Abstract:
Disclosed is an oxygen enrichment that can follow changes in adsorption performance in response to changes in the temperature of the usage environment and can reduce power consumption. The oxygen enrichment device has a purge step control means that controls a purge step time to increase/decrease the length of a purge step so as to maximize the oxygen concentration by changing opening/closing timing of a flow-channel switching means while the oxygen enrichment device is running.
