일반적으로 리튬브로마이드 수용액(Lithium Bromide Solution)을 이용하여서 냉난방을 출력시키는 흡수식 냉난방기는 여러 가지 형태로 다양하게 제안되어있다.In general, various types of absorption air conditioners for outputting heating and cooling by using lithium bromide solution have been proposed in various forms.
그 일예로써는, 본 출원인에 의해서 대한민국에 1994년 1월 26일자로 실용 신안등록출원된 출원번호 94-1470호가 있다.An example of this is Application No. 94-1470 filed with a utility model registration on January 26, 1994 in the Republic of Korea by the present applicant.
종래의 실용신안등록출원 94-1470호에 의한 흡수식 냉난방기는, 제1도 및 제2도는 도시된 바와 같이 희용액을 가열하여 농용액과 냉매중기로 분리하는 발생기(1')와, 상기 발생기(1')에서 분리된 냉매증기를 냉매액으로 만드는 응축기(2')와, 상기 냉매액을 순환관외주연으로 흘려보내 증발시키는 열교환기(3')를 구비하는 흡수식 냉난방기에 있어서, 상기 열교환기(3')내주연으로 상기 농용액을 직접공급하여 상기 증발하는 냉매를 흡수하므로써 희용액으로 변환되도록 하는 것을 특징으로한다.Absorption type air conditioner according to the conventional utility model registration application 94-1470, 1 and 2 is a generator (1 ') for heating the rare solution to separate the concentrated solution and the refrigerant medium as shown in Figure 1, and the generator ( In an absorption type air conditioner and a heat exchanger having a condenser (2 ') for making the refrigerant vapor separated in 1') into a refrigerant liquid, and a heat exchanger (3 ') for flowing the refrigerant liquid to the outer periphery of the circulation tube, the heat exchanger ( 3 ') by directly supplying the agricultural solution to the inner circumference to absorb the evaporating refrigerant to be converted into a rare solution.
이와 같은 종래의 흡수식 냉난방기는 열교환기(3')의 내부로 냉매액과 농용액이 공급되고, 상기 열교환기(3')의 내부로 공급된 냉매액은 순환관으로 흘러 상기 순환관을 흐르는 물의 열을 뺏아 증발되어 냉매증기로 변환되며, 또 증발되어서 변환된 냉매증기가 농용액에 흡수되므로써 희용액으로 변환되었다.In the conventional absorption type air conditioner, the refrigerant liquid and the concentrated liquid are supplied into the heat exchanger 3 ', and the refrigerant liquid supplied into the heat exchanger 3' flows into the circulation tube to remove the water flowing through the circulation tube. The heat is evaporated and converted into refrigerant vapor, and the vaporized and converted refrigerant vapor is converted into a rare solution by being absorbed by the concentrated solution.
한편, 상기 발생기(1')를 통과해서 상기 열교환기(3')로 공급되는 농용액은 상기 열교환기(3')를 통과한 희용액과 용액열교환기(4')에서 열교환 되게 된다.Meanwhile, the concentrated solution supplied to the heat exchanger 3 'through the generator 1' is heat-exchanged in the solution heat exchanger 4 'and the rare solution passed through the heat exchanger 3'.
이때, 상기 용액열교환기(4')를 통과한 농용액의 온도는 대체로 제2도에 도시한 H'점이 되고, 상기 용액열교환기(4')에서 열교환된후 상기 열교환기(3')로 공급되는 농용액의 온도는 제2도에 도시한 A' 점이 되게 된다.At this time, the temperature of the concentrated solution passing through the solution heat exchanger (4 ') becomes a point H' generally shown in FIG. 2, heat exchanged in the solution heat exchanger (4 ') and then to the heat exchanger (3'). The temperature of the supplied agricultural solution becomes A 'point shown in FIG.
즉, 상기 열교환기(3')로 공급되는 농용액의 온도는 용액의 결정석출라인(L)에 근접한 온도가 된다.That is, the temperature of the concentrated solution supplied to the heat exchanger 3 'becomes a temperature close to the crystallization line (L) of the solution.
또, 상기 열교환기(3')로 공급되는 농용액의 온도가 용액의 결정석출라인(L)에 근접한 비교적 높은 온도로 유지되므로써, 농용액의 압력도 상승되며(PV=nRT에 의해서 온도가 상승되면 압력도 상승되게된다), 농용액의 압력이 상승됨에 따라서 농용액에 혼합된 물의 분압도 상승되며, 이 농용액에 혼합된 물의 분압의 상승으로 인해 냉매증기가 보다 원활하게 농용액에 흡수되지 못하게된다.In addition, since the temperature of the agricultural liquid supplied to the heat exchanger 3 'is maintained at a relatively high temperature close to the crystallization line L of the liquid, the pressure of the agricultural liquid is also increased (the temperature is increased by PV = nRT). Pressure increases, and as the pressure of the agricultural liquid increases, the partial pressure of the water mixed into the agricultural liquid also increases, and the refrigerant vapor is not absorbed into the agricultural liquid more smoothly due to the increase of the partial pressure of the water mixed into the agricultural liquid. Will not.
즉, 상기 열교환기(3')로 비교적 높은 온도의 농용액이 공급되므로써 냉매증기가 원활하게 흡수되지 못해 흡수효율이 저하되어 냉난방 효울이 저하됨과 동시에 농용액의 결정석출현상이 발생되어 제품의 신뢰도를 저하시킨다는 등의 여러 가지 문제점들이 있었다.In other words, the relatively high temperature of the agricultural solution is supplied to the heat exchanger (3 '), the refrigerant vapor is not absorbed smoothly, the absorption efficiency is lowered, the cooling and heating effect is lowered, and the crystal precipitation phenomenon of the agricultural solution is generated, the reliability of the product There were various problems such as lowering.
본 고안은 상술한 여러 가지 문제점들을 감안해서 이루어진 것으로써, 본 고안의 목적은 열교환기(이하, '흡수증발기'라 한다)로 공급되는 농용액을 예냉시켜 보다 많은 냉매증기가 원활하게 농용액에 흡수되도록하여 흡수 효율을 보다 향상시킴과 동시에 농용액의 결정석출현상을 방지하여 제품의 신뢰도를 보다 향상시킬 수 있는 흡수식 냉난방기를 제공하는데있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to pre-cool the agricultural liquid supplied to a heat exchanger (hereinafter, referred to as an 'absorption evaporator') to allow more refrigerant vapor to smoothly flow into the agricultural liquid.

It can improve the reliability.
이하, 본 고안에 의한 흡수식 냉난방기의 일실시예를 첨부 도면을 첨조하여 상세하게 설명한다.Hereinafter, an embodiment of an absorption type air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 적용되는 흡수식 냉난방기의 구성을 개략적으로 도시한 구성도이고, 제4도는 본 고안에 적용되는 흡수식 냉난방기의 온도 변화를 도시한 듀링선도이다.3 is a configuration diagram schematically showing the configuration of the absorption type air conditioner applied to the present invention, Figure 4 is a During diagram showing the temperature change of the absorption type air conditioner applied to the present invention.
제3도 및 제4도에 있어서, (10)은 발생기로써, 후술하는 흡수증발기를 통과한 희용액을 도시되지 않은 버너 등의 열발생수단으로 부터 발생되는 열에 의해서 농용액과 냉매증기로 분리시킨다.In FIG. 3 and FIG. 4, reference numeral 10 denotes a generator, in which a rare solution passed through an absorption evaporator described later is separated into a concentrated solution and a refrigerant vapor by heat generated from a heat generating means such as a burner (not shown). .
이때, 상기 발생기(10)를 통과하는 농용액과 냉매증기의 온도는 제4도에 도시한 듀링선도에서 E점이 된다.At this time, the temperature of the concentrated solution and the refrigerant vapor passing through the generator 10 is point E in the During diagram shown in FIG.
또, (12)는 상기 발생기(10)에서 분리된 냉매증기를 응축시켜 냉매액으로 변환시키는 응축기이고, (20)은 상기 응축기(12)에서 응축된 냉매액을 증발작용시킴과 동시에 냉매증기가 농용액에 흡수되어 희용액으로 변환시키는 흡수증발기이다.In addition, (12) is a condenser that condenses the refrigerant vapor separated in the generator 10 to convert it into a refrigerant liquid, and (20) evaporates the refrigerant liquid condensed in the condenser 12 and at the same time the refrigerant vapor Absorption evaporator which is absorbed by a concentrated solution and converted into a rare solution.
이때, 상기 응축기(12)의 입구로 공급되는 냉매증기의 온도는 듀링선도에서 C점이 되고, 상기 응축기(12)를 통과하여 상기 흡수증발기(20)로 공급되는 냉매액의 온도는 D점이 된다.At this time, the temperature of the refrigerant vapor supplied to the inlet of the condenser 12 becomes point C in the During diagram, and the temperature of the refrigerant liquid supplied to the absorption evaporator 20 through the condenser 12 becomes D point.
또, 상기 응축기(12)는 보다 많은 양의 냉매증기를 응축시킬 수 있도록 다수개가 조합되어 형성되며, 상기 응축기(12)에는 보다 용이하게 냉매 증기가 응축되도록 공냉핀(121)이 배설되어 있다.In addition, the condenser 12 is formed by combining a plurality of the condenser 12 to condense a larger amount of refrigerant vapor, the air condenser 12 is provided with an air cooling fin 121 to more easily condensate the refrigerant vapor.
또한, 상기 흡수증발기(20)의 상부에는 상기 응축기(12)에서 응축된 냉매액을 분배하는 냉매액분배기(21) 및 상기 발생기(10)에서 분리된 농용액을 분배하는 용액분배기(22)가 배설되고, 내부에는 파이프부재(23)가 배설되어있다.In addition, the upper portion of the absorption evaporator 20 is a refrigerant liquid distributor 21 for distributing the refrigerant liquid condensed in the condenser 12 and a solution distributor 22 for distributing the concentrated liquid separated from the generator 10 Exposed and the pipe member 23 is arrange | positioned inside.
또, 상기 흡수증발기(20)와 상기 발생기(10)와의 사이에는 상기 발생기(10)에서 분리된 농용액과 상기 흡수증발기(20)에서 생성된 희용액의 열을 열교환시키는 용액열교환기(16)가 배설된다.In addition, between the absorption evaporator 20 and the generator 10, a solution heat exchanger 16 for heat-exchanging the heat of the concentrated solution separated from the generator 10 and the rare solution generated by the absorption evaporator 20. Is excreted.
또한, 상기 흡수증발기(20)와 상기 발생기(10)의 사이에는 상기 용액열교환기(16)에서 열교환된 농용액을 예냉시키는 예냉수단(80)이 배설된다.In addition, between the absorption evaporator 20 and the generator 10 is provided with pre-cooling means 80 for pre-cooling the concentrated solution heat exchanged in the solution heat exchanger (16).
즉, 상기 예냉수단(80)은, 상기 발생기(10)에서 분리되고 상기 용액 열교환기(16)에서 열교환된 농용액의 흐름을 가이드하는 가이드관(81)과, 상기 가이드관(81)으로 흐르는 농용액을 예냉시키는 공냉핀(82)으로 이루어져, 상기 용액열교환기(16)를 통과한 농용액을 예냉시켜 제4도에 도시한 듀링선도의 A점으로 농용액의 온도를 저히시킨다.That is, the precooling means 80, the guide tube 81 for guiding the flow of the agricultural solution separated from the generator 10 and heat-exchanged in the solution heat exchanger 16, and flows to the guide tube 81 It consists of an air cooling fin 82 for precooling the concentrated solution, and precooled the concentrated solution passed through the solution heat exchanger 16 to lower the temperature of the concentrated solution to point A in the During diagram shown in FIG.
이때, 상기 예냉수단(80)을 통해서 상기 용액분배기(22)로 분배되는 농용액은 결정석출라인(L)으로부터 멀어진 낮은 온도 상태이므로 보다 많은 냉매증기를 흡수시킬 수 있음과 동시에 농용액의 결정석출현상을 방지할 수 있는 것이다.At this time, the concentrated solution distributed to the solution distributor 22 through the pre-cooling means 80 is a low temperature state away from the crystal precipitation line (L) can absorb more refrigerant vapor and at the same time crystallization of the concentrated solution The phenomenon can be prevented.
한편, 상기 흡수증발기(20)의 외주에는 상기 용액분배기(22)를 통해 공급된 농용액이 원활하게 흘러내리도록 연속된 와이어부재(24)가 감겨져있고, 상기 파이프부재(23)의 외측방향에는 상기 와이어부재(24)를 타고 흘러 내리는 농용액이 상기 파이프부재(23)방향으로 튀지않도록 엘리미네이터수단(30)이 배설되어 있다.On the other hand, a continuous wire member 24 is wound around the outer periphery of the absorption evaporator 20 so that the agricultural solution supplied through the solution distributor 22 flows smoothly, and in the outer direction of the pipe member 23. The eliminator means 30 is disposed so that the concentrated solution flowing down the wire member 24 does not splash in the direction of the pipe member 23.
즉, 상기 흡수증발기(20)에 엘리미네이터수단(30)이 배설되므로써 상기 와이어부재(23)에 가이드 되어서 흘러내리는 농용액이 상기 파이프부재(23)방향으로 튀는 것이 방지되며, 이로 인해 상기 냉매액분배기(21)를 통해서 공급된 냉매액이 상기 파이프부재(23)의 내부로 흐르는 물 등의 열을 보다 용이하게 뺏아 증발되어 냉매증기로 별환된다.That is, since the eliminator means 30 is disposed in the absorption evaporator 20, the agricultural solution guided to the wire member 23 and flowed down is prevented from splashing in the direction of the pipe member 23. The coolant liquid supplied through the liquid distributor 21 is more easily desorbed by heat such as water flowing into the pipe member 23 and evaporated to be converted back into the refrigerant vapor.
또, 상기 흡수증발기(20)의 하부에는, 냉매증기가 농용액에 흡수되어 변환된 희용액과 증발되지 못한 냉매액이 혼합되지 않도록 희용액과 냉매액을 분리시키는 분리수단(40)이 배설되어 있다.In addition, the lower portion of the absorption evaporator 20, the separation means 40 for separating the rare solution and the refrigerant liquid is disposed so that the refrigerant vapor is not absorbed by the concentrated solution and the refrigerant solution is not evaporated mixed with the refrigerant vapor is disposed have.
또한, 상기 흡수증발기(20)에는 상기 분리수단(40)에 의해서 분리된 냉매액이 상기 발생기(10)로 공급됨이 없이 상기 냉매액분배기(22)를 통해 상기 흡수증발기(20)로 재공급되도록 재공급수단(50)이 장착되어 있다.In addition, the refrigerant evaporator 20 is resupplied to the absorption evaporator 20 through the refrigerant liquid distributor 22 without supplying the refrigerant liquid separated by the separating means 40 to the generator 10. The resupply means 50 is mounted as possible.
즉, 상기 재공급수단(50)은 일단이 상기 흡수증발기(20)의 하부에 접속되고 타단이 상기 냉매액분배기(22)에 접속되어서 증발되지 못한 냉매액의 흐름을 가이드하는 가이드부재(52)와, 상기 가이드부재(52)에 가이드도되는 냉매액이 상기 용액분배기(22)로 공급되도록 동력을 발생시키는 펌프(51)로 이루어져서, 증발되지 못한 냉매액을 상기 냉매액분배기(21)로 재공급하는 것이다.한편, 그림에서 (15)는 상기 흡수증발기(20)에서 변환된 희용액이 상기 발생기(10)로 공급되도록 동력을 발생시키는 펌프부재이고, (15')는 상기 발생기(10)에서 분리된 농용액을 상기 흡수증발기(20)로 공급하는 펌프부재이며, (15'')는 상기 응축기(12)에서 응축된 냉매액을 상기 흡수증발기(20)로 공급하는 펌프부재이다.That is, the resupply means 50 is one end is connected to the lower portion of the absorption evaporator 20 and the other end is connected to the refrigerant liquid distributor 22, the guide member 52 for guiding the flow of the refrigerant liquid that did not evaporate And a pump 51 which generates power so that the coolant liquid guided to the guide member 52 is supplied to the solution distributor 22, so that the coolant liquid that has not evaporated is re-transmitted to the coolant liquid distributor 21. In the figure, reference numeral 15 denotes a pump member that generates power to supply the rare solution converted in the absorption evaporator 20 to the generator 10, and 15 'denotes the generator 10. The pump member for supplying the concentrated solution separated in the absorption evaporator 20, (15 '') is a pump member for supplying the refrigerant liquid condensed in the condenser 12 to the absorption evaporator (20).
다음은, 상기와 같이 구성된 본 고안에 의한 흡수식 냉난방기의 작용효과를 설명한다.Next, the effect of the absorption type air conditioner according to the present invention configured as described above will be described.
상기 발생기(10)에 도시되지 않은 버너 등의 열발생수단으로부터 발생되는 열이 가하지면 상기 발생기(10)의 희용액이 열원에 의해서 냉매증기와 농용액으된다.When heat generated from a heat generating means such as a burner (not shown) is applied to the generator 10, the rare solution of the generator 10 becomes a refrigerant vapor and a concentrated solution by a heat source.
이때, 상기 발생기(10)의 농용액과 냉매증기의 온도는 듀링 선도의 E점이 된다.At this time, the temperature of the concentrated solution and the refrigerant vapor of the generator 10 is point E of the During diagram.
또, 상기 발생기(10)에서 분리된 냉매증기는 상기 응축기(12)로 공급되고, 상기 발생기(10)에서 분리된 농용액은 상기 용액열교환기(16)를 거쳐 상기 예냉수단(80)으로 공급된다.In addition, the refrigerant vapor separated from the generator (10) is supplied to the condenser (12), and the concentrated solution separated from the generator (10) is supplied to the precooling means (80) via the solution heat exchanger (16). do.
이때, 상기 응축기(12)로 공급되는 냉매증기의 온도는 듀링선도의 C점이되고, 상기 응축기(12)에서 응축되어 상기 냉매액분배기(21)에 의해 분배되는 냉매액의 온도는 듀링선도에서 D점이 된다.At this time, the temperature of the refrigerant vapor supplied to the condenser 12 is point C of the During diagram, the temperature of the refrigerant liquid condensed in the condenser 12 and distributed by the refrigerant liquid distributor 21 is D in the During diagram. It becomes a point.
한편, 상기 발생기(10)에서 분리되어 상기 용액열교환기(16)로 통과하는 농용액은 상기 흡수증발기(20)에서 생성된 희용액과 열교환되어 듀링선도의 H점으로 온도가 저하되고, 상기 용액열교환기(16)를 통과한 농용액은 상기 예냉수단(80)을 거치므로써 농용액의 온도가 듀링선도의 A점으로 급격하게 저하된다.Meanwhile, the concentrated solution separated from the generator 10 and passed through the solution heat exchanger 16 is heat-exchanged with the rare solution generated in the absorption evaporator 20 to lower the temperature to the H point of the During diagram, and the solution As the concentrated solution passed through the heat exchanger 16 passes through the precooling means 80, the temperature of the concentrated solution rapidly drops to the point A of the During diagram.
즉, 상기 발생기(10)에서 분리된 농용액은 상기 용액열교환기(16)와 상기 예냉수단(80)을 통과하므로써 농용액의 온도가 듀링선도의 A점으로 저하되어 상기 용액분배기(22)에 의해 분배되어 상기 흡수증발기(20)로 공급된다.That is, the concentrated solution separated by the generator 10 passes through the solution heat exchanger 16 and the precooling means 80, so that the temperature of the concentrated solution is lowered to the point A of the During diagram, so that the solution distributor 22 Is distributed to the absorption evaporator 20.
이때, 상기 용액분배기(22)에 의해 분배되는 농용액의 온도는 결정석출라인(L)으로 부터 멀어진 저온이고, 이 농용액의 온도저하로 농용액에 함유된 물의 분압이 저하되며, 물의 분압 저하로 농용액은 보다 많이 냉매증기를 흡수할 수 있다.At this time, the temperature of the agricultural solution distributed by the solution distributor 22 is a low temperature away from the crystallization precipitation line (L), the partial pressure of the water contained in the agricultural solution is lowered by the temperature decrease of the agricultural solution, the partial pressure of the water is lowered As a result, the concentrated solution can absorb more refrigerant vapor.
또한, 상기 용액분배기(22)를 통해서 공급되는 농용액은 상기 흡수증발기(20)에 연속적으로 감겨진 상기 와이어부재(24)에 가이드되어 원활하게 흐르게 되며, 상기 와이어부재(24)에 가이드 되어서 흐르는 농용액은 상기 엘리미네이터수단(30)에 의해 상기 파이프부재(23)로 튈 우려가 발생되지 않게 된다.In addition, the concentrated solution supplied through the solution distributor 22 is guided to the wire member 24 continuously wound on the absorption evaporator 20 to flow smoothly, guided to the wire member 24 Concentration of the concentrated solution to the pipe member 23 by the eliminator means 30 is not generated.
한편, 상기 흡수증발기(20)에 배설된 상기 파이프부재(23)의 내부에는 물등이 흐르며, 상기 파이프부재(23)의 내부로 흐르는 물은 상기 냉매액 분배기(21)로부터 공급된 냉매액으로 열을 빼았겨 차가운 물로 되어 냉방 출력을 발생 시킨다.Meanwhile, water and the like flow inside the pipe member 23 disposed in the absorption evaporator 20, and water flowing into the pipe member 23 is heated by the refrigerant liquid supplied from the refrigerant liquid distributor 21. After subtracting, it becomes cold water and generates cooling output.
또, 열을 빼앗은 냉매액은 증발작용되어서 냉매증기로 변환되고, 이 변환된 냉매증기는 상기 용액분배기(22)를 통해서 공급되는 농용액에 흡수되어 희용액으로 변환된다.In addition, the refrigerant liquid deprived of heat is evaporated to be converted into refrigerant vapor, and the converted refrigerant vapor is absorbed by the concentrated solution supplied through the solution distributor 22 and converted into a rare solution.
이때, 증발되어 변환된 냉매증기는, 상기 예냉수단(80) 등에 의해 예냉되어 온도가 저하된 농용액에 흡수되므로써 보다 많은 양이 흡수된다.At this time, the refrigerant vapor, which has been evaporated and converted, is absorbed in the concentrated solution which is precooled by the precooling means 80 or the like and the temperature is lowered, thereby absorbing a larger amount.
이로 인해서, 흡수효율이 향상되어 보다 효율이 향상된 냉난방 출력을 출력시킬 수 있는 것이다.As a result, the absorption efficiency is improved, and thus the cooling and heating output with improved efficiency can be output.
한편, 상기 냉매액분배기(21)를 통해 공급되어 증발되지 못한 냉매액과, 증발된 냉매증기가 농용액에 흡수되어 변환된 희용액은 상기 흡수증발기(20)에 배설된 분리수단(40)에 의해 혼합되지 못하게 된다.On the other hand, the refrigerant liquid which is supplied through the refrigerant liquid distributor 21 and cannot be evaporated, and the rare liquid which is converted and absorbed by the evaporated refrigerant vapor into the agricultural solution are separated into the separation means 40 disposed in the absorption evaporator 20. To prevent mixing.
즉, 상기 흡수증발기(20)에 배설된 분리수단(40)에 의해서 희용액과 냉매액은 혼합됨이 없이 분리되게 되는 것이다.That is, the rare solution and the refrigerant liquid are separated without being mixed by the separating means 40 disposed in the absorption evaporator 20.
또, 상기 분리수단(40)에 의해 분리된 냉매액은 상기 발생기(10)로 공급됨이 없이 상기제공급수단(50)에 의해 상기 냉매액분배기(23)로 공급되어서 증발 작용되어 냉매증기로 변환되므로써 상기 용액분배기(22)를 통해 공급되는 농용액에 흡수된다.In addition, the refrigerant liquid separated by the separating means 40 is supplied to the refrigerant liquid distributor 23 by the agent supply means 50 without being supplied to the generator 10, and is evaporated to provide refrigerant refrigerant. The conversion is absorbed by the concentrated solution supplied through the solution distributor 22.
또한, 상기 분리수단(40)에 의해서 분리된 희용액은 상기 열교환기(16)를 거쳐 상기 발생기(10)로 공급되어 도시되지 않은 버너수단의 열원에 의해 가열되어 농용액과 냉매증기로 분리되게 된다.In addition, the rare solution separated by the separating means 40 is supplied to the generator 10 via the heat exchanger 16 and heated by a heat source of a burner means (not shown) to be separated into a concentrated solution and a refrigerant vapor. do.
이때, 상기 발생기(10)로는 상기 흡수증발기(20)에서 증발되지 못한 냉매액이 공급되지 않으므로써 불필요한 열원이 소요되지 않게되며, 이로인해 흡수식 냉난방기의 냉난방 효율을 보다 향상시킬 수 있는 것이다.At this time, the generator 10 is not supplied with the refrigerant liquid that has not been evaporated from the absorption evaporator 20 so that unnecessary heat source is not required, thereby improving the heating and cooling efficiency of the absorption type air conditioner.
앞에서 설명한 바와같이, 본 고안에 의한 리튬브로마이드수용액을 이용한 흡수식 냉나방기에 의하면, 흡수증발기로 공급되는 농용액을 저온으로 예냉시키므로써 흡수효율을 향상시켜 냉난방 효율을 향상시킬수 있음과 동시에 농용액의 결정석출현상을 방지하여 제품의 신뢰도를 향상 시킬 수 있다는 매우 실용적인 효과가 있는 것이다.As described above, according to the absorption type air conditioner using the lithium bromide aqueous solution according to the present invention, by pre-cooling the agricultural liquid supplied to the absorption evaporator at low temperature, the absorption efficiency can be improved to improve the cooling and heating efficiency, and at the same time, the determination of the agricultural liquid. There is a very practical effect that can prevent the precipitation phenomenon to improve the reliability of the product.
