[0037] In one embodiment, the water inlet of the water inlet valve is connected to the pipeline of the external water inlet interface, and the water outlet of the water inlet valve is connected to the water inlet of the water storage tank, so as to control whether the external water source enters the test system;

[0038] The water storage tank comprises a tank body, an upper water level float, a lower water level float, a water tank water inlet and a water tank water outlet, wherein the water tank water inlet is connected to the water outlet of the water inlet valve, and the water tank water outlet is connected to the water inlet of the water pump; the upper water level float and the lower water level float are both placed in the water storage tank, the setting position of the upper water level float is determined according to the amount of water required to be heated by the heat storage and heat exchange device to be tested, and the setting position of the lower water level float is determined according to a protective water level at the bottom of the water storage tank; when the water level in the water storage tank touches the upper water level float or the lower water level float, the upper water level float and the lower water level float respectively feed back an upper water level signal and a lower water level signal to the control system; the water storage tank body is used to store water from an external water source and plays a role in water pressure balance, so as to avoid the influence of the difference in flow rate of the external water source on the thermal performance of the heat storage and heat exchange device to be tested, and then control the flow rate entering the heat storage and heat exchange device through the water pump to ensure the consistency of the experimental test conditions;

[0039] The water inlet of the water pump is connected to the water outlet of the water storage tank, and the water outlet of the water pump is connected to the water inlet of the flow device, and the water pump is used to transport the water in the water storage tank to the heat storage and heat exchange device;

[0040] The water inlet of the flow device is connected to the water outlet of the water pump, and the water outlet of the flow device is connected to the water inlet of the water outlet valve, and the flow device is used to monitor the amount of water entering the heat storage and heat exchange device;

[0041] The water inlet of the water outlet valve is connected to the water outlet of the flow device, and the water outlet of the water outlet valve is connected to the water inlet of the heat storage and heat exchange device. The water outlet valve is used to prevent the high-temperature water of the heat storage and heat exchange device from flowing back into the water pump and the water storage tank;

[0042] The water inlet of the heat storage and heat exchange device is connected to the water outlet of the water outlet valve, and the heat storage and heat exchange device is used to perform heat exchange on the incoming water source; the water outlet of the heat storage and heat exchange device is connected to the external waterway, and the warm water after heat exchange is output to the outside;

[0043] The control device (central controller) is connected to the water inlet valve, the water pump, the flow device, the water outlet valve and the heater of the heat storage and heat exchange device, and is used to control the opening and closing states of each electrical component according to the logic signal and record the number of cycles of the entire test system; the control device is also connected to temperature probes located in the water storage tank, the inside of the heat storage and heat exchange device and the water outlet of the test system, respectively, and the temperature probes are used to monitor the water temperature of the water storage tank, the internal temperature of the heat storage and heat exchange device and the water temperature of the water outlet of the heat storage and heat exchange device;

[0044] The heat storage and heat exchange device also includes a buzzer and a lamp bead, and the buzzer and the lamp bead are electrically connected to the control device; when an abnormality occurs during the test, such as failure of the water inlet valve to open or close, failure of the temperature control device of the heat storage and heat exchange device, etc., the control device outputs a signal to start the buzzer to sound an alarm, and at the same time controls the lamp bead to flash to prompt the tester, and different abnormal conditions correspond to different alarm sounds and lamp bead flashing colors.

[0045] The testing method comprises the steps of:

[0046] S1 obtains the working mode of the heat storage and heat exchange device. If the heat storage and heat exchange device is in the test mode, the water inlet valve is opened to allow external water to enter the water storage tank, and the water replenishment status information of the water storage tank is obtained;

[0047] In this embodiment, the working mode of the heat storage and heat exchange device is obtained. If it is in the waiting test mode, a command is sent to open the water inlet valve. Under the action of its own pressure, the external water source flows into the water storage tank through the external water inlet interface and the water inlet valve, thereby providing sufficient water for subsequent tests; in the water storage tank, the upper water level float monitors the water level change in real time; when the water level gradually rises and touches the upper water level float, the position of the upper water level float changes, generating a corresponding signal change, and transmitting it to the control system, so that the system receives and analyzes this signal, thereby obtaining the water replenishment status information of the water storage tank, ensuring that the water storage tank is replenished with an appropriate amount of water, and avoiding insufficient or excessive water replenishment.

[0048] S2: When the water replenishment status information indicates that the water replenishment is completed, the water inlet valve is closed, and the heat storage and heat exchange device starts equipment preheating according to the preset working conditions, and the equipment preheating status information of the heat storage and heat exchange device is obtained during the equipment preheating process;

[0049] In this embodiment, when it is determined that the water replenishment status information is completed, a closing command can be sent to the water inlet valve to stop the inflow of external water source, prevent the water storage tank from overflowing due to excessive water replenishment, and ensure the safety of the test environment; at the same time, the system sends a start command to the heater of the heat storage and heat exchange device according to the preset working conditions, and the heater starts to work to preheat the inside of the heat storage and heat exchange device so that the device reaches the appropriate test temperature conditions. A temperature probe is provided inside the heat storage and heat exchange device, and the temperature probe monitors the internal temperature of the device in real time. As the heater works, the temperature gradually rises, and the temperature probe converts the temperature change into an electrical signal and transmits it to the control system for analysis and processing of these signals, thereby obtaining the preheating status information of the device and determining whether it meets the preset preheating standard.

[0050] S3: When the preheating status information of the equipment indicates that the preheating is completed, the water pump and the water outlet valve are turned on to allow the water source in the water storage tank to enter the heat storage and heat exchange device to perform a heat exchange test, and obtain the test status information of the heat storage and heat exchange device;

[0051] In this embodiment, when the system confirms that the preheating status information of the equipment is that the preheating is completed, it sends an opening instruction to the water pump and the water outlet valve respectively, the water pump starts, pumps out the normal temperature water in the water storage tank, transports it to the flow device through the pipeline, and then enters the internal water path of the heat storage heat exchange device through the water outlet valve. The normal temperature water flows in the internal water path of the heat storage heat exchange device and exchanges heat with the heat in the heat storage heat exchange device. The water temperature gradually increases, thereby completing the heat exchange; through the preliminary preparation, the same initial adjustment is provided for the heat storage heat exchange device, and then the heat storage and heat release process of the heat storage heat exchange device in actual use is simulated to test its performance. By real-time monitoring of the progress of the heat exchange test, it is determined whether the heat storage heat exchange device has completed a complete test cycle.

[0052] S4: When the test status information indicates that the test is completed, the water pump and the water outlet valve are turned off to reset the working mode of the heat storage heat exchange device to the waiting mode, and the flow device is used to measure the amount of water entering the heat storage heat exchange device to obtain the single hot water output amount;

[0053] In this embodiment, when the system determines that the test status information is that the test is completed, it sends a closing command to the water pump and the water outlet valve to stop supplying water to the heat storage heat exchange device; at the same time, the system resets the working mode of the heat storage heat exchange device to the test mode, so that the device returns to its initial state and prepares for the next test; finally, the system reads the data recorded by the flow device to obtain the amount of water entering the heat storage heat exchange device this time, that is, the single hot water output; the single hot water output is used to evaluate the performance of the heat storage heat exchange device in each test cycle.

[0054] S5: Repeat steps S1-S4 in a loop until the single hot water output is less than the preset reference hot water output, then the loop ends;

[0055] In this embodiment, multiple cycle tests are performed to comprehensively evaluate the performance changes of the heat storage and heat exchange device under different cycle times; a preset reference hot water output is used as a judgment standard. If the single hot water output is less than the preset reference hot water output, it proves that the heat storage and heat exchange device has aged to the extent that it needs to be repaired. At this time, the test can be stopped and the cycle can be ended;

[0056] Specifically, after completing the first test, the single hot water output is marked as L0, which is the basic performance of the heat storage and heat exchange device; S1-S4 is repeated continuously, and each time a cycle is completed, the control system records the number of cycles (T1, T2, T3...Tn), and the corresponding amount of water passing through the flow device (L1, L2, L3...Ln); based on L0, the preset benchmark hot water output LN can be obtained, LN=0.8L0, LN represents the hot water output when the performance of the heat storage and heat exchange device decays to 80% of the benchmark performance; when LN=Ln, the performance of the surface heat storage and heat exchange device has decayed to 80% after multiple tests, and the test can be stopped at this time to end the cycle;

[0057] By testing the single hot water output corresponding to the heat storage and heat exchange cycle of each heat storage and heat exchange device, it is possible to accurately determine the state of the heat storage and heat exchange device when its performance decays to 80% of the benchmark performance, and the life test results are more accurate.

[0058] S6 calculates the aging test data according to all the single hot water outputs generated during the circulation process and generates a test completion signal;

[0059] In this embodiment, all the single hot water output recorded is added up to calculate the relevant data reflecting the aging degree of the heat storage and heat exchange device (total hot water output). Specifically, the total hot water output Lt of the heat storage and heat exchange device is calculated first, Lt = L1 + L2 + L3 + ... + Ln, the total hot water output can directly reflect the life performance capacity of the heat storage and heat exchange device; in addition, a performance attenuation curve can be drawn based on all the single hot water outputs and its performance attenuation rate can be calculated, and the performance attenuation rate or performance attenuation curve can assist in judging the aging process of the heat storage and heat exchange device under different working hours; the combination of the two can comprehensively judge the life performance of the heat storage and heat exchange device;

[0060] The total hot water volume obtained by adding up the single hot water output of each heat storage and heat release cycle can measure the life performance capability of the heat storage and heat exchange device to be tested; the total hot water volume indicator can avoid misjudgment of the life performance of the heat storage and heat exchange device due to different cycle times / number of cycles between different heat storage and heat exchange devices.

[0061] In the embodiment of the present invention, the working mode of the heat storage and heat exchange device is first obtained. When it is in the waiting-for-test mode, the water inlet valve is opened to replenish water to the water storage tank, and the water replenishment process is controlled to be completed smoothly according to the water replenishment status information. After the water replenishment is completed, the heat storage and heat exchange device starts equipment preheating according to the preset working conditions to complete the preliminary preparations for the aging test and provide the same initial environment for each aging test; after the preheating is completed, the water pump and the water outlet valve are opened to allow the water source in the water storage tank to enter the heat storage and heat exchange device for heat exchange testing. When the test is completed, the water pump and the water outlet valve are closed to reset the working mode of the device to the waiting-for-test mode. The test process is closed-loop managed by measuring the single hot water output after each cycle. The test steps are then repeated in a cycle. The single hot water output is recorded and compared with the preset benchmark hot water output after each cycle is completed. The cycle is terminated when the single hot water output is less than the preset value. Finally, the aging test data is calculated based on all the recorded single hot water outputs and a test completion signal is generated. The heat storage and heat exchange device is subjected to multiple heat release cycle tests, and the aging test data is calculated based on the results of all heat storage and heat release cycle tests, so as to determine the aging degree of the heat storage and heat exchange device after multiple tests, and then test the life performance of the heat storage and heat exchange device.

[0062] See also Figure 2 , two embodiments of the testing method in the embodiment of the present invention include:

[0063] An upper water level float is provided in the water storage tank, and the upper water level float is used to monitor the upper water level height and output an upper water level signal;

[0064] In this embodiment, the setting position of the upper water level float is determined according to the amount of water required to be heated by the heat storage and heat exchange device to be tested. When the water level in the water tank touches the upper water level float, the upper water level float feeds back an upper water level signal to the control system, indicating that the water level in the water tank is sufficient and the water replenishment process can be stopped.

[0065] The step of obtaining the water replenishment status information of the water storage tank includes:

[0066] 101. Monitor the time when the external water source enters the water storage tank to obtain the water inlet time;

[0067] In this embodiment, a first timing module is provided in the control system, and the first timing module is used to record the time when the external water source flows into the water tank, that is, the water inflow time; the water inflow time is used to assist in determining the water replenishment progress of the water tank.

[0068] 102. When the water inflow time is greater than a preset water inflow time threshold and the upper water level float outputs an upper water level signal, water replenishment status information is generated and the water replenishment status information is marked as water replenishment completed;

[0069] In this embodiment, the control system continuously compares the acquired water inlet time with the preset water inlet time threshold, and monitors the signal output by the upper water level float in real time; when the water inlet time is greater than the threshold and the signal output by the upper water level float is received, the surface water replenishment is successfully completed, and the system automatically generates water replenishment status information, and clearly marks it as "water replenishment completed" in the internal data record; after the water replenishment status information is generated, the system will close the water inlet valve according to the preset procedure to prevent the water tank from overflowing.

[0070] 103. When the water inflow time is greater than a preset water inflow time threshold and the upper water level float does not output an upper water level signal, water replenishment status information is generated and the water replenishment status information is marked as water replenishment failure;

[0071] In this embodiment, the control system continuously compares the water inlet time with the preset water inlet time threshold, and monitors the signal output by the upper water level float in real time. If the water inlet time exceeds the threshold but the upper water level float signal is not received, it means that there is an abnormality in the water replenishment process. The system generates water replenishment status information and marks it as "water replenishment failure"; after the water replenishment status information is generated, the system will terminate the test process and generate a corresponding alarm signal according to the preset procedure.

[0072] See also Figure 3 , three embodiments of the testing method in the embodiment of the present invention include:

[0073] 201. When the water replenishment status information indicates that the water replenishment fails, a first test termination signal is generated;

[0074] In this embodiment, when the water replenishment status is identified as "water replenishment failure", the system immediately generates the first test termination signal, stops the operation of related equipment in the test system, such as closing the water inlet valve, stopping the water pump, and closing the heater of the heat storage device to be tested, and triggers the alarm device, starts the buzzer to issue an intermittent alarm, and clearly informs the tester that this abnormality occurred during the system water replenishment stage. By designing time protection measures and water volume protection measures, it is possible to avoid the test system from maintaining abnormal operation when it is abnormal; at the same time, it can remind and warn the tester of the type of abnormality that occurred in the test system.

[0075] See also Figure 4 , four embodiments of the testing method in the embodiment of the present invention include:

[0076] 301. Perform time-efficiency monitoring on the preheating time of the heat storage and heat exchange device to obtain the preheating time;

[0077] In this embodiment, a second timing module is provided in the control system, and the second timing module is used to record the equipment preheating time of the heat storage and heat exchange device, that is, the preheating time; the preheating time is used to assist in judging the preheating progress of the heat storage and heat exchange device.

[0078] 302. Monitor the internal temperature of the heat storage and heat exchange device to obtain first temperature data;

[0079] In this embodiment, during the preheating process of the heat storage and heat exchange device, the temperature probe installed inside the heat storage and heat exchange device continuously collects real-time temperature data inside the device, namely, first temperature data, and integrates these temperature data into a system; the first temperature data provides real-time information on the temperature inside the device. If the first temperature data is abnormal, such as heating up too slowly or too quickly, or the temperature is too high or too low, possible faults in the heating system or the device itself can be discovered in time to ensure that the equipment is tested under normal temperature conditions.

[0080] 303. When the preheating time is greater than a preset preheating time threshold and the first temperature data is less than a preset first temperature threshold data, device preheating state information is generated and the device preheating state information is marked as preheating completed;

[0081] In this embodiment, the system continuously compares the acquired preheating time with the preset preheating time threshold, and compares the first temperature data with the preset first temperature threshold data. When the preheating time exceeds the threshold and the first temperature data is less than the threshold, it indicates that the heat storage and heat exchange device has completed preheating and has reached the conditions for the next test. The system generates equipment preheating status information and marks it as "preheating completed" in the internal data record.

[0082] 304. When the first temperature data is greater than or equal to the preset first temperature threshold data, device preheating status information is generated, and the device preheating status information is marked as preheating failure;

[0083] In this embodiment, in the process of continuously comparing the preheating time and temperature data, regardless of whether the preheating time is greater than the preset preheating time threshold, when the first temperature data is greater than the threshold, it indicates that an abnormality has occurred in the device preheating process; at this time, the system generates device preheating status information and marks it as "preheating failure". After the preheating status information is generated, the system will terminate the test process and generate a corresponding alarm signal according to the preset procedure.

By designing time protection measures and temperature protection measures, it is possible to avoid abnormal operation of the test system when it is abnormal, and at the same time remind and warn the tester of the type of abnormality that occurred in the test system.

[0089] In this embodiment, the lower water level float is arranged in the water tank, and the position of the lower water level float is determined according to a protective water level at the bottom of the water tank; when the water level in the water tank touches the lower water level float, the lower water level float feeds back a lower water level signal to the control system, indicating that the water source in the water tank has been discharged, and it is necessary to turn off the water pump and stop the test.

[0093] 502. Monitor the water flow temperature at the outlet of the heat storage and heat exchange device to obtain second temperature data;

[0094] In this embodiment, during the heat exchange process of the heat storage and heat exchange device, the temperature probe installed at the water outlet of the heat storage and heat exchange device continuously collects real-time temperature data of the water flow at the water outlet of the device, that is, the second temperature data, and integrates these temperature data into a system; the second temperature data provides real-time information of the water flow that has completed heat exchange through the heat storage and heat exchange device; by monitoring the temperature of the water flow at the water outlet, the heat exchange effect of the heat storage and heat exchange device can be intuitively understood; if the second temperature data is abnormal, such as the temperature rises too slowly or too quickly, the temperature is too high or too low, the possible faults of the heating system or the device itself can be discovered in time to ensure that the equipment is tested under normal temperature conditions.

[0095] 503. When the heat exchange time is greater than the preset heat exchange threshold time, or the lower water level float outputs a lower water level signal, if the second temperature data is less than the preset second temperature threshold data, then generate test status information, and mark the test status information as test completed;

[0096] In this embodiment, the system continuously monitors the heat exchange time, the lower water level float signal and the second temperature data; when the heat exchange time exceeds the preset threshold or the lower water level float outputs a lower water level signal, the system will check the second temperature data. If the temperature data is less than the preset second temperature threshold data, it indicates that the heat exchange test process is over, and the system will generate test status information and mark it as "test completed".

[0097] 504. When the heat exchange time is greater than the preset heat exchange threshold time, or the lower water level float outputs a lower water level signal, if the second temperature data is greater than or equal to the second temperature threshold data, then generate test status information, and mark the test status information as test failure;

[0098] In this embodiment, under the same monitoring conditions, when the heat exchange time exceeds the preset threshold or the lower water level float outputs a signal, and the second temperature data is greater than the preset second temperature threshold data, it indicates that there is an abnormality in the heat exchange test process, and the system generates test status information and marks it as "test failed"; when the preheating status information is generated, the system will terminate the test process and generate a corresponding alarm signal according to the preset procedure.

By designing time protection measures and water volume protection measures, it is possible to avoid abnormal operation of the test system when it is abnormal, and at the same time remind and warn the tester of the type of abnormality that occurred in the test system.
