Control System Of The Test Chambers
The control system of the AGREE Test Chamber is built with advanced software and hardware to ensure stable operation under preset conditions. It delivers accurate, reliable test data while enabling precise control and monitoring of experimental environments.
- Controller: Features a high-performance control system that can be integrated with Siemens controllers, equipped with RS232, RS485, and Ethernet communication ports.
- Programmable Control: Allows setup of custom test programs such as heating, cooling, and constant temperature cycles. Multiple programs can be executed, and start times can be scheduled in advance.
- Multi-Language Support: Available in English and others.
- Remote Monitoring: Network-based remote access enables real-time monitoring and control from both PC and mobile devices for enhanced convenience.

Refrigeration System Of The Test Chamber
The refrigeration system is a critical component of the test chamber, as its stability directly affects the accuracy and reliability of results.
- Hot Gas Defrost Technology: Uses high-temperature, high-pressure refrigerant steam to remove frost from the evaporator. This prevents ice buildup and significantly reduces energy consumption.
- High-Quality Components: Built with internationally recognized refrigeration brands. Advanced energy-saving solenoid valves (EPV and XUP series) were developed with an all-weather service life of over 15 years. A new Danfoss AKV electronic expansion valve system is also being introduced, offering improved efficiency, lower energy use, and reduced noise.
- Optimized Refrigerant Flow: Incorporates VRF (variable refrigerant flow) technology based on the PID cold-end output principle. This design enables low-temperature, energy-saving operation and can cut energy consumption by up to 30% under low-temperature conditions.
- Modular Design: Features a streamlined structure with fewer welding points, low failure rates, high cooling efficiency, easy maintenance, and reduced service costs.
