Damp Heating Chamber for PV Modules
When evaluating the long-term durability of photovoltaic (PV) modules, exposure to prolonged high temperature and high humidity is essential. LIB's Damp Heating Chamber is specifically designed to simulate the most demanding environmental conditions, delivering highly accurate and repeatable test results. This chamber offers three primary testing modes: Damp Heat, Humidity-Freeze, and Thermal Cycling. Each mode is designed in accordance with international standards to identify potential weaknesses in PV modules prior to real-world application.
【How Can LIB's Damp Heating Chamber Simulate Long-Term Damp Heat Exposure at 85°C and 85% RH?】
Long-Term Damp Heat Exposure for Predictable Module Stability
LIB's Damp Heat Test Chamber is conducted under a controlled environment of 85°C temperature and 85% relative humidity, maintained for 1,000 hours or longer the standards of IEC61215, IEC61646, UL 1703.
With a strict tolerance of ±2°C and ±5% RH, the chamber ensures a highly stable and consistent test environment that aligns with IEC 61215 and other standards for PV module reliability testing.
This method simulates real-world long-term exposure in tropical and humid climates, helping evaluate performance like corrosion.
Advanced Control Systems for Precise Testing Conditions
The damp heat chamber is equipped with a high-accuracy PT-100 Class A sensor and a PID control system, enabling precise environmental monitoring and adjustment in real time.
Its chromium-nickel heating element ensures stable heat distribution up to 85°C, while the humidity control system maintains a balanced environment, reducing fluctuations and enhancing data reliability.
【How Does LIB's Damp heat Chamber Perform Humidity-Freeze Testing Between High Humidity and Extreme Cold?】
Reliable Humidity-Freeze Cycling Method for Sealing and Structural Endurance
The damp heat chamber conducts a multi-phase humidity-freeze cycle according to the standards of IEC61215, IEC61646, UL 1703:
Start at ambient, ramp up to 85°C / 85%RH and hold for 20 hours.
Then rapidly cool to -40°C and hold for 30 minutes.
Return to 25°C with 85%RH and repeat the cycle 10 times.
This process replicates rapid environmental shifts from hot and humid to freezing, testing the PV module's seal integrity, moisture resistance, and mechanical durability.
Eco-Friendly Cooling with Precise Control
Powered by a TECUMSEH compressor, the chamber cools down at a rate of 100°C/h, reaching -40°C efficiently. Also, TECUMSEH compressor can be benefit to buy in your country, which can convenient your test process.
The chamber uses R449A and R508B refrigerants, which ensures environmental responsibility without compromising cooling performance.
【How Does LIB's Damp heat Chamber Deliver Rapid Thermal Cycling Test Between -40°C and 85°C?】
Fast and Efficient Thermal Cycling to Simulate Rapid Temperature Shifts
According to the standards of IEC61215, IEC61646, UL 1703, the Thermal Cycling Test starts at 25°C, drops to -40°C (holding for 10 minutes), then rises to 85°C (holding again for 10 minutes), and returns to 25°C. Each cycle takes less than 6 hours and can be repeated 50–200 times. This demanding test validates the solar modules' ability to withstand harsh thermal conditions, offering you assurance of stable performance and extended service life in real-world environments.
Precision Heating and Cooling for Consistent Results
A PID-controlled 100°C/h heating and cooling system ensures fast and accurate transitions.
Uniform airflow design and high-performance insulation help maintain consistent internal conditions and prevent test deviations.
