Abstract:
An air conditioner comprising:an outdoor unit having an outdoor heat exchanger for performing heat exchange between a heat-exchanging medium and exterior air; an indoor unit having an indoor heat exchanger for performing heat exchange between room air and the heat-exchanging medium; and an oxygen-enriched air supplying device including an air compressor for providing a compressed air, an oxygen-enriched air separator for separating the compressed air into oxygen-enriched air and nitrogen-enriched air; and a supply tube for supplying the oxygen-enriched air provided from the oxygen-enriched air separator to the indoor unit, wherein the oxygen enriched air separator includes: a main body; an oxygen-enriched air outlet port exhausting the oxygen-enriched air through the supply tube; a nitrogen-enriched air outlet port for exhausting the nitrogen-enriched air to the atmosphere; separation membranes for separating the compressed air into an oxygen enriched air and a nitrogen-enriched air, wherein an inside of the main body is divided into a first space communicated with the nitrogen-enriched air outlet port and a second space communicated with the oxygen-enriched air outlet port; and a pressure maintenance unit for maintaining a pressure difference between the first and the second space greater than a predetermined level.
