본 발명은 지열 및 지하수공의 내부케이싱 설치구조에 관한 것으로, 내부 케이싱과 관정 사이의 공간에 충진재를 균일하게 충진하여 전 영역에서 동일한 열교 환 효율을 얻을 있도록 한 지열 및 지하수공의 내부케이싱 설치구조에 관한 것이다.The present invention relates to an internal casing installation structure of geothermal and ground water holes, the internal casing installation structure of geothermal and ground water holes to uniformly fill the space between the inner casing and the wells to obtain the same heat exchange efficiency in all areas It is about.

일반적으로 지열을 이용하여 냉난방의 에너지로 활용하기 위한 방법으로는, 지반내 일정깊이에 관을 매설하고 그 관속에 냉매를 강제 순환시켜 냉매가 순환되는과정 중 지반내에서 흡수한 열에너지를 냉난방 에너지로 활용하는 매설식 방법과, 암반을 일정깊이로 천공한 후 그곳에 공내시설물(수중펌프, 파이프, 모타전선 등)을 설치하여 천공된 관정내 집수된 지하수를 지상으로 끌어 올려 열교환 과정을 마친 지하수를 순환관을 통해 관정 내부로 다시 유입시키는 그러한 과정 중 흡수된 열에너지를 이용하여 냉난방 시스템의 에너지로 활용한 방법이 있다. 상기 지하수를 열원으로 이용한 방법은 전술한 관 매설식 방법에 비해 열에너지를 효율적으로 이용할 수 있다는 장점이 있어서 최근 주로 이용되고 있다.In general, a method of utilizing geothermal heat as energy for cooling and heating is to embed a pipe at a certain depth in the ground, and forcibly circulate the refrigerant in the tube to convert heat energy absorbed from the ground into cooling and heating energy. Utilize the buried method and the underground water after finishing the heat exchange process by drilling the rock to a certain depth and then installing the internal facilities (submersible pump, pipe, motor wire, etc.) to the ground and collecting the groundwater collected in the drilled well to the ground. There is a method of using the absorbed heat energy as energy of the heating and cooling system during the process of flowing back into the well through the pipe. The method using the groundwater as a heat source has been mainly used recently because it has an advantage that the thermal energy can be efficiently used as compared to the pipe embedding method described above.

지하수를 열원으로 이용한 방법은 수중펌프를 통해 지하수를 강제 이송시켜 열교환을 통해 하절기에는 실내를 냉각하고 동절기에는 실내를 난방토록 한 구조로서 일반적으로 도 1에 도시된 바와 같은 구성을 지닌다.In the method using groundwater as a heat source, the groundwater is forcedly transferred through an underwater pump to cool the room in summer and heat the room in winter, and has a configuration as shown in FIG. 1.

도 1에서 보이는 것처럼, 종래 기술에 의한 지열을 이용한 지열 및 지하수공의 내부케이싱 설치구조는, 에어 해머 드릴 등의 천공기로 지중에 형성되는 관정(1), 관정(1)의 붕괴 방지를 위하여 관정(1)의 내벽 설치되는 관형의 외부 케이싱(2), 관정(1) 내부에 삽입되며 순환관(3)을 통해 열교환기(4)와 연결되어 지하수를 펌핑하여 열교환기(4)에 공급하는 수중펌프(5)로 이루어진다.As shown in FIG. 1, the internal casing installation structure of geothermal and groundwater holes using geothermal heat according to the prior art is provided to prevent the collapse of the well (1) and well (1) formed in the ground with a perforator such as an air hammer drill. (1) the inner wall of the tubular outer casing (2), which is inserted into the inside of the well (1) and connected to the heat exchanger (4) through the circulation pipe (3) pumping groundwater to supply to the heat exchanger (4) It consists of a submersible pump 5.

지반 상태가 연약하여 붕괴의 우려가 있는 경우 관정(1) 및 수중펌프(5)의 보호와 원활한 지하수의 공급을 위하여 내부 케이싱(6)이 적용된다.If the ground condition is weak and there is a fear of collapse, the inner casing 6 is applied for the protection of the well 1 and the submersible pump 5 and the smooth supply of groundwater.

내부 케이싱(6)은 다수의 유입공(6a)을 갖으며 관정(1)의 바닥에 근접되는 길이의 관형이며 외부 케이싱(1) 내부에 삽입 설치된다.The inner casing 6 has a plurality of inlet holes 6a and is tubular in length close to the bottom of the well 1 and is inserted into the outer casing 1.

이와 같은 구조의 지열 및 지하수공의 내부케이싱 설치구조에 따르면, 수중펌프(5)의 펌핑에 의해 지하수가 내부 케이싱(6)을 통과하여 열교환기(4)에 공급되고, 열교환기(4)를 통해 열교환된 지하수는 다시 내부 케이싱(6)과 관정(1) 사이에 복귀되어 관정(1) 바닥측으로 내려가면서 열교환되어 원상태로 복원된 후 다시 내부 케이싱(6)을 통해 열교환기(4)에 공급된다.According to the internal casing installation structure of the geothermal and ground water hole of such a structure, the groundwater is supplied to the heat exchanger (4) through the inner casing (6) by the pumping of the submersible pump (5), the heat exchanger (4) The groundwater heat exchanged through is returned between the inner casing (6) and the well (1) again and is exchanged to the bottom of the well (1) to be restored to its original state, and then supplied to the heat exchanger (4) again through the inner casing (6). do.

이와 같이 열교환기(4)를 통과한 후 복귀되는 지하수는 관정(1) 내부를 흐르면서 열교환할 때 열교환효율을 높이기 위하여 내부 케이싱(6)과 관정(1)의 사이에는 충진재(7)가 채워진다. 충진재(7)는 잔자갈, 왕사, 여과사 등으로서 복귀되는 지하수의 유속을 저속으로 유도하여 열교환 시간을 길게 함으로써 열교환 효율을 높이게 된다.As such, the groundwater returned after passing through the heat exchanger 4 is filled with a filler 7 between the inner casing 6 and the well 1 in order to increase the heat exchange efficiency when the heat is exchanged while flowing inside the well 1. The filler material 7 increases the heat exchange efficiency by inducing the flow rate of groundwater returned as residue, coarse sand, filtered sand, etc. at a low speed to lengthen the heat exchange time.

그러나, 종래 기술에 의한 지열 및 지하수공의 내부케이싱 설치구조는 다음과 같은 문제점이 있다.However, the internal casing installation structure of geothermal and groundwater holes according to the prior art has the following problems.

관정(1)을 천공하는 에어 해머 드릴 등의 장비가 발전되고 있긴 하지만, 지반 내의 암반의 강도 차이에 의해 관정(1)을 수직으로 형성하지 못하고 도 2와 같이 굴곡지게 형성할 수밖에 없는 상황이 발생된다. 이처럼 관정(1)이 굴곡진 경우 내부 케이싱(6)이 관정(1)의 중심에 셋팅되지 못하여 충진재(7)가 내부 케이싱(6)과 관정(1) 사이 공간에 균일하게 채워지지 못하게 되며, 결과적으로 지하수가 충 진재(7)가 타구간 보다 적게 채워지거나 채워지지 못한 구간을 통과하는 동안에는 열교환효율이 떨어지므로 열교환기(4)에 원하는 온도의 지하수를 공급하지 못하는 문제점이 있다.Although equipment such as an air hammer drill for drilling the well 1 is being developed, there is a situation in which the well 1 cannot be formed vertically but bent as shown in FIG. 2 due to the difference in strength of the rock in the ground. do. As such, when the well 1 is curved, the inner casing 6 may not be set at the center of the well 1 so that the filler 7 may not be uniformly filled in the space between the inner casing 6 and the well 1, As a result, since the heat exchange efficiency decreases while the groundwater 7 fills or fills less than the other section, there is a problem in that the groundwater of the desired temperature cannot be supplied to the heat exchanger 4.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 내부 케이싱과 관정 사이의 공간에 충진재를 균일하게 충진하여 전 영역에서 동일한 열교환 효율을 얻을 수 있도록 한 지열 및 지하수공의 내부케이싱 설치구조를 제공하려는데 그 목적이 있다.The present invention is to solve the problems as described above, to provide an internal casing installation structure of geothermal and ground water holes to uniformly fill the space between the inner casing and the wells to obtain the same heat exchange efficiency in all areas I want to do that.

전술한 바와 같은 목적을 달성하기 위한 본 발명에 의한 지열 및 지하수공의 내부케이싱 설치구조는, 관정 내부에 삽입되는 내부 케이싱의 둘레부에 하나 이상의 센터유지구가 결합되어 상기 내부 케이싱이 상기 관정의 중심에 배치되도록 유도하는 것을 특징으로 한다.In the inner casing installation structure of the geothermal and ground water hole according to the present invention for achieving the object as described above, one or more center holders are coupled to the circumference of the inner casing is inserted into the well, so that the inner casing of the well It is characterized by inducing to be arranged in the center.

이와 같이 구성된 본 발명에 의한 지열 및 지하수공의 내부케이싱 설치구조의 작용은 다음과 같다.The action of the inner casing installation structure of geothermal and groundwater holes according to the present invention configured as described above are as follows.

내부 케이싱(10)의 둘레부에 센터유지구(10)를 조립하며, 센터유지구(10)의 조립은 도 4, 도 6, 도 7a, 도 8b에서 구체적으로 설명하였다.The center holder 10 is assembled to the periphery of the inner casing 10, and the assembly of the center holder 10 has been described in detail with reference to FIGS. 4, 6, 7A, and 8B.

지중에 관정(1)을 형성한 후, 이 관정(1) 내부에 내부 케이싱(6)(센터유지구(10)가 조립된 상태)을 삽입한다. 내부 케이싱(6)의 삽입시 센터유지구(10)의 지지부(12)(또는 21)가 관정(1)의 내벽에 지지된 상태로 내부 케이싱(6)이 삽입되어 내부 케이싱(6)이 관정(1)의 중심에 위치하게 된다. After the well 1 is formed in the ground, an inner casing 6 (a state in which the center holder 10 is assembled) is inserted into the well 1. When the inner casing 6 is inserted, the inner casing 6 is inserted with the support 12 (or 21) of the center holder 10 supported by the inner wall of the well 1 so that the inner casing 6 is inserted into the well. It is located in the center of (1).

한편, 도 11과 같이, 관정(1)이 직선을 유지하지 못할 경우에도 센터유지 구(10)의 지지부(12)(또는 21)가 항상 관정(1)의 내벽면에 지지되고 지지부(12)(또는 21)의 길이가 변하지 않기 때문에 내부 케이싱(6)이 탄성 변형되어 관정(1)의 중심에 위치하게 된다.On the other hand, as shown in FIG. 11, even when the well 1 does not maintain a straight line, the support 12 (or 21) of the center holder 10 is always supported on the inner wall surface of the well 1 and the support 12 is supported. Since the length of (or 21) does not change, the inner casing 6 is elastically deformed and positioned at the center of the well 1.

이어서, 내부 케이싱(6)과 관정(1) 사이에 충진재(7)를 채워 시공을 마무리한다. 내부 케이싱(6)과 관정(1) 사이의 간격이 센터유지구(10)(또는 커플러(20))를 통해 동일하므로 내부 케이싱(6)과 관정(1) 사이의 모든 영역에 동일한 양의 충진재(7)가 채워질 수 있다.Subsequently, the filling material 7 is filled between the inner casing 6 and the well 1 to finish the construction. Since the spacing between the inner casing 6 and the well 1 is the same through the center holder 10 (or coupler 20), the same amount of filler in all areas between the inner casing 6 and the well 1 (7) can be filled.

이와 같이 설치된 상태에서 기기의 작동을 개시하면 수중펌프(5)의 펌핑에 의해 지하수가 내부 케이싱(6)의 유입공(6a)을 통해 유입되어 열교환기(4)에 공급된다. 열교환기(4)에 공급된 지하수는 열교환매체와 열교환한 후 내부 케이싱(6)과 관정(1) 사이에 복귀되어 관정(1)의 바닥으로 흐르게 되며, 이 과정에서 충진재(7)를 통과하여 열교환효율이 높아진다. 이때, 내부 케이싱(6)과 관정(1) 사이의 모든 영역에 충진재(7)가 균일하게 채워져 관정(1)에 복귀되는 모든 지하수가 동일하게 열교환되어, 원하는 온도의 지하수가 지속적으로 공급될 수 있다.When the operation of the device is started in this state, the groundwater is introduced through the inlet hole 6a of the inner casing 6 by the pumping of the submersible pump 5 and supplied to the heat exchanger 4. Groundwater supplied to the heat exchanger (4) is exchanged between the inner casing (6) and the well (1) after the heat exchange with the heat exchange medium flows to the bottom of the well (1), in the process passes through the filler (7) Heat exchange efficiency becomes high. At this time, the filling material 7 is uniformly filled in all regions between the inner casing 6 and the well 1 so that all ground water returned to the well 1 can be heat-exchanged equally so that the ground water at a desired temperature can be continuously supplied. have.

이상에서 설명한 바와 같이, 본 발명에 의한 지열 및 지하수공의 내부케이싱 설치구조에 의하면, 지반의 상태로 인하여 관정이 직선을 유지하지 못하고 굴곡지게 형성되는 경우에도 내부 케이싱과 관정 사이의 간격이 동일하여 전 영역에 걸쳐 동일한 양의 충진재가 채워짐으로써 동일한 조건 하에서 열교환이 이루어지므로 열 교환효율을 높일 수 있고 최적 온도의 지하수가 지속적으로 공급됨에 따라 지열을 이용한 열교환장치의 신뢰성을 향상할 수 있다.As described above, according to the internal casing installation structure of the geothermal and ground water hole according to the present invention, even if the wells are formed to be curved due to the ground state is not kept straight, the distance between the inner casing and the wells is the same Since the same amount of filler is filled over the entire area, the heat exchange is performed under the same conditions, thereby increasing the heat exchange efficiency and improving the reliability of the geothermal heat exchanger using the groundwater at the optimum temperature.
