<P>PROBLEM TO BE SOLVED: To reduce necessary power for a heat exhausting fan. <P>SOLUTION: A head-side air conditioning unit 60 housed in a head board 20 comprises a heat exhaust-side passage 6b extending in the vertical direction. The heat exhaust-side passage 6b has a heat exhaust-side blowout opening 67 at an upper position of a heat exhaust-side heat exchanging portion 73. Accordingly, the air for exhausting heat is exhausted along the upward flow of the air for heat exhaust, heated by the heat exhaust-side heat exchanging portion 73. Thus the necessary power of the heat exhausting fan 77 can be reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT |
