PURPOSE: An oxygen feeder of an air conditioner is provided to keep indoor air pleasant by inducing air to a suction pipe and discharging only oxygen to an indoor space through an evaporator. CONSTITUTION: In using a first adsorption column(32), air is absorbed into a suction pipe(11) by a suction motor(10). After that, the suction pipe is connected to a second connecting pipe(31) and an exhaust pipe(51) is joined with a first connecting pipe(21) by operating a change valve(20). A first non-return valve(23) is closed and a second one(33) is opened. The suction air is introduced into the second connecting pipe through the change valve and passes the first adsorption column. The rest air except oxygen is adsorbed by operating the first adsorption column and the oxygen is supplied to a feed pipe(40) through the second non-return valve. Finally, the air is introduced into an air conditioner, cooled by an evaporator(64) and discharged to an indoor space to cool the space pleasantly.
