전기 온수기Electric water heater

제1도는 본 고안의 전체 상세도.1 is a detailed view of the present invention.

제2도는 본 고안의 축열체의 절개 사시도.2 is a cutaway perspective view of the heat storage body of the present invention.

제3도는 본 고안의 온수조 절개도.3 is a cutaway view of the hot water tank of the present invention.

본 고안은 잉여 심야 전력을 이용한 고온 축열식 전기 온수기의 개량에 관한 것이며, 특히 성에너지이 실현, 및 적은 설치면적에 적합하고 또한 소규모로 큰 축열효과를 거둘 수 있게 한 전기 온수기에 관한 것이다.The present invention relates to the improvement of a high temperature regenerative electric water heater using surplus late-night electric power, and more particularly, to an electric water heater in which sex energy is suitable for realization and a small installation area and a large heat storage effect can be achieved on a small scale.

심야전력을 이용하는 통상의 전기 온수기는, 축열조와 가열조를 분리 제작하여 이것을 수관으로 연결하고, 가열조내에 설치한 발열체에 전력을 공급하면 가열조의 수온이 상승함에 따라 축열조의 수온도 연결된 수관을 통해 같이 상승하는 구조로 되어 있다.A typical electric water heater using a late-night electric power separates and manufactures a heat storage tank and a heating tank, and connects them to a water pipe, and when electric power is supplied to a heating element installed in the heating tank, the water temperature of the heating tank rises through the water pipe connected to the water temperature of the heat storage tank. The structure rises together.

축열조의 수온이 85℃내외로 상승하면서 자동온도 조절기에 의해 전력공급은 차단된다. 물의 비등 온도는 100℃임으로 대량 축열을 요할 때는 축열조의 용적을 가급적 크게 해야 한다.As the temperature of the heat storage tank rises to around 85 ℃, the power supply is cut off by the thermostat. The boiling temperature of the water is 100 ℃, so when the large amount of heat storage is required, the volume of the heat storage tank should be as large as possible.

예로써, 50,000Kcal의 열을 85℃의 물로 축열하려면 1Kcal는 1ℓ의 물 1℃ 상승에 요한 열량으로 하려면, 50,000Kcal÷(85℃-20℃)=770ℓ가 소요된다.For example, to store 50,000 Kcal of heat with 85 ° C of water, 1Kcal requires 50,000Kcal ÷ (85 ° C-20 ° C) = 770L if the amount of heat required to raise 1 ° C of water is 1 ° C.

이것을 소용하려면 축열로 크기는 적어도 800ℓ용량은 가져야 한다,To avail this, the regenerative furnace must have a capacity of at least 800 l,

따라서, 종래에는 축열조의 제작비용과 이에 따르는 단열시공비 및 운반, 설치비용이 필요이상 과다하게 소요될 뿐 아니라, 설치장소도 넓어야 했다. 더욱이, 심야전력 공급시간 이후에는 부하(난방순환관 등)를 경유하여 돌아오는 저온의 순환수 때문에 축열조의 수온이 계속 하강하여 다음 심야전력 공급시간 이전까지 난방기능을 상실하다시피 함으로 그 전력과는 별도의 보조열원을 필요로 하는 등의 결함을 지니고 있었다. 이러한 연유로써 그 보급 실적이 저조했고, 그 결과 심야전력을 효과적으로 활용치 못해 막대한 지장을 주어왔다.Therefore, in the related art, not only the production cost of the heat storage tank and the heat insulation construction cost, transportation, and installation cost are excessively necessary, but also the installation place should be wide. Moreover, after the late night power supply time, the water temperature of the heat storage tank continues to drop due to the low temperature circulating water returning through the load (heating circulation pipe, etc.), and thus the heating function is lost until the next night power supply time. It had a defect such as requiring a separate auxiliary heat source. As a result, its performance has been low, and as a result, it has not been able to effectively utilize late-night power, which has caused enormous obstacles.

본 고안은 이러한 결점을 시정한 것으로 적은 용적에 큰 열량을 비축함으로써, 제작비, 설치경비, 운반비, 관리비 등의 제반비용 절감은 물론, 취급이 용이하여 그 신호도를 높임으로써 잉여 심야전력이 효과적인 활용을 도모할 수 있도록 하려는 것인바, 이를 첨부한 도면에 의거 상세히 설명하면 다음과 같다.The present invention corrects these shortcomings, and by storing large calories in a small volume, it is possible to reduce the overall costs such as manufacturing cost, installation cost, transportation cost, and maintenance cost, and to easily handle and increase the signal level so that the surplus late night power is effectively utilized. It is intended to be able to plan, which will be described in detail based on the accompanying drawings as follows.

축열체(1)는 산화마그네샤(MgO)를 주성분으로 하여 성형 소결한 것으로서, 그 특성은 비열이 0.27 내화도가 1800℃, 비중이 2.8인 특징을 갖고 있다.The heat storage body 1 is molded and sintered using MgO as a main component, and its characteristic is that the specific heat has a characteristic of 0.27 fire resistance of 1800 ° C and specific gravity of 2.8.

예로 축열체(1) 용적을 250×250×500(m/m)로, 발열체(2)의 소비전력을 10KW로, 심야전력 공급시간을 7시간으로 가정하여 700℃내외의 고온으로 가열할 경우에는 그 축열량은 860Kcal×7시간×10KW=60200Kcal인대 효율 85%로 보면 약 51200Kcal로 산출된다.For example, assuming that the heat storage body 1 has a volume of 250 × 250 × 500 (m / m), the power consumption of the heat generating element 2 is 10KW, and the night-time power supply time is 7 hours. The heat storage amount is 860 Kcal × 7 hours × 10 KW = 60 200 Kcal Ligament efficiency of 85% is calculated to be about 51200 Kcal.

이러한 고온을 효과적으로 간직하기 위해 대략 700℃정도에서 장시간 아무런 이상이 없게 하려면, 열전도율이 0.033Kcal/인 암면을 단열재(3)로 사용하는 것이 좋다.In order to keep such a high temperature effectively, if there is no abnormality for a long time at about 700 ° C, it is preferable to use rock wool having a thermal conductivity of 0.033 Kcal / as the heat insulating material 3.

고온 조절기(4) 시판중인 축열량 조절 및 온도 과승을 방지하는 전자식(電磁式)개폐기로서, 온도검출은 CA카플(4′)로 한다.High-temperature regulator 4 As a commercially available electronic switch which controls the amount of regenerative heat and prevents a temperature rise, the temperature detection is performed using a CA coupler 4 '.

심야전력(5′)을 누전차단기(5)와 고온 조절기(4)를 거쳐 공급받아 축열체(1) 속에 매설한 발열체(2)에 공급한다. 이때에 축열량은 고온조절기(4)의 설정에 따라 결정되며, 그 최고 온도는 적정수준(실험결과에 따르면 700℃내외가 좋다)이하로 한다.The midnight electric power 5 'is supplied through the earth leakage breaker 5 and the high temperature controller 4 and supplied to the heating element 2 embedded in the heat storage body 1. At this time, the heat storage amount is determined according to the setting of the high temperature controller 4, and the maximum temperature thereof is set at an appropriate level (according to the experimental results, about 700 ° C or less).

축열체(1)의 단열은 고온용 단열재(3)로 철저히 단열하여 열손실을 극도로 방지한다. 축열체(1)이 열은 방열구(6)를 통하여 열교환실(7)에 공급되며, 공지의 열교환기(8)는 그 열에 의해 온수조(9)의 물을 온수관(10)(10′)를 통하여 자연 대류 법칙에 따라 열교환된다.Insulation of the heat storage body (1) is thoroughly insulated with a high temperature insulator (3) to prevent heat loss extremely. The heat of the heat storage body 1 is supplied to the heat exchange chamber 7 through the heat dissipation opening 6, and the known heat exchanger 8 receives the water of the hot water tank 9 by the heat. Heat exchange in accordance with the law of natural convection.

온수조의 수온은 온수조절기(11)과 전자식 열개폐기(12)에 의해 조정되며, 그 기준은 85℃±5℃를 상한 온도로 한다.The water temperature of the hot water tank is adjusted by the hot water regulator 11 and the electronic heat switch 12, the reference is 85 ℃ ± 5 ℃ the upper limit temperature.

온수조(9)의 단열은 유리섬유 또는 폴리우레탄 폼(21) 등으로 하고, 온수조(9)의 수위는 수위조절기(13)에 의해 수관(14)를 통하여 항시 조절하며, 사고로 인해 물이 끌어넘치는 것 등은 일수관(15)를 통하여 외부에 배출 한다.Insulation of the hot water tank (9) is made of glass fiber or polyurethane foam (21), etc., and the water level of the hot water tank (9) is always adjusted through the water pipe (14) by the water level regulator (13), This overtaking is discharged to the outside through the water pipe 15.

부하로 공급되는 온수는 실내 조절기(16)와 순환펌프(17)에 의해 온수공급관(18) 및 환수관(19)을 통하여 강제로 이루어 진다.The hot water supplied to the load is forced through the hot water supply pipe 18 and the return pipe 19 by the indoor controller 16 and the circulation pump 17.

부하로 부터 회수되는 낮은 온도의 물이 온수조(9)로 유입되면 온수조(9)의 수온은 하강함으로 온수조절기1(1)와 전자식 열개폐기(12)는 작동하여 방열구(6)를 개방시켜서 축열제(1)의 열은 열교환기(7)로 유입하고 열교환기(8)는 온수조(9)의 수온을 설정온도까지 상승시키는 과정을 자동으로 반복하게 된다.When the low temperature water recovered from the load flows into the hot water tank (9), the water temperature of the hot water tank (9) is lowered so that the hot water regulator (1) and the electronic heat switch (12) operate to open the heat sink (6). The heat of the heat storage agent (1) is introduced into the heat exchanger (7) and the heat exchanger (8) automatically repeats the process of raising the water temperature of the hot water tank (9) to the set temperature.

온수조(9)의 구멍난 칸막이용 상부판(20)과 하부판(20′)은 부하에서 회수 되는 저온수로 인하여 발생하는 온도변화와 열교환기(8)동작때의 급격한 온도 변화를 완만하게 조절하는 역할을 한다.The perforated partition top plate 20 and the bottom plate 20 'of the hot water tank 9 smoothly adjust the temperature change caused by the cold water recovered from the load and the sudden temperature change during the operation of the heat exchanger 8. It plays a role.

수위 조절용 수원은 상수도(21)로 하며 실내온도 조절기(16) 및 순환펌프(17)의 전원은 일반전력(22)을 사용한다.The water level for adjusting the water source is a water supply 21, the power supply of the room temperature regulator 16 and the circulation pump 17 uses the general power (22).

각부의 구조물은 외함(24)을 씌워 보호한다.Each structure is covered by an enclosure (24).

위에서 상술한 바와 같이 적은 용적의 축열체에 대량의 열을 비축하고 열을 필요할 때 마다 물을 매체로 열교환하여 사용할 수 있으므로 온수조의 용량을 100ℓ이하로 소형화하여 하나의 기체속에 이들을 수용할 수 있기 때문에 제작비 절감을 물론 단열 효과도 향상되며 설치장소도 구애 받지 아니하며 운반 및 설치경비 등이 크게 절감된다. 때문에 대량 보급이 가능함으로 잉여 심야전력을 유효하게 활용할 수 있어 국가에너지 절약 정책에 큰 도움을 주는 등 이점이 있다.As described above, since a large amount of heat can be stored in a small volume of heat storage body and water can be used by heat exchange with a medium whenever heat is required, the capacity of the hot water tank can be reduced to 100 l or less so that they can be accommodated in one gas. In addition to the reduction in production costs, the insulation effect is also improved, regardless of the installation location, transportation and installation costs are greatly reduced. Therefore, it is possible to use a large amount of surplus late-night power effectively, which can greatly benefit the national energy saving policy.
