Abstract
A building air conditioning system using geothermal energy comprising an underground pipe being buried underground for transmitting geothermal energy from the underground to air from the outdoors and for controlling humidity of said air and cleaning said air, a cobble stone layer constituted by filling numerous cobble stones in a space under the floor of a building for introducing air from said underground pipe to heat-exchange this introduced air with geothermal energy stored therein and to control humidity of said air and to clean said air, and air supply means for supply air from said cobble stone layer to an inside of a room of the building.
Claims8
A building air conditioning system using geothermal energy, comprising:
- an underground pipe having a length within the range of from approximately 1 m to approximately 10 m, said underground pipe buried underground for introducing air from the outdoors into the inside thereof so as to transmit geothermal energy from the underground to said introduced air,
- a cobble stone layer constituted by filling numerous cobble stones in a space under the floor of a building, said cobble stone layer having a height within the range of from approximately 250 mm to approximately 1,000 mm, said cobble stone layer storing geothermal energy in said numerous cobble stones and air layers existing in minute clearances between said numerous cobble stones, said cobble stone layer introducing said air to be transmitted geothermal energy in said underground pipe into the inside thereof, said cobble stone layer heat-exchanging said introduced air with geothermal energy stored in said numerous cobble stones and said air layers, controlling humidity of said air by attaching water vapor contained in said air onto the surface of said numerous cobble stones when much-moisturized air moves in said cobble stone layer and by supplying moisture deposited on the surface of said numerous cobble stones to said air when dry air moves in said cobble stone layer, and cleaning said air by attaching minute impurities such as dust contained in said air onto moisture deposited on the surface of said numerous cobble stones when said air moves in said cobble stone layer, and
- air supply means for supply said air from said cobble stone layer to an inside of a room of the building.
