Walk-in Temperature, Humidity & Light Integrated Test Chamber: Simultaneously Reproducing the Three Factors of Temperature, Humidity, and Light

In the product development process, environmental testing is often the critical factor that determines success or failure. Does the air conditioning system maintain adequate cooling efficiency under high temperatures? Are seals still reliable after high and low-temperature cycles? Will dashboard materials show signs of aging after prolonged light exposure? These are precisely the types of questions that need to be verified and validated in the laboratory before a product can be confidently brought to market.

Techmeco has delivered a custom, non-standard Temperature, Humidity & Light Three-Factor Comprehensive Test Chamber to a leading global enterprise in the engineering machinery sector. This chamber can accurately and simultaneously reproduce the three essential environmental elements: temperature, humidity, and light. Its key advantages are detailed below:

Robust Structure for Superior Insulation

• The chamber features a reinforced overall frame for enhanced durability and stability.

• Insulation Material: High-density, rigid polyurethane foam with a minimum thickness of 150mm and density ≥45kg/m³. It meets stringent fire safety standards, complying with GB/T 8624-2012 B1 (B) or DIN EN 13501-1 B-S1 classifications.

• Interior Lining: Constructed from SUS304 stainless steel with a thickness of ≥1.2mm. Panels are continuously welded to form a perfect seal, effectively preventing moisture ingress into the insulation layer. This robust construction ensures no air leakage or irreversible deformation occurs, even after prolonged exposure to high-temperature, high-humidity, or low-temperature testing.

• Internal Lighting: Equipped with AC220V halogen or LED lamps specifically designed for reliable operation within a -50°C to +80°C environment. The system provides uniform illumination with no dark spots, delivering a minimum illuminance of 150 Lux measured at 1 meter above the floor.

Wide Temperature Range with Stable Humidity Control

• Temperature Range: -50°C to +80°C, covering the vast majority of environmental testing requirements for commercial and industrial products. This range supports validation from cold-start performance in frigid arctic conditions to operational stability testing in extreme heat.

• Temperature Performance (No-Load Conditions): Achieves uniformity ≤ ±2°C and fluctuation ≤ ±1°C.

• Humidity Range: 10% to 95% RH (within a 10°C to 60°C temperature range).

• Humidity Performance (No-Load Conditions): Maintains fluctuation ≤ ±3% RH and uniformity ≤ ±5% RH. This precise humidity control ensures repeatability and reliability in tests sensitive to moisture, such as defrosting and defogging evaluations.

Uniform and Adjustable Light Simulation

• Light Source: Employs imported infrared spectrum lamps, providing continuously adjustable irradiation intensity.

• Irradiation Area: Offers a substantial total exposure area of 12m². The top-mounted array measures no less than 3.3m (W) x 2m (D), while the front-mounted array measures no less than 3.3m (W) x 1.6m (H).

• Adjustable Lamp Frames:

• Front Frame: Angle adjustable between 45° and 75° to accommodate various sample geometries.

• Top Frame: Height electrically adjustable from 2.5m to 3.8m, allowing for flexible positioning relative to the test specimen.

• Irradiation Uniformity & Accuracy: Within a single plane, irradiation uniformity is ≤ ±10%, with an accuracy of ≤ ±25 W/m².

• Lamp Life & Maintenance: Lamp modules are backed by a quality warranty of ≥2000 operational hours. A quick-release design facilitates fast installation or removal as required by specific test protocols.

Data Security with Dual-Redundancy Recording

• Data Logging: Records data at a frequency of no less than 1Hz, capturing temperature, humidity, and monitoring data from all critical subsystems.

• Dual Storage: Features integrated 8GB Flash memory for redundant, simultaneous storage of operational history and test curves. Data is safeguarded against loss during power outages or system anomalies.

• Data Export: An external USB interface supports USB drives up to 64GB for convenient data export in either text or Excel formats.

• Remote Monitoring: Standard interfaces include 485 and CAN bus for seamless integration and uploading of operational status to higher-level data management platforms.

Comprehensive Multi-Level Safety Protection

The Techmeco environmental test chamber is equipped with extensive safety features to ensure reliable and fail-safe operation:

• Power Supply Protection: Protection against undervoltage, overvoltage, phase failure, leakage, and short circuits.

• Heating System Protection: Equipped with circulating fan overload protection and heater short-circuit protection.

• Humidification System Protection: Features water shortage cutoff and overheat protection to prevent dry operation.

• Refrigeration System Protection: Includes compressor over-temperature, over-pressure, and overload protection.

• Lighting System Protection: Integrated black panel temperature monitoring and irradiation intensity limit protection.
