Principle
The equipment achieves rapid temperature change and uniform distribution through multi-channel mechanical compression refrigeration system and multi-stage throttling system, combined with intelligent control to automatically adjust the refrigeration output and capillary tubing throttling. The broadband compression equilibrate temperature regulation 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. Fast convergence temperature control is achieved through PID adaptive algorithm. The humidification system adopts electric boiler humidification and Compressor dehumidification. P.I.D controls the humidification amount to ensure the accuracy of temperature and humidity.
