Features
1. Adopt multi-channel environmental protection and energy-saving mechanical compression refrigeration system, energy consumption only accounts for 80% of congeneric products, low noise operation is achieved through frequency conversion technology and sound absorption and silencing design
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control to ensure adjustable flow and uniform temperature field
3, the application of broadband compression equilibrating temperature control system, using fast convergence PID adaptive algorithm to achieve rapid temperature control
4. Configure human-machine management interface and RS485 communication, support remote visual control, with automatic fault prompt and graphical troubleshooting guidance
Principle
The equipment selects the refrigeration path adaptively according to the working conditions through a multi-channel mechanical compression refrigeration system and a self-developed multi-stage throttling system. The broadband compression equilibrate temperature control system is adopted, and the temperature reconciliation 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 control system adopts PID adaptive algorithm to correct the temperature control in real time to achieve fast convergence and stable control.
