Description
본 발명은 보일러에 관한 것으로, 구체적으로는 질소가스 충진탱크와 열교환기를 일체로 구비한 보일러에 관한 것이다.The present invention relates to a boiler, and more particularly, to a boiler having a nitrogen gas filling tank and a heat exchanger integrally.
가정용 보일러는 대기와 차단된 압력식 팽창탱크를 구비하여 난방배관이 팽창탱크보다 높은 상행배관의 경우에도 물이 넘치지 않는 구조를 채택하고 있다. 즉, 보일러가 가동되어 배관 내부의 수온이 높아져 부피가 증가하게 되면 배관 내의 압력이 증가하고, 이를 팽창탱크 내부의 격막과 질소충진부가 흡수하게 된다. The domestic boiler is equipped with a pressure expansion tank that is cut off from the atmosphere, so that even if the heating pipe is higher than the expansion tank, the water boiler does not overflow. That is, when the boiler is operated to increase the water temperature in the pipe and increase the volume, the pressure in the pipe increases, and the diaphragm and the nitrogen filling part in the expansion tank are absorbed.
따라서, 대기와 차단된 구조로 인하여 배관 내의 용존 산소량이 감소하여 열교환기 및 배관이 부식이 방지되고 내구성이 증가되는 장점을 갖는다. Therefore, the amount of dissolved oxygen in the pipe is reduced due to the structure blocked from the atmosphere, and the heat exchanger and the pipe have the advantage of preventing corrosion and increasing durability.
그러나, 이러한 종래 가정용 보일러는 질소가 충진된 압력식 팽창탱크와 열교환기가 별도로 구비되므로 제조단가가 상승하는 단점이 있다. However, such a conventional domestic boiler has a disadvantage in that the manufacturing cost is increased because the nitrogen-filled pressure expansion tank and the heat exchanger are separately provided.
또한, 종래 가정용 보일러는 온수를 사용하기 위해 사용자가 온수 수전을 틀더라도 곧바로 더운 물이 나오지 않는 불편함이 있다.In addition, the conventional household boiler is inconvenient that hot water does not come out immediately even if the user turns on the hot water faucet to use hot water.

도1은 본 발명에 따른 보일러(100)의 내부 단면구조를 개략적으로 도시한 개략도이고, 도2는 본 발명에 따른 보일러(100)가 적용된 보일러시스템(1)의 개략적인 구성을 도시한 개략도이다.1 is a schematic diagram showing an internal cross-sectional structure of a boiler 100 according to the present invention, and FIG. 2 is a schematic diagram showing a schematic configuration of a boiler system 1 to which a boiler 100 according to the present invention is applied. .
도시된 바와 같이 본 발명에 따른 보일러(100)는 케이싱(110)과, 케이싱(110)의 하부영역에 배치된 질소충진탱크(120)와, 질소충진탱크(120) 내부에 구비되어 온수의 유출입에 따라 체적이 탄성적으로 변형되는 탄성주머니(130)와, 케이싱(110)의 상부영역에 배치되어 온수의 온도를 조절하는 온수열교환기(140)를 포함한다.As shown, the boiler 100 according to the present invention is provided in the casing 110, the nitrogen filling tank 120 disposed in the lower region of the casing 110, and the nitrogen filling tank 120 to flow in and out of hot water. According to the present invention, a volume of the elastic bag 130 is elastically deformed, and a hot water heat exchanger 140 disposed in the upper region of the casing 110 to adjust the temperature of the hot water.
케이싱(110)은 내부에 질소충진탱크(120)와 온수열교환기(140)를 수용하는 체적을 가지며 내부에 난방수가 순환할 수 있는 공간을 갖는다. 케이싱(110)에는 난방수가 유입 및 유출되는 난방수유입구(111)와 난방수유출구(113)가 구비된다. 또한, 케이싱(110)에는 질소충진탱크(120) 내부로 질소를 충진할 수 있는 질소충진구(115)가 구비된다.The casing 110 has a volume accommodating the nitrogen filling tank 120 and the hot water heat exchanger 140 therein, and has a space in which the heating water circulates. The casing 110 is provided with a heating water inlet 111 and a heating water outlet 113 through which heating water flows in and out. In addition, the casing 110 is provided with a nitrogen filling port 115 for filling nitrogen into the nitrogen filling tank 120.
질소충진탱크(120)는 케이싱(110)의 내부에 구비되어 온수의 온도변화에 따라 탄성주머니(130)의 체적이 변화되도록 한다. 질소충진탱크(120)는 밀폐식 압력탱크로 구비되며 질소가 1~2bar의 압력으로 충진되어 있다. Nitrogen filling tank 120 is provided in the casing 110 to change the volume of the elastic bag 130 according to the temperature change of the hot water. Nitrogen filling tank 120 is provided with a closed pressure tank and nitrogen is filled at a pressure of 1 ~ 2bar.
탄성주머니(130)는 질소충진탱크(120) 내부에 구비된다. 탄성주머니(130)는 난방수가 유입 및 유출될 수 있도록 유입구가 케이싱(110) 내부에 개방된 상태로 구비된다. 탄성주머니(130)는 난방수가 케이싱(110) 내부로 보충되어 수위가 상승되면 내부에 난방수를 수용하여 팽창하고, 난방수가 줄어들면 주변의 질소의 압력으로 인해 탄성적으로 형태가 축소된다. 탄성주머니(130)는 고무재질의 풍선형태로 구비된다. Elastic bag 130 is provided inside the nitrogen filling tank (120). The elastic pouch 130 is provided with an inlet open in the casing 110 to allow the heating water to flow in and out. The elastic pouch 130 is heated to the inside of the casing 110, and the water level is increased when the water level is increased to accommodate the heating water therein, and when the heating water is reduced, the shape is elastically reduced due to the pressure of the surrounding nitrogen. The elastic pocket 130 is provided in the form of a balloon of rubber material.
탄성주머니(130)는 보일러(100)가 가동하면서 난방수의 온도가 올라가서 부피팽창을 할 때에 그 팽창한 량이 내부에 수용되게 된다. 반면, 난방수의 온도가 떨어져서 난방수의 부피가 줄어들면 다시 탄성주머니(130) 외측으로 팽창되었던 난방수가 빠져 나가게 된다. 탄성주머니(130)는 보일러(100)의 가동시 이러한 팽창과 수축을 계속해서 반복한다.The elastic pouch 130 is accommodated therein when the boiler 100 is operated and the temperature of the heating water rises to make the volume expand. On the other hand, when the temperature of the heating water drops and the volume of the heating water decreases, the heating water that has been expanded to the outside of the elastic bag 130 is released. The elastic pouch 130 repeatedly repeats such expansion and contraction during operation of the boiler 100.
열교환기(140)는 난방수가 보유한 열을 온수와 교환하여 케이싱(110) 내부로 유입된 냉수의 온도를 상승시킨다. 본 발명에 따른 열교환기(140)는 열교환 효율을 높이기 위해 나선형으로 감긴 코일형태로 구비된다. 열교환기(140)의 일단부(141)를 통해 냉수가 유입되고, 열교환기(140)의 타단부(143)를 통해 난방수와 열교환을 통해 온도가 상승된 온수가 유출된다.The heat exchanger 140 exchanges heat retained by the heating water with hot water to increase the temperature of the cold water introduced into the casing 110. Heat exchanger 140 according to the present invention is provided in the form of a coil wound in a spiral to increase the heat exchange efficiency. Cold water flows in through one end 141 of the heat exchanger 140, and hot water whose temperature rises through heat exchange with the heating water flows out through the other end 143 of the heat exchanger 140.
이 때, 도2에 도시된 바와 같이 순환펌프(300)를 통해 난방수를 강제로 열교환기(140) 주변으로 강제로 순환시키게 되므로 열교환기(140) 주면에 강제적인 와류구조가 형성될 수 있다. 이에 의해 온수와 난방수의 열교환 효율이 극대화될 수 있다. In this case, as shown in FIG. 2, since the heating water is forced to circulate around the heat exchanger 140 through the circulation pump 300, a forced vortex structure may be formed on the main surface of the heat exchanger 140. . As a result, heat exchange efficiency of hot water and heating water may be maximized.
이러한 구성을 갖는 본 발명에 따른 보일러(100)의 동작과정을 도1과 도2를 참조하여 설명한다. 보일러시스템(1)이 가동되면 주열교환기(140)에 의해 가열된 난방수는 케이싱(110)의 난방수유입구(111)로 유입된다. 가열된 난방수가 케이싱(110) 내부로 유입되어 수위가 점차 높아지면 탄성주머니(130) 내부로 유입되게 된다. The operation of the boiler 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 and 2. When the boiler system 1 is operated, the heating water heated by the main heat exchanger 140 flows into the heating water inlet 111 of the casing 110. When the heated water is introduced into the casing 110 and the water level is gradually increased, the heated water is introduced into the elastic bag 130.
탄성주머니(130)로 난방수가 유입되고 난방수의 온도가 점차 상승하면 난방수의 부피팽창으로 인해 탄성주머니는 도1에 도시된 바와 같이 줄어든 상태에서 도2에 도시된 바와 같이 탄성적으로 팽창하게 된다. When the heating water flows into the elastic bag 130 and the temperature of the heating water gradually rises, the elastic bag expands elastically as shown in FIG. 2 in a reduced state as shown in FIG. 1 due to the volume expansion of the heating water. do.
난방수는 난방수유출구(113)를 통해 유출되고 순환펌프(300)와 삼방밸브(400)를 거쳐 라디에이터 또는 난방처(500)로 공급된다. The heating water flows out through the heating water outlet 113 and is supplied to the radiator or the heating destination 500 through the circulation pump 300 and the three-way valve 400.
