본 발명은 열병합발전과 개별난방 통합시스템에 관한 것으로, 더욱 상세하게는 열병합발전 시스템과 개별난방 시스템을 동시에 실시하되, 열병합발전 과정에서 발생되는 폐열을 통해 급탕수의 온도를 높여주어 이를 직접 배출시키거나 개별보일러로 공급해줌으로써 개별보일러의 연료 소모량을 절감할 수 있도록 한 것이다.More particularly, the present invention relates to a cogeneration system and a cogeneration system, wherein the cogeneration system and the individual heating system are operated at the same time, and the temperature of the hot water is raised through the waste heat generated in the cogeneration process, Or by supplying them to individual boilers so that the fuel consumption of individual boilers can be reduced.

주지하다시피, 아파트와 같은 공동주택에는 큰 크기의 중온수보일러를 통해 물을 가열하여 이를 각 세대별로 공급해주는 중앙난방 시스템과, 각 세대별로 각각 개별보일러가 설치되어 이를 통해 각 세대별로 개별적인 난방을 하는 개별난방 시스템의 2가지 방식 중 어느 하나의 방식이 적용되어 난방 및 급탕기능을 수행하고 있다.As we all know, apartment houses and similar houses have a central heating system that supplies water to each household by heating water through a medium-sized water boiler, and individual boilers are installed for each household. The heating and the hot water supply function are performed by applying any one of the two methods.

이 중 중앙난방 시스템은 모든 세대별로 동일한 온도를 갖는 물을 공급해주게 되므로 관리가 용이한 이점은 있으나, 사람마다 취향이 다르고 자신이 원하는 시간에 난방을 할 수 없는 단점이 있어 개별난방 시스템을 더 선호하는 경향이 있다.Among them, the central heating system provides the water with the same temperature for every household, so it has the advantage of easy management, but it has the disadvantage that the people have different tastes and can not heat at the desired time. .

그런데, 최근 난방기 또는 냉방기의 보급이 많아지면서 동절기 또는 하절기에 전력사용량이 증가됨에 따라 전력요금 누진제로 인해 과도한 요금이 발생되고 있어 이를 감안하여 전기 및 열을 발생시킬 수 있는 열병합발전 시스템이 대두되고 있다.In recent years, as the amount of electric power used in the winter season or the summer season has increased due to the increase of the supply of the heater or the air conditioner, an excessive charge is generated due to the electric power rate progression system, and a cogeneration system capable of generating electricity and heat is emerging .

열병합발전 시스템은 열병합 발전기를 통해 전기와 함께 열을 발생시켜 이를 세대별로 공급해주는 방식으로서, 이와 같은 열병합 발전을 통해 발생되는 전기의 경우 전체 수요량의 70∼80% 정도이고, 열량의 경우 전체 수요량의 30% 정도이므로 전기의 경우 그 부족분을 일반전력으로 충당하며, 열량의 경우 중앙난방 시스템과 병용하여 충당하는 방식이 제안된 바 있으나, 개별난방 시스템의 경우 각 세대별로 개별보일러가 설치되어 있으므로 중앙에서 관리하는 열병합발전 시스템과 서로 접목하기 어려워 전혀 시도된바 없었다.The cogeneration system generates heat with electricity through cogeneration generators and supplies it to every household. The electricity generated through such cogeneration is about 70 ~ 80% of the total demand, 30%, so the electricity is covered by the general electric power. In the case of the heat, the method of using it together with the central heating system has been proposed. However, in case of the individual heating system, It has not been tried at all since it is difficult to connect with the cogeneration system that manages.

그러나, 개별난방 시스템의 경우도 마찬가지로 동절기 또는 하절기 과부하로 인해 전력수급에 차질을 빚게 되는 문제는 공통적으로 가지게 되며, 급탕만 필요하고 난방은 필요없는 하절기와 같은 계절에도 급탕을 구현하기 위해서는 개별보일러를 가동해야만 하므로 불필요한 연료가 소모되는 단점이 있어 열병합발전과 개별난방을 통합한 시스템의 개발이 요구되고 있는 실정이다.However, in the case of the individual heating system, too, the problem of causing power supply disruption due to overheating in the winter season or during the summer season is common, and in order to realize hot water supply in the same season as the summer season, There is a disadvantage that unnecessary fuel is consumed. Therefore, it is required to develop a system that integrates cogeneration and individual heating.

본 발명은 이러한 점에 착안하여 안출한 것으로, 열병합발전기를 중앙에 구비하고, 각 세대별로 개별보일러를 설치하여 각 세대별로 난방을 수행할 수 있도록 하되, 열병합발전기의 폐열을 회수하여 급탕탱크에 축적함으로써 급탕탱크에 담긴 급탕수를 예열하고, 급탕탱크와 연결된 급탕공급관은 각 세대별 개별보일러의 급탕용 급수측에 연결하면서 급탕공급관으로부터 분지된 분지관은 개별보일러로부터 인출된 급탕관에 연결하며, 급탕공급관, 분지관, 급탕관에는 각각 단속밸브를 구비함으로써 열병합발전기와 개별보일러를 같이 사용하면서 계절에 맞게 단속밸브를 개폐하여 급탕탱크에서 예열된 급탕수가 직접 수도밸브로 배출되게 하거나, 개별보일러로 유입되도록 함으로써 연료비를 절감함과 동시에 사용상 편의성을 도모할 수 있는 열병합발전과 개별난방 통합 시스템을 제공하고자 하는 것이다.The present invention has been made in view of this point, and it is intended to provide a cogeneration power generator at the center and to install individual boilers for each household so that heating can be performed for each household. The waste heat of the cogeneration power generator is recovered, The branch pipe branched from the hot water supply pipe is connected to the hot water supply pipe drawn from the individual boiler, and the hot water supply pipe connected to the hot water supply tank is connected to the hot water supply side of the individual boiler for each household, The hot water supply pipe, the branch pipe, and the hot water supply pipe are each equipped with the intermittent valve, so that the cogeneration unit and the individual boiler are used together and the hot water valve preheated in the hot water tank is discharged directly to the water valve, Which can reduce the fuel cost and facilitate the use of the fuel. It intended to provide a unified development and individual heating system.

이하, 본 발명을 제시되는 실시예와 첨부된 도면에 따라 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the attached drawings.

도 1은 본 발명에 따른 열병합발전과 개별난방 통합시스템의 개략 구성도이고, 도 2는 개별보일러가 이미 설치되어 있는 세대에 본 발명 적용시 배관 상태도이며, 도 3은 개별보일러를 새로 설치하는 세대에 본 발명 적용시 배관 상태도이다.FIG. 1 is a schematic configuration diagram of a cogeneration system and an individual heating and heating system according to the present invention, FIG. 2 is a piping state diagram when the present invention is applied to a household in which individual boilers are already installed, In which the present invention is applied.

도시된 바와 같이, 본 발명에 따른 열병합발전과 개별난방 통합시스템은, 가스를 공급받아 전기를 생산하는 열병합발전기(10)와, 내부에는 냉각수가 유동하면서 열병합발전기(10)의 폐열을 회수하는 폐열회수관(40)과, 하부 일측에 연결된 급수구(31)를 통해 급탕수가 공급되는 폐쇄된 형상의 급탕탱크(30)와, 급탕탱크(30)의 하부 측방에 연결되어 급탕탱크(30) 내부에 채워진 물을 순환시키면서 열교환기(20)를 통해 폐열회수관(40)으로부터 열을 전달받아 급탕탱크(30) 내부에 열을 축적해주는 급탕가열관(90)과, 급탕탱크(30)의 상단부에 연결되어 급수구(31)를 통해 급탕수가 급탕탱크(30) 내부로 공급되면 그 압력에 의해 급탕수를 배출하는 급탕공급관(32)과, 급탕공급관(32)이 그 급탕용 급수측에 연결되어 급탕공급관(32)을 통해 공급된 급탕수를 가열하여 급탕관(50)을 통해 수도밸브(60)로 배출하는 개별보일러(70)와, 급탕공급관(32)과 급탕관(50)의 사이에 연결되는 분지관(80)과, 급탕공급관(32)의 분지관과 개별보일러 사이위치, 급탕관(50)의 개별보일러와 분지관 사이위치, 분지관(80)의 임의의 위치에 각각 설치되어 급탕수의 공급방향을 단속하는 단속밸브(33)(51)(81)로 구성된 것이다.As shown in the drawings, the cogeneration system and the individual heating and cooling system according to the present invention include a cogeneration system 10 for generating electricity by receiving a gas, a cogeneration system 10 for recovering waste heat of the cogeneration system 10, A water supply tank 30 in the form of a closed shape to which hot water is supplied through a water supply port 31 connected to one side of a lower portion of the water tank 30; A hot water heating pipe 90 for circulating water filled in the hot water tank 30 and receiving heat from the waste heat recovering pipe 40 through the heat exchanger 20 to accumulate heat in the hot water tank 30, A hot water supply pipe 32 connected to the water supply port 31 for discharging the hot water by the pressure of the hot water supplied into the hot water tank 30 through the water supply port 31 and a hot water supply pipe 32 for connecting the hot water supply pipe 32 to the hot water supply side So that the hot water supplied through the hot water supply pipe 32 is heated, A branch pipe 80 connected between the hot water supply pipe 32 and the hot water supply pipe 50 and a branch pipe 80 connected to the hot water supply pipe 32, An intermittent valve 33 (51) installed at a position between the branch pipe and the individual boiler, a position between the individual boiler and the branch pipe of the hot water supply pipe (50) and an arbitrary position of the branch pipe (80) (81).

이때, 도시하지는 않았지만 급탕공급관(32)과 급탕관(50)은 개별보일러(70)의 내부에서 서로 연결되며, 열병합발전기(10)와 급탕탱크(30)는 아파트 단지의 보일러실과 같이 중앙관리가 용이한 위치에 설치하게 되고, 개별보일러(70)는 각 세대별로 설치함은 자명하다.Although not shown, the hot water supply pipe 32 and the hot water supply pipe 50 are connected to each other within the individual boiler 70. The cogeneration unit 10 and the hot water tank 30 are connected to each other by a central management It is easy to install the boiler 70, and it is obvious that the individual boiler 70 is installed for each household.

또한, 도 2와 같이 개별보일러(70)가 이미 설치되어 있는 경우 급탕공급관(32)을 기 설치되어 있는 급수관(71)에 연결하면서 급수관(71)의 급탕공급관 전위에는 단속밸브(72)를 설치하면 되며, 급수관(71)을 아예 폐쇄할 수도 있다.2, when the individual boiler 70 is already installed, an intermittent valve 72 is installed at the hot water supply pipe electric potential of the water supply pipe 71 while connecting the hot water supply pipe 32 to the installed water supply pipe 71 And the water supply pipe 71 may be closed at all.

도 3과 같이 개별보일러(70)를 새로 설치하는 경우 급수관 자체를 연결하지 않고, 급탕공급관(32)을 개별보일러(70)의 급탕용 급수측에 직접 연결하면 될 것이다.As shown in FIG. 3, when the individual boiler 70 is newly installed, the hot water supply pipe 32 may be directly connected to the hot water supply side of the individual boiler 70 without connecting the water supply pipe itself.

도면상의 미설명 부호 34는 수리 교체를 위해 급탕수의 공급을 차단할 수 있도록 급탕공급관(32)과 급탕탱크(30) 사이에 설치되는 예비 단속밸브를 나타낸다.Reference numeral 34 denotes a preliminary intermittent valve provided between the hot water supply pipe 32 and the hot water tank 30 so as to cut off the supply of the hot water for repair replacement.

이와 같이 구성된 본 발명에 따른 열병합발전과 개별난방 통합시스템은 다음과 같은 작용을 한다.The cogeneration system and the individual heating and cooling system according to the present invention configured as described above have the following functions.

먼저, 가스를 공급하여 열병합발전기(10)를 가동하게 되면 이로부터 전기가 발생되며, 이러한 전기는 한국전력으로부터 공급되는 일반전력과 같이 각 세대별로 인가해주어 전력수급이 원활히 이루어지도록 한다.First, electricity is generated when the cogeneration unit 10 is operated by supplying the gas. Such electricity is supplied to each household as in the case of the general power supplied from KEPCO, so that the power supply and supply can be smoothly performed.

열병합발전기(10)의 전력 생산과정에서는 필수적으로 폐열이 발생되며, 이러한 폐열에 의해 폐열회수관(40) 내부를 유동하는 냉각수가 가열되어 열교환기(20)측으로 이동하게 되고, 열교환기(20)에서 급탕가열관(90)과 열교환하여 온도가 내 려간 후 다시 열병합발전기(10)측으로 이동하여 다시 가열되는 과정을 반복하게 되며, 급탕가열관(90)은 급탕탱크(30) 내부의 물을 순환시키면서 폐열회수관(40)과 열교환하는 과정에서 열을 얻어 다시 급탕탱크(30)로 순환시키게 되므로 급탕탱크(30) 내부에 채워진 물은 지속적으로 열병합발전기(10)로부터 발생되는 폐열을 축적하게 된다.In the power generation process of the cogeneration power generator 10, waste heat is essentially generated, and the cooling water flowing in the waste heat recovery pipe 40 is heated by the waste heat to move to the heat exchanger 20 side, The hot water heating pipe 90 repeats the process of exchanging heat with the hot water heating pipe 90 and moving back to the cogeneration unit 10 after the temperature is lowered and the hot water heating pipe 90 repeats the circulation of water in the hot water tank 30 The heat is recovered and circulated to the hot water tank 30 in the course of heat exchange with the waste heat recovering pipe 40 so that the water filled in the hot water tank 30 continuously accumulates the waste heat generated from the cogeneration power generator 10 .

급탕탱크(30) 내부에서 지속적으로 예열된 급탕수는 급수구(31)를 통해 물이 공급됨과 동시에 그 압력에 의해 급탕탱크(30) 상단부에 연결된 급탕공급관(32)을 통해 이동하게 되는데, 하절기의 경우 난방을 하지 않고 급탕만 약간 필요하게 되므로 급탕관(50)과 급탕공급관(32)에 설치된 단속밸브(33)(51)를 잠그고, 분지관(80)에 설치된 단속밸브(81)만 열어주어 급탕수를 수도밸브(60)로 직접 배출시킬 수 있도록 하며, 동절기의 경우 난방을 실시함은 물론 급탕탱크(30)에 의해 예열되는 온도만으로는 충분히 뜨거운 물을 공급할 수 없으므로 급탕관(50)과 급탕공급관(32)에 설치된 단속밸브(33)(51)는 열어주고, 분지관(80)에 설치된 단속밸브(81)는 잠가주어 급탕수가 개별보일러(70)의 내부로 이동하도록 하는 것이다.The hot water that has been continuously preheated in the hot water tank 30 is supplied through the water supply port 31 and is moved through the hot water supply pipe 32 connected to the upper end of the hot water tank 30 by the pressure. The hot water supply pipe 33 and the hot water supply valve 33 provided in the hot water supply pipe 32 are closed and only the intermittent valve 81 provided in the branch pipe 80 is opened The hot water can be directly discharged to the water supply valve 60. In the winter season, the hot water can not be sufficiently supplied only at the temperature preheated by the hot water tank 30, The control valves 33 and 51 provided in the hot water supply pipe 32 are opened and the control valve 81 provided in the branch pipe 80 is locked to allow the hot water to move into the individual boiler 70.

이와 같이 개별보일러(70)로 급탕수가 유입되면 급탕수 자체가 이미 예열되어 있으므로 개별보일러(70)를 통해 원하는 온도만큼 급탕수의 온도를 올려줄 때 그 가열시간을 절약할 수 있으므로 결과적으로 연료비를 절감할 수 있는 것이다.Since the hot water is already preheated when the hot water flows into the individual boiler 70, the heating time can be saved when the temperature of the hot water is increased by the desired temperature through the individual boiler 70. As a result, It can save.

이때, 본 발명에 적용되는 단속밸브(33)(51)(81)는 일반적인 볼밸브를 사용하여 수동으로 제어할 수도 있으며, 또한 도면상에 도시하지는 않았지만 급탕공급관(32)의 일측에 온도센서를 설치하고, 단속밸브(33)(51)(81)를 전기적인 신호를 통해 제어가 가능한 솔레노이드 밸브로 구성하여 급탕탱크(30)에서 예열된 급탕수의 온도가 일정온도 이하이거나 이상이면 자동으로 솔레노이드 밸브를 단속하여 급탕수를 개별보일러(70)측으로 또는 수도밸브(60)측으로 이동시킬 수 있고, 이와 함께 개별보일러(70)를 자동으로 온/오프시킬 수도 있는 것이다.At this time, the control valves 33, 51, and 81 according to the present invention can be controlled manually using a general ball valve. Although not shown in the drawings, a temperature sensor is provided on one side of the hot water supply pipe 32 And a solenoid valve which can be controlled through an electric signal. When the temperature of the hot water preheated in the hot water tank 30 is lower than or equal to a predetermined temperature, the solenoid valve The valve can be interrupted to move the hot water to the individual boiler 70 side or the water valve 60 side, and the individual boiler 70 can be automatically turned on / off.

그리고, 설명하지는 않았지만 개별보일러를 통한 각 세대별 난방은 일반적인 것과 동일하게 이루어지게 된다.And, although it is not explained, the heating of each household through the individual boiler is performed in the same manner as usual.

이상에서 설명한 바와 같이, 본 발명은 열병합발전기와 개별보일러를 혼합 사용하되, 열병합발전기의 폐열에 의해 급탕수를 예열하여 계절에 따라 수도밸브로 직접 배출되게 하거나 개별보일러로 유입시키도록 한 것이므로 열병합발전 시스템과 개별난방 시스템의 장점을 접목할 수 있음은 물론 사용상 편의성을 도모할 수 있고, 개별보일러의 가스 소모량을 절감할 수 있으며, 급탕탱크에 의해 예열된 상태의 급탕수가 급탕공급관이나 분지관을 통해 유동하게 되므로 차가운 물에 비해 예열된 물의 용존산소량이 적어 관의 부식속도를 저하시킬 수 있고, 수도밸브를 통해 물의 배출시 초기부터 따뜻한 물이 공급될 수 있어 기존 개별보일러만으로 급탕을 공급할 때 초기 따뜻해질 때까지 차가운 물을 모두 버리는 것에 비해 물을 절약할 수 있는 효과도 있는 것이다.As described above, according to the present invention, since the cogeneration unit and the individual boiler are mixed, the hot water is preheated by the waste heat of the cogeneration unit, and the water is directly discharged to the water valve or introduced into the individual boiler according to the season. It is possible to combine the advantages of the system with the individual heating system, as well as to make it easier to use, to reduce the gas consumption of individual boilers, and to prevent the hot water from being preheated by the hot water tank to flow through the hot water supply pipe or branch pipe It is possible to lower the corrosion rate of the pipe because the amount of dissolved oxygen of the preheated water is lower than that of the cold water and the hot water can be supplied from the beginning when the water is discharged through the water valve. The effect of saving water compared to throwing out all the cold water It is.
