In an air conditioning method and system for supplying conditioned air to an enclosed space, such as a room or rooms in a building, air is withdrawn from the room at separate positions located adjacent the floor and ceiling in order to advantageously utilize the effects of a convection within the room. Depending upon the season or the demand, air withdrawn from one of these positions is discharged into the atmosphere, while air withdrawn from the other of the positions is supplied, as return air, to an air conditioning unit, at which it is heated or cooled. A predetermined amount of outside air is also supplied to the air conditioning unit with the return air and the combined air flow, after treatment in the conditioning unit, is supplied to the enclosed air space or room.
