Overview
HUDA QD-E708-150K60-X10 rapid temperature change test chamber is a professional equipment used to determine the adaptability of electronic products, automotive parts, materials, etc. under the conditions of high humidity, low humidity, constant heat and humidity, high and low temperature rapid alternating cycle, surface condensation heat and humidity. The testing machine adopts a reasonable structure and a stable and reliable Control mode, which has the characteristics of beautiful appearance, simple operation, safety and reliability, and high temperature and humidity control accuracy. It is suitable for rapid temperature change test, constant temperature and humidity test and alternating humidity cabinet test.
Features
1, using multi-channel environmental protection and energy-saving mechanical compression refrigeration system, energy consumption only accounts for 80% of congeneric products, through frequency conversion technology and sound absorption design to achieve energy saving and noise reduction.
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control to ensure uniform and stable temperature field.
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. Configure the human-machine management interface and RS485 communication, support remote visual control, and provide graphical fault prompts and solution guidance.
Principle
The equipment adaptively selects the enabling path according to the working conditions through the multi-channel mechanical compression refrigeration system and the two-stage multi-channel main bypass system, and uses frequency conversion technology to adjust the refrigeration output. The flow rate is adjustable through the capillary tubing throttling system. Combined with the forced air duct system of the temperature adjustment chamber, the static pressure chamber and the centrifugal fan blade, the hot and cold are fully exchanged and evenly transferred to the studio. The PID adaptive algorithm is used to continuously modify the control parameters to achieve rapid convergence and stable control of temperature.

Steps
1. Ensure that the ground of the installation site is flat, well ventilated, and free of flammable and explosive corrosive gases and dust.
2. Connect the power supply, use AC380V three-phase four-wire system + protective grounding, and confirm that the voltage and frequency are within the allowable range.
3. Set the temperature and humidity parameters through the touch screen controller, and you can choose the program mode or the fixed value mode to operate.
4. Start the equipment and monitor the actual temperature and humidity display to ensure normal operation.
5. After completing the test, shut down the equipment according to the program and perform maintenance and cleaning if necessary.
Notice
The installation site should have a load-bearing capacity of not less than 600kg/m ², and maintenance space should be reserved around it (not less than 400mm on both sides, and not less than 1000mm on the front).
• Power supply must comply with TN-S or TT mode, and the grounding resistance of the protective ground wire 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 kept at 5~ 30 ℃, humidity ≤ 85% R.H.
• Pay attention to monitoring the status of over-temperature, over-current, and lack of protection devices when the equipment is running.
• The whole machine needs to be shipped during transportation to avoid violent vibration.
