Description

{Ground heat exchange pipe spacer}

The present invention relates to a geothermal heat exchange band spacer, and more particularly, to a geothermal heat exchange band spacer which is coupled to a geothermal heat exchange band installed in a borehole formed on a ground surface and separates an inlet pipe and an outlet pipe constituting the heat exchange band. Spacers.

In general, fossil fuels such as coal, petroleum and natural gas are used as energy sources for domestic and industrial use. These fossil fuels are rapidly increasing in cost due to depletion of the reserves, and various pollutants Polluting water quality and the atmospheric environment. In recent years, attempts have been made to utilize geothermal energy as an environmentally friendly alternative energy capable of replacing fossil fuels. In the case of the cooling / heating apparatus using the geothermal heat, the energy saving can be maximized by 40% or more compared to the conventional heating / cooling apparatus, and stable operation can be achieved without deteriorating the cooling / heating performance due to the geothermal characteristic that maintains a constant temperature during the year.

1 is a view for explaining a state where a conventional geothermal heat exchange band is inserted into a bore hole. 2 is a view for explaining a state in which a band supply roll device for transporting a geothermal heat exchange band is disposed close to a bore hole.

As shown in the figure, the geothermal heat exchange band (B) is connected to a heat pump to perform cooling and heating, and includes an inlet pipe (B1) through which a heating medium flows and an outlet pipe (B2) through which a heating medium flows. In order to apply the heat exchange band B to the boreholes H drilled at a depth of about 100 to 300 m from the ground, the heat exchange band B is first inserted to the bottom of the bore hole H, A tremie pipe for supplying the grouting G is inserted to the bottom of the hole H and then the grouting G is supplied while gradually discharging the tube from the hole H by bending. Through this process, the interior of the borehole H is filled with the grouting G to complete the construction of the geothermal heat exchange band B.

With this structure, the heating medium flowing into the inflow pipe (B1) and then flowing out to the outflow pipe (B2) is subjected to heat exchange with the geothermal heat transmitted through the grouting (G), and the heat medium is heated by a heat pump Exchanged again and used for cooling and heating.

The depth of the boreholes H is in the range of 100 to 300 m in the construction of the heat exchanging band of the above-mentioned type. Therefore, the inflow pipe B1 and the outflow pipe B2 inserted in the borehole H are irregular And often have irregular orientations. In this case, it was difficult to insert the bridge pipe to the bottom of the bore hole (B), and the grouting work was delayed.

In addition, it interferes with the heat exchange of the geothermal heat at the twisted part of the inflow pipe (B1) and the outflow pipe (B2), and especially the air gap (A) in which the grouting (G) is not filled is generated at the twisted part, Respectively.

Accordingly, a spacer for maintaining the interval between the inlet pipe B1 and the outlet pipe B2 of the heat exchange band inserted into the borehole H has been developed, and a related art related to this is disclosed in Japanese Patent Application No. 10-2012-0077935, And an installation method thereof have been disclosed.

However, since the heat exchange band B is carried in a wound state on the band feed roll R in tens of meters, as shown in FIG. 2, in order to insert the heat exchange band B into the bore hole H The operation of coupling the spacer to the heat exchange band B in a narrow space between the borehole H and the band feed roll unit R has to be carried out near the borehole H It went on.

As such, since the spacers must be coupled to the heat exchange band B at intervals of several meters, it is necessary to couple dozens of spacers to one heat exchange band B as a result. Therefore, a spacer structure is required to allow the operator to easily join the heat exchange band B in a narrow space.

After the heat exchange band B with the spacer is fully inserted into the borehole H, a thermal pipe for supplying the grouting G must be inserted into the borehole H. However, since the heat exchange band (B) is coupled with dozens of spacers, the tube is caught by the spacer and the insertion process is interrupted. Therefore, a spacer structure is required to prevent the insertion of the tube.
