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.
Claims12
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.
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 connected to the indoor unit through the supply tube;
- a nitrogen-enriched air outlet port for exhausting the nitrogen-enriched air to the outside;
- and
- 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 heating means for heating the separation membranes up to a predetermined temperature so as to improve the oxygen selective permeability of the separation membranes.
