온수 보일러{Hot water boiler}Hot water boiler

본 발명은 온수 보일러에 관한 것이며, 상세하게는 간접 가열식 난방 및 급탕용 온수 보일러에서 난방 또는 급탕용 온수의 생성을 사용량에 부합시켜 조절할 수 있도록 한 온수 보일러에 관한 것이다.The present invention relates to a hot water boiler, and more particularly, to a hot water boiler in which the generation of hot water for heating or hot water supply can be adjusted according to the usage amount in an indirect heating type heating and hot water boiler for hot water supply.

주지하는 바와 같이, 간접 가열식 온수 보일러는 열매체를 채운 보일러 통체의 상부에 난방용 및 급탕용 열교환기를 각각 내장하여 난방용과 급탕용 온수를 각각 별도로 생성토록 한 것이다.As is well known, the indirect heating type hot water boiler is configured to separately generate hot water for heating and hot water supply by embedding heat exchangers for heating and hot water supply respectively in the upper part of the boiler cylinder filled with heating medium.

그러나 상기한 간접 가열식 온수 보일러는 난방용 열교환기 및 급탕용 열교환기에서 각각 난방용과 급탕용 온수를 별도로 생성할 수 있도록 되어 있기 때문에 계절 요인 또는 사용장소 등에 따라 어느 하나의 온수만을 생성할 경우 1개의 열교환기의 가동은 정지되기 때문에 열효율의 저하가 발생하고 있다.However, in the indirect heating type hot water boiler described above, since hot water for heating and hot water for hot water supply can be separately generated from the heat exchanger for heating and the heat exchanger for hot water supply, respectively, when only one hot water is generated depending on the seasonal factor or the place of use, one heat exchange Since the operation of the machine is stopped, a decrease in thermal efficiency is occurring.

그리고 계절적 요인 등에 따라 난방용 온수와 급탕용 온수의 수요량에 현격한 과잉 또는 부족 문제가 발생되고 있는바, 상기한 난방용 온수 또는 급탕용 온수 중 어느 하나의 수요량이 부족하면 사용온도가 낮아짐으로써 쾌적한 난방이 되지 못하거나 급탕에 불편을 초래하게 되고 열효율이 저하되며, 또한 상기와 같이 난방용 온수와 급탕용 온수의 수요량에 현격한 과부족이 발생하면 열교환기의 부하량도 차이가 발생하기 때문에 각 열교환기의 피로강도에 차이가 있게 되어 수명도 단축되는 문제점이 발생하는 것이다.In addition, depending on seasonal factors, etc., there is a marked excess or shortage problem in the demand for hot water for heating and hot water for hot water supply. Failure to do so or it causes inconvenience to hot water supply and thermal efficiency is lowered. Also, if there is a marked excess or deficiency in the demand for hot water for heating and hot water for hot water supply, as described above, the load amount of the heat exchanger is also different, so the fatigue strength of each heat exchanger There is a difference, and the problem of shortening the lifespan occurs.

상기한 난방용 온수와 급탕용 온수의 사용량에 현격한 과부족이 발생하여 수요가 부족한 온수의 공급을 원활하게 하기 위하여서는 별도의 온수 보일러를 추가 설치하여야 하는 경우도 발생하며, 이러한 경우에는 설치장소 및 비용 문제가 추가로 발생하고 있다.There are cases in which a separate hot water boiler must be additionally installed in order to smoothly supply hot water that is in short supply due to a marked excess and deficiency in the amount of hot water for heating and hot water for hot water supply. In this case, the installation location and cost An additional problem is occurring.

본 발명은 상기한 문제점을 시정하여, 기존의 난방용 및 급탕용 열교환기의 가열유로를 변경하고, 난방용 및 급탕용 급수관과 온 수배출관의 유로를 전환하여서 항상 모든 열교환기를 가동하여 열효율을 상승시키고, 계절요인 등에도 불구하고 항상 수요량을 충족할 수 있는 난방용 및/또는 급탕용 온수를 생성할 수 있는 온수 보일러를 제공하는 것을 목적으로 한다.The present invention corrects the above problems, changes the heating flow path of the existing heat exchanger for heating and hot water supply, and switches the flow paths of the water supply pipe for heating and hot water supply and the hot water discharge pipe to always operate all heat exchangers to increase thermal efficiency, An object of the present invention is to provide a hot water boiler capable of generating hot water for heating and/or hot water supply that can always meet demand despite seasonal factors.

상기한 목적을 달성하기 위하여, 본 발명은 열매체를 채운 보일러 통체와; 상기 보일러 통체의 상부에 내장한 난방용 및 급탕용 열교환기를 구비한 간접 가열식 온수 보일러에 있어서, 상기 각 열교환기의 열교환관의 입구와 출구에 연결한 헤더를 십자(+) 형으로 분할하여 하부 및 상부 양측에 형성한 제1 내지 제4급수실 및 제1 내지 제4온수배출실과; 상기 제1 내지 제4급수실에 각각 연결한 제1 내지 제4급수관 및 제1 내지 제4온수배출실에 각각 연결한 제1 내지 제4온수배출관과; 상기 제1 내지 제4급수관에 상호 연통되게 급수관용 제어밸브들을 부설한 바이패스도관을 연결하여 난방용 열교환기와 급탕용 열교환기에 공급되는 급수의 유로를 난방용 급수와 급탕용 급수 중에서 선택하고, 제1 내지 제4온수배출관에 상호 연통되게 온수배출관용 제어밸브 부설 바이패스도관을 연결하여 난방용 열교환기와 급탕용 열교환기에서 배출되는 온수의 유로를 난방 사용처와 급탕 사용처로 선택할 수 있는 유로전환수단을; 포함한 것이다.In order to achieve the above object, the present invention is a boiler barrel filled with a heating medium; In the indirect heating type hot water boiler having a heat exchanger for heating and hot water supply built in the upper part of the boiler body, the header connected to the inlet and the outlet of the heat exchange tube of each heat exchanger is divided into a cross (+) shape to form a lower part and an upper part first to fourth water supply chambers and first to fourth hot water discharge chambers formed on both sides; first to fourth water supply pipes respectively connected to the first to fourth water supply chambers and first to fourth hot water discharge pipes respectively connected to the first to fourth hot water discharge chambers; The first to fourth water supply pipes are connected to a bypass conduit having control valves installed to communicate with each other to select a flow path of water supply supplied to the heat exchanger for heating and the heat exchanger for hot water supply from among water supply for heating and water for hot water supply, and the first to a flow path switching means for connecting the bypass conduit installed with the control valve for the hot water discharge pipe to the fourth hot water discharge pipe and selecting the flow path of the hot water discharged from the heating heat exchanger and the hot water supply heat exchanger as a heating and hot water supply usage; will include

It can satisfy the needs of hot water users.

또한, 급수가 열교환기에서 가열될 때 모든 열교환관을 흐르면서 균일하게 가열되므로 열흡수율이 증대되어 열효율이 상승 되는 것이다.In addition, when the feed water is heated in the heat exchanger, it is uniformly heated while flowing through all the heat exchange tubes, so that the heat absorption rate is increased and the thermal efficiency is increased.

그리고 열교환기의 부하량도 항상 균일하게 유지할 수 있으므로 양 열교환기의 피로강도를 균등하게 유지하여 수명 단축을 방지할 수 있고, 또한, 종래 별도의 온수 보일러를 부설하던 문제점을 개선함으로서 설치장소 및 비용문제도 해결할 수 있는 것이다.In addition, since the load amount of the heat exchanger can always be maintained uniformly, the fatigue strength of both heat exchangers can be equally maintained to prevent shortening of the life span, and the problem of installing a separate hot water boiler can be improved by improving the installation location and cost problems. can also be solved.
