Abstract

PURPOSE:A new gas is cooled so that the weight per the unit volume becomes heavier than that of the gas in the chamber and it is quietely sent into the chamber to displace the old gas in the chamber efficiently. CONSTITUTION:A new gas such as nitrogen is cooled so that the density becomes higher than that of the gas in the chamber and sent quietely from pipe 3 through inlets 2. The new gas sent into the chamber forms the layer 6 along the bottom surface 1A because of its large difference in density and gradually grows the thickness. At the same time, fan 5 is driven to expel out the old gas by an amount equal to that of the gas sent into.
