FITTING

To provide a fitting that can reduce the heat flow in and out of a window to thereby reduce the heating and cooling load.SOLUTION: The fitting includes an outer glass 1, an inner glass 2, a flow adjusting body 3, an outdoor ventilation section 4 that leads from an outdoor space to an intermediate layer 6 between the outer glass 1 and the inner glass 2, and an indoor ventilation section 5 that leads from the intermediate layer 6 to an indoor space. The flow adjusting body 3, which is located in the intermediate layer 6, directs an air from the outdoor ventilation section 4 in the downward and the left and right directions. The air flows in one direction along the inner surface of the outer glass 1 while in communication with the outdoor, folds back at the edge of the intermediate layer 6, and flows in the other direction along the outer surface of the inner glass 2 while in communication with the indoor, thereby recovering heat that escapes from the indoor to the outdoor or discarding heat that comes into the indoor from the outdoor to the outdoor.SELECTED DRAWING: Figure 1 【課題】 窓からの熱の出入りを減らし、冷暖房負荷を抑えることのできる建具の提供。【解決手段】 外側ガラス１と内側ガラス２と整流体３とを備え、室外空間から外側ガラス１と内側ガラス２との間の中間層６に通じる室外側通気部４と、中間層６から室内空間に通じる室内側通気部５を有し、整流体３は、中間層６に設けてあり、室外側通気部４からの空気を下方及び左右方向に導くものであり、室外と連通して外側ガラス１の内側面に沿って一方向に空気が流れ、中間層６の端部で折り返し、室内と連通して内側ガラス２の外側面に沿って他方向に空気が流れることで、室内から室外に逃げる熱を回収するか、室外から室内に入ってくる熱を室外に捨てる。【選択図】 図１
