본 발명은 태양열 집열 및 축열시스템을 가스보일러와 연계시켜 보조열원으로 사용할 수 있는 태양열보일러시스템에 관한 것으로, 더욱 상세하게는 센서에 의해 태양열 축열조 각 부의 온도, 태양열 집열기 온도, 난방수 온도 등을 감지하여 최적의 상태로 태양열집열 및 축열시스템과 가스보일러를 가동시켜 에너지효율을 증대시킨 가정용보일러와 연계한 태양열 급탕, 난방 시스템에 관한 것이다.The present invention relates to a solar boiler system that can be used as an auxiliary heat source by linking a solar collector and a heat storage system with a gas boiler. The present invention relates to a solar hot water supply and heating system in connection with a home boiler which increases energy efficiency by operating a solar heat collection and heat storage system and a gas boiler in an optimal state.
통상의 보일러는 기름 또는 가스를 연료로 이용하여 난방용 및 생활용 온수를 공급하였으나, 화석화 연료의 가격이 상승하고 사용에 따른 공해문제가 커지면서 점차 대체에너지 사용이 확대되어 가고 있는 실정이다.Conventional boilers supply hot water for heating and living using oil or gas as fuel, but the use of alternative energy is gradually increasing as the price of fossil fuel increases and the pollution problem caused by use increases.
근래에는 초기 설치비용이 많이 소요되나 별도의 유지비가 소요되지 않으면서 공해문제도 야기 시키지 않는 태양열을 이용한 태양열보일러가 많이 보급되었으나, 우리나라와 같이 4계절이 뚜렷하면서 태양의 연중고도가 바뀌고 날씨변화가 잦은 곳에서는 단순히 태양열에만 의존하는 보일러시스템으로는 난방과 생활용 온수를 공급하는 열원의 공급이 충분하지 못하였다.In recent years, many solar boilers using solar heat, which require a lot of initial installation costs but do not require additional maintenance costs, do not cause pollution problems.However, as in Korea, the four seasons are distinct and the year-round altitude of the sun changes and the weather changes. In many cases, boiler systems that rely solely on solar heat did not have enough heat to provide heating and hot water for living.
즉, 태양열만을 열원으로 하는 보일러시스템을 위해서는 태양열집열기의 크기가 커져야 하는데 이와 같은 시스템을 갖추기 위해서는 많은 비용과 넓은 설치공간이 필요하기 때문에 일반 가정집에서는 사용하기 어려운 문제점이 있었다.That is, the size of the solar collector should be increased for the boiler system using only solar heat as a heat source, but it is difficult to use in a general home because it requires a large cost and a large installation space.
이에 따라, 태양열이 집중되는 낮시간에 태양열을 축적하고, 태양열이 없는 흐린날 또는 밤시간에 전기를 보조열원으로 이용하여 축열조에 온수를 채우는 구조의 개량된 태양열보일러시스템이 개발되게 되었으나, 태양열만으로는 온수와 난방을 사용하는데 충분한 온수를 가열시킬 수 없으므로 축열조의 열충전이 태양열이 집중되는 낮시간보다는 태양열집열기가 작동되지 않는 밤시간에 심야전기에 의해 대부분 이루어져 태양열집열기를 효율적으로 이용하지 못하는 문제점이 있었다.As a result, an improved solar boiler system has been developed in which solar heat is accumulated during daytime when solar heat is concentrated and hot water is charged to the heat storage tank by using electricity as an auxiliary heat source on a cloudy day or at night when there is no solar heat. Since the hot water cannot be heated enough to use the hot water and heating, the heat charging of the heat storage tank is mostly made by the late-night electricity at night when the solar collector is not operated, rather than the daytime when the solar heat is concentrated, so that the solar collector cannot be efficiently used. there was.
또한 종래 대부분의 태양열 집열기와 축열조 사이의 배관이 열매체를 물을 사용하는 단일배관으로 형성되어, 겨울철등에는 외부에 설치된 집열기 배관쪽의 배관이 동파되는 등의 문제점이 있다.In addition, since most of the conventional pipes between the solar collector and the heat storage tank are formed of a single pipe using heat medium for water, there is a problem in that the pipes of the collector pipe side installed outside are freeze in winter.
상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 센서에 의해 태양열 축열조 각 부의 온도, 태양열집열기 온도, 난방수 온도 등을 감지하고 태양열집열기 및 가스보일러와 연결된 열교환코일을 축열조 내부에 각각 설치하여, 난방열원으로 태양열과 가스보일러를 사용함과 아울러 온수가열 열원으로 태양열을 사용하되 센서에 감지된 각 부분의 온도에 따라 필요시 온수가열 및 난방가열의 보조열원으로 가스보일러를 이용하도록 된 태양열보일러시스템을 제공하는데 있다.An object of the present invention for solving the above problems is to detect the temperature, solar collector temperature, heating water temperature, etc. of each part of the solar heat storage tank by the sensor and to install a heat exchange coil connected to the solar heat collector and the gas boiler inside the heat storage tank, respectively, In addition to using solar heat and gas boilers as heating heat sources, it uses solar heat as hot water heating sources, and uses a gas boiler as an auxiliary heat source for hot water heating and heating heating, depending on the temperature of each part detected by the sensor. To provide.

또한, 본 발명 시스템의 초기 설치시 집열배관(220) 내에 부동액 충전시, 배관내의 공기를 빼면서 부동액만을 배관내에 충전할 수 있도록 충전배관(463) 및 밸브(460, 461, 462)를 구성하였으며, 부동액의 증발이나 과압에 의해 집열배관(220)내의 부동액이 소진될 경우에는 열매체 충전탱크(470)와 연결된 차압펌프(411)가 작동하여 부동액을 집열배관에 충전할 수 있도록 구성하였다.In addition, the filling pipe 463 and the valves (460, 461, 462) was configured to fill only the antifreeze in the pipe while removing the air in the pipe during the initial installation of the system of the present invention, filling the antifreeze in the heat collecting pipe (220), When the antifreeze in the heat collecting pipe 220 is exhausted by the evaporation or overpressure of the antifreeze, the differential pressure pump 411 connected to the heat medium filling tank 470 operates to fill the antifreeze in the heat collecting pipe.
특히 상기 충전배관(463)은 집열배관에 연결되어 열매체충전탱크(470) 상부 공간에 설치되고, 밸브(460, 461, 462)는 충전배관에 설치된 밸브(462)와 충전배관(463)을 중심으로 양측 집열배관(220)에 설치된다.In particular, the filling pipe 463 is connected to the heat collecting pipe is installed in the upper space of the heat medium filling tank 470, the valve 460, 461, 462 is centered on the valve 462 and the filling pipe 463 installed in the filling pipe It is installed on both side heat collecting pipe 220.

The heat medium circulating inside the heat collecting pipe 220 uses an antifreeze (preferably water 50vol% + ethylene glycol 50vol%) having a large heat capacity and a low freezing temperature and installs a circulation pump 410 for circulation. do.
상기 온도센서(650)는 상기 태양열집열기(200)에서 가열된 온수가 배출되는 배출구측에 설치되는 것이 바람직하다.The temperature sensor 650 is preferably installed on the outlet side for discharging the hot water heated in the solar collector 200.
아울러, 상기 안전밸브(450)는 상기 집열배관(220)을 흐르는 온수에 포함된 이물질과 상기 태양열집열기(200)에서 가열되면서 발생되는 관석(罐石) 등의 이물 질을 밖으로 배출시키는 역할도 병행할 수 있다.In addition, the safety valve 450 also discharges the foreign matter such as capstone (관 石) generated while being heated in the solar collector 200 and the foreign matter contained in the hot water flowing through the collecting pipe 220 in parallel. can do.
한편, 상기 축열조(100) 내부에 설치된 제1열교환코일(110)에서 태양열집열기(200)에서 가열된 부동액이 집열배관(220)을 순환하여 제1열교환코일(110)을 통해 상기 축열조(100)내로 순환하여 축열하게 된다.Meanwhile, the antifreeze heated in the solar heat collector 200 in the first heat exchange coil 110 installed in the heat storage tank 100 circulates through the heat collecting pipe 220 and the heat storage tank 100 through the first heat exchange coil 110. Circulate inside and regenerate.
상기와 같이 직접 태양열집열기(200)와 축열조(100)가 직접 열교환되도록 한 이유는, 축열조 하부에 설치된 제 1열교환코일(110) 부분에서 부동액과 축열조의 축열매체가 열교환이 되어 축열조 하부의 온도가 상승하게 되면, 이 축열매체는 밀도차에 의해 축열조의 상부로 올라가서 저장되는데, 이 저장된 온수를 급탕 및 난방에 효과적으로 이용하기 위함이다.The reason for the direct heat exchange between the solar collector 200 and the heat storage tank 100 as described above is that the antifreeze and the heat storage medium of the heat storage tank are heat-exchanged at the portion of the first heat exchange coil 110 installed under the heat storage tank so that the temperature of the bottom of the heat storage tank is increased. When raised, the heat storage medium rises to the top of the heat storage tank due to the density difference, and is used to effectively use the stored hot water for hot water supply and heating.
상기 집열배관(220)에는 가열된 부동액을 순환시킬 수 있는 펌프(410), 일정방향으로 온수가 순환되도록 하는 체크밸브(440)와 함께 고온의 온수에 의해 발생된 압력을 측정하는 압력계(430)와 압력을 감압시키는 팽창탱크(420), 그리고 과압안전밸브(450)가 설치되어 있다.The collecting pipe 220 includes a pump 410 capable of circulating the heated antifreeze, and a pressure gauge 430 for measuring pressure generated by hot water of high temperature together with a check valve 440 for circulating hot water in a predetermined direction.

Thus, the antifreeze in the heat collecting pipe 220 was prevented from entering the heat medium filling tank 470.
집열배관(220), 제 1열교환코일(230)에 의해 상기 태양열집열기(200)와 열교환되는 축열조(100)는 하부에 직수가 공급되는 직수유입관(140)이 연결되어 있으며 상부에는 온수배출관(150)이 연결되어 있다. 상기 직수유입관(140)에는 이물질을 배출시킬 수 있는 드레인밸브(141)가 설치되어 있으며, 상기 온수배출관(150)에는 상기 축열조(100)의 과열과 과압을 방지하기 위해 축열조의 온도가 설정온도 이상이 되면 작동하여 축열조의 물을 일부 배출하도록 하는 자동밸브(151)와 드레인배관(160)을 구성하였으며, 축열조의 물이 과열될 경우, 사용자의 안전을 위하여 일정온도로 출탕이 되도록 믹싱밸브(153)를 설치하였다. 이 외에도 축열조의 압력을 항상 나타내어 보여주는 압력계(431), 축열조의 과압을 방지하기 위한 과압안전밸브(451)가 축열조에 설치되어 있으며, 이 안전밸브(451)가 작동하였을 때, 축열조의 물을 외부로 배출하기 위한 드레인배관(160)이 구성되어 있다.The heat storage tank 100 which is heat-exchanged with the solar heat collector 200 by the heat collecting pipe 220 and the first heat exchange coil 230 is connected to a direct inflow pipe 140 through which direct water is supplied, and a hot water discharge pipe at the top thereof. 150 is connected. The direct water inlet pipe 140 is provided with a drain valve 141 for discharging the foreign matter, the hot water discharge pipe 150 is the temperature of the heat storage tank to prevent overheating and overpressure of the heat storage tank 100 is set temperature. When the operation is over, the automatic valve 151 and the drain pipe 160 are configured to discharge part of the heat storage tank. When the water in the heat storage tank is overheated, the mixing valve is heated to a certain temperature for the user's safety. 153). In addition, a pressure gauge 431 which always shows the pressure of the heat storage tank, and an overpressure safety valve 451 for preventing overpressure of the heat storage tank are installed in the heat storage tank. When the safety valve 451 is operated, the water of the heat storage tank is externally supplied. The drain pipe 160 for discharging the furnace is configured.
또한 축열조(100) 외부의 온수배출관(150) 일지점에는 삼방밸브(154)가 설치되어 있어 온도센서(610)에서 측정한 축열조 내부온도가 온수로 사용가능한 45℃이상일 경우 태양열 콘트롤러(510)가 급탕열교환기(370) 쪽으로의 유로를 차단하여 온수가 삼방밸브연결관(155)을 통해 급탕열교환기(370)를 지난 온수배출관(150)에 연결되도록 구성된다.In addition, a three-way valve 154 is installed at one point of the hot water discharge pipe 150 outside the heat storage tank 100, and when the internal temperature of the heat storage tank measured by the temperature sensor 610 is 45 ° C. or more available as hot water, the solar controller 510 is By blocking the flow path toward the hot water heat exchanger 370, the hot water is configured to be connected to the hot water discharge pipe 150 passing the hot water heat exchanger 370 through the three-way valve connecting pipe 155.
또한 상기 온수배출관 시작지점과 삼방밸브(154) 사이의 축열조(100) 외부의 온수배출관(150) 일지점에는 믹싱밸브(153)를 구비한 직수우회관(130) 일측이 연결되어 이 직수우회관(130)의 타측과 연결된 직수유입관(140)을 통해 믹싱밸브(153)의 개방에 따라 직수가 유입되도록 구성되어 온도센서(610)에서 측정한 축열조 내부온도가 사용자가 직접 사용하기 곤란할 정도로 과열(60℃ 이상)되는 경우에는 믹싱밸브(153)가 개방되어 축열조(100)에서 토출되는 온수배출관(150)을 지나는 온수와 직수유입관(140)으로부터 공급되는 냉수가 혼합되도록 하여 온수의 온도를 낮추 어 적정온도로 공급하게 된다. 이 경우에도 삼방밸브(154)가 급탕열교환기(370) 쪽으로의 유로를 차단하고 삼방밸브연결관(155)쪽으로 절환되어 급탕열교환기(370)를 지난 온수배출관(150)에 연결하게 된다. In addition, the hot water discharge pipe 150 outside of the heat storage tank 100 between the start point of the hot water discharge pipe and the three-way valve 154 is connected to one side of the direct water draining chamber 130 having a mixing valve 153 and is directly connected to the direct water discharge pipe. Direct water flows in accordance with the opening of the mixing valve 153 through the direct water inlet pipe 140 connected to the other side of the 130, so that the internal temperature of the heat storage tank measured by the temperature sensor 610 is hard to be directly used by the user. (60 ° C. or more), the mixing valve 153 is opened so that the hot water passing through the hot water discharge pipe 150 discharged from the heat storage tank 100 and the cold water supplied from the direct water inlet pipe 140 are mixed to adjust the temperature of the hot water. It is lowered and supplied at the proper temperature. In this case, the three-way valve 154 blocks the flow path toward the hot water heat exchanger 370 and is switched to the three-way valve connection pipe 155 to connect the hot water heat exchanger 370 to the hot water discharge pipe 150.
한편, 상기 축열조(100)의 내부에는 상기 태양열집열기(200)와 집열배관(220) 을 매개로 연결된 제1열교환코일(110) 및, 입구관(170)과 배출관(180)을 매개로 연결된 제2열교환코일(120)이 설치되어 있어, 상기 축열조(100)에 저장된 온수와 열교환이 이루어지며, 외부에는 상기 제1열교환코일(110)과 제2열교환코일(120)이 설치된 부분의 온수온도를 측정할 수 있는 온도센서(640, 620)가 각각 설치되어 있어 측정된 온도정보를 전기적 신호로 태양열콘트롤러(510)에 송출한다.On the other hand, inside the heat storage tank 100, the first heat exchange coil 110 and the inlet pipe 170 and the discharge pipe 180 connected through the solar collector 200 and the heat collecting pipe 220 as a medium. Since the two heat exchange coils 120 are installed, heat exchange is performed with the hot water stored in the heat storage tank 100, and the hot water temperature of the portion where the first heat exchange coils 110 and the second heat exchange coils 120 are installed is externally provided. Temperature sensors 640 and 620 that can measure are installed, respectively, and transmit the measured temperature information to the solar controller 510 as an electrical signal.
또한, 상기 온도센서(620) 위로 별도의 온도센서(610)가 설치되어 상기 축열조(100)의 최상부분의 온도를 측정하여 상기 태양열콘트롤러(510)에 전기적 신호로 송출한다.In addition, a separate temperature sensor 610 is installed above the temperature sensor 620 to measure the temperature of the uppermost portion of the heat storage tank 100 and sends it to the solar controller 510 as an electrical signal.
입구관(170)과 배출관(180)을 매개로 상기 축열조(100)와 연결된 가스보일러(300)는 버너(310)에 의해 가열되는 열교환기(320) 및 펌프(330)가 설치되어 있으며, 난방배관(340)에 의해 외부 난방부하(500)와 연결된다.The gas boiler 300 connected to the heat storage tank 100 through the inlet pipe 170 and the discharge pipe 180 is provided with a heat exchanger 320 and a pump 330 heated by the burner 310, and is heated. It is connected to the external heating load 500 by the pipe 340.
한편, 상기 난방배관(340)에는 삼방밸브(350, 360)가 설치되어 있어, 제2열교환코일(120)과 연결된 입구관(170) 및 온수가열배관(380)이 각각 연결되며, 상기 제2열교환코일(120)의 타측과 연결된 배출관(180)은 보일러(300) 외부에서 삼방 밸브(371)을 통해 난방배관(340)의 난방수출구측 배관에 연결된다. On the other hand, the heating pipe 340 is provided with a three-way valve (350, 360), the inlet pipe 170 and the hot water heating pipe 380 connected to the second heat exchange coil 120 are connected, respectively, the second The discharge pipe 180 connected to the other side of the heat exchange coil 120 is connected to the heating outlet port of the heating pipe 340 through the three-way valve 371 outside the boiler 300.
또한 필요시 삼방밸브(371)의 절환에 따라 우회배관(372)을 따라 우회하여 난방배관(340)의 난방수입구측 배관에 연결된다. In addition, according to the switching of the three-way valve (371) if necessary bypasses along the bypass pipe 372 is connected to the heating inlet side pipe of the heating pipe (340).
또한 상기 삼방밸브 중 입구관(170)에 연결된 삼방밸브(350)는 배관이 용이하게 연결되도록 보일러 외부에 설치구성된다.In addition, the three-way valve 350 connected to the inlet pipe 170 of the three-way valve is installed outside the boiler so that the pipe is easily connected.
아울러, 상기 온수가열배관(380)은 가스보일러(300)의 일측에 설치된 급탕열교환기(370)를 순환한 후 난방부하(500)에서 가스보일러(300)의 열교환기(320)로 향하는 난방수 입구쪽에 연결된다. 이때, 상기 연결위치는 상기 삼방밸브(350)보다 윗쪽, 즉 열교환기(320)에 가까운 곳에 연결되는 것이 바람직하다.In addition, the hot water heating pipe 380 circulates the hot water supply heat exchanger 370 installed on one side of the gas boiler 300, the heating water from the heating load 500 to the heat exchanger 320 of the gas boiler 300. It is connected to the entrance. At this time, the connection position is preferably connected to the upper side than the three-way valve 350, that is close to the heat exchanger (320).
만약, 상기 온수가열배관(380)이 위에서 설명한 위치 이외의 곳에 연결되면 제 2열교환코일(120)을 순환하는 온수가 가스보일러(300)의 열교환기(320)을 거치지 않게 되므로 발명의 목적을 이룰 수 없게 된다.If the hot water heating pipe 380 is connected to a place other than the position described above, the hot water circulating in the second heat exchange coil 120 does not pass through the heat exchanger 320 of the gas boiler 300, thereby achieving the object of the present invention. It becomes impossible.
한편, 상기 급탕열교환기(370)에는 상기 온수가열배관(380)외에 축열조(100)와 연결된 온수배출관(150)이 통과하므로, 상기 온수가열배관(380)과 온수배출관(150) 상호간에 열교환이 이루어진다.On the other hand, since the hot water heat exchanger 370 passes through the hot water discharge pipe 150 connected to the heat storage tank 100 in addition to the hot water heating pipe 380, heat exchange between the hot water heating pipe 380 and the hot water discharge pipe 150 is mutually performed. Is done.
상기 난방배관(340)의 일측에는 온도센서(630)가 설치되어 있어 가스보일러(300)를 순환하는 온수의 온도를 측정하여 태양열콘트롤러(510)로 송출한다. 상기 태양열콘트롤러(510)는 상기 온도센서(610, 620, 630, 640, 650)에서 측정된 온도를 사용자가 설정한 온도와 비교하여 삼방밸브(350, 360, 154) 및 밸브(460, 461, 462)의 작동을 제어하며, 메인콘트롤러(520)와도 전기적 신호장치로 연결되어 있어 가스보일러(300)의 동작도 제어한다.One side of the heating pipe 340 is provided with a temperature sensor 630 to measure the temperature of the hot water circulating the gas boiler 300 is sent to the solar controller 510. The solar controller 510 compares the temperature measured by the temperature sensors 610, 620, 630, 640, and 650 with the temperature set by the user, and the three-way valves 350, 360, 154, and valves 460, 461, It controls the operation of the 462, and is also connected to the main controller 520 as an electrical signal device to control the operation of the gas boiler (300).
보다 구체적으로 펌프의 작동과 관련하여 설명하자면, 축열조 중부에 위치한 온도센서(620)에서 측정된 온도가 난방배관(340)의 환수배관 온도보다 높을 때에는 삼방밸브(350)가 태양열 축열조 입구방향(170)으로 전환되어 태양열 축열조 입구로 흐르게 되며, 태양열 축열조 배출관(180)을 나오는 온수의 흐름은 두 가지로 나누어진다. 즉, 태양열 축열조에서 열을 받아 배출관(180)에서 나온 온수는 삼방밸브(154)에 의 전환방향에 따라 곧바로 난방부하(500)로 흘러 들어가든지, 혹은 가스보일러(300)를 통과하여 난방부하(500)로 흘러 들어가든지 한다. 만약, 온도센서(620)에서 측정된 온도가 난방배관(340)의 환수배관 온도보다 낮을 때에는 삼방밸브(350)이 가스보일러 방향으로 전환됨에 따라 보일러로 흘러 들어가게 되며, 이때 보일러가 가동되어 보일러에서 열은 얻은 온수는 난방부하(500)로 흘러들어가 순환하게 된다.More specifically, in relation to the operation of the pump, when the temperature measured by the temperature sensor 620 located in the middle of the heat storage tank is higher than the return pipe temperature of the heating pipe 340, the three-way valve 350 is the solar heat storage tank inlet direction 170 Is converted to) and flows to the inlet of the solar heat storage tank, the flow of hot water exiting the solar heat storage tank discharge pipe 180 is divided into two. That is, the hot water from the solar heat storage tank receives the heat from the discharge pipe 180 flows directly into the heating load 500 according to the switching direction to the three-way valve 154, or passes through the gas boiler 300 heating load ( Or 500). If the temperature measured by the temperature sensor 620 is lower than the return pipe temperature of the heating pipe 340, the three-way valve 350 flows into the boiler as it is switched to the gas boiler direction. Heated hot water flows into the heating load 500 to circulate.
축열조 내 난방열교환코일(120)에서 열교환을 이룬 난방수는 배출관(180)을 통하여 삼방밸브(371)를 지나 외부 난방부하(500)의 난방배관(340)의 난방수출구측 배관에 연결되어 운전하게 되면 태양열 순환펌프(460) 한대의 동작만으로 운전이 가능하게 되고, 불가피하여 보일러(300)와 축열조(100) 설비가 상당 거리 떨어져 있을 때, 즉 순환양정이 부족할 때 순환펌프(330)을 활용할 수 있도록 하였다.The heating water that has undergone heat exchange in the heating heat exchange coil 120 in the heat storage tank is connected to the heating outlet side pipe of the heating pipe 340 of the external heating load 500 through the three-way valve 371 through the discharge pipe 180 and operated. When the solar circulation pump 460 can be operated only by one operation, and inevitably when the boiler 300 and the heat storage tank 100 are located at a considerable distance, that is, when the circulation head is insufficient, the circulation pump 330 is utilized. To make it possible.
즉, 순환펌프(330)을 활용할 필요가 있을 때는 난방부하(500)에 연결된 난방배관(340)의 난방수출구측 배관이 아닌 삼방밸브(371)의 절환에 따라 우회배관(372)을 따라 우회하여 난방배관(340)의 난방수입구측 배관에 연결하여야 한다.That is, when it is necessary to utilize the circulation pump 330, the bypass along the bypass pipe 372 in accordance with the switching of the three-way valve 371, not the heating export outlet side pipe of the heating pipe 340 connected to the heating load 500. Should be connected to the heating inlet side of the heating pipe (340).
우회배관(372)을 통해 난방수입구측 배관에 연결하는 방법은 축열조(100) 중부의 온도를 감지하여 난방으로 가능한 온도일 경우에는 메인콘트롤러(520)는 보일러의 기능 중 버너의 동작은 중지하고 순환펌프(330)만 동작할 수 있도록 제어장치를 구성하였다.The method of connecting to the heating inlet-side pipe through the bypass pipe 372 is to detect the temperature in the heat storage tank 100, the main controller 520 stops the operation of the burner during the boiler function if the temperature is possible by heating The control device was configured to operate only the circulation pump 330.
도 2는 본 발명의 일실시예에 따른 온수가열 및 난방가열 개별순환도를 도시한 것으로서, 태양열집열기(200)의 온도센서(650)에서 측정된 부동액의 온도가 축열조(100) 하부에 설치된 온도센서(640)에서 측정된 온수의 온도보다 7℃이상 높으면, 집열배관(220)에 설치된 펌프(461)가 작동하여 상기 온도센서(650, 640)에서 측정된 온도의 편차가 3℃이하가 될 때까지 온수의 순환이 이루어져, 축열조(100) 내부에 저장된 물과 상기 태양열집열기(200)에서 가열된 열매체(부동액)간에 축열조내부에 설치된 제 1열교환코일에서 열교환이 이루어진다. 이때, 상기 온도편차는 사용자의 설정에 따라 달라질 수 있다.Figure 2 shows the individual circulation diagram of the hot water heating and heating heating according to an embodiment of the present invention, the temperature of the antifreeze measured by the temperature sensor 650 of the solar collector 200 is the temperature installed under the heat storage tank (100) When the temperature of the hot water measured by the sensor 640 is 7 ° C. or more, the pump 461 installed in the heat collecting pipe 220 is operated so that the deviation of the temperature measured by the temperature sensors 650 and 640 becomes 3 ° C. or less. The hot water is circulated until heat exchange is performed in the first heat exchange coil installed in the heat storage tank between the water stored in the heat storage tank 100 and the heat medium (antifreeze) heated in the solar collector 200. In this case, the temperature deviation may vary according to the user's setting.
도 3은 본 발명의 일실시예에 따른 난방수가열 순환도를 도시한 것으로서, 태양열콘트롤러(510)에 수신된 축열조(100)의 온수온도(온도센서(620)에서 측정된 온도)가 난방부하(500)를 순환하고 배출되는 온수의 온도(온도센서(630)에서 측정된 온도) 보다 높은 경우의 온수흐름을 나타낸다.3 illustrates a heating water heating circulation diagram according to an embodiment of the present invention, wherein the hot water temperature (temperature measured by the temperature sensor 620) of the heat storage tank 100 received by the solar controller 510 is a heating load. The hot water flow in the case of higher than the temperature of the hot water (temperature measured by the temperature sensor 630) circulating 500 is discharged.
이 경우 태양열콘트롤러(510)는 전기적 신호를 통해 난방배관(340)에 설치결 합된 삼방밸브(350)를 상기 축열조(100)의 제 2열교환코일(120)과 연결된 입구관(170)으로 개방시킴과 아울러 펌프(460)을 가동시켜, 상기 난방부하(500)에서 열을 빼앗긴 온수가 상기 제2열교환코일(120)을 순환하면서 축열조(100)에 저장된 열을 흡수하여 다시 가스보일러(300)의 열교환기(320)로 순환되든지, 혹은 가스보일러(300)을 순환하지 않고 바로 난방부하(500)로 들어가 순환하도록 한다.In this case, the solar controller 510 opens the three-way valve 350 installed in the heating pipe 340 through the electrical signal to the inlet pipe 170 connected to the second heat exchange coil 120 of the heat storage tank 100. In addition, by operating the pump 460, the hot water deprived of the heat from the heating load 500 circulates the second heat exchange coil 120 while absorbing the heat stored in the heat storage tank (100) of the gas boiler (300) again It is circulated to the heat exchanger 320, or circulates directly into the heating load 500 without circulating the gas boiler 300.
상기 온수의 순환은 제2열교환코일(120)부근에 설치된 온도센서(620)에서 측정된 온도가 50℃이상에서 순환을 시작하여 온도센서(620)의 온도가 45℃이하가 될 때까지, 혹은 난방부하(500) 출구의 온도보다 5℃이하로 높을 까지, 순환을 하게 되며, 상기 입구관(170)에 설치된 펌프(460)에 의해 온수의 순환이 원활히 이루어진다.The circulation of the hot water is started until the temperature measured by the temperature sensor 620 installed near the second heat exchange coil 120 starts at 50 ° C. or higher until the temperature of the temperature sensor 620 is 45 ° C. or lower, or The circulation is up to 5 ° C. or less than the temperature of the outlet of the heating load 500, and the hot water is smoothly circulated by the pump 460 installed in the inlet pipe 170.
따라서, 본 난방수가열 순환에서는 난방부하(500)에서 열을 빼앗긴 난방수가 태양열집열기(200)에 의해 가열된 축열조(100)에서 예열된 후 가스보일러(300)의 열교환기(320)로 순환되어 재가열되므로 가스보일러(300)의 열효율을 높일 수 있으며 동시에 연료를 절약할 수 있는 장점이 있다.Therefore, in the heating water heating circulation, the heating water deprived of heat from the heating load 500 is preheated in the heat storage tank 100 heated by the solar collector 200 and then circulated to the heat exchanger 320 of the gas boiler 300. Reheating can increase the thermal efficiency of the gas boiler 300 and at the same time have the advantage of saving fuel.
도 4 내지 6은 본 발명의 일실시예에 따른 온도에 따른 급탕가열 순환도를 도시한 것으로서, 태양열콘트롤러(510)에 수신된 축열조(100)의 온수온도(온도센서(610)에서 측정된 온도)가 설정온도보다 낮아 목욕용 또는 취사용으로 사용하기에 부적합한 경우의 온수순환을 나타낸다.(도 4참조)4 to 6 illustrate the hot water heating circulation according to the temperature according to an embodiment of the present invention, the hot water temperature of the heat storage tank 100 received by the solar controller 510 (temperature measured by the temperature sensor 610). ) Is lower than the set temperature, it shows the circulation of hot water when it is not suitable for use in bathing or cooking (see Fig. 4).
이 경우 태양열콘트롤러(510)는 난방배관(340)에 설치된 가스보일러(300)를 작동시키고 삼방밸브(360)를 온수가열배관(380)쪽으로 개방시켜 열교환기(320)에서 가열된 온수가 온수가열배관(380)을 통해 급탕열교환기(370)로만 순환되도록 한다.In this case, the solar controller 510 operates the gas boiler 300 installed in the heating pipe 340 and opens the three-way valve 360 toward the hot water heating pipe 380 to heat the hot water heated by the heat exchanger 320.

아울러, 태양열집열기(200)에서 가열된 부동액과 제1열교환코일에서 열교환된 온수가 상기 축열조(100)의 온수를 가열한다.In addition, the antifreeze heated in the solar collector 200 and the hot water heat exchanged in the first heat exchange coil heat the hot water of the heat storage tank 100.
따라서, 상기 태양열집열기(200)에서 가열된 부동액과 열교환된 온수의 온도가 상승하여 밀도차에 의해 축열조(100)의 상층부에 저장됨에 따라, 사용자가 사용하는 만큼의 물만이 신속하게 급탕 가열되므로, 사용자에게 고온의 온수를 보다 빠르게 제공할 수 있는 장점이 있다. Therefore, as the temperature of the hot water heat-exchanged with the antifreeze heated in the solar collector 200 is stored in the upper layer of the heat storage tank 100 due to the difference in density, only water as much as the user uses is rapidly heated and heated. There is an advantage that can provide hot water to the user faster.
또한 상기 축열조(100) 외부의 온수배출관(150) 일지점에는 삼방밸브(154)가 설치되어 있어 온도센서(610)에서 측정한 축열조 내부온도가 온수로 사용가능한 45℃이상일 경우 태양열 콘트롤러(510)가 급탕열교환기(370) 쪽으로의 유로를 차단하여 온수가 삼방밸브연결관(155)을 통해 급탕열교환기(370)를 지난 온수배출관(150)에 연결되도록 구성된다.(도 5참조)In addition, a three-way valve 154 is installed at one point of the hot water discharge pipe 150 outside the heat storage tank 100, and when the internal temperature of the heat storage tank measured by the temperature sensor 610 is 45 ° C. or higher usable as hot water, the solar controller 510. Blocks the flow path toward the hot water supply heat exchanger 370 so that the hot water is connected to the hot water discharge pipe 150 passing the hot water heat exchanger 370 through the three-way valve connecting pipe 155 (see FIG. 5).
또한 상기 축열조(100) 외부의 온수배출관(150) 일지점에는 믹싱밸브(153)를 구비한 직수우회관(130) 일측이 연결되어 이 직수우회관(130)의 타측과 연결된 직수유입관(140)을 통해 믹싱밸브(153)의 개방에 따라 직수가 유입되도록 구성되어 온도센서(610)에서 측정한 축열조 내부온도가 사용자가 직접 사용하기 곤란할 정도로 과열(60℃ 이상)되는 경우에는 믹싱밸브(153)가 개방되어 축열조(100)에서 토출되는 온수배출관(150)을 지나는 온수와 직수유입관(140)으로부터 공급되는 냉수가 혼합되도록 하여 온수의 온도를 낮추어 적정온도로 공급하게 된다. 이 경우에도 삼방밸브(154)가 급탕열교환기(370) 쪽으로의 유로를 차단하고 삼방밸브연결관(155)쪽으로 절환되어 급탕열교환기(370)를 지난 온수배출관(150)에 연결하게 된다. (도 6참조)In addition, one side of the direct bypass pipe 130 having a mixing valve 153 is connected to one point of the hot water discharge pipe 150 outside the heat storage tank 100, and a direct inflow pipe 140 connected to the other side of the direct bypass pipe 130. Direct water flows in accordance with the opening of the mixing valve 153 through the) and when the internal temperature of the heat storage tank measured by the temperature sensor 610 is overheated so that it is difficult for a user to directly use the mixing valve 153. ) Is opened to allow the hot water passing through the hot water discharge pipe 150 discharged from the heat storage tank 100 and the cold water supplied from the direct water inflow pipe 140 to be lowered and supplied at an appropriate temperature. In this case, the three-way valve 154 blocks the flow path toward the hot water heat exchanger 370 and is switched to the three-way valve connection pipe 155 to connect the hot water heat exchanger 370 to the hot water discharge pipe 150.
