効果が低いという課題があった。Problems to be Solved by the Invention In such a conventional configuration, the surface temperature of the cold radiant panel is determined by the air temperature near the panel surface and the relative humidity, for example, 70.

Even if the temperature near the surface of the cold radiant panel is the same, the relative humidity is 7.
When the temperature exceeds 0, dew condensation occurs on the surface of the cold radiant panel, and conversely, when the relative temperature falls below 70%, the surface temperature of the cold radiant panel can be lowered without condensation, but the set relative temperature is kept constant. Therefore, there was a problem that the surface temperature of the cooling radiant panel could not be lowered below the dew point temperature of the set relative humidity, resulting in a low cooling effect.
