<P>PROBLEM TO BE SOLVED: To obtain a relatively simple structure for heating and cooling a building, which can efficiently use underground geothermy and brings about a great air-conditioning effect. <P>SOLUTION: At least one pipe (10) and (10) for bringing up the geothermy is buried in ground (9) under a floor of the building; internal spaces (12) of the pipes (10) and (10) and an underfloor space (4) are made to communicate with each other; and a space extending from the internal spaces (12) to the underfloor space (4) is filled with heat storing stone (6), (6), etc., such as gravel. <P>COPYRIGHT: (C)2003,JPO |
