본 발명은 태양열 난방장치의 집열기로부터 태양열을 흡수한 열전달유체의 열을 저장하는 열저장탱크에서 효과적으로 열을 발열 시스템으로 방출하도록 하는 효과적으로 열을 저장하고 열저장탱크의 열교환 시스템 구조에 관한 것니다.The present invention relates to a heat exchange system structure of a heat storage tank that effectively stores heat to effectively release heat to a heat generating system in a heat storage tank that stores heat of a heat transfer fluid absorbing solar heat from a collector of a solar heating device.

오늘날 화석 연료 자원이 고갈되어 태양열 에너지는 많은 대체 에너지원중에서 가장 잘 알려져 있는데, 현재 화석연료가 인류 사용 에너지의 95%를 차지하고 있는 현실에 비추어 볼 때 화석 연료자원 고갈에 따른 대체 에너지로서 이 태양열 에너지는 작금에 있어 각광을 받는 에너지원이다.Today, solar energy is best known among many alternative energy sources due to the depletion of fossil fuel resources, and in the light of the fact that fossil fuels currently make up 95% of human energy, solar energy is an alternative to fossil fuel resource depletion. Is the energy source that is in the spotlight in recent years.

따라서 현재 태양열 에너지를 이용하여 가옥 또는 온실의 실내온도를 높이거나 물을 데우는 태양에너지 시스템이 개발되고 있는데 특히 태양 에너지를 저장하는 연구와 개발이 경주되고 있다.Therefore, a solar energy system is being developed that uses solar energy to raise the indoor temperature of a house or greenhouse or heat water. Especially, research and development for storing solar energy are underway.

태양 난방장치의 개략적 구성도를 제1도에 도시하였는데 태양난방장치를 구성하는 장치는 태양복사 에너지를 모으는 집열기(1)와 집열기(1)로부터 모아진 열에너지를 저장하는 열저장탱크(2) 그리고 열저장탱크(2)내에 저장된 열에너지를 필요한만큼 빼내어 실내 온도를 덮히거나 온수사용에 사용하는 방열시스템(3)으로 구성된다.The schematic diagram of the solar heating system is shown in FIG. 1. The solar heating system is composed of a collector (1) for collecting solar radiation energy, a heat storage tank (2) for storing thermal energy collected from the collector (1), and heat. It is composed of a heat dissipation system (3) to extract the heat energy stored in the storage tank (2) as necessary to cover the room temperature or to use hot water.

상기 집열기(1)는 집중 반사경을 이용한 집열기와 평편한 흑체금속판을 사용한 집열기가 있는데, 상기 집중반사경 집열기는 직접 조사되는 태양광만을 이용하고 태양고도에 따라 회전하는 기계장치가 설치되고, 상기 흑체금속판 집열기는 구름 등에 의해 산란된 태양광도 사용하기에 이런 유형의 집열기는 항상 태양을 향할 필요가 없어 보통 흑체금속판 집열기는 계절의 낮 시간에 최대한 일사(日射)를 받을 수 있는 방위에 놓는다.The collector 1 has a collector using a concentrated reflector and a collector using a flat black body metal plate, and the concentrated reflector collector uses only solar light that is directly irradiated and is equipped with a mechanism that rotates according to the altitude of the black body metal plate. Since collectors also use sunlight scattered by clouds, these types of collectors do not always have to face the sun, so black collectors are usually placed in a position that allows them to receive maximum solar radiation during the daytime of the season.

이와같은 흑체금속판을 사용한 집열기는 방위에 관계없는 특성 때문에 주택용, 상업용 난방장치로 가장 바람직하고 많이 이용되고 있다.The collector using such a black body metal plate is most preferred and widely used as a heating device for homes and commercials because of its unrelated orientation.

이와같은 집열기(1)에서 집중반사경 또는 흑체금속판에 의해 태양광의 빛에너지를 열에너지로 변화시키면 이 열에너지를 구리관을 이용하여 열전달 유체에 전달시켜 열저장탱크(2)에 열을 저장하도록 하는 것이다.When the light energy of solar light is changed into heat energy by the concentrated reflector or the black body metal plate in the collector 1, the heat energy is transferred to the heat transfer fluid using a copper pipe to store heat in the heat storage tank 2.

상기 열저장탱크(2)는 밤이나 흐린날을 위하여 맑은날에 모아둔 열을 저장하는 장소로서 지상 또는 지하에 설치되는 것으로 탱크내에 물, 암석, 소금 또는 특수용액을 충진시켜 여기에 열을 저장하도록 한 것으로 열저장탱크(2)의 크기는 그 지역의 기후 조건에 따라 달라진다.The heat storage tank (2) is a place for storing heat collected on a clear day for a night or cloudy day to be installed on the ground or underground to fill the tank with water, rock, salt or special solution to store heat therein. The size of the heat storage tank 2 depends on the climatic conditions of the area.

그리고 상기 집열기(1)내의 열전도를 위한 열전도유체와 열저장탱크(2)내의 열저장유체를 동일한 유체를 사용한 경우 일반적으로 열교환기(21)가 설치되어, 방열시스템(3)에 사용되는 물을 데우는데 사용되고 있다.In the case where the same fluid is used for the heat conduction fluid for heat conduction in the collector 1 and the heat storage fluid in the heat storage tank 2, a heat exchanger 21 is generally installed to provide water used for the heat dissipation system 3. It is used to warm up.

상기 열전달유체는 집열기(1) 또는 열저장탱크(2)에서 사용되는 열 전달매개물로서 집열기(1)에 설치된 동파이프나 열저장탱크(2) 및 탱크내에 설치된 열교환기를 구성하는 금속을 부식하지 않아야 하고 안정되고 안전하며 저가이어야 한다.The heat transfer fluid is a heat transfer medium used in the collector 1 or the heat storage tank 2 and should not corrode the metal constituting the copper pipe installed in the collector 1 or the heat storage tank 2 and the heat exchanger installed in the tank. It should be stable, safe and inexpensive.

상기 열저장탱크(2)의 열교환기(21)는 출열식 열교환기와 저탕식 열교환기로 대별되는에, 제2도에 상기 저탕식 열교환기(가)와 축열식 열교환기(나)를 개략적으로 단면도로 도시하고 있다.The heat exchanger 21 of the heat storage tank 2 is roughly divided into a heat exchanger type and a heat exchanger type heat exchanger. In FIG. 2, the heat exchanger type heat exchanger (A) and the heat storage type heat exchanger (I) are schematically illustrated in cross section. It is shown.

상기 저탕식 열교환기는 제2a도에 도시한바와 같이 집열기(1)로부터 태양열을 흡수하여 열저장탱크(2)에서 열교환을 하는 열전달 유체가 흐르는 열전달유체파이프(2P)가 열전달탱크(2)내에 바닥면측에 집중적으로 깔리어 탱크내(2)에 저장된 냉수에 열전달하도록 한 것이고, 축열식 열교환기(나)의 경우는 제2b도와 같이 상기 열전달유체파이프(2P)가 하나의 파이프 몸체로 이루어져 이 파이프가 코일상으로 절곡되어 열교환기(2) 탱크내에 설치한 것이다.As shown in FIG. 2A, the low-heat type heat exchanger absorbs solar heat from the collector 1 and a heat transfer fluid pipe 2P through which a heat transfer fluid for heat exchange in the heat storage tank 2 flows is bottomed in the heat transfer tank 2. The heat transfer to the cold water stored in the tank (2) concentrated on the surface side, in the case of the heat storage heat exchanger (b), the heat transfer fluid pipe (2P) consists of a single pipe body as shown in 2b It is bent in a coil and installed in the tank of the heat exchanger (2).

그런데 저탕식 열료환방법에 비하여 축열식 열교환방법의 열교환 능률이 높아 선호된다.However, the heat exchange efficiency of the heat storage heat exchange method is preferred as compared to the low heat type heat exchange method.

그러나 상기와 같은 종래의 축열식 열교환방법은 하나의 공간으로된 탱크내에 코일상의 파이프가 설치되어 있기에 열교환 능률이 떨어질 수 밖에 없었다.However, in the conventional heat storage heat exchange method as described above, the heat exchange efficiency is inevitably deteriorated because the pipe on the coil is installed in the tank consisting of one space.

예를들어 코일상 파이프(2P)에 방열시스템(3) 및 급수원과 연결하여 물(W)이 흐르도록 하고 열저장탱크(2)내에 열전달유체(L)가 흐르도록 할 때(반대로 코일상 파이프에 열전달유체가 흐르도록 하고 열저장탱크내에 물이 흐르도록 할 수도 있음) 집열기(1)로부터 태양열을 흡수하여 고온상태의 열전달유체(L)가 열저장탱크(2)내로 들어와 코일상파이프(2P)에 흐르는 물(W)을 데워 방열시스템에서 그 열을 이용하도록 하게 되는데 열전달유체(L)와 물(W) 사이의 열교환율은 유체(L,W)의 흐름유속과 접촉면적에 의존하는데 상기와 같은 종래의 열저장탱크의 열교환시스템 구조에서는 열교환 능률이 낮았던 문제점이 있었다.For example, when the water (W) flows and the heat transfer fluid (L) flows in the heat storage tank (2) by connecting the heat pipe (2P) to the heat dissipation system (3) and the water supply source. The heat transfer fluid may flow in the pipe and water may flow in the heat storage tank.) The heat transfer fluid L of the high temperature state is absorbed into the heat storage tank 2 by absorbing solar heat from the collector 1 and the coiled pipe ( The water (W) flowing through 2P) is used to heat the heat dissipation system. The heat exchange rate between the heat transfer fluid (L) and the water (W) depends on the flow velocity and the contact area of the fluid (L, W). The heat exchange system structure of the conventional heat storage tank as described above has a problem that the heat exchange efficiency is low.

이와 같은 종래의 열저장탱크에 있어 열교환시스템 구조의 문제점을 해결하기 위하여 본 발명이 창안되었는데 본 발명의 목적은 열저장탱크의 열교환시스템 구조를 변경하여 열전달유체(L)와 물(W)사이의 열교환을 3단계로 나누어 단계적으로 열교환이 일어나도록 하므로서 열교환 능률을 배가하도록 하는데 있다.In order to solve the problem of the heat exchange system structure in the conventional heat storage tank as described above, an object of the present invention is to change the heat exchange system structure of the heat storage tank to the heat transfer fluid (L) and the water (W) between The heat exchange is divided into three stages so that the heat exchange takes place step by step to double the heat exchange efficiency.

이하, 첨부도면과 함께 본 발명에 따른 열교환시스템 구조에 대하여 상세하게 설명하기로 한다.Hereinafter, the heat exchange system structure according to the present invention together with the accompanying drawings will be described in detail.

제3도는 본 발명에 따른 열교관시스템을 구현한 열저장탱크의 횡단면도인데, 제3도에 도시된바처럼 본 발명에 따른 열교환시스템은 열저장탱크(2)내부를 2개의 경판(21,21')에 의해 3개의 격리된 공간을 형성하여 좌측부터 1차열 교환공간(S1), 2차열교환공간(S2), 3차열교환공간(S3)으로 구획지우고 파이프를 내설하는데 제3도에 도시된 본 발명의 일실시예에 있어서는 방열시스템과 급수원에 연결되어 열전달유체에 의해 열을 흡수하는 물(W)이 흐르는 수도관부(200)와 집열기(1)로부터 태양열을 흡수하여 열저장탱크(2)로 열을 운반하는 열전달유체를 유입시키고 다시 집열기(1)로 방출시키는 열전달유체 유입파이프(IP)와 열전달유체 유출파이프(OP)가 내설된다.3 is a cross-sectional view of a heat storage tank implementing the heat pipe system according to the present invention. As shown in FIG. 3, the heat exchange system according to the present invention includes two hard plates 21 and 21 inside the heat storage tank 2. The three isolated spaces are formed by '), and are divided into the primary heat exchange space (S1), the secondary heat exchange space (S2) and the tertiary heat exchange space (S3) from the left side, and the pipes are installed. In one embodiment of the present invention is connected to the heat dissipation system and the water supply source to absorb the heat from the water pipe unit 200 and the collector (1) flowing the water (W) flowing by the heat transfer fluid heat storage tank (2) The heat transfer fluid inflow pipe (IP) and the heat transfer fluid outlet pipe (OP) are introduced to the heat transfer fluid carrying heat to the heat discharger and discharged back to the collector 1.

상기 수도관부(200)는 냉수유입파이프(200C), 열교환파이프(200E) 그리고 온수유출파이프(200H)로 구성되는데, 상기 온수유출파이프(200H)는 열저장탱크(2)의 일측면과 2개의 경판(21,21')을 관통하여 1차열교환공간(S1), 2차열교환공간(S2)을 거쳐 그 자유단부가 3차열교환공간 상부측에 위치되도록 형성되고, 타측단부는 방열시스템과 연결되고, 상기 열교환파이프(200E)는 코일상으로 절곡되어 2차열교환공간(S2)내에 형성되고 그 일측자유단부인 유입구(200E)는 1차열교환공간(S1)내에 형성되며 타측 자유단부인 유출구(200E2)는 3차열교환공간(S3)내에 형성된다.The water pipe part 200 is composed of cold water inlet pipe (200C), heat exchange pipe (200E) and hot water outlet pipe (200H), the hot water outlet pipe (200H) is one side and two sides of the heat storage tank (2). It is formed so that the free end is located in the upper side of the third heat exchange space through the primary heat exchange space (S1), the second heat exchange space (S2) through the hard plates (21, 21 '), and the other end is connected to the heat dissipation system.

그리고 상기 열교환파이프(200E)는 코일상으로 절곡된 열교환파이프(200E)의 하부측에 연결되어 경판(21)을 관통하면서 파이프가 절곡되어 제3도에 도시된바처럼 1차열교환공간의 상부측에 형성되어 있고, 열교환파이프(200E)의 유출구(200E2)는 코일상으로 절곡된 열교환파이프(200E)의 상부측에서 연결되면서 경판(21')을 관통하여 파이프가 절곡되면서 3차열교환공간(S3)의 하부측에 형성된다.The heat exchange pipe 200E is connected to the lower side of the heat exchange pipe 200E bent in a coil shape, and the pipe is bent while penetrating the hard plate 21, as shown in FIG. 3, and the upper side of the primary heat exchange space. And the outlet 200E2 of the heat exchange pipe 200E is connected to the upper side of the heat exchange pipe 200E bent into a coil while passing through the hard plate 21 'to bend the pipe to form a third heat exchange space S3. Is formed on the lower side.

상기 냉수유입파이프(200C)는 제3도에 도시된바처럼 1차열교환공간(S1)이 형성된 열저장탱크(2) 의 측면하단부측을 관통시켜 1차열교환공간(S1)과 급수원을 연결하도록 하고 있다.As shown in FIG. 3, the cold water inflow pipe 200C connects the primary heat exchange space S1 and the water supply source by passing through the lower side of the side surface of the heat storage tank 2 in which the primary heat exchange space S1 is formed. I'm trying to.

상기 열전달유체 유입파이프(IP)는 제3도에 도시된바처럼 열저장탱크(2)의 일측면을 관통하여 1차열교환공간(S1)을 거쳐 2차열교환공간(S2)에 자유단부가 노출되도록 하고 타측은 집열기(1)와 연결되어 있으며, 상기 열전달유체 유출파이프(OP)는상기 열전달유체 유입파이프(IP)가 형성된 측의 반대측 열저장탱크 측면을 관통하여 3차열교환공간(S3)을 거쳐 2차열교환공간(S2)에 자유단부가 노출되도록 하고 타측은 집열기(1)와 연결되어 형성되는 것이다.The heat transfer fluid inflow pipe (IP) passes through one side of the heat storage tank (2) as shown in FIG. 3 and passes through the primary heat exchange space (S1) to expose the free end to the secondary heat exchange space (S2).

이상과 같은 구성으로 이루어진 본 발명에 따른 열교환시스템 구조를 갖는 축열식 열저장 탱크에 있어 열전달유체(L)와 물(W)간의 열교환거동들 살펴보면, 먼저 집열기(1)로부터 태양열을 흡수한 열전달유체(L)가 유입파이프(IP)를 통해 열저장탱크(2)의 2차열전달교환공간(S2)내로 유입 충진되어 2차열교환공간(S2)에 설치된 수로관부(200)의 열교환파이프(200E)내를 흐르는 냉수(W)를 데우게 되는 것이며, 이와같이 수로관부(200)의 열교환파이프(200E)내를 흐르는 냉수(W')에 열을 전달하고 냉각된 열전달유체(L')는 열전달유체 유출파이프(OP)를 통해 다시 집열기(1)로 이송되어 태양열을 흡수하게 되는 것이다.Looking at the heat exchange behavior between the heat transfer fluid (L) and the water (W) in the heat storage tank having a heat exchange system structure according to the present invention configured as described above, first the heat transfer fluid absorbed solar heat from the collector (1) ( L) is introduced and filled into the secondary heat transfer exchange space (S2) of the heat storage tank (2) through the inlet pipe (IP) and in the heat exchange pipe (200E) of the water pipe part 200 installed in the secondary heat exchange space (S2).

그리고 수로관부(200)를 흐르는 물(W)은 급수원으로부터 냉수유입파이프(200C)을 통해 1차열교환공간(S1)의 하부측으로 진입되어 2차열교환공간(S2) dp충진된 열전달유체(L)의 열을 경판(21)을 통하여 간접적으로 전달받으며 점차 상승하여 열교환파이프(200E1)의 유입구(200E1) 를 통하여 1차열교환공간(S1) 에서 데워진 물(W)이 2차열교환공간(S2)에 형성된 열교환파이프(200E)로 진입되어 여기에서 2차로 열교환이 이루어지며 유출구(200E2)를 통해 3차열교환공간(S3)내로 진입되고 여기에서 경판(21')을 통해 보온되다가 온수유출파이프(200H)를 통하여 데워진 물(W)은 방열시스템으로 이동되어 결국 사용되는 것이다.Then, the water (W) flowing through the water pipe part 200 enters the lower side of the primary heat exchange space (S1) through the cold water inlet pipe (200C) from the water supply source, and the heat transfer fluid (L) filled with the secondary heat exchange space (S2) dp. ) Is indirectly transmitted through the plate 21 and gradually rises so that the water (W) warmed in the primary heat exchange space (S1) through the inlet (200E1) of the heat exchange pipe (200E1) is the secondary heat exchange space (S2). Entered into the heat exchange pipe (200E) formed in the second heat exchange is made here and enters into the third heat exchange space (S3) through the outlet (200E2), where it is warmed through the hard plate 21 'and the hot water discharge pipe (200H) The water (W) warmed through) is transferred to the heat dissipation system and eventually used.

이와같은 열전달유체(L)와 물(W)의 이동은 각각의 온도차에 기인한 물의 대류현상에 기인하여 자연적으로 이루어지게 되어 있으며, 상기된 본 발명에 따른 열교환시스템 구조를 구현한 열저장탱크의 실시예에 있어 열전달유체(L)와 물(W)을 상호 바꾸어 2차열교환공간(S2)에 열전달유체(L)를 흐르게 할 수 있을 것이다.The heat transfer fluid (L) and the water (W) is moved naturally due to the convection of the water due to the temperature difference, the heat storage tank of the heat storage system according to the present invention described above In an embodiment, the heat transfer fluid L and the water W may be interchanged to allow the heat transfer fluid L to flow in the secondary heat exchange space S2.

이와같은 구성 및 작용으로 이루어진 본 발명에 따른 열저장탱크에 있어 열교환시스템 구조는 상기된바처럼 열저장탱크(2)를 2개의 경판에 의하여 1차열교환공간, 2차열교환공간, 3차열교환공간으로 구획지어 물과 열전달유체간의 열교환이 3차에 걸쳐 이루어지므로서 열교환 능률이 종래에 비하여 극히 향상되었다 할 것이다.In the heat storage tank according to the present invention made of such a configuration and action, the heat exchange system structure is the heat storage tank 2 as described above by means of two hard plates primary heat exchange space, secondary heat exchange space, tertiary heat exchange space As the heat exchange between the water and the heat transfer fluid is carried out in three stages, the heat exchange efficiency is greatly improved compared to the conventional one.
