Patent ID: 8662147

Claim:
A geothermal air-conditioner device; comprising: a first pressure reducing chamber ( 1 ) with an air intake opening ( 8 ); a second pressure reducing chamber ( 2 ) with a processed air outlet ( 9 ); wherein the first and second pressure reducing chambers ( 1 , 2 ) are connected to each other with air conduits ( 3 ) located in the ground for conveying air from the first pressure reducing chamber ( 1 ) to the second pressure reducing chamber ( 2 ); wherein a ground layer ( 4 ) covering air conduits ( 3 ) is covered with a coarse material layer ( 5 ), which is covered by a coating layer ( 11 ); at least one first ventilation conduit ( 6 ) extends into the coarse material layer ( 5 ) through the coating layer ( 11 ) for connecting the coarse material layer ( 5 ) to air in the first reducing chamber ( 1 ); an exhaust ventilation piping ( 7 ) located in the coarse material layer ( 5 ) for providing exhaust from coarse material layer ( 5 ); a fan or other ventilation device ( 19 ) is connected to an outlet ( 9 ) of the second pressure reducing chamber ( 2 ); wherein the air conduits ( 3 ) are bent by approximately 110-170 degrees of a bending angle α with a bending point facing upwards, so that at the beginning intake air will flow upwards by an angle β of approximately 10-17 degrees from the horizontal and after bend angle α in air conduits ( 3 ) the air will flow downwards relative to the horizontal to the second pressure reducing chamber ( 2 ); and a check valve ( 14 ) is provided at one end of the first ventilation conduit ( 6 ) close to the first pressure reducing chamber ( 1 ).
