PURPOSE:To perform a self-control of an air current without the exertion of an external power, by a method wherein, an air outlet which forms an annular air outlet by placing a circular cone core at a center of a circular opening, a blow- off direction is caused to vary through movement of said core as a result of a change in a shape of a shape memory alloy. CONSTITUTION:A radial flow type air outlet, installed to a ceiling surface 5, is constituted such that an outer cone 6, which widens toward the end, is connected to a duct 7 and an inner cone 8 is coupled to the inside of the outer cone 6. A circular cone core 1 is concentrically positioned at a center of a circular opening in the inner cone 8, to form an annular air outlet 2. In which a case, a shaft 10 extending along a center axis is attached to the circular cone core 1 at a side opposite to that of the inside of a room, and a shape memory alloy 3 is attached to a position facing the indoor side so that the one end thereof is connected to the circular cone core 1 and the other end is joined to a fixing member 4. This causes varying, in a direction along the shaft, of the shape memory alloy 3 due to a temperature change, and allows to vary with said change in a blow-off direction of an air current flowing from the annular air outlet 2. |
