태양열을 이용한 개방식 팽창탱크를 적용한 강제순환펌프식 급탕장치 {A DEVICE FOR FORCED CIRCULATION PUMP TYPE HOT WATER SUPPLY TO WHICH OPEN TYPE EXPANSION TANK IS APPLIED USING SOLAR ENERGY}Forced circulating pump type hot water supply device applying open expansion tank using solar heat {A DEVICE FOR FORCED CIRCULATION PUMP TYPE HOT WATER SUPPLY TO WHICH OPEN TYPE EXPANSION TANK IS APPLIED USING SOLAR ENERGY}
본 발명은 태양열을 이용한 개방식 팽창탱크를 적용한 강제순환펌프식 급탕장치에 대한 것으로서, 더 상세하게는 펌프를 사용하여 액상의 열매체를 강제순환시키고, 강제순환되는 열매체를 개방식 팽창탱크를 사용하므로써 내포된 공기를 자동제거하며, 보조가열수단의 위치를 축열탱크의 상단부에 설치하여 태양열에 의한 축열효과가 미비할 때 즉시 가열 공급으로 보조에너지를 아낄 수 있도록 하는데 특징이 있는 것이다.The present invention relates to a forced circulation pump type hot water supply device applying an open expansion tank using solar heat, and more specifically, forced heating of a liquid medium by using a pump, and the forced fluid is contained by using an open expansion tank. It automatically removes air and installs the location of auxiliary heating means at the upper end of the heat storage tank so that it can save auxiliary energy by heating supply immediately when the heat storage effect by solar heat is insufficient.
일반적으로 태양열을 이용한 온수가열 시스템은 그 설치장소와 설치방식에 따라 여러 가지의 형태로 나뉠 수 있으나, 가장 대표적인 것으로는 그 표면이 검은 동판 또는 구리파이프로 이루어지는 집열기를 건물 지붕과 같은 장소에 설치하고, 상기 집열기의 내부에 열매체를 통과시키되, 그 열매체는 축열탱크의 내부에 마련한 열교환기로 순환시키므로써 축열탱크 내부의 물을 가열해 둘 수 있도록 하는 것이다.In general, the hot water heating system using solar heat can be divided into various types according to the installation location and installation method. The most representative one is to install a collector of black copper plate or copper pipe on the same place as the building roof. The heat medium is passed through the heat collector, and the heat medium is circulated by a heat exchanger provided in the heat storage tank to heat the water in the heat storage tank.
이때, 상기한 축열탱크에는 야간시, 우천시 또는 흐린 날씨로 태양열이 미흡할 때, 보조가열장치로써 대부분 전기히터를 내장하고 있다.At this time, the heat storage tank has a built-in electric heater as an auxiliary heating device when the solar heat is insufficient at night, rainy weather or cloudy weather.
그리고 상기한 액상의 열매체는 물과 같은 잠열축열재를 이용할 수도 있고, 이 물에 동결방지용 에틸렌 그리콜과 같은 부동액을 50:50의 비율로 섞어 사용할 수도 있다.In addition, the liquid heat medium may be a latent heat storage material such as water, or an antifreeze such as ethylene glycol for freezing may be mixed in a ratio of 50:50.
그러나 상기와 같은 종래의 태양열을 이용한 급탕시스템은 정전이나 열매체의 누설 또는 전기제어장치의 고장 등의 사유가 발생하였을 때, 열매체가 순환하는 배관 내부에 에어가 발생하게 되며, 이와 같이 발생된 에어는 대부분 지붕에 설치된 집열기의 상부측 배관 내부에서 정체되기 때문에 열매체의 원활한 이동을 방해하는 문제가 있다.However, in the conventional hot water supply system using solar heat, when a reason such as a power failure, leakage of a heat medium, or failure of an electric control device occurs, air is generated inside a pipe where the heat medium is circulated. Most of them are stagnant in the upper side pipe of the collector installed on the roof, there is a problem that prevents the smooth movement of the heat medium.
따라서 상기와 같은 문제 발생시 작업자가 일일이 지붕으로 올라가 집열기 일측에 마련해 둔 에어밸브를 열어 주어야 하는 불편이 있으며, 이와 같은 에어 배출작업을 신속히 수행하지 못할 때는 배관 내부를 이동하는 열매체의 수축과 팽창이 반복되면서 집열기는 물론 이들과 연결된 배관이 파열되는 문제를 일으키기도 한다.Therefore, when the above problem occurs, the worker has to go up to the roof one by one to open the air valve provided on one side of the collector, and when the air discharge operation cannot be performed quickly, the contraction and expansion of the heating medium moving inside the pipe are repeated. As a result, the collector and the pipes connected to them are also ruptured.
또 한, 열매체에 의하여 흡수된 태양열을 1대의 축열탱크에 저장시키도록 하였기 때문에 축열탱크에 저장된 온수를 저온과 고온으로 분리할 수 없게 되며, 이는 집열기에서 흡수된 태양열을 축열탱크의 내부에 일시적으로 저장시키는 단순한 열에너지 이송싸이클에 불과하여 태양열에 따른 난방과 온수의 가열효율이 매우 저하되는 단점이 있다.In addition, since the solar heat absorbed by the heat medium is stored in one heat storage tank, hot water stored in the heat storage tank cannot be separated at a low temperature and a high temperature. This means that the solar heat absorbed by the heat collector is temporarily stored inside the heat storage tank. There is a disadvantage that the heating efficiency of the heating and hot water due to solar heat is very low because it is only a simple heat energy transfer cycle to store.
특히, 야간이나 흐린 날씨 또는 우천시에는 집열기로 태양열을 직접 흡수할 수 없기 때문에 집열기에 흡수되는 태양열 만으로는 난방이나 금탕용 온수를 충분히 가열하지 못한다.In particular, since at night or cloudy weather or rainy weather it is not possible to directly absorb the solar heat with the collector, the solar heat absorbed by the collector alone does not sufficiently heat the heating or geumtang hot water.
그러므로 이때는 보조가열수단을 사용하여 축열탱크에 저장된 온수를 가열하게 되는데, 종래의 보조가열수단은 축열탱크의 아랫부분에 위치하도록 설치한 예가 대부분이며, 이러한 구조는 보조가열수단이 축열탱크 전체를 가열하는 결과를 가져오기 때문에 에너지의 낭비가 클 뿐만 아니라 그 상태에서 다시 태양을을 받을 수 있는 상황(다음날 아침 날이 밝아 졌다든지, 흐린날이 맑은 날로 개었다든지 하는 상황)이 되었더라도 이미 보조가열수단으로 전체의 물을 가열해 버렸기 때문에 태양열에 의한 축열을 전혀 할 수 없게 되는 폐단이 있다.Therefore, at this time, the hot water stored in the heat storage tank is heated by using the auxiliary heating means. The conventional auxiliary heating means is installed in the lower part of the heat storage tank in most cases, and such a structure is that the auxiliary heating means heats the entire heat storage tank. This is not only a waste of energy, but also a situation where you can receive the sun again (a brightened morning or a cloudy day). As a result, the entire water has been heated, so there is a closed end where solar heat can not be stored at all.
따라서 본 발명은 상기와 같은 종래의 문제점을 개선하기 위해 안출한 것으로, 발명의 주된 목적은 열매체용 펌프와 개방식 팽창탱크를 사용하므로써 액상의 열매체가 유동하는 배관의 내부에 에어가 발생하여 정체되는 현상을 방지할 수 있도록 하고, 이로써 열매체액을 원활하게 유동시켜 열매체액에 흡수된 태양열을 보다 효율적으로 회수함과 동시에 배관내의 에어제거를 위한 번거로운 작업과 에어의 열팽창에 따른 배관의 파손을 방지하여 전체 시스템의 반영구적인 사용이 가능하도록 하는데 있다.Therefore, the present invention has been made in order to improve the conventional problems as described above, the main object of the invention is the phenomenon that stagnant by the air generated inside the pipe in which the liquid heat medium flows by using a heat medium pump and an open expansion tank This enables the heat medium fluid to flow smoothly, thereby recovering the solar heat absorbed by the heat medium fluid more efficiently, and preventing troublesome work for removing air in the pipe and damage to the pipe due to thermal expansion of the air. It is to enable semi-permanent use of the system.
또 다른 한편으로는 보조가열수단을 축열탱크의 상단부에 설치하므로써 우천시나 다량온수 사용시 보조보일러 작동에 요구되는 온도의 70%∼80%까지 태양열로 미리 가열시키고 그 상태에서 10%∼30%에 해당하는 소량의 에너지만을 보조 열원으로 보충하므로써 보조에너지를 아낄 수 있도록 하는데 목적이 있다.On the other hand, by installing the auxiliary heating means on the upper part of the heat storage tank, it is preheated by solar heat up to 70% ~ 80% of the temperature required for the auxiliary boiler operation in rainy weather or when using a large amount of hot water. It aims to save auxiliary energy by supplementing only a small amount of energy with auxiliary heat source.
또 한, 축열탱크의 내부하단에 장착한 열교환 코일로부터 열을 흡수한 온수가 대류작용에 의해 온수 배출파이프가 연결된 상측으로 이동하고, 축열탱크의 하부는 온도 밀도차로 인해 저온 냉수가 저장되게 함으로써 태양열 흡수 효율을 높일수 있도록 하는데 있다.In addition, the hot water absorbing heat from the heat exchange coil mounted on the inner bottom of the heat storage tank is moved to the upper side where the hot water discharge pipe is connected by the convection action, and the lower part of the heat storage tank is stored in low temperature cold water due to the temperature density difference. It is to improve the absorption efficiency.
뿐만 아니라 집열기 일측에 마련한 온도센서와 축열탱크 하단에 마련한 온도센서의 비교 감지로 지속적인 축열작용이 가능하도록 하는데 목적이 있는 것이다.In addition, the purpose is to enable a continuous heat storage action by comparing the detection of the temperature sensor provided on one side of the collector and the temperature sensor provided on the bottom of the heat storage tank.

이때 본 발명에서는 상기한 열매체 가동수단(20)에는 열교환기(22)와 펌프(24)의 사이에 열매체 팽창탱크(23)를 마련하여, 상기 열교환기(22)의 끝단이 그 속의 열매체 속에 잠기도록 연결하고, 상기한 보조가열수단(30)은 상기한 축열탱크(10)의 내부에서 열교환기(22) 보다 높은 위치이면서 온수 배출파이프(11)에 근접된 위치에 설치하며, 상기한 집열기(21)의 상단과 상기한 열교환기(22)의 하단에 각각 온도센서(27)(28)를 부착하고, 이들 온도차이에 따라 펌프(24)의 구동을 지시할 수 있는 콘트롤러(40)를 구비하는 것이 중요한 구성이다.At this time, in the present invention, the heat medium moving means 20 is provided with a heat medium expansion tank 23 between the heat exchanger 22 and the pump 24, so that the end of the heat exchanger 22 is submerged in the heat medium therein.

상기와 같이 구성된 본 발명은 날씨가 맑아 태양열을 받을 수 있는 시간대와 날씨가 흐리거나 우천시 또는 밤시간대의 가동이 다르다.The present invention configured as described above is different from the operation of the time zone that can receive solar heat due to the clear weather or cloudy weather or rainy night time.
태양열을 받을 수 있을 때에는 태양열이 집열기(21)에 제공되므로 집열기 속의 열매체를 가열하게 되고, 이와 같이 가열된 열매체의 온도를 온도센서온도센서(27)가 감지하여 콘트롤러(40)로 제공하고, 콘트롤러(40)에서는 열교환기(22)의 하단에 마련된 또 다른 온도센서(28)가 감지한 온도값과 비교하여 집열기(21) 쪽의 온도가 높을 때에 한하여 펌프(24)를 구동시킨다.When solar heat is received, the solar heat is provided to the collector 21 to heat the heat medium in the heat collector, and the temperature sensor temperature sensor 27 senses the temperature of the heated heat medium in this manner and provides the controller 40 to the controller 40. At 40, the pump 24 is driven only when the temperature at the collector 21 side is high compared to the temperature value detected by another temperature sensor 28 provided at the lower end of the heat exchanger 22.
펌프(24)가 구동되면 열매체가 집열기(21)로부터 축열탱크(10) 내부의 열교환기(22) 속으로 흐르게 되고, 열교환기(22)에서는 다음의 열매체용 팽창탱크(23)로 보내진다.When the pump 24 is driven, the heat medium flows from the collector 21 into the heat exchanger 22 inside the heat storage tank 10, and the heat exchanger 22 is sent to the next expansion tank 23 for the heat medium.
상기 팽창탱크(23) 속에서는 열매체의 내부에 포함되어 있던 공기가 상측으로 모아지고, 모아진 다음에는 체크밸브를 통해 밖으로 배출된다.In the expansion tank 23, the air contained in the inside of the heat medium is collected upward, and after being collected, it is discharged out through the check valve.
따라서 기포가 제거된 열매체는 펌프(24)의 구동에 따라 다시 집열기(21)로 보내지며, 집열기에서 다시 태양열을 축적하여 열교환기(22)로 순환하게 되는 것이다.Therefore, the heat medium from which bubbles are removed is sent to the collector 21 again according to the driving of the pump 24, and the solar medium accumulates solar heat again in the collector to circulate to the heat exchanger 22.
상기와 같은 작동되면, 집열기(21)로써 축적한 태양열이 축열탱크(10) 내부에서 열교환기(22)를 통해 물을 가열할 수 있게 되는 것이다.When the operation as described above, the solar heat accumulated by the collector 21 is able to heat the water through the heat exchanger 22 in the heat storage tank (10).
한편, 집열기(21) 상측의 온도센서(27)에서 감지한 온도값이 열교환기(22) 하단의 온도센서(28)에서 감지한 값보다 낮을 때는 펌프(24)가 정지하여 축열탱크(10) 내부의 물에 축적된 열이 가능한 손실되지 않게 한다.On the other hand, when the temperature value detected by the temperature sensor 27 above the heat collector 21 is lower than the value detected by the temperature sensor 28 at the bottom of the heat exchanger 22, the pump 24 stops to store the heat storage tank 10. Ensure that the heat accumulated in the water is not lost as much as possible.
그리고 이 축열탱크(10) 내부의 물이 충분히 가열되지 않은 상태에서 온수 배출파이프(11)를 통해 물을 사용하면 즉시 보조가열수단(30)을 구동시킨다.In addition, when water is used through the hot water discharge pipe 11 in a state in which the water in the heat storage tank 10 is not sufficiently heated, the auxiliary heating means 30 is immediately driven.
본 발명에서의 보조가열수단(30)은 축열탱크(10)의 상측에 구비되어 있기 때문에 그다지 고온으로 작동하지 않아도 충분히 더운물을 제공할 수 있게 되며, 또 축열탱크 하반부의 물까지 모두 가열하지 않기 때문에 전기에너지의 낭비를 줄일 수 있고, 이 후에 날씨가 좋아져서 집열기(21)가 태양열을 축적하게 되면 온도센서(27)(28)의 측정 값에 따른 콘트롤러(40)의 지시로 다시 정상작동하게 된다.Since the auxiliary heating means 30 in the present invention is provided on the upper side of the heat storage tank 10, it is possible to provide sufficiently hot water even when not operating at a high temperature, and also does not heat all the water in the bottom half of the heat storage tank. The waste of electrical energy can be reduced, and when the weather improves thereafter, when the collector 21 accumulates solar heat, the controller 40 according to the measured values of the temperature sensors 27 and 28 resumes normal operation. .
이 때는 축열탱크(10) 내부의 물 전체가 가열된 상태가 아니므로 앞서 설명한 바와 같이 축열탱크(10) 내부의 열교환기(22)에서 다시 물을 가열할 수 있게 된다.In this case, since the entire water inside the heat storage tank 10 is not heated, water can be heated again in the heat exchanger 22 inside the heat storage tank 10 as described above.
한편, 본 발명에서는 열교환기(22)의 직전에 하향진 U자관부(22a)가 구비되어 있기 때문에 열매체가 순환하지 않는다 하더라도 이미 가열된 열매체 일부가 역류하지 않아 안전하다.On the other hand, in the present invention, since the downward U-shaped tube portion 22a is provided immediately before the heat exchanger 22, even if the heat medium does not circulate, part of the heated heat medium does not flow backwards and is safe.
위에서 상세히 설명한 바와 같은 본 발명은 열매체용 펌프와 함께 개방식 팽창탱크를 사용하였기 때문에 액상의 열매체가 유동하는 배관의 내부에 에어가 발생하여 정체되는 현상을 방지할 수 있다.Since the present invention as described in detail above uses an open expansion tank together with a heat medium pump, it is possible to prevent a phenomenon in which air is generated in the inside of a pipe through which the liquid heat medium flows.
그리고 에어가 제거되므로 해서 열매체액을 원활하게 유동시킬 수 있기 때문에 열매체액에 흡수된 태양열을 보다 효율적으로 회수할 수 있게 된 것이며, 동시에 배관내의 에어제거를 위한 번거로운 작업과 에어의 열팽창에 따른 배관의 파손을 방지할 수 있게 된 것이고, 전체 시스템의 반영구적인 사용이 가능한 것이다.And since the air is removed, the heat medium liquid can flow smoothly, so that the solar heat absorbed by the heat medium liquid can be recovered more efficiently, and at the same time, the cumbersome work for removing the air in the pipe and the heat expansion of the pipe It is possible to prevent breakage and semi-permanent use of the whole system.
또 본 발명은 집열기 상단에 구비한 온도센서와, 축열탱크 내부의 열교환기 하단에 마련한 온도센서로써 수시로 온도차이를 감지하여 열매체를 순환시킬 필요가 있을 때에만 펌프를 작동시키기 때문에 축열효과가 클 뿐만 아니라 열 손실을 최소로 줄일 수 있는 장점이 있다.In addition, the present invention is a temperature sensor provided at the top of the heat collector and a temperature sensor provided at the bottom of the heat exchanger in the heat storage tank to detect the temperature difference from time to time to operate the pump only when it is necessary to circulate the heat medium, the heat storage effect is not only large. But it also has the advantage of reducing heat losses to a minimum.
뿐만 아니라 보조가열수단을 축열탱크의 상단부에 설치하였기 때문에 우천시나 다량온수 사용시 보조보일러 작동에 요구되는 온도의 70%∼80%까지 태양열로 미리 가열된 상태에서 10%∼30%에 해당하는 소량의 에너지만을 보조 열원으로 가열하도록 하였기 때문에 보조에너지를 많이 아낄 수 있는 장점이 있다.In addition, since the auxiliary heating means is installed at the upper end of the heat storage tank, a small amount corresponding to 10% to 30% in the state of being preheated by solar heat up to 70% to 80% of the temperature required to operate the auxiliary boiler in rainy weather or when a large amount of hot water is used. Since only the energy to heat the auxiliary heat source has the advantage of saving a lot of auxiliary energy.
그 외에 축열탱크의 내부하단에 장착한 열교환 코일로부터 열을 흡수한 온수가 대류작용에 의해 온수 배출파이프가 연결된 상측으로 이동하고, 축열탱크의 하부는 온도 밀도차로 인해 저온 냉수가 저장되게 함으로써 태양열 흡수 효율을 높일 수 있는 것이며, 이러한 장치를 가능한 물 사용처에 가깝도록 옥내에 구비하므로써 불필요한 열의 손실 없이 사용효과를 극대화 할 수 있게 된 것이다.In addition, hot water absorbing heat from the heat exchange coil mounted at the bottom of the heat storage tank moves to the upper side where the hot water discharge pipe is connected by the convection action, and the lower part of the heat storage tank is stored with low temperature cold water due to the temperature density difference. The efficiency can be increased, and by equipping such devices indoors as close to water as possible, the use effect can be maximized without unnecessary heat loss.
