Climate Chamber

1. Capable of conducting both plant growth environment simulation tests under natural conditions and durability tests for building materials and structures in harsh environments;

2. Chamber net size: ≥16m³;

3. Temperature range: -10℃ to 40℃, with adjustable heating and cooling rates;

4. Temperature accuracy: ±1℃;

5. Humidity range: 45-70% RH;

6. Humidity accuracy: ±2% RH;

7. Light simulation system: Equipped with seven sets of lighting systems, six dedicated adjustable-height plant growth platforms with adjustable and controllable light intensity (0-800 µmol), and one set for building material aging tests with controllable intensity and sinusoidal curve simulation for daily sunlight intensity variations;

8. Light source modules: Red-blue spectrum light source, full-spectrum light source, waterproof rating: IP68;

9. Fresh air system: Built-in air circulation system with controllable wind speed (0-3 m/s) and adjustable wind direction (vertical, parallel, and multiple angles);

10. Dual-redundant independent touchscreen control systems, each with a data acquisition module. Both systems can independently control the climate environment in their zones or operate simultaneously with algorithmic cross-control to simulate complex climate conditions;

11. Users can define no less than 100 test programs, each containing 99 configuration commands. Test programs and configuration commands allow arbitrary setting of parameters such as time, jumps, loops, and cross-operation;

12. Dynamic coordinated programming control for multiple parameters (temperature, humidity, wind speed, etc.) using trigonometric functions (sinusoidal simulation), rectangular, and linear variation modes, as well as constant-value testing for related parameters;

13. The control system includes climate data for more than five cities (user-specified), allowing one-click data retrieval for climate simulation tests of relevant cities;

14. After the test starts, the system automatically generates independent files, enabling real-time storage and display of historical data and curves. Users can set time and data coordinates for curves for convenient viewing, with additional curve selection functionality to customize displayed curves based on test requirements;

15. The chamber features removable stainless steel insulated partitions, allowing physical separation into two zones for independent testing, enabling multi-purpose use of a single unit;

16. The temperature control system uses dynamic heating to avoid local high temperatures and includes independently operated digital temperature control modules to ensure long-term safe operation;

17. Equipped with power-off program memory, automatically resuming and continuing program execution after power restoration;

18. Constructed with stainless steel inner panels and embossed anti-slip floor plates, offering corrosion resistance, anti-slip properties, wear resistance, and a load capacity of up to 2 tons;

19. The refrigeration system uses imported fully sealed compressors, known for high stability, low noise, and long lifespan;

20. Built-in dual-channel self-draining device for autonomous drainage and backflow prevention;

21. Protection devices: Over-temperature protection, water shortage protection, phase sequence protection, high-pressure protection, etc.;

22. A metrology qualification certificate issued by a metrology institution must be provided during equipment acceptance.
