Overview
HUDA QD-E708-150K40-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 humidity cabinet 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
2. Self-developed multi-channel multi-stage throttling system to ensure adjustable flow, uniform temperature field, and minimal fluctuations
3, the application of broadband compression equilibrating temperature control system, through PID adaptive algorithm to achieve rapid temperature convergence control
4. Configure the man-machine management interface and RS485 communication to support remote visual control and graphical fault diagnosis
Principle
The equipment adaptively adjusts the refrigeration output according to the working conditions through a multi-channel mechanical compression refrigeration system and a multi-stage throttling system; uses a temperature adjustment chamber, a static pressure chamber, and a centrifugal fan blade forced air duct system to ensure that hot and cold are fully exchanged and evenly sent to the studio; uses a PID adaptive algorithm to correct the control parameters in real time to achieve rapid temperature convergence and stable control.
Applications
Electronics, automotive parts, materials
