Especially, the road surface outside the tunnel has a much faster melting rate of snow due to the shade of mountainous terrain. Because of the slowness, if the snow accumulated on the road surface outside the tunnel is not quickly removed, the road freezes and traffic accidents occur frequently.

The road surface heat collecting portion A is heated by solar heat irradiated to the road surface, and functions to heat and heat the liquid heat medium in the endothermic / heating pipe portion 31 installed in the basement of the road surface.
태양열 집열기(10)는 태양열을 모아서 액상 열매체를 가열하는 기능을 한다. 태양열 집열기(10)는 태양일사를 효과적으로 수집, 이용하기 위하여 설치한 시설물로서 흡열판, 투명덮개, 단열재 등으로 구성되어 있으며, 공기집열식, 액체집열식이 있다. 본 발명에서는 액상인 열매체에 태양열을 모으는 액체 집열식 태양열 집열기(10)가 이용될 수 있다. 여기서 열매체로는 오염 문제-*-가 발생될 여지가 없는 물을 사용할 수 있다. 한편, 본 발명에서 태양열 집열기(10)는 노면 집열부(A)의 집열 기능을 보조하여 예비적으로 태양열을 집열하여 액상 열매체를 가열하는 기능을 한다. The solar collector 10 functions to collect solar heat and heat the liquid heat medium. Solar collector 10 is a facility installed in order to effectively collect and use solar radiation is composed of a heat absorbing plate, a transparent cover, a heat insulator, etc., there are air-collecting, liquid-collecting.

On the other hand, in the present invention, the solar collector 10 serves to collect the solar heat preliminarily by assisting the heat collecting function of the road surface heat collecting portion A to heat the liquid heat medium.
계간 축열 저장조(20)는 상기 태양열 집열기(10)에 의해 가열된 액상 열매체를 저장하며, 지표면 이하에 설치되며, 여름철의 열원을 저장한 후, 겨울철에 상기 가열된 액상 열매체를 사용하게 하는 기능을 한다. 계간 축열 저장조(20)는 태양열의 계절적 수급 격차를 대응하기 위한 시스템으로서, 지중에 설치되어서, 대용량의 열매체를 저장하고, 80~ 98℃ 까지 가열된 열매체를 저장하는 장치이다. 본 발명에서 계간 축열조(20)는 기본적으로 도로면으로 조사하는 태양열에 의해 가열되는 배관부(31)의 축열 열매체를 저장하고 예비적으로는 태양열 집열기(10)에 의해 가열된 축열 열매체를 저장한다. The quarterly heat storage tank 20 stores the liquid heat medium heated by the solar collector 10, is installed below the ground surface, and stores a heat source in summer, and then uses the heated liquid heat medium in winter. do. Quarterly heat storage tank 20 is a system for coping with the seasonal supply and demand gap of solar heat, is installed in the ground, and stores a large heat medium, and a heat medium heated to 80 ~ 98 ℃. In the present invention, the quarterly heat storage tank 20 basically stores the heat storage medium of the piping portion 31 heated by solar heat irradiated to the road surface, and preliminarily stores the heat storage heat medium heated by the solar heat collector 10. .
본 발명에서는 도로 결빙 효율 및 축열 효율을 높이기 위하여, 계간 축열 저장조(20)의 단면이 역사다리꼴을 가지며, 상부와 하부를 구분하는 다공판(70: 도 5 참조)이 내장되며, 다공판(70)의 위에는 다수의 구형 축열재(80)가 배치되게 된다. 이 계간 축열 저장조(20)의 구조에 대해서는, 도 5에서 보다 상세하게 설명하도록 한다. In the present invention, in order to increase the road freezing efficiency and heat storage efficiency, the cross section of the intermittent heat storage storage tank 20 has an inverted trapezoidal shape, and a perforated plate 70 (see FIG. 5) that separates the upper part and the lower part is embedded and the porous plate 70 The plurality of spherical heat accumulators 80 are arranged above. The structure of the interlayer storage tank 20 will be described in more detail with reference to FIG. 5.
도로면에 설치된 흡열/가열 배관부(31)를 포함하는 결빙 방지부(30)는, 계간 축열 저장조(20)에 저장된 고온의 액상 열매체가 유동하여 도로면을 가열시켜서 도로 결빙을 방지하는 구조를 가진다. 또한, 특히 여름철 주간에 도로면으로 조사되는 태양열에 의해 상기 흡열/가열 배관부(31)에 유동하는 액상 열매체는 가열되어서 회수관(60)을 통해 계간 축열 저장조(20)에서 저장되게 된다. 여름철 뿐 아니라 겨울철 주간에 열매체를 가열하여 저장한 후, 야간에 결빙 방지로 사용할 수도 있다. 이와 같이 상대적으로 넓은 면적의 도로면이라는 노면 집열부(A)로 조사되는 뜨거운 태양열을 액상 열매체에 저장함으로써 태양열 이용 효율을 극대화할 수 있게 된다. The freezing prevention part 30 including the endothermic / heating pipe part 31 provided on the road surface has a structure that prevents road freezing by heating a road surface by heating a high temperature liquid heat medium stored in the interlayer heat storage storage tank 20. Have In addition, the liquid heat medium flowing in the endothermic / heating pipe part 31 by solar heat irradiated to the road surface during the summer day is heated and is stored in the intermittent heat storage storage tank 20 through the recovery pipe 60. It can be used to prevent the freezing at night, after heating and storing the heat medium during winter as well as summer. Thus, by storing the hot solar heat irradiated to the road surface heat collecting portion (A) of the road surface of a relatively large area in the liquid heat medium, it is possible to maximize the solar heat utilization efficiency.
제 1 순환펌프(40)는 계간 축열 저장조(20)에 있는 액상 열매체를 결빙 방지부(30)의 흡열/가열 배관부(31)로 공급하고, 다시 흡열/가열 배관부(31)에서 계간 축열 저장조(20)로 회수하기 위한 구성요소이다. 도시된 바와 같이 제 1 순환 펌프(40)는 계간 축열 저장조(20)와 급수관(50) 및 회수관(60) 사이에 설치된다. 이에 따라 제 1 순환 펌프(40)에 의해, 겨울철 도로면 결빙이 예상되는 경우, 급수관(50)을 통해 흡열/가열 배관부로 축열 액상 열매체를 흡열/가열 배관부(31)로 공급하여 도로면을 가열함으로서 결빙을 예방하거나 제거하게 된다. 또한, 여름철 주간과 같이 뜨거운 태양열이 도로면을 가열하는 경우, 흡열/가열 배관부(31)에 있는 액상 열매체는 축열되어서(즉, 흡열하여서) 제 1 순환 펌프(40)에 의해 계간 축열 저장조(20)로 공급되어서 저장되게 된다. The first circulation pump 40 supplies the liquid heat medium in the heat storage reservoir 20 to the endothermic / heating piping part 31 of the frost protection part 30, and again accumulates the quarterly heat storage / heating pipe part 31. It is a component for recovery to the reservoir 20. As shown, the first circulation pump 40 is installed between the quarterly heat storage tank 20 and the water supply pipe 50 and the recovery pipe 60. Accordingly, when the winter road surface freezing is expected by the first circulation pump 40, the heat storage liquid heat medium is supplied to the endothermic / heating pipe part through the water supply pipe 50 to the endothermic / heating pipe part 31 to supply the road surface. Heating prevents or eliminates freezing. In addition, when hot solar heats the road surface, such as during the summer day, the liquid heat medium in the endothermic / heating pipe part 31 is thermally stored (that is, endothermic) so that the first storage pump 40 stores the interlayer heat storage tank ( 20) to be supplied and stored.
제 2 순환 펌프(40)는 계간 축열 저장조(20)와 태양열 집열기(10)간의 열매체간의 유동을 일으키는 역할을 한다. 즉, 태양열 집열기(10)에 의해 가열된 열매체가 계간 축열 저장조(20)로 이동시키고, 또한 계간 축열 저장조(20)의 가열이 필요한 열매체를 태양열 집열기(10)로 이동시키도록 한다. The second circulation pump 40 plays a role of causing flow between the heat medium between the heat storage reservoir 20 and the solar collector 10. That is, the heat medium heated by the solar heat collector 10 is moved to the quarterly heat storage tank 20, and the heat medium requiring heating of the heat storage heat storage compartment 20 is moved to the solar heat collector 10.
급수관(50)은 계간 축열조에서 상대적으로 높은 온도를 가지는 액상 열매체를 흡열/가열 배관부로 공급하기 위한 구성요소이며, 계간 축열 저장조(20)의 상부인 제 1 부(21)와 흡열/가열 배관부(31) 사이에 연결되며 노견(S)에 설치된다. The water supply pipe 50 is a component for supplying a liquid heat medium having a relatively high temperature to the endothermic / heating pipe part in the inter-thermal heat storage tank, and the first part 21 and the endothermic / heating pipe part which is the upper part of the inter-term storage heat storage tank 20. It is connected between the 31 and is installed on the shoulder (S).
회수관(60)은 흡열/가열 배관부(31)에서 노면의 결빙 방지를 위해 에너지를 소모한 냉각된 액상 열매체를 다시 계간 축열조로 공급하기 위한 구성요소로서, 계간 축열 저장조(20)의 하부인 제 2 부(22)와 흡열/가열 배관부(31) 사이를 연결하며, 노견(S)에 설치된다.The recovery pipe 60 is a component for supplying the cooled liquid heat medium that consumed energy again to the quarterly heat storage tank in order to prevent freezing of the road surface in the endothermic / heating pipe part 31, which is a lower portion of the heat storage storage tank 20. It connects between the 2nd part 22 and the endothermic / heating piping part 31, and is installed in the furnace S.
이상과 같은 구성을 가진 본 발명의 일실시예에 따르면, 여름철 태양열을 계간 축열 저장조(20)를 통해 저장한 후, 겨울철에 도로 아래에 기설치된 가열 파이프로 축열 저장조(20)의 액상 열매체를 유동시킴으로써, 겨울철 도로 결빙을 방지하도록 하여 별도의 전기 에너지 공급 없이도 친환경적으로 도로 결빙을 예방할 수 있게 된다. 또한, 본 발명의 일실시예에 따르면, 도로면 아래에 설치된 흡열/가열 배관부의 열매체에 의해 여름철 태양열을 흡열하여 도로면 냉각효과를 가지기 때문에 아스팔트면의 굴곡현상이나 녹아 내림 현상 등의 도로 파괴 현상을 완화시킬 수 있게 된다.According to one embodiment of the present invention having the configuration as described above, after storing the summer solar heat through the quarterly storage heat storage tank 20, the liquid heat medium of the heat storage storage tank 20 flows to the heating pipe pre-installed under the road in winter time By doing so, it is possible to prevent the freezing of the road in winter, and to prevent the freezing of the road in an environmentally friendly manner without a separate electric energy supply. In addition, according to an embodiment of the present invention, because the heat absorbing the summer heat by the heat medium of the heat absorbing / heating pipe portion installed under the road surface has a road surface cooling effect, the road fracture phenomenon such as the curved surface of the asphalt surface or melting phenomenon This can be alleviated.
이하에서는, 급수관(50)과 회수관(60)의 설치 구조에 대하여 도 2를 참조하여 보다 상세하게 설명하도록 한다. Hereinafter, the installation structure of the water supply pipe 50 and the recovery pipe 60 will be described in more detail with reference to FIG. 2.
도 2는 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템 중 급수관(50)과 회수관(60)의 설치 구조를 설명하기 위한 도면이다. 도 2에 도시된 바와 같이, 급수관(50)과 회수관(60)은 노견(S)에 설치되고, 흡열/가열 배관부(31)는 도로면(A)의 아래에 설치되게 된다. 도시된 바와 같이 노견(S)에 급수관(50)과 회수관(60)을 설치하게 되면, 설치후 유지 보수가 편리하게 된다. 도시된 바와 같이, 회수관(60)은 상대적으로 높은 위치에, 급수관(50)은 상대적으로 낮은 위치에 설치된다. 이와 같이 설치하여, 급수관(50)에서 흡열/가열 배관부로 액상 열매체가 이동하는 중의 열손실을 최소화시킬 수 있게 되고, 이에 따라, 도로 결빙 방지 및 해빙 효과가 더욱더 강화될 수 있게 구성된다. 2 is a view for explaining the installation structure of the water supply pipe 50 and the recovery pipe 60 of the road ice prevention system using solar heat, which is an embodiment of the present invention. As shown in FIG. 2, the water supply pipe 50 and the recovery pipe 60 are installed in the furnace S, and the endothermic / heating pipe part 31 is installed below the road surface A. As shown in FIG. As shown, if the water supply pipe 50 and the recovery pipe 60 is installed on the furnace (S), the maintenance after installation is convenient. As shown, the recovery pipe 60 is installed in a relatively high position, the water supply pipe 50 is installed in a relatively low position. By installing in this way, it is possible to minimize the heat loss during the movement of the liquid heat medium from the water supply pipe 50 to the endothermic / heating pipe portion, and thus, the road freeze prevention and thawing effect can be further enhanced.
이하에서는, 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템 중 결빙 방지부(30)의 구조에 대하여 도 3을 참조하여 설명하도록 한다. Hereinafter, the structure of the frost protection unit 30 of the road frost prevention system using solar heat according to an embodiment of the present invention will be described with reference to FIG. 3.
도 3은 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템 중 결빙 방지부(30)의 구조를 설명하기 위한 도면이다. 도 3에 도시된 바와 같이 결빙 방지부(30)는, 제 1 서브 레이어(33), 제 1 메쉬 금속층(34), 흡열/가열 배관부(31), 제 2 메쉬 금속층(35), 제 2 서브 레이어(36)를 포함하여 구성될 수 있다.여기서 아스팔트부(32)는 노면 집열부(A)로서 기능을 할 수 있다. 3 is a view for explaining the structure of the freezing prevention unit 30 of the road freezing prevention system using solar heat, which is an embodiment of the present invention. As illustrated in FIG. 3, the freezing prevention unit 30 may include a first sub layer 33, a first mesh metal layer 34, an endothermic / heating piping unit 31, a second mesh metal layer 35, and a second layer. It may be configured to include a sub-layer 36. Here, the asphalt portion 32 may function as the road surface heat collecting portion (A).
노면 집열부(A)인 아스팔트부(32)의 아래의 제 1 서브 레이어(33)는, 30mm 이상 두께의 콘크리트 또는 모래 하층으로 이루어진다. 이를 통해 도로면의 축열 기능이 강화된다. 즉, 도로면을 향해 조사되는 태양열에 의해 가열된 아스팔트부(32)의 열을 제 1 서브레이어(33)가 흡수하면서 저장하게 된다. The 1st sub-layer 33 under the asphalt part 32 which is the road surface heat collecting part A consists of a concrete or sand underlayer of 30 mm or more thickness. This strengthens the heat storage function of the road surface. That is, the first sublayer 33 stores the heat of the asphalt part 32 heated by the solar heat irradiated toward the road surface while absorbing it.
흡열/가열 배관부(31)를 사이로 제 1 메쉬 금속층(34)과 제 2 메쉬 금속층(35)이 형성된다. 메쉬 금속층(34,35)은 구리 메쉬(bronze mesh)로서, 특히 여름철에 아스팔트부(32)의 태양열이 흡열/가열 배관부(31)로 보다 효과적으로 전달하는 역할을 하며, 겨울철 결빙이 예상되는 경우 흡열/가열 배관부(31)를 통해 공급되는 열매체의 열이 메쉬 금속층(34,35)을 통해 도로면의 상부 및 하부에 전달되도록 하여 아스팔트부(32)의 면을 고르게 가열하도록 한다. 또한, 제 2 서브 레이어(36)에서의 축열이 잘 이루어지도록 하여 도로면 하부 결빙 방지 및 해빙 효과를 강화시키는 기능을 한다. The first mesh metal layer 34 and the second mesh metal layer 35 are formed between the heat absorbing / heating pipe parts 31. The mesh metal layers 34 and 35 are bronze meshes, and in particular, the solar heat of the asphalt 32 is more effectively transmitted to the endothermic / heating pipe 31 during the summer, and the winter is expected to freeze. The heat of the heat medium supplied through the endothermic / heating pipe part 31 is transferred to the upper and lower parts of the road surface through the mesh metal layers 34 and 35 to evenly heat the surface of the asphalt part 32. In addition, the heat storage in the second sub-layer 36 is well performed to prevent the lower road surface freezing and to enhance the thawing effect.
제 2 서브 레이어(36)는, 150~300mm의 자갈층으로서, 흡열/가열 배관부(31)를 통해 공급되는 열을 축열하는 기능을 한다. The second sub-layer 36 is a gravel layer of 150 to 300 mm, and functions to accumulate heat supplied through the endothermic / heating pipe part 31.
이와 같이 제 1 서브 레이어(33)와 제 2 서브 레이어(36)로 축열을 하게 되면, 가열 공급부에 고온의 열매체가 유동하지 않더라도, 이전에 공급된 열을 축열하고 있으므로, 갑작스런 기상 변화에 따른 결빙을 방지하는 효과를 가지게 된다. In this way, when heat is accumulated in the first sub layer 33 and the second sub layer 36, even if a high temperature heat medium does not flow in the heating supply part, the heat supplied to the first sub layer 33 and the second sub layer 36 is accumulated.

이하에서는 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템의 전자적인 동작을 도 4를 참조하여 보다 상세하게 설명하도록 한다. Hereinafter, the electronic operation of the road frost prevention system using solar heat, which is an embodiment of the present invention, will be described in more detail with reference to FIG. 4.
도 4는 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템의 전자적인 동작을 설명하기 위한 블록 구성도이다. 도 4에 도시된 바와 같이, 본 발명의 일실시예인 도로 결빙 방지 시스템은, 순환 펌프(40'), 제 1 온도 센서(90), 제 2 온도 센서(100), 제 3 온도 센서(110), 히트 펌프(120), 그리고, 제어부(130)를 포함하여 구성될 수 있다.4 is a block diagram illustrating an electronic operation of the road frost prevention system using solar heat according to an embodiment of the present invention. As shown in FIG. 4, the road freezing prevention system according to an embodiment of the present invention includes a circulation pump 40 ′, a first temperature sensor 90, a second temperature sensor 100, and a third temperature sensor 110. The heat pump 120 may include a control unit 130.
순환 펌프(40')는 상술한 바와 같이 제 1 순환펌프(40) 및 제 2 순환펌프(45)를 포함하는 개념이다. 제 1 순환 펌프(40)는 계간 축열 저장조(20)와 흡열/가열 배관부(31) 간의 액상 열매체의 유동을 일으키는 구성요소이고, 제 2 순환 펌프(45)는 계간 축열 저장조(20)와 태양열 집열기(10) 간의 액상 열매체의 유동을 일으키는 구성요소이다.The circulation pump 40 'is a concept including the first circulation pump 40 and the second circulation pump 45 as described above. The first circulation pump 40 is a component that causes the flow of the liquid heat medium between the quarterly heat storage reservoir 20 and the endothermic / heating pipe part 31, and the second circulation pump 45 is the quarterly heat storage reservoir 20 and the solar heat. It is a component causing the flow of the liquid heat medium between the collector (10).
제 1 온도 센서(90)는, 상기 도로면 또는 도로면 인근에 설치되어서, 도로면 온도를 측정하는 기능을 하고, 제 2 온도 센서(100)는 계간 축열 저장조(20)에 설치되어서 계간 축열 저장조(20) 내의 열매체의 열저장온도를 측정하는 기능을 하며, 제 3 온도 센서(110)는 상기 태양열 집열기(10)에 의해 가열된 액상 열매체의 집열 온도를 측정하는 기능을 한다.The first temperature sensor 90 is installed on the road surface or in the vicinity of the road surface, and serves to measure the road surface temperature, and the second temperature sensor 100 is installed in the quarterly heat storage tank 20 to store the quarterly heat storage tank. The heat storage temperature of the heat medium in 20 is measured, and the third temperature sensor 110 functions to measure the heat collecting temperature of the liquid heat medium heated by the solar heat collector 10.
그리고 히트 펌프(120)는 급수관(50) 또는 상기 회수관(60) 중 적어도 하나에 설치되어서, 액상 열매체를 추가적으로 가열하는 기능을 한다. 즉, 급수관(50)측에 설치되는 경우, 계간 축열 저장조(20)에 저장되어 있는 축열 액상 열매체의 온도가 결빙 해제를 위해 충분한 온도로 가열되어 있지 않으면, 급수관(50)에 설치된 히트펌프(120)에 의해 결빙 방지부로 공급되는 열매체의 온도를 높혀 결빙 해제 효과를 높일 수 있다. 한편, 회수관(60)을 통해 공급되는 액상 열매체의 온도가 너무 낮은 경우, 계간 축열 저장조(20) 내의 열매체의 온도를 과도하게 낮출 우려가 있으므로, 회수관(60)에 설치된 히트펌프를 동작시켜서 계간 축열 저장조(20)의 액상 열매체의 온도나 낮아지는 것을 방지하기 위하여 회수되는 액상 열매체의 온도를 높여준다.The heat pump 120 is installed in at least one of the water supply pipe 50 and the recovery pipe 60 to further heat the liquid heat medium. That is, when installed on the water supply pipe 50 side, the heat pump 120 provided in the water supply pipe 50, if the temperature of the heat storage liquid heat medium stored in the inter-generation heat storage storage tank 20 is not heated to a temperature sufficient to release the freezing. By increasing the temperature of the heat medium supplied to the freezing prevention unit can be improved the freezing effect. On the other hand, when the temperature of the liquid heat medium supplied through the recovery pipe 60 is too low, there is a risk of excessively lowering the temperature of the heat medium in the inter-generation heat storage storage tank 20, by operating the heat pump installed in the recovery pipe 60 In order to prevent the temperature or the temperature of the liquid heat medium of the heat storage storage tank 20 from decreasing, the temperature of the liquid heat medium recovered is increased.
제어부(130)는, 우선, 제 1 온도 센서(90)와 제 2 온도 센서(100)에서 특정되는 도로면 온도와 열저장 온도를 비교하여 상기 열저장 온도가 상기 도로면 온도보다 소정 온도 이상 낮은 경우, 상기 제 1 순환 펌프(40)를 동작시켜, 상기 도로면에서 조사되는 태양열에 의하여 (10)에 의해 가열된 액상 열매체를 상기 계간 축열 저장조(20)로 공급하도록 한다. 또한, 제어부는, 제 3 온도센서(110)으로부터 획득되는 집열 온도와 열저장온도를 비교하여 열저장온도가 집열 온도보다 소정 온도 이상 낮은 경우, 제 2 순환 펌프(45)를 동작시켜서 가열된 흡열/가열 배관부(21)의 축열 액상 열매체를 계간 축열 저장조(20)에 저장할 수 있게 된다. The controller 130 first compares the road surface temperature and the heat storage temperature specified by the first temperature sensor 90 and the second temperature sensor 100, and the heat storage temperature is lower than the road surface temperature by a predetermined temperature or more. In this case, the first circulation pump 40 is operated to supply the liquid thermal medium heated by 10 by the solar heat radiated from the road surface to the intermittent heat storage storage tank 20. In addition, the control unit compares the heat collecting temperature and the heat storage temperature obtained from the third temperature sensor 110, and when the heat storage temperature is lower than the predetermined temperature by a predetermined temperature or more, the endotherm heated by operating the second circulation pump 45 It is possible to store the heat storage liquid heat medium of the / heating pipe part 21 in the intermittent heat storage storage tank 20.
한편, 상기 회수관(60) 또는 상기 급수관(50)에 설치되어서 공급 온도 또는 회수 온도를 측정하는 제 4 온도 센서(115)가 더 포함될 수 있다. 이에 따라, 제어부(130)는, 회수 온도 또는 공급 온도가 기준온도 이하인 경우, 히트 펌프(120)를 동작시켜서, 상기 회수 온도 및 상기 공급 온도 중 어느 하나가 기준 온도 또는 이하인 경우, 상기 히트 펌프(120)를 동작시켜서 액상 열매체를 가열하도록 할 수 있다.Meanwhile, the fourth temperature sensor 115 may be further installed in the recovery pipe 60 or the water supply pipe 50 to measure a supply temperature or a recovery temperature. Accordingly, the control unit 130 operates the heat pump 120 when the recovery temperature or the supply temperature is equal to or lower than the reference temperature, and when the one of the recovery temperature and the supply temperature is equal to or lower than the reference temperature, the heat pump ( 120 may be operated to heat the liquid heat medium.
이하에서는 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템에 사용되는 계간 축열 저장조(20)에 대하여 도 5를 참조하여 보다 상세하게 설명하도록 한다. Hereinafter, with reference to Figure 5 with respect to the inter-generation heat storage reservoir 20 used in the road ice prevention system using solar heat of an embodiment of the present invention will be described in more detail.
도 5는 본 발명의 일실시예인 태양열을 이용한 도로 결빙 방지시스템에 사용되는 계간 축열 저장조(20)의 구조를 설명하기 위한 개념 분해 사시도이다,5 is a conceptual exploded perspective view for explaining the structure of the quarterly heat storage reservoir 20 used in the road ice prevention system using solar heat, which is an embodiment of the present invention,
도 5에 도시된 바와 같이, 계간 축열 저장조(20)의 내부를 보면, 중앙부에 수평으로 설치되는 다공판(70)이 있다. 이 다공판(70)을 기준으로, 상부를 제 1 부(21)라 하고, 하부를 제 2 부(22)라 한다. 제 1 부(21)에는 급수관(50)이 연결되고, 제 2 부에는 회수관(60)이 연결된다. 액체의 성질상 상대적으로 높은 온도의 액상 열매체는 제 1 부(21)에 위치하게 되고, 상대적으로 낮은 온도의 액상 열매체는 제 2 부(22) 에 위치하게 된다. As shown in FIG. 5, when looking at the interior of the quarterly heat storage reservoir 20, there is a porous plate 70 installed horizontally in the center portion. Based on this porous plate 70, the upper part is called the 1st part 21 and the lower part is called the 2nd part 22. As shown in FIG. The water supply pipe 50 is connected to the first part 21, and the recovery pipe 60 is connected to the second part. Due to the nature of the liquid, the relatively high temperature liquid heat medium is located in the first part 21, the relatively low temperature liquid heat medium is located in the second part 22.
제 1 부(21)와 제 2 부(22)를 구분하는 다공판(70)은, 제 1 부(21)와 제 2 부(22)를 구분하는 기준이 되며, 제 2 부(22)에 있는 상대적으로 온도가 낮은 열매체가 자유롭게 제 1 부(21)로 대류하는 것을 방해하여서 제 1 부(21)의 액상 열매체가 상대적으로 좀더 높은 온도를 유지하도록 한다. 이와 더불어서 다공판(70) 위에는 다수의 구형 축열재(80)가 위치하게 된다. 이에 따라 제 2 부에 위치하는 열매체가 제 1 부(21)로 이동하는것이 제한되게 된다. The porous plate 70 that distinguishes the first part 21 and the second part 22 serves as a reference for distinguishing the first part 21 and the second part 22. The relatively low temperature heat medium, which is free to convection freely into the first part 21, causes the liquid heat medium of the first part 21 to maintain a relatively higher temperature. In addition, a plurality of spherical heat storage material 80 is positioned on the porous plate 70. Accordingly, the movement of the heat medium located in the second part to the first part 21 is restricted.
