Description
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 태양열보일러와 가스보일러를 가동시켜 에너지효율을 증대시킨 태양열보일러시스템에 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, and more particularly, detects a temperature, a solar collector temperature, a heating water temperature, and the like of each solar heat storage tank by a sensor. The present invention relates to a solar boiler system that increases energy efficiency by operating a solar boiler 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 야기시키지 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.
본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 센서에 의해 태양열 축열조 각 부의 온도, 태양열집열기 온도, 난방수 온도 등을 감지하고 태양열집열기 및 가스보일러와 연결된 열교환코일을 축열조 내부에 각각 설치하여, 난방열원으로 가스보일러를 사용함과 아울러 온수가열 열원으로 태양열을 사용하되 센서에 감지된 각 부분의 온도에 따라 필요시 온수가열의 보조열원으로 가스보일러를 이용하도록 된 태양열보일러시스템을 제공하는 것을 목적으로 한다.The present invention has been invented to solve the above problems, the sensor detects the temperature of each part of the solar heat storage tank, the temperature of the solar heat collector, the heating water temperature and the like, and installed heat exchange coils connected to the solar heat collector and the gas boiler inside the heat storage tank, respectively. By using a gas boiler as a heating heat source and using solar heat as a hot water heating source, according to the temperature of each part detected by the sensor, providing a solar boiler system that uses a gas boiler as an auxiliary heat source for hot water heating if necessary.

Until the circulation of hot water is made, heat exchange between the water stored in the heat storage tank 100 and the hot water heated in the solar collector 200 is performed. In this case, the temperature deviation may vary according to the user's setting.
한편, 상기 온도센서(610)의 온도가 사용자가 설정한 온도보다 높으면, 가스보일러(300)의 버너(310)에서 가열된 온수는 상기 축열조(200)로 유입되지 않고 외부에 설치된 난방부하(500)쪽으로만 순환된다. 이때, 상기 가스보일러(300)는 난방부하(500)에 난방수를 공급할 필요가 없는 경우에는 작동되지 않는다.On the other hand, if the temperature of the temperature sensor 610 is higher than the temperature set by the user, hot water heated in the burner 310 of the gas boiler 300 does not flow into the heat storage tank 200, the heating load 500 is installed outside Only cycles toward). In this case, the gas boiler 300 does not operate when it is not necessary to supply heating water to the heating load 500.
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 is a view illustrating a heating water heating circulation diagram according to an embodiment of the present invention, wherein the hot water temperature of the heat storage tank 100 received by the solar controller 510-the temperature measured by the temperature sensor 620-is the heating load. The hot water flow in the case where the temperature of the hot water circulated through the 500 and discharged-the temperature measured by the temperature sensor 630-is higher.
이 경우 상기 태양열콘트롤러(510)는 전기신호를 통해 난방배관(340)에 설치결합된 삼방밸브(350)를 상기 축열조(100)의 제2열교환코일(120)과 연결된 입구관(170)으로 개방시키고 입구관(170)에 설치된 삼방밸브(470)를 제2열교환코일(120)방향으로 개방시킴과 아울러 펌프(460)를 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 순환되도록 한다.In this case, the solar controller 510 opens the three-way valve 350 installed on the heating pipe 340 through the electric signal to the inlet pipe 170 connected to the second heat exchange coil 120 of the heat storage tank 100. And open the three-way valve 470 installed in the inlet pipe 170 in the direction of the second heat exchange coil 120 and operate the pump 460 to remove hot water from the heating load 500. While circulating the heat exchange coil 120 to absorb the heat stored in the heat storage tank 100 to be circulated back to the heat exchanger 320 of the gas boiler (300).
상기 온수의 순환은 제2열교환코일(120)부근에 설치된 온도센서(620)에서 측정된 온도와 난방배관(340)에 설치된 온도센서(630)에서 측정된 온도가 같아질 때까지 행해진다.The circulation of the hot water is performed until the temperature measured by the temperature sensor 620 installed near the second heat exchange coil 120 is equal to the temperature measured by the temperature sensor 630 installed in the heating pipe 340.
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 4는 본 발명의 일실시예에 따른 급탕가열 순환도를 도시한 것으로서, 태양열집열기(200) 및 축열조(100)의 온도를 측정하는 온도센서(610)의 온도가 사용자가 온수로 사용하기에 부적합한 경우에는, 난방배관(340)에 설치된 삼방밸브(360)가 입구관(170)쪽으로 개방되고 입구관(170)에 설치된 삼방밸브(470)가 제3열교환코일(130)쪽으로만 개방되어, 가스보일러(300)의 열교환기(320)에서 가열된 고온의 온수가 제3열교환코일(130)쪽으로만 순환된다.Figure 4 shows the hot water heating circulation according to an embodiment of the present invention, the temperature of the temperature sensor 610 for measuring the temperature of the solar collector 200 and the heat storage tank 100 for the user to use hot water If it is not suitable, the three-way valve 360 installed in the heating pipe 340 is opened toward the inlet pipe 170 and the three-way valve 470 installed in the inlet pipe 170 opens only toward the third heat exchange coil 130, The high temperature hot water heated in the heat exchanger 320 of the gas boiler 300 is circulated only to the third heat exchange coil 130.
따라서, 상기 가스보일러(300)의 열교환기(320)에서 가열된 난방수가 상기 삼방밸브(360), 입구관(170) 및 삼방밸브(470)를 거쳐 상기 제3열교환코일(130)를 지난 후 다시 열교환기(320)로 되돌아오는 짧은 순환구조를 가지므로, 단시간에 상기 축열조(100) 상부에 저장된 물을 설정온도까지 가열시켜 사용자에게 온수를 제공할 수 있는 장점이 있다.Therefore, after the heating water heated in the heat exchanger 320 of the gas boiler 300 passes the third heat exchange coil 130 through the three-way valve 360, the inlet pipe 170, and the three-way valve 470. Since it has a short circulation structure back to the heat exchanger 320, there is an advantage that can provide hot water to the user by heating the water stored above the heat storage tank 100 to a set temperature in a short time.
한편, 상기 가스보일러(300)는 상기 축열조(100) 상부에 설치된 저수위센서(160)가 축열조(100) 내부의 온수부족을 감지한 경우와 유량흐름스위치(141)에서 직수의 흐름이 감지되지 않는 경우에는 온수가 온수배출관(150)을 통해 외부로 배출되지 않고 있는 경우이므로 작동되지 않는다.On the other hand, the gas boiler 300 is a case where the low water level sensor 160 installed on the heat storage tank 100 detects the lack of hot water in the heat storage tank 100 and the flow of direct water is not detected in the flow flow switch 141. If the hot water is not discharged to the outside through the hot water discharge pipe 150 is not operated.
다만, 유량흐름스위치(141)에서 직수의 흐름이 감지되지 않는 경우에 있어서는, 상기 축열조(100)의 온수온도가 설정온도까지 상승한 후 자연방열에 의해 온도가 허용범위이내로 떨어진 경우에 한한다. 따라서, 상기 유량흐름스위치(141)를 통해 직수가 유동되지 않는 경우에도 축열조(100) 내부의 온도가 허용범위를 벗어난경우에는 상기 가스보일러(300)가 작동된다.However, in the case where the flow of the direct water is not detected in the flow rate switch 141, the temperature of the heat storage tank 100 is increased to the set temperature, and only after the temperature falls within the allowable range by natural heat radiation. Therefore, even when direct water does not flow through the flow rate switch 141, when the temperature inside the heat storage tank 100 is outside the allowable range, the gas boiler 300 is operated.
이상에서 설명한 바와 같이 본 발명 태양열보일러시스템에 의하면, 태양열을 최대한 이용하면서 가스보일러를 적절한 시기에 사용하므로 대용량의 태양열집열기가 필요하지 않으며, 태양열집열기, 축열조 및 가스보일러에 설치된 온도센서에 따른 삼방밸브의 작동에 따라 온수순환과 난방순환을 하므로 에너지절감효과를 극대화할 수 있는 효과가 있다.As described above, according to the solar boiler system of the present invention, since the gas boiler is used at the appropriate time while maximizing solar heat, a large capacity solar collector is not required, and the three-way valve according to the temperature sensor installed in the solar collector, the heat storage tank, and the gas boiler is used. According to the operation of the hot water circulation and heating circulation, there is an effect that can maximize the energy saving effect.
