ている。2. Description of the Related Art As a conventional ceiling cooling and heating system, a system shown in FIG. 5 is well known. In this ceiling cooling and heating system, the cooling and heating air that has been heat-exchanged by the heat exchanger 10 arranged behind the ceiling is passed through the air conditioning flow path 3 formed by arranging the flat plate 2 on the back side of the ceiling material 1, The room 14 is cooled and heated by allowing it to cool or dissipate heat. In this cooling / heating system, as shown by the arrow in the figure, the cooling / heating air is formed so as to flow from the right to the left in the air-conditioning flow path 3.

を流すことができる。Further, as shown in FIG. 6, the air-conditioning flow path 3 between the ceiling material 1 and the flat plate 2 with respect to the ceiling surface having a rectangular shape in plan view.
It is also practiced to form a divided air-conditioning flow path 3 so that the heating and cooling air flows back and forth on the ceiling surface in the figure by partitioning the gap that becomes. According to such an air conditioning flow path 3, it is possible to flow the cooling and heating air more uniformly over the entire ceiling surface.

Because the conditioned air is not blown directly to the 14, warm or cold air does not hit the body directly, and mild air conditioning is performed. Further, since the devices are not present in the room 14, it is preferable in that the room can be cooled and heated without being aware of the presence of the air conditioner and the indoor space can be refreshed.

が発生しやすいのである。However, in the above-mentioned conventional example, the air flowing through the air-conditioning flow path 3 becomes closer to the temperature of the room 14 toward the downstream side, and is radiated from the ceiling material 1 to the room. The amount of heat will decrease. For this reason, the heat radiation environment into the room becomes non-uniform, and unevenness in heating and cooling is likely to occur in the room 14.

In the ceiling air-conditioning system, in which the air-conditioning flow path 3 through which cooling and heating air flows is formed in the gap, the ceiling material 1 is reduced from the inlet 4 to the outlet 5 of the air-conditioning flow path 3 so as to reduce the thermal resistance. It is characterized by being formed.

やすくなっている。In such a ceiling cooling and heating system, the temperature of the cooling and heating air gradually approaches the temperature of the room 14 while the cooling and heating air flows through the air conditioning passage 3 from the inlet 4 to the outlet 5. However, since the thermal resistance of the ceiling material 1 decreases from the inlet 4 to the outlet 5 of the air conditioning flow path 3, heat is likely to be transferred between the cooling and heating air and the surface of the ceiling material 1. Therefore, as the air-conditioning flow path 3 goes from the inlet 4 to the outlet 5, the surface temperature of the ceiling material 1 is greatly affected by the cooling and heating air, and the temperature of the surface of the ceiling material 1 tends to be constant.
