In the field of environmental simulation technology, we have achieved a groundbreaking leap. TEMAK's newly delivered 150m³ Multi-Environment Climatic Chamber successfully enables "time acceleration" within the laboratory – capable of replicating the complete climatic cycle from spring to winter in just a matter of days.
The innovation of this equipment lies not only in its comprehensive functionality but also in its exceptional spatial design and load-bearing capacity. Featuring a 150 cubic meter tesvolume and a robust floor load capacity of ≥3000 kg/m², the chamber can easily accommodate large equipment such as small trucks for testing. This allows clients to conduct full-vehicle level environmental adaptability verification in-lab, eliminating dependencies on seasonal and unpredictable outdoor testing conditions.
The design philosophy of this system is to achieve laboratory-grade, precise replication of multiple climatic stress conditions found in real-world environments. Six core modules operate under a unified control architecture, enabling a leap from independent precision control to complex scenario coordination.
Utilizing high-efficiency refrigeration units and precise PID control algorithms, it establishes a broad and stable temperature range from -30°C to +65°C. Its core strength lies in powerful thermal load handling and precise control. Even under extreme conditions with a full 3000kg test load, the system reliably maintains an average heating/cooling rate of ≥1 K/min throughout the process, ensuring temperature uniformity ≤ 2.0°C, providing a dependable baseline environment for various tests.
Employing multi-stage humidification and dehumidification technologies, it achieves a wide control range of 25% RH to 95% RH within the 25°C to 65°C temperature band. Through high-precision humidity sensors and balanced control logic, the system ensures control stability even under demanding conditions like high temperature and high humidity, meeting the stringent requirements of long-term damp heat tests.
A precision matrix comprising hundreds of solid cone nozzles enables the physical simulation of natural rainfall. With nozzles spaced 200x200mm apart and coupled with staged pressure stabilization and dynamic flow control, the system accurately simulates light, moderate, and heavy rain. Achieving a rainfall uniformity coefficient of 0.8, it fully covers precipitation levels from drizzle to storm.
This system utilizes a unique top spray and low-temperature environment coupling technology. By precisely controlling water droplet size, distribution density, and internal airflow, it forms a uniform and stable ground snow cover within a 3500x4500mm effective area. It can accurately simulate snow cover thickness for light, moderate, and heavy snow, verified through uniformity tests, providing reliable experimental conditions for various snow environment tests.
Constructed with 15 units of 2500W full-spectrum lamps and featuring a movable lamp bank design with zone control strategy, it achieves a continuously adjustable irradiance of 600 - 1200 W/m² within a 4000x3000mm irradiation area. The integrated irradiance monitoring device ensures light uniformity deviation is controlled within ±5%, meeting the needs of various photo-aging and photothermal effect tests.
Equipped with high-performance variable frequency axial fans and utilizing advanced fluid dynamics design and PID control algorithms, it establishes a stable wind velocity field of 5.0 to 20.0 m/s within the test space. Supporting stepless speed regulation with a control accuracy of ±0.5 m/s, the system accurately replicates natural wind environments corresponding to levels 4 to 8 on the Beaufort scale.
The advanced nature of this equipment is reflected in its high degree of system integration and scenario building capability. Based on TEMAK's independently developed industrial control platform, the system achieves centralized management and coordinated control of the six environmental modules.
A 15-inch high-resolution touch screen serves as the HMI, equipped with a 50 program capacity and program linking functions. The controller, through multi-loop PID adjustment and advanced control logic, ensures smooth transitions and precise control of environmental parameters during mode changes, supporting various operating modes like constant value and program combinations.
The system possesses comprehensive data acquisition, storage, and analysis functions. It records all environmental parameters at a sampling frequency of 10 seconds intervals, with a data storage cycle exceeding 10 years. Running curves (image format) and raw data (Excel format) can be exported via the USB interface, providing complete data support for test analysis.
A complete performance verification methodology has been established. Following standards such as GB/T 5170.2, key indicators like temperature uniformity, rainfall uniformity, snow thickness distribution, light intensity, and wind speed control accuracy are systematically verified. This ensures that every environmental stress output by the equipment meets the reliability requirements for engineering applications, providing a credible test environment for product validation.
Through multi-parameter programmable control, the system enables the laboratory replication of complex climatic environments. It can simulate continuous climate scenarios ranging from spring/summer heat and humidity with heavy rain to autumn/winter dryness with wind and snow, supporting automatic continuous operation for up to 28 days. This provides a comprehensive testing platform for product environmental adaptability research.
From the warmth of spring to the harshness of winter, from continuous drizzle to pristine snow cover – the TEMAK 150m³ Full-Function Environmental Simulation System is redefining the boundaries of environmental testing. We are excited to leverage this innovative technology to inject new momentum into the product development cycles of our clients across various industries.
