 44 can detect the continuous non-operation time of the water pump 14. When the continuous non-operation time of the water pump 14 is greater than the set time threshold, the control component 44 obtains the first water pressure value through the water pressure detection device 22. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to operate with the set parameters and obtains water flow data. After the water flow data is stable, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message to allow the user to promptly discover the dirty blockage of the system.

[0052] The specific value of the set time threshold can be determined and stored in the closed-loop water circulation system 100 according to empirical values, tests, simulations, etc., and the present invention does not specifically limit this. The set time threshold can be fixed or adjustable. In one embodiment, the set time threshold can be adjusted according to the dirty and blocked condition of the closed-loop water circulation system 100, or the closed-loop water circulation system 100 can be adjusted according to user input. In one example, the range of the set time threshold is 24 hours to 48 hours.

[0053] In some embodiments, the set parameter includes a rated speed or a maximum speed of the water pump 14 .

[0054] In this way, the operation of the water pump 14 can be controlled by the rotation speed of the water pump 14 .

[0055] Specifically, when the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period of time greater than a set time threshold, the control component 44 can control the operation of the water pump 14 at the rated speed or maximum speed of the water pump 14, so that the heat exchange medium flows at a faster speed, thereby improving detection efficiency and accuracy.

[0056] The rated speed and maximum speed of the water pump 14 can be stored in the closed-loop water circulation system 100. When the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period of time greater than a set time threshold, the control component 44 can read the above-mentioned set parameters to control the operation of the water pump 14.

[0057] The setting parameters may be fixed or adjustable, and the present invention does not specifically limit this. Optionally, the water pump 14 may be a variable frequency water pump.

[0058] In some embodiments, the set value is the larger of the first preset value and the second preset value, the second preset value=K×Q0, K is 0.5 to 1, and Q0 is the second water flow data. The dirty blockage identification method includes: controlling the water pump 14 to operate with set parameters and obtaining a second water pressure value of the closed circulating water system 100, when the second water pressure value is greater than or equal to the set water pressure threshold, recording the second water flow data after the water flow data is stabilized, and when the second water flow data is greater than or equal to the first preset value, storing the second water flow data.

[0059] In this way, the accuracy of the dirt and blockage identification method can be improved to a certain extent.

[0060] Specifically, when the closed-loop water circulation system 100 starts to be debugged and operated, the control component 44 controls the water pump 14 to operate with set parameters, the water pressure detection device 22 continuously detects the water pressure in the pipeline, and the control component 44 can obtain the second water pressure value. The control component 44 can obtain the water flow data in the pipeline through the water flow detection device 20. When the second water pressure value is greater than or equal to the set water pressure threshold, the control component 44 can record the second water flow data after the water flow data is stable, so as to be used as a basis for the subsequent system to identify dirt and blockage.

[0061] When the second water flow data is greater than or equal to the first preset value, the control component 44 stores the second water flow data for use in the subsequent determination of the dirty blockage identification method of the system.

[0062] Optionally, the first preset value is adjustable. The specific value of the first preset value can be determined and stored in the closed circulating water system 100 according to experience, testing, simulation, etc., and the present invention does not specifically limit this. In one example, the first preset value can be the minimum flow rate at which the system can operate.

[0063] After the closed-loop water circulation system 100 passes the above-mentioned water flow data storage process, if the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period of time greater than the set time threshold, the system performs subsequent dirty blockage identification. When the first water pressure value of the closed-loop water circulation system 100 is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to run with the set parameters and obtain the first water flow data. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message.

[0064] Optionally, the set value is the larger of the first preset value and the second preset value, which ensures to a certain extent that the system can maintain sufficient water flow for normal operation under all operations. The first preset value and the second preset value can be determined and stored in the closed circulating water system 100 based on experience, testing, simulation, etc., and the present invention does not specifically limit this.

[0065] In the embodiment of the present invention, the second preset value is calculated by K×Q0, where Q0 is the second water flow data obtained by the above water flow data storage process, and the coefficient K ranges from 0.5 to 1. By adjusting the coefficient k, the system can flexibly adapt to different operating conditions and installation scenarios, thereby improving the safety and reliability of the system to a certain extent.

[0066] K is 0.5 to 1, that is, 0.5≤K≤1. In some examples, K=0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1 or other values ​​greater than or equal to 0.5 and less than or equal to 1. The K value can be determined based on factors such as operating conditions, actual installation scenarios, and actual flow requirements.

[0067] The second preset value may be in the range of 0.5×Q0 to Q0 according to different values ​​of K, that is, 0.5×Q0≤second preset value≤Q0. In some examples, the second preset value=0.5×Q0, 0.55×Q0, 0.6×Q0, 0.65×Q0, 0.7×Q0, 0.75×Q0, 0.8×Q0, 0.85×Q0, 0.9×Q0, 0.95×Q0, Q0 or other values ​​greater than or equal to 0.5×Q0 and less than or equal to Q0.

[0068] In some embodiments, the dirty blockage identification method includes: when the second water pressure value is less than a set water pressure threshold, outputting a water pressure insufficient prompt message.

[0069] In this way, insufficient water pressure in the system can be discovered in time, so that water replenishment measures can be taken in time.

[0070] Specifically, when the closed-loop water circulation system 100 starts to debug and run, the control component 44 controls the water pump 14 to run with set parameters, the water pressure detection device 22 continuously detects the water pressure in the pipeline, and the control component 44 can obtain the second water pressure value. When the second water pressure value detected by the water pressure detection device 22 is less than the set water pressure threshold, the control component 44 outputs a water pressure shortage prompt message. In one embodiment, the control component 44 can control the closed-loop water circulation system 100 to issue a prompt message, for example, the control component 44 controls the closed-loop water circulation system 100 to issue a signal reminder including but not limited to sound, light, etc., or sends a prompt message to the user's terminal to notify the user to check the water pressure of the closed-loop water circulation system 100. The user's terminal includes but is not limited to a mobile phone, a tablet computer, a personal computer, a wearable smart device, etc. Therefore, the user can promptly discover the situation of insufficient water pressure in the system. Optionally, after receiving the water pressure shortage prompt message, the user can operate the control component 44 to replenish water to the system and increase the water pressure.

[0071] After the control component 44 outputs the insufficient water pressure prompt information, the water pressure detection device 22 re-detects the water pressure in the pipeline continuously. After the system is replenished with water, the water pressure gradually increases. When the second water pressure value detected by the water pressure detection device 22 is greater than or equal to the set water pressure threshold, the control component 44 can obtain water flow data through the water flow detection device 20. After the water flow data is stable, the control component 44 records the second water flow data.

[0072] In some embodiments, the blockage identification method includes: after outputting system blockage prompt information, outputting system blockage inspection and cleaning instructions.

[0073] In this way, users can be guided to quickly check and solve dirt and blockage problems.

[0074] Specifically, after outputting the system dirty blockage prompt information, the control component 44 will output the system dirty blockage inspection and cleaning instructions. Optionally, the system dirty blockage inspection includes but is not limited to prompting steps such as confirming the dirty blockage prompt information, confirming that the system is shut down, checking the filter 38, checking the pipes, and checking the water pump 14, and the cleaning instructions include but are not limited to prompting steps such as cleaning the filter 38, cleaning the pipes, cleaning the water pump 14, and restarting the system. Therefore, after receiving the dirty blockage prompt information, the user can quickly check the system and solve the dirty blockage problem according to the dirty blockage inspection and cleaning instructions.

[0075] It is understandable that dirt and blockage may also be caused by factors outside the filter. Therefore, the dirt and blockage identification method of the embodiment of the present invention can also be applied to a circulating water system without a filter.

[0076] In one embodiment, the closed-loop water circulation system 100 includes a machine visual device, and the dirty blockage prompt information and the system dirty blockage inspection and cleaning guide information can be alternately displayed on the machine visual device. It is understandable that the control component 44 can also send the system dirty blockage inspection and cleaning guide to the user's terminal, so that the user can view the system dirty blockage inspection and cleaning guide. The user's terminal includes but is not limited to a mobile phone, a tablet computer, a personal computer, a wearable smart device, etc.

[0077] In certain embodiments, the dirty blockage identification method includes: after outputting the system dirty blockage inspection and cleaning instructions, resetting the system dirty blockage prompt according to a manual reset signal.

[0078] In this way, the correct maintenance and stable operation of the system can be ensured to a certain extent.

[0079] Specifically, in one embodiment, the cleaning instructions may include a manual reset prompt. After outputting the system dirty blockage inspection and cleaning instructions, the control component 44 may output a manual reset prompt. After the user performs a dirty blockage inspection and cleaning of the system according to the system dirty blockage inspection and cleaning instructions, the user may perform a manual reset operation on the system according to the manual reset prompt. The manual reset operation generates a manual reset signal, and the control component 44 causes the system to re-enter the normal operating mode according to the manual reset signal, and will re-enter the automatic detection of dirty blockage identification until the detection is completed and automatically exited, which can ensure the correct maintenance and stable operation of the system to a certain extent.

[0080] In some embodiments, the dirty blockage identification method includes: obtaining a forced exit detection signal, and exiting the dirty blockage detection process according to the forced exit detection signal.

[0081] This provides users with operational flexibility to a certain extent.

[0082] Specifically, in one embodiment, after the control component 44 outputs the system dirty blockage prompt, the user may be unable to clean the system immediately, etc., and can instruct the control component 44 to exit the detection through instructions. After the control component 44 obtains the forced exit detection signal, the control component 44 controls the system to exit the above dirty blockage detection process, that is, the system no longer outputs dirty blockage prompt information according to the dirty blockage identification method, and the system continues to operate. Therefore, manual forced exit detection provides users with operational flexibility to a certain extent to adapt to different needs.

[0083] It is understandable that after the user manually forces the system to exit the dirty blockage identification detection, the control component 44 will automatically resume the dirty blockage identification detection after the set recovery time, so as to protect the normal operation of the system. The present invention does not specifically limit the setting of the recovery time. In one example, the control component 44 will automatically resume the dirty blockage identification detection at a time point of 48 hours after the system is forced to exit the dirty blockage detection.

[0084] Please combine Figure 3 An embodiment of the present invention provides a closed circulating water system 100, which includes a control component 44 and a water pump 14. The control component 44 is electrically connected to the water pump 14. The control component 44 includes a processor 46, a memory 48, and a computer program stored in the memory 48 and capable of running on the processor 46. When the computer program is executed by the processor 46, the steps of the dirt and blockage identification method in any of the above-mentioned embodiments are implemented.

[0085] In the above-mentioned closed circulating water system 100, when the first water pressure value of the closed circulating water system 100 is greater than or equal to the set water pressure threshold, the water pump 14 is controlled to operate with the set parameters and obtain the first water flow data. When the first water flow data is less than the set value, it can be determined that the system is dirty and blocked, and the system dirty and blocked prompt information is output, so that the user can discover the dirty and blocked situation of the system in time, thereby improving the user experience.

[0086] The above explanation of the implementation method and beneficial effects of the closed-loop water circulation system 100 dirt and blockage identification method is also applicable to the closed-loop water circulation system 100 of this embodiment, and will not be elaborated here in detail to avoid redundancy.

[0087] In some embodiments, please combine Figure 4 The closed circulating water system 100 includes a first filter 40, a hydraulic module 24 and a hot water supply device. The hydraulic module 24 includes a buffer water tank 26, a hot water inlet connector 28 and a cold water outlet connector 30. The buffer water tank 26 includes a hot water connector 32 and a cold water connector 34. The water pump 14 is respectively connected to the hot water connector 32 and the hot water inlet connector 28. The first filter 40 is respectively connected to the cold water connector 34 and the cold water outlet connector 30. The hot water supply device is respectively connected to the hot water inlet connector 28 and the cold water outlet connector 30.

[0088] In this way, the water pump 14 can deliver the hot water output by the water heater to the buffer water tank 26 or the water heater, while the first filter 40 can reduce the amount of impurities and sediments entering the water heater, thereby preventing blockage to a certain extent.

[0089] Specifically, in one embodiment, the closed circulating water system 100 may be a heating unit. In one embodiment, the heating unit may include a hot water supply device, a hydraulic module 24, and a hot water device. The hydraulic module 24 may be connected to the hot water supply device and the hot water device through a pipeline. The hot water device includes but is not limited to a domestic water tank, a zone one system, and a zone two system.

[0090] Optionally, the hot water supply device may include an air conditioning device, which may include a heat pump system. The air conditioning device may utilize the heat pump system to heat cold water into hot water and pass the hot water into the hydraulic module 24 through the hot water inlet connector 28 for distribution.

[0091] Optionally, the water supply device may include a gas boiler, which can use the heat generated by gas combustion to heat cold water to form hot water. The hot water output by the gas boiler is input into the hydraulic module 24 through the hot water inlet connector 28 for distribution.

[0092] Optionally, the water supply device includes a solar water heater, which is connected to the hot water inlet connector 28 through a pipeline. The solar water heater is used to heat water using solar energy to form hot water, and the hot water can be transmitted to the hydraulic module 24 for distribution.

[0093] Please combine Figure 4 In one embodiment, the water pump 14 can pump a portion of the hot water inputted from the hot water supply device through the hot water inlet connector 28 to the hot water outlet connector 50. The hot water outlet connector 50 can be connected to the hot water user device, and the hot water outlet connector 50 outputs the hot water to the hot water user device. Figure 4 In the embodiment shown, there are three hot water outlet joints 50, the upper hot water outlet joint 50 is connected to the area 2 system, the middle hot water outlet joint 50 is connected to the area 1 system, and the lower hot water outlet joint 50 is connected to the domestic water tank. Another part of the hot water inputted by the hot water supply device through the hot water inlet joint 28 is pumped to the hot water joint 32, and this part of the hot water enters the buffer water tank 26 from the hot water joint 32 for storage.

[0094] In other embodiments, when the amount of hot water required by the water heater is large, all the hot water output by the water heater supply device may flow into the water heater.

[0095] The hot water in the buffer water tank 26 can be output to the hydraulic module 24 via the hot water connector 32. In the first aspect, the hydraulic module 24 delivers the hot water to the coil in the domestic water tank via the hot water outlet connector 50 below. The hot water transmits heat to the domestic water in the domestic water tank through the coil, thereby increasing the temperature of the domestic water. The domestic water tank can be connected to a water outlet valve such as a faucet or a shower head, and the domestic water with increased temperature can be supplied to users through the water outlet valve such as a faucet or a shower head.

[0096] Secondly, the hydraulic module 24 can deliver hot water to the area 1 system through the middle hot water outlet joint 50. The area 1 system may include a heater suspended on the indoor ceiling, and the heater includes but is not limited to a fan coil unit (FCU). The fan coil unit can dissipate the heat of the hot water into the room to increase the indoor temperature.

[0097] In a third aspect, the hydraulic module 24 can deliver hot water to the area 2 system through the hot water outlet connector 50 above. The area 2 system can include floor heating and / or radiators. The floor heating can dissipate the heat of the hot water to the ground, and the radiator can dissipate the heat of the hot water to the room, thereby increasing the temperature of the ground and the room.

[0098] Please combine Figure 4The cold water in the buffer water tank 26 can enter the hydraulic module 24 through the cold water joint 34, and the cold water can flow through the first filter 40, so that the first filter 40 filters the cold water. The filtered cold water can be output to the hot water supply device through the cold water outlet joint 30, and the hot water supply device heats the cold water to form hot water. The hot water output by the hot water supply device is input to the hydraulic module 24 through the hot water inlet joint 28, and enters the buffer water tank 26 through the hot water joint 32 for storage, or is output to the hot water device. Since the cold water entering the hot water supply device is the cold water filtered by the first filter 40, the impurities and sediments in the water flow can be reduced, and the risk of reduced working efficiency of the hot water supply device due to wear or blockage of impurities can be reduced.

[0099] Optionally, in the embodiment of the present invention, the first filter 40 may include a magnetic filter. The magnetic filter may use magnetic materials to absorb metal and magnetic impurities in the water flow.

[0100] In some embodiments, the hydraulic module 24 includes a water pressure detection device 22 and a water flow detection device 20 , and the water pressure detection device 22 and the water flow detection device 20 are disposed upstream of the first filter 40 .

[0101] In this way, the area where the first filter 40 is located can be detected for dirt, so that dirt blockage of the hydraulic module 24 can be discovered in time.

[0102] Specifically, the cold water in the buffer water tank 26 can enter the hydraulic module 24 through the cold water connector 34. The water pressure detection device 22 and the water flow detection device 20 are arranged upstream of the second filter 42. The cold water will pass through the water pressure detection device 22 and the water flow detection device 20 and then flow through the first filter 40. The filtered cold water can be output from the cold water outlet connector 30 to the hot water supply device for heat exchange to form hot water.

[0103] When the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period of time greater than the set time threshold, the control component 44 can obtain the first water pressure value through the water pressure detection device 22. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to run with the set parameters and obtain water flow data. After the water flow data is stable, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message, allowing the user to promptly discover the dirty blockage of the system, so that the first filter 40 can be disassembled and cleaned to solve the dirty blockage problem.

[0104] In certain embodiments, the water heating device includes at least one of an air conditioning device, a gas furnace, and a solar water heater.

[0105] In this way, the source of hot water can be configured as needed.

[0106] Specifically, in one embodiment, the water supply device includes an air conditioner, a gas furnace and a solar water heater. For example, when the closed-loop water system 100 operates in a heating mode, if the ambient temperature is low and the efficiency of the air conditioner is low, the gas furnace and / or the solar water heater can be started to produce hot water. When the light is insufficient, the efficiency of the solar water heater is low, and the gas furnace and / or the air conditioner can be started to produce hot water. When there is no gas, the air conditioner and / or the solar water heater can be started to produce hot water.

[0107] In other embodiments, the water heating device includes any one or any two of an air conditioning device, a gas furnace, and a solar water heater.

[0108] In some embodiments, the hydraulic module 24 includes a first water supply connector 36 , and the closed circulating water system 100 includes a second filter 42 , which is connected to the first water supply connector 36 and the cold water outlet connector 30 .

[0109] In this way, the second filter 42 can filter impurities in the makeup water, thereby protecting the normal operation of the closed circulation water system 100 to a certain extent.

[0110] Specifically, please combine Figure 1 , tap water (cold water) flows into the hydraulic module 24 through the first water supply joint 36, and the second filter 42 is set on the pipeline between the first water supply joint 36 and the cold water outlet joint 30. The cold water flows through the second filter 42, merges with the cold water output from the buffer water tank 26 through the cold water joint 34, and then flows out to the cold water outlet joint 30, so that the cold water flows into the hot water supply device for heat exchange to form hot water. Water contains calcium and magnesium ions. During the flow of cold water, these ions will form scale and adhere to the inner wall of the pipe, causing the pipe to be narrow or even completely blocked, affecting the normal operation of the hydraulic module 24.

[0111] Optionally, in the embodiment of the present invention, the second filter 42 may include a soft water filter. After the cold water passes through the soft water filter, the water quality can be softened, which can effectively reduce the content of calcium and magnesium ions in the water, reduce the risk of pipe clogging due to scale to a certain extent, make the water flow smoother, and protect the normal operation of the hydraulic module 24 to a certain extent.

[0112] In some embodiments, the hydraulic module 24 includes a water pressure detection device 22 and a water flow detection device 20 , and the water pressure detection device 22 and the water flow detection device 20 are disposed upstream of the second filter 42 .

[0113] In this way, the area where the second filter 42 is located can be detected for dirt, so that dirt blockage of the hydraulic module 24 can be discovered in time.

[0114] Specifically, tap water (cold water) flows into the hydraulic module 24 through the first water supply joint 36. The water pressure detection device 22 and the water flow detection device 20 are arranged upstream of the second filter 42. The cold water will pass through the water pressure detection device 22 and the water flow detection device 20 and then flow through the second filter 42. It will merge with the cold water output from the buffer water tank 26 through the cold water joint 34 and then flow out to the cold water outlet joint 30, so that the cold water flows into the hot water supply device for heat exchange to form hot water.

[0115] When the closed-loop water circulation system 100 is powered on again or the water pump 14 has not been running for a period of time greater than the set time threshold, the control component 44 can obtain the first water pressure value through the water pressure detection device 22. When the first water pressure value is greater than or equal to the set water pressure threshold, the control component 44 controls the water pump 14 to run with the set parameters and obtain water flow data. After the water flow data is stable, the first water flow data is recorded. When the first water flow data is less than the set value, the control component 44 outputs a system dirty blockage prompt message, allowing the user to promptly discover the dirty blockage of the system, so that the second filter 42 can be disassembled and cleaned to solve the dirty blockage problem.

[0116] An embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by the processor 46, the steps of the dirt blockage identification method of any of the above embodiments are implemented.

[0117] For example, the control method implemented when the computer program is executed by the processor 46 includes: S01, obtaining a first water pressure value of the closed circulating water system 100; S03, when the first water pressure value is greater than or equal to the set water pressure threshold, controlling the water pump 14 to operate with set parameters and obtaining water flow data; S05, after the water flow data is stable, record the first water flow data; S07: When the first water flow rate data is less than the set value, output a system dirty blockage prompt message.

[0118] It should be noted that the above-mentioned closed-loop water circulation system 100 dirt and blockage identification method and the explanation and beneficial effects of the implementation of the closed-loop water circulation system 100 are also applicable to the computer-readable storage medium of the implementation of the present invention. To avoid redundancy, they are not elaborated here.
