Abstract
An air conditioning apparatus includes an air grille having a right side grille, a left side grille and a sub grille disposed between the right side and left side grilles. At the start of the heating operation, the right side and left side grilles and the sub grille are at a downward air flow position at which heating air flows downwardly. A prescribed time after the start of the heting operation, or when the difference between the tempeature of the wall on which the apparatus is installed and a desired room temperature has come into a prescribed range, the right side and left side grilles are rotated to a diagonally-downwardly air flow position at which a portion of the heating air flows diagonally-downwardly while the sub grille is maintained at the downward air flow position.
