Description
본 발명은 냉난방용 히트펌프에 관한 것으로, 특히 난방운전을 기준으로 설계된 실외기의 냉방운전시 냉매의 과다 응축으로 인한 손실을 저감시키기 위한 실외기의 사이클 구조에 관한 것이다.The present invention relates to a heat pump for cooling and heating, and more particularly, to a cycle structure of an outdoor unit for reducing a loss due to excessive condensation of a refrigerant during the cooling operation of an outdoor unit designed based on a heating operation.
도 1은 종래 히트펌프의 냉난방 사이클을 나타낸 것으로써, 개략적인 구성을 살펴보면 저온저압의 냉매를 흡입하여 고온고압의 냉매로 압축 토출하는 압축기(3)와, 압축기(3)에서 압축되어 토출되는 냉매의 방향을 냉방시에는 실외측 열교환기(2)로 난방시에는 실내측 열교환기(1)로 각각 변환시켜주도록 하는 사방변(4)과, 사방변(4)과 냉매라인으로 연결되어 냉방시에는 증발기로써 난방시에는 응축기로써 작용하는 실내측 열교환기(1)와, 실내측 열교환기(1)와 정류회로(5)에 의해 접속되어 난방시에는 증발기로 냉방시에는 응축기로 작용하는 실외측 열교환기(2)로 이루어진다. 또한, 정류회로(5)에는 체크밸브(6)가 설치되어 냉난방에 관계없이 항상 한쪽 방향으로만 냉매가 통과되는 일방향 냉매라인이 형성되어 있고, 일방향 냉매라인상에는 수액기(8)와 팽창변(7)이 순차적으로 구성되어 있다.1 shows a cooling / heating cycle of a conventional heat pump. Referring to the schematic configuration, a compressor 3 which sucks low-temperature low-pressure refrigerant and compresses and discharges the refrigerant at a high-temperature high-pressure refrigerant, and a refrigerant compressed and discharged by the compressor 3 are illustrated in FIG. When the direction of cooling is connected to the outdoor side heat exchanger (2) and the indoor side heat exchanger (1) when heating, the four sides and four sides and the refrigerant line is connected to the cooling line Is connected by an indoor heat exchanger (1) which acts as a condenser when heating as an evaporator, and an indoor heat exchanger (1) and a rectifier circuit (5). It consists of a heat exchanger (2). In addition, the rectifier circuit 5 is provided with a check valve 6 is provided with a one-way refrigerant line through which the refrigerant always passes in one direction irrespective of heating and cooling, the receiver 8 and the expansion valve (7) on the one-way refrigerant line ) Are sequentially configured.
한편, 실외기 본체 내부의 실외측 열교환기(2)에는 열교환을 위해 강제 송풍을 하는 송풍팬(10)이 두 개가 설치되어 있는데, 통상적으로 히트펌프는 냉방과 난방을 냉매의 응축과 증발을 이용한 냉동 싸이클을 적용하기 때문에 실내를 냉방만 하는 냉방전용 냉동싸이클에 비해 실외측 열교환기의 크기가 훨씬 크다. 따라서 일반적으로 실외기의 송풍팬은 하나 이상이며 보통 2개로 이루어진다.On the other hand, in the outdoor heat exchanger (2) inside the outdoor unit main body is provided with two blowing fans 10 for forced air for heat exchange, the heat pump is a refrigeration using the condensation and evaporation of the refrigerant cooling and heating typically Since the cycle is applied, the size of the outdoor heat exchanger is much larger than that of the refrigeration cycle dedicated to cooling the room. Therefore, the blower fan of the outdoor unit is generally one or more, usually two.
실외측 열교환기(2)가 커야하는 이유는 난방시에 실내측 열교환기(1)에서 고온 고압의 가스냉매가 실내의 차가운 공기와 열교환하여 응축을 하게 되는데, 이때 고온 고압의 가스냉매는 액상으로 변하면서 열을 방출하게 되고 방출된 열에 의해 실내의 공기가 따뜻하게 된다. 그와 반대로 실외측 열교환기(2)에서는 저온 저압의 액냉매가 실외의 공기와 열교환하여 실외 공기로부터 열을 빼앗아 자신은 기체로 증발하는 증발작용을 하여야 하는데, 난방이란 통상적으로 겨울철에 행하는 것으로 실외측 공기는 매우 낮은 상태이기 때문에 실외측 열교환기(2)를 통하는 액냉매가 차가운 실외측 공기로부터 열을 빼앗기란 매우 어렵다. 따라서 액상의 냉매가 실외측 열교환기(2)를 통과할 때 기상으로 증발하는데 시간이 걸리기 때문에 증발을 위한 경로가 길어질 수 밖에 없는 것이다.The reason why the outdoor heat exchanger (2) should be large is that the high temperature and high pressure gas refrigerant condenses by heat exchange with the cold air in the indoor heat exchanger (1) during heating. They change and release heat, and the heat released makes the air in the room warm. On the contrary, in the outdoor heat exchanger (2), the low-temperature and low-pressure liquid refrigerant exchanges heat with outdoor air to take heat away from the outdoor air and evaporate itself into a gas, which is usually performed in winter. Since the side air is in a very low state, it is very difficult for the liquid refrigerant through the outdoor side heat exchanger 2 to lose heat from the cold outdoor air. Therefore, since the liquid refrigerant takes time to evaporate in the gas phase when passing through the outdoor heat exchanger (2), the path for evaporation will be long.
상기와 같은 사이클 구조를 갖는 종래 히트펌프의 동작을 살펴보기로 한다.The operation of the conventional heat pump having the cycle structure as described above will be described.
먼저, 난방시에는 압축기(3)로부터 압축된 고온고압의 기상의 냉매가 토출되고 사방변(4)에 의해 실내측 열교환기(1)로 그 흐름 방향이 유도되며 실내측 열교환기(1)로 유도된 기상의 냉매는 응축되어 열을 방출하면서 실내의 공기가 따뜻해 지게 된다. 상기 냉매는 실내측 열교환기(1)를 통과하면서 액상의 냉매로 변하게 되고 팽창변(7)을 통과하면서 압력강하되어 저온 저압의 액냉매로 변하게 되어 정류회로(5)를 거쳐 실외측 열교환기(2)로 유도된다. 실외측 열교환기(2)로 유도된 액상의 냉매는 실외측의 차가운 공기로부터 열을 빼앗아 증발하면서 기상의 냉매로 변하고 사방변(4)의 유도에 의해 압축기(3)의 흡입측으로 흡입되어 다시 고온 고압의 기체 냉매로 압축되어 토출된다. 난방시에는 상기의 과정이 연속적으로 되면서 실내를 난방하게 되는 것이다.First, during heating, the compressed high-temperature, high-pressure gaseous refrigerant is discharged from the compressor (3), and the flow direction is induced to the indoor heat exchanger (1) by the four sides (4), and to the indoor heat exchanger (1). The induced gaseous refrigerant condenses and releases heat, causing the air in the room to warm up. The refrigerant is changed into a liquid refrigerant while passing through the indoor heat exchanger (1), and the pressure is dropped while passing through the expansion valve (7) to become a liquid refrigerant of low temperature and low pressure through the rectification circuit (5) through the outdoor heat exchanger (2). Is induced. The liquid refrigerant induced by the outdoor heat exchanger (2) takes heat from the cold air of the outdoor side and evaporates to a gaseous refrigerant while being sucked into the suction side of the compressor (3) by induction of the four-sided (4) and again heated to a high temperature. It is compressed and discharged into a high-pressure gas refrigerant. At the time of heating, the above process is continued to heat the room.
한편, 냉방시에는 난방운전과는 반대로 사이클이 진행 되는데, 압축기(3)로부터 압축된 고온 고압의 기상의 냉매가 토출되고, 사방변(4)에 의해 실외측 열교환기(2)로 그 흐름 방향이 유도되며, 실외측 열교환기로 유도된 기상의 냉매는 응축되어 열을 방출하면서 실외측 열교환기(2)를 통과하여 액상의 냉매로 변해 실내측 열교환기(1)로 유도된다. 상기 실내측 열교환기로 유도된 액상의 냉매는 실내측의 공기로부터 열을 빼앗아 증발하면서 실내의 공기를 냉각시키게 된다. 이렇게 증발을 하면서 액냉매는 기상의 냉매로 변하고 사방변(4)의 유도에 의해 압축기(3)의 흡입측으로 흡입되어 다시 고온 고압의 기체 냉매로 압축되어 토출된다. 냉방시에는 상기의 과정이 연속적으로 되면서 실내를 냉방하게 되는 것이다.On the other hand, during cooling, the cycle proceeds in contrast to the heating operation, and the refrigerant of the high temperature and high pressure gaseous phase compressed from the compressor 3 is discharged, and the flow direction is directed to the outdoor heat exchanger 2 by the four sides 4. The refrigerant in the gas phase guided to the outdoor side heat exchanger is condensed and discharges heat, passes through the outdoor side heat exchanger (2), becomes a liquid phase refrigerant, and is led to the indoor side heat exchanger (1). The liquid refrigerant induced by the indoor heat exchanger cools the indoor air while evaporating by taking heat from the indoor air. While evaporating in this way, the liquid refrigerant turns into a gaseous refrigerant, is sucked to the suction side of the compressor 3 by the induction of the four sides, and is compressed and discharged again into a gaseous refrigerant of high temperature and high pressure. During cooling, the above process is continued to cool the room.
그러나 종래 히트펌프는 난방시 운전을 위하여 실외측 열교환기(2)의 크기를 일반의 냉방 전용 냉동싸이클에 비해 훨씬 크게 하는데, 이렇게 난방운전을 위해 확대된 실외측 열교환기를 이용하여 냉방을 하였을 경우, 기상의 액냉매가 상기 확대된 실외측 열교환기를 통과하면서 과도하게 응축되어 지나친 에너지의 낭비를 초래하게 되며, 상기 실외기에 구비되어 있는 송풍팬(10)의 구동을 위한 전력이 낭비되게 되는 문제점이 있었다.However, in the conventional heat pump, the size of the outdoor heat exchanger 2 is much larger than that of a general cooling refrigeration cycle for operation during heating. When the heat pump is cooled by using the expanded outdoor heat exchanger for heating operation, The liquid refrigerant in the gas phase is excessively condensed as it passes through the enlarged outdoor heat exchanger, resulting in waste of excessive energy, and there is a problem in that power for driving the blower fan 10 provided in the outdoor unit is wasted. .
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 히트펌프의 냉방운전시 실외기측 열교환기의 일부만으로 냉매를 유도하여 과다응축으로 인한 에너지낭비를 줄이고, 실외기의 유동을 분할하여 선택적으로 송풍팬을 작동하게 함으로써 소비전력을 저감할 수 있는 사이클 구조를 제공하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above to reduce the energy waste due to excessive condensation by inducing the refrigerant to only a part of the heat exchanger side of the outdoor unit during the cooling operation of the heat pump, by dividing the flow of the outdoor unit It is an object of the present invention to provide a cycle structure that can reduce power consumption by selectively operating the blower fan.

상기 목적을 실현하기 위한 본 발명의 기술적 수단은 실외측 열교환기를 다수의 영역으로 경로가 분산되도록 구성하고, 냉방시는 사방변으로부터 실외측 열교환기의 일부영역으로만 냉매가 유도될 수 있도록 하는 체크밸브를 구비하는 것이다.Technical means of the present invention for realizing the above object is configured to distribute the path to a plurality of areas of the outdoor heat exchanger, check the cooling can be guided to only a partial region of the outdoor heat exchanger from the four sides when cooling It is provided with a valve.
이하, 본 발명을 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명이 적용되는 히트펌프 사이클은 실외기측을 제외한 전체적인 구조가 종래와 동일하게 이루어 짐으로 이하에서는 그 이외의 구성설명을 생략하고 종래와 동일한 도면부호를 부여하기로 한다.In the heat pump cycle to which the present invention is applied, the overall structure except for the outdoor unit is made in the same manner as in the prior art, and hereinafter, other components will be omitted and the same reference numerals as in the prior art will be given.
도 2 는 본 발명에 의한 히트펌프의 냉난방 사이클 및 실외기측 구조를 나타낸 것으로, 실외측 열교환기(2)를 제1영역(A)과 제2영역(B)으로 양분하여 별도의 경로를 갖도록 하고, 사방변(4)으로부터 실외측 열교환기(2)에 접속되는 냉매라인을 제1,2영역(A,B)에 각각 분기하도록하여 상기 양분된 실외측 열교환기 영역중 하나에 연결되는 냉난방용 냉매라인(a)과 나머지 다른 영역에 연결되는 난방용 냉매라인(b)을 구성하고, 제1,2영역(A,B)으로부터 각각 분기된 냉매라인은 실내측 열교환기(미도시) 측으로 연결되도록 구성한다. 특히, 난방용 냉매라인은 난방시에 냉매가 사방변(4)측으로만 흐르도록 체크밸브(12)를 구비하였다.2 is a view illustrating a cooling / heating cycle and an outdoor unit side structure of a heat pump according to the present invention. The outdoor side heat exchanger 2 is divided into a first area A and a second area B so as to have a separate path. For cooling and heating connected to one of the divided outdoor side heat exchanger regions by branching the refrigerant lines connected to the outdoor side heat exchanger 2 from the four sides 4 to the first and second regions A and B, respectively. It constitutes a refrigerant line (b) for heating connected to the refrigerant line (a) and the other areas, and the refrigerant lines branched from the first and second regions (A, B), respectively, to be connected to the indoor heat exchanger (not shown). Configure. In particular, the heating refrigerant line is provided with a check valve 12 so that the refrigerant flows only to the four sides 4 at the time of heating.
한편, 양분된 실외측 열교환기(2)의 경계부분을 중심으로 실외기 내부를 구획하는 격벽(13)을 설치하고, 송풍팬(10,10')을 구획된 실외기 본체 내에 각각 취부한다. 격벽(13)은 실외기 내부에서 덕트를 형성하여 줌으로써 송풍기에 의한 유로가 서로 간섭되지 않고 원활한 유동을 이루도록 하며, 냉방시에는 냉매가 차단된 실외측 열교환기(2) 영역에 대응되는 송풍팬(10')은 운전을 정지 하도록 한다.On the other hand, the partition 13 which partitions the inside of an outdoor unit is provided centering around the boundary part of the bilateral outdoor side heat exchanger 2, and blower fans 10 and 10 'are respectively mounted in the partitioned outdoor unit main body. The partition wall 13 forms a duct in the outdoor unit so that the flow paths of the blowers achieve smooth flow without interfering with each other, and during cooling, the blower fan 10 corresponding to the area of the outdoor heat exchanger 2 in which the refrigerant is blocked. ') Stops the operation.
통상적으로 히트펌프에서의 실외측 열교환기(2)는 응축이나 증발하는 영역과 과냉각 영역이라고 하는 서로 다른 경로로 분리되어 있는데, 상기 과냉각 영역은 난방시 실외측 열교환기에서 증발작용이 일어나면서 실외측 열교환기 표면에 물방울들이 얼어버리는 현상이 발생한다. 이를 방지하기 위하여 실내측 열교환기에서 응축된 고온고압의 액냉매의 일부를 압력강하 시키지 않고 바로 상기 과냉각영역으로 통과시켜 실외측 열교환기(2)를 녹이도록 하는 것도 존재하고 있다.Typically, the outdoor heat exchanger (2) in the heat pump is separated into different paths called condensation or evaporation zones and subcooling zones. Water droplets freeze on the surface of the heat exchanger. In order to prevent this, some of the high-temperature, high-pressure liquid refrigerant condensed in the indoor heat exchanger may be passed directly to the subcooling region to melt the outdoor heat exchanger 2 without pressure drop.
본 발명의 제1,2영역(A,B)이란 상기에서 언급한 통상의 히트펌프 실외측 열교환기가 갖는 과냉각영역은 포함하지 않는 것으로 증발이나 응축이 일어나는 영역만을 대상으로 하는 것임을 밝혀둔다.The first and second regions A and B of the present invention do not include the subcooling region of the aforementioned heat pump outdoor side heat exchanger, and are intended to cover only the region where evaporation or condensation occurs.
이와같이 구성되는 본 발명 히트펌프의 동작을 살펴보기로 한다.The operation of the heat pump of the present invention configured as described above will be described.
먼저, 난방시에는 압축기(3)로부터 압축된 고온 고압의 기상의 냉매가 토출되고 사방변(4)에 의해 실내측 열교환기로 그 흐름방향이 유도되고 실내측 열교환기로 유도된 기상의 냉매는 응축되어 열을 방출하면서 실내의 공기가 따뜻해지게 된다. 상기 냉매는 실내측 열교환기를 통과하면서 액상의 냉매로 변하게 되고, 팽창변을 통과하면서 압력강하되어 저온 저압의 액냉매로 변하게 되어 실외측 열교환기(2)로 유도된다. 이때, 액냉매는 실외측 열교환기의 제1,2영역(A,B)으로 각각 양분되어 유도된 후 실외측의 차가운 공기로부터 열을 빼앗아 증발하면서 기상의 냉매로 변하고 냉난방용 냉매라인(a)과 난방용 냉매라인(b)을 지나서 사방변(4)의 유도에 의해 압축기(3)로 흡입되어 다시 고온고압의 기체 냉매로 압축되어 토출되면서 난방사이클이 순환되는 것이다.First, during heating, the high-temperature, high-pressure gaseous refrigerant compressed from the compressor 3 is discharged, the flow direction is induced to the indoor heat exchanger by the four-sided sides 4, and the gaseous refrigerant induced by the indoor heat exchanger is condensed. The air in the room becomes warm as it releases heat. The refrigerant is changed into a liquid refrigerant while passing through the indoor side heat exchanger, and the pressure is dropped while passing through the expansion side to be a liquid refrigerant of low temperature and low pressure, and is led to the outdoor side heat exchanger (2). At this time, the liquid refrigerant is divided into the first and second zones (A, B) of the outdoor heat exchanger, respectively, is induced, and then takes the heat from the cold air of the outdoor side and evaporates it into a gaseous refrigerant and cools and cools the refrigerant line (a). The heating cycle is circulated while being sucked into the compressor 3 by the induction of the four sides 4 through the heating refrigerant line b and is compressed and discharged again into a high-temperature, high-pressure gas refrigerant.
이때, 실외기는 제1,2영역(A,B)의 경계부분을 중심으로 격벽(13)으로 구획되어 있기 때문에 두 대의 송풍팬(10,10')의 회전에 의한 유동간섭이 일어나지 않아 원활한 유동이 생성되어 열교환을 촉진하고, 유동간섭에 의한 손실을 제거할 수 있게 된다.At this time, since the outdoor unit is partitioned by partitions 13 around the boundary portions of the first and second regions A and B, flow interference due to the rotation of the two blowing fans 10 and 10 'does not occur and thus smooth flow. This can be generated to promote heat exchange and to eliminate losses due to flow interference.
그리고 냉방시에는 상기 난방운전과는 반대로 진행되는데, 압축기(3)로부터 압축된 고온고압의 기상의 냉매가 토출되고 사방변(4)에 의해 실외측 열교환기(2)로 유도되는데, 상기 유도되는 냉매는 체크밸브(12)에 의해 제2영역(B)으로는 유도되지 않고 제1영역(A)으로만 유도된다. 제1영역(A)으로 유도된 기상의 냉매는 응축되어 열을 방출하면서 액상의 냉매로 변하게 되고 팽창변을 통과하면서 압력강하되어 저온저압의 액냉매로 변하게 된 후 실내측 열교환기로 유도된다. 실내측 열교환기로 유도된 액상의 냉매는 실내측의 공기로부터 열을 빼앗아 증발하면서 실내의 공기를 냉각시키게 된다. 이와같이 증발을 하면서 액냉매는 기상의 냉매로 변하고 사방변(4)의 유도에 의해 압축기(3)로 흡입되어 다시 고온 고압의 기체 냉매로 압축된 후 토출되는 사이클을 이루며 냉방을 수행하게 되는 것이다.In the cooling process, the heating operation is performed in the reverse direction. The high-temperature, high-pressure gaseous refrigerant compressed from the compressor 3 is discharged and guided to the outdoor heat exchanger 2 by the four-sided sides 4. The refrigerant is guided only to the first region A, not to the second region B by the check valve 12. The refrigerant in the gaseous phase guided to the first region (A) is condensed to change into a liquid refrigerant while releasing heat, and the pressure is dropped while passing through an expansion valve to change into a liquid refrigerant of low temperature and low pressure, and then led to an indoor heat exchanger. The liquid refrigerant induced by the indoor heat exchanger cools the indoor air while taking heat away from the indoor air. As the liquid evaporates as described above, the liquid refrigerant is changed into a refrigerant in a gaseous phase, is sucked into the compressor 3 by the induction of the four sides, and is compressed into a gaseous refrigerant of high temperature and high pressure, and then discharged, thereby cooling.
특히, 냉방시에는 제어부(미도시)가 냉매가 유도되지 않는 실외측 열교환기(2)의 제2영역(B)에 대향되는 송풍팬(10')은 전원공급을 차단하게 된다. 따라서, 제1영역(A)에 대향되는 송풍팬(10) 하나로만 운전을 할 수 있으므로 지나치게 소비되는 전력의 낭비를 줄일 수 있으며, 냉방시 냉매의 유도를 실외측 열교환기(2)의 일부에만 하도록 하므로 필요이상으로 냉매가 응축되는 것을 방지하여 에너지를 절약할 수 있고, 열교환기를 효율적으로 사용 가능하며, 실외기내에 격벽(13)을 형성하므로써 냉방시 일측 송풍팬만을 동작시키더라도 나머지 부분으로 송풍압이 분산되는 것을 방지하여 효과적인 사이클의 이용이 가능하게 된다.In particular, during cooling, the blowing fan 10 ′ facing the second area B of the outdoor heat exchanger 2 where the coolant is not guided cuts off the power supply. Therefore, since only one blower fan 10 facing the first region A can be operated, it is possible to reduce waste of excessively consumed power, and to induce the refrigerant during cooling to only a part of the outdoor heat exchanger 2. Since the refrigerant can be condensed more than necessary to save energy, the heat exchanger can be used efficiently, and the partition 13 is formed in the outdoor unit so that only one blower fan is operated during cooling, and the blower pressure is applied to the remaining part. This dispersion can be prevented and an effective cycle can be used.
이상 설명한 바와같이 본 발명의 히트펌프 사이클은 동작중 특히, 냉방운전시 실외기측 열교환기의 일부만으로 냉매를 유도하여 과다응축으로 인한 에너지 낭비를 제거하고, 실외기의 유동을 양분하여 일측팬을 작동하게하여 소비전력을 감소시키게 되는 효과가 있다.As described above, the heat pump cycle of the present invention removes energy waste due to overcondensation by guiding refrigerant to only a part of the outdoor unit side heat exchanger during the cooling operation, and divides the flow of the outdoor unit to operate one fan. Therefore, the power consumption is reduced.
