Product Details

Rapid temperature and humidity test chamberworking principle

The working principle of the rapid temperature change test chamber is based on the reverse Carnot cycle, which achieves rapid temperature changes through the circulation of components such as compressors, condensers, valves, and evaporators. The equipment is equipped with heating and cooling systems inside, which regulate the temperature inside the box through the control system to ensure the accuracy and stability of temperature changes. In addition, the device is equipped with an excellent temperature control system that can monitor and adjust the temperature inside the box in real time, ensuring that temperature fluctuations are within the set range.
