Principle
The equipment automatically adjusts the refrigeration output and flow rate according to the working conditions through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system to achieve rapid temperature change and uniform distribution. The broadband compression equilibrate temperature control system and PID adaptive algorithm are used to ensure the full exchange of hot and cold and uniform air supply to the studio through the forced air duct system of the temperature harmonizing chamber, static pressure chamber and centrifugal fan blade. The control system is continuously revised according to the temperature situation to achieve fast convergence and stable control.
Applications

Steps
1. Ensure that the installation site is flat, well ventilated, free of flammable and explosive gases, and check the Power supply voltage and grounding.
2. Connect the water supply system to ensure that the water quality meets the requirements, and choose the automatic or manual water supply mode.
3. Set the temperature and humidity parameters through the control panel, and you can choose the program mode or the fixed value mode to operate.
4. Start the equipment, monitor the running status, and view real-time data and fault prompts through a graphical interface.
5. After the test is completed, turn off the equipment and disconnect the power supply for daily maintenance.
Notice
• The installation site should be flat and well ventilated to avoid flammable, explosive and corrosive gases.
• Power supply voltage stability, grounding resistance is less than 4Ω.
• The water quality of the water supply must meet the second-level water use standard of the National Analytical Laboratory.
• When the equipment is running, there should be enough maintenance space around.
• Regularly check the refrigeration system and protective devices to prevent excessive temperature or pressure.
• Avoid using the device in extreme environment temperatures (below 5 ° C or above 30 ° C).
