1. Equipment usage
The ice accumulation and freezing rain test chamber is used to simulate the test conditions of low-temperature ice accumulation environment. This equipment adopts a touch control system and has independent test functions such as high and low temperature, low temperature ice accumulation, etc.
Meets GJB150.22A-2009. DL/T1247, ice accumulation and freezing rain test standards for equipment environmental test methods.
2. Equipment working principle
This equipment is composed of a working room and a closed test area. The temperature and humidity are controlled by the heater and refrigeration system through the air circulation through the balanced temperature and humidity control method (BTHC). The instrument then performs PID operation for closed-loop control to maintain the temperature and humidity. Reach the set control range. In addition, according to the test requirements, simulation tests such as ice accumulation, freezing rain, and rain can be conducted separately to meet the purpose of combining different test items.
