なわず、且つエネルギー面からも有利である。This change in skin temperature is most effective for stimulating the cold feeling of the person (8) in the room. That is, as shown in FIG. 3, while the rate of change in skin temperature is decreasing from the upper limit set value S H to the lower limit set value S L (step n6), it is effective for stimulating a cold sensation. When the rate of change reaches the point A of the lower limit set value S L (step n7), it is determined that a sufficient cooling effect is obtained, and the operation of the radiation panel (1) is stopped (step n10). When the operation of the radiant panel (1) is stopped, the surface temperature of the radiant panel (1) rises, but during the rise, the person (8) in the room is not sensitive to cooling and the cooling effect continues for a while. When the warmth gradually rises and reaches point B in FIG. 3 (step n8), the operation of the radiation panel (1) is started again (step n9). As described above, the intermittent operation of the radiation panel (1) depending on the rate of change of the skin temperature does not impair the cooling effect and is advantageous from the energy viewpoint.
