DETAILED DESCRIPTION

[0040] The present invention provides a heat storage and heat exchange performance detection method and detection system. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples.

[0041] In the description of the present invention, it should be understood that the terms "installation", "connection" and the like should be understood in a broad sense, and a person skilled in the art can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0042] See also Figure 1 The present invention provides a heat storage and heat exchange performance detection method. The heat storage and heat exchange performance detection system includes a control device and a conveying mechanism, an exhaust mechanism and a detection mechanism electrically connected to the control device respectively. The input end of the conveying mechanism is used to connect to an external water supply device 41, the output end of the conveying mechanism is used to connect to the inlet of the heat storage and heat exchange device 42 to be tested, the exhaust mechanism is used to connect to the outlet of the heat storage and heat exchange device 42 to be tested, the first output end of the exhaust mechanism is connected to the detection mechanism, and the second output end of the exhaust mechanism is used to connect to an external collection device; the heat storage and heat exchange performance detection method includes:

[0043] 100. Control and adjust the working states of the conveying mechanism and the exhaust mechanism so that the heat storage and heat exchange performance detection system switches to the heat storage mode;

[0044] 200. After the heating power of the heat storage and heat exchange device 42 to be tested is increased to a preset power value, a temperature rise timing is performed.

[0046] In this embodiment, the exhaust mode is executed before the heat release mode is executed, so that the high-temperature steam that may appear or exist in the pipeline can be discharged outside the detection system first, avoiding direct contact between the high-temperature steam and the tester, thereby ensuring the safety of the tester during the test process.

[0049] 600. Calculate the heat storage and heat exchange ratio based on the heating time, test results and heat release time.

[0050] The present application discloses a heat storage and heat exchange performance testing method, by which the heat storage and heat exchange ratio can be obtained through calculation. The heat storage and heat exchange ratio serves as a unified evaluation standard between different types of heat storage and heat exchange devices, and can achieve accurate measurement of the overall performance of different types of heat storage and heat exchange devices, so that performance comparison can be made between heat storage and heat exchange devices of different parameters and types, providing data support for performance improvement and optimization of different types of heat storage and heat exchange devices.

[0051] For further information, see Figure 2 , the conveying mechanism includes a first valve body 11, a conveying pump 12, and a second valve body 13, which are electrically connected to the control device respectively; the exhaust mechanism includes a third valve body 21, a fourth valve body 22, and a fifth valve body 23, which are electrically connected to the control device respectively; the input port of the first valve body 11 is used to connect to an external water supply device 41, the output port of the first valve body 11 is connected to the input port of the second valve body 13 through the conveying pump 12, the output port of the second valve body 13 is used to connect to the inlet of the heat storage and heat exchange device 42 to be tested, the input port of the third valve body 21 is used to connect to the outlet of the heat storage and heat exchange device 42 to be tested, the first output port of the third valve body 21 is connected to the input end of the detection mechanism through the fifth valve body 23, the second output port of the third valve body 21 is connected to the input port of the fourth valve body 22, and the output port of the fourth valve body 22 is used to connect to an external collection device; the control adjusts the working state of the conveying mechanism and the exhaust mechanism so that the heat storage and heat exchange performance detection system switches to the heat storage mode, specifically including:

[0052] 101. The first valve body 11 and the second valve body 13 included in the control delivery mechanism are closed, and the delivery pump 12 stops working;

[0053] 102. Control the first output port of the third valve body 21 and the fifth valve body 23 included in the exhaust mechanism to be closed, control the input port and the second output port of the third valve body 21 to be opened, control the fourth valve body 22 to be opened, and switch the heat storage and heat exchange performance detection system to the heat storage mode.

[0054] Furthermore, when the temperature of the heat storage material of the heat storage and heat exchange device 42 to be tested meets the preset temperature rise condition, the timing is stopped to obtain the temperature rise time, which specifically includes:

[0055] 201. When the temperature of the heat storage material of the heat storage and heat exchange device 42 to be tested is ≥ the preset heating temperature, stop timing;

[0056] 202. Record the time required for the heat storage material to heat up from room temperature to a preset heating temperature to obtain the heating time.

[0057] In this embodiment, when the heat storage mode is executed, first ensure that there is sufficient water in the water supply device 41; then control the heater of the heat storage and heat exchange device 42 to be tested to start working, and start timing when the heating power of the heat storage and heat exchange device 42 to be tested is ≥ the preset power value P; since the heat storage and heat exchange device is equipped with a temperature protector, the heat storage material in the heat storage heating device to be tested will gradually heat up, and when the temperature of the heat storage material is ≥ the preset heating temperature t1, the temperature protector will cut off the circuit, and the heat storage and heat exchange device 42 to be tested will stop working; record the time required for the heat storage material to heat up from room temperature to the preset heating temperature, and obtain the heating time, which is set as T1. The smaller T1 is, the better the heating performance of the heating body and the better the thermal conductivity of the heat storage material.

[0058] Furthermore, in the present embodiment, when the heat storage mode is executed, ensure that the second output port of the third valve body 21 is always in an open state. Since the straight heat exchange tubes of the heat storage heat exchange device are in contact with the heat storage material, if the design temperature of the heat storage material is higher than 100°C, the water retained in the straight heat exchange tubes will be heated into water vapor. The water vapor needs to be discharged from the outlet of the heat storage heat exchange device 42 to be tested, the second output port of the third valve body 21, and the fourth valve body 22 to an external collection device in sequence to ensure the stability and safety of the entire detection process.

[0059] Furthermore, the control adjusts the working states of the conveying mechanism and the exhaust mechanism so that the heat storage and heat exchange performance detection system switches to the exhaust mode, specifically including:

[0060] 301. The first valve body 11 and the second valve body 13 included in the control delivery mechanism are opened, and the delivery pump 12 starts to work;

[0061] 302. Control the exhaust mechanism to close the first output port of the third valve body 21 and the fifth valve body 23, control the input port and the second output port of the third valve body 21 to open, control the fourth valve body 22 to open, and switch the heat storage and heat exchange performance detection system to the exhaust mode.

[0062] In this embodiment, when the exhaust mode is executed, the delivery pump 12 delivers the water in the water supply device 41 to the interior of the heat storage and heat exchange device 42 to be tested, and the heat storage and heat exchange device 42 to be tested preheats the water for the first time. The high-temperature fluid is discharged from the outlet of the heat storage and heat exchange device 42 to be tested, the second output port of the third valve body 21, and the fourth valve body 22 to the external collection device in sequence; because this part of the high-temperature fluid may still be water vapor exceeding 100°C, the exhaust mode is set to discharge the high-temperature water vapor, thereby ensuring the stability and safety of the detection process.

[0063] Furthermore, after the exhaust is completed, the working states of the conveying mechanism and the exhaust mechanism are controlled and adjusted so that the heat storage and heat exchange performance detection system is switched to the heat release mode, which specifically includes the steps of:

[0064] 401. Obtaining the outlet temperature of the heat storage and heat exchange device 42 to be tested. When the obtained outlet temperature is less than the preset heat release stop exhaust temperature, it indicates that the exhaust is completed;

[0065] In this embodiment, the preset heat release stop exhaust temperature is 99°C.

[0066] 402. The first valve body 11 and the second valve body 13 included in the control delivery mechanism are opened, and the delivery pump 12 starts to work;

[0067] 403. Control the second output port of the third valve body 21 and the fourth valve body 22 included in the exhaust mechanism to be closed, control the input port and the first output port of the third valve body 21 to be opened, control the fifth valve body 23 to be opened, and switch the heat storage and heat exchange performance detection system to the heat release mode.

[0068] For further information, see Figure 2 The detection mechanism includes a water intake, and a weighing device 32 for measuring the water volume and a temperature measuring device 31 for detecting the water temperature are arranged in the water intake; the control detection mechanism starts working, and performs heat release timing, obtains the detection result fed back by the detection mechanism, and when the detection result meets the preset heat release condition, stops timing, and obtains the heat release time, which specifically includes:

[0069] 501. The control detection mechanism starts working and executes the heat release timing;

[0070] 502. Obtain the real-time water output fed back by the weighing device 32 at the time of executing the heat release timing, and set it as Q;

[0071] 503. When the real-time temperature fed back by the temperature measuring device 31 is less than or equal to the preset heat release temperature, stop timing;

[0072] 504. Record the time required for the real-time temperature to drop to the preset exothermic temperature to obtain the exothermic time.

[0073] In this embodiment, when the heat release mode is executed, the delivery pump 12 delivers the water in the water supply device 41 to the inside of the heat storage and heat exchange device 42 to be tested, and the heat storage and heat exchange device 42 to be tested heats the water. The high-temperature fluid is output to the water intake from the outlet of the heat storage and heat exchange device 42 to be tested, the first output port of the third valve body 21, and the fifth valve body 23 in sequence, and the detection result is obtained by the weighing device 32 and the temperature measuring device 31 arranged in the water intake; when the real-time temperature is ≤ the preset heat release temperature t2, the timing is stopped; the time required for the real-time temperature to drop to the preset heat release temperature is recorded to obtain the heat release time, which is set to T2. The larger T2 is, the better the heat storage and heat exchange performance of the heat storage and heat exchange device 42 to be tested is.

[0074] In this embodiment, the heat storage and heat exchange ratio can be calculated by the following formula:

[0075]

[0076] Among them, η is the heat release and heat storage heat exchange ratio, the unit is L / W; Q is the real-time water output, the unit is L; α is the outlet water temperature correction coefficient, dimensionless, and takes values ​​according to different numbers of heat storage combination groups: 0.6-1.3; t2 is the preset heat release temperature, the unit is ℃; γ is the heat release time correction coefficient, dimensionless, and takes values ​​according to different outlet water temperature design values ​​of heat storage and heat exchange devices: 0.75-0.90; T2 is the heat release time, the unit is s; P is the preset power value, the unit is watt; δ is the heating time correction coefficient, dimensionless, and takes values ​​according to different types of heating bodies: 0.5-2.5; T1 is the heating time, the unit is s; β is the thermal storage material design temperature correction coefficient, dimensionless, and takes values ​​according to different types of thermal storage materials: 0.35-1.95; t1 is the preset heating temperature, the unit is ℃.
