Description

태양광과 풍력의 복합 대체 에너지 발전을 연계한 열병합 발전 시스템{Multiple purpose integrated power cogeneration system using solar energy and wind power}Multiple purpose integrated power cogeneration system using solar energy and wind power}

본 발명은 태양광과 풍력의 복합 대체 에너지 발전을 연계한 열병합 발전 시스템에 관한 것으로서, 고효율의 에너지 절약형 시설로서 전기를 생성함과 동시에 발전 폐열을 공급하는 열병합 발전 시스템에 화석연료를 사용하지 않고 깨끗한 전기를 생산하는 태양광 발전기와 풍력 발전기를 연계하는 통합 에너지 발전 시스템을 구축함으로써,The present invention relates to a cogeneration system in which a combined alternative energy generation of photovoltaic and wind power is combined, and is a high-efficiency energy-saving facility that generates electricity and simultaneously supplies clean electricity without using fossil fuels in a cogeneration system that supplies waste heat. By building an integrated energy generation system that links solar generators and wind generators to produce

지역이나 건축물 전체에서 발생하는 다양한 에너지 수요(동일 수요처)를 도로 자체에서 생성한 전기만으로 동시에 충족할 수 있음은 물론 잉여전력을 얻게 되어, It is possible to meet various energy demands (the same demand) generated in the region or the entire building at the same time with electricity generated by the road itself, and also obtain surplus power.

풍차나 도로에 가설된 가로등이나 제설용 히터 등에 용도별로 유용한 에너지를 적절히 공급하므로서 에너지 이용 효율을 극대화시킬 수 있으며 또한 발전 폐열 뿐만 아니라 자연에너지를 병행하여 활용함으로써 광범위하게 연중 사계절 열공급(난방 및 급탕)과 전력공급 모두 가능하여 에너지 절약 및 경비절감에 기여할 수 있으며 대기오염 저감에 의한 환경보호와 축전과 축열기능으로 전기와 열수요의 계절 적 불균형에 적극 대응 할 수 있는 효과가 있다.      It can maximize energy use efficiency by appropriately supplying useful energy to windmills or streetlights or snow heaters installed on roads, and also use natural energy as well as waste heat of power generation to broadly supply four seasons throughout the year (heating and hot water). It can contribute to energy saving and cost reduction by being able to supply both power and electricity, and it can effectively respond to seasonal imbalances of electricity and heat demand through environmental protection and power storage and heat storage by reducing air pollution.

종래 다량의 전기에너지와 열에너지를 소비하는 아파트 등의 공동주택이나 업무용 빌딩, 소규모 공장 단지 등에서 전기에너지를 전력회사로부터 공급받고 있으나 발전에 따른 냉각 배열손실과 송전손실이 많고 난방 또는 냉방용 열에너지는 자체 보일러 또는 냉매 에어콘을 이용한 불규칙적이고 간헐적인 열에너지 공급으로 인하여 열효율이 현저하게 낮다.       Conventionally, electric energy is supplied from electric power companies in apartment houses, business buildings, and small factory complexes, such as apartments, which consume a large amount of electric energy and thermal energy, but there are many cooling arrangement losses and transmission losses due to power generation, and thermal energy for heating or cooling is itself Thermal efficiency is significantly lower due to irregular and intermittent thermal energy supply using boiler or refrigerant air conditioner.

상기한 문제점을 해결하여 열에너지와 전기에너지를 동시에 공급하는 열병합 발전(Cogeneration)은 원격지에서의 송전으로 송전 손실이 많은 일반 발전기에 비하여 대규모 발전소 건설의 부담이 경감되며 전기 등 에너지 수요지에서 전기를 직접 공급하는 분산형 전원으로 송전 손실이 적고 또한 에너지 수요에 즉각 대응이 가능하며 연료를 공급받아 발전기에서 전기를 생산하고 발전하는 과정에서 필연적으로 발생하는 폐열(배열)을 회수하여 유용하게 이용하는 고효율 에너지 기술로서종래의 발전방식보다 30∼40%의 전력 및 연료 등의 에너지 절감효과로 환경친화적이고 에너지 절약성이 좋은 장점이 있으나, 종래의 일반적인 열병합발전용 난방 및 급탕 배관만으로는 계절별로 난방열량의 과부족이 발생되어 에너지부하에 원활하게 대응할 수 없게 되고 대규모 집중형 시스템으로서 전력 및 열의 수송에 따른 비용의 과다와 전력 및 열손실로 인하여 경제성에 문제가 있었다. Cogeneration, which supplies heat energy and electric energy at the same time, solves the above problems and reduces the burden of large-scale power plant construction compared to general generators with high transmission loss due to power transmission from a remote location, and directly supplies electricity from energy demand sites such as electricity. It is a high-efficiency energy technology that uses a distributed power source that has low power transmission loss and can immediately respond to energy demand and recovers waste heat (array) that is inevitably generated during the generation and generation of electricity from a generator by receiving fuel. It has the advantages of being environmentally friendly and energy-saving with the energy saving effect of 30-40% of power and fuel than the conventional power generation method. Become unable to cope with energy load smoothly As a large-scale centralized system, there is a problem in economics due to excessive cost of power and heat transport and power and heat loss.

또한 고유가 시대가 다가오므로 인해 에너지 절약이 그 어느때 보다도 절실한 현재 선진 각국에서 활발히 기술개발이 진행되고 있으며 실용화 단계에 접어든 대체에너지로는 자연에서 생성할 수 있는 태양에너지와 풍력에너지를 주종으로 지열, 파력, 조력 등을 이용한 대체에너지 개발이 활발히 진행되고 있으나, 태양광을 이용한 태양에너지는 에너지를 응집시키는 기술력이 아직 부족하고, 구름이 많거나 비가 오게 되면 발전이 불가능하며, 설치비가 많이 들어 비경제적이고, 소규모 발전에만 적합한 문제점이 있으며, 풍력은 바람이 없으면 발전이 불가능하고, 설치 적지가 한정되어 있으며, 가동률이 낮아서 경제적이지 못한 단점이 있다.In addition, due to the approach of high oil prices, technology development is actively being carried out in advanced countries, where energy saving is more urgent than ever, and geothermal energy mainly includes solar energy and wind energy that can be generated in nature as alternative energy that has entered the stage of commercialization. Development of alternative energy using energy, wave, tidal, etc. is actively progressed, but solar energy using solar light is still lacking in technology for coagulating energy, and it is impossible to generate electricity when there are heavy clouds or rain. There is a problem that is only suitable for small-scale power generation, wind power is not possible without wind, power installation is limited, and the operation rate is low, which is not economical.

그 중에서 광 에너지와 열 에너지로 대별되는 태양 에너지 중에서 태양광 에너지는 광전지(솔라셀)을 이용하여 광 에너지를 전기 에너지로 변환하여 사용하며, 태양열 에너지는 집열판 등을 이용하여 열을 흡수하여 열매체에 전달하고 열매체에 흡수된 열을 이용하여 물의 온도를 높이는 방법으로 이용하고 있는데, 태양열 에너지는 에너지밀도가 낮고 일조시간이 짧고, 혹한이나 한파가 잦은 동절기에는 에너지 흡수량이 절대적으로 부족하여 집열효율이 떨어지므로 다른 보조 열원과 병합하여 사용하여야 하는 문제점이 있다.      Among them, solar energy, which is roughly classified into light energy and heat energy, is used by converting light energy into electrical energy using a photovoltaic cell (solar cell), and solar energy absorbs heat by using a heat collecting plate and so on It is used to increase the temperature of water by using the heat absorbed by the heat medium.The solar energy is low in energy density, short in sunshine time, and in winter when the cold or cold is frequent, the energy absorption is absolutely insufficient, resulting in poor heat collection efficiency. Therefore, there is a problem that must be used in combination with other auxiliary heat source.

또한 태양광 발전기의 광전지셀(PHOTOVOLTAIC CELL)에 태양광이 조사되면 광(光)기전력현상에 의해 전기가 발생되는 태양광 발전기도 구름이 끼거나 우기와 같이 태양광을 집광할 수 없을 때에는 전기를 생산할 수 없는 문제점이 있다.       In addition, when solar light is irradiated to a photovoltaic cell of a solar generator, a solar generator that generates electricity by photovoltaic phenomenon also generates electricity when it cannot collect sunlight such as clouds or rainy season. There is a problem that cannot be produced.

또한 도로에 관련된 시설로 야간에 빛을 밝혀서 시민의 활동을 자유롭게하는 가로등은 별도의 전력선 설치 등 전기 공급시설이 필요하고,In addition, the street-related facilities that turn on the lights at night to free citizens' activities require electricity supply facilities, such as installing a separate power line.

동절기에 일정 기온 이하에서 도로가 결빙되거나 강설로 눈이 쌓이게 되면 차량사고와 교통체증, 도로 결빙에 따른 파손 등 경제적 손실이 막대하게 발생되므로서 도로의 유지관리가 어려우며 계절에 관계없이 보다 쾌적하고 안전한 도로상태를 유지하게 하는 노면 결빙 방지 시설로서 별도의 히터를 구비하여야 하나 동절기에만 주로 사용하는 히터시스템의 불규칙한 피크수요에 대응하기 위하여 발전용량을 늘려야 하는 문제점이 있다. If the road freezes below a certain temperature in winter or snowfall due to snowfall, economic losses such as vehicle accidents, traffic jams, and road freezes are enormous, making road maintenance difficult and more pleasant and safe regardless of the season. As a road surface anti-freezing facility for maintaining road conditions, a separate heater should be provided, but there is a problem in that the generation capacity must be increased to meet the irregular peak demand of the heater system mainly used in winter.

따라서 본 발명자는 종래의 에너지 문제를 해결하는 대체 에너지를 연구한 바 버려지는 미활용 에너지를 회수 재활용하여 전기 및 열 수요처 전체를 발전소화 하는 방법으로 환경친화성, 에너지 절약성 및 에너지 공급의 유연성을 동시에 가지는 본 발명의 태양광과 풍력의 복합 대체 에너지 발전을 연계한 열병합 발전 시스템을 개발하게 된 것이다.     Accordingly, the present inventors have studied environmentally friendly energy, energy saving and energy supply flexibility by recovering and recycling unused energy discarded after researching alternative energy that solves the conventional energy problem. Eggplant is to develop a cogeneration system in conjunction with the combined alternative energy generation of solar and wind power of the present invention.

전술한 바와 같이 여러 가지 문제점을 가지고 있는 종래 기술의 열병합 발전시스템을 개선시키기 위하여 다양한 방법으로 미활용 에너지를 재활용하고 열효율을 개선시키는 방안이 제시되어 왔으나 미흡한 바,As described above, in order to improve the cogeneration system of the prior art having various problems, a method of recycling unutilized energy and improving thermal efficiency has been proposed in various ways.

열에너지를 공유시키는 네트워크 구성으로 난방이나 급탕, 조명, 제빙 등 에너지부하에 계절이나 시간에 구애받지 않고 유연하게 대처하여야 하는 기술 과제, It is a network configuration that shares heat energy, and it is necessary to flexibly respond to energy loads such as heating, hot water supply, lighting, and ice making regardless of season or time.

축열조의 에너지 저장 및 축열 성능을 향상시켜야 하는 기술 과제 등,Technical challenges to improve energy storage and heat storage performance

미활용에너지의 유효이용, 에너지 부하의 원활한 대응, 경제적 운전에 따른 종합 열효율향상 등 열역학적이나 경제성면에서 합리적이지 못한 풀어야 할 기술적 과제가 있다. There are technical problems to be solved that are not reasonable in terms of thermodynamics and economics such as effective utilization of unutilized energy, smooth response of energy loads, and improved overall thermal efficiency due to economic operation.

본 발명은 전술한 종래 기술의 문제점을 종합적으로 해결한 것으로서,The present invention as a comprehensive solution to the problems of the prior art described above,

고효율의 에너지 절약형 시설로서 전기를 생성함과 동시에 발전 폐열을 공급하는 열병합 발전 시스템에 화석연료를 사용하지 않고 깨끗한 전기를 생산하는 태양광 발전기와 풍력 발전기를 연계하는 통합 에너지 발전 시스템을 구축함으로써,As an energy-efficient facility with high efficiency, by building an integrated energy generation system that connects solar and wind generators that produce clean electricity without the use of fossil fuels in the cogeneration system that generates electricity and supplies waste heat.

지역이나 건축물 전체에서 발생하는 다양한 에너지 수요(동일 수요처)를 도로 자체에서 생성한 전기만으로 동시에 충족할 수 있음은 물론 잉여전력을 얻어, It is possible to satisfy various energy demands (the same demand) generated in the region or the entire building at the same time with electricity generated by the road itself, and also obtain surplus power.

열에너지를 공유시키는 배선 및 배관망 구성으로 전기 및 열 수용가는 물 론 풍차나 도로에 가설된 가로등이나 제설용 히터 등에 용도별로 유용한 에너지를 적절히 공급하므로서 에너지 이용 효율을 극대화시킬 수 있으며 또한 발전 폐열 뿐만 아니라 자연에너지를 병행하여 활용함으로써 광범위하게 연중 사계절 열공급(난방 및 급탕)과 전력공급 모두 가능한 태양광과 풍력의 복합 대체 에너지 발전을 연계한 열병합 발전 시스템을 제공하는 데 목적이 있다.  Wiring and pipe network structure that shares heat energy can maximize energy utilization efficiency by supplying useful energy for each purpose such as windmill, street lamp or snow heater installed on road as well as electricity and heat consumer. By utilizing energy in parallel, the goal is to provide a cogeneration system that combines the combined alternative energy generation of solar and wind power, which can be widely supplied with four seasons of heat supply (heating and hot water supply) and power throughout the year.

이와 같이 형성된 본 발명의 태양광과 풍력의 복합 대체 에너지 발전을 연계한 열병합 발전 시스템은,The cogeneration system in which the combined alternative energy generation of solar and wind power of the present invention formed as described above,

열병합 발전 시스템에 화석연료를 사용하지 않고 깨끗한 전기를 생산하는 태양광 발전기와 풍력 발전기를 연계하는 통합 에너지 발전 시스템을 구축하여 복수 개의 자연에너지를 이용한 소출력 발전시스템을 유기적으로 결합하고 열수요처 자체를 소출력 발전소화하여 에너지 공급을 상호 보완적으로 운영함으로써,Constructing an integrated energy generation system that connects a solar generator and a wind generator to produce clean electricity without using fossil fuel in the cogeneration system, organically combining a small power generation system using a plurality of natural energy, and outputting the heat demand itself. By becoming a power plant and operating energy supply complementarily,

지역이나 건축물 전체에서 발생하는 다양한 에너지 수요(동일 수요처)를 도로 자체에서 생성한 전기만으로 동시에 충족할 수 있음은 물론 잉여전력을 얻을 수 있어 효율적이고 경제적으로 에너지를 얻음은 물론 한가지 종류의 발전으로 전력을 생산 공급하는 것보다 안정된 에너지를 공할 수 있으며, It is possible not only to satisfy various energy demands (same demand source) generated in the region or the whole building with electricity generated by the road itself, but also to obtain surplus power efficiently and economically. It can provide more stable energy than producing and supplying

발전 폐열 뿐만 아니라 자연에너지를 병행하여 활용함으로써 광범위하게 연중 사계절 열공급(난방 및 급탕)과 전력공급 모두 가능하여 에너지 절약 및 경비절감에 기여할 수 있으며 대기오염 저감에 의한 환경보호와 축전과 축열기능으로 전 기와 열수요의 에너지 부하에 따라 수요처 특성에 맞춰 광범위하면서도 유연하게 대처할 수 있는 효과가 있다.By using not only waste heat of power generation but also natural energy at the same time, it can contribute to energy saving and cost reduction all year round by supplying heat supply (heating and hot water supply) and electric power all year round. According to the energy load of energy and heat demand, it is possible to cope with a wide range of flexibility according to the characteristics of the demand source.

따라서 한전에서의 전력 공급이 끊겨도 자체에서 생산된 전기를 전기수요처의 상용 전력 및 비상 전력으로 공급함은 물론 난방 수요처의 난방 관련 설비의 구동 전력으로 공급하여 계절별, 수요처별 부하에 따른 에너지 수요와 난방 관련 설비의 부하에 환경친화적이고 값싼 전기와 열에너지를 연중 24시간 안정적으로 공급할 수 있다.Therefore, even if the power supply is cut off, KEPCO not only supplies its own electricity as commercial power and emergency power for electricity demand, but also as driving power for heating-related facilities in the heating demand area. Environmentally friendly, cheap electricity and thermal energy can be supplied to the loads of related facilities 24 hours a year.

이하 본 발명의 바람직한 실시예를 첨부 도면에 의하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with the accompanying drawings.

도 1과 도 2는 본 발명의 전체적 구성을 도시한 개략적인 구성도로서, 1 and 2 is a schematic diagram showing the overall configuration of the present invention,

본 발명은 전술한 바와 같이 열에너지와 전기 에너지를 동시에 공급하는 열 병합 발전기(30)에 자연 에너지를 이용하는 태양광 태양열 복합 발전기(20)와 풍력 발전기(10)를 부가 설치하여 복합 에너지 열병합 발전 시스템을 구축한다.According to the present invention, the combined solar power generator 20 and the wind generator 10 using natural energy are additionally installed in the combined heat generator 30 to simultaneously supply thermal energy and electrical energy as described above. Build.

본 발명은 열병합 발전기(30)를 주전력원으로 하고 보조 전력원으로서 태양광 태양열 복합 발전기(20)와 풍력 발전기(10)에서 상호 보완적으로 생산된 전력을 모아서 하나의 전력으로 통합 및 조정하여 자체에서 생산된 전기를 해당 지역의 수용가(80)와 도로 가로등(70), 도로 히터(60) 등 전기 수요처에 송전함으로써 한전에서의 상용 전력이나 비상 전력 공급 없이도 환경친화적이고 값싼 전기를 연중 24시간 안정적으로 공급할 수 있게 한다. The present invention combines the cogeneration generator 30 as the main power source and as a secondary power source by combining the power produced by the solar solar power generator 20 and the wind generator 10 complementary and integrated into a single power By transmitting electricity produced in-house to customers in the area (80), street lamps (70), road heaters (60), etc., they can use environmentally friendly and cheap electricity 24 hours a year without commercial or emergency power supply. Ensure stable supply

즉, 365일 24시간 가동되는 열병합 발전기(30)를 중심으로 태양광의 조도가 일정레벨 이상일 경우에는 태양광으로 발전하고, 태양광의 조도가 일정레벨 이하일 경우에는 풍력으로 상호 보완적으로 발전하여 전력 부하에 유연하게 대처하되, 태양광 태양열 복합 발전기(20)와 풍력 발전기(10)는 미도시한 제어장치에 의하여 콘트롤되는 무인 자동화 운전을 실시한다. That is, when the illumination intensity of the solar light centers around the cogeneration generator 30 which is operated 24 hours a day, 365 days or more, the solar power is generated by the solar power. To flexibly cope with, the solar PV combined generator 20 and the wind generator 10 performs an unmanned automated operation controlled by a control device not shown.

상기한 풍력 발전기(10)는 풍차장치가 지상에 설치되며 내부에 공간부가 형성된 타워형 지주 선단에 풍력에 의해 회전 작동되는 날개차가 결합된 공지의 구성으로서 풍력 발전기(10)에 의하여 생성된 전기는 전선 케이블 배선망을 경유하여 축전기(40)에 연결되는 시스템 구성으로, 환경 조건에 따라 정격 풍속이상의 풍력 이 발생하면 자연 에너지인 풍력을 날개차의 회전운동으로 변환 풍력 발전기(10)를 구동시켜 전기를 생성하게 되는데 조명기구를 풍력 발전기(10)의 타워에 구비하게 되면 가로등이 별도로 필요 없으며 자체 생성 전기로 조명을 수행하면서 시각적인 효과도 부차적으로 구현할 수 있다. The wind generator 10 is a well-known configuration in which the windmill is installed on the ground and a vane that is rotated by wind power is coupled to a tower-shaped prop tip formed with a space therein, and the electricity generated by the wind generator 10 is wired. It is a system configuration that is connected to the capacitor 40 via a cable wiring network. When wind power above the rated wind speed is generated according to environmental conditions, the wind turbine converts natural wind into the rotational motion of a vane. If the lighting fixture is provided in the tower of the wind generator 10, the street lamp is not required separately, and visual effects may be additionally implemented while performing lighting with self-generated electricity.

태양광 태양열 복합 발전기(20)는 태양열을 집열하여 열을 공급하는 집열판(22)에 수광된 태양광이 조사되면 광(光)기전력현상에 의해 전기를 발생시키는 광전지(22)(PHOTOVOLTAIC CELL)이 복합적으로 구비되어 전기와 열을 동시에 공급하는 장치로서 전기는 풍력 발전기(10)에서 생성된 전기와 함께 축전기에 축전되어 열병합발전기(30)에서 생성하는 전기와 함께 일조량이나 풍량에 상관없이 연중 상호 보완적으로 전기를 공급하게 된다. The solar photovoltaic composite generator 20 includes a photovoltaic cell 22 (PHOTOVOLTAIC CELL) that generates electricity by photovoltaic phenomenon when the received solar light is irradiated on the heat collecting plate 22 that collects solar heat and supplies heat. It is a device provided to supply electricity and heat at the same time, the electricity is stored in the capacitor together with the electricity generated in the wind generator 10, complementary to the year-round regardless of the amount of sunshine or air with the electricity generated by the cogeneration generator 30 To supply electricity.

즉, 바람이 부는 쾌청한 날에는 풍력과 태양광을 모두 이용하여 전기를 생산하고, 흐린날에는 풍력으로 전기를 생산하며, 바람이 없는 괘청한 날에는 태양광에 의해 전기를 생산하게 되며, 잉여 전기를 축전하는 본 발명의 축전기(40)는 급속 충,방전이 가능하고 높은 충,방전 효율, 반영구적인 수명 고출력 등의 특성이 있는 슈퍼축전기를 사용하는 것이 바람직하다.      In other words, on a sunny day, wind is used to produce electricity using both wind and sunlight, on cloudy days, electricity is produced by wind power, and on windy days, wind is used to produce electricity by sunlight. As the capacitor 40 of the present invention for storing electricity, it is preferable to use a supercapacitor capable of rapid charging and discharging and having characteristics such as high charging and discharging efficiency and a semi-permanent lifetime high output.

열병합 발전기(30)는 전기를 공급합과 동시에 발전폐열을 이용 난방 및 급탕을 위해 축열하는 축열조(50)에 열을 축적하여 수용가(80)에 난방(급탕)열을 공급 하게 되는데 태양열과 더불어 열에너지를 공유시키는 배관망 구성으로 열매체의 가열 및 축열에 따른 에너지 효율을 극대화시키게 되는 것으로 축열조(50)는 태양열과 열교환되고 배관으로 공급되는 열매(물)로부터 열을 회수하여 축열하게 되며 이렇게 상호 보완적으로 부족한 열량릉 보충함으로써 축열조(저장탱크)의 크기가 축소되고 더불어 에너지 절약과 공해방지에 기여하게 된다. The cogeneration generator 30 supplies electricity and simultaneously heats the heat storage tank 50 to accumulate heat for heating and hot water by using waste heat to supply heating (hot water) heat to the consumer 80. In order to maximize energy efficiency due to heating and heat storage of the heat medium, the heat storage tank 50 is heat-exchanged with the solar heat and recovers heat from the fruit (water) supplied to the heat storage. By replenishing insufficient calories, the heat storage tank (storage tank) is reduced in size, contributing to energy saving and pollution prevention.

도시하지는 않았으나 상기 축열조(50)에는 열 공급이 원활하지 않을 경우에 온수의 온도를 기준 온도와 비교하여 열을 보충하여 주게끔 충전된 물 등의 열매체를 가열하는 히터를 추가적으로 설치할 수 있으며 열매체의 온도를 감지하는 온도센서(미도시함)와 마이크로 프로세서로 구동되는 제어장치도 동시에 구비하는 것이 바람직하다.      Although not shown, the heat storage tank 50 may be additionally provided with a heater for heating a heat medium such as water filled to compensate for heat by comparing the temperature of hot water with a reference temperature when the heat supply is not smooth. It is preferable to also have a temperature sensor (not shown) for detecting and a control device driven by a microprocessor at the same time.

또한 본 발명의 열공급 배관상의 필요한 요소 위치에는 압력 손실을 예방하는 부스터 펌프나 온수의 순환용 펌프, 용수나 가스의 유로를 개방 또는 폐쇄시켜 유량을 조절하거나 방향을 전환시키며 역류를 차단하는 다수의 밸브장치를 선택적이고 보충적으로 장착하여 열병합 발전 시스템을 안정적으로 가동할 수 있게 하는 것이 바람직하다.In addition, the required element position on the heat supply pipe of the present invention is a booster pump or a pump for circulation of hot water to prevent pressure loss, a plurality of valves to control the flow rate or change the direction by blocking the flow of water or gas by opening or closing the flow path of water or gas It is desirable to have optional and supplemental mounting of the device so that the cogeneration system can run stably.

결국 본 발명은 미활용에너지를 회수 이용하여 사계절 난방(급탕)과 냉방, 전력공급이 모두 가능한 복합 에너지원 열병합 발전 시스템으로서 전력 생산공정에서 발생하는 폐열(배열)과 풍력이나 태양열, 태양광 등 자연에너지를 복합적으로 활용하므로서 에너지 절약 및 경비절감에 기여할 수 있으며 대기오염 저감에 의한 환경보호와 축전과 축열기능으로 전기와 열수요의 계절적 불균형에 적극 대응 할 수 있어 계절이나 시간 등 환경 여건에 구애받지 않는 효과가 있다.      As a result, the present invention is a combined energy source cogeneration system capable of all four seasons heating (hot water supply), cooling, and power supply by recovering unused energy, and waste heat (array) generated in the power production process, and natural energy such as wind, solar heat, and solar light. It can contribute to energy saving and cost reduction by using it in combination, and can actively respond to seasonal imbalances of electricity and heat demand by environmental protection, electricity storage and heat storage function by reducing air pollution, so that it is not affected by environmental conditions such as season or time It works.
