If the temperature exceeds the set value during testing in a constant temperature and humidity test chamber, how should we resolve it? Are there any emergency response measures?

It is crucial to operate a high and low temperature test chamber correctly.

High-low temperature test chambers are precision instruments that must be operated strictly by trained personnel following standard procedures and subjected to regular preventive maintenance. Any operational error or neglected upkeep can trigger a variety of faults, delaying test schedules. The equipment integrates refrigeration, heating, humidification, electrical control and other subsystems. Effective troubleshooting therefore requires a holistic “whole-machine mindset” to pinpoint and solve problems quickly.

From the outside, a high and low temperature test chamber may appear to be just a large box. However, its internal structure is not as simple as it seems.

Thermal vacuum testing is a type of test that verifies the performance and functionality of spacecraft and its components under vacuum and specific temperature conditions.
