GAS ENRICHMENT DEVICE AND AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a gas enrichment device and an air conditioner using the same that can change the driving rate of a differential pressure generating means according to the conditions influencing a rise in temperature of the differential pressure generating means with longevity and high reliability. SOLUTION: The gas enrichment device 1 is provided with at least a gas enrichment means (oxygen enrichment unit 2), the differential pressure generating means (pressure reduction pump 3) generating differential pressure in the gas enrichment means, and a driving time detecting means detecting the driving time of the differential pressure generating means and runs the differential pressure generating means based on the driving time continuously. The system helps to vary the driving rate of the differential pressure generating means according to the conditions influencing the rise in temperature of the differential pressure generating means and realize the gas enrichment device with the longevity and the high reliability.
