7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit
8. Multi-wing blower with strong air circulation, uniform temperature distribution
9. The heating and cooling systems are completely independent, effectively reducing test costs and failure rates
10. Complete safety protection, including multiple protections such as leakage, short circuit, and over temperature
Principle
The low/high temperature test chamber is designed to achieve a low temperature environment through the refrigeration system using the French "Taikang" fully enclosed Compressor unit and refrigeration system. The heating system uses a nickel-chromium alloy electric heating heater to achieve a high temperature environment. The control system sets and monitors the temperature through the 7.0-inch Touchscreen temperature and humidity control instrument, and uses the P.I.D automatic calculation function to correct the temperature change in real time. The circulation system uses a multi-wing blower to power the air to ensure uniform temperature distribution in the test area. The air circulation design makes the temperature quickly stabilize after opening the door.
