Abstract
An air conditioner includes an oxygen-enriched air separator for separating exterior air into oxygen-enriched air and nitrogen-enriched air and an oxygen-enriched air supplier for supplying the separated oxygen-enriched air to an indoor unit. The oxygen-enriched air separator has a main body, an oxygen-enriched air outlet port connected to the indoor unit through a supply tube, a nitrogen-enriched air outlet port for exhausting the nitrogen enriched air and a pressure maintenance unit for maintaining a pressure difference between a first space communicated with the nitrogen-enriched air outlet port and a second space communicated with the oxygen-enriched air outlet port over a predetermined level.
