일반적으로, 유기랭킨사이클(ORC : Organic Rankine Cycle)은 유기매체를 작동유체로 사용하는 랭킨사이클(Rankin Cycle)로서 비교적 저온의 온도 범위 (60?200℃)의 열원을 회수하여 전기를 생산하는 시스템으로, 저온에서 고압의 기체를 생산하여 터빈을 구동하여야하는 ORC 시스템의 특성상 작동유체로는 비등점이 낮고, 증발압력이 높은 프레온 계열의 냉매를 사용한다.In general, ORC (Organic Rankine Cycle) is a Rankine cycle that uses organic media as a working fluid, a system that generates electricity by recovering heat sources in a relatively low temperature range (60 to 200 ° C). Due to the nature of the ORC system, which is required to produce high pressure gas at low temperature to drive a turbine, a freon-based refrigerant having a low boiling point and a high evaporation pressure is used as a working fluid.

이하, 첨부한 도면을 참조하여 본 발명에 따른 냉방 및 난방용수를 생산하는 ORC 터보발전 시스템을 자세히 살명한다.Hereinafter, an ORC turbo power generation system for producing cooling and heating water according to the present invention will be described in detail with reference to the accompanying drawings.

도시된 바와 같이, 본 발명의 ORC(유기랭킨사이클, Organic Rankine Cycle) 터보발전 시스템은 증발기(10), 터빈(20), 응축기(30), 응축탱크(40), 펌프(50), 예열기(50), 과열기(60)를 구비한다.As shown, ORC (Organic Rankine Cycle) turbo power generation system of the present invention is an evaporator 10, turbine 20, condenser 30, condensation tank 40, pump 50, preheater ( 50), and a superheater 60.

전술한 바와 같이, 증발기(10)는 작동유체에 열을 전달하여 기체로 상변화시키고, 터빈(20)은 작동유체의 열에너지를 기계적 에너지로 변환시킨다.As described above, the evaporator 10 transfers heat to the working fluid to phase change into a gas, and the turbine 20 converts the thermal energy of the working fluid into mechanical energy.

응축기(30)는 터빈(20)에서 나온 작동유체를 액체로 응축시켜 응축탱크(40)로 제공하며, 펌프(50)는 응축탱크(40)의 작동유체를 증발기(10)로 공급한다. The condenser 30 condenses the working fluid from the turbine 20 into a liquid and provides it to the condensation tank 40, and the pump 50 supplies the working fluid of the condensation tank 40 to the evaporator 10.

예열기(60)는 펌프(50)와 증발기(10) 사이에 위치하며 펌프(40)에서 공급된 작동유체를 제공받아 상기 증발기(10)에서 작동유체를 효과적으로 가열하도록 작동유체를 예열한다. 과열기(70)는 증발기(10)에서 증발한 작동유체의 온도를 필요한 온도까지 승온시킨다.The preheater 60 is located between the pump 50 and the evaporator 10 and receives the working fluid supplied from the pump 40 to preheat the working fluid to effectively heat the working fluid in the evaporator 10. The superheater 70 raises the temperature of the working fluid evaporated in the evaporator 10 to the required temperature.

한편, 응축기(30)는 겨울철에 외부의 난방용 물과 열교환되고, 여름철 흡수식 냉동기와 열교환된다. 응축기(30)의 일측에는 난방용 물 또는 흡수식 냉동기의 냉매가 공급되는 유입부(31)가 형성되고, 타측에는 열교환된 고온의 난방용수의 흡수식 냉동기의 냉매가 배출되는 배출부(33)가 형성된다. 유입부(31)의 일측에는 외부의 난방용 물과 흡수식 냉동기(80)의 냉매를 계절별로 선택적으로 공급되도록 제1제어밸브(32)가 형성된다. 배출부(33)의 일측에는 배출되는 겨울철에는 난방용수를 외부로 공급하고, 여름철에는 흡수식 냉동기(80)의 냉매를 다시 흡수식 냉동기로 공급하는 제2제어밸브(34)가 형성된다.On the other hand, the condenser 30 is heat exchanged with the external heating water in winter, heat exchanger with the summer absorption chiller. One side of the condenser 30 is formed with an inlet 31 for supplying the heating water or the refrigerant of the absorption chiller, and the other side is formed with an outlet 33 for discharging the refrigerant of the heat exchanger of the high temperature heating water. . The first control valve 32 is formed at one side of the inlet part 31 to selectively supply the external heating water and the refrigerant of the absorption chiller 80 according to seasons. One side of the discharge part 33 is provided with a second control valve 34 for supplying the heating water to the outside in the winter discharged, and in the summer to supply the refrigerant of the absorption-type refrigerator 80 to the absorption-type refrigerator again.

본 발명의 다른 실시예에 따른 응축기(30)는 겨울철에 외부의 난방용 물과 열교환되는 제1응축부(35)와 여름철 흡수식 냉동기와 열교환되는 제2응축부(36)가 형성된다.Condenser 30 according to another embodiment of the present invention is formed with a first condensation unit 35 for heat exchange with the external water for heating in winter and a second condensation unit 36 for heat exchange with the summer absorption chiller.

제1응축부(35)는 셀-튜브 열교환기, 판형 열교환기 등을 이용하여 증발기에서 배출되는 고온고압의 작동유체와 외부에서 유입된 낮은 온도의 물이 서로 열교환할 수 있도록 구성된다. 이에 따라 응축기로 공급된 고온고압의 작동유체는 외부에서 유입된 물과 열교환되면서 온도가 낮아지면서 응축탱크(40)로 공급되고, 외부의 물은 고온으로 배출되어 난방용으로 사용될 수 있다.The first condenser 35 is configured such that the high temperature and high pressure working fluid discharged from the evaporator and the low temperature water introduced from the outside may exchange heat with each other using a cell-tube heat exchanger or a plate heat exchanger. Accordingly, the high temperature and high pressure working fluid supplied to the condenser is supplied to the condensation tank 40 while the temperature is lowered while heat exchanged with water introduced from the outside, and the external water may be discharged at a high temperature and used for heating.

제2응축부(36)는 터빈에서 배출되는 고온고압의 작동유체와 흡수식 냉동기의 흡수액과 열교환되어 흡수식 냉동기(80)의 열원으로 사용된다. 이에 따라 제2응축부로 공급된 고온고압의 작동유체는 외부의 흡수식 냉동기(80)와 열교환되면서 온도가 낮아지면서 응축탱크(40)로 공급되고, 흡수식 냉동기(80)의 흡수액이 가열된다. 제2응축부(36)는 제1응축부와 동일한 열교환기를 사용할 수 있다.The second condenser 36 is used as a heat source of the absorption chiller 80 by heat-exchanging with the high temperature and high pressure working fluid discharged from the turbine and the absorption liquid of the absorption chiller. Accordingly, the high-temperature, high-pressure working fluid supplied to the second condensation part is supplied to the condensation tank 40 while the temperature is lowered while heat-exchanging with the external absorption chiller 80, and the absorption liquid of the absorption chiller 80 is heated. The second condenser 36 may use the same heat exchanger as the first condenser.

흡수식 냉동기(80)는 주지하는 바와 같이 기체의 액체에 대한 흡수성을 이용하는 것으로 통상 냉매를 응축기(30 또는 제2응축부(32))로 공급하여 증발시키는 재생부(81), 증발된 냉매를 응축하는 응축부(82), 냉매가 증발하면서 외부의 공기와 열교환하는 증발부(83) 및 열교환된 냉매가 다시 흡수되는 흡수부(84)로 구성되며 냉매로는 물이 사용되고 흡수액으로 리튬브로마이드(Litbium Bromide : LiBr) 또는 암모니아(NH3)가 사용된다. 이러한 냉방시에는 증발부(83)에서 냉매인 물과 외부공기가 열교환하여 차가운 공기를 냉방용으로 사용하게 된다.Absorption refrigeration unit 80 is to use the absorbency of the liquid to the gas, as is well known in the regeneration unit 81 to supply the refrigerant to the condenser (30 or the second condensing unit 32) and evaporate, the condensed evaporated refrigerant Condensation unit 82, the evaporator 83 for heat exchange with the outside air while the refrigerant evaporates, and the absorption unit 84 is absorbed by the heat-exchanged refrigerant again, the water is used as the refrigerant and lithium bromide (Litbium) Bromide: LiBr) or ammonia (NH 3 ) is used. In such cooling, the evaporator 83 exchanges water, which is a refrigerant, with external air, to use cold air for cooling.

흡수식 냉동기를 자세히 살펴보면, 흡수액이 흡수부(84) 상부의 트래이로부터 흡수부(84) 내의 냉각수 전열관위로 떨어지며 엘리미네이터 사이로 넘어온 수증기를 흡수하여 흡수부(84) 바닥에 모이게 된다. 모여진 흡수액은 응축기(30 또는 제2응축부(32))의 작동유체와 열교환되면서 가열되어 물이 증발하며 농도가 더 짙은 흡수액으로 만든 뒤 다시 흡수부(84)로 되돌아간다. 이와 같은 순환과정을 거쳐 흡수액이 다시 수증기를 흡수하여 같은 방식으로 계속 순환된다. Looking at the absorption chiller in detail, the absorbent liquid is dropped from the tray on the upper portion of the absorber 84 to the coolant heat transfer tube in the absorber 84 and absorbs the water vapor passed between the eliminator and collects at the bottom of the absorber 84. The collected absorbent liquid is heated while exchanging heat with the working fluid of the condenser 30 or the second condenser 32 to evaporate water to make the absorbent liquid having a higher concentration, and then return to the absorbent unit 84 again. Through this circulation process, the absorbent liquid absorbs water vapor again and continues to circulate in the same manner.

한편 냉매인 물의 순환은 증발부(83)에서 물이 가장 증발하기 쉬운 조건인 밀폐된 진공상태 즉 증발기 내부압력 약 6.5mmHg와 약 4℃ 온도를 유지시키면 증발하면서 냉각수의 증발잠열을 빼앗아감으로서 전열관내에서 흐르는 외부공기를 냉방에 필요한 저온의 냉방공기로 만들게 된다. 이때 증기형태가 된 수증기는 흡수액에 의해 강력하게 흡수되어져 재생부(81)까지 흡수액과 함께 섞여 운반된다. 재생부(81)에서 응축기(30 또는 제2응축부(32))의 작동유체와 열교환되면서 가열되어 수증기로 증발되어 엘리미네이터 사이로 넘어 응축부로 유입되어 냉각탑에서 냉각된 냉각수와 열교환되면서 물로 응축된다. 응축부의 냉매는 증발부(83)로 회수되어 다시 상기와 같은 순서로 재순환 되는 냉매 싸이클을 형성한다.
On the other hand, the circulation of water, which is a refrigerant, is transferred to the evaporator 83 in a closed vacuum state in which water is most likely to evaporate. The outside air flowing in the pipe is made into the low temperature cooling air required for cooling. At this time, the water vapor in the form of steam is strongly absorbed by the absorbent liquid, and is mixed with the absorbent liquid and transported to the regeneration unit 81. Heat is exchanged with the working fluid of the condenser 30 or the second condenser 32 in the regeneration unit 81 and is evaporated into water vapor, flows between the eliminators, flows into the condenser, and condenses into water as it heats with the cooling water cooled in the cooling tower. . The refrigerant in the condensation unit is recovered to the evaporation unit 83 to form a refrigerant cycle that is recycled in the above order.
