흡수식 냉온수기 {ABSORPTION WATER COOLER AND HEATER}ABSORPTION WATER COOLER AND HEATER

본 발명은 흡수식 냉온수기에 관한 것으로서, 더욱 상세하게는 냉매증기를 재열기의 열원으로 활용하여 응축 효율을 향상시킬 수 있는 흡수식 냉온수기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an absorption type cold / hot water generating machine, and more particularly, to an absorption type cold water and water heater capable of improving condensation efficiency by utilizing a refrigerant vapor as a heat source for reheating.

일반적으로, 가스냉방은 전기 대신 가스를 열원으로 하여 냉방 및 난방을 구현하는 것으로, 이러한 가스냉방은 크게 흡수식 냉온수기 및 가스히터펌프로 구분된다.Generally, gas cooling is realized by cooling and heating by using gas as a heat source instead of electricity. Such gas cooling is roughly classified into an absorption type cold / hot water heater and a gas heater pump.

특히 흡수식 냉온수기는 친환경적이라는 장점이 있어, 건물의 냉난방시스템에 다양하게 적용되고 있다.Particularly, the absorption type cold / hot water heater has an advantage of being environment friendly, and is being applied variously to the heating / cooling system of a building.

이에 보조하여, 흡수식 냉온수기와 관련된 연구개발 등이 활발하게 진행되고 있다.In support of this, research and development related to the absorption type cold / hot water heater is actively proceeding.

종래의 흡수식 냉온수기는 도 1에 도시되어 있는 바와 같이, 고온재생기(1), 저온재생기(2), 응축기(3), 증발기(4), 흡수기(5), 저온열교환기(6) 및 고온열교환기(7)를 포함하여 구성된다. 이와 같은 구성에 의해 고온재생기(1) 내부의 흡수액은 고온열교환기(7)를 거쳐 저온재생기(2)로 유입되고, 이렇게 저온재생기(2)로 유입된 흡수액은 저온재생기(2)를 통과하는 고온재생기(1)의 증기에 의해 재가열되어 냉매증기가 생성된다. 그리고 저온재생기(2) 내부의 흡수액은 저온열교환기(6)를 거쳐 흡수기(5)로 유입되고, 냉매증기는 응축기(3)를 통과하면서 응축되어 증발기(4)로 유입된다. As shown in Fig. 1, the conventional absorption type cold and hot water heater includes a high temperature regenerator 1, a low temperature regenerator 2, a condenser 3, an evaporator 4, an absorber 5, a low temperature heat exchanger 6, (7). With this arrangement, the absorption liquid in the high-temperature regenerator 1 flows into the low-temperature regenerator 2 via the high-temperature heat exchanger 7, and the absorption liquid thus introduced into the low-temperature regenerator 2 passes through the low- Is reheated by the vapor of the high temperature regenerator (1) to generate the refrigerant vapor. The absorption liquid in the low temperature regenerator 2 flows into the absorber 5 through the low temperature heat exchanger 6 and the refrigerant vapor condenses while passing through the condenser 3 and flows into the evaporator 4.

위에서 설명한 흡수식 냉온수기는 등록특허공보 제10-1727431호에 개시되어 있다.The absorption-type cold / hot water heater described above is disclosed in Patent Registration No. 10-1727431.

그러나 위와 같은 흡수식 냉온수기는 저온재생기(2)에서 응축기(3)로 이동되는 냉매증기의 양이 많을 경우, 응축기(3)의 응축코일 전열면적 및 냉각수량이 커지게 되는 등 응축기(3)로 유입되는 냉매증기를 응축시키는 데 많은 경제적 비용이 소요된다.However, when the amount of the refrigerant vapor to be transferred from the low-temperature regenerator 2 to the condenser 3 is large, the absorption-type cold water heater of the above-mentioned absorption type causes the heat transfer area and the cooling water amount of the condenser coil 3 to become large, It takes a great deal of economic cost to condense the refrigerant vapor.

그리고 저온재생기(2)에서 생성된 냉매증기를 별도로 열원으로 활용하지 못하고 있는 실정이다.And the refrigerant vapor generated in the low temperature regenerator 2 can not be used as a heat source separately.

이는 결국, 흡수식 냉온수기의 기능성 및 사용성을 저하시키는 결과를 초래한다.This results in lowering the functionality and usability of the absorption chiller.

본 발명은 위와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명에서 해결하고자 하는 과제는 저온재생기에서 생성된 냉매증기를 별도의 열원으로 활용할 수 있음은 물론이고 응축 효율을 높일 수 있는 흡수식 냉온수기를 제공하고자 하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an absorption type cold / hot water heater capable of utilizing a refrigerant vapor generated in a low temperature regenerator as a separate heat source, I want to.

위와 같은 과제를 해결하기 위한 본 발명에 따른 흡수식 냉온수기는 고온재생기; 저온재생기; 응축기; 증발기; 흡수기; 저온열교환기; 고온열교환기; 저온재생기에서 생성된 냉매증기가 상기 응축기로 이동되는 증기유로 상에 위치하여, 상기 냉매증기에서 발생되는 열을 흡수하는 열흡수코일; 상기 열흡수코일의 하부에 위치하여, 상기 저온재생기에서 생성된 냉매증기 속에 포함된 흡수액 입자를 제거함과 아울러 상기 열흡수코일에서 낙하되는 응축수를 상기 응축기로 안내하는 엘리미네이터를 포함하는 것을 그 기술적 특징으로 한다.According to an aspect of the present invention, there is provided an absorption type cold water heater comprising: a high temperature regenerator; Low temperature regenerator; Condenser; evaporator; Absorber; Low temperature heat exchanger; High temperature heat exchanger; A heat absorbing coil for absorbing heat generated from the refrigerant vapor, the refrigerant vapor being generated in the low temperature regenerator, the heat absorbing coil being located on a vapor passage through which the refrigerant vapor is transferred to the condenser; And an eliminator which is located below the heat absorbing coil and removes absorbent particles contained in the refrigerant vapor generated in the low temperature regenerator and guides the condensed water dropped from the heat absorbing coil to the condenser, .

본 발명에 따른 흡수식 냉온수기는 열흡수코일을 통해 저온재생기에서 생성된 고온의 냉매증기를 별도의 열원으로 활용할 수 있으며, 또한 응축기의 냉각부하를 경감하여 응축코일의 전열면적 및 냉각수량을 줄임으로서 경제적 비용을 절감할 수 있다.The absorption-type cold water heater according to the present invention can utilize the high-temperature refrigerant vapor generated in the low-temperature regenerator through the heat absorbing coil as a separate heat source, and also reduces the cooling load of the condenser to reduce the heat transfer area and the cooling water quantity of the condenser coil, The cost can be reduced.

또한 엘리미네이터를 통해 열흡수코일로부터 낙하되는 응축수를 응축기의 내부로 간편하게 안내할 수 있다.Also, the condenser water falling from the heat absorbing coil can be easily guided to the inside of the condenser through the eliminator.

그로 인해, 흡수식 냉온수기의 기능성 및 사용성을 상대적으로 향상시킬 수 있다.Therefore, the functionality and usability of the absorption type cold and hot water generating machine can be relatively improved.

아래에서는 본 발명에 따른 흡수식 냉온수기를 첨부된 도면을 통해 상세히 설명한다.Hereinafter, an absorption type cold and hot water generating machine according to the present invention will be described in detail with reference to the accompanying drawings.

도 2 내지 도 4에 도시되어 있는 바와 같이, 본 발명에 따른 흡수식 냉온수기는 고온재생기(10); 저온재생기(20); 응축기(30); 증발기(40); 흡수기(50); 저온열교환기(60); 고온열교환기(70); 열흡수코일(80); 엘리미네이터(90)를 포함하여 구성된다.2 to 4, the absorption type cold and hot water generating machine according to the present invention includes a high temperature regenerator 10; A low temperature regenerator 20; A condenser 30; An evaporator 40; Absorber (50); A low temperature heat exchanger (60); A high temperature heat exchanger (70); A heat absorbing coil 80; And an eliminator (90).

이와 같은 구성의 흡수식 냉온수기는 전 사이클이 고진공 상태에서 이루어진다.In the absorption type cold / hot water generating machine of such a configuration, the entire cycle is performed in a high vacuum state.

고온재생기(10)는 그 내부에 흡수액이 충전되고, 이렇게 충전된 흡수액은 가스버너(B)를 통해 가열된다.The high-temperature regenerator 10 is filled with an absorbing liquid therein, and the thus-filled absorbing liquid is heated through the gas burner B.

이에 따라 고온재생기(10)의 내부에 수용되어 있는 흡수액의 온도가 약 140∼150℃ 정도로 상승하여 고온의 냉매증기가 생성되고, 남은 흡수액은 농도가 높아지게 된다.As a result, the temperature of the absorption liquid accommodated in the high temperature regenerator 10 is increased to about 140 to 150 DEG C to generate high temperature refrigerant vapor, and the concentration of the remaining absorption liquid becomes high.

한편, 고온재생기(10)에서 생성된 고온의 냉매증기는 저온재생기(20)를 통과하면서 열교환된 후 증발기(40)로 유입되고, 고온재생기(10)의 내부에 저장되어 있는 흡수액은 고온열교환기(70)를 통과하면서 열교환된 후 저온재생기(20)로 유입된다.On the other hand, the high-temperature refrigerant vapor generated in the high-temperature regenerator 10 is heat-exchanged while passing through the low-temperature regenerator 20, and then flows into the evaporator 40. The absorption liquid stored in the high- (70), and then flows into the low-temperature regenerator (20).

저온재생기(20)는 고온재생기(10)로부터 흡수액을 공급받아 재가열을 통해 냉매증기를 생성한다. The low temperature regenerator (20) receives the absorbing liquid from the high temperature regenerator (10) and generates the refrigerant vapor through reheating.

이때, 저온재생기(20)를 재가열하는 열원으로는 고온재생기(10)에서 발생되는 고온의 냉매증기가 사용된다.At this time, as a heat source for reheating the low temperature regenerator 20, high temperature refrigerant vapor generated in the high temperature regenerator 10 is used.

그리고 저온재생기(20)에서 생성된 냉매증기는 제1 보조엘리미네이터(90a)를 통과하여 응축기(30)의 내부로 유입되고, 저온재생기(20)의 내부에 저장되어 있는 흡수액은 저온열교환기(60)를 통과하면서 열교환된 후 흡수기(50)의 내부로 유입된다.The refrigerant vapor generated in the low temperature regenerator 20 flows into the interior of the condenser 30 through the first auxiliary eliminator 90a and the absorption liquid stored in the low temperature regenerator 20 passes through the low temperature heat exchanger Exchanged while passing through the absorber (60), and then flows into the absorber (50).

응축기(30)는 저온재생기(20)로부터 유입된 냉매증기를 응축시켜 응축수를 생성한다. The condenser 30 condenses the refrigerant vapor introduced from the low temperature regenerator 20 to generate condensed water.

이러한 응축기(30)의 내부에는 냉매증기를 응축시키기 위한 냉각수가 이동되는 응축코일이 일정 형태로 배치되고, 응축코일에 의해 생성된 응축수는 증발기(40)로 유입된다.Inside the condenser 30, a condensing coil for moving the cooling water for condensing the refrigerant vapor is arranged in a predetermined form, and the condensed water generated by the condensing coil flows into the evaporator 40.

한편, 저온재생기(20) 및 응축기(30)는 격벽(W)에 의해 그 공간이 서로 구분 형성되고, 도 3 및 도 4에 도시되어 있는 바와 같이 격벽(W)에는 적어도 하나의 응축수홀(H)이 구비된다. On the other hand, the low-temperature regenerator 20 and the condenser 30 are partitioned by the partition W to form at least one condensate hole H (see FIG. 3 and FIG. 4) .

이러한 응축수홀(H)은 저온재생기(20)에서 생성된 응축수를 응축기(30)로 유입시키기 위한 것이다.The condenser hole (H) is for introducing the condensed water generated in the low temperature regenerator (20) into the condenser (30).

증발기(40)는 고온재생기(10) 및 응축기(30)로부터 유입된 응축수를 증발시키기 위한 것으로, 그 내부에는 증발코일이 배치된다. 증발기(40)로 유입된 응축수(냉매)는 증발코일로 분사된다.The evaporator 40 is for evaporating the condensate introduced from the high temperature regenerator 10 and the condenser 30, and an evaporation coil is disposed therein. The condensed water (refrigerant) flowing into the evaporator 40 is injected into the evaporation coil.

그리고 증발기(40)에서 기화된 냉매증기는 제2 보조엘리미네이터(90b)를 통과하여 흡수기(50)로 유입된다.The vaporized refrigerant vapor in the evaporator 40 flows into the absorber 50 through the second auxiliary eliminator 90b.

흡수기(50)는 증발기(40)와 인접하게 설치되어, 증발기(40)에서 생성된 냉매증기가 흡수된다.The absorber 50 is installed adjacent to the evaporator 40 so that the refrigerant vapor generated in the evaporator 40 is absorbed.

그리고 흡수기(50)의 내부에는 흡수코일이 배치되며, 흡수코일은 응축기(30)의 응축코일과 연결된다. An absorption coil is disposed inside the absorber (50), and the absorption coil is connected to the condenser coil of the condenser (30).

한편, 저온재생기(20)로부터 유입된 흡수액은 내부의 흡수코일을 향하여 분사된다.On the other hand, the absorbing liquid introduced from the low temperature regenerator 20 is injected toward the inner absorbing coil.

저온열교환기(60) 및 고온열교환기(70)는 저온재생기(20)에서 흡수기(50)로 유입되는 흡수액을 열교환시키거나, 고온재생기(10)에서 저온재생기(20)로 유입되는 흡수액을 열교환시키거나, 흡수기(50)에서 고온재생기(10)로 유입되는 흡수액을 열교환시키는 역할을 한다.The low temperature heat exchanger 60 and the high temperature heat exchanger 70 heat exchange the absorbing liquid flowing into the absorber 50 from the low temperature regenerator 20 or heat exchange the absorbing liquid flowing into the low temperature regenerator 20 from the high temperature regenerator 10 Or plays a role of exchanging heat with the absorbing liquid flowing into the high temperature regenerator 10 from the absorber 50.

열흡수코일(80)은 저온재생기(20)에서 생성된 냉매증기에서 발생되는 열을 흡수하는 역할을 하며, 이러한 열흡수코일(80)을 통해 흡수된 열은 재열기 등의 열원으로 사용된다.The heat absorbing coil 80 absorbs heat generated in the refrigerant vapor generated in the low temperature regenerator 20 and the heat absorbed through the heat absorbing coil 80 is used as a heat source such as a reheater.

특히 열흡수코일(80)은 저온재생기(20)에서 생성된 냉매증기가 응축기(30)로 이동되는 증기유로 상에 위치하여, 저온재생기(20)에서 생성된 냉매증기가 응축기(30)로 이동하기 전에 1차적으로 열을 흡수하여 응축시킨다. 이에 따라, 응축기(30)에서 냉각수에 의해 응축되어야 할 냉매증기의 일부가 열흡수코일(80)에 의해 응축되므로 전체적인 냉각수량을 절감할 수 있을 뿐 아니라 응축코일의 전열면적도 줄일 수 있다.Particularly, the heat absorbing coil 80 is positioned so that the refrigerant vapor generated in the low temperature regenerator 20 is located on the vapor flow path where the refrigerant vapor is moved to the condenser 30 and the refrigerant vapor generated in the low temperature regenerator 20 is moved to the condenser 30 The heat is first absorbed and condensed before doing. Accordingly, since a part of the refrigerant vapor to be condensed by the cooling water in the condenser 30 is condensed by the heat absorption coil 80, not only the total cooling water amount can be reduced, but also the heat transfer area of the condensation coil can be reduced.

또한 동일 연소가스량에 의해 효율이 증대되어 COP(성적계수)가 증대되어 흡수식 냉온수기의 운전경비를 절감할 수 있다.In addition, the efficiency is increased by the same amount of combustion gas, so that the COP (coefficient of performance) is increased, and the operation cost of the absorption type cold / hot water heater can be reduced.

엘리미네이터(90)는 열흡수코일(80)의 하부에 위치하여, 저온재생기(20)에서 생성된 냉매증기 속에 포함된 흡수액 입자를 간편하고 효율적으로 제거함과 아울러 열흡수코일(80)에서 낙하되는 응축수를 응축기(30)의 내부로 안내하는 기능을 수행한다. 이러한 엘리미네이터(90)는 플레이트 형상으로 이루어져 지그재그로 배치되며, 그 최상단 부위의 일측 단부가 격벽(W)에 형성되어 있는 응축수홀(H)과 연통 설치된다.The eliminator 90 is positioned below the heat absorbing coil 80 to easily and efficiently remove the absorbing fluid particles contained in the refrigerant vapor generated in the low temperature regenerator 20, To the inside of the condenser (30). The eliminator 90 has a plate shape and is arranged in a staggered manner. One end of the upper end of the upper part is communicated with the condensed water hole H formed in the partition W.

엘리미네이터(90)의 최상단 부위는 열흡수코일(80)에서 낙하하는 응축수가 응축수홀(H)로 원활하게 흐르도록 일정 각도로 하향 경사지게 배치되는 것이 바람직하다.It is preferable that the uppermost part of the eliminator 90 is arranged to be inclined downward at a certain angle so that the condensed water falling from the heat absorbing coil 80 flows smoothly into the condensed water hole H. [

또한 도 5에 되시되어 있는 바와 같이, 엘리미네이터(90)의 최상단 부위 상면에는 열흡수코일(80)에서 낙하되는 응축수를 응축수홀(H)로 안내하는 홈 형상의 가이드유로(92)가 나란하게 다수 개 형성되어, 응축수의 흐름을 보다 원활하게 유지시킬 수 있다.5, a groove-shaped guide passage 92 for guiding the condensed water falling from the heat absorbing coil 80 to the condensed water hole H is formed on the upper surface of the uppermost portion of the eliminator 90 So that the flow of the condensed water can be maintained more smoothly.

한편, 엘리미네이터(90)가 없다면 냉매증기 속에 흡수액 입자가 포함되어 성능 저하가 발생되며, 열흡수코일(80)에서 발생된 응축수가 저온재생기(20) 내부에 저장되어 있는 흡수액으로 낙하되어 흡수액의 가열이 원활하게 이루어지지 않는다는 문제점이 있습니다. On the other hand, if there is no eliminator 90, the absorption liquid particles are contained in the refrigerant vapor and performance deterioration occurs. Condensate generated in the heat absorption coil 80 is dropped into the absorption liquid stored in the low temperature regenerator 20, There is a problem that the heating of the heater is not performed smoothly.

미설명 도면부호 P1은 흡수액을 이송시키기 위한 용액펌프이고, P2는 냉각탑으로 냉각수를 공급하기 위한 냉각수펌프이며, P3는 실내기로 냉온수를 공급하기 위한 냉온수순환펌프이다.P 2 is a cooling water pump for supplying cooling water to the cooling tower, and P 3 is a cold / hot water circulation pump for supplying cold / hot water to the indoor unit.

이상에서 설명한 흡수식 냉온수기의 작동과정을 간단하게 설명하면 다음과 같다.Hereinafter, the operation of the absorption type cold / hot water heater will be briefly described.

먼저, 고온재생기(10)에 흡수액을 채운 후 가스버너(B)를 이용하여 고온으로 가열하게 되면, 그 내부에서 고온의 냉매증기가 발생되고 남은 흡수액은 농도가 높아진다.First, when the high-temperature regenerator 10 is filled with the absorbing liquid and then heated to a high temperature by using the gas burner B, high-temperature refrigerant vapor is generated therein, and the concentration of the remaining absorbing liquid becomes high.

고온재생기(10)에서 생성된 냉매증기는 저온재생기(20)를 통과하면서 응축되어 증발기(40)로 유입되고, 저온재생기(20)에서 생성된 냉매증기는 응축기(30)를 통과하면서 응축되어 증발기(40)로 유입된다. 동시에 고온재생기(10)에서 가열된 흡수액은 고온열교환기(70)를 거치면서 열교환된 후 저온재생기(20)로 유입되고, 이렇게 저온재생기(20)로 유입된 흡수액은 고온재생기(10)에서 유입된 고온의 냉매증기에 의해서 다시 한 번 가열되어 농용액으로 된 상태로 저온열교환기(60)를 거쳐 흡수기(50)로 유입된다.The refrigerant vapor generated in the high temperature regenerator 10 is condensed while passing through the low temperature regenerator 20 and flows into the evaporator 40. The refrigerant vapor generated in the low temperature regenerator 20 is condensed while passing through the condenser 30, (40). At the same time, the absorbing liquid heated in the high temperature regenerator 10 is heat-exchanged through the high temperature heat exchanger 70 and then flows into the low temperature regenerator 20. The absorbing liquid thus introduced into the low temperature regenerator 20 is introduced into the high temperature regenerator 10 Heated by the high-temperature refrigerant vapor, and then flows into the absorber 50 through the low-temperature heat exchanger 60 in the form of a concentrated solution.

그리고 증발기(40)에서 기화된 냉매증기는 흡수기(50)로 유입된 농용액에 흡수되어 희용액이 되고, 이는 저온열교환기(60) 및 고온열교환기(70)를 거치면서 열교환되어 고온재생기(10)로 재유입된다.The refrigerant vaporized in the evaporator 40 is absorbed by the concentrated solution flowing into the absorber 50 and becomes a diluted solution which is heat exchanged while passing through the low temperature heat exchanger 60 and the high temperature heat exchanger 70, 10).
