2. The self-developed multi-channel and multi-stage throttling system automatically adjusts the capillary tubing throttling through the intelligent control system to ensure adjustable flow and uniform temperature field.
3. The application of broadband compression equilibrate temperature control system, combined with temperature harmonizing chamber and centrifugal fan blades, to achieve uniform temperature distribution, and the PID adaptive algorithm developed in cooperation with South Korea Sanyuan Company to achieve fast convergence, small overshoot, Stability high temperature control.
4. Realize remote visual control, configure human-machine interface and RS485 communication, and support graphical operation, automatic fault prompt, and remote monitoring.
Principle
The test chamber intelligently controls the refrigeration output and flow rate 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 is adopted, combined with the temperature reconciliation chamber and centrifugal fan blades, to force air circulation 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 temperature convergence and stability.

Steps
1. Install the equipment in a flat and well-ventilated site to ensure that the load-bearing capacity is not less than 600kg/m ², and reserve maintenance space.
2. Connect the power supply (AC380V three-phase four-wire system + protective grounding) and check whether the voltage and frequency meet the requirements.
3. Set the temperature and humidity parameters through the touch screen controller, and select the program mode or the fixed value mode to operate.
4, Start equipment, monitor temperature and humidity changes, ensure uniformity and Stability.
5. Use the remote monitoring function to connect to the computer through the RS485 communication interface for real-time control.
6. After the test, turn off the equipment and check for trouble prompts. If necessary, follow the instructions to troubleshoot.
Notice
• The installation site must be free of flammable, explosive, corrosive gases and dust, and away from strong electromagnetic radiation sources.
• Ensure that the ground load-bearing capacity is not less than 600kg/m ², and reserve enough maintenance space (A side is not less than 400mm, B side is not less than 400mm, C side is not less than 1000mm).
• Power supply voltage allowable fluctuation range is 10%, frequency is 50 +/- 0.5Hz, protective ground resistance is less than 4Ω.
• The water quality of the water supply must meet the second-level water standard of the National Analytical Laboratory, and the solid impurity content is less than 1mg/L.
The working environment temperature should be 5~ 30 ℃, humidity ≤ 85% R.H.
• When the equipment is running, pay attention to monitoring over-temperature, over-current and other protection devices, and deal with fault alarms in a timely manner.
• Use the whole machine freight method during transportation to avoid violent vibration.
