Abstract

A gas enrichment device having a gas enrichment unit and a differential pressure generating device connected to each other and capable of discharging wet air passed through the gas enrichment unit and preventing the air from being frozen, comprising at least a gas enrichment means (1), a differential pressure generating means (2) allowing a differential pressure to be generated by the gas enrichment means (1), a gas feeding passage (3) for feeding second gas gas-enriched by allowing first gas to be passed through the gas enrichment means (1), and a flow passage opening/closing means (4) for feeding third gas having a smaller relative humidity over the second gas to the gas feeding passage (3).
