태양열을 이용한 난방 및 온수장치{HEATING APPARATUS USING SOLAR HEAT}Solar heating and hot water device {HEATING APPARATUS USING SOLAR HEAT}

본 발명은 태양열을 이용한 난방 및 온수장치에 관한 것으로서, 더욱 상세하게는 축열탱크 내부에서의 상하 온도차를 상쇄시키기 위한 온도평형수단을 포함하는 태양열을 이용한 난방 및 온수장치에 관한 것이다.The present invention relates to a heating and hot water device using solar, and more particularly, to a heating and hot water device using solar heat including a temperature balance means for offsetting the temperature difference between the upper and lower sides in the heat storage tank.

일반적으로 태양열에 의해 열교환매체를 가열하고, 이를 이용하여 난방하는 태양열을 이용한 난방 및 온수장치는 태양열을 집열하는 집열판과, 집열판에 의해 집열된 태양열로 가열되는 열교환매체가 지나는 집열관과, 열교환매체와 열교환되어 가열되는 난방용수가 저장된 축열탱크로 이루어져 있다.In general, a heating and hot water device using solar heat that heats a heat exchange medium by solar heat and heats the heat exchange medium includes a heat collecting plate for collecting solar heat, a heat collecting tube through which a heat exchange medium heated by solar heat collected by the heat collecting plate passes, and a heat exchanger. It consists of a heat storage tank in which heating water which is heated by heat exchange with the medium is stored.

그리고 난방용수를 난방하고자 하는 지역에 순환시켜 난방하기 위한 순환펌프 및 난방순환관로가 구비된다.A circulation pump and a heating circulation pipe are provided for circulating and heating the heating water in an area to be heated.

이러한 태양열을 이용한 난방 및 온수장치의 종래기술로는 대한민국 등록특허공보 제0272932호, 대한민국 등록실용신안공보 제0204297호, 대한민국 등록실용신안공보 제0370042호등에 개시되어 있다.Conventional technologies for heating and hot water devices using such solar heat are disclosed in Korean Patent Registration No. 002732, Republic of Korea Utility Model Registration No. 0242428, and Korean Utility Model Registration No. 0370042.

그러나 종래기술의 태양열을 이용한 난방 및 온수장치에서는 태양열에 의해 가열되는 열교환매체를 저장하는 축열탱크 내에서의 상하 온도편차가 발생하는 문 제점이 있었다.However, in the prior art solar heating and hot water apparatus, there is a problem that the vertical temperature difference in the heat storage tank for storing the heat exchange medium heated by the solar heat occurs.

There is a problem.

이하, 첨부된 도면을 참조하여 본 발명에 따른 태양열을 이용한 난방 및 온수장치를 더욱 상세하게 설명하면 다음과 같다.Hereinafter, a heating and hot water device using solar heat according to the present invention with reference to the accompanying drawings in more detail.

도 1에는 본 발명에 따른 태양열을 이용한 난방 및 온수장치(100)의 제1 실시예가 도시되어 있다.1 shows a first embodiment of a heating and hot water device 100 using solar heat according to the present invention.

도면을 참조하면, 본 실시예의 태양열을 이용한 난방 및 온수장치(100)는 태양열을 집열하여 열교환매체를 가열하는 집열유닛(110)과, 난방용수가 저수되는 축 열탱크(120)와, 집열유닛(110)과 축열탱크(120)를 연결하는 열교환관(112)과, 축열탱크(120) 내에서의 난방용수의 온도편차를 제거하기 위한 온도편차 제거수단(150)을 포함한다.Referring to the drawings, the heating and hot water device 100 using solar heat of the present embodiment is a heat collecting unit 110 for collecting heat to heat the heat exchange medium, the heat storage tank 120, the heating water is stored, and a heat collecting unit ( A heat exchange tube 112 connecting the heat storage tank 120 and the heat storage tank 120 and a temperature deviation removing means 150 for removing the temperature deviation of the heating water in the heat storage tank 120.

집열유닛(110)은 태양열을 집열할 수 있는 집열기(111)로 되어 있으며, 도시되지는 않았으나, 집열기(111)의 내부에는 열교환매체가 이동하면서 태양열에 의해 가열될 수 있도록 가열관이 마련되어 있다. 따라서 집열기(111)의 일측을 통해 집열기(111) 내로 유입된 열교환매체는 가열관을 통해 집열기(111)의 내부를 통과하는 과정에서 태양열에 의해 가열된 후 토출된다.The heat collecting unit 110 is a heat collector 111 capable of collecting solar heat, and although not shown, a heat pipe is provided inside the heat collector 111 so as to be heated by solar heat while the heat exchange medium is moved. Therefore, the heat exchange medium introduced into the collector 111 through one side of the collector 111 is heated by solar heat in the process of passing through the inside of the collector 111 through a heating tube and then discharged.

집열기(111)로부터 토출된 열교환매체는 열교환관(112)을 따라 이동하는데, 열교환관(112)은 일측단부가 상기 집열기(111)의 출구에 연결되고 타측 단부가 집열기(111)의 입구에 연결되어 있어서 열교환매체가 순환하는 폐회로를 형성하게 된다.The heat exchange medium discharged from the collector 111 moves along the heat exchange tube 112. The heat exchange tube 112 has one end connected to the outlet of the collector 111 and the other end connected to the inlet of the collector 111. Thus, a closed circuit in which the heat exchange medium circulates is formed.

그리고 열교환관(112)의 일측에는 열교환매체를 순환시키기 위한 순환펌프(113)가 마련되어 있다.One side of the heat exchange tube 112 is provided with a circulation pump 113 for circulating the heat exchange medium.

축열탱크(120)는 난방용수가 저수되어 있으며, 상기 열교환관(112)의 일부구간이 축열탱크(120)의 내부를 통과하도록 형성되어 있다.The heat storage tank 120 is stored with the heating water, and a portion of the heat exchange tube 112 is formed to pass through the inside of the heat storage tank 120.

열교환관(112)은 축열탱크(120) 내에서 난방용수와의 접촉면적을 최대화할 수 있도록 사행형상으로 연장되어 있으며, 태양열에 의해 가열된 열교환매체는 축열탱크(120)의 내부를 통과하는 동안 축열탱크(120)에 저수된 난방용수와 열교환되면서 난방용수를 가열하게 된다.The heat exchange tube 112 extends in a meandering shape to maximize the contact area with the heating water in the heat storage tank 120, and the heat exchange medium heated by solar heat passes through the heat storage tank 120. Heat-exchanging heat with the heating water stored in the heat storage tank 120 to heat the heating water.

그리고 축열탱크(120)에는 온수라인(125)도 내부를 관통하도록 설치되어 있어서 급탕공급을 위한 온수라인(125) 역시 축열탱크(120) 내에서 난방용수에 의해 가열될 수 있도록 형성되어 있다.And the heat storage tank 120 is also installed so that the hot water line 125 penetrates inside, so that the hot water line 125 for hot water supply is also formed to be heated by the heating water in the heat storage tank 120.

축열탱크(120)의 상측에는 난방용수가 출수되는 출수구(121)가 형성되어 있고, 하측에는 난방용수가 입수되는 입수구(122)가 마련되어 있다. 출수구(121)는 제1 연결관(131)에 연결되어 있으며, 제1 연결관(131)에는 난방대상지역에 설치되는 난방배관이 연결되어 있고, 난방배관은 제2 연결관(132)을 통해 상기 입수구(122)와 연결된다.On the upper side of the heat storage tank 120, a water outlet 121 through which heating water is discharged is formed, and on the lower side, an inlet 122 through which heating water is obtained. The outlet 121 is connected to the first connector 131, the heating pipe is installed in the heating target region is connected to the first connector 131, the heating pipe is connected through the second connector (132) It is connected to the inlet 122.

난방용수는 제1 연결관(131)에 설치된 난방용펌프(134)에 의해 제1 연결관(131), 난방용배관(133), 제2 연결관(132)을 통과하면서 축열탱크(120)로부터 배출된 후 다시 축열탱크(120)로 회수되는 폐회로를 순환하게 된다.The heating water is discharged from the heat storage tank 120 while passing through the first connecting pipe 131, the heating pipe 133, and the second connecting pipe 132 by the heating pump 134 installed in the first connecting pipe 131. After the cycle is circulated in the closed circuit recovered to the heat storage tank 120 again.

그리고 상기 제2 연결관(132)에는 제1 삼방밸브(135)가 마련되어 있으며, 축열탱크(120) 내에서 난방용수가 충분히 가열되지 못하여 설정된 온도로 난방이 이루어지기 어려운 경우에는 보조보일러(136)를 통해 난방용수가 가열된 후 난방용배관(133)을 재통과하도록 제1 삼방밸브(135)가 난방용수의 이동유로를 조절하게 된다.In addition, the second connecting pipe 132 is provided with a first three-way valve 135, the auxiliary boiler 136 when the heating water in the heat storage tank 120 is not sufficiently heated to the set temperature is difficult to achieve. After the heating water is heated through the first three-way valve 135 to control the flow passage of the heating water to pass through the heating pipe 133 again.

온도편차 제거수단(150)은 축열탱크(120) 내에서의 난방용수의 온도편차를 제거하기위한 것이다.The temperature deviation removing means 150 is for removing the temperature deviation of the heating water in the heat storage tank 120.

난방용수가 제1, 제2 연결관(131,132)과 난방용배관(133)을 따라 이동하면서 순환할 때에는 난방용수가 축열탱크(120)로부터 배출되거나 유입되는 과정에서 난 방용수 상호간에 열교환이 이루어지고 축열탱크(120) 내에서도 유동하기 때문에 축열탱크(120) 내의 전 영역에서 온도가 균일하다.When the heating water circulates while moving along the first and second connecting pipes 131 and 132 and the heating pipe 133, the heating water is exchanged with each other in the process of discharging or introducing the heating water from the heat storage tank 120, and the heat storage tank The temperature is uniform in all regions in the heat storage tank 120 because it also flows in the 120.

하지만 난방이 필요치 않은 시간대에 축열탱크(120) 내에서 난방용수가 장시간 정체되어 있는 경우에는 축열탱크(120) 내에서 온도가 높은 난방용수는 상측으로 이동하고 상대적으로 온도가 낮은 난방용수는 하방으로 이동함으로써 축열탱크(120) 내에서 난방용수의 높이에 따른 온도편차가 발생하게 된다.However, when the heating water is stagnant for a long time in the heat storage tank 120 during the time when no heating is required, the heating water having a high temperature in the heat storage tank 120 moves upward, and the heating water having a relatively low temperature moves downward. As a result, a temperature deviation occurs in accordance with the height of the heating water in the heat storage tank 120.

이렇게 축열탱크(120) 내에서 난방용수들이 온도편차가 발생하게 되면 축열탱크(120) 하부의 난방용수는 온도가 낮은 상태임에도 불구하고 축열탱크(120) 상측의 난방용수의 온도가 설정온도에 도달하여 제어기(153)에서 열교환매체를 순환시키지 않음으로써 축열탱크(120)에서의 축열을 정지시켜 축열탱크(120)의 축열효율이 저하되는 문제가 발생하기도 하고, 난방을 위해 난방용펌프(134)를 구동하여 난방용수를 순환시킬 때에는 초기에 충분히 가열되지 않은 난방용수가 난방용배관(133)을 따라 이동하게 되므로 난방효율이 낮아지게 되는 문제가 발생한다.When the temperature difference of the heating water in the heat storage tank 120 occurs in this way, the temperature of the heating water above the heat storage tank 120 reaches the set temperature despite the low temperature of the heating water in the heat storage tank 120. By not circulating the heat exchange medium in the controller 153 to stop the heat storage in the heat storage tank 120 may cause a problem that the heat storage efficiency of the heat storage tank 120 is lowered, and the heating pump 134 for heating When circulating the heating water by driving the heating water that is not sufficiently heated initially moves along the heating pipe 133 causes a problem that the heating efficiency is lowered.

따라서 온도편차 제거수단(150)을 축열탱크(120) 내부의 난방용수를 혼합하여 저수된 높이에 상관없이 온도가 균일하도록 하는 것이 바람직하다.Therefore, it is preferable that the temperature deviation removing means 150 mixes the heating water in the heat storage tank 120 so that the temperature is uniform regardless of the stored height.

본 실시예의 온도편차 제거수단(150)은 축열탱크(120)의 상측과 하측에 각각 마련되어 있는 혼합용출수구(123)와 혼합용입수구(124)를 상호 연결하는 혼합관(151)과, 혼합관(151)에 설치되는 혼합용펌프(152)와, 혼합용펌프(152)를 구동시키기 위한 제어기(153)를 포함한다.The temperature deviation removing means 150 of the present embodiment includes a mixing pipe 151 and a mixing pipe interconnecting the mixing outlet 123 and the mixing inlet 124 provided at the upper side and the lower side of the heat storage tank 120, respectively. A mixing pump 152 installed at 151 and a controller 153 for driving the mixing pump 152 are included.

제어기(153)는 난방용펌프(134)의 구동이 정지된 후 소정의 시간이 지나면 축열탱크(120) 내부에서의 난방용수의 혼합을 위해 혼합용펌프(152)를 구동시키며 혼합용펌프(152)의 구동에 의해 난방용수는 혼합용출수구(123)를 통해 출수되어 혼합관(151)을 따라 이동한 뒤 혼합용입수구(124)를 통해 축열탱크(120)로 재 유입된다.The controller 153 drives the mixing pump 152 to mix the heating water in the heat storage tank 120 after a predetermined time after the driving of the heating pump 134 is stopped and the mixing pump 152. By the operation of the heating water is discharged through the mixing spout 123 is moved along the mixing pipe 151 and then flows back into the heat storage tank 120 through the mixing inlet 124.

이렇게 온도편차 제거수단(150)에 의해 축열탱크(120) 내부에서 상측과 하측의 난방용수가 상호 혼합됨으로써 축열탱크(120) 내부 전 영역에서의 난방용수간 온도편차를 최소화하게 된다.Thus, by heating the temperature difference of the upper and lower side in the heat storage tank 120 by the temperature deviation removing means 150 to minimize the temperature difference between the heating water in the entire area of the heat storage tank 120.

상기 온도편차 제거수단(150)은 도 2에 도시된 것처럼 축열탱크(120)의 상부와 하부에 각각 설치되는 제1, 제2 온도센서(154,155)를 더 구비할 수도 있다.The temperature deviation removing means 150 may further include first and second temperature sensors 154 and 155 respectively installed at upper and lower portions of the heat storage tank 120 as shown in FIG. 2.

제어기(153)는 상기 제1, 제2 온도센서(154,155)에서 측정된 온도정보를 소정의 시간주기별로 취합하고, 제1, 제2 온도센서(154,155)에서 측정된 온도간의 편차가 설정된 일정수준 이상이 되면 혼합용펌프(152)를 구동시켜 난방용수를 혼합관(151)을 통해 순환시킴으로써 온도편차를 제거하도록 할 수 있다.The controller 153 collects the temperature information measured by the first and second temperature sensors 154 and 155 at predetermined time periods, and the predetermined level at which the deviation between the temperatures measured by the first and second temperature sensors 154 and 155 is set. When abnormal, the mixing pump 152 may be driven to circulate the heating water through the mixing pipe 151 to remove the temperature deviation.

도 3 및 도 4에는 본 발명에 따른 태양열을 이용한 난방 및 온수장치(200)의 제2 실시예가 도시되어 있다.3 and 4 illustrate a second embodiment of the heating and hot water device 200 using solar heat according to the present invention.

도면을 참조하면, 본 실시예의 태양열을 이용한 난방 및 온수장치(200)는 온도편차 제거수단(210)이 난방용펌프(134)와 난방용배관(133) 사이의 제1 연결관(131)의 관로 상에 설치되는 제2 삼방밸브(211)와, 제2 삼방밸브(211)와 축열탱크(120)를 연결하는 리턴관(212)과, 제2 삼방밸브(211)를 구동하는 컨트롤유닛(213)을 포함한다.Referring to the drawings, the heating and hot water device 200 using the solar heat of the present embodiment is the temperature deviation removing means 210 on the pipe line of the first connection pipe 131 between the heating pump 134 and the heating pipe 133. The second three-way valve 211 is installed in the, the return pipe 212 connecting the second three-way valve 211 and the heat storage tank 120, and the control unit 213 for driving the second three-way valve 211. It includes.

상기 컨트롤유닛(213)은 축열탱크(120)의 상부와 하부에 각각 설치되어 있는 제1, 제2 온도센서(154,155)와, 난방용배관(133)의 일측에 설치된 제3 온도센서(215), 난방용펌프(134)와 제1, 제2 삼방밸브(135,211), 순환펌프(113) 및 보조보일러(136)를 구동시키기 위한 제어기(214)를 포함한다.The control unit 213 may include first and second temperature sensors 154 and 155 installed at upper and lower portions of the heat storage tank 120, and a third temperature sensor 215 installed at one side of the heating pipe 133. And a controller 214 for driving the heating pump 134 and the first and second three-way valves 135 and 211, the circulation pump 113, and the auxiliary boiler 136.

본 실시예의 온도편차 제거수단(210)은 상기 제어기(214)에서 제1, 제2 온도센서(154,155)의 감지정보를 취합하여 제1, 제2 온도센서(154,155)에서 각각 측정된 난방용수의 온도차가 설정된 온도차 이상으로 벌어지면 상기 난방용펌프(134)를 구동시키고 제2 삼방밸브(211)를 통해 난방용수가 난방용배관(133)을 거치지 않고 리턴관(212)을 통해 축열탱크(120)로 바로 유입되도록 회수하게 된다.The temperature deviation removing unit 210 of the present exemplary embodiment collects the sensing information of the first and second temperature sensors 154 and 155 in the controller 214 to determine the heating water measured by the first and second temperature sensors 154 and 155, respectively. When the temperature difference is wider than the set temperature difference, the heating pump 134 is driven and the heating water directly through the second three-way valve 211 to the heat storage tank 120 through the return pipe 212 without passing through the heating pipe 133. It is recovered to be introduced.

따라서 축열탱크(120)에서 출수된 난방용수는 리턴관(212)을 통해 축열탱크(120)로 재유입되는 과정을 통해 난방용수들이 상호 혼합되어 온도편차가 없어지게 된다.Therefore, the heating water discharged from the heat storage tank 120 is mixed with each other through the process of being re-introduced into the heat storage tank 120 through the return pipe 212 so that the temperature deviation is eliminated.

본 실시예의 온도편차 제거수단(210)은 별도의 펌프를 설치하지 않고 기존의 난방용펌프(134)를 이용해 온도편차 제거를 위해 난방용수를 순환시키게 되므로 별도의 펌프를 설치하는데 따른 제작비용의 증가가 없어 제작비를 최소화할 수 있는 이점이 있다.Temperature deviation removing means 210 of the present embodiment circulates the heating water to remove the temperature deviation by using the existing heating pump 134 without installing a separate pump, so the increase in manufacturing cost due to installing a separate pump There is no advantage to minimize the production cost.

상기 제어부에서는 난방이 이루어질 때에는 제2 삼방밸브(211)를 조절하여 난방용수가 난방용배관(133)을 통해 이동하도록 경로를 조절하며, 제3 온도센서(215)에서 주기적으로 난방용수의 온도를 측정하고 난방용수의 온도가 낮고 집열유닛(110)에서 집열이 이루어지지 못하는 상황에서는 제1 삼방밸브(135)를 통해 난 방용수가 보조보일러(136)를 통과하도록 함으로써 난방용수를 설정된 온도로 가열한다.The control unit adjusts a path for heating water to move through the heating pipe 133 by adjusting the second three-way valve 211 when heating is performed, and periodically measures the temperature of the heating water by the third temperature sensor 215. In a situation where the temperature of the heating water is low and the heat is not collected in the heat collecting unit 110, the heating water is allowed to pass through the auxiliary boiler 136 through the first three-way valve 135 to heat the heating water to the set temperature.

본 실시예의 나머지 구성요소는 제1 실시예와 동일하므로 동일번호를 부여하고 상세한 설명은 생략한다.Since the remaining components of the present embodiment are the same as the first embodiment, the same reference numerals are used and detailed description thereof will be omitted.

이렇게 본 발명에 따른 태양열을 이용한 난방 및 온수장치(100,200)는 축열탱크(120) 내에서 난방용수간의 온도편차를 없앰으로써 축열 및 난방효율을 높이게 되며, 특히 제2 실시예의 온도편차 제거수단(210)은 종래의 난방용펌프(134)를 이용해 난방용수를 자체 순환시키도록 함으로써 온도편차 제거수단(210)의 설치에 따른 비용증가를 최소화하게 된다.Thus, the heating and hot water devices 100 and 200 using solar heat according to the present invention increase the heat storage and heating efficiency by eliminating the temperature deviation between the heating water in the heat storage tank 120, in particular, the temperature deviation removing means 210 of the second embodiment. By using the conventional heating pump 134 to circulate the heating water by itself to minimize the increase in cost due to the installation of the temperature deviation removing means 210.
