1Step in ice cover simulation test chamberSystem Composition

1. Box body: Adopting insulation structure to effectively control internal temperature and reduce heat loss. The box is equipped with multiple climate control components, which can simulate various climate conditions such as freezing rain, frost, and wind speed.

2. Lift turntable: The design is flexible, and the height and angle can be adjusted according to the needs of the experiment, adapting to different types and sizes of test samples. During the experiment, the test sample is placed on a lifting platform and adjusted to appropriate temperature and humidity conditions.

3. Spray water supply system: Spray water droplets through precision nozzles, and the droplets quickly freeze in a low-temperature environment, forming an ice layer. The spray system can adjust the size and spray amount of water droplets to simulate different precipitation intensities (such as drizzle, moderate rain, rainstorm, etc.). The nozzle is usually made of anti freezing materials to ensure long-term stable operation in low-temperature environments.

4. High pressure gas source and supply system: Mist the water vapor and cooperate with the spray system to gradually freeze the water on the surface of the sample under predetermined temperature and humidity conditions, forming an ice cover.

5. Temperature regulating device: Equipped with an efficient refrigeration system, it can quickly lower the temperature inside the box below freezing point (usually -40 ° C to 0 ° C) to simulate extremely cold environments. The temperature control system usually adopts PID (proportional integral derivative) algorithm to ensure the accuracy and stability of temperature regulation, and avoid the influence of temperature fluctuations on experimental results. In some advanced devices, rapid temperature rise and fall functions can also be implemented to simulate sudden temperature changes in nature.
