Abstract
A storage facility includes N accommodating sections, where N is a positive integer, M main pipes through which an inert gas flows, where M is a positive integer of 2≤M<N, M flow control devices, M branch pipe groups, and a plurality of switching valves. Each branch pipe group includes N branch pipes, and the switching valves are respectively provided on the branch pipes included in at least (M−1) of the branch pipe groups. Each flow control device is configured to control the flow rate of the inert gas flowing through the main pipe to which this flow control device is connected, based on a flow-through pipe count, which is the number of the branch pipes for which the flow of the inert gas is not blocked by the switching valve, out of the N branch pipes of the branch pipe group that corresponds to this main pipe.
