본 발명은 열매체 보일러의 온수 공급장치에 관한 것으로서, 더욱 상세하게는 난방에 주로 사용되는 열매체로 온수를 직접 가열함과 동시에 배기가스열에 의 해서도 온수를 가열할 수 있도록 함으로써, 여름철 보일러를 사용하지 않더라도 별도의 전기 히터 없이 온수를 신속하게 공급할 수 있도록 한 열매체 보일러의 온수 공급장치에 관한 것이다.The present invention relates to a hot water supply device for a heat medium boiler, and more particularly, by heating the hot water directly with a heat medium mainly used for heating, and also by heating the hot water by the exhaust gas heat, do not use a summer boiler. The present invention relates to a hot water supply device of a thermal medium boiler capable of quickly supplying hot water without a separate electric heater.

일반적으로 열매체를 이용한 보일러는 열매체의 축열성과 높은 순간 전도성을 이용한 것으로써 열매체를 실내 바닥으로 순환시켜 난방 하는 시스템이다. 열매체 보일러는 열회수율을 높이기 위하여 배기가스가 열매체 탱크의 외벽을 따라 흐르면서 폐열이 회수되도록 하는 것이 보통이다.In general, a boiler using a heat medium uses a heat storage property and high instantaneous conductivity to heat the heat medium by circulating it to an indoor floor. Heat carrier boilers usually allow waste heat to be recovered as the exhaust gas flows along the outer wall of the heat carrier tank in order to increase the heat recovery rate.

실용등록 제359575호는 열매체 보일러의 열효율을 높이기 위한 기술이 개시돼 있다. 이는 연소열이 열매체 유조의 내벽 하부를 따라 상향된 뒤 외벽 상부를 따라 하향 되어 배기되도록 함으로써 폐열 회수를 적극적으로 하고 또한 배기관의 상부에는 온수를 공급하기 위한 수조를 설치하여 배기가스 열기로 온수가 가열되도록 하였다.Utility Registration No. 359575 discloses a technique for improving the thermal efficiency of a thermal medium boiler. This means that the heat of combustion is increased along the lower part of the inner wall of the heat medium tank and then exhausted downward along the upper part of the outer wall to actively recover the waste heat. It was.

그러나 상기 실용등록 제359575호는 연소된 배기가스 열이 열매체 유조의 외벽을 따라 흐르면서 폐열을 회수하는 효과는 있으나, 보일러를 항상 가동하지 않는 여름철에는 온수를 신속하게 제공할 수 없는 단점이 있었다.However, the Utility Registration No. 39575 has the effect of recovering the waste heat as the burned exhaust gas heat flows along the outer wall of the heat medium oil tank, but has a disadvantage in that hot water is not provided quickly in the summer when the boiler is not always operated.

온수를 공급하기 위한 수조는 배기 열로써 가열되나 여름철에는 보일러가 항상 가동되지 않으므로 수조의 물 온도가 낮아 온수를 신속하게 공급하지 못하는 단점이 있다. 결국 보일러를 가동하고 바로 온수가 공급되지 못하므로 별도의 전기히터를 수조에 내장시켜 물을 가열시켜야 되는 등의 보완이 필요하므로 전기료가 많이 발생되고 소비자의 부담으로 이어지는 등의 단점이 있었다.The water tank for supplying hot water is heated by exhaust heat, but since the boiler is not always operated in summer, the water temperature of the water tank is low, and thus hot water cannot be supplied quickly. Eventually, the hot water is not supplied immediately after starting the boiler, so a separate electric heater is required to be built in the water tank to supplement the water, which causes a lot of electric charges and leads to the burden on the consumer.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서 본 발명의 목적은 배기가스 열로 온수탱크의 물을 가열시키는 것은 물론 난방시 사용하는 열매체를 이용하여 온수탱크의 물을 직접 가열시킴으로써, 보일러를 항상 가동하지 않는 여름철에 온수를 신속하게 공급할 수 있으므로 온수 온도를 높이기 위하여 보일러를 필요이상 가동할 필요가 없으며 별도의 전기히터를 구비할 필요가 없으므로 시설비를 절약할 수 있는 열매체 보일러의 온수 공급장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to heat the water in the hot water tank by heating the water of the hot water tank as well as directly heating the water in the hot water tank using the heating medium used for heating, thereby always operating the boiler. It is possible to supply hot water quickly during the summer season, so it is not necessary to operate the boiler more than necessary to increase the temperature of the hot water, and it is not necessary to equip a separate electric heater, thus providing a hot water supply device of the thermal medium boiler that can save the facility cost. have.

As such, by heating again after the first heating using waste heat, hot water can be quickly heated without a separate electric heater, and the boiler does not need to be preheated more than necessary to save hot water and fuel. will be.

이러한 본 발명의 온수공급과정을 좀더 상세히 설명하면 다음과 같다.Referring to the hot water supply process of the present invention in more detail as follows.

버너(1)에 의해 연소실(2)에서 연료가 연소되면 이를 감싸고 있는 열매체(6)가 가열된다. 그리고 연소과정에서 발생되는 배기가스는 배기관(3)을 타고 배출되면서 잔열에 의하여 1차열교환기(11)를 가열시키며 온수탱크(10)의 물이 1차열교환기(11)되어 순환하면서 가열된다.When fuel is burned in the combustion chamber 2 by the burner 1, the heat medium 6 surrounding it is heated. The exhaust gas generated in the combustion process is discharged through the exhaust pipe 3 to heat the primary heat exchanger 11 by residual heat, and the water in the hot water tank 10 is heated while circulating through the primary heat exchanger 11. .

그리고 순환펌프(15)가 작동되면 가열된 열매체(6)가 2차열교환기(13)로 순환되면서 이를 통과하는 온수탱크(10)의 물을 다시 2차 가열시키게 된다.
이에 따라 온수탱크(10)의 물은 잔열에 의한 1차열교환기(11)에서 가열되고, 2차열교환기(13)를 통과하면서 좀더 적극적으로 가열되므로 온수의 가온효과를 증대하여 사용하기에 충분한 온도가 된다. 따라서 보일러를 가동하고 조금 있으면 바로 온수를 사용할 수 있으므로 온수 온도를 높이기 위한 보일러의 예열시간이 줄어들고 또한 별도의 전기히터를 사용할 필요가 없으므로 전기료와 연료를 절약할 수 있는 것이다.When the circulation pump 15 is operated, the heated heat medium 6 is circulated to the secondary heat exchanger 13, thereby again heating the water of the hot water tank 10 passing therethrough.
Accordingly, the water in the hot water tank 10 is heated in the primary heat exchanger 11 due to residual heat, and more actively heated while passing through the secondary heat exchanger 13, thereby increasing the warming effect of the hot water. Temperature. Therefore, since the hot water can be used immediately after the boiler is running, the preheating time of the boiler to increase the hot water temperature is reduced, and there is no need to use a separate electric heater, thereby saving electricity and fuel.

겨울철에는 보일러를 계속 가동하므로 온수탱크(10)의 물이 항상 가열된 상태인 반면에 여름철에는 보일러를 사용하지 않으므로 온수탱크(10)의 수온이 낮은 상태로 되는 것은 당연하다. 이러한 온수탱크(10)의 물이 1차열교환기(11)와 2차열교환기(13)를 거치면서 순간적으로 가열되므로 여름철에도 온수를 신속하게 제공할 수 있는 것이다. 그리고 열매체를 보충할 수 있는 열매체 보충탱크가 구비되므로 열매체의 열기를 충분히 이용할 수 있는 효과가 있다.Since the boiler continues to operate in winter, the water in the hot water tank 10 is always heated, while in the summer, the boiler is not used, so the water temperature of the hot water tank 10 is low. Since the water in the hot water tank 10 is instantaneously heated while passing through the primary heat exchanger 11 and the secondary heat exchanger 13, hot water can be quickly provided even in summer. And since the heat medium supplement tank is provided to replenish the heat medium has the effect that can fully utilize the heat of the heat medium.

이상에서와 같이 본 발명에 따르면 열매체를 2차열교환기로 순환시킴과 동시에 온수탱크의 물이 2차열교환기를 통과하면서 가열되도록 함으로써, 별도의 전기히터 없이도 온수를 신속하게 제공할 수 있다.As described above, according to the present invention, the heat medium is circulated to the secondary heat exchanger and at the same time the water of the hot water tank is heated while passing through the secondary heat exchanger, thereby providing hot water quickly without a separate electric heater.

본 발명은 실내로 순환되는 열매체를 이용하여 온수를 가열시키는 것이므로 별도의 전기히터 같은 열원이 필요 없어 시설비가 줄어들고 또한 전기료가 절감되며 온수를 가열시키기 위하여 보일러를 필요 이상 예열시키지 않아도 되므로 연료를 절감할 수 있는 등의 효과가 있다.The present invention is to heat the hot water by using the heat medium circulated to the room, so no separate heat source, such as an electric heater, the cost of the facility is reduced, and also saves on electricity costs, and does not need to preheat the boiler to heat the hot water to save fuel It can be effective.
