Features
1. Adopt multi-channel environmental protection and energy-saving mechanical compression refrigeration system, the energy consumption is only 80% of the congeneric product, and it is equipped with frequency conversion technology to reduce noise and vibration.
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control to ensure uniform temperature field and small fluctuations.
3, the application of broadband compression equilibrating temperature control system and PID adaptive algorithm to achieve rapid temperature convergence and stability control.
4. Support remote visual control, remote monitoring through RS485 communication, and graphical interface automatically prompts for faults and solutions.
Principle
The test chamber intelligently controls the refrigeration output to adapt to different temperature change rates through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system. Temperature harmonizing chamber, static pressure chamber and centrifugal fan blade forced air duct system are used to ensure full exchange of hot and cold and uniform air supply to the studio. The PID adaptive algorithm continuously corrects the control parameters to achieve rapid convergence and stability of temperature. The remote control system realizes automatic monitoring through human-machine interface and communication interface.
