An internal air adjustment device supplies low-oxygen-concentration air to a storage, and maintains the oxygen concentration of internal air in a target oxygen concentration range that is lower than a reference concentration. The internal air adjustment device performs an oxygen-concentration restoration operation. The oxygen-concentration restoration operation is an operation of increasing the oxygen concentration of the internal air to the reference concentration from the target oxygen concentration range. In the oxygen-concentration restoration operation, a controller of the internal air adjustment device regulates the flow rate of external air that is supplied into the interior of the storage.
