Overview
HUDA QD-E708-150K60-X5 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, with beautiful appearance, easy operation, safety, high temperature and humidity control accuracy, suitable for rapid temperature change test, constant temperature and humidity test and alternating humidity cabinet test.
Features
1. Adopt multi-channel environmentally friendly and energy-saving mechanical compression refrigeration system, energy consumption only accounts for 80% of congeneric products, and equipped with frequency conversion technology to reduce noise and vibration.
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control to ensure uniform temperature field and small fluctuations.
3, the application of broadband compression equilibrating temperature control system, combined with PID adaptive algorithm to achieve rapid temperature convergence and stability control.
4. Support remote visual control, remote monitoring through RS485 communication, and a graphical interface to provide trouble prompts and solutions.
Principle
The equipment automatically controls the refrigeration output and flow adjustment according to the working conditions through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system to achieve temperature changes. The forced air duct system using a temperature harmonizing chamber, a static pressure chamber and a centrifugal fan blade ensures that the hot and cold are fully exchanged and the air is evenly supplied to the studio. Combined with the PID adaptive algorithm, the temperature is quickly controlled. The control system automatically adjusts the operation of the refrigerator through a programmable logic controller to ensure accurate control of temperature and humidity.
Applications

Steps
1. Ensure that the ground of the installation site is flat, well ventilated, free of flammable and explosive gases, and reserve maintenance space.
2. Connect the power supply, using AC380V three-phase four-wire power supply, and the protective ground wire grounding resistance is less than 4Ω.
3. Set the temperature and humidity parameters through the touch screen controller, and select the program or set operating mode.
4. Start the equipment, and the system automatically controls the refrigeration, heating, and humidification processes, monitoring the operating status.
5. After the operation, check the status of the equipment and perform cleaning and maintenance if necessary.
Notice
• The installation site needs to be flat, well ventilated, and does not contain flammable, explosive and corrosive gases.
• Power supply voltage allowable fluctuation range of 10%, frequency allowable fluctuation range of 50 +/- 0.5Hz.
• The water quality of the water supply is required to meet the secondary water use standard of the National Analytical Laboratory.
• Pay attention to the status of over-temperature, over-current and other protection devices when the equipment is running.
• Make sure the whole machine is fixed during transportation to avoid collision damage.
