In case of air to air chamber the heated air and cooled air are used

3 Zone: Sample is placed in the test chamber at higher temperature than test temperature, in high-temperature chamber and low-temperature chamber. Rather than only hot and cold temperature the specimen flows between hot, ambient, and cold zones. When converted into high-temperature test, cold chamber and ambient chamber door is closed, hot chamberdoors are opened, and test chamber works. When it comes to low temperaturetest, cold chamber door open, and low-temperature chamber works.

When it comes to ambient chamber temperature test, ambient chamber door open, and ambient-temperature chamber works.
