Facility Description

The thermal vacuum chambers are used for the purpose of simulating a satellite circling in an orbit, in order to test a satellite's operating performance in the space environment, where near vacuum and great temperature fluctuation conditions are present.

When a test is conducted, satellite is securely placed in the chamber, where a pump is used to draw out all the air, while liquid nitrogen, gas nitrogen and a heater are used for temperature control. Tests carried out generally include thermal vacuum, thermal circulation and thermal balance, to check whether the satellite can operate normally under a vacuum environment and whether the thermal control analysis performed during the design phase was accurate.
