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 low noise operation is achieved through frequency conversion technology and sound absorption and silencing design.
2. Equipped with self-developed multi-channel and multi-stage throttling system, the capillary tubing throttling is automatically adjusted through intelligent control to ensure uniform temperature field and minimal fluctuation.
3, the application of broadband compression equilibrating temperature control system and fast convergence PID adaptive algorithm to achieve rapid control and uniform distribution of temperature.
4. Support remote visual control, remote monitoring through human-machine interface and RS485 communication, with graphical fault prompts and solution guidance.
Principle
The test chamber adaptively adjusts the cooling output according to the working conditions through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system to achieve rapid temperature changes. 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 uses PID adaptive algorithm to continuously correct the temperature control to ensure fast convergence and Stability. The humidification system uses electric boiler humidification and Compressor dehumidification, and the required humidity is achieved through P.I.D. control.

Steps
1. Ensure that the ground of the installation site is flat, well ventilated, free of flammable and explosive corrosive gases, and reserve appropriate maintenance space.
2. Connect the power supply, use AC380V three-phase four-wire system + protective grounding, and check the voltage and frequency fluctuation range.
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 actual value of temperature and humidity, and execute the program to perform operations such as skipping and holding.
5. After use, shut down according to the program and perform equipment cleaning and maintenance if necessary.
Notice
• The installation site requires a ground load-bearing capacity of not less than 600kg/m ², and the surrounding maintenance space A is not less than 400mm, B is not less than 400mm, and C is not less than 1000mm.
• Power supply voltage allowable fluctuation range of 10%, frequency allowable fluctuation range of 50 +/- 0.5Hz, protective ground wire grounding 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, to avoid strong electromagnetic radiation sources.
• In case of failure during the operation of the equipment, the system will automatically prompt and guide the troubleshooting, and do not disassemble it by yourself.
• The whole machine needs to be shipped during transportation to ensure the stability of the equipment and prevent damage.
