Programmed temperature control of a thermal system |
摘要 |
The invention resides in the temperature control of the oven of a gas chromatograph. A variable speed fan circulates air within the oven. Vents in the oven wall open automatically in response to pressure imbalances between the ambient atmosphere and the oven interior. Temperature is controlled by regulated exchanges of ambient and oven air produced by variations in fan speed.
