<P>PROBLEM TO BE SOLVED: To provide a geothermal air-conditioning system that efficiently cools or warms air in living space inside a building utilizing geothermal heat and that is easy to maintain and relatively inexpensive to build. <P>SOLUTION: An underground space 8 is formed below a building 10 and a nonliving space 8a facing the wall surface or the floor surface of the underground space 8 is provided in at least a portion of the underground space. Other spaces including the inside of the building are formed into living spaces 7, 8b. The nonliving space 8a is separated from the living spaces 7, 8b by a heat insulator 12 to form a structure that allows geothermal heat to accumulate in the nonliving space 8a. A heat exchange between the heat accumulated in the nonliving space 8a and the heat accumulated in the living spaces 7, 8b is performed to cool or warm the living space 7. <P>COPYRIGHT: (C)2007,JPO&INPIT |
