Description

난방용수가열관을 사용한 태양열 난방 시스템{WATER HEATING PIPE INSTALLED SOLAR HEATED SYSTEM}Solar heating system using heating water pipes {WATER HEATING PIPE INSTALLED SOLAR HEATED SYSTEM}

본 발명은 태양열에 의해 가열된 용수를 사용하여 난방을 하는 난방시스템에 관한 것이다. 특히 태양열에 의해 가열된 용수와 난방영역을 순환하는 용수가 간접적으로 열교환을 하도록 하기 위해 별도의 난방용수관을 설치한 것에 특징이 있다.The present invention relates to a heating system for heating using water heated by solar heat. In particular, it is characterized in that a separate heating water pipe is installed in order to indirectly heat exchange with the water heated by solar heat and the water circulating in the heating area.

종래의 태양열 난방시스템은 태양열에 의해 가열된 용수를 저장한 용수저장탱크로부터 저장된 용수를 직접 뽑아서 난방영역으로 공급하는 것으로서, 난방영역에서 난방을 마치고 온도가 떨어진 용수가 직접 용수저장탱크로 유입되는 방식의 것이었다.Conventional solar heating system draws water directly from the water storage tank that stores the water heated by solar heat and supplies it to the heating zone. After heating in the heating zone, the water is dropped into the water storage tank. Was.

그러나 난방을 위해 용수저장탱크에 저장된 용수를 직접 뽑아서 사용할 경우, 뽑아낸 용수의 양만큼 난방을 마치고 냉각된 용수가 직접 용수저장탱크로 유입된다. 용수저장탱크에 저장된 용수의 온도는 여름에는 섭씨 100도 이상까지 상승하며, 겨울에는 섭씨 65~75도 까지 상승한다. 따라서 용수저장탱크내 저장된 용수의 온도를 섭씨 70 내지 80도라 가정할 경우, 용수저장탱크에서 직접 뽑아낸 용수의 온도는 70~80도 정도이며, 난방을 마치고 용수저장탱크로 유입되는 용수의 온도는 40~50도 이하가 된다. 따라서 용수저장탱크에 저장된 용수의 온도는 급속하게 하강한다. 용수저장탱크에 저장된 용수의 온도가 섭씨 50도 이하로 떨어지면 용수저장탱크에 저장된 용수는 온도가 낮아 더이상 난방용수로 사용하기에 부적합하다.However, when the water stored in the water storage tank is directly extracted and used for heating, the cooled water is directly flowed into the water storage tank after the heating by the amount of the extracted water. The temperature of the water stored in the water storage tanks rises to over 100 degrees Celsius in summer and to 65-75 degrees Celsius in winter. Therefore, assuming that the temperature of the water stored in the water storage tank is 70 to 80 degrees Celsius, the temperature of the water directly extracted from the water storage tank is about 70 to 80 degrees, and the temperature of the water flowing into the water storage tank after the heating is It becomes 40-50 degrees or less. Therefore, the temperature of the water stored in the water storage tank drops rapidly. If the temperature of the water stored in the water storage tank drops below 50 degrees Celsius, the water stored in the water storage tank is cold and is no longer suitable for use as heating water.

이렇게 용수저장탱크에 저장된 용수를 직접 뽑아서 난방을 하는 경우에는 용수저장탱크에 저장된 용수의 온도가 상대적으로 빨리 떨어져 난방을 위해 사용하기에 부적합한 온도에 도달하므로, 결국 난방 가능 시간이 단축되는 문제가 있다.In this case, when the water stored in the water storage tank is directly drawn and heated, the temperature of the water stored in the water storage tank drops relatively quickly, thus reaching an unsuitable temperature for heating, thus shortening the heating time. .

태양이 떠있는 주간에는 집열부에서 계속하여 용수를 가열하므로, 용수저장탱크에 저장된 용수의 온도가 떨어져도 이를 다시 상승시키게 된다. 그러나 야간에는 태양으로부터 집열을 할 수 없기 때문에 용수저장탱크에 저장된 용수의 온도가 떨어져도 이를 다시 상승시키지 못한다. 따라서 특히 야간에 용수저장탱크에 저장된 용수의 온도가 하강하는 것을 최소화할 필요성이 커진다.During the day when the sun is floating, the water is continuously heated in the collector, so that the temperature of the water stored in the water storage tank drops again. At night, however, it cannot collect heat from the sun, so it does not rise again when the temperature of the water stored in the water storage tank drops. Therefore, there is a great need to minimize the drop in temperature of the water stored in the water storage tank, especially at night.

본 발명은 태양열 난방시스템에 있어서, 용수저장탱크로부터 난방을 위해 직접 저장된 용수를 뽑아사용하지 않고 용수저장탱크를 통과하는 난방용수가열관을 통해 저장용수와 난방영역을 순환하는 용수들 사이에 간접적인 열교환을 하도록 함으로써, 용수저장탱크내 저장된 용수의 단위시간당 온도감소량을 작게 하여 그 결과 난방가능시간을 증가시키고자 한다.In the present invention, in the solar heating system, an indirect connection between storage water and water circulating in a heating zone through a heating water heating tube passing through the water storage tank without using the water stored directly for heating from the water storage tank is used. By performing the heat exchange, the temperature decrease per unit time of the water stored in the water storage tank is made small, and as a result, the heating time can be increased.

상기한 바와 같은 본 발명의 과제는 태양광으로부터 열을 흡수하는 집열부와 내부에 용수를 저장할 공간이 구비되고 상기 집열부로 상기 용수를 순환시키기 위해 상기 집열부와 연결되는 용수저장탱크 및 난방영역으로 공급되는 난방용수를 가열하기 위해 상기 용수저장탱크의 내부공간을 통과하도록 설치되는 난방용수가열관을 포함하는 난방용수가열관을 사용한 태양열 난방시스템에 의해 해결된다.An object of the present invention as described above is a water storage tank and a heating area having a heat collecting portion for absorbing heat from sunlight and a space for storing water therein and connected to the heat collecting portion for circulating the water to the heat collecting portion. It is solved by a solar heating system using a heating water heating tube including a heating water heating tube installed to pass through an internal space of the water storage tank to heat the heating water supplied to the water.

또한 상기 과제를 해결하기 위해, 상기 난방용수가열관은 일단으로 난방용수가 유입되고 타단으로 상기 유입된 난방용수가 배출되는 것이 바람직하다.In addition, in order to solve the above problems, it is preferable that the heating water is introduced into the heating water heating tube to one end and the introduced heating water is discharged to the other end.

또한 상기 과제를 해결하기 위해, 상기 난방용수가열관은 상기 용수저장탱크에 저장될 용수의 수면보다 아래에 위치하도록 상기 용수저장탱크 내부에 설치되는 것이 바람직하다.In addition, in order to solve the above problems, the heating water heating pipe is preferably installed in the water storage tank so as to be located below the water surface of the water to be stored in the water storage tank.

또한 상기 과제를 해결하기 위해, 상기 난방용수가열관은 코일상으로 감겨지는 것이 바람직하다.In addition, in order to solve the above problems, it is preferable that the heating water heating tube is wound in a coil shape.

또한 상기 과제를 해결하기 위해, 용수저장탱크의 상부에는 상기 용수저장탱크의 내부와 연통되는 보조탱크가 더 형성되는 것이 바람직하다.In addition, in order to solve the above problems, it is preferable that an auxiliary tank communicating with the inside of the water storage tank is further formed on the upper portion of the water storage tank.

또한 상기 과제를 해결하기 위해, 용수저장탱크에는 온수로 사용되는 용수를 가열하기 위해 상기 용수저장탱크의 내부공간을 통과하도록 설치되며 온수배출관에 연결되는 온수가열관이 더 형성된 것이 바람직하다.In addition, in order to solve the above problems, the water storage tank is preferably installed to pass through the inner space of the water storage tank to heat the water used as hot water and is further formed with a hot water heating tube connected to the hot water discharge pipe.

본 발명에 따른 난방용수가열관을 사용한 태양열 난방시스템은 용수저장탱크를 통과하는 난방용수가열관을 통해 탱크 내부의 용수와 난방용수가열관 내부의 용수들 사이에 간접적인 열교환을 하도록 함으로써, 용수저장탱크내 저장된 용수의 단위시간당 온도감소량을 작게 하여 그 결과 난방가능시간을 증가시키는 효과가 있다.Solar heating system using a heating water heating tube according to the present invention by indirect heat exchange between the water in the tank and the water in the heating water heating tube through the heating water heating tube passing through the water storage tank, water storage The temperature decrease per unit time of the water stored in the tank is made small, and as a result, the heating time can be increased.

또한 난방용수가열관은 용수저장탱크에 저장된 용수의 수면보다 낮은 위치에 형성되기 때문에 난방용수가열관에서 배출되는 난방용수의 압력이 감소되어, 그 결과 보일러 내부의 난방용수를 저장하는 탱크에 작용하는 압력을 감소시켜 탱크의 파손을 방지할 수 있다. 태양열 난방시스템의 경우 대용량의 용수저장탱크를 필요로 하기 때문에 이러한 용수저장탱크는 옥상 등 높은 곳에 설치하는 것이 일반적이며 이때 용수저장탱크와 보일러 사이의 높이차이 때문에 보일러로 유입하는 난방용수의 압력이 커서 보일러 내부의 탱크가 파손되거나 손상되기 쉽다.In addition, since the heating water heating tube is formed at a lower position than the water level stored in the water storage tank, the pressure of the heating water discharged from the heating water heating tube is reduced, and as a result, the heating water inside the boiler acts on the tank for storing the heating water. The pressure can be reduced to prevent damage to the tank. In the case of solar heating system, a large capacity water storage tank is required. Therefore, such a water storage tank is generally installed in a high place such as a rooftop. In this case, the pressure of the heating water flowing into the boiler is large due to the height difference between the water storage tank and the boiler. The tank inside the boiler is easily damaged or damaged.

또한 난방을 거친 용수는 난방용수가열관을 통해서 용수저장탱크에 저장된 용수와 간적적인 열교환을 하므로, 용수저장탱크 내부로 난방호스를 거친 난방용수 가 직접 회수되는 것이 비해 용수저장탱크 내부에 스케일이 누적되는 것이 현저히 줄어든다.In addition, the heated water is intermittently exchanged with the water stored in the water storage tank through the heating water heating tube, so that the scale accumulates inside the water storage tank, as compared with the heating water directly recovered through the heating hose into the water storage tank. To be significantly reduced.

도 2는 본 발명에 따른 난방용수가열관을 사용한 태양열 난방시스템의 용수저장탱크의 구성을 개략적으로 도시한 도면이고, 도 3은 종래의 태양열 난방시스템의 용수저장탱크의 구성을 개략적으로 도시한 도면이다. 도 2에 도시된 바와 같이, 본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템은 난방용수가열관(30)의 최상단이 보일러(50)로부터 H2의 높이차를 갖는다. 따라서 보일러(50)와 난방용수가열관(30)의 높이차에 의해 기인하는 용수의 압력은 H2에 대응한다. 그러나 용수저장탱크(10)에 저장된 용수의 수면의 높이는 보일러(50)로부터 H1+H2의 높이차를 갖는다. 따라서 용수저장탱크(10)로부터 직접 난방용수를 뽑아서 보일러(50)에 공급하는 경우에는 보일러(50)와 용수저장탱크(10) 사이의 높이차에 의해 기인하는 용수의 압력이 H1+H2에 대응한다. 결국 본 발명에 따른 난방용수가열 관(30)을 사용한 태양열 난방시스템은 용수저장탱크(10) 내부에 별도의 난방용수가열관(30)을 설치하였기 때문에 H1의 높이에 대응하는 용수의 압력이 제거되는 것이다. 따라서 보일러(50)의 용수탱크에 작용하는 용수의 압력이 상당히 감소된다.2 is a view schematically showing a configuration of a water storage tank of a solar heating system using a heating water heating tube according to the present invention, and FIG. 3 is a view schematically showing the configuration of a water storage tank of a conventional solar heating system. to be. As shown in FIG. 2, the solar heating system using the heating water heating tube 30 according to the present invention has a height difference of H 2 from the boiler 50 at the uppermost end of the heating water heating tube 30. Therefore, the pressure of the water caused by the height difference between the boiler 50 and the heating water heating tube 30 corresponds to H2. However, the height of the water surface of the water stored in the water storage tank 10 has a height difference of H1 + H2 from the boiler (50). Therefore, when the heating water is directly extracted from the water storage tank 10 and supplied to the boiler 50, the pressure of the water caused by the height difference between the boiler 50 and the water storage tank 10 corresponds to H1 + H2. do. Eventually, the solar heating system using the heating water heating tube 30 according to the present invention has installed a separate heating water heating tube 30 inside the water storage tank 10, so that the pressure of the water corresponding to the height of H1 is removed. Will be. Therefore, the pressure of the water acting on the water tank of the boiler 50 is considerably reduced.

도 3에 도시된 바와 같이, 종래의 태양열 난방시스템의 경우 용수저장탱크(10)로부터 직접 난방용수를 뽑아서 보일러(50)에 공급하기 때문에 보일러(50)와 용수저장탱크(10)에 저장된 용수의 높이차에 의해 기인하는 용수의 압력이 H3=H1+H2에 대응한다. 따라서 보일러(50)의 용수탱크에 작용하는 용수의 압력이 크게 되어 보일러(50) 용수탱크의 파손의 위험이 커진다.As shown in FIG. 3, in the conventional solar heating system, since the heating water is directly extracted from the water storage tank 10 and supplied to the boiler 50, the water stored in the boiler 50 and the water storage tank 10 may be used. The pressure of the water caused by the height difference corresponds to H3 = H1 + H2. Therefore, the pressure of the water acting on the water tank of the boiler 50 is increased, which increases the risk of damage to the water tank of the boiler 50.

도 4는 본 발명에 따른 난방용수가열관을 사용한 태양열 난방시스템에서 난방용수가열관을 사용한 경우와 종래의 태양열 난방 시스템에서 직접 용수를 뽑아쓰는 경우의 온도 저하 원리를 설명하기 위한 도면이다. 도 4에 도시된 바와 같이, 본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템의 경우 난방용수가열관(30)을 매개로 간접적인 열교환을 한다. 그 결과 용수저장탱크(10)로 유입되는 냉각된 용수는 서서히 열을 전달받게 되고, 역으로 용수저장탱크(10)에 저장된 용수는 서서히 열을 빼앗기게 된다. 용수저장탱크(10)에 저장된 용수의 온도가 섭씨 75도일 경우 난방용수가열관(30)에서 배출되는 용수의 온도는 섭씨 65 내지 70도가 된다. 완전한 열평형 상태가 되는데는 장시간이 소요되므로 열평형을 이루지 못한 상태에서 난방용수가 난방용수가열관(30)으로부터 배출되기 때문이다. 또한 용수저장탱크(10)에 저장된 용수에는 외력이 가해지지 않기 때문에, 난방용수가열관(30)에 인접한 부분에서부터 먼 부분까지 거리에 비례하여 용수는 완만한 온도구 배를 이룬다. 이러한 완만한 온도구배는 급격하게 열교환이 이루어지는 것을 방지한다. 따라서 용수저장탱크(10)에 저장된 용수는 난방용수로 열을 서서히 주게 되어 저장된 용수 자체의 온도를 최대한 보존한다. 4 is a view for explaining the principle of temperature reduction in the case of using the heating water heating tube in the solar heating system using the heating water heating tube according to the present invention and the case of directly extracting the water from the conventional solar heating system. As shown in FIG. 4, in the case of a solar heating system using the heating water heating tube 30 according to the present invention, indirect heat exchange is performed through the heating water heating tube 30. As a result, the cooled water flowing into the water storage tank 10 receives heat gradually, and conversely, the water stored in the water storage tank 10 is gradually deprived of heat. When the temperature of the water stored in the water storage tank 10 is 75 degrees Celsius, the temperature of the water discharged from the heating water heating tube 30 is 65 to 70 degrees Celsius. This is because the heating water is discharged from the heating water pipe 30 in the state that the heat balance is not achieved because it takes a long time to be in a complete thermal equilibrium state. In addition, since external force is not applied to the water stored in the water storage tank 10, the water forms a gentle temperature gradient in proportion to the distance from the portion adjacent to the heating water pipe 30 to the far portion. This gentle temperature gradient prevents rapid heat exchange. Therefore, the water stored in the water storage tank 10 is gradually given heat to the heating water to preserve the maximum temperature of the stored water itself.

그러나 용수저장탱크(10)로부터 직접 난방용수를 뽑아쓰는 종래의 태양열 난방시스템의 경우 용수저장탱크(10) 내부로 난방을 마친 냉각된 난방용수가 직접 유입된다. 유입된 저온의 난방용수는 용수저장탱크(10)에 저장된 용수와 곧바로 섞이게 되며 급격한 열교환을 하여 단시간에 열평형을 이룬다. 또한 저온의 난방용수 유입되는 속도에 비례하는 유입 난방용수의 운동량은 용수저장탱크(10)에 저장된 용수에 외력으로 작용하고 이에 따라 용수저장탱크(10)에 저장된 용수는 활발한 유동을 하게 되므로 급격한 열교환을 가속화시킨다. 결론적으로 용수저장탱크(10)로 직접 유입되는 저온의 난방용수에 의해 용수저장탱크(10)에 저장된 용수는 단시간에 열을 빼앗기게 된다. 또한 용수저장탱크(10)로부터 용수를 직접 뽑아서 난방영역으로 공급하기 때문에, 고온의 용수가 보유한 열에너지가 그대로 배출되므로 용수저장탱크(10)에 저장된 용수는 단시간이 열을 빼앗기는 것이다. 일예로서 용수저장탱크(10)에 저장된 용수의 온도가 섭씨 75도일 경우 난방을 위해 배출되는 용수의 온도는 역시 섭씨 75도가 된다. 따라서 본 발명에 따른 태양열 난방시스템과 비교할 때 섭씨 5 내지 10도정도 온도가 높은 용수를 배출하므로 용수저장탱크(10)에 저장된 용수의 온도는 상대적으로 빨리 떨어지게 된다. However, in the conventional solar heating system which draws heating water directly from the water storage tank 10, the cooled heating water which has been heated into the water storage tank 10 is directly introduced. The low temperature heating water introduced is immediately mixed with the water stored in the water storage tank 10 and achieves heat equilibrium in a short time by rapid heat exchange. In addition, the momentum of the inlet heating water proportional to the inflow rate of the low temperature heating water acts as an external force on the water stored in the water storage tank 10, and accordingly, the water stored in the water storage tank 10 has an active flow, thereby rapidly exchanging heat. To accelerate. In conclusion, the water stored in the water storage tank 10 is deprived of heat in a short time by the low temperature heating water flowing directly into the water storage tank 10. In addition, since water is directly extracted from the water storage tank 10 and supplied to the heating area, thermal energy retained by the high temperature water is discharged as it is, so that the water stored in the water storage tank 10 is deprived of heat for a short time. For example, when the temperature of the water stored in the water storage tank 10 is 75 degrees Celsius, the temperature of the water discharged for heating is also 75 degrees Celsius. Therefore, compared with the solar heating system according to the present invention, the temperature of the water stored in the water storage tank 10 falls relatively quickly since the water is discharged at a high temperature of about 5 to 10 degrees Celsius.

일예로 30평 면적을 난방하기 위해 1000리터의 용수를 저장한 용수저장탱크(10)를 사용할 경우 한 번에 순환시키는 난방용수의 양은 100리터 정도가 된다. 용수저장탱크(10)에 저장된 용수의 온도가 섭씨 75도이고 난방에 사용될 수 있는 용수의 최저온도가 섭씨 50도일 경우, 본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템은 약 5시간을 난방할 수 있는데 반해, 종래의 용수를 직접 뽑아쓰는 태양열 난방시스템은 약 4시간을 난방할 수 있다.For example, in the case of using the water storage tank 10 storing 1000 liters of water to heat an area of 30 pyeong, the amount of heating water circulated at a time is about 100 liters. When the temperature of the water stored in the water storage tank 10 is 75 degrees Celsius and the minimum temperature of the water that can be used for heating is 50 degrees Celsius, the solar heating system using the heating water heating tube 30 according to the present invention is about 5 degrees Celsius. While the heat can be heated, conventional solar heating systems that draw water directly can heat about four hours.

이에 더하여 본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템에서 용수저장탱크(10)에 위치하는 구리재질의 난방용수가열관(30) 자체의 온도는 용수저장탱크(10)에 저장된 용수의 온도와 거의 동일하다. 즉 난방용수가열관(30) 자체가 난방용수로 전달할 수 있는 열에너지는 축열하고 있는 것이 된다. 이는 시스템의 난방 가능시간을 연장시키는 효과가 있다.In addition, in the solar heating system using the heating water heating pipe 30 according to the present invention, the temperature of the heating water heating pipe 30 itself of the copper material located in the water storage tank 10 is stored in the water storage tank 10. It is almost equal to the temperature of the water. In other words, the heat energy that can be transferred to the heating water by the heating water heating tube 30 itself becomes heat storage. This has the effect of extending the heatable time of the system.

또한 본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템은 난방을 거친 난방용수가 직접 용수저장탱크(10)로 유입되지 않고 난방용수가열관(30)을 통해서 용수저장탱크(10)를 통과하는 것이므로, 난방용수에 포함된 불순물에 의해 용수저장탱크(10) 내부에 스케일이 누적되는 것을 상당히 감소시키거나 방지할 수 있다.In addition, in the solar heating system using the heating water heating tube 30 according to the present invention, the heating water after heating is not directly introduced into the water storage tank 10, but the water storage tank 10 is heated through the heating water heating tube 30. Since passing through, it is possible to considerably reduce or prevent the accumulation of scale in the water storage tank 10 by impurities contained in the heating water.

본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템에서 난방용수가열관(30)의 위치를 낮게 할수록 난방용수가열관(30)으로부터 배출되어 보일러(50) 용수탱크로 유입되는 난방용수의 압력이 더 감소된다.In the solar heating system using the heating water heating tube 30 according to the present invention, as the position of the heating water heating tube 30 is lowered, the heating water is discharged from the heating water heating tube 30 and flows into the boiler 50 water tank. Pressure is further reduced.

특히 종래의 태양열 난방시스템에서는 용수저장탱크(10)에 저장된 용수의 수면이 보조탱크(20)까지 상승하는 경우 상승된 수면의 높이에 대응하는 압력의 증가량이 그대로 배출용수에 반영되는데 반해, 본 발명에 따른 난방시스템은 용수저장 탱크(10) 내부에 별도의 난방용수가열관(30)이 형성되므로 용수저장탱크(10) 내부의 용수의 압력이 증가해도 보일러(50)로 공급되는 난방용수의 압력이 증가하지 않으므로 보일러(50)의 탱크를 파손시키지 않게 된다.In particular, in the conventional solar heating system, when the water level of the water stored in the water storage tank 10 rises up to the auxiliary tank 20, the increase in pressure corresponding to the elevated water level is reflected in the discharge water as it is. The heating system according to the pressure of the heating water supplied to the boiler 50 even if the pressure of the water in the water storage tank 10 is increased because a separate heating water heating tube 30 is formed in the water storage tank 10. Since this does not increase, the tank of the boiler 50 is not damaged.

본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템은 난방용수를 공급하는 난방용수가열관(30)이 보일러(50)에 연결되는 구성을 설명하였으나, 본 발명은 이에 한정되지 않으며, 난방용수가열관(30)이 보일러(50)를 거치지 않고 난방영역으로 직접 연결되어 난방을 하는 것도 물론 가능하다.The solar heating system using the heating water heating tube 30 according to the present invention has been described a configuration in which the heating water heating tube 30 for supplying heating water is connected to the boiler 50, but the present invention is not limited thereto. The heating water heating pipe 30 is directly connected to the heating area without passing through the boiler 50, and it is also possible to heat the heating water.

본 발명에 따른 난방용수가열관(30)을 사용한 태양열 난방시스템의 실시예에서 구체적인 설명을 하지 않았지만 용수들의 강제적인 이동이 필요한 부분에는 펌프가 설치된다. Although not described in detail in the embodiment of the solar heating system using the heating water heating tube 30 according to the present invention, a pump is installed at a portion requiring forced movement of water.
