What the design concept of the freezing rain test chamber?
About the design concept of the accumulation of freezing rain test chamber：
1. The the main function of the freezing rain test chamber
1.1 Simulate the conditions of ice accumulation and freezing rain in the natural environment.
1.2 Provide adjustable temperature, humidity and rainfall intensity.
1.3 Test the performance and reliability of outdoor products such as cables, drones, electric cabinets, automobiles, etc. under the conditions of accumulating ice and freezing rain.
2. Components of this freezing rain test chamber
2.1. Accumulation of ice and freezing rain test box using closed space, usually made of stainless steel material welding, with good thermal insulation performance and water corrosion resistance.
2.2 High and low temperature control: the use of compressor refrigeration, PID automatic arithmetic, regulating the temperature inside the box, simulating the temperature changes in different climatic conditions.
2.3 Humidity control: through the humidification system, you can set the required humidity requirements, simulating the humidity changes under the environment of accumulation of ice and freezing rain.
2.4 Freezing rain system: through the nozzle or spray system to simulate rainfall, you can set different rainfall intensity and time to simulate different degrees of accumulation of ice and freezing rain.
3. Design Principles of freezing rain test chamber
The harsh outdoor environment in the experimental set of real presentation.
4.Precautions of freezing rain test chamber
4.1 Freezing rain usually occurs in a low-temperature environment below 0 ℃, the accumulation of ice and freezing rain test chamber should have a precise temperature control function, the temperature between -40 ~ 50 degrees.
4.2 humidity in the spray state when not controllable, not spray state can be set arbitrarily.
4.3 The time and thickness of icing: design adjustable nozzle or spray system, by controlling the number of nozzles, diameter and spray pressure and other parameters to achieve different rainfall intensity.
4.4. Wind speed simulation: wind speed has an effect on the distribution and morphology of ice accumulation in the freezing rain test. Therefore, the test chamber should be able to simulate different wind speed conditions.
In summary, the temperature, humidity, rainfall intensity, wind speed and time are mentioned above by Huanyi Instrument to achieve a comprehensive simulation and testing of changes in ice accumulation and freezing rain conditions.
