폐열원공급라인(12)을 통해 증발기(10)에 공급되는 폐열원은 증발기(10)를 통과하는 냉매가 열교환기 모양으로 굴곡되는 폐열원공급라인(12)과 접촉되면서 열에너지를 흡수하여 증기로 증발되고, 이 증기는 제1엘리미네이터(22)를 통과하여 흡수기(30)로 이동되고, 흡수기(30)를 통과하는 온수유입관(32)에 냉매가 접촉되면서 열에너지를 온수에 공급하게 된다.The waste heat source supplied to the evaporator 10 through the waste heat source supply line 12 is in contact with the waste heat source supply line 12 in which the refrigerant passing through the evaporator 10 is bent in the form of a heat exchanger, This vapor is passed through the first eliminator 22 to the absorber 30 and the refrigerant is brought into contact with the hot water inflow pipe 32 passing through the absorber 30 to supply heat energy to hot water .

이때, 농용액산포노즐부(52a)를 통해 흡수기(30) 내부에 산포되는 흡수액은 증발기(10) 및 흡수기(30) 내부의 압력 조건, 약400mmHg 정도의 고압에 의해 순간적으로 가열되면서 흡수기(30) 내부를 통과하는 온수유입관(32)에 접촉되어 섭씨125~135℃ 정도의 온수를 제공하게 된다.At this time, the absorption liquid scattered inside the absorber 30 through the concentrated solution scattering nozzle unit 52a is instantaneously heated by the high pressure of about 400 mmHg under the pressure condition inside the evaporator 10 and the absorber 30, The hot water is supplied to the hot water inflow pipe 32 passing through the inside of the hot water inflow pipe.

온수유입관(32)에 열에너지를 공급한 흡수액은 저온의 희농액으로 농도가 낮아져 희용액관(36)을 따라 배출되고, 저온재생기(70)에 공급되어 증발기(10)로부터 연장되는 폐열원환수라인(14)과 접촉되면서 2차로 폐열원으로부터 열에너지를 흡수하게 된다.The absorption liquid which has supplied the thermal energy to the hot water inflow pipe 32 is discharged along the dilution solution pipe 36 because the concentration thereof is lowered by the low temperature dilution liquid and is supplied to the low temperature regenerator 70 to be discharged from the evaporator 10 The heat is absorbed from the waste heat source in a secondary way while being in contact with the line 14.

폐열원공급라인(12)에는 일측으로 분기되는 폐열원분기관(12a)이 설치되는데, 폐열원분기관(12a)은 고온재생기(50)를 통과하면서 저온재생기(70)로부터 공급되는 흡수액과 열교환을 행하게 되고, 고온재생기(50)에서 배출되는 흡수액은 농용액관(52)을 따라 흡수기(30)에 공급되어 온수유입관(32)과 열교환되면서 온수의 가열이 효과적으로 이루어지도록 한다.The waste heat source orifice 12a is branched to one side of the waste heat source supply line 12. The waste heat source orifice 12a passes through the high temperature regenerator 50 and performs heat exchange with the absorption liquid supplied from the low temperature regenerator 70 And the absorbing liquid discharged from the high temperature regenerator 50 is supplied to the absorber 30 along the thickener tube 52 to be heat-exchanged with the hot water inflow pipe 32 so that the heating of the hot water is effectively performed.

고온재생기(50)에서 증발된 증기는 제2엘리미네이터(24)를 통과하여 보조흡수기(54)에 공급되고, 보조흡수기(54)를 통과하는 냉각수라인(56) 및 냉각수라인(57)과 접촉되어 냉각수와 열교환되며 냉각된다.The vapor evaporated in the high temperature regenerator 50 passes through the second eliminator 24 and is supplied to the secondary absorber 54 and the cooling water line 56 and the cooling water line 57 passing through the secondary absorber 54 Exchanged with the cooling water, and cooled.

응축기(76)에서 냉각되는 냉매는 냉매공급관(76a)을 통해 증발기(10)에 공급되어 냉매가 폐열원공급라인(12)과 접촉되면서 폐열원으로부터 열에너지를 흡수하여 증발되고, 흡수기(30)로 이동되면서 온수를 가열하게 된다.The refrigerant cooled in the condenser 76 is supplied to the evaporator 10 through the refrigerant supply pipe 76a so that the refrigerant absorbs heat energy from the waste heat source while being in contact with the waste heat source supply line 12, The hot water is heated while being moved.

본 실시예는, 상기한 바와 같이 증발기(10)에서 폐열원으로부터 열에너지를 흡수하여 흡수기에 공급하고, 고온재생기(50) 및 저온재생기(70)에서 폐열원으로부터 열에너지를 제공받아 흡수기(30)에서 배출되는 흡수액을 가열하여 흡수액의 농도를 높이는 재생공정이 진행된다.In this embodiment, as described above, the evaporator 10 absorbs heat energy from the waste heat source and supplies it to the absorber. In the high temperature regenerator 50 and the low temperature regenerator 70, heat energy is supplied from the waste heat source, The regeneration step of heating the discharged absorbing liquid to increase the concentration of the absorbing liquid proceeds.

또한, 저온재생기(70)에서 압송되는 흡수액은, 고온재생기(50)로 공급되어 폐열원에 의해 가열되어 농도가 높은 흡수액 농용액으로 변환되고, 흡수액 농용액은, 흡수기(30)에 제공되면서 고압에 의해 고온으로 가열되면서 산포된다.The absorbing liquid fed by the low temperature regenerator 70 is supplied to the high temperature regenerator 50 and heated by the waste heat source to be converted into the absorbing liquid concentrated liquid having a high concentration and the absorbent liquid concentrated solution is supplied to the absorber 30, And is dispersed while being heated to a high temperature.

따라서 흡수기(30) 내부에서는, 증발기(10)에서 공급되는 고온의 증기와, 농용액산포노즐부(52a)에서 산포되는 고온의 흡수액이 온수유입관(32)에 접촉되어 고온의 온수를 제공하게 된다.Therefore, in the absorber 30, the high-temperature steam supplied from the evaporator 10 and the high-temperature absorbing liquid dispersed in the concentrated solution scattering nozzle portion 52a come into contact with the hot water inflow pipe 32 to provide hot water of high temperature do.

또한, 본 실시예의 농용액관(52)은 희용액관(36)에 설치되는 고온열교환기(36a)를 통과하므로 흡수기(30)에서 배출되는 흡수액과, 고온재생기(50)에서 배출되는 흡수액 사이에서 열교환이 이루어지게 되고, 상대적으로 고온으로 배출되는 흡수기(30)의 흡수액으로부터 열에너지를 흡수하여 고온재생기(50)의 흡수액이 가열되어 흡수기(30)에 공급된다.Since the concentrated liquid pipe 52 of the present embodiment passes through the high temperature heat exchanger 36a installed in the dilution pipe 36 and is sucked between the absorbing liquid discharged from the absorber 30 and the absorbing liquid discharged from the high temperature regenerator 50 The absorbing liquid of the high temperature regenerator 50 is heated and is supplied to the absorber 30 by absorbing heat energy from the absorbing liquid of the absorber 30 discharged at a relatively high temperature.

따라서 흡수기(30)에서 열교환되지 않고 배출되는 흡수액의 열에너지를 다시 흡수기(30)로 순환시키는 회수 작용을 행하게 된다.Therefore, the absorbing unit 30 performs the recovery operation of circulating the heat energy of the absorbing liquid discharged without being heat-exchanged to the absorber 30 again.

또한, 중간용액관(72)은 희용액관(36)에 설치되는 저온열교환기(36b)를 통과하게 되므로 흡수기(30)에서 배출되는 흡수액의 열에너지를 저온재생기(70)에서 배출되는 흡수액과 열교환시켜 2차에 걸쳐 흡수기(30)에서 배출되는 흡수액으로부터 열에너지를 회수시키는 작용을 행하게 된다.Since the intermediate solution tube 72 passes through the low temperature heat exchanger 36b installed in the dilution tube 36, the heat energy of the absorbing liquid discharged from the absorber 30 is exchanged with the absorption liquid discharged from the low temperature generator 70 So that the absorbing liquid discharged from the absorber 30 is recovered from the absorbing liquid.

흡수기(30)에는 농용액관(52)에 연결되어 흡수액을 흡수기(30) 내부 전체에 산포시키는 농용액산포노즐부(52a)가 설치되므로 흡수기(30) 내부에 설치되는 온수유입관(32)의 열교환기 전체에 냉매가 고르게 접촉될 수 있게 되고, 증발기(10)의 내부에는 냉매산포노즐부(16a)가 설치되므로 증발기(10)에 공급되는 냉매가 냉매순환관(16)을 따라 재공급될 때에 폐열원공급라인(12)에 연결되는 코일 전체에 냉매산포노즐부(16a)에서 산포되는 냉매가 고르게 분사될 수 있게 된다.The absorber 30 is connected to the concentrated solution tube 52 to supply the concentrated solution spray nozzle part 52a for dispersing the absorbed solution to the entire inside of the absorber 30. The hot water inflow pipe 32, The refrigerant can be uniformly supplied to the entire heat exchanger of the evaporator 10 and the refrigerant dispersing nozzle unit 16a is installed in the evaporator 10 so that the refrigerant supplied to the evaporator 10 can be supplied again along the refrigerant circulation pipe 16 The refrigerant dispersed in the refrigerant scattering nozzle portion 16a can be uniformly sprayed on the entire coil connected to the waste heat source supply line 12. [

고온재생기(50) 내부에는 중간용액관(72)에 연결되는 중간용액산포노즐부(74)가 설치되어 저온재생기(70)에서 순환되는 흡수액이 중간용액관(72)에 연결되는 열교환기 전체에 고르게 분사되어 효과적인 열교환 작업을 행하게 된다.An intermediate solution scattering nozzle unit 74 connected to the intermediate solution pipe 72 is provided in the high temperature regenerator 50 and the absorption liquid circulated in the low temperature regenerator 70 is supplied to the entire heat exchanger connected to the intermediate solution pipe 72 So that an effective heat exchange operation is performed.

또한, 본 실시예의 보조용액관(82)은 보조희용액관(58)에 설치되는 보조열교환기(58a)를 통과하므로 보조흡수기(54)에서 배출되는 보조흡수액과, 보조재생기(80)에서 배출되는 보조흡수액이 보조열교환기(58a) 내부에서 열교환되면서 상대적으로 저온인 보조흡수기(54)의 보조흡수액에 의해 보조재생기(80)의 보조흡수액이 냉각되는 효과가 나타나게 된다.Since the auxiliary solution pipe 82 of the present embodiment passes through the auxiliary heat exchanger 58a provided in the auxiliary secondary solution pipe 58 and the auxiliary absorbent solution discharged from the auxiliary absorber 54 and the auxiliary absorbent solution discharged from the auxiliary regenerator 80 The auxiliary absorbent liquid of the auxiliary regenerator 80 is cooled by the auxiliary absorbent liquid of the auxiliary absorber 54 having a relatively low temperature while the auxiliary absorbent liquid is heat-exchanged inside the auxiliary heat exchanger 58a.

따라서 보조흡수기(54) 내부에서 냉각수와 열교환되어 냉각되는 보조흡수액이 보조재생기(80)에서 배출되는 냉매를 냉각시키게 되고, 보조재생기(80)에 설치되는 보조희용액산포노즐부(58b)에 의해 보조재생기(80) 내부에 설치되는 열교환기에 분사되면서 폐열원분기관(12a)을 따라 배출되는 폐열원을 냉각시키게 된다.Accordingly, the auxiliary absorption liquid, which is cooled by heat exchange with the cooling water in the auxiliary absorber 54, cools the refrigerant discharged from the auxiliary regenerator 80, and the auxiliary auxiliary solution spraying nozzle unit 58b installed in the auxiliary regenerator 80 The waste heat source that is discharged along the waste heat source orifice 12a while being sprayed to the heat exchanger installed in the auxiliary regenerator 80 is cooled.

상기한 바와 같이 폐열원분기관(12a)을 따라 배출되는 폐열원이 냉각수에 의해 냉각되는 냉매에 의해 보조재생기(80) 내부에서 열교환되므로 히트펌프로부터 배출되는 폐열원이 설정 온도 이상의 고온으로 배출되는 것을 방지할 수 있게 된다.As described above, the waste heat source discharged along the waste heat prime mover 12a is heat-exchanged in the auxiliary regenerator 80 by the refrigerant cooled by the cooling water, so that the waste heat source discharged from the heat pump is discharged at a temperature higher than the set temperature .
