Common Faults and Solutions in Constant Temperature and Humidity Chambers (Part 1)
Constant Temperature and Humidity Test Chamber (CTHC) is a cornerstone of environmental testing, providing controlled conditions to evaluate product resilience. However, these chambers can encounter various operational issues. This two-part article will address common faults and their solutions, ensuring that technicians and operators can maintain optimal performance and safety.
1. Unstable Temperature and Humidity Control
Solution: Verify the calibration of the chamber's sensors. If the sensors are drifting, recalibrate or replace them. Check the PID controller settings and adjust the proportional, integral, and derivative gains for optimal control.
2. Excessive Noise During Operation
Solution: Inspect the fan for debris or misalignment. If the compressor is the source, ensure it is properly lubricated and not overworked. Replace any worn components to restore quiet operation.
3. Internal Water Leakage
Solution: Trace the source of the leak, checking the water tank, pipes, and chamber seals. Repair or replace damaged components and ensure that all connections are tight and sealed.
4. Failure to Start or Stop
Solution: Check the power supply and circuit breakers for any interruptions. Inspect the control panel for error codes that can indicate specific issues. Reset the system and check for any loose wiring or connections.
5. Abnormal Display
Solution: Ensure that the display is properly connected and that there is no damage to the wiring. Reset the control system and, if necessary, update the firmware or software to the latest version.
