PURPOSE:To absorb efficiently the air heat in the space in the ceiling and be able to cool the space by installing continuously primary and secondary receivers for dew condensation water which are formed with specified material and installed under a heat exchanging pipe which is installed in the ceiling and to which cooling water is supplied. CONSTITUTION:Primary receivers 6 for dew condensation water formed with high-conductive material are installed under a meandering heat exchanging pipe 5. Under the primary receivers 6 secondary receivers 7 for dew condensa tion water formed with low-conductive material are installed. When cooling water is circulated in the pipe 5, the air heat in the space 4 in the ceiling is absorbed by the pipe 5 and the air is cooled. The dew condensation water generated on the periphery of the pipe 5 falls down on the receivers 6 and even by the receivers 6 the air heat in the space 4 is absorbed and the dew condensation water is discharged through recessed groove parts 6a. The dew condensation water generated on the receivers 6 is recovered by the receivers 7 and then discharged and the dew condensation water is not generated on the receivers 7. Thereby, the interior of a room is kept at the optimum temp.
