Ice accumulation and freezing rain test equipment is suitable for ice accumulation/freezing rain tests in equipment laboratories. It is mainly used to test the product's resistance to ice accumulation/freezing rain environments, work in ice accumulation/freezing rain environments, and determine the effectiveness of deicing equipment and technology, including The performance of the equipment and methods specified on site is suitable for simulating equipment exposed to ice accumulation conditions caused by freezing rain or drizzle and equipment affected by the accumulation of ice due to seawater splash or zero particles on its operating performance.
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.
