Description

Technical Field

[0001] The present invention relates to the technical field of BIPVT component performance detection, and in particular to a synchronous testing device and a testing method for photovoltaic-thermal building integrated components. Background Art

[0002] Building Integrated Photovoltaic / thermal (BIPVT) technology uses BIPVT components as part of the building envelope, while providing clean electricity and heat for the building, saving materials and meeting the building's energy needs. BIPVT components, when used as envelope structures in combination with buildings, must simultaneously meet the thermal insulation performance of the envelope structure, the electrical and thermal properties of photovoltaic components. In addition, the design of the flow channel must also be considered during the application of the components. Clarifying the pressure drop under different flow rates can provide a basis for pipeline design. Corresponding to the above issues, the thermal resistance, heat transfer coefficient, electrical efficiency, thermal efficiency and pressure drop of BIPVT components under different operating conditions can provide a basis for the design of BIPVT components combined with buildings.

[0003] BIPVT components are composed of multiple layers of different materials, usually including photovoltaic cell layers, heat exchange structure layers, insulation layers, backboard layers, etc. The internal fluid flow and heat transfer process are different from conventional building exterior insulation and exterior finishing materials, and are more complex. The performance of the component is affected by multiple factors such as the material characteristics of each layer, the fluid characteristics in the heat exchange structure, the fluid temperature and flow rate, the insulation layer material and thickness, solar irradiance, ambient temperature, and installation angle. As a new type of building component, obtaining the comprehensive performance parameters of BIPVT components is of great significance for the application of components in actual projects. Designers can comprehensively design the building envelope structure according to the thermal resistance / heat transfer coefficient of the component to meet the energy-saving requirements of the envelope structure.

[0029] BIPVT (Building Integrated Photovoltaic Thermal) component testing refers to a series of test procedures to evaluate the performance of photovoltaic thermal (PV / T) systems integrated in buildings. These tests are designed to ensure the safety, reliability and efficiency of BIPVT systems in practical applications. BIPVT systems can not only generate electricity, but also provide thermal energy for heating or hot water supply in buildings, so they play an important role in green buildings and sustainable energy solutions.

[0030] BIPVT component test systems usually need to simulate various natural environmental conditions, such as temperature, humidity, and sunlight intensity, to evaluate the long-term performance of components. Key parameters of the test system include spectral matching, irradiance adjustment capability, cell calibration mode, and adaptive scanning function of smart electronic loads. These parameters ensure the accuracy and applicability of the test results in order to predict the performance of BIPVT components in different building integration environments.

[0031] Embodiments that can be added to the present invention are:

[0032] Robotic Arm:

[0033] A robotic arm is an automated device that mimics the functions of a human arm. It is usually composed of multiple joints that can rotate and move along different axes. The working principle of a robotic arm involves knowledge from multiple engineering fields such as kinematics, dynamics, and control algorithms.

[0034] The robot arm realizes the position and posture control of the end effector through the movement of each joint. The kinematics principle involves the calculation of forward kinematics and inverse kinematics to determine the movement of each joint of the robot arm, and then calculate the exact position and posture of the end effector in space.

[0035] During the movement of the robot arm, its force and dynamic response need to be considered. The principles of dynamics, including the Newton-Euler equation and the Lagrange equation, are used to describe the motion state and force relationship of the robot arm, which is crucial to ensure that the robot arm can operate safely and reliably.

[0036] In order to achieve precise control of the robot arm, a suitable control strategy needs to be adopted. Common control principles include position control, speed control, force control, etc., as well as model-based control methods and intelligent control algorithms. The control system receives instructions from the operator or preset program, and completes specific tasks by moving the joints of the actuator in the required order, along a determined position or trajectory.

[0037] The design key points of the robot arm include joint design, structural design, end effector design and control system design. Joint design affects the range of motion and flexibility of the robot arm; structural design needs to consider strength, stiffness and stability; end effector design is carried out according to different application requirements, which can be grippers, suction cups, welding guns, etc.; control system design includes hardware and software. The hardware part includes controllers, drivers and sensors, etc., and the software part includes control algorithms and human-machine interfaces, etc.

[0038] The working principle of the robotic arm is a complex system engineering that relies on precise kinematic and dynamic calculations, as well as advanced control strategies to achieve efficient and precise automated operations.

[0039] Constant temperature and humidity chamber:

[0040] Constant temperature and humidity chamber is an environmental simulation equipment commonly used in industry and scientific research. It can provide stable temperature and humidity conditions for testing and evaluating the performance and reliability of materials, components, equipment, etc. in specific environments. These devices are usually suitable for product quality testing in industries such as electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical treatment, and aerospace. Constant temperature and humidity chambers can perform a variety of environmental simulation tests such as high temperature, low temperature, alternating humidity and heat, and constant humidity and heat to ensure the adaptability and stability of products under different environmental conditions.

[0041] The technical parameters of the constant temperature and humidity chamber include temperature range, humidity range, temperature and humidity control accuracy, temperature and humidity fluctuation, heating and cooling rate, etc. For example, the temperature control range of some constant temperature and humidity chambers can be from -70℃ to 150℃, the humidity control range can be from 15%RH to 98%RH, the temperature control accuracy can reach ±0.1℃, and the humidity fluctuation can reach ±1.5%RH.

[0042] Manufacturers of constant temperature and humidity chambers offer a variety of models and specifications to meet the needs of different customers. These products not only differ in performance, but also have been optimized and improved in terms of control systems, humidification methods, refrigeration systems, safety devices, etc. For example, some constant temperature and humidity chambers are equipped with advanced technologies such as intelligent PID temperature control systems, upgraded humidification systems, variable frequency refrigeration systems, capacitive humidity sensors, etc., to provide a more accurate and reliable test environment.

[0043] Electric stand:

[0044] Powered mounts are mounts with electric adjustment features that can be used for a variety of devices, such as cameras, mobile phones, monitors, etc. They usually provide automatic adjustment, clamping and other functions to facilitate users to fix and move equipment. Powered mounts are designed to provide more stable and reliable support, especially when the vehicle is in motion, to ensure the safe and stable placement of the device.

By collecting the volt-ampere characteristic curve of the solar cell to be tested, its maximum power, maximum power point current, maximum power point voltage, short-circuit current, open-circuit voltage, fill factor, photoelectric conversion efficiency and other parameters are calculated. These parameters can not only reflect the electrical performance of solar cells and are used for production process research, but also for solar cell power and grade assessment as a pricing basis for sales.

[0047] Constant temperature and humidity air conditioning equipment:

[0048] Constant temperature and humidity air conditioner is a kind of air conditioning equipment specially designed to control indoor temperature and humidity. It is suitable for places with strict requirements on environmental conditions, such as electronic equipment manufacturing, drug storage, laboratories, precision processing, etc. This type of air conditioning equipment usually has high-precision temperature and humidity control capabilities, which can ensure the stability of the indoor environment and prevent environmental changes from affecting products or experimental results.

[0049] Constant temperature and humidity air conditioning systems usually consist of three parts: a refrigerant circulation system, an air circulation system, and an electrical automatic control system. The refrigerant circulation system is responsible for absorbing and releasing heat through the evaporation and condensation process to achieve air cooling and dehumidification; the air circulation system is responsible for transporting the treated air into the room and mixing it with the indoor air; the electrical automatic control system is the brain of the entire system, responsible for monitoring and adjusting the operation of the system to achieve the preset temperature and humidity targets.

[0050] Thermal Radiation Shield Temperature Sensor:

[0051] A thermal radiation shielded temperature sensor is a device that can measure the temperature of an object by using the thermal radiation emitted by the object according to the temperature. This type of sensor usually does not require direct contact with the object being measured, so it is suitable for measuring the temperature of moving objects or measuring temperature in high temperature environments. Thermal radiation shielding may refer to the technology used in sensor design to reduce the impact of ambient thermal radiation on the measurement results and improve the accuracy of the measurement.

[0052] Radiation-proof temperature sensor:

[0053] Radiation-proof temperature sensors are temperature measurement devices specially designed to reduce or eliminate the effects of electromagnetic radiation. Such sensors are particularly important for equipment and systems operating in high temperature, high pressure, and strong radiation environments, such as nuclear reactors, aerospace, and military equipment. They usually have special designs, such as shielding with specific materials, optimized geometry to reduce heat transfer efficiency, etc., to protect the sensor from the effects of radiation.

[0054] IV characteristic tester:

[0055] An IV characteristic tester is a device used to measure the current output of electronic devices or solar cells at different voltages. This tester can draw an IV curve, i.e., a current-voltage characteristic curve. By analyzing these curves, the performance parameters of the device can be evaluated, such as open circuit voltage, short circuit current, maximum power point, etc. IV characteristic testers are widely used in the research and development, production, quality control, and performance evaluation of photovoltaic modules.

[0056] There are many types of IV characteristic testers on the market, which have different functions and technical features, such as high-precision measurement, wide-range testing, automated testing, data analysis and processing, safety protection, etc. In addition, some testers also integrate temperature control functions to meet international standard test conditions, and provide graphical interface software to make operation more convenient.

[0057] Data logger:

[0058] A data acquisition system (DAS) is a device used to capture analog or digital signals and convert them into electrical signals. It is usually used to convert sensor data into a form that can be processed by a computer. They are widely used in industrial automation, environmental monitoring, healthcare and other fields. The basic functions of a data acquisition system include data acquisition, processing, storage and transmission.

[0059] Terminal equipment:

[0060] Terminal devices generally refer to devices connected to a computer system for receiving, sending or processing data. They can be physical devices, such as a computer monitor, printer, keyboard, mouse, etc., or remote devices connected through a network, such as a remote computer or a dedicated network terminal. Terminal devices are the medium through which users interact with computer systems. They can be independent devices or part of a computer system.

[0112] Embodiment 2

[0113] The difference between this embodiment and the first embodiment is that, in order to facilitate the testing of the performance of the fluid in the BIPVT component 7 under different tilt angles, a motor is installed on the opposite outer wall of the electrically adjustable and movable insulating frame 6, and the output shaft of the motor penetrates the electrically adjustable and movable insulating frame 6 and extends into the inner wall of the electrically adjustable and movable insulating frame 6. One end is fixedly connected to the inner frame, and the inner frame is detachably connected to the BIPVT component 7. The inner frame is rotatably connected to the electrically adjustable and movable insulating frame 6, so that the inner frame drives the BIPVT component 7 to rotate in the electrically adjustable and movable insulating frame 6. At the same time, in order to facilitate the BIPVT component 7 to adjust the angle by rotation, the inlet 37 and the outlet 38 of the BIPVT component 7 are respectively connected to the conveying device 20 through a telescopic hose; when testing, the solar simulator 4 and the BIPVT component 7 maintain synchronous angle adjustment, so that the solar simulator 4 and the BIPVT component 7 are in a parallel state, and the performance of the fluid in the BIPVT component 7 under different tilt angles can be tested.
