Description

압축식 및 흡수식을 이용한 히트펌프 시스템{Heat Pump System Using Compression Type and Absorption Type}Heat Pump System Using Compression Type and Absorption Type

본 발명은 압축식 및 흡수식을 이용한 히트펌프 시스템에 관한 것으로, 더욱 상세하게는 압축식 히트펌프에 흡수식 사이클의 장점을 적용하여 일반적인 히트 펌프에서 얻을 수 없었던 난방용 고온수를 얻을 수 있도록 한다. 아울러 난방수와 열교환하게 되는 혼합 냉매의 비가역 손실을 줄여 시스템 효율을 향상시킬 수 있도록 한다.
The present invention relates to a heat pump system using a compression type and an absorption type, and more particularly, by applying the advantages of an absorption cycle to a compression heat pump, it is possible to obtain high temperature water for heating that cannot be obtained in a general heat pump. In addition, it is possible to improve the system efficiency by reducing the irreversible loss of the mixed refrigerant to be exchanged with the heating water.

일반적으로, 증기 압축식 히트펌프 또는 흡수식 히트 펌프를 이용하여 90℃ 이상 고온수를 얻는 방법으로 통상 보일러 혹은 가열기와 같은 보조 열원을 히트 펌프 시스템에 적용하고 있다. 그러나 추가적인 보조 열원의 적용에 의해 시스템 의 성능계수 저하가 필연적으로 발생하게 됨으로써 전체적으로 시스템 효율이 좋지 못하다.In general, an auxiliary heat source such as a boiler or a heater is generally applied to a heat pump system by using a vapor compression heat pump or an absorption heat pump to obtain hot water of 90 ° C. or higher. However, the application of additional auxiliary heat sources inevitably leads to a decrease in the system's coefficient of performance, resulting in poor overall system efficiency.

특히, 증기 압축식 히트 펌프에서는 난방수와 열교환하게 되는 냉매를 고온으로 형성하기 위해 여러 개의 압축기를 적용하는 다단 압축 방식이 채택될 수 있으나, 실제로는 압축기의 성능 및 압축비 한계가 있다. 그와 함께 막대한 시설비용도 소요되어 실용적이지 못한 단점이 있고, 예컨대 여러 개의 압축기가 적용될 경우 가역 손실이 크게 작용하여 시스템의 효율이 저하되는 문제도 발생한다.In particular, in the steam compression heat pump, a multi-stage compression method using multiple compressors may be adopted to form a refrigerant that is heat-exchanged with the heating water at a high temperature. Along with this, a huge facility cost is also required, which is not practical. For example, when a plurality of compressors are applied, reversible losses are large, resulting in a problem that the efficiency of the system is lowered.

이에 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 압축식 히트펌프에 흡수식 사이클의 장점을 적용하여 일반적인 히트 펌프에서 얻을 수 없는 난방용 고온수를 얻을 수 있도록 하고, 아울러 난방수와 열교환하게 되는 혼합 냉매의 비가역 손실을 줄임으로써 시스템의 효율 향상시킬 수 있는 압축식 및 흡수식을 이용한 히트펌프 시스템을 제공하는데 그 목적이 있다.

A suction solution line connected to join a refrigerant conveyed from the compressor; In the cooling mode, the absorbent solution passing through the three-way valve is connected to pass through the desorber in a state of forming a mixed refrigerant to meet the refrigerant at the second absorbing solution confluence point of the refrigerant line; Provided is a heat pump system.

또한, 상기 흡수 용액이 지나가는 제1 열교환기와 삼방밸브 사이에 제2 열교환가 설치되고, 상기 가스엔진의 배기가스 열교환기를 지나 제2 열교환기를 통과하면서 제2 열교환기에서 흡수 용액과 열교환을 수행 후 가스엔진으로 유입되는 냉각수 라인을 더 포함하여 구성되는 압축식 및 흡수식을 이용한 히트펌프 시스템이 제공된다.

이와 같이, 본 발명에 따른 압축식 및 흡수식을 이용한 히트펌프 시스템을 사용하게 되면, 보일러 혹은 가열기와 같은 보조 열원이나 압축기의 추가 적용 없이도 높은 온도의 난방수를 얻을 수 있는 효과를 기대할 수 있다.As such, when the heat pump system using the compression type and the absorption type according to the present invention is used, an effect of obtaining high temperature heating water without additional application of an auxiliary heat source or a compressor such as a boiler or a heater can be expected.

그와 더불어 난방수와 열교환하는 혼합냉매가 열교환 과정 중 상변화가 없어 비가역 손실이 최소화 되고, 그로 인해 시스템의 효율을 향상시킬 수 있는 효과도 기대할 수 있다.
In addition, the mixed refrigerant heat-exchanging with the heating water does not have a phase change during the heat exchange process, thereby minimizing irreversible losses, thereby improving the efficiency of the system.

도 1은 본 발명에 따른 압축식 및 흡수식을 이용한 히트펌프 시스템이다.1 is a heat pump system using a compression and absorption in accordance with the present invention.

이하, 본 발명을 실시하기 위한 구체적인 내용을 첨부된 예시도면에 의거 상세하게 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1에서는 본 발명에 따른 압축식 및 흡수식을 이용한 히트펌프 시스템이 도시되어 있다. 설명에 앞서, 난방 모드시 냉매 및 흡수 용액 순환 경로를 기준으로 하여 설명한다. 참고로 냉매는 암모니아이고, 흡수 용액은 물이 사용된다.1 shows a heat pump system using compression and absorption in accordance with the present invention. Prior to the description, description will be made based on the refrigerant and the absorption solution circulation paths in the heating mode. For reference, the refrigerant is ammonia and the absorption solution is water.

도면에 도시된 바와 같이, 먼저 히트펌프 시스템(10)의 구성을 냉매 라인(22)을 따라 살펴보면, 어큐뮬레이터(12)에 존재하는 냉매 기체는 가스엔진(14)의 구동력으로 구동하게 되는 압축기(16)를 거쳐 오일분리기(18) 및 사방밸브(38)을 통과 후 업소버(20)를 지나게 된다. 이때 오일분리기(18)와 업소버(20)를 지나가는 냉매 라인(22)에는 후술하는 흡수 용액 라인(24)이 제1 흡수액 합류지점(P1)에서 만나는 상태로 연결되어 있어, 냉매와 흡수 용액이 제1 흡수액 합류지점(P1)에서 만나 혼합냉매를 형성하게 된다. 이러한 혼합냉매가 업소버(20)를 통과하게 된다.As shown in the figure, first, the configuration of the heat pump system 10 along the refrigerant line 22, the refrigerant gas present in the accumulator 12 is driven by the driving force of the gas engine 14 (16) After passing through the oil separator 18 and the four-way valve 38 passes through the absorber 20. At this time, the refrigerant line 22 passing through the oil separator 18 and the absorber 20 is connected in a state where the absorption solution line 24 described later meets at the first absorption liquid confluence point P1, whereby the refrigerant and the absorption solution are formed. 1 is met at the absorbing liquid confluence point (P1) to form a mixed refrigerant. This mixed refrigerant passes through the absorber 20.

또한 상기 업소버(20)에는 난방수가 흐르도록 난방수 라인(28)이 설치되어 있어 업소버(20)를 통과하는 혼합냉매는 난방수와 열교환하게 되고, 그로 인해 난방수는 고온을 형성하게 된다.In addition, the absorber 20 is provided with a heating water line 28 so that the heating water flows, so that the mixed refrigerant passing through the absorber 20 exchanges heat with the heating water, and thus the heating water forms a high temperature.

상기 업소버(20)를 통과한 혼합냉매는 제1 팽창밸브(30a)를 거쳐 제1 열교환기(32)를 통과하게 되고, 제1 열교환기(32)를 통과한 혼합냉매는 제2 팽창밸브(30b)를 지나 냉수가 흐르도록 냉수 라인(34)이 설치된 디소버(36)를 통과 후 사방밸브(38)를 거쳐 어큐뮬레이터(12)로 회수되는 구성을 가진다.The mixed refrigerant passing through the absorber 20 passes through the first heat exchanger 32 through the first expansion valve 30a, and the mixed refrigerant passing through the first heat exchanger 32 passes through the second expansion valve ( After passing through the desorber 36 in which the cold water line 34 is installed so that the cold water flows through 30b), it is recovered to the accumulator 12 via the four-way valve 38.

한편, 히트펌프 시스템(10)의 구성을 용액 라인을 따라 살펴보면,어큐물레이터(12)에 존재하는 흡수 용액은 흡수 용액 펌프(40)와 사방밸브(42)를 순차적으로 거쳐 제1 열교환기(32) 및 제2 열교환기(44)를 순차적으로 지나게 된다. 참고로, 제1 열교환기(32)에서는 앞서 설명하였듯이 혼합냉매와 열교환을 하게 된다. On the other hand, looking at the configuration of the heat pump system 10 along the solution line, the absorbent solution present in the accumulator 12 is sequentially passed through the absorption solution pump 40 and the four-way valve 42 to the first heat exchanger ( 32) and second heat exchanger (44) in order. For reference, as described above, the first heat exchanger 32 performs heat exchange with the mixed refrigerant.

상기 제2 열교환기(44)를 통과한 흡수 용액은 사방밸브(42)와 삼방밸브(46)을 각각 거쳐 제1 흡수 용액 합류지점(P1)에서 냉매와 만나게 된다.The absorbent solution passing through the second heat exchanger 44 meets the refrigerant at the first absorbent solution confluence point P1 through the four-way valve 42 and the three-way valve 46, respectively.

냉방 모드시, 상기 삼방밸브(46)를 지나가는 흡수 용액이 냉매 라인(22)의 제2 흡수 용액 합류지점(P2)에서 냉매와 만나 혼합냉매를 형성하는 상태로 디소버(36)를 지나가도록 라인이 연결된다. In the cooling mode, the absorbent solution passing through the three-way valve 46 passes through the solver 36 in a state where the absorbent solution meets the refrigerant at the second absorption solution confluence point P2 of the refrigerant line 22 to form a mixed refrigerant. This is connected.

한편, 상기 가스엔진(14)을 식히기 위해 가스엔진(14)을 지나가는 냉각수 라인(50)은, 먼저 가스엔진(14)의 배기가스 열교환기(52)를 지나 제2 열교환기(44)를 통과하면서 제2 열교환기(44)를 지나가는 흡수 용액과 열교환을 수행 후 방열기(54)를 통과하면서 냉각되고, 방열기(54)를 통과한 냉각수는 냉각수 펌프(56)를 통해 가스엔진(14)으로 다시 유입되는 순환 구조로 구성된다.
Meanwhile, the coolant line 50 passing through the gas engine 14 to cool the gas engine 14 first passes through the exhaust gas heat exchanger 52 of the gas engine 14 and passes through the second heat exchanger 44. While performing the heat exchange with the absorbing solution passing through the second heat exchanger 44, and then cooled while passing through the radiator 54, the coolant passed through the radiator 54 is back to the gas engine 14 through the cooling water pump (56). It is composed of incoming circulation structure.

하기에서는 압축식 및 흡수식을 이용한 히트펌프 시스템의 동작 모드를 설명하기로 한다.
Hereinafter, the operation mode of the heat pump system using the compression type and the absorption type will be described.

[난방 모드][Heating Mode]

어큐물레이터(12)에 존재하는 냉매 기체는 압축기(16)를 통과하면서 고온 고압으로 형성된 후 오일분리기(18)와 사방밸브(38)를 순차적으로 거쳐 합류지점(P1)을 지나게 된다.The refrigerant gas present in the accumulator 12 is formed at a high temperature and high pressure while passing through the compressor 16, and then passes through the confluence point P1 through the oil separator 18 and the four-way valve 38 sequentially.

이와 동시에 어큐물레이터(12)에 존재하는 흡수 용액은 흡수 용액 펌프(40)를 통해 사방밸브(42)를 거쳐 제1 열교환기(32)를 지나가는 혼합냉매와 열교환하여 1차적으로 온도가 높아지는 상태로 된다.At the same time, the absorbent solution present in the accumulator 12 exchanges heat with the mixed refrigerant passing through the first heat exchanger 32 via the four-way valve 42 through the absorbent solution pump 40, thereby increasing the temperature first. It becomes

그리고, 상기 제1 열교환(32)을 통과한 흡수 용액은 제2 열교환기(44)를 지나게 되는데, 이때 배기가스 열교환기(52)를 통과하면서 고온으로 형성된 냉각수와 열교환하여 2차적으로 가열되는 상태가 됨으로써 더 높은 온도를 형성한 후 제1 흡수 용액(P1)에서 고온 고압의 냉매와 만나게 된다. 참고로, 상기 흡수 용액의 온도를 고온으로 형성시키는 이유는 냉매의 특성상 화학반응이 활발히 잘 일어나도록 하기 위함이다.In addition, the absorbent solution passing through the first heat exchanger 32 passes through the second heat exchanger 44. At this time, the absorbent solution passes through the exhaust gas heat exchanger 52 and heats with the coolant formed at a high temperature to be secondarily heated. By forming a higher temperature and then meet the high temperature and high pressure refrigerant in the first absorption solution (P1). For reference, the reason for forming the temperature of the absorbent solution at a high temperature is to allow the chemical reaction to occur actively due to the characteristics of the refrigerant.

따라서, 상기 제1 흡수 용액(P1)에서 냉매와 흡수 용액이 만나 화학 반응을 하게 되고, 그에 따라 높은 온도의 반응열(약 450℃ ~ 550℃)을 지닌 혼합냉매가 업소버(20)를 통과하게 된다. 그로 인해 업소버(20)를 지나가는 난방수와 열교환하게 되어 90℃ 이상의 난방수를 얻을 수 있게 된다.Therefore, in the first absorption solution P1, the refrigerant and the absorption solution meet and chemically react, and thus, a mixed refrigerant having a high temperature reaction heat (about 450 ° C. to 550 ° C.) passes through the absorber 20. . Therefore, the heat exchanger with the heating water passing through the absorber 20 is able to obtain the heating water of 90 ℃ or more.

그리고, 위와 같이 업소버(20)를 통과하는 혼합냉매는 난방수와의 열교환으로 인해 온도가 낮아진 상태이지만 반응열이 매우 높아 높은 온도를 형성하는 상태로 제1 팽창밸브(30a)를 통과하게 된다.In addition, the mixed refrigerant passing through the absorber 20 as described above passes through the first expansion valve 30a in a state where the temperature is lowered due to heat exchange with the heating water, but the reaction heat is very high to form a high temperature.

상기 제1 팽창밸브(30a)를 통과한 혼합냉매는 제1 열교환기(32)를 지나가게 되는데, 이때 제1 열교환기(32)를 통과는 흡수 용액과 열교환하여 흡수 용액의 온도를 높여주고 혼합냉매는 저온 저압을 형성하게 된다.The mixed refrigerant passing through the first expansion valve 30a passes through the first heat exchanger 32. At this time, the first refrigerant passes through the first heat exchanger 32 to exchange heat with the absorbent solution to increase the temperature of the absorbent solution and to mix the refrigerant. The refrigerant will form a low temperature low pressure.

그리고, 상기 제1 열교환기(32)를 통과한 저온 저압 혼합냉매는 제2 팽창밸브(30b)를 통과하면서 압력이 더 낮아진 상태로 디소버(36)를 지나가게 된다. 이때 디소버(36)를 지나가는 혼합냉매는 디소버(36)를 순환하는 냉수와 열교환하여 증발을 일으키게 되고, 이러한 증발에 의해 혼합냉매는 냉매 기체와 흡수 용액으로 분리되어 어큐뮬레이터(12)로 회수되는 순환을 반복하게 된다.In addition, the low temperature low pressure mixed refrigerant passing through the first heat exchanger 32 passes through the absorber 36 while the pressure is lowered while passing through the second expansion valve 30b. At this time, the mixed refrigerant passing through the desorber 36 causes evaporation by exchanging heat with cold water circulating through the desorber 36. The mixed refrigerant is separated into a refrigerant gas and an absorbing solution and recovered by the accumulator 12. The cycle will repeat.

어큐물레이터(12)에 존재하는 냉매 기체는 압축기를 통과하면서 고온 고압을 형성하게 되고, 압축기(16)를 통과한 냉매는 사방밸브(38)를 거쳐 제2 흡수 용액 합류지점(P2)을 지나가게 된다. 이와 동시에 어큐물레이터(12)에 존재하는 흡수 용액은 사방밸브(42)와 삼방밸브(46)를 각각 거쳐 제2 흡수 용액 합류지점(P2)에서 고온 고압을 형성하는 냉매와 만나게 된다.The refrigerant gas present in the accumulator 12 forms a high temperature and high pressure while passing through the compressor, and the refrigerant passing through the compressor 16 passes through the second absorbing solution confluence point P2 via the four-way valve 38. I will go. At the same time, the absorbent solution present in the accumulator 12 meets the refrigerant forming the high temperature and high pressure at the second absorbent solution confluence point P2 via the four-way valve 42 and the three-way valve 46, respectively.

위와 같이 제2 흡수 용액 합류지점(P2)에서 냉매와 흡수 용액이 만나게 되면 화학 반응을 일으키게 되는데, 이때 흡수 용액은 저온 저압을 형성하고 있어 높은 반응열을 형성하지 못하게 되고, 이러한 혼합냉매가 디소버(36)를 지나가는 동안 냉수에 의해 냉각되어 더 낮은 저온을 형성하게 된다.As described above, when the refrigerant and the absorbent solution meet at the second absorbent solution confluence point (P2), a chemical reaction occurs. At this time, the absorbent solution forms a low temperature and low pressure, and thus does not form a high reaction heat. As it passes 36) it is cooled by cold water to form lower temperatures.

그리고, 상기 디소버(36)를 통과한 혼합냉매는 제2 팽창밸브(30b)와 제1 열교환기(32) 및 제1 팽창밸브(30a)를 순차적으로 통과하면서 저온 저압을 형성하게 된다. 참고로, 냉방모드에서는 사방밸브(42)의 유로 전환에 따라 흡수 용액이 삼방밸브(46)를 거쳐 제2 흡수 용액 합류지점(P2)으로 흐르게 됨으로써 제1 열교환기(32)에서 흡수 용액과 열교환이 없는 상태가 된다.Then, the mixed refrigerant passing through the absorber 36 forms a low temperature low pressure while sequentially passing through the second expansion valve 30b, the first heat exchanger 32, and the first expansion valve 30a. For reference, in the cooling mode, the absorbent solution flows through the three-way valve 46 to the second absorbing solution confluence point P2 as the flow path of the four-way valve 42 changes, thereby exchanging heat with the absorbent solution in the first heat exchanger 32. There is no state.

상기 제1 팽창밸브(30a)를 통과하는 혼합냉매는 업소버(20)를 지나가는 난방수와 열교환하게 되어 난방수가 냉각됨으로써 냉방에 사용되는 냉각수를 얻게 된다.The mixed refrigerant passing through the first expansion valve 30a exchanges heat with the heating water passing through the absorber 20, thereby cooling the heating water to obtain cooling water used for cooling.

그리고, 위와 같이 업소버(20)를 통과하는 혼합냉매는 사방밸브(38)를 거쳐 어큐뮬레이터(12)로 회수되는 순환을 반복하게 된다.As described above, the mixed refrigerant passing through the absorber 20 is repeated through the four-way valve 38 to the accumulator 12.

따라서, 본 발명에 따른 압축식 및 흡수식을 이용한 히트펌프 시스템(10)을 사용하게 되면, 냉매와 흡수 용액의 화학반응으로 발생하는 높은 반응열을 이용하게 됨으로써, 보일러 혹은 가열기와 같은 보조 열원이나 압축기의 추가 적용 없이도 높은 온도의 난방수를 얻을 수 있게 된다. 특히 본 발명에 따른 압축식 및 흡수식을 이용한 히트펌프 시스템은 난방수와 열교환하는 혼합냉매가 열교환 과정 중 상변화 없어 비가역 손실이 최소됨으로써 시스템 효율도 향상된다.
