본 발명은 온수 보일러에 관한 것이며, 상세하게는 1개의 열교환기에서 난방용 온수와 급탕용 온수를 각각 별도로 생성하거나 어느 하나의 온수만을 생성할 수 있는 간접 가열식 온수 보일러에 관한 것이다.The present invention relates to a hot water boiler, and more particularly, to an indirect heating hot water boiler capable of separately generating hot water for heating and hot water for hot water supply in one heat exchanger or generating only one hot water.

주지하는 바와 같이 제조업 시설, 업무용 건물, 호텔 등에서는 난방용 온수와 급탕용 온수를 각각 필요로 하는 바, 상기 온수를 생성하는 간접 가열식 온수 보일러는 보일러 통체의 상부에 난방용 온수 생성용 열교환기와 급탕용 온수 생성용 열교환기를 각각 내장하여서 난방용 온수와 급탕용 온수를 동시에 생성하거나, 계절적 요인 또는 수요량이 없는 경우에는 난방용 온수와 급탕용 온수 중 어느 하나의 온수만을 선택적으로 생성하고 있다.As is well known, manufacturing facilities, business buildings, hotels, etc. each require hot water for heating and hot water for hot water supply.

그러나 상기한 보일러 통체에 난방용 열교환기와 급탕용 열교환기를 각각 내장할 경우 즉 2개의 열교환기를 내장할 경우, 첫째, 보일러 통체의 부피가 커지고 설치면적도 증가 됨과 아울러 열교환기의 제조비용이 많이 소요되어 비경제적이고,However, when a heat exchanger for heating and a heat exchanger for hot water supply are respectively built in the boiler body, that is, when two heat exchangers are built in, first, the volume of the boiler body increases, the installation area increases, and the manufacturing cost of the heat exchanger is high, which is uneconomical. enemy,

둘째, 난방용 온수와 급탕용 온수는 계절적 요인, 사용장소 등에 따라 어느 하나의 온수만을 생성할 경우 어느 하나의 열교환기는 가동을 중단하여야 하므로 보일러 효율의 저하가 발생하며,Second, when only one type of hot water for heating and hot water for hot water supply is generated depending on seasonal factors and places of use, one of the heat exchangers must be stopped, resulting in a decrease in boiler efficiency.

셋째, 계절적 요인 등에 따라 그 수요량(사용량)에 현격한 차이가 발생하는 바, 각 열교환기의 온수 생성량은 그 최대 생성량이 설계적으로 정하여 짐으로써 최대 생성량이 최대 수요량 보다 작을 경우 사용량 부족 현상을 초래하며,Third, there is a marked difference in the demand (usage) depending on seasonal factors, etc. As the maximum amount of hot water generated by each heat exchanger is determined by design, if the maximum amount is less than the maximum demand, it causes a shortage of usage. and

넷째, 상기와 같이 어느 하나의 열교환기의 가동을 중단할 때 양 열교환기의 피로강도가 상이하여 수명에 차이가 발생하여 어느 하나의 열교환기만을 교환하여야 하기 때문에 번잡하고 비경제적인 문제점 등이 있는 것이다.Fourth, when stopping the operation of any one heat exchanger as described above, the fatigue strength of both heat exchangers is different, which causes a difference in lifespan, so that only one heat exchanger has to be replaced, which is complicated and uneconomical. .

본 발명은 상기한 문제점 등을 시정하여, 보일러 통체를 컴팩트 하게 하고, 1개의 열교환기에서 난방용 및 급탕용 온수의 생성을 동시에 하거나 어느 하나의 온수만을 선택적으로 생성하여 수요량에 부응토록하며, 열효율을 상승함과 아울러 수명을 균일하게 유지할 수 있는 온수 보일러를 제공하는 것을 목적으로 한다.The present invention corrects the above problems, makes the boiler barrel compact, generates hot water for heating and hot water supply at the same time in one heat exchanger, or selectively generates only one hot water to meet demand, and to increase thermal efficiency An object of the present invention is to provide a hot water boiler capable of maintaining a uniform lifespan while rising.

상기한 목적을 달성하기 위하여, 본 발명은,In order to achieve the above object, the present invention,

열매체를 채운 보일러 통체와;
상기 보일러 통체의 상부에 내장한 1개의 열교환기와;A boiler barrel filled with a heating medium;
One heat exchanger built in the upper part of the boiler body;

상기 열교환기의 헤더를 십자(+)형으로 분할하여 하부와 상부에 각각 형성한 제1ㆍ제2급수실 및 제1ㆍ제2온수배출실과;first and second water supply chambers and first and second hot water discharge chambers respectively formed in the lower part and upper part by dividing the header of the heat exchanger into a cross (+) shape;

상기 제1ㆍ제2급수실과 제1ㆍ제2온수배출실에 각각 연결하고, 입구 및 출구 측에 제어밸브를 부설한 제1ㆍ제2급수관 및 제1ㆍ제2온수배출관과;first and second water supply pipes and first and second hot water discharge pipes respectively connected to the first and second water supply chambers and the first and second hot water discharge chambers, and having control valves installed at inlet and outlet sides;

상기 제1ㆍ제2급수관과 제1ㆍ제2온수배출관 사이에 각각 연결한 제어밸브 부설 급수용 바이패스도관 및 온수배출용 바이패스도관;을 포함한 것이다.It includes; a bypass conduit for supplying water and a bypass conduit for discharging hot water respectively connected between the first and second water supply pipes and the first and second hot water discharge pipes.

이상과 같이 본 발명은 보일러 통체의 상부에 1개의 열교환기만을 내장함으로써 부피를 작게 형성할 수 있기 때문에 제조비용과 설치면적을 작게 차지할 수 있어 경제적이다.As described above, the present invention is economical because the volume can be formed small by embedding only one heat exchanger in the upper part of the boiler cylinder, and thus the manufacturing cost and the installation area can be small.

또한 본 발명은 열교환기는 1개만 내장하여 온수 생성시 항상 가동함으로써 계절적 요인 등에 따라 종래 2개의 열교환기 중 1개의 열효교환기만을 가동할 때 열효율이 저하되던 문제점이 시정되어 열효율을 상승시킬 수 있는 것이다.In addition, in the present invention, since only one heat exchanger is built-in and is always operated when hot water is generated, the problem that the thermal efficiency is lowered when only one of the conventional two heat exchangers is operated depending on seasonal factors, etc., is corrected, and the thermal efficiency can be increased. .

그리고 본 발명은 1개의 열교환기에서 난방용 온수와 급탕용 온수를 동시에 생성함으로써 열교환기의 구조를 단순화할 수 있고, 또한 계절적 요인 또는 소요되는 수요량(사용량)이 난방용 온수와 급탕용 온수를 동시에 즉 난방용 가열회로와 급탕용 가열회로의 2개의 가열회로를 동시에 형성할 때의 온수의 수요량 보다 많아질 때 난방용 가열회로와 급탕용 가열회로 중 어느 하나의 가열회로만을 형성함으로써 그 특정용도의 온수의 수요량을 원활하게 공급할 수 있어 사용자의 욕구를 충족시킬 수 있는 것이다.And the present invention can simplify the structure of the heat exchanger by generating hot water for heating and hot water for hot water supply at the same time in one heat exchanger, and also seasonal factors or the required quantity (usage) of hot water for heating and hot water for hot water supply are simultaneously generated for heating. When the demand for hot water is higher than the demand for hot water when two heating circuits, a heating circuit and a heating circuit for hot water supply, are formed at the same time, the demand for hot water for a specific purpose is reduced by forming only one heating circuit among the heating circuit for heating and the heating circuit for hot water supply. It can be supplied smoothly to satisfy the needs of users.

그뿐만 아니라, 본 발명은 계절적 요인 또는 수요량의 중단 등의 원인으로 난방용 온수 또는 급탕용 온수 중 어느 하나의 생성을 중단하여도 열교환기는 항상 사용하기 때문에 종래와 같이 열교환기의 피로강도 차이에 의한 수명 차이 문제점이 발생하지 않고, 급수가 열교환기에서 가열될 때 모든 열교환관을 흐르면서 균일하게 가열되므로 열흡수율이 증대되어 열효율이 상승되는 것이다.In addition, according to the present invention, since the heat exchanger is always used even if the generation of either hot water for heating or hot water for hot water supply is stopped due to seasonal factors or interruption of demand, the lifespan due to the difference in fatigue strength of the heat exchanger as in the prior art There is no difference problem, and when the feed water is heated in the heat exchanger, it is heated uniformly while flowing through all the heat exchange tubes, so that the heat absorption rate is increased and the thermal efficiency is increased.
