る。As described above, since the outer tube 2 of the tube 1 is made of a steel tube which can be rotationally press-fitted into the ground, the outer tube 2 can be extremely easily grounded by using a rotary press-fitting pile driving machine. It can be driven deep into the inside 13, whereby the tube 1 can be embedded deep inside the ground 13. Moreover, there is no need to drill holes in the ground or backfill the soil.
Since it suffices to directly drive the outer steel pipe into 3, the cost required for the tube embedding work can be kept low.

According to the embedding method by rotary press-fitting as described above, the tube 1 can be extremely easily embedded even at a depth exceeding 10 m, and the air conditioning by utilizing the underground heat can be highly effective.

The tube 1 is driven into the ground under the floor of the building, the outside air intake 11 is opened to the underfloor space portion 14, and the upper end of the tube 1 is connected to the air outlet 16 provided on the floor 15. 17 is a filter, and the sound of the fan 12 is indoors 1
It is preferable to use a sound-insulating filter that suppresses the transmission of the noise. Further, reference numeral 18 is a filter such as an insect screen, which prevents insects and dust from being sucked into the tube 1.

The air inside is sucked into the annular ventilation part 7 in the tube 1 through the intake port 11 and descends through the annular ventilation part 7, and in the process of this descending, the underground heat and the heat are passed through the pipe wall of the outer pipe 2. They are exchanged and are cooled by geothermal heat in summer and warm by geothermal heat in winter. The outer tube 2 is made of a steel tube with good thermal conductivity,
Moreover, since it is buried deep in the ground, heat exchange with the underground heat is effectively performed. Then, the heat-exchanged air is sucked into the inner pipe 6 through the vent hole 8 at the lower end of the inner pipe 6, rises in the ventilation part 9 in the inner pipe 6, and flows from the upper end of the outer pipe 2 through the blowing part 16 in the summer season. Is cool air indoors 1
It blows out to 9 and warm air blows out indoors 19 in winter.

The inner tube 6 is preferably made of a material or structure having excellent heat insulating properties so that the air that rises in the air passage 9 in the inner tube 6 does not exchange heat.

When the air is driven, the outside air exchanges heat with the underground 13 and is cooled to cause dew condensation, and condensed water is collected at the bottom of the outer tube 2, so that the outer tube 2 of the tube 1 has an annular ventilation part. A drainage pipe 20 is inserted through 7, and the dew condensation water can be discharged to the outside through this pipe 20. In order to prevent adverse effects due to corrosion such as rust of the outer steel pipe 2 due to water such as dew condensation water, it is necessary to increase the thickness of the outer steel pipe 2 or provide a coating layer on the wall surface of the outer steel pipe 2. It is good to leave it.

にしてもよい。Further, in the example of FIG. 3, the load from the concrete foundation 21 of the building is transmitted to the outer steel pipe 2 of the tube 1, so that the tube 1 also functions as a pile. ing. That is, a steel side projection 22 is attached to the outer steel tube 2 of the tube 1 in a cantilevered state, and this side projection 22 is projected to the lower surface side of the building foundation 21 to The load is transmitted to the outer steel tube 2 of the tube 1 via the lateral protrusions 22. In this way, by using the side protrusions 22 to transfer the load from the building foundation 21 to the outer tube 2 of the tube 1, the tube 1 is made to work as a pile without being embedded right under the foundation 21. Therefore, the air that has passed through the inside of the tube 1 and exchanged heat with the underground heat can be sent into the interior 19 with a simple ventilation structure. of course,
The tube 1 may be driven directly below the foundation 21 to support the foundation 21, or the tube may be driven into the outdoor ground to support the foundation 21 of the building by the lateral protrusions.

As a result, it is possible to install the geothermal heat utilization air conditioning system with great cost advantage.

の場合、拡底翼５などは省略されてもよい。In the installation example shown in FIG. 4, the tube 1 is installed by driving it into the underground 13 under the floor of the building so that the outer steel tube 2 is a tube exclusively for air conditioning using geothermal heat that does not receive the load from the foundation of the building. Here is an example. In this way, the tube 1 may have an installation structure that does not function as a pile. In that case, the bottom expanding blades 5 and the like may be omitted.

うまでもない。Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, regardless of whether or not the outer tube of the tube functions as a stake, a plurality of blades, such as a spiral protruding laterally, are provided at the outer peripheral portion of the outer tube at intervals in the longitudinal direction. As a result, it is possible to enhance the installation stability of the tube and also to enhance the heat exchange efficiency between the air passing through the tube and the underground heat. of course,
Whether or not the outer tube of the tube functions as a pile,
The bottom expanding blades and the like may be omitted. Further, it is needless to say that the structure inside the tube is not particularly limited and can be applied to a vertical tube for air conditioning using geothermal heat having various internal structures.
