PURPOSE: A method for supplying the air through an indoor unit is provided to settle inconvenience in construction work and economic problems by complexly supplying cool air and the air simultaneously to the indoor through the indoor unit, not forming a discharge port for supplying air to a ceiling wall. CONSTITUTION: In a method for supplying the air through an indoor unit, a refrigerant branch tube(11) branched in a refrigerant pipe(1) through a hole is connected with a refrigerant coil(21) installed inside, and heat is exchanged with the exterior air. A hole is formed on the other side of the indoor unit discharging cool air by a blowing fan(22) and then a branch tube(31) for supplying the air branched from a duct tube(3) for supplying the air is penetrated and is protruded to a space part(4) formed inside the indoor unit. Accordingly, the air supplied from the branch tube for supplying the air is discharged together with cool air, from a discharge port of the indoor unit when the indoor unit is operated.
