ABSTRACT:
A method of liquefying Freon gas using a vessel having an inner and an outer tank, and a jacket around the inner tank which comprises the steps of operating a vacuum pump, opening a solenoid valve to evacuate the air in the space formed between the outer periphery of the inner tank and said jacket to form a vacuum, then supplying Freon gas from a bomb into the inner tank, and cooling the Freon gas in the inner tank through a heat exchange medium such as helium in said space while supplying a cooling medium to a second space between said jacket outer wall and said outer tank inner wall space to thereby liquefy the Freon gas.
