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. Adopt multi-channel environmentally friendly and energy-saving mechanical compression refrigeration system, use environmentally friendly materials, two-stage multi-channel main bypass system adaptive selection and activation, energy consumption only accounts for 80% of congeneric products, frequency conversion technology is used to reduce vibration and noise.
2. Self-developed multi-channel multi-stage throttling system, automatically adjusting capillary tubing throttling through intelligent control system to ensure adjustable flow, uniform temperature field and small fluctuation.
3, the application of broadband compression equilibrate temperature control system, through the PID adaptive algorithm to achieve rapid temperature control, the use of temperature chamber and forced air duct system to ensure temperature uniformity.
4. Realize remote visual control, configure human-machine management interface and RS485 communication, support graphical interface, automatic fault prompt, and remote monitoring.
Principle
The equipment automatically adjusts the refrigeration output and flow rate according to the working conditions through a multi-channel mechanical compression refrigeration system and a self-developed multi-stage throttling system to achieve rapid temperature changes. The application of a broadband compression equilibrate temperature control system, combined with a forced air duct system of a temperature reconciliation chamber, a static pressure chamber and a centrifugal fan blade, ensures that hot and cold are fully exchanged and evenly supplied to the studio. The PID adaptive algorithm is used to quickly converge temperature control to reduce overshoot and improve Stability.
