Abstract
An environmental test chamber, and method of testing a response of a unit-under-test to treated air, includes a housing having an enclosing wall defining a test bay with an access opening in the wall providing access to the test bay and a closure selectively covering the opening. An airflow plenum supplies treated air to the test bay. An air treatment system treating air flowing through the plenum. A control operates the air treatment system to flow treated air through the plenum in two selective modes. The air treatment system flows treated air in a first flow direction through the test bay in one of the modes and flows air in a second flow direction through the test bay in a second of the modes. The first and second flow directions are different from each other.
