<P>PROBLEM TO BE SOLVED: To provide a new air conditioner using an underground heat exchanger and capable of removing powder dust in the air. <P>SOLUTION: In this air conditioning mechanism utilizing the underground heat exchanger of a mechanism where the underground heat exchanger having a double tube structure constituted by freely fitting an inner tube opened at its both ends to an outer tube closed at its tip and opened at the other end, is buried in the ground in a state that the tip of the outer tube faces downward, and then the conditioned air is allowed to flow to a clearance between the outer tube and the inner tube to exchange heat with ground heat, collide with a bottom of the outer tube and turn back through the inner tube, the water is stored in a bottom portion of the outer tube, and the air flowing in from the clearance between the outer tube and the inner tube is collided with a liquid level of the water stored in the bottom portion of the outer tube to remove powder dust and/or chemical substances in the air. A flow velocity of the air collided with the liquid level of the water is 1.5 m/sec or more. <P>COPYRIGHT: (C)2008,JPO&INPIT |
