Refrigeration System of the Test Chamber
The refrigeration system plays a critical role in the performance and consistency of the test chamber. Its stability directly impacts the accuracy and reliability of testing outcomes.
- Advanced Defrost Technology: Qualitest has developed a hot gas defrosting system that uses high-temperature, high-pressure refrigerant vapor to eliminate frost buildup on the evaporator. This prevents frost formation while significantly reducing energy consumption.
- High-Quality Components: The refrigeration unit features components from globally recognized brands. Qualitest has introduced EPV and XUP series energy-efficient quick-opening solenoid valves. These components are designed for durability, with a service life exceeding 15 years. Development is also underway on the Danfoss AKV series electronic expansion valves, which offer improved efficiency, reduced noise, and better energy savings.
- Optimized System Design: The system uses Variable Refrigerant Flow (VRF) technology, based on PID-controlled cold-end output, to deliver efficient low-temperature operation—cutting energy use by up to 30% in cold environments.
- Modular Configuration: The refrigeration system is built with a modular approach, ensuring high cooling efficiency, fewer failure points, simplified maintenance, and reduced upkeep costs.
This robust design ensures consistent operation while minimizing energy use and long-term maintenance requirements.
