Overview
HUDA QD-E708-150K60-X15 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, alternating humidity cabinet test.
Features
1, using multi-channel, environmental protection and energy saving (low noise) mechanical compression refrigeration system, energy consumption only accounts for 80% of congeneric products, through frequency conversion technology implementation of energy saving effect
2. The self-developed multi-channel and multi-stage throttling system ensures that the flow rate is adjustable, the temperature field changes uniformly, and the temperature fluctuation is minimal
3, the application of broadband compression equilibrating temperature control system, through the fast convergence of PID adaptive algorithm to achieve rapid temperature control
4. Realize remote visual control, configure human-machine management interface and RS485 communication interface, and support graphical fault prompts and solutions
Principle
The test chamber adopts a multi-channel mechanical compression refrigeration system and a multi-stage throttling system, and automatically adjusts the refrigeration output according to the working conditions through an intelligent control system. 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 evenly transmitted to the studio. Fast temperature control is realized through a fast convergent PID adaptive algorithm to ensure temperature uniformity and Stability.
