METHOD FOR FILLING LIQUID AIR

摘要

PROBLEM TO BE SOLVED: To provide a method for filling a cooling mechanism with liquid air while sustaining the concentration thereof. SOLUTION: Liquid nitrogen and liquid oxygen are mixed in a cooling mechanism to produce liquid air of specified component. The cooling mechanism comprises a reservoir tank 1 and an weight meter 6 for measuring the weight of liquid in the reservoir tank. Liquid nitrogen and liquid oxygen are fed to the reservoir tank 1 and mixed to produce liquid air of specified component based on the measurements of the weight meter 6. Preferably, the cooling mechanism is filled with liquid nitrogen and cooled before liquid nitrogen and liquid oxygen are mixed.
