The testing device and the testing method have good scalability and can be upgraded and improved according to new test requirements and technological developments.

[0069] Please continue to see Figure 2 The test method provided by the second embodiment of the present invention is mainly used to evaluate the photothermal and photoelectric performance of the integrator to be tested 108. The method simulates different test environments by adjusting one or more working parameters of the air handling component 102, the wind speed adjustment component 104 and the light adjustment component 106, and detects the performance changes of the integrator to be tested 108 through the photoelectric test component and the photothermal test component.

[0070] Step 10, selecting the operating parameters that need to be adjusted, which may include the temperature and humidity control of the air treatment component 102, the wind speed setting of the wind speed adjustment component 104, and the light intensity and spectral distribution of the light adjustment component 106.

[0071] According to the test requirements, the values ​​of the selected parameters are gradually adjusted to simulate different test environments. For example, the parameters of the air handling component 102 can be adjusted to simulate different climate conditions, the parameters of the wind speed adjustment component 104 can be adjusted to simulate different wind speed conditions, or the parameters of the light adjustment component 106 can be adjusted to simulate different light conditions.

[0072] Step 20, while adjusting the parameters, monitor the performance changes of the integrator 108 to be tested in real time through the optoelectronic test assembly and the photothermal test assembly. The optoelectronic test assembly may include a solar controller, a load, a voltage and a current tester, etc., for detecting the performance indicators such as the optoelectronic conversion efficiency and stability of the integrator 108 to be tested. The photothermal test assembly may include a thermometer, a flow meter 138, a thermal imager, etc., for detecting the performance indicators such as the optoelectronic conversion efficiency, thermal stability and temperature distribution of the integrator 108 to be tested.

[0073] According to one embodiment of the present invention, the step of detecting the photothermal and photoelectric performances of the integrator 108 to be tested by using the photoelectric testing assembly and the photothermal testing assembly includes: The total efficiency of the integrator 108 to be tested is calculated according to the following formula: or = or gd + or gr or is the total efficiency of the integrator 108 to be tested, %; or gd is the photoelectric conversion efficiency of the photoelectric test component, %; or gr is the thermal collection efficiency of the photothermal test component, %.

[0074] In the embodiment of the present invention, the steps of detecting the photothermal and photoelectric performances of the integrator to be tested 108 by using the photoelectric testing assembly and the photothermal testing assembly are further refined, especially by introducing a calculation formula for the total efficiency.

[0075] According to the test requirements, the operating parameters of the air handling component 102, the wind speed adjustment component 104 and the light adjustment component 106 are adjusted. It is ensured that all adjusted parameters remain stable during the test to simulate a stable test environment.

[0076] The photoelectric performance data of the integrator 108 to be tested, including voltage, current, power, etc., are collected through the photoelectric test component for calculating the photoelectric conversion efficiency. The photothermal performance data of the integrator 108 to be tested, including the inlet and outlet water temperature and water flow rate of the collector, etc., are collected through the photothermal test component for calculating the thermal collection efficiency.

[0077] All performance data are recorded in real time, and preliminary data processing and analysis are performed to evaluate the performance of the integrator 108 under test.

[0078] When calculating the total efficiency of the integrator 108 under test, the following formula is used: or = or gd + or gr in: or is the total efficiency of the integrator 108 to be tested, which represents the total efficiency of the integrator in converting light energy into electrical energy and thermal energy.

[0079] or gd The photoelectric conversion efficiency of the optoelectronic test component indicates the efficiency of the integrator in converting light energy into electrical energy.

[0080] or gr It is the thermal collection efficiency of the photothermal test component, which indicates the efficiency of the integrator in converting light energy into heat energy.

[0081] According to the data collected by the optoelectronic test assembly, the actual output power of the integrator to be tested 108 is calculated, and the rated power of the integrator under standard light source conditions (such as irradiance and temperature under standard test conditions) is used as a reference.

[0082] Calculate the photoelectric conversion efficiency or gd , the formula is: or gd = Actual output power Rated power × 100% According to the data collected by the photothermal test assembly, the actual heat collection amount of the integrator to be tested 108 is calculated, and the heat collection amount under standard test conditions is used as a reference (such as standard irradiance, water temperature difference, etc.).

[0083] Calculate the collector efficiency or gr , the formula is: or gr =Actual heat collection standard heat collection × 100% The calculated photoelectric conversion efficiency orgd and thermal efficiency or gr Substituting into the total efficiency formula or = or gd + or gr In the example, the total efficiency of the integrator 108 to be tested is calculated.

[0084] Based on the calculated total efficiency, the comprehensive performance of the integrator under test 108 is evaluated. The test results are compared with expected targets, industry standards or competitive products to understand the performance advantages and room for improvement of the integrator under test 108.

[0085] According to an embodiment of the present invention, the operating parameters include at least temperature, humidity, wind speed and irradiance.

[0086] In the embodiment of the present invention, the operating parameters of the photothermal-photovoltaic integrator test device are specifically and thoroughly defined. These operating parameters play a vital role in the test process, and they can simulate different environmental conditions, thereby comprehensively and accurately evaluating the performance of the integrator 108 to be tested.

[0087] Temperature is one of the key factors affecting the performance of the integrator. Different temperature conditions may cause changes in the photovoltaic conversion efficiency and heat collection efficiency of the integrator. During the test, the temperature of the test environment is precisely controlled by the air handling component 102, which can simulate the climatic conditions of different seasons and different geographical locations, and then evaluate the performance stability of the integrator at different temperatures.

[0088] Humidity also has a significant impact on the performance of the integrator. A high humidity environment may cause condensation on the surface of the integrator, affecting the photoelectric conversion efficiency; at the same time, humidity may also affect the heat transfer efficiency of the collector. By adjusting the humidity of the test environment through the air handling component 102, humid or dry climate conditions can be simulated to evaluate the performance of the integrator under different humidity conditions.

[0089] Wind speed is an important factor affecting the heat dissipation performance of the integrator. In an environment with higher wind speed, the heat dissipation effect of the integrator may be better, thereby reducing the operating temperature and improving the photoelectric conversion efficiency and heat collection efficiency. By accurately controlling the wind speed of the test environment through the wind speed adjustment component 104, the performance under different wind speed conditions can be simulated, providing an optimization basis for the heat dissipation design of the integrator.

[0090] Irradiance is a key indicator for evaluating the photoelectric performance of the integrator. Different irradiance conditions will directly affect the photoelectric conversion efficiency of the integrator. The light adjustment component 106 can simulate light conditions with different light intensities and spectral distributions, thereby evaluating the performance stability and photoelectric conversion efficiency of the integrator under different irradiances.

[0091] During the test, the values ​​of these operating parameters can be flexibly adjusted according to actual needs to simulate different test environments. By real-time monitoring and recording the performance data of the integrator 108 under different operating parameters, its performance can be comprehensively evaluated and strong data support can be provided for subsequent improvement and optimization.

[0092] In addition, advanced testing technologies and data analysis methods can be combined to further improve the accuracy and reliability of the test. For example, high-precision sensors and data acquisition systems can be used to monitor and record performance data in real time; data analysis software can be used to process and analyze test data to extract key performance indicators and trends; and targeted improvement suggestions and optimization plans can be proposed based on test results.
