<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner of low energy costs and a simple structure, capable of suppressing waste consumption of artificial energies such as petroleum, gas and electricity, and effectively utilizing solar heat and geothermal heat in the ground to control a room temperature of a house. <P>SOLUTION: The fresh outside air sucked by a total heat exchange type ventilator mounted in a room of a building, is distributed to an underfloor section of a first story of the building, a plurality of U-shaped geothermal heat recovery pipes are embedded in a foundation under the floor of the first story, blowers are mounted on one end of the geothermal heat recovery pipes, and the air sucked to the geothermal heat recovery pipes is heated in the geothermal heat recovery pipes by geothermal heat in winter, and cooled in the geothermal heat recovery pipe by the geothermal heat in summer, so that the temperature of the air in the underfloor section of the first story is conditioned. The temperature-conditioned air is supplied to the inside of a ceiling of each story through an air supply duct, and further supplied indoors from louvers disposed on the ceilings. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
