  • The chamber is constructed with a heavy-duty framework, typically fabricated from corrosion-resistant aluminum alloy or stainless steel, to withstand the long-term effects of harsh climate testing. The exterior is engineered to be highly durable and resistant to UV radiation, ensuring its integrity even after extended exposure to sunlight. The interior is lined with a reflective and thermally conductive material that maximizes the absorption and dissipation of heat, facilitating uniform temperature distribution. The door is designed with a reliable sealing mechanism, incorporating a high-quality gasket and a multi-point locking system, ensuring an airtight enclosure. It also features a viewing window made of toughened, UV-resistant glass, allowing for visual inspection of the testing process while maintaining the chamber's environmental integrity.
• Precision Climate Control Systems
  • Temperature Control: Capable of maintaining a wide temperature range, from -40°C to +85°C, with an exceptional accuracy of ±0.5°C. It utilizes advanced refrigeration and heating technologies, such as vapor compression refrigeration and high-power electric heaters. The control system incorporates a sophisticated feedback loop, with multiple temperature sensors strategically placed throughout the chamber, ensuring uniform temperature distribution and minimal temperature gradients. The user-friendly control panel allows for precise programming of temperature profiles, including ramp rates, dwell times, and cycling sequences, enabling the replication of complex real-world temperature variations, such as the rapid temperature drops during a desert night or the heat buildup in a sunny afternoon.
  • Humidity Control: The humidity control system is equally precise, capable of achieving humidity levels from 0% to 100% RH (Relative Humidity), with an accuracy of ±3% RH. It employs a combination of steam humidifiers and desiccant dehumidifiers, along with a carefully designed air circulation system. The chamber is equipped with humidity sensors that continuously monitor the internal humidity, and the control system adjusts the humidification or dehumidification processes accordingly. This allows for the creation of stable and dynamic humidity environments, mimicking the diverse moisture conditions that photovoltaic products may face, from the arid and dry deserts to the humid and rainy coastal regions. The system also includes a condensate removal mechanism to prevent any water accumulation within the chamber, safeguarding the tested samples and the chamber's internal components.
  • UV Radiation Simulation: To replicate the harmful effects of sunlight, the chamber is equipped with a high-intensity UV radiation source. The UV spectrum and intensity can be precisely adjusted to match the solar irradiance levels specified in the IEC 61215 standard. This enables the evaluation of how photovoltaic materials and components degrade over time due to UV exposure, such as the yellowing and embrittlement of encapsulation materials or the loss of efficiency in solar cells.
• Advanced Instrumentation and Data Acquisition
  • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. In addition to temperature, humidity, and UV sensors, it includes irradiance sensors to measure the intensity of the UV radiation and light sensors to monitor the visible light spectrum. These sensors are connected to a state-of-the-art data acquisition system that records and stores all the relevant data. The data acquisition system offers a high sampling rate, typically ranging from 50 to 500 samples per second, ensuring that even the most rapid changes in climate parameters are accurately captured. The collected data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The system is also compatible with photovoltaic-specific data analysis software and can generate detailed reports and graphs, facilitating the interpretation and communication of test results.
• Compliance with IEC 61215 and Safety Features
  • The Customized Climate Test Chamber is designed and manufactured to meet the specific requirements of the IEC 61215 standard.

It also has a power failure recovery function, which allows the chamber to resume the test operation automatically once the power is restored, ensuring the integrity of the test sequence. The interior lighting is designed to be explosion-proof and suitable for use in a humid environment. The chamber is also equipped with a fire suppression system, which can quickly extinguish any potential fires that may occur during the test. Additionally, the control panel includes built-in alarms and indicators, which alert the operator in case of any abnormal conditions or system malfunctions.

3. Specific Parameters

• Chamber Size and Capacity: Available in various sizes to accommodate different photovoltaic products. The volume can range from a few cubic feet for testing small solar cell samples or individual components to several hundred cubic feet for large photovoltaic modules or complete inverter systems. The interior dimensions are optimized for proper air circulation and uniform climate parameter distribution, ensuring that all parts of the sample are effectively tested.
• Temperature Cycling Rate: Can perform temperature cycles at a rate of several cycles per day, depending on the specific requirements of the IEC 61215 test protocol. For example, it can conduct 2 to 4 cycles per day between -20°C and +60°C, subjecting the sample to repeated and rapid thermal stress, which is essential for evaluating the equipment's resistance to thermal fatigue and its ability to function reliably in fluctuating temperature environments.
• Humidity Cycling Rate: The humidity can be cycled at a rate that allows for the simulation of rapid changes in moisture conditions. The chamber can adjust the humidity levels within a short period, typically within 10 to 30 minutes, depending on the desired test scenario, replicating the sudden humidity shifts that may occur in different climates, such as the transition from a dry morning to a humid afternoon in a tropical region.
• UV Radiation Intensity and Duration: The UV radiation source can emit radiation with an intensity ranging from 0 to 1.5 W/m², and the exposure duration can be precisely controlled from a few hours to several weeks, depending on the specific test requirements. This enables the accurate simulation of the cumulative UV damage that photovoltaic products may experience over their lifetime.
• Data Acquisition Rate: The data acquisition system can sample sensor data at a rate of 100 samples per second, ensuring that even the most minute and rapid changes in temperature, humidity, UV radiation, or other parameters during the test are accurately recorded and can be analyzed in detail. This high sampling rate provides valuable insights into the performance and potential failure modes of the photovoltaic products.
• IEC 61215 Standard Compliance: Complies with all the relevant clauses and procedures of the IEC 61215 standard, including the specific climate profiles, test durations, and sample preparation methods. This ensures that the testing is conducted in a consistent and recognized manner, facilitating market access and compliance with regulatory requirements for photovoltaic products.

4. Product Functions

• Accurate Simulation of Photovoltaic Operational Environments
  • The primary function of this test chamber is to provide a highly accurate and realistic simulation of the climate conditions that photovoltaic products will face.
