低下させることが必要になる。Generally, in order to obtain an air conditioning effect, for example, a convection method is used in which cooled air is convected during cooling. On the other hand, there has been proposed a radiant air conditioner that directly cools a person, a wall surface, or the like by cooling an air-conditioning target area by radiation. However, heat transfer due to radiation is small, and in order to obtain an effective cooling capacity, it is necessary to widen the area of the radiation plate 2 or further lower the cooling surface temperature by the radiation plate 2.
