PROBLEM TO BE SOLVED: To provide a ceiling radiation system capable of sufficiently cooling the inside of room with high efficiency. SOLUTION: When cold water is poured in a plurality of heat radiation tubes 110, the inside of room is cooled by heat radiation of the heat radiation tubes 110 and heat radiation plates 140. When the cold water sufficiently cooled flows, dew condensation moisture is generated on surfaces of the heat radiation tubes 110 and the heat radiation plates 140, but the dew condensation moisture is recovered by a drain 150. As cooling performance of each of the plurality of heat radiation tubes 110 is enhanced by the heat radiation plates 140, and the dew condensation moisture on the heat radiation tubes 110 and the heat radiation plates 140 can be surely recovered by the drain 150, the cold water sufficiently cooled can be allowed to flow to the heat radiation tubes 110, and the inside of room can be sufficiently cooled. Further as the air cooled by the heat radiation tubes 110 and the heat radiation plates 140 can be circulated indoors from a clearance of the drain 150, the inside of room can be sufficiently cooled.
