Overview
HUDA QD-E708-512K60-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 equipment adopts reasonable structure and 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 cabinet humidity test.
Features
1. Adopt multi-channel environmental protection and energy-saving mechanical compression refrigeration system, energy consumption only accounts for 80% of congeneric products, equipped with frequency conversion technology and sound absorption and silencing design to achieve low noise operation.
2. Equipped with self-developed multi-channel and multi-stage throttling system, the capillary tubing throttling is automatically adjusted through the intelligent control system to ensure adjustable flow and uniform temperature field.
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, connect to a remote computer through the RS485 communication interface, and provide automatic trouble prompts and solutions through a graphical interface.
Principle
The equipment automatically adjusts the refrigeration output and flow 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. The control system uses a PID adaptive algorithm to continuously modify the control parameters to ensure rapid temperature convergence and Stability.
Applications
