The second bypass pipe 62 is connected to the main pipe 60 to allow the refrigerant discharged from the heat generator 100 to flow into the accumulator 27. In this case, the point where the 2nd bypass pipe 62 is connected with the main pipe 60 is located downstream from the 1st bypass pipe 61.

도 2a는 열발생장치의 단면도이다. 도 2a를 참조하면, 열발생장치(100)는 냉매와의 물리 흡착에 의해 열을 발생하는 흡착제(120)와, 상기 흡착제(120)가 충진된 탱크(110)와, 흡착제(120)를 재생하기 위해 흡착제(120)에 열을 전달하는 전열관(130)으로 구성된다.2A is a cross-sectional view of the heat generating device. Referring to FIG. 2A, the heat generator 100 regenerates an adsorbent 120 that generates heat by physical adsorption with a refrigerant, a tank 110 filled with the adsorbent 120, and an adsorbent 120. In order to transfer the heat to the adsorbent 120 is composed of a heat pipe (130).
본 발명의 일 실시예에 따른 열발생장치(100)는 냉매를 가열하기 위해 냉매가 흡착제(120)와 접촉하여 부착(adhere)되는 물리 흡착(physical adsorption)을 이용한 것이다. 물리 흡착은 항상 발열 반응이며, 물리 흡착에 의해 발생하는 열을 이용하여 냉매를 가열할 수 있다. 열발생장치(100)는 흡착제(120)에 냉매를 흡착시키고 발생하는 흡착열로 냉매를 가열하여 고온의 냉매를 토출시킬 수 있다.The heat generating apparatus 100 according to an embodiment of the present invention uses physical adsorption in which the refrigerant is contacted with and adsorbed to the adsorbent 120 to heat the refrigerant. Physical adsorption is always an exothermic reaction, and the refrigerant can be heated using heat generated by physical adsorption. The heat generator 100 may adsorb the refrigerant to the adsorbent 120 and heat the refrigerant with the generated adsorption heat to discharge the high temperature refrigerant.
흡착제(120)는 실리카계 또는 제올라이트계와 같은 고체흡착제가 주로 사용될 수 있다. 예를 들면, 흡착제(120)는 활성탄, 메로폴라스 실리카, 제올라이트, 실리카 겔, 점토 광물 등이 될 수 있다. 흡착(adsorption)은 흡착제(120)의 계면(solid interface) 어느 곳에서 일어나므로, 흡착제(120)의 계면을 증가시키기 위해 흡착제(120)는 다공성(porous)이다.The adsorbent 120 may mainly be a solid adsorbent such as silica or zeolite. For example, the adsorbent 120 may be activated carbon, meropolar silica, zeolite, silica gel, clay mineral, or the like. Adsorption occurs at a solid interface of the adsorbent 120, so that the adsorbent 120 is porous to increase the interface of the adsorbent 120.
탱크(110) 내부에 흡착제(120)가 충진되고, 탱크(110)의 일측에는 냉매가 유입되는 유입구(111)와 흡착열에 의해 가열된 고온의 냉매가 배출되는 배출구(113)가 형성된다. 유입구(111)를 통해 열발생장치(100)로 유입된 냉매는 압력차에 의해 배출구(113)로 배출되며, 유입구(111) 및 배출구(113)는 각각 유입바이패스관(63) 및 배출바이패스관(65)상호 연통되게 연결되어 있다. 유입바이패스관(63)에 흐르는 냉매는 유입구(111)를 통해 탱크(110) 내의 흡착제(120)와 직접 접촉하여 물리 흡착하고, 물리 흡착에 의해 발생한 흡착열에 의해 탱크(110)에 유입된 냉매를 가열하고, 가열된 냉매는 배출구(113)를 통해 배출바이패스관(65)으로 배출된다. The adsorbent 120 is filled in the tank 110, and one side of the tank 110 is formed with an inlet 111 through which the refrigerant is introduced and an outlet 113 through which a high temperature refrigerant heated by adsorption heat is discharged. The refrigerant introduced into the heat generating device 100 through the inlet 111 is discharged to the outlet 113 by the pressure difference, and the inlet 111 and the outlet 113 are inlet bypass pipe 63 and outlet bypass, respectively. The pass pipe 65 is connected in mutual communication. The refrigerant flowing in the inlet bypass pipe 63 is in direct contact with the adsorbent 120 in the tank 110 through the inlet 111 and is physically adsorbed, and the refrigerant is introduced into the tank 110 by the adsorption heat generated by the physical adsorption. Is heated, and the heated refrigerant is discharged to the discharge bypass pipe 65 through the discharge port 113.
종래에는 필요한 열량을 축적하기 위해 축열재의 양을 늘려 축열조의 크기가 커지는 문제가 있었으나, 본 발명의 일 실시예에 따른 열발생장치(100)는 냉매와 발열 반응하는 흡착제(120)를 사용하기 때문에 컴팩트한 열발생장치(100)를 제공할 수 있어 크기가 작은 실외기를 제공할 수 있고, 열발생장치(100)와 종래의 축열조가 동일한 크기라면 더 높은 효율을 갖는 보조 열원을 제공할 수 있는 이점이 있다. Conventionally, there was a problem that the size of the heat storage tank is increased by increasing the amount of heat storage material in order to accumulate necessary heat amount, but the heat generating device 100 according to an embodiment of the present invention uses the adsorbent 120 to exothermicly react with the refrigerant. The compact heat generator 100 can be provided to provide an outdoor unit having a small size, and if the heat generator 100 and the conventional heat storage tank are the same size, an auxiliary heat source having higher efficiency can be provided. There is this.
제상 운전 시, 공기조화기(1)는 압축기(21)로부터 압축된 냉매가 실외 열교환기(23)로 유동되도록 하여 실외 열교환기(23)의 제상이 실시되도록 한다. 압축기(21)에서 압축된 냉매는 사방밸브(25)를 경유하여 실외 열교환기(23)로 유입되어 제상 작용을 수행한다. In the defrosting operation, the air conditioner 1 allows the refrigerant compressed from the compressor 21 to flow to the outdoor heat exchanger 23 so that the outdoor heat exchanger 23 may be defrosted. The refrigerant compressed by the compressor 21 flows into the outdoor heat exchanger 23 via the four-way valve 25 to perform defrosting.
이 경우, 실내기(10)로부터 유입측 냉매관(51)을 통해 유입된 냉매를 열발생장치(100)로 유동되도록하여 열발생장치(100)를 통해 냉매를 가열시켜 압축기로부터 공급되는 열량을 낮출 수 있어 효율적인 제상이 실시될 수 있다. In this case, the refrigerant introduced from the indoor unit 10 through the inlet refrigerant pipe 51 flows to the heat generating device 100 to heat the refrigerant through the heat generating device 100 to lower the amount of heat supplied from the compressor. It can be carried out efficient defrosting.
유입측 냉매관(51)을 통해 유입되어 어큐뮬레이터(27)로 흡입되는 냉매를 바이패스관(61)으로 유동되도록 한다. 유입바이패스관(63)으로 유입된 냉매의 일부는 열발생장치(100)에서 흡착제(120)와 물리 흡착하고, 나머지 냉매는 흡착열에 의해 가열되어 배출바이패스관(65)으로 배출된다. 열발생장치(100)에서 배출된 고온의 냉매는 어큐뮬레이터(27)를 경유하여 압축기(21)로 흡입되고, 압축되어 토출되어 실외 열교환기(23)에서 제상작용을 수행한다. 본 발명의 일실시예에 따른 열발생장치(100)가 제상 운전 시 보조 열원의 기능을 하여 제상 성능이 높아지고, 빠른 난방 복귀가 가능하다. 또한, 압축기(21)로부터 공급되는 열량을 낮아져 공기조화기(1)의 에너지 절감 효과를 얻을 수 있다.The refrigerant introduced through the inlet refrigerant pipe 51 and sucked into the accumulator 27 is allowed to flow into the bypass pipe 61. Some of the refrigerant introduced into the inlet bypass pipe 63 is physically adsorbed with the adsorbent 120 in the heat generating device 100, and the remaining refrigerant is heated by the adsorption heat and discharged into the discharge bypass pipe 65. The high temperature refrigerant discharged from the heat generator 100 is sucked into the compressor 21 via the accumulator 27, compressed and discharged to perform defrosting in the outdoor heat exchanger 23. The heat generating device 100 according to an embodiment of the present invention functions as an auxiliary heat source during defrosting operation, thereby increasing defrosting performance and enabling rapid heating return. In addition, the amount of heat supplied from the compressor 21 is lowered to obtain the energy saving effect of the air conditioner 1.
흡착제의 재생(regeneration)은 흡착제(120)에 흡착된 냉매를 흡착제(120) 표면로부터 제거하는 것을 말한다. 흡착의 역반응으로 흡착된 냉매가 흡착제(120)의 표면에서 떨어져 나가는 현상을 탈착이라고 하는데, 재생과정에서 탈착하는 과정이 포함된다. 탈착은 흡착제(120) 표면의 온도가 높아지면 나타난다. 흡착제(120)에 열을 가하면 흡착된 냉매가 흡착제(120) 표면으로부터 분리되어 흡착제(120)는 다시 물리 흡착할 수 있도록 재생된다.Regeneration of the adsorbent refers to removing the refrigerant adsorbed to the adsorbent 120 from the surface of the adsorbent 120. Desorption of the adsorbed refrigerant off the surface of the adsorbent 120 due to the reverse reaction of adsorption is called desorption, which includes a process of desorption in the regeneration process. Desorption occurs when the temperature of the surface of the adsorbent 120 increases. When heat is applied to the adsorbent 120, the adsorbed refrigerant is separated from the surface of the adsorbent 120, and the adsorbent 120 is regenerated to be physically adsorbed again.
전열관(130)은 흡착제(120)의 재생을 위한 것으로, 흡착제(120)와 직접 접촉하도록 탱크(110)의 내부를 관통하도록 형성될 수 있다. 전열관(130)은 전열관(130)의 내부에 흐르는 오일 또는 냉매가 갖는 열을 흡착제(120)로 전달할 수 있도록 전도성 물질로 형성될 수 있다. The heat transfer tube 130 is for regeneration of the adsorbent 120 and may be formed to penetrate the inside of the tank 110 to be in direct contact with the adsorbent 120. The heat transfer tube 130 may be formed of a conductive material so as to transfer heat of the oil or refrigerant flowing inside the heat transfer tube 130 to the adsorbent 120.
도 1을 참조하면, 본 발명의 일 실시예에 따른 열발생장치(100)의 전열관(130)은 오일분리기(31)에서 분리된 오일이 다시 압축기로 되돌아가는 유로에 배치될 수 있다. 전열관(130)은 순환유로(33)와 상호 연통되게 연결될 수 있다.Referring to FIG. 1, the heat transfer tube 130 of the heat generator 100 according to an embodiment of the present invention may be disposed in a flow path in which oil separated from the oil separator 31 is returned to the compressor. The heat transfer tube 130 may be connected to communicate with the circulation passage 33.
오일분리기(31)에서 순환유로(33)에 흐르는 고온의 오일을 전열관(130)으로 흐르게 하여 전열관(130)을 감싸는 흡착제(120)가 오일의 열을 흡수해 흡착된 매질을 탈착할 수 있다. 이 때, 흡착제(120)는 재생되고 재차 흡착제로 냉매가 흡착 가능한 상태가 된다. The high temperature oil flowing in the circulation passage 33 in the oil separator 31 flows to the heat transfer tube 130, so that the adsorbent 120 surrounding the heat transfer tube 130 absorbs heat of the oil to desorb the adsorbed medium. At this time, the adsorbent 120 is regenerated and the refrigerant can be adsorbed again with the adsorbent.
이러한 구성에 의하여, 난방 운전시 오일분리기(31)에서 분리된 오일을 전열관(130)으로 유동되도록 하여 순환되는 오일의 열을 이용하여 흡착제(120)를 재생하도록 한다.By such a configuration, the oil separated in the oil separator 31 during the heating operation is allowed to flow to the heat transfer tube 130 to regenerate the adsorbent 120 using the heat of the oil circulated.
종래에는 난방에 필요한 열의 일부를 제상시에 사용하기 위해 축열조에 축적하여 난방 성능이 떨어져 사용자의 체감 불량을 발생하는 문제가 있었다. 이에 반해, 본 발명의 일 실시예에 따른 공기조화기(1)는 사용하지 않는 순환되는 오일이 갖는 열을 이용하는 것이므로 사용자의 난방 체감성능을 향상시킬 수 있고, 남는 열을 재활용하는 것으로 공기조화기의 에너지 효율을 향상시킬 수 있다.In the related art, a part of the heat required for heating is accumulated in the heat storage tank for use in defrosting, and thus, the heating performance is poor, resulting in a poor user experience. On the contrary, since the air conditioner 1 according to the embodiment of the present invention uses heat of circulated oil that is not in use, the user's heating sensation performance can be improved, and the air conditioner is recycled by remaining heat. It can improve the energy efficiency.
흡착제의 재생에 필요한 열을 흡수할 수 있도록 흡착제(120)와 전열관(130)은 직접 접촉하도록 배치된다. 또한, 전열관(130)과 흡착제(120)와의 접촉면적을 늘리기 위해 전열관은 다양한 형태로 형성될 수 있다. The adsorbent 120 and the heat transfer tube 130 are disposed in direct contact with each other so as to absorb heat required for regeneration of the adsorbent. In addition, in order to increase the contact area between the heat transfer tube 130 and the adsorbent 120, the heat transfer tube may be formed in various forms.
도 2b 및 도 2c는 도 2a에 도시된 전열관의 변형된 예를 나타낸다. 2B and 2C show a modified example of the heat pipe shown in FIG. 2A.
도 2b를 참조하면, 전열관(131)은 흡착제(120)와의 접촉면적을 늘리기 위해 탱크(110) 내에서 분기되어 병렬로 연결된 2개 이상의 관(133, 135)으로 형성될 수 있다. Referring to FIG. 2B, the heat transfer tube 131 may be formed of two or more tubes 133 and 135 branched in the tank 110 and connected in parallel to increase the contact area with the adsorbent 120.
도 2c를 참조하면, 전열관(139)은 흡착제(120)에 효율적으로 열을 전달할 수 있도록 확장된 접촉면적을 가지도록 탱크(110) 내에 위치하는 구간이 지그재그 형상으로 형성될 수 있다.Referring to FIG. 2C, the heat transfer tube 139 may have a zigzag shape in a section located in the tank 110 to have an extended contact area to efficiently transfer heat to the adsorbent 120.
도3은 본 발명의 일 실시예에 따른 공기조화기의 제상 운전을 설명하는 도면이다. 3 is a view for explaining a defrosting operation of the air conditioner according to an embodiment of the present invention.
도 3을 참조하면, 공기조화기(1)의 제상 운전시(도 3의 화살표 방향)에는, 냉매가 압축기(21), 오일분리기(31), 사방밸브(25), 실외 열교환기(23), 실외팽창장치(29), 실내 열교환기(13), 사방밸브(25), 제1 바이패스관(61), 열발생장치(100), 제2 바이패스관(62), 어큐뮬레이터(27), 압축기(21) 순으로 순환되는 냉매 사이클을 반복하게 된다.Referring to FIG. 3, during the defrosting operation of the air conditioner 1 (in the direction of the arrow in FIG. 3), the refrigerant is supplied to the compressor 21, the oil separator 31, the four-way valve 25, and the outdoor heat exchanger 23. , Outdoor expansion device (29), indoor heat exchanger (13), four-way valve (25), first bypass pipe (61), heat generator (100), second bypass pipe (62), accumulator (27) The refrigerant cycle circulated in the compressor 21 is repeated.
즉, 제상 운전 시에는 유입측 냉매관(51)으로부터 공급된 냉매가 열발생장치(100)를 거쳐 어큐뮬레이터(27)로 순환하게 된다.That is, during the defrosting operation, the refrigerant supplied from the inflow refrigerant pipe 51 is circulated to the accumulator 27 via the heat generating device 100.
구체적으로, 제상 운전시 압축기(21)에서 유출되는 고온 고압의 기체 냉매는 실외 열교환기(23)로 유입되어 착상된 서리를 제거한다. 이 때, 유입측 냉매관(51)으로부터 제1 바이패스관(61)으로 유입되는 냉매를 열발생장치(100)에서 물리 흡착하여 발열할 수 있도록 한다. 열발생장치(100)의 흡착열에 의해 가열된 냉매는 제2 바이패스관(62)으로 배출된다.Specifically, the high temperature and high pressure gas refrigerant flowing out of the compressor 21 during the defrosting operation flows into the outdoor heat exchanger 23 to remove frost formed. At this time, the refrigerant flowing into the first bypass pipe 61 from the inlet refrigerant pipe 51 is physically adsorbed by the heat generating device 100 to generate heat. The refrigerant heated by the heat of adsorption of the heat generator 100 is discharged to the second bypass pipe 62.
제상 운전 시에 열발생장치(100)는 보조 열원으로서 흡착제(120)와 냉매의 물리 흡착에 따른 발열반응으로 냉매를 가열시켜 고온의 냉매로 변환시킨다. 제2 바이패스관(62)으로 배출된 냉매는 어큐뮬레이터(27), 압축기(21)를 거쳐 고온 고압 기체로 변환되어 실외 열교환기(23)의 착상된 서리를 제거할 수 있다. 이 때, 제1바이패스관(61)에 형성된 제 1개폐 밸브(V1)가 개방되어 메인관(60)을 흐르는 냉매의 일부는 열발생장치(100)로 유입된다. 도 3에서는 메인관(60)에 흐르는 냉매의 일부가 열발생장치(100)로 유입되는 것으로 도시하였지만, 이에 한정되지 않고, 분기되는 지점(P1)에 유로 전환 밸브(미도시)를 설치하여 메인관(60)에 흐르는 냉매 전부가 열발생장치(100)를 경유해서 어큐뮬레이터(27)로 흡입되는 경우도 포함된다.In the defrosting operation, the heat generating device 100 converts the refrigerant into a high temperature refrigerant by heating an exothermic reaction according to physical adsorption of the adsorbent 120 and the refrigerant as an auxiliary heat source. The refrigerant discharged into the second bypass pipe 62 may be converted into high temperature and high pressure gas through the accumulator 27 and the compressor 21 to remove the frost formed on the outdoor heat exchanger 23. At this time, the first opening / closing valve V1 formed in the first bypass pipe 61 is opened, and a part of the refrigerant flowing through the main pipe 60 flows into the heat generating device 100. In FIG. 3, a part of the refrigerant flowing in the main pipe 60 is introduced into the heat generating device 100, but the present invention is not limited thereto. It also includes a case where all of the refrigerant flowing through the pipe 60 is sucked into the accumulator 27 via the heat generator 100.
유입측 냉매관(51)을 통해 유입된 냉매가 제1 및 제2 바이패스관(61, 62)을 통해 열발생장치(100)를 경유하여 유동하는 냉매 사이클을 순환하는 과정을 반복하면서 공기조화기(1)는 제상 기능을 수행하게 된다.Air conditioning while repeating the process of circulating the refrigerant cycle flowing through the heat generating device 100 through the heat generating device 100 through the first and second bypass pipes 61 and 62 The machine 1 performs a defrost function.
한편, 제상 시에 열발생장치(100)에서 흡착제(120)에 대한 냉매 탈착을 방지하기 위해 오일분리기(31)에서 분리된 오일이 열발생장치(100)의 전열관(130)에 흐르지 않도록 순환유로(60)는 제2 개폐 밸브(V2)에 의해 폐쇄된다. Meanwhile, in order to prevent desorption of the refrigerant to the adsorbent 120 from the heat generator 100 at the time of defrosting, the circulating flow path does not flow the oil separated from the oil separator 31 to the heat transfer pipe 130 of the heat generator 100. 60 is closed by the 2nd open / close valve V2.
한편, 제상이 완료되면 압축기(21)에서 토출된 냉매가 실내 열교환기(13)로 유동하여 난방 운전을 수행하게 된다.On the other hand, when the defrost is completed, the refrigerant discharged from the compressor 21 flows to the indoor heat exchanger 13 to perform the heating operation.
도4은 본 발명의 일 실시예에 따른 공기조화기의 난방 운전을 설명하는 도면이다.4 is a view for explaining the heating operation of the air conditioner according to an embodiment of the present invention.
도 4를 참조하면, 공기조화기(1)의 난방 운전시(도 4의 화살표 방향) 압축기(21)에 의해 압축된 냉매는 오일분리기(31)를 거쳐 사방밸브(25)에 의해 실내 열교환기(13), 실외팽창장치(29), 실외 열교환기(23), 사방밸브(25), 어큐뮬레이터(27), 압축기(21) 순으로 순환되는 냉매 사이클을 반복하게 된다.Referring to FIG. 4, the refrigerant compressed by the compressor 21 during the heating operation of the air conditioner 1 (in the direction of the arrow in FIG. 4) is passed through the oil separator 31 to the indoor heat exchanger by the four-way valve 25. (13), the outdoor expansion device (29), the outdoor heat exchanger (23), the four-way valve (25), the accumulator (27), the compressor cycle circulated in the order of the compressor 21 is repeated.
구체적으로, 난방 운전 시에는 저온, 저압의 기체 냉매가 압축기(21)에 의해 고온, 고압의 기체 냉매로 압축되고, 이렇게 압축된 냉매는 사방밸브(25)에 의해 실내 열교환기(13)측으로 공급되어 실내 공기와 열교환되면서 고온, 고압 상태로 실내 열교환기(13)를 통과하게 된다. 이때, 실내 열교환기(13) 일측에 설치되는 실내팬(미도시)이 회전하여 공기를 유동시킴에 따라 실내의 찬 공기는 실내 열교환기(13) 측으로 공급되며 실내 열교환기(13) 내를 유동하는 고온, 고압의 액체 냉매와 열교환함에 따라 더운 공기로 변환되고, 이렇게 변환된 더운 공기는 계속되는 실내팬(미도시)의 회전에 따라 실내로 토출되어 실내는 난방되게 된다.Specifically, during the heating operation, the low-temperature, low-pressure gas refrigerant is compressed by the compressor 21 into the high-temperature, high-pressure gas refrigerant, and the compressed refrigerant is supplied to the indoor heat exchanger 13 by the four-way valve 25. The heat exchanger passes through the indoor heat exchanger 13 at a high temperature and high pressure while being heat-exchanged with the indoor air. At this time, as the indoor fan (not shown) installed on one side of the indoor heat exchanger 13 rotates and flows the air, the cold air of the room is supplied to the indoor heat exchanger 13 and flows through the indoor heat exchanger 13. The hot air is converted into hot air by heat exchange with a high-temperature, high-pressure liquid refrigerant. The hot air is then discharged into the room as the indoor fan (not shown) continues to rotate, thereby heating the room.
또한, 실내 열교환기(13)를 통과하면서 과냉된 액체 상태의 냉매는 실외팽창장치(29)를 지나면서 압력과 온도가 급격히 떨어져 다시 저온, 저압의 기액혼합 상태의 냉매로 변한 다음 실외 열교환기(23)로 유입되고, 실외 열교환기(23)로 유입된 냉매는 실외 열교환기(23)를 지나면서 주위의 열을 흡수하여 저온, 저압의 기체 상태로 변환된다.In addition, the refrigerant in the liquid state, which has been supercooled while passing through the indoor heat exchanger 13, rapidly passes through the outdoor expansion device 29, so that the pressure and temperature drop rapidly, and the refrigerant is changed into a refrigerant having a low temperature and low pressure gas-liquid mixture, and then the outdoor heat exchanger ( 23, the refrigerant introduced into the outdoor heat exchanger (23) absorbs the surrounding heat while passing through the outdoor heat exchanger (23) and is converted into a gas state of low temperature and low pressure.
난방시에는 열발생장치(100)를 경유하지 않고, 어큐뮬레이터(27)로 유동할 수 있도록 제1 개폐밸브(V1)에 의해 바이패스관(61)은 폐쇄된다.At the time of heating, the bypass pipe 61 is closed by the first opening / closing valve V1 so as to flow to the accumulator 27 without passing through the heat generating device 100.
공기조화기(1)의 난방 운전시 열발생장치(100)의 흡착제(120)를 재생하기 위해, 오일분리기(31)의 유출측과 연결된 순환유로(33)는 제2 개폐밸브(V2)에 의해 개방한다. 순환유로(33)와 상호 연통된 전열관(130)에 고온의 오일이 흐르게 되고, 오일의 열을 전열관(130)을 통해 흡착제(120)로 전달한다. 열을 전달받아 흡착된 냉매가 흡착제(120)의 표면으로부터 분리되어 흡착제(120)는 다시 흡착할 수 있는 상태가 된다. In order to regenerate the adsorbent 120 of the heat generator 100 during the heating operation of the air conditioner 1, the circulation passage 33 connected to the outlet side of the oil separator 31 is connected to the second on / off valve V2. By opening. High temperature oil flows through the heat transfer tube 130 in communication with the circulation passage 33, and transfers heat of the oil to the adsorbent 120 through the heat transfer tube 130.

도 6를 참조하여, 본 발명의 또 다른 실시예에 따른 공기조화기(1)를 설명한다. 다른 실시예의 구성을 설명함에 있어, 도 1 에서 상술한 실시예와 동일한 실외기(20) 및 실내기(10)의 구성에 대해서는 동일한 부재번호를 부여하였으며, 동일한 구성에 대한 구체적인 설명을 생략한다. 도1의 실시예와 상이한 복수의 실외 열교환기(23)와 연결 유로에 대해서만 설명한다.6, an air conditioner 1 according to still another embodiment of the present invention will be described.

Only a plurality of outdoor heat exchangers 23 and connection flow paths different from those of the embodiment of FIG. 1 will be described.
도 1의 실시예에 따른 공기조화기(1)는 단일의 실외 열교환기(23)를 구비하는 것이었으나, 도 6에 나타난 바와 같이 공기조화기(1)는 복수의 실외 열교환기(23A, 23B)를 구비하도록 구성할 수 있다. 각 실외 열교환기(23A, 23B)에 대응하여 연결관(70A, 70B))이 설치되어 있다. 도 6에서는 2개의 실외 열교환기(23A, 23B)를 구비한 것으로 도시하였으나, 이에 한정되지 않고, 2개 이상의 실외 열교환기를 구비할 수 있다.The air conditioner 1 according to the embodiment of FIG. 1 has a single outdoor heat exchanger 23, but as shown in FIG. 6, the air conditioner 1 includes a plurality of outdoor heat exchangers 23A and 23B. It can be configured to have). Coupling pipes 70A and 70B are provided corresponding to the outdoor heat exchangers 23A and 23B. In FIG. 6, two outdoor heat exchangers 23A and 23B are illustrated. However, the present disclosure is not limited thereto, and two or more outdoor heat exchangers may be provided.
