Utilizes EZNET remote network technology for real-time monitoring and control. Users can access live data and control settings via PC or mobile devices, enhancing testing flexibility.
Note: Control system features may vary by model. Please consult the Environmental Test Chamber Manual and follow all safety guidelines before operation.
Refrigeration System of the Climatic Test Chamber
The refrigeration system is a critical component of the test chamber, directly impacting the accuracy and consistency of test results. Qualitest integrates advanced technologies to ensure stability, efficiency, and long-term reliability.
- Hot Gas Defrost Technology:
Qualitest has developed a refrigerant hot gas defrosting method that injects high-temperature, high-pressure refrigerant vapor into the chamber’s heat exchanger to eliminate frost on the evaporator. This process improves system performance while significantly reducing energy consumption. - Premium Refrigeration Components:
The system features components from leading global brands. Qualitest utilizes EPV and XUP series energy-saving solenoid valves with an extended service life of over 15 years. Development is also underway for a next-generation throttling system using Danfoss AKV electronic expansion valves for improved efficiency, lower noise, and reduced energy use. - Energy-Efficient Design:
The system layout is optimized using VRF (Variable Refrigerant Flow) technology based on PID cold-end output control. This allows for efficient low-temperature operation and can cut energy consumption by up to 30% in cold testing conditions. - Modular Construction:
The refrigeration system features a modular design that minimizes welding points, enhances cooling efficiency, and improves reliability. It also simplifies maintenance, reduces downtime, and keeps service costs low.
