スが大きく不経済である。2. Description of the Related Art In a conventional ceiling cooling system, a cooling mechanism has been operated by using a heat source independent of a general air conditioning mechanism. In addition, since the ceiling type cooling system generates latent heat during long-term operation, cooling efficiency is reduced. In this case, when removing this latent heat, it was necessary to avoid dew condensation on the ceiling, so a special dehumidifier was required. Also, since the operating temperature range of the heat source is different, two types were required, one for the ceiling radiation cooling and one for the dehumidifier. Such a cooling system occupies a space and is uneconomical with a large loss in terms of thermal efficiency and thermal energy.
