본 발명은 흡수식 및 압축식 사이클을 이용한 열 병합발전시스템에 관한 것으로, 본 발명에서는 구동원에서 제공되는 전력 일부와 배기가스의 배열을 이용하여 흡수식 장치 및 압축식 장치를 각각 운전시킬 수 있도록 하고, 아울러 흡수식 사이클에서 증발기의 증발 잠열과 열교환 하는 저온 냉각수와, 압축식 사이클에서 제1 팽창밸브를 통과하면서 형성되는 일부 냉매 증기가 서로 열교환 될 수 있도록 구성함으로써, 자체적인 전력생산은 물론 압축식 사이클이 가지는 냉동용량이 더 증대되어 배열을 이용한 지역냉방을 효율적으로 수행할 수 있도록 한 것이다.The present invention relates to a combined heat and power generation system using absorption and compression cycles, and in the present invention, the absorption and compression apparatuses can be operated by using a part of the power provided from the driving source and the arrangement of the exhaust gases. The low-temperature cooling water that exchanges heat with the evaporative latent heat of the evaporator in the absorption cycle and some refrigerant vapors formed while passing through the first expansion valve in the compression cycle can be heat-exchanged with each other. The refrigeration capacity is further increased to efficiently perform district cooling using the array.

일반적으로, 열 병합발전시스템(Cogeneration System)은, 발전을 통한 전력과 열 공급을 동시에 생산하여 에너지 이용률을 높이는 발전 시스템이다.In general, a cogeneration system (Cogeneration System) is a power generation system that increases the energy utilization rate by simultaneously producing power and heat supply through power generation.

구체적으로, 엔진이나 터빈 등과 같은 구동원이 가동하면서 전력과, 배기가스의 배열을 동시에 생산하는 열 병합발전시스템을 이용하게 되면, 수용가에서 난방과 온수 사용을 위한 개별적인 보일러 가동 및 전력회사에서 제공되는 전력에 의존하지 않고 자체적으로 모두 수행할 수 있으므로 에너지 절약효과를 거둘 수 있는 장점이 있다.Specifically, when using a combined heat and power generation system that simultaneously generates power and exhaust gas arrays while a driving source such as an engine or a turbine is running, individual boiler operation for heating and hot water use in a consumer and power provided by a power company All of them can be done on their own, without relying on the energy savings.

위의 열 병합 발전시스템은, 구동원의 종류 혹은 타입에 따라 다소 차이가 있지만 예를 들어 구동원이 가스식 엔진일 경우, 약 120℃의 배기가스와 90℃의 냉각수로 배열이 발생하고, 터빈일 경우에는 약 300℃의 배기가스로 배열이 발생 되며, 이러한 배열을 이용하여 온수 및 난방을 수행하게 된다.The above combined heat generation system differs slightly depending on the type or type of driving source, but for example, when the driving source is a gas engine, the arrangement is generated by exhaust gas of about 120 ° C and cooling water of 90 ° C, and in the case of a turbine An arrangement is generated with exhaust gas of about 300 ° C., and hot water and heating are performed using this arrangement.

그런데, 상기 열 병합발전시스템에서 배기가스의 배열을 난방이 아닌 냉방의 열원으로 사용할 경우, 성적계수(coefficient of performance)가 낮은 중 온수 흡수식 냉동기를 별도로 설치하여야 하므로 냉방 효율이 좋지 못하다.However, when the exhaust gas array is used as a heat source for cooling rather than heating in the combined heat and power generation system, the cooling efficiency is not good because a heavy water absorption chiller having a low coefficient of performance must be separately installed.

또한, 배기가스를 열원으로 사용하는 배기가스 흡수식 냉동기도 사용 가능하지만 역시 성적계수가 높지 않아 효율이 좋지 않고, 앞서 언급된 바와 같이 중 온수 흡수식 냉동기가 필수적으로 설치되어야 한다.In addition, an exhaust gas absorption chiller using the exhaust gas as a heat source may be used, but also the efficiency is not good because the grade factor is not high, and as mentioned above, a heavy water absorption refrigerator should be installed as essential.

따라서, 위와 같은 문제로 인하여 현재 사용되고 있는 열 병합발전시스템으로는 지역냉방을 수행하기 어려워 에너지 이용에 대한 효율성을 더 높이는데 한계가 있다. Therefore, due to the above problems, it is difficult to perform district cooling with the thermally integrated power generation system currently used, and thus there is a limit to increasing the efficiency of energy use.

본 발명은 위와 같은 문제를 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 하나의 구동원을 통해 흡수식 장치와 압축식 장치를 운전시키고, 하절기에 지역냉방이 효율적으로 수행될 수 있도록 새로운 타입으로 개선된 흡수식 및 압축식 사이클을 이용한 열 병합발전시스템을 제공하는 것을 목적으로 한다. The present invention has been invented to solve the above problems, the object of the present invention is to improve the new type to operate the absorption device and the compression device through a single drive source, the district cooling can be performed efficiently in summer It is an object of the present invention to provide a combined heat generation system using absorption and compression cycles.

또한, 상기에서, 구동원으로부터 제공되는 전력이 전력 라인을 따라 압축기에 인가되는 것이 바람직할 것이다.Also, in the above, it would be desirable to apply power from the drive source to the compressor along the power line.

이하, 첨부된 도면을 참조하여 본 발명에 따른 흡수식 및 압축식 사이클을 이용한 열 병합발전시스템을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the combined heat and power generation system using the absorption and compression cycle according to the present invention.

도 1은 본 발명에 따른 흡수식 및 압축식 사이클을 이용한 열 병합발전시스템의 구성을 보여주는 개념도 이다.1 is a conceptual diagram showing the configuration of the combined heat and power generation system using the absorption and compression cycle according to the present invention.

도면에서 보는 바와 같이, 전력과 열을 생산하는 구동원(10)(예를 들면 가스엔진, 터빈, 연료전지)과 제1 열교환기(12) 간에 연결되는 고온 워터 자켓 냉각수 라인(14) 및 저온 워터 자켓 냉각수 라인(16)을 통하여 냉각수가 각각 순환하면서 구동원(10)을 식혀주고, 아울러 구동원(10)으로부터 제공되는 배기가스가 제1 열교환기(12)로 공급될 수 있도록 배기가스 공급라인(18)이 연결되어 있다.As shown in the figure, a high temperature water jacket coolant line 14 and low temperature water connected between a drive source 10 (eg, a gas engine, a turbine, a fuel cell) and a first heat exchanger 12 that produce power and heat Cooling water is circulated through the jacket cooling water line 16 to cool the driving source 10, and the exhaust gas supply line 18 may supply exhaust gas provided from the driving source 10 to the first heat exchanger 12. ) Is connected.

상기 제1 열교환기(12)와 흡수식 장치(A)의 고온 재생기(20) 간에는 배기가스 배열을 전달하기 위한 열 매체가 순환될 수 있도록 라인(22)을 통해 서로 연결된다. 이러한 상기 흡수식 장치(A)의 구성요소를 살펴보면 고온재생기(20), 응축기(24), 증발기(26), 흡수기(28)로 구성된다.The first heat exchanger 12 and the high temperature regenerator 20 of the absorbent device A are connected to each other via a line 22 so that a heat medium for transferring the exhaust gas array can be circulated. Looking at the components of the absorbent device (A) is composed of a high temperature regenerator 20, a condenser 24, an evaporator 26, an absorber 28.

상기 고온재생기(20)에는 배기가스가 배출될 수 있도록 배기 라인(30)이 형성되며, 응축기(24)와 증발기(26) 및 흡수기(28)에는 각각 발생 되는 열과 열 교환이 이루어지도록 열교환 라인(32,34,36)이 설치되어 된다. 특히 상기 증발기(26)에 증발 잠열과 열교환 되는 열교환 라인(34)은 제2 열교환기(38)를 순환할 수 있도록 설치된다.An exhaust line 30 is formed in the high temperature regenerator 20 to discharge the exhaust gas, and a heat exchange line is formed in the condenser 24, the evaporator 26, and the absorber 28 to generate heat and heat exchange, respectively. 32, 34, 36 are provided. In particular, the heat exchange line 34 is heat-exchanged with the latent heat of evaporation in the evaporator 26 is installed to circulate the second heat exchanger (38).

위와 같이 구성된 흡수식 장치(A)에서 흡수식 사이클에 대한 흐름과 일련의 동작과정은 일반적인 흡수식 장치 및 흡수식 사이클의 흐름과 동일하므로 생략한다.In the absorption device A configured as described above, the flow for the absorption cycle and the sequence of operations are the same as those of the general absorption device and the absorption cycle, and thus are omitted.

한편, 압축기(40), 응축기(42), 제1 팽창밸브(44), 제2 팽창밸브(46), 증발기(48)로 구성되는 압축식 장치(B)에서 제1 팽창밸브(44)와 제2 팽창밸브(46)를 연결하는 라인(50) 상에는 우회하는 형태로 연결되는 열교환 라인(52)이 상기 열교환 라인(34)을 흐르는 냉각수에 의해 열 교환될 수 있도록 제2 열교환기(38)와 연결되어 있다.On the other hand, in the compression device (B) consisting of the compressor 40, the condenser 42, the first expansion valve 44, the second expansion valve 46, the evaporator 48 and the first expansion valve 44 and On the line 50 connecting the second expansion valve 46, the second heat exchanger 38 may be heat exchanged by a cooling water flowing in the bypass heat exchange line 52 connected in a bypass form. Connected with

상기 압축식 장치(B)의 압축기(40)는 구동원(10)에서 제공되는 전력으로 가동될 수 있도록 전력 라인(54)을 통해 연결되어 있고, 상기 증발기(48)에는 증발 잠열과 열 교환되도록 열교환 라인(56)이 설치되어 있다.The compressor 40 of the compressed device B is connected via a power line 54 so as to be operated with the power provided from the drive source 10, and the evaporator 48 is heat exchanged to exchange heat with latent heat of evaporation. Line 56 is provided.

위와 같이 구성된 압축식 장치(B)에서 압축식 사이클에 대한 흐름과 일련의 동작과정은 일반적인 압축식 장치 및 압축식 사이클의 흐름과 동일하므로 생략한다.In the compression device B configured as described above, the flow for the compression cycle and the sequence of operations are the same as the flow of the general compression device and the compression cycle, and thus will be omitted.

위와 같이 구성된 흡수식 및 압축식 사이클을 이용한 열 병합발전시스템에 대한 일련의 동작과정을 하기에서 설명하기로 한다.A series of operating processes for the combined heat and power generation system using the absorption and compression cycle configured as described above will be described below.

가스엔진, 터빈, 연료전기 등과 같이 다양하게 구성되는 구동원(10)이 구동을 하게 되면서 전력과 고온의 배기가스가 발생 된다. 이때 이와 같이 발생 되는 전력 일부는 수용가로 공급되고, 일부 전력은 전력 라인(54)을 통해 압축장치(B)의 압축기(40)를 구동시켜 압축식 사이클에 대한 일련의 동작을 수행하게 된다.As the driving source 10, which is configured in various ways, such as a gas engine, a turbine, and a fuel electric machine, is driven, power and high temperature exhaust gas are generated. At this time, some of the generated power is supplied to the customer, and some of the power is driven through the power line 54 to drive the compressor 40 of the compression device B to perform a series of operations for the compression cycle.

한편, 상기 배기가스는 배기가스 공급라인(18)을 통해 제1 열교환기(12)로 공급되고, 배기가스의 배열과 열교환 되어 고온을 형성하는 열매체가 고온 재생기(20)로 공급되면서 흡수식 사이클에 대한 일련의 동작을 수행하게 된다. On the other hand, the exhaust gas is supplied to the first heat exchanger 12 through the exhaust gas supply line 18, and the heat medium, which is heat-exchanged with the arrangement of the exhaust gas to form a high temperature, is supplied to the high temperature regenerator 20 in the absorption cycle. Will perform a series of actions on the.

먼저, 흡수식 장치(A)의 흡수식 사이클을 간략히 살펴보면, 고온 재생기(20)에서는 제1 열교환기(12)로부터 열교환 되어 전달되는 고온의 열 매체가 흡수액을 가열시켜 고온의 냉매 증기와 고농축 용액으로 분리시키며 이와 같이 분리된 고온의 냉매 증기는 응축기(24)로 공급된다.First, briefly looking at the absorption cycle of the absorption device (A), in the high temperature regenerator 20, the high temperature heat medium transferred by heat exchange from the first heat exchanger 12 heats the absorption liquid to separate the high temperature refrigerant vapor and the high concentration solution. The high temperature refrigerant vapor thus separated is supplied to the condenser 24.

상기 응축기(24)로 공급된 고온의 증기 냉매는 응축되면서 저온의 액체 냉매로 변환되어 증발기(26)로 공급된다.The hot steam refrigerant supplied to the condenser 24 is condensed and converted into a low temperature liquid refrigerant and supplied to the evaporator 26.

상기 증발기(26)에서 증발한 냉매 증기는 흡수기(28)로 흡수되어 고온재생기(20)에서 농축한 흡수액에 흡수되고, 다시 고온 재생기(20)로 공급되는 일련의 과정을 반복하게 된다. The refrigerant vapor evaporated in the evaporator 26 is absorbed by the absorber 28, absorbed by the absorbed liquid concentrated in the high temperature regenerator 20, and then supplied to the high temperature regenerator 20.

위와 같이 흡수식 사이클이 진행되는 동안 흡수식 장치(A)의 증발기(26)와 제2 열교환기(38) 간에 설치된 열교환 라인(34)을 순환하는 냉각수는 저온을 형성하게 되는데, 통상 12℃로 들어가 증발 잠열과 열교환 후 7℃로 나오게 된다. The cooling water circulating in the heat exchange line 34 installed between the evaporator 26 and the second heat exchanger 38 of the absorbent device A during the absorption cycle as described above forms a low temperature. After latent heat and heat exchange, it comes out at 7 ℃.

한편, 상기 압축식 장치(B)의 압축식 사이클을 간략히 살펴보면, 상기에서 언급되었듯이 구동원(10)으로부터 제공되는 일부 전력에 의하여 압축기(40)가 구동을 하게 되면서 고온 고압을 형성하는 냉매 증기는 응축기(42)를 통해 응축되어 냉매액으로 변환된다.On the other hand, briefly looking at the compression cycle of the compression device (B), as mentioned above, the refrigerant vapor to form a high temperature and high pressure while the compressor 40 is driven by some power provided from the drive source 10 is It is condensed through the condenser 42 and converted into a refrigerant liquid.

상기 응축기(42)를 통과한 냉매액은 제1 팽창밸브(44)를 통과하면서 라인(50)을 따라 제2 팽창밸브(46)로 이송되는데, 이때 상기 제1 팽창밸브(44)를 통과하면서 증기로 변화된 일부 냉매 증기가 열교환 라인(52)을 따라 흐르게 된다.The refrigerant liquid passing through the condenser 42 is transferred to the second expansion valve 46 along the line 50 while passing through the first expansion valve 44, while passing through the first expansion valve 44. Some refrigerant vapor, which has been converted to steam, flows along the heat exchange line 52.

그에 따라 상기 제 2열교환기(38)와 증발기(26) 간에 연결된 열교환 라 인(34)으로 흐르는 냉각수에 의해 열을 빼앗기는 열 교환을 통해 응축되며, 응축된 냉매액은 라인(50)을 따라 흐르는 나머지 냉매액과 합쳐져 제2 팽창밸브(46)로 모두 공급된다. Thereby condensed through heat exchange to lose heat by the cooling water flowing into the heat exchange line 34 connected between the second heat exchanger 38 and the evaporator 26, the condensed refrigerant liquid flows along the line 50. Combined with the remaining refrigerant liquid and supplied to the second expansion valve 46.

상기 제2 팽창밸브(46)를 통과한 냉매액은 증발기(48)로 공급되면서 증발하게 되는데, 이때 상기 증발기(48)에서 열교환 라인(56)을 따라 순환하는 냉각수와 열교환을 하게 되어 냉각수가 저온을 형성하게 되고, 이와 같이 열 교환된 저온의 냉각수는 수용가로 공급되어 냉방을 수행하게 된다.The refrigerant liquid passing through the second expansion valve 46 is evaporated while being supplied to the evaporator 48. At this time, the refrigerant liquid exchanges heat with the cooling water circulating along the heat exchange line 56 in the evaporator 48 so that the cooling water has a low temperature. The low temperature cooling water exchanged as described above is supplied to the consumer to perform cooling.

도 2a 및 도 2b에서 보는 바와 같이 앞서 설명된 압축식 사이클과, 이에 대한 상태를 p-h선도를 통해 살펴보면, 압축기(40)를 통해 압축된 고온 고압의 냉매증기(b)는 응축기(42)를 지나면서 응축되어 냉매액(c)이 된다.2A and 2B, the above-described compression cycle, and the state thereof, are shown in the ph diagram, and the high temperature and high pressure refrigerant vapor b compressed through the compressor 40 passes through the condenser 42. While condensing to form the refrigerant liquid c.

이러한, 상기 냉매액(c)은 제1 팽창밸브(44)를 통과하면서 일부 형성되는 냉매 증기(d)가 흡수식 장치(A)의 증발기(26)와 제2 열교환기(38)를 순환하는 열교환 라인(34)의 냉각수에 의해 응축되어 냉매액(e)으로 변환된다. The refrigerant liquid c is a heat exchanger through which the refrigerant vapor d partially formed while passing through the first expansion valve 44 circulates through the evaporator 26 and the second heat exchanger 38 of the absorption device A. It is condensed by the cooling water of the line 34 and converted into the refrigerant liquid e.

변환된 상기 냉매액(e)은 제1 팽창밸브(44)를 통과한 나머지 냉매액과 다시 합쳐져 제2 팽창밸브(46)를 통과하게 되며, 이와 같이 통과한 냉매액(f)은 증발기(48)에 들어가 증발하면서 열교환 라인(56)으로 흐르는 냉각수의 온도를 급격히 낮추게 되어 냉방을 효율적으로 수행할 수 있게 된다. 이 후 증발기(48)을 통과한 냉매액(a)는 다시 압축기(40)으로 회수되는 순환과정을 반복하게 된다.The converted refrigerant liquid e is combined with the remaining refrigerant liquid passing through the first expansion valve 44 to pass through the second expansion valve 46, and the refrigerant liquid f thus passed is evaporator 48. The temperature of the cooling water flowing into the heat exchange line 56 is rapidly lowered while entering the evaporation, so that cooling can be efficiently performed. After that, the refrigerant liquid a having passed through the evaporator 48 repeats the circulation process which is recovered to the compressor 40 again.
