CONSTITUTION:The batten B made of latent heat type heat accumulating plate C closes up tightly the space in the ceiling A formed between the batten B and the ceiling E. The fan 3 is arranged on the ceiling E. The fan 3 is arranged on the ceiling A to the interior of the room through a duct 1, the inside of a wall 4, a blowing-off port la and reflux openings 2. Owing to the structure as described above, the heat accumulating plate C absorbs the solar heat during the time when the sun is shining in order to accumulate therewithin and as well as heats the air in the space in the ceiling A.
