The walk-in constant temperature and humidity test room is mainly used to simulate complex environmental conditions and test the performance reliability of the entire machine or large components under temperature and humidity changes. It can simulate environments such as low temperature, high temperature, and alternating high and low temperature humidity, and support synchronous testing of the entire machine/vehicle and batch samples. For example, electronic devices need to undergo high-temperature and high humidity testing to verify stability, while automotive components need to verify durability in harsh weather conditions.
The refrigeration system takes away heat and reduces temperature through components such as compressors, condensers, and evaporators; Heating systems generally use electric heating to increase temperature; Humidification system regulates humidity through steam humidification or spray humidification; The circulating air system continuously circulates the air to evenly distribute temperature and humidity, and the various systems cooperate with each other to accurately control the temperature and humidity inside the test room.
structural composition
Shell and Inner Container: The shell is generally processed and formed by stainless steel CNC machine tools, while the inner container is made of imported stainless steel mirror panels, which are corrosion-resistant and easy to clean.
Thermal insulation material: commonly used high-density glass fiber cotton and other materials, the thickness of the insulation layer is generally around 100mm, which can effectively reduce heat transfer and ensure the insulation performance of the laboratory.
Temperature and humidity circulation system: composed of a specially designed low-noise long axis fan motor and a stainless steel multi blade impeller that is resistant to high and low temperatures, it achieves strong convection and vertical diffusion circulation, ensuring uniform distribution of temperature and humidity.
Door and observation window: The door and the box are sealed with double-layer high-temperature resistant high tension sealing strips. The door generally uses non reactive door handles for easy operation. The observation window adopts multi-layer hollow tempered glass, and the inner adhesive sheet conductive film is heated and defrosted for clear observation of the test process.
Core Features
Wide range adjustment capability: The temperature can cover the range of -40 ℃~150 ℃, and the humidity can be adjusted within the range of 20%~98% RH. It can simulate various harsh environments, such as low temperature drying, high temperature and high humidity.
High control accuracy: The temperature control accuracy can reach ± 0.5 ℃, and the humidity control accuracy is ± 2% RH. The temperature and humidity fluctuations during long-term testing are small, ensuring the accuracy and comparability of test results.
Uniformity guarantee: Adopting a multi outlet circulating air supply design and airflow optimization algorithm, the temperature and humidity uniformity of each area in the test room is controlled within ± 2 ℃ (temperature) and ± 5% RH (humidity), suitable for testing large components or multiple samples simultaneously.
