The oxygen-enriched gas in the oxygen-enriched membrane assembly flows out from the connection port 141 of the oxygen-enriched membrane assembly, flows into the vacuum pump 15 through the connection pipeline 16 from the gas inlet 151 of the vacuum pump 15, and is discharged from the gas outlet 152 of the vacuum pump 15. Oxygen-enriched gas discharged from a gas outlet 152 of the vacuum pump 15 enters the oxygen-enriched conveying pipeline 17 and is conveyed to the air-conditioning indoor unit, and then the air-conditioning indoor unit conveys the oxygen-enriched gas into the indoor space so as to improve the oxygen content of indoor air and provide a comfortable indoor environment for users. The nitrogen-rich gas in the oxygen-enriched device 1 flows through the vacuum pump 15, takes away heat generated by the operation of the vacuum pump 15, and is discharged to the outside through the exhaust port 18 provided on the housing 11.
