TEMPERATURE RECOVERY AT –70°C

  • Temperature rise during 30s door opening
  • Temperature rise during 60s door opening
  • Temperature rise during 120s door opening
  • Recovery time to return to setpoint after each opening
  • Performance comparison between system cooling loops (SYS1/SYS2)

  • Temperature measurements from distributed probe locations
  • Maximum, minimum, and average chamber temperatures
  • Temperature deviation across the chamber
  • Steady-state stability assessment

 

Airflow circulation

The test evaluates whether airflow is delivered evenly throughout the chamber and identifies any areas that may experience limited airflow, recirculation zones, or temperature variations that could impact overall system performance.
