PROBLEM TO BE SOLVED: To provide a gas enriching device, a differential pressure generating device, and an air conditioner using these devices capable of preventing condensed water from being frozen during transportation even when the outside temperature is low by minimizing the occurrence of the condensed water during the transportation of gas enriched gas of the gas enriching device. SOLUTION: The gas enriching device comprises at least a gas enriching means, a differential pressure generating means making the gas enriching means to generate differential pressure, a gas feed passage feeding gas enriched second gas by allowing first gas to pass the gas enriching means, and a flow passage open/close means for supplying third gas with a relative humidity lower than that of the second gas to the gas feed passage.
