Refrigeration System of Thermal Shock Test Chambers
The refrigeration system is a critical component of the thermal shock test chamber, directly impacting the accuracy and consistency of test results. Qualitest integrates advanced technologies to ensure high performance and energy efficiency.
- Innovative Defrost Technology: Qualitest's hot air refrigerant defrosting system injects high-temperature, high-pressure refrigerant vapor into the heat exchanger to eliminate frost buildup on the evaporator. This prevents freezing and significantly reduces energy consumption.
- High-Quality Components: The system features globally recognized refrigeration units and collaborates with Japan and the U.S to develop energy-efficient EPV and XUP series quick-opening solenoid valves. It also incorporates the new Danfoss AKV series electronic expansion valve system for improved efficiency.
- Energy Optimization: The refrigeration layout uses VRF (Variable Refrigerant Flow) technology, based on PID-controlled cold-end output, to enable low-temperature operation with up to 30% energy savings.
- Modular Design: The system is built with a modular approach, reducing the number of welding joints and enhancing overall reliability. This results in higher efficiency, fewer breakdowns, easier maintenance, and lower repair costs.
Qualitest's refrigeration system is engineered for long-term performance and dependable operation in demanding testing environments.
