In the reliability testing of new energy, electronic and electrical, aerospace and other fields, the multi-layer high and low temperature humidity test chamber breaks through the limitations of traditional single-chamber equipment by virtue of structural and technological innovations, becoming a core equipment for efficient and accurate environmental simulation testing. Its core features are as follows:
1. Layered Independent Structure to Block Working Condition Interference
• Adopts a vertical layered core structure with 3-5 built-in independent sealed chambers, made of 316L stainless steel for high/low temperature corrosion resistance and deformation resistance.
• High-density thermal insulation materials (thermal conductivity ≤0.023W/(m·K)) are installed between layers, combined with double-channel silicone rubber seals and door gap heating defrost strips to form a strong "thermal barrier".
• Practical tests confirm simultaneous operation of 80℃/95%RH (top layer) and -30℃/30%RH (bottom layer), with inter-chamber interference ≤1%, ensuring the independence and accuracy of multi-variable tests.
2. Parallel Testing Mode to Maximize Efficiency
• Breaks the time-consuming bottleneck of traditional "serial testing" and realizes "spatial parallel testing" upgrade.
• A four-layer equipment can simulate four different temperature and humidity conditions simultaneously; 16 sample groups complete 4-day test volume of ordinary equipment in 8 hours, improving efficiency by 12 times.
• Each chamber is equipped with independent compressors, humidifiers and air duct systems, supporting parallel operation of composite working conditions (constant temperature, alternating, low temperature, etc.), shortening R&D cycles by 30% (verified by new energy enterprises).
3. Dual-Algorithm Precision Control with Excellent Data Stability
• Adopts coordinated control of "PID + fuzzy control" dual algorithms, combined with high-precision capacitive sensors and temperature compensation technology.
• Temperature fluctuation is stabilized at ±0.5℃, humidity deviation ≤±3%RH (up to ±2%RH for some models); multi-directional guide fans and flow equalizing plates eliminate in-chamber temperature gradient, ensuring uniform environmental impact on samples.
• Fuzzy control adjusts refrigeration power quickly for sudden load changes, restoring stable conditions within 3-5 minutes and avoiding test interruption caused by temperature/humidity overshoot.
4. Intensive Energy-Saving Design to Reduce Comprehensive Costs
• Optimized design of "shared main unit + layered frequency conversion" reduces floor area of a three-layer equipment to 35% of three single-chamber equipment; centralized power supply cuts line cost by 40%.
• Frequency conversion module dynamically adjusts power based on chamber load, with total energy consumption 40% lower than same-capacity ordinary equipment and single-unit power ≤5kW.
• Reduces per-batch test cost by over 30% for enterprises, balancing space utilization, energy conservation and operation economy.
5. Intelligent Data Management to Meet Standardized Requirements
• Supports independent storage and on-screen display of layered data, generates "temperature-humidity-layer number" 3D curves, and automatically exports CNAS-certified reports to meet ISO, GB/T and other traceability standards.
• High-end models are equipped with IoT modules for remote monitoring, fault early warning and connection with R&D management systems, reducing material thermal aging rate analysis error from ±8% to ±1.5% and realizing full-process digital test control.
In summary, with the core advantages of "multi-chamber independence, efficient parallelism, precise control and energy-saving intensification", the equipment reconstructs environmental testing logic, provides technical support for product reliability verification, and becomes a key tool for R&D and quality control in high-end manufacturing.
