Description
본 발명은 실외열교환기와 실내열교환기의 냉매흐름을 변환시켜서 냉방과 난방을 선택적으로 수행하는 냉·난방 겸용 공기조화기에 관한 것으로, 특히 상기 실외열교환기의 공기흐름 방향 전방에 보조 응축기를 설치하여 난방운전시 실외열교환기의 서리 발생을 줄여 난방효율을 향상시키는 보조 응축기를 구비한 냉·난방 겸용 공기조화기에 관한 것이다.The present invention relates to a cooling / heating combined air conditioner for selectively cooling and heating by converting a refrigerant flow of an outdoor heat exchanger and an indoor heat exchanger, and in particular, by installing an auxiliary condenser in front of the air flow direction of the outdoor heat exchanger. The present invention relates to a cooling / heating combined air conditioner having an auxiliary condenser that improves heating efficiency by reducing frost of an outdoor heat exchanger during operation.
일반적인 냉·난방 공기조화기는 도 1에 나타난 바와 같이, 압축기(1), 실외열교환기(2), 모세관(11) 및 실내열교환기(4)가 냉매관(6)을 통해 순차적으로 연설되어 냉매를 순환시켜서 실내에 대해 냉방공조를 수행하는 냉방전용 공기조화기에 있어서, 상기 압축기(1), 실외열교환기(2) 및 실내열교환기(4) 사이의 냉매관로상에 사방밸브(5)를 설치하여 사방밸브(5)에 의해 압축기(1)에서 토출된 냉매를 냉방운전시에는 실외열교환기(2)로, 난방운전시에는 실내열교환기(3)로 순환시켜서 실내에 대해 냉·난방공조를 수행하는 것이다.As shown in FIG. 1, a typical cooling / heating air conditioner includes a compressor 1, an outdoor heat exchanger 2, a capillary tube 11, and an indoor heat exchanger 4 that are sequentially addressed through the refrigerant tube 6. In the air conditioner exclusively for cooling to circulate the air to perform the cooling air conditioning for the room, the four-way valve (5) is installed on the refrigerant pipe between the compressor (1), the outdoor heat exchanger (2) and the indoor heat exchanger (4) The refrigerant discharged from the compressor (1) by the four-way valve (5) is circulated to the outdoor heat exchanger (2) during the cooling operation and to the indoor heat exchanger (3) during the heating operation. To do.
냉방운전시 냉매사이클은 실선의 화설표→)와 같으며, 압축기(1)에서 토출된 고온 고압의 기체 냉매는 사방밸브(5)를 통해 실외열교환기(2)에서 실외 공기에 의해 냉각되어 응축열을 방출한 다음 모세관(3)에서 감압팽창되어 실내열교환기(4)에서 실내 공기의 열을 빼앗아 증발하여 실내 공기를 시원하게 한 다음 사방밸브(5)를 통해 압축기(1)에 흡입된다.In the cooling operation, the refrigerant cycle is the same as that of the solid line →), and the high temperature and high pressure gas refrigerant discharged from the compressor 1 is cooled by the outdoor air in the outdoor heat exchanger 2 through the four-way valve 5 to condense heat. After releasing the expansion and expansion under reduced pressure in the capillary tube (3) to take the heat of the indoor air from the indoor heat exchanger (4) to evaporate to cool the indoor air is sucked into the compressor (1) through the four-way valve (5).
난방운전시 냉매사이클은 점선의 화살표(→)와 같으며, 압축기(1)에서 토출된 고온 고압의 기체 냉매는 사방밸브(50를 통해 실내열교환기(4)에서 실내 공기에 의해 냉각되어 응축열을 방출하여 실내 공기를 따뜻하게 한 다음 모세관(3)에서 감압팽창되어 실외열교환기(2)에서 실외 공기의 열을 빼앗아 증발하여 실외 공기를 낮춘 다음 사방밸브(5)를 통해 압축기(1)에 흡입된다.During heating operation, the refrigerant cycle is the same as the dotted arrow (→), and the high temperature and high pressure gas refrigerant discharged from the compressor 1 is cooled by the indoor air in the indoor heat exchanger 4 through the four-way valve 50 to condense heat. It releases and warms the indoor air, expands under reduced pressure in the capillary tube (3), takes the heat of the outdoor air out of the outdoor heat exchanger (2), evaporates it, lowers the outdoor air, and is sucked into the compressor (1) through the four-way valve (5). .
여기에서, 난방운전시 냉매는 제1모세관(3a)에서 1차 감압팽창되고 다시 제2모세관(3b)에서 2차 감압팽창되어 제1모세관(3a)만을 통과한 경우 보다 더 증발하기 쉬운 상태가 되어 실외열교환기(2)에 유입되므로 실외열교환기(2)의 증발효율을 높이고, 냉방운전시 냉매는 역지밸브(7)에 의해 제1모세관(3a)만을 통과한다.Here, during the heating operation, the refrigerant is more easily evaporated than when the first pressure-expanded expansion in the first capillary tube 3a and the second pressure-expanded expansion in the second capillary tube 3b pass only through the first capillary tube 3a. Since the water is introduced into the outdoor heat exchanger 2, the evaporation efficiency of the outdoor heat exchanger 2 is increased, and the refrigerant passes only the first capillary tube 3a by the check valve 7 during the cooling operation.
한편, 난방운전시 냉매는 실외열교환기(2)에서 실외 공기의 열을 빼앗아 증발하며, 이에 따라 실외열교환기(2) 표면에 응축수가 발생하며, 실외온도가 낮은 경우 상기 응축수가 결빙되어 실외열교환기(2) 표면에 서리가 달라붙게 된다. 실외열교환기(2)에 서리가 발생하면 실외열교환기(2)의 열교환 효율이 떨어지게 된다.On the other hand, during the heating operation, the refrigerant takes the heat of the outdoor air from the outdoor heat exchanger (2) and evaporates. Accordingly, condensate is generated on the surface of the outdoor heat exchanger (2). Frost will stick to the surface of the machine 2. If frost occurs in the outdoor heat exchanger 2, the heat exchange efficiency of the outdoor heat exchanger 2 is reduced.
따라서 실외열교환기(2)의 서리를 제거하기 위해서 난방운전중 냉방운전상태로 전환하는 제상운전을 하며, 제상운전시 실외열교환기(2)는 응축기로, 실내열교환기(4)는 증발기의 역할을 담당한다. 이에 따라, 실외열교환기(2)에서 냉매가 응축되어 응축열을 발생하므로 실외열교환기(2)의 표면의 서리가 제거되며, 실내팬을 정지시켜서 실내로 찬바람이 토출되지 않도록 한다.Therefore, in order to remove the frost of the outdoor heat exchanger (2), the defrosting operation is switched to the cooling operation state during the heating operation. During the defrosting operation, the outdoor heat exchanger (2) serves as a condenser and the indoor heat exchanger (4) serves as an evaporator. In charge of. Accordingly, since the refrigerant is condensed in the outdoor heat exchanger 2 to generate condensation heat, frost on the surface of the outdoor heat exchanger 2 is removed, and the indoor fan is stopped to prevent cold air from being discharged to the room.
이와 같이, 난방운전중 실외열교환기(2)에 서리가 발생하면 제상운전(난방운전중 냉방운전)을 수행하고, 서리가 제거되면 다시 난방운전으로 복귀하게 된다.As described above, when frost occurs in the outdoor heat exchanger 2 during the heating operation, the defrosting operation (cooling operation during the heating operation) is performed, and when the frost is removed, the operation returns to the heating operation again.
그러나 종래의 냉·난방 겸용 공기조화기는 실외 온도가 낮을수록 난방운전중 실외열교환기에 서리가 많이 발생하며, 서리를 제거하기 위해 난방운전중 냉방운전을 하는 빈도수가 높아져서 실외열교환기의 효율이 떨어지는 문제점이 있었으며, 온도가 낮은 지역에서 냉·난방 겸용 공기조화기를 사용하기가 곤란한 문제점이 있었다.However, in the conventional air conditioner combined air conditioning system, the lower the outdoor temperature, the more frost is generated in the outdoor heat exchanger during the heating operation, and the frequency of the cooling operation during the heating operation is increased to remove the frost, so the efficiency of the outdoor heat exchanger is lowered. There was a problem that it is difficult to use a combined air-conditioning and air conditioner in a low temperature region.
본 발명은 상기의 결점을 해소하기 위한 것으로, 본 발명의 목적은 실외열교환기의 공기흐름 방향 전방에 보조 응축기를 설치하여 난방운전시 실외열교환기의 서리 발생을 줄여서 온도가 낮은 지역에서도 사용가능한 보조 응축기를 구비한 냉·난방 겸용 공기조화기를 제공하는데 있다.The present invention is to solve the above drawbacks, an object of the present invention is to install an auxiliary condenser in front of the air flow direction of the outdoor heat exchanger to reduce the occurrence of frost of the outdoor heat exchanger during heating operation can be used in low temperature region The present invention provides a cooling and heating air conditioner having a condenser.
본 발명은 압축기, 실외열교환기, 모세관 및 실내열교환기가 냉매관을 통해 순차적으로 연설되고, 상기 압축기, 실외열교환기 및 실내열교환기 사이에 사방밸브가 설치되어 상기 사방밸브에 의해 압축기에서 토출된 냉매를 냉방운전시에는 실외열교환기로, 난방운전시에는 실내열교환기로 순환시켜서 실내에 대해 냉·난방공조를 수행하는 냉·난방 겸용 공기조화기에 있어서, 상기 실외열교환기의 공기흐름 방향의 전방에 설치되는 보조 응축기를 구비한 것을 특징으로 한다.According to the present invention, a compressor, an outdoor heat exchanger, a capillary tube, and an indoor heat exchanger are sequentially delivered through a refrigerant pipe, and a four-way valve is installed between the compressor, the outdoor heat exchanger, and the indoor heat exchanger, and the refrigerant discharged from the compressor by the four-way valve. In a cooling and heating air conditioner for circulating the air to the outdoor heat exchanger during the cooling operation and the indoor heat exchanger during the heating operation to perform the cooling and heating air conditioning for the room, the outdoor heat exchanger is installed in front of the air flow direction An auxiliary condenser is provided.

본 발명의 실시예는 도 2에 나타낸 바와 같이, 압축기(1), 실외열교환기(2), 모세관(11) 및 실내열교환기(4)가 냉매관(6)을 통해 순차적으로 연설되고, 상기 압축기(1), 실외열교환기(2) 및 실내열교환기(4) 사이에 사방밸브(5)가 설치되어 상기 사방밸브(5)에 의해 압축기(1)에서 토출된 냉매를 실외열교환기(2) 또는 실내열교환기(4)로 순환시켜서 실내에 대해 냉·난방공조를 수행하는 냉·난방 공기조화기에 있어서, 상기 실외열교환기(2)의 공기흐름 방향의 전방에 보조 응축기(10)가 설치되고, 상기 실내열교환기(4)와 보조 응축기(10) 사이의 냉매관로상에 상기 모세관(11)중 냉방용모세관(11a)과 난방운전시에만 냉매가 흐르는 난방용역지밸브(12b)가 병렬로 설치되며, 상기 보조 응축기(10)와 실외열교환기(2) 사이의 냉매관로상에 상기 모세관(11) 중 난방용모세관(11b)과 냉방운전시에만 냉매가 흐르는 냉방용역지밸브(12a)가 병렬로 설치된다.2, the compressor 1, the outdoor heat exchanger 2, the capillary tube 11, and the indoor heat exchanger 4 are sequentially delivered through the refrigerant pipe 6, as shown in FIG. 2. A four-way valve 5 is installed between the compressor 1, the outdoor heat exchanger 2, and the indoor heat exchanger 4, so that the refrigerant discharged from the compressor 1 by the four-way valve 5 is used for the outdoor heat exchanger 2. Or a cooling / heating air conditioner that circulates through the indoor heat exchanger (4) to perform cooling and heating air conditioning for the room, wherein the auxiliary condenser (10) is installed in front of the air flow direction of the outdoor heat exchanger (2). The cooling capillary 11a of the capillary tube 11 and the heating check valve 12b in which the refrigerant flows only during the heating operation are arranged in parallel on the refrigerant line between the indoor heat exchanger 4 and the auxiliary condenser 10. It is installed, the heating capillary (11) of the capillary tube (11) on the refrigerant path between the auxiliary condenser (10) and the outdoor heat exchanger (2) b) and a cooling check valve 12a through which refrigerant flows only in the cooling operation are provided in parallel.
또한, 상기 보조 응축기(10)는 도 4에 나타낸 바와 같이, 실외열교환기(2)와 별도로 형성될 수도 있으며, 도 5에 나타낸 바와 같이, 실외열교환기(2)와 일체로 형성될 수도 있다.In addition, the auxiliary condenser 10 may be formed separately from the outdoor heat exchanger 2 as shown in FIG. 4, or may be integrally formed with the outdoor heat exchanger 2 as shown in FIG. 5.
먼저, 냉방운전시 냉매사이클은 실선의 화살표(→)와 같으며, 압축기(1)에서 토출된 고온 고압의 기체 냉매는 사방밸브(5)를 통해 실외열교환기(2)에서 실외 공기에 의해 냉각되어 응축열을 방출하고, 냉방용역지밸브(12a)를 통해 보조응축기(10)에 유입되어 다시 실외 공기에 의해 냉각되어 응축열을 방출한다. 그리고 상기 실외열교환기(2)와 보조응축기(10)에서 응축열을 방출한 냉매는 냉방용모세관(11a)에서 감압팽창되어 실내열교환기(4)에서 실내 공기의 열을 빼앗아 증발하여 실내 공기를 시원하게 한 다음 사방밸브(5)를 통해 압축기(1)에 흡입된다. 이때, 난방용모세관(11b)과 난방용역지밸브(12b)로는 냉매가 흐르지 않는다.First, during the cooling operation, the refrigerant cycle is the same as the solid arrow (→), and the high temperature and high pressure gas refrigerant discharged from the compressor 1 is cooled by outdoor air in the outdoor heat exchanger 2 through the four-way valve 5. To discharge the condensation heat, flow into the auxiliary condenser 10 through the cooling check valve 12a, and then cool by outdoor air to release the condensation heat. The refrigerant that has released the condensation heat from the outdoor heat exchanger (2) and the auxiliary condenser (10) is expanded under reduced pressure in the cooling capillary (11a) to take the heat of the indoor air from the indoor heat exchanger (4) and evaporate to cool the indoor air. It is then sucked into the compressor 1 through the four-way valve (5). At this time, the refrigerant does not flow into the heating capillary tube 11b and the heating check valve 12b.
본 고안의 냉방운전과 종래의 냉방운전을 비교해 볼 때, 보조응축기(10)가 추가된 본 고안은 실외열교환기(2)에서 응축된 냉매가 다시 보조응축기(10)에서 응축되기 때문에 도 3에서와 같이 냉방효과를 향상시킬 수 있다. 즉, 종래 냉방운전시 냉방사이클은 a→b→c→d로 이루어진다면, 본 고안의 냉방사이클은 a→b→c'→d'로 이루어지기 때문에 b→d'의 폭만큼 냉방효과가 향상된다.When comparing the cooling operation of the present invention and the conventional cooling operation, the present invention to which the auxiliary condenser 10 is added in FIG. 3 because the refrigerant condensed in the outdoor heat exchanger 2 is condensed in the auxiliary condenser 10 again. Like this, the cooling effect can be improved. That is, if the cooling cycle of the conventional cooling operation consists of a → b → c → d, the cooling cycle of the present invention is made from a → b → c '→ d', so that the cooling effect is improved by the width of b → d '. do.
한편, 난방운전시 냉매사이클은 점선의 화살표(→)와 같으며, 압축기(1)에서 토출된 고온 고압의 기체 냉매는 사방밸브(5)를 통해 실내열교환기(4)에서 실내 공기에 의해 냉각되어 응축열을 방출하여 실내 공기를 따뜻하게 하고, 난방용역지역밸브(12b)를 통해 보조 응축기(10)에 유입되어 다시 실외 공기에 의해 냉각되어 응축열을 방출한 다음 난방용모세관(11b)에서 감압팽창되어 실외열교환기(2)에서 실외 공기의 열을 빼앗아 증발하여 실외 공기를 낮춘 다음 사방밸브(5)를 통해 압축기(1)에 흡입된다. 이때, 냉방용역지역밸브(12a)와 냉방용모세관(11a)으로는 냉매가 흐르지 않는다.On the other hand, during the heating operation, the refrigerant cycle is the same as the dotted arrow (→), and the high temperature and high pressure gas refrigerant discharged from the compressor 1 is cooled by indoor air in the indoor heat exchanger 4 through the four-way valve 5. To discharge the condensation heat to warm the indoor air, enter the auxiliary condenser 10 through the heating service region valve 12b, cool down by outdoor air again to release the condensation heat, and expand under reduced pressure in the heating capillary tube 11b The heat from the heat exchanger (2) takes the heat of the outdoor air and evaporates to lower the outdoor air and is then sucked into the compressor (1) through the four-way valve (5). At this time, the refrigerant does not flow into the cooling service region valve 12a and the cooling capillary tube 11a.
상기 난방운전시 실외 공기는 먼저 실외열교환기(2)의 공기흐름 방향의 전방에 위치한 보조응축기(10)와 열교환되어 온도가 어느 정도 상승된 상태에서 실외열교환기(2)에 공급되어 다시 실외열교환기(2)와 열교환된다. 즉, 보조응축기(10)에 의해 온도가 상승된 실외 공기가 실외열교환기(2)와 열교환되므로 실외열교환기(2)의 냉매증발온도가 상승되며 실외열교환기(2) 표면에 발생한 응축수가 결빙되는 것(착상)을 감소시킨다.In the heating operation, the outdoor air is first heat-exchanged with the auxiliary condenser 10 located in the front of the air flow direction of the outdoor heat exchanger 2, and is supplied to the outdoor heat exchanger 2 in a state where the temperature is raised to some extent, and then again the outdoor heat exchange. Heat exchange with group (2). That is, since the outdoor air whose temperature is increased by the auxiliary condenser 10 is heat-exchanged with the outdoor heat exchanger 2, the refrigerant evaporation temperature of the outdoor heat exchanger 2 is increased, and condensed water generated on the surface of the outdoor heat exchanger 2 freezes. Reduce the appearance (implantation).
이에 따라, 난방운전중 제상운전의 빈도가 줄어들어 실외열교환기(2)의 열교환 효율이 향상되고 제상운전중 실내에 따뜻한 공기가 공급되지 못함으로 인한 불쾌감을 감소시킬 수 있으며, 실외 온도가 낮은 지역에서도 난방기기로 사용이 가능하다.Accordingly, the frequency of the defrosting operation during the heating operation is reduced, thereby improving heat exchange efficiency of the outdoor heat exchanger 2 and reducing the discomfort due to the inability to supply warm air to the indoors during the defrosting operation. It can be used as a heating device.
그리고 실외열교환기(2)에서 냉매의 증발온도가 상승되므로, 실내열교환기(4)에서 냉매의 응축온도를 다소 상승시켜서 난방능력이 저하되지는 않는다.In addition, since the evaporation temperature of the refrigerant is increased in the outdoor heat exchanger (2), the condensation temperature of the refrigerant is slightly increased in the indoor heat exchanger (4) so that the heating capacity is not lowered.
또한, 상기 보조응축기(10)는 도 4와 같이, 실외열교환기(2)와 분리되어 설치될 수 있으며, 도 5와 같이 실외열교환기(2)와 일체로 형성될 수도 있으며, 어느 것이나 공기흐름 방향의 전방에 보조응축기(10)가 설치되고 그 뒤에 실외열교환기(2)가 설치된다.In addition, the auxiliary condenser 10 may be installed separately from the outdoor heat exchanger 2, as shown in FIG. 4, may be formed integrally with the outdoor heat exchanger 2, as shown in FIG. Auxiliary condenser 10 is installed in front of the direction, followed by an outdoor heat exchanger 2.
도 5와 같이, 보조응축기(10)가 실외열교환기(2)와 일체로 형성된 경우, 공기흐름 방향의 첫 번째 부분(A)은 보조응축기(10)가 되고 두 번째 부분(B)이 실외열교환기(2)가 되며, 보조응축기(10)와 실외열교환기(2)가 핀을 통한 열전달이 가능하여 보조응축기(10)와 실외열교환기(2)가 분리되어 있는 경우 보다 효율이 더욱 좋다.As shown in FIG. 5, when the auxiliary condenser 10 is integrally formed with the outdoor heat exchanger 2, the first part A of the air flow direction becomes the auxiliary condenser 10 and the second part B is the outdoor heat exchanger. And the subcondenser 10 and the outdoor heat exchanger 2 are capable of heat transfer through the fins, so that the efficiency of the auxiliary condenser 10 and the outdoor heat exchanger 2 is better.
본 발명 보조 응축기를 구비한 냉·난방 겸용 공기조화기는 냉·난방 겸용 공기조화기에 있어서, 실외열교환기의 공기흐름 방향 전방에 보조 응축기를 설치하여 난방운전시 실외열교환기에 유입되는 실외 공기의 온도를 상승시켜서 실외열교환기와의 열교환시키는 것으로, 실외열교환기의 서리 발생을 줄여 난방효율을 향상시켜서 실외 온도가 낮은 지역에서도 사용할 수 있도록 한 유용한 것이다.The air conditioner for dual cooling and heating provided with the present invention condenser includes an auxiliary condenser in front of the air flow direction of the outdoor heat exchanger in order to adjust the temperature of the outdoor air flowing into the outdoor heat exchanger during the heating operation. By increasing the heat exchange with the outdoor heat exchanger, it is useful to reduce the occurrence of frost of the outdoor heat exchanger to improve the heating efficiency, so that it can be used even in areas where the outdoor temperature is low.
