Description

진공관을 이용한 태양열 집열기 일체형 태양열 온수기{A Water Heating Apparatus Unified with Solar Heat Collector Using Vaccum Pipe}Solar Water Heater Integrated Vacuum Heater using Vacuum Tube {A Water Heating Apparatus Unified with Solar Heat Collector Using Vaccum Pipe}

본 발명은 진공관을 이용한 태양열 집열기 일체형 태양열 온수기에 관한 것으로서, 보다 상세하게는 이중진공관 타입의 태양열 집열기와 축열탱크를 일체로 결합 되도록 설치하여, 집열기와 축열탱크를 연결하는 별도의 배관이 필요 없으며, 대상물에 공급될 물을 직접 집열기에 급수하여 데울 수 있는 장치에 관한 것이다.The present invention relates to a solar heat collector-integrated solar water heater using a vacuum tube, and more specifically, to install a double vacuum tube type solar collector and a heat storage tank integrally, there is no need for a separate pipe connecting the heat collector and the heat storage tank, The present invention relates to a device for heating water supplied to an object by directly supplying it to a collector.

태양열이용시스템이란 태양광선의 파동성질과 광열학적성질을 이용하여 태양열 흡수, 저장, 열변환을 통하여 건물의 냉난방 및 급탕 등에 활용하는 기술이며, 크게 집열부, 축열부, 이용부로 구성되어 있다The solar heat utilization system is a technology used for cooling and heating and hot water supply of buildings by absorbing, storing, and converting solar heat using wave characteristics and photothermal properties of solar rays.

집열부는 태양의 복사에너지를 흡수하여 재생가능한 열에너지로 변환시키는 기기로 중요한 역할을 담당하고 있으며, 일반적으로 태양열 집열기는 집광식과 비집광식이 있다.The heat collecting unit plays an important role as a device for absorbing the sun's radiant energy and converting it into renewable heat energy. Generally, the solar heat collecting unit has a condensing type and a non-condensing type.

집광식의 경우에는 200℃이상의 고온열을 얻을 수 있으나, 태양추적시스템을 구비해야 하는 등 초기 설치비 및 관리비가 많이 들어 주로 태양열 발전에 쓰인다. In the case of condensing type, high temperature heat of 200 ℃ or more can be obtained, but it is mainly used for solar power generation because it requires a lot of initial installation and management costs such as having to provide a solar tracking system.

비집광식은 평판형과 진공관형으로 나뉘는데, 종래의 평판형 태양열 집열기는 도 1에서 나타낸 바와 같이 금속제 태양열 집열판(130)에 가열관(140)이 설치되어 있는 것으로, 태양으로부터 발산된 태양열이 집열판(130)에 집열되면 집열판에 설치된 가열관(140)의 내부에 있는 열매체가 가열되고, 가열된 열매체는 밀도차에 의해 열매체 유입관(110)을 통해 축열탱크(100)로 유입된다. 유입된 열매체는 축열탱크(100)내에서 냉수와 상호열교환을 통해 온도가 감소하고 온도가 감소된 열매체는 다시 열매체 환수관(120)을 통해 가열관(140)으로 돌아오게 된다. 자연순환방식이라고 한다.The non-condensing type is divided into a flat plate type and a vacuum tube type. In the conventional flat plate type solar collector, as shown in FIG. 1, the heating tube 140 is installed in the metal solar heat collecting plate 130, and the solar heat emitted from the sun is collected. When the heat collector 130 is collected, the heat medium inside the heating tube 140 installed on the heat collecting plate is heated, and the heated heat medium flows into the heat storage tank 100 through the heat medium inlet pipe 110 by the density difference. The heat medium introduced into the heat storage tank 100 is reduced in temperature through mutual heat exchange with cold water, and the heat medium whose temperature is reduced is returned to the heating tube 140 through the heat medium return pipe 120. It is called natural circulation.

이러한 태양열 온수 급탕 시스템에 사용되는 기본적인 태양열 집열기로서 가격이 저렴할 뿐 아니라 열매체가 자연순환되어 가장 효율적인 집열기로 알려져 있으나, 열매체에 의한 열 취득 온도는 80℃이하로 비교적 낮아 사용이 제한되고 있다.The basic solar collector used in such a solar hot water hot water supply system is not only inexpensive but also known as the most efficient collector due to the natural circulation of the heat medium.

종래의 진공관형 태양열 집열기는 도 2에서 나타낸 바와 같이 하방이 밀폐된 진공 유리관(210) 내에 열전달 플레이트와 U자형의 가열관(220)이 설치되어 있는 것으로 열매체에 의한 열 취득 온도는 80℃~200℃의 범위 내로 종래의 평판형 태양열 집열기 보다 고온의 열을 취득할 수 있으나, 열매체가 자연순환되지 않으므로 별도의 열매체 순환펌프(200)가 필요하여 효율성이 떨어진다는 단점이 있다. In the conventional vacuum tube solar collector, as shown in FIG. 2, the heat transfer plate and the U-shaped heating tube 220 are installed in the vacuum glass tube 210 sealed downward, and the heat acquisition temperature by the heat medium is 80 ° C. to 200 ° C. FIG. It is possible to obtain heat at a higher temperature than the conventional flat solar collector in the range of ℃, but since the heat medium is not naturally circulated, a separate heat medium circulation pump 200 is required and the efficiency is low.

집열기 타입에 따른 장단점과는 별개로, 도 1 및 도 2에 개시된 종래 태양열 집열기는 가열된 열매체를 축열탱크로 보내고, 차가워진 열매체를 환수하기 위한 배관들이 필요하고 그에 따라 설치 공간이 커지고 제작비용이 높은 단점이 있다.Apart from the advantages and disadvantages of the collector type, the conventional solar collectors disclosed in FIGS. 1 and 2 require piping to send the heated heating medium to the heat storage tank, and to return the cooled heating medium, thereby increasing the installation space and manufacturing cost. There is a high disadvantage.

도 6은 본 발명의 제 3 실시예에 따른 진공관을 이용한 태양열 집열기 일체형 태양열 온수기의 구조를 도시한 단면도이다.6 is a cross-sectional view showing the structure of a solar collector-integrated solar water heater using a vacuum tube according to a third embodiment of the present invention.

제 3 실시예는 급수관(20)과 출수관(21) 간에 체크 밸브(V)와 펌프(P)가 추가적으로 설치되어 있는 것이 특징적인 구성으로서, 온수를 사용하지 않는 동안, 즉, 급수관(20)으로의 물의 유입과 출수관(21)으로부터의 온수의 유출이 없는 경우에 탱크 내부의 물이 내부 유로를 따라 순환하도록 하는 것이 특징적이다. The third embodiment is characterized in that the check valve (V) and the pump (P) is additionally installed between the water supply pipe (20) and the water discharge pipe (21), while not using hot water, that is, the water supply pipe (20) When there is no inflow of water into and outflow of hot water from the outlet pipe 21, the water inside the tank is circulated along the inner flow path.

체크 밸브(V)는 급수관(20)으로부터 출수관(21)으로의 물이 역류하는 것을 방지하는 것이고, 펌프(P)는 가열관(30)에 머무르고 있는 물이 열교환관(40)을 따라 순환하도록 하는 기능을 수행한다.The check valve V prevents the backflow of water from the water supply pipe 20 to the water outlet pipe 21, and the pump P circulates along the heat exchange pipe 40 with the water remaining in the heating pipe 30. Perform the function to make it work.

온수를 사용하고 있지 않은 동안에는 가열된 온수가 외부로 유출되지 않으므로 지속적으로 태양열을 받는 가열관(30) 내에 위치한 물의 온도가 열교환관(40) 내의 물의 온도 또는 축열탱크(10) 내의 열매체(80)의 온도보다 높게 된다. 따라서, 이러한 경우 펌프(P)의 구동에 의해 물을 순환시켜 가열관(30)측의 고온의 물이 열교환관(40)을 통과하면서 축열탱크(10) 내의 열매체(80)와 열교환하여 열매체(80)의 온도를 높여줌으로써 열효율을 증가시키게 된다.Since the heated hot water does not flow to the outside while the hot water is not used, the temperature of the water located in the heating tube 30 continuously receiving solar heat is the temperature of the water in the heat exchange tube 40 or the heat medium 80 in the heat storage tank 10. It is higher than the temperature of. Therefore, in this case, the water is circulated by the driving of the pump P so that the hot water of the heating tube 30 passes through the heat exchange tube 40 and heat-exchanges with the heat medium 80 in the heat storage tank 10 to heat the heat medium ( Increasing the temperature of 80 will increase the thermal efficiency.

온수 사용중에는 펌프(P)가 동작하지 않으므로 가열관(30)과 열교환관(40)을 통해 가열된 온수가 출수관(21)을 통해 외부로 공급된다.Since the pump P does not operate while the hot water is in use, the hot water heated through the heating tube 30 and the heat exchange tube 40 is supplied to the outside through the water outlet tube 21.
