Description
본 발명은 열매체유를 이용한 축열식 전기 보일러에 관한 것으로 전기 히터를 이용하여 비열이 낮은 열매체유를 가열시켜 축열하고,(축열된 열매체유를) 열교환 파이프를 수조에 나선형으로 내설하여 축열된 열매체유를 순환 펌프로 이송시켜 물과 열교환시켜 물을 가열하여 난방, 급탕, 온풍기등으로 이용하면서, 안전성과 효율성을 높이는 축열식 전기보일러에 관한 것이다.The present invention relates to a heat storage type electric boiler using heat medium oil, and heats and heats heat medium oil having a low specific heat by using an electric heater, and heat accumulates heat storage pipes spirally in a water tank (heat storage heat medium oil). The present invention relates to a regenerative electric boiler that improves safety and efficiency while transferring water to a circulation pump and heat-exchanging with water to heat water and use it as a heating, hot water supply, and a hot air fan.
심야 전기의 활용방식으로 축열시켰다가 이를 열교환하여 사용하는 전기 보일러는 유휴 전력의 효율적 사용과 고유가의 대안으로 연구되면서 여러가지의 방법으로 실용화되고 있고,Electric boilers that use heat storage and heat exchange by using late-night electricity are being used in various ways as they are researched as an alternative to efficient use of idle power and high oil prices.
축열의 소재로는 액체(물 또는 열매체유), 고체(석재,금속)등이 주로 이용되고 있으며 이중 고체의 경우에는 산화와 부식이 빠르게 진행되고 축열과정에서 열손실이 많아 효율이 떨어져 널리 이용되지 못하고 주로 액체가 축열소재로 사용되고 있다.As heat storage materials, liquid (water or thermal oil) and solids (stone, metal) are mainly used, and in the case of solids, oxidation and corrosion progress rapidly and heat loss in the heat storage process is low, so they are not widely used. The liquid is mainly used as a heat storage material.
동 액체의 축열 소재 중에서 물의 경우에는 비열(단위 중량의 물체 온도를 1℃만큼 올리는데 소요하는 열량)이 높고 축열효율이 떨어져 가열상태에서 보관되었다가 사용되므로 탱크의 용량이 대형화되는 폐단이 있고,Among the heat storage materials of the liquid, in case of water, the specific heat (heat required to raise the unit temperature of object weight by 1 ℃) is high.
또 열매체유를 사용하는 경우에는 축열온도가 320 ℃에 이르는 고온이고 비열이 낮아 축열효율이 높아져 보일러의 본체가 작아지고 효율이 높은 잇점은 있으나 열매체유가 축열되면서 부피의 팽창과 축열된 열매체유를 이용하여 열교환이 이루어지는 과정에서 열의 손실이 많고 산화와 부식이 발생되면 폭발의 위험을 내재하고 있는 실정이다.In the case of using heat medium oil, the heat storage temperature is high temperature up to 320 ℃ and the specific heat is low, so the heat storage efficiency is high. Therefore, there is a lot of heat loss in the process of heat exchange, and oxidation and corrosion are inherent in the risk of explosion.
일예로 국내 등록 특허공보 특허등록번호 특0160589(등록일자 1998.08.19.) 열매체유를 이용한 축열식 전기 보일러의 경우,For example, in the case of a regenerative electric boiler using thermal oil, the patent registration number 0160589 (Registration date 1998.08.19.)
① 열매체유 주위로 난방 또는 급탕관을 나선형으로 감아서 구성되고 열교환을 위하여 순환 펌프에서 이송되는 용수는 유속으로 인하여 원하는 온도의 온수를 얻는데 소요시간이 길고,① It is composed by spirally winding heating or hot water supply pipe around heat medium oil, and the water transferred from circulation pump for heat exchange takes a long time to get hot water of desired temperature due to the flow rate.
② 온수 사용의 중단시 관에 내장된 용수가 열매체유에 의해 계속 가열되어 관내의 압력상승과 수증기의 발생으로 난방관의 경우 온수 순환에 장애가 발생되면서 폭발의 위험을 내재하고 있고,② When the use of hot water is interrupted, the water contained in the pipe is continuously heated by the heat medium oil, causing the explosion of hot water circulation in the heating pipe due to the increase in pressure and the generation of water vapor in the pipe.
③ 열매체유 탱크에는 열매체유가 축열되면서 320℃에 이르게 되면 열매체유는 20% 상당의 부피가 팽창되면서 발생되는 팽창 공기는 고온이므로 이를 흡수하는 주름탱크는 고온을 소화하여 주는 소재가 없어 현실적으로 불가능하고,③ When thermal oil reaches 320 ℃ as the thermal oil accumulates, the thermal oil generates 20% of its volume, and the expansion air generated is high temperature, so the corrugated tank absorbing it has no material that digests high temperature.
④ 열매체유 탱크 외곽에 나선형태로 위치되는 난방 또는 급탕관으로 이용되는 열교환 파이프는 축열 탱크의 온도보다는 낮아 외곽의 공간으로 열손실이 발생되기 때문에 열교환의 효율이 떨어지는 폐단이 있고④ Heat exchange pipes used as heating or hot water pipes located spirally outside the heat medium oil tank are less than the temperature of the heat storage tank, so heat loss is generated in the outer space, which leads to poor efficiency of heat exchange.
또 국내공개특허공보 공개번호 특1999-0045902 난방용 보일러 및 온풍기의 경우에는In addition, in the case of a domestic boiler publication No. 1999-0045902 heating boiler and hot air fan
① 열매체유조 외곽으로 수조가 구성되고 열매체유조 하부에는 연소실이 위치되므로 열매체유조의 산화 또는 부식이 발생될 경우 열매체유의 인화점이 260℃인점을 고려할 때 320℃까지 축열된 열매체유가 연소실로 유출될 경우 인화로 인한 폭발의 위험성이 내재되는 폐단이 있고,① The water tank is formed outside the thermal oil tank and the combustion chamber is located under the thermal oil tank. When oxidation or corrosion of the thermal oil tank occurs, the thermal oil, which has been stored up to 320 ° C when it is discharged to the combustion chamber, is considered to be ignited when the thermal oil flash point is 260 ℃. There is an inherent danger of explosion due to
② 열매체유조와 수조간에는 단열이나 열의 차단기능이 없어 열매체유조에서 축열되면서 발생되는 열이 수조로 전달되어 온수가 계속 가열되어 압력이 상승되고 이로 인한 폭발의 위험과 축열의 효과가 떨어져 안전성과 경제성이 떨어지는 폐단이 있다.② There is no insulation or heat blocking function between the thermal oil tank and the water tank, so the heat generated from the thermal oil tank is transferred to the water tank so that the hot water continues to be heated and the pressure rises, thereby reducing the risk of explosion and the effect of heat storage, thereby reducing safety and economy. There is a falling lung.
이에 본 발명은 열매체유를 이용하는 축열식 전기 보일러에서 열매체유가 물과의 열교환 과정에서 우려되는 폭발의 위험과 열매체유조와 수조간을 단열하여 열손실을 해소하며 축열의 보존 효율과 안전성을 높이는데 목적을 두고 있다.Therefore, the present invention aims to solve the risk of explosion during heat exchange process with water in heat storage type electric boiler using heat oil and to insulate between heat tank and water tank to solve heat loss and to improve storage efficiency and safety of heat storage. I put it.

본 발명에서 사용되는 열매체유의 성능과 성상은 아래표와 같다.The performance and properties of the heat medium oil used in the present invention are as follows.
※ 성능 (시중판매 s사 제품기준)※ Performance (Commercial product standard)
※ 성상※ Appearance
이와 같은 열매체유를 본 발명의 전기 보일러의 열매체유조(1)에 80%가 되도록 장입하고 수조(3)에는 물을 장입시켜 사용하게 된다.Such heat medium oil is charged to 80% in the heat medium oil tank 1 of the electric boiler of the present invention, and water is charged into the water tank 3 to be used.
즉 유휴전력이 발생되는 야간(22:00 ~ 08:00)에 전원으로 전기히터(2)를 동작하게 되면 전기히터(2)의 열원에 의해 열매체유조(1)의 열매체유가 가열되어 축열이 이루어지게 되는데 이는 비열이 낮아 축열속도가 빠르게 된다.That is, when the electric heater 2 is operated as a power source at night (22:00 ~ 08:00) when idle power is generated, the heat medium oil of the heat medium oil tank 1 is heated by the heat source of the electric heater 2 to generate heat storage. This is because the specific heat is low and the heat storage rate is high.
이와 같이 열매체유조(1)의 축열온도를 320℃에 설정하게 되면 열매체유가 320℃에 이르게 되면 전기히터(2)는 off되고 체적은 20%가 팽창되며 팽창으로 인하여 열매체유조(1)내의 공기는 열매체유조(1)의 팽창공기 흡·배기구(30)로 배출된다.When the heat storage temperature of the heat medium oil tank 1 is set at 320 ° C., when the heat medium oil reaches 320 ° C., the electric heater 2 is turned off and the volume is expanded by 20%. The air in the heat medium oil tank 1 is expanded due to expansion. The expansion air intake / exhaust port 30 of the heat medium oil tank 1 is discharged.
또 열매체유조(1)에 축열된 열매체유를 이용하여 수조(3)를 가열시켜 난방에 사용하고자 할때에는 열매체유조(1)에 연결된 열매체유의 순환펌프(13)를 가동시키게 되면 열매체유조(1)의 열매체유가 순환펌프(13)를 통하여 수조(3)의 나선형으로 설치된 열교환 파이프(14)에서 열이 발산되어 수조(3)의 물을 가열하게 된다.In addition, when heating the water tank (3) using the heat medium oil stored in the heat medium oil tank (1) to use for heating, when the circulation pump 13 of the heat medium oil connected to the heat medium oil tank (1) is operated, the heat medium oil tank (1) The heat medium oil of the heat is discharged from the heat exchange pipe 14 installed in a spiral of the water tank 3 through the circulation pump 13 to heat the water of the water tank 3.
이와 같이 가열된 수조(3)의 온수는 난방용 온수순환펌프(20)를 통한 온수출수관(23)을 통하여 난방관을 거쳐 다시 온수 회수관(24)으로 회수가 이루어지는 과정으로 온수난방이 이루어지고, 또 열매체유조(1)에 축열된 열매체유를 이용 급탕탱크의 물을 가열하거나 또는 온풍기에 연결하여 난방하는 경우에는 온수난방과 같은 방법으로 연결하거나 통상의 방법으로 연결하여 사용하게 된다.The hot water of the heated tank 3 is recovered in the hot water recovery pipe 24 through the hot water outlet pipe 23 through the hot water circulation pump 20 for heating. In addition, in the case of heating the water of the hot water supply tank by heating the heat medium oil heat-generated in the heat medium oil tank 1 or by connecting it to a hot air heater, it is connected by the same method as hot water heating or connected by a conventional method.
특히 본 발명은 열매체유조(1)와 수조(3) 사이에 단열재(10)를 충진하게 되므로서 열매체유조(1)의 열매체유가 전기히터(2)에 의해 가열되어 축열되면서 열매체유조(1)의 열이 수조(3)로 전달되거나 발산되지 않게 되므로 축열된 열매체유의 보존기간이 증대되고, 또 열매체유조(1)에서 인출되는 나선형의 열교환 파이프(14)가 수조(1)에 내장된 상태에서 열교환이 이루어지게 되므로 열교환시 열의 손실이 없어 효율이 증대되며, 또 산화와 부식이 발생되어 수조(3) 내의 열교환 파이프(14)가 누유 되더라도 수조(3)의 물의 온도가 급상승되지 아니하고 인화요인이 없어 폭발의 위험을 해소하게 된다.In particular, the present invention is filled with the heat insulating material 10 between the heat medium tank (1) and the water tank (3), while the heat medium oil of the heat medium tank (1) is heated and regenerated by the electric heater (2) of the heat medium tank (1) Since heat is not transferred or dissipated to the water tank 3, the storage period of the heat-retained heat medium oil is increased, and heat exchange is carried out in a state in which the spiral heat exchange pipe 14 drawn out of the heat medium oil tank 1 is embedded in the water tank 1. Therefore, there is no loss of heat during heat exchange, so the efficiency is increased, and even if the heat and heat exchange pipe 14 in the tank 3 leaks due to oxidation and corrosion, the temperature of the water in the tank 3 does not increase rapidly and there is no ignition factor. Eliminate the risk of explosion.
보다 구체적으로는 열매체유는 축열온도가 320℃에 이르는 반면 인화점이 260℃이므로 열매체유조(1)에 열교환 파이프(14)가 내장될 경우 열교환 파이프(14)가 산화와 부식이 발생되어 물이 누수되면 물이 급가열 팽창되어 열매체유조(1)가 폭발하게 되는 위험성이 있으나 본 발명은 열매체유조(1)에서 이송되는 열매체유는 나선형의 열교환 파이프(14)가 수조(3)에 내장된 상태에서 열교환이 이루어지게 되므로 수조(3)의 물량이 많아 급가열이 되지 않게 되므로 안전하게 되는 것이다.More specifically, since the heat storage temperature reaches 320 ° C and the flash point is 260 ° C, when the heat exchange pipe 14 is built in the heat medium tank 1, the heat exchange pipe 14 is oxidized and corroded, and water leaks. When the water is suddenly expanded and the thermal fluid tank (1) there is a risk of explosion, but the present invention is the thermal fluid oil conveyed from the thermal fluid tank (1) is a spiral heat exchange pipe 14 is built in the water tank (3) Since the heat exchange is made, the amount of water in the tank 3 is not safe because it is not suddenly heated.
또 본 발명은 난방 완료 후 또는 난방을 하지 않을 때에는 열매체유의 이송이 중단되므로 수조(3)가 급가열 되지 않아 온수의 순환에 장애 요인이 되는 압력상승등의 요인이 해소되므로 편리하게 사용할 수 있게 된다.In addition, the present invention can be conveniently used since the transfer of the heat medium oil is stopped after the completion of heating or when not heating, so that the water tank 3 is not rapidly heated and the factors such as the pressure rise that hinder the circulation of the hot water are eliminated. .
따라서 이상과 같은 본 발명은 열매체유를 이용하는 축열식 전기 보일러에서 열매체유와 물과의 열교환 과정에 우려되는 폭발의 위험과 열손실을 해소하여 안전하고 편리하게 사용할 수 있게 되는 매우 유용한 발명이다Therefore, the present invention as described above is a very useful invention that can be used safely and conveniently by eliminating the risk of explosion and heat loss in the heat exchange process between the heat medium oil and water in the heat storage type electric boiler using heat medium oil.
