이에 도시한 바와 같이, 종래의 창문형 에어컨은 소정의 내부공간을 갖도록 형성하는 케이싱(10)과, 케이싱(10)내 일측에 설치하여 실외 공기로 열교환하는 실외측 열교환부(20)와, 케이싱(10)내 타측에 설치하여 실내 공기를 열교환하는 실내측 열교환부(30)로 구성한다.As shown in the drawing, a conventional window air conditioner has a casing 10 formed to have a predetermined internal space, an outdoor side heat exchanger 20 installed at one side of the casing 10 to heat-exchange with outdoor air, and a casing ( 10) is installed on the other side in the interior heat exchanger 30 to heat the indoor air.
케이싱(10)은 실외측의 양 측면에 실외측 공기흡입구(11)를 형성하고, 실외측의 전방면에 실외측 공기토출구(12)를 형성하고 있다.The casing 10 forms the outdoor air intakes 11 on both sides of the outdoor side, and the outdoor air discharge ports 12 on the front side of the outdoor side.
또, 케이싱(10)은 실내측의 전방면에 실내측 공기흡입구(13)를 형성하고, 실내측의 전방면 상반부, 즉 실내측 공기흡입구(13)의 상측에 실내측 공기토출구(14)를 형성하고 있다.In addition, the casing 10 forms an indoor air inlet 13 on the front face of the interior side, and an indoor air outlet 14 on the upper half of the front side of the interior, that is, above the indoor air inlet 13. Forming.
실외측 열교환부(20)는 압축기(21)와, 이 압축기(21)에 냉매관으로 연결하여 실외공기와 열교환하면서 가스냉매를 액냉매로 변환하는 응축용 열교환기(22)와, 응축용 열교환기(22)의 안쪽에 설치하여 실외의 공기를 흡입하여 상기 응축용 열교환기(22)쪽으로 토출하는 축류팬(axial fan)으로 된 실외팬(23)으로 이루어져 있다.The outdoor side heat exchanger 20 is a compressor 21, a condensation heat exchanger 22 that converts the gas refrigerant into a liquid refrigerant while exchanging heat with the outdoor air by connecting the compressor 21 with a refrigerant pipe, and a heat exchanger for condensation. It is composed of an outdoor fan (23) made of an axial fan installed inside the machine (22) to suck the outdoor air and discharge it toward the condensation heat exchanger (22).
실내측 열교환부(30)는 실외측 열교환부(20)의 응축용 열교환기(22)와 연결하여 액냉매를 저온저압의 가스냉매로 다시 변환하는 증발용 열교환기(31)와, 증발용 열교환기(31)의 안쪽에 설치하여 실내의 공기를 흡입하여 상기 증발용 열교환기(31)쪽으로 토출하는 원심팬(centrifugal fan)으로 된 실내팬(32)으로 이루어져 있다.The indoor heat exchanger 30 is connected to the heat exchanger 22 for condensation of the outdoor heat exchanger 20 to convert the liquid refrigerant into a low-temperature low-pressure gas refrigerant, and an evaporation heat exchanger 31. The inner fan 32 is formed of a centrifugal fan installed inside the machine 31 to suck air in the room and discharge the air to the evaporation heat exchanger 31.
증발용 열교환기(31)와 실내팬(32) 사이에는 실내 공기를 실내팬(32)으로 안내하는 실내측 오리피스(33)를 설치하고, 실내팬(32)의 상측에는 그 실내팬(32)을 통과하는 실내 공기를 실내측 공기토출구(14)로 안내하는 실내측 공기안내판(34)을 설치하고 있다.An indoor orifice 33 for guiding indoor air to the indoor fan 32 is provided between the evaporation heat exchanger 31 and the indoor fan 32, and the indoor fan 32 is disposed above the indoor fan 32. An indoor air guide plate 34 for guiding indoor air passing through the indoor air discharge port 14 is provided.
한편, 실외측 열교환부(20)와 실내측 열교환부(30)의 사이에는 케이싱(10) 내부를 실외측과 실내측으로 구획하는 격판(15)을 설치하고, 격판(15)에는 상기한 실외팬(23)과 실내팬(32)에 각각 결합하여 회전력을 전달하는 팬모터(40)를 설치하고 있다.On the other hand, between the outdoor heat exchanger 20 and the indoor heat exchanger 30 is provided a diaphragm 15 for dividing the inside of the casing 10 into an outdoor side and an indoor side, and the diaphragm 15 is the outdoor fan described above. The fan motor 40 is coupled to the 23 and the indoor fan 32 to transmit rotational force, respectively.
도면중 미설명 부호인 24는 실외측 쉬라우드, 25는 실외측 오리피스이다.In the drawings, reference numeral 24 denotes an outdoor side shroud and 25 an outdoor side orifice.
상기와 같은 종래 창문형 에어컨은 다음과 같이 작동한다.The conventional window air conditioner as described above operates as follows.
즉, 에어컨에 전원을 인가하면 압축기(21)가 구동하여 냉매를 순환함과 아울러 팬모터(40)가 구동하여 실외의 공기와 실내의 공기를 실외측과 실내측으로 각각 흡입하여 각각의 열교환기(22)(31)와 열교환한 후 토출시키게 된다.That is, when power is supplied to the air conditioner, the compressor 21 is driven to circulate the refrigerant, and the fan motor 40 is driven to suck outdoor air and indoor air to the outdoor side and the indoor side, respectively. 22) and heat is exchanged with (31) to discharge.
이를 보다 상세히 살펴보면 다음과 같다.Looking at this in more detail as follows.
도 2에서와 같이 실외측에는 실외팬(23)으로 축류팬을 설치함에 따라 케이싱(10)의 실외측 양 측면에 구비한 실외측 공기흡입구(11)(11)를 통해 실외 공기를 흡입하였다가 실내를 기준으로 후방면, 즉 실외를 향해 전방으로 구비한 실외측 공기토출구(12)를 통해 실외로 다시 배출한다. 이때 실외 공기는 실외측 열교환기인 응축용 열교환기(22)와 접촉하여 열교환기 내부의 냉매를 응축시키면서 더운 공기가 되어 배출된다.As shown in FIG. 2, the outdoor air is sucked through the outdoor air inlets 11 and 11 provided at both sides of the casing 10 as the axial fan is installed at the outdoor side. With respect to the rear surface, that is to discharge again to the outdoor through the outdoor air discharge port 12 provided forward toward the outdoor. At this time, the outdoor air comes into contact with the heat exchanger 22 for condensation, which is an outdoor heat exchanger, and is discharged as hot air while condensing the refrigerant inside the heat exchanger.
반면, 실내측에는 실내팬(32)으로 원심팬을 설치함에 따라 케이싱(10)의 전방측 하반부에 구비한 실내측 공기흡입구(13)를 통해 실내 공기를 흡입하였다가 케이싱(10)의 전방측 상반부에 수직하게 구비한 실내측 공기토출구(14)를 통해 실내로 다시 배출한다. 이때 실내 공기는 실내측 열교환기인 증발용 열교환기(31)와 접촉하여 열교환기 내부의 냉매를 증발시키면서 찬 공기가 되어 실내로 배출되는 것이었다.On the other hand, as the centrifugal fan is installed as the indoor fan 32 on the indoor side, the indoor air is sucked through the indoor air suction opening 13 provided in the lower half of the casing 10, and the upper upper half of the casing 10 is provided. It is discharged back to the room through the indoor air discharge port 14 provided perpendicular to the. At this time, the indoor air was in contact with the evaporation heat exchanger 31, which is an indoor heat exchanger, and discharged into the room as cold air while evaporating the refrigerant inside the heat exchanger.
그러나, 상기와 같은 종래 창문형 에어컨에 있어서는, 실외측 공기흡입구(13)를 측면에 형성하는 반면 공기토출구(14)는 상기 공기흡입구(13)와 수직한 전방면(실외를 기준으로)에 형성하여 유로저항이 증가함에도 불구하고 종래에는 실외팬으로 풍량은 크나 유로저항에 불리한 축류팬을 사용함에 따라 유로저항을 줄이기 위하여는 비교적 넓은 흡입공간을 확보하도록 케이싱의 길이를 확대하여야 할 뿐만 아니라 외부의 온도가 높아질수록 응축용 열교환기(22)의 성능이 저하되는 문제점이 있었다.However, in the conventional window type air conditioner as described above, the outdoor air inlet 13 is formed on the side while the air outlet 14 is formed on the front surface (relative to the outside) perpendicular to the air inlet 13. In spite of the increase in flow resistance, conventional airflow is large with outdoor fan. However, in order to reduce flow resistance, casing length must be expanded to secure relatively wide suction space, and external temperature is used to reduce flow resistance.

상기와 같은 본 발명 창문형 에어컨은 다음과 같은 작용 효과가 있다.The window air conditioner of the present invention as described above has the following effects.
즉, 에어컨에 전원을 인가하면 압축기(121)가 구동하여 냉매를 응축용 열교환기(122)와 증발용 열교환기(131)로 순환시킴과 아울러 팬모터(140)가 함께 구동하여 실외 공기와 실내 공기를 각각 케이싱(110)의 실외측과 실내측으로 흡입한 후 실외 공기는 실외측 열교환기인 응축용 열교환기(122)와, 실내 공기는 실내측 열교환기인 증발용 열교환기(131)와 각각 열교환하면서 각 열교환기(122)(131)의 냉매를 상변화시키고 이 과정에서 실외 공기는 더운 공기로, 실내 공기는 찬공기로 각각 실외와 실내로 토출된다.That is, when power is supplied to the air conditioner, the compressor 121 is driven to circulate the refrigerant to the condensation heat exchanger 122 and the evaporation heat exchanger 131, and the fan motor 140 is driven together to provide outdoor air and indoors. After each air is sucked to the outdoor side and the indoor side of the casing 110, the outdoor air is heat-exchanged with the condensation heat exchanger 122 which is an outdoor heat exchanger, and the indoor air is respectively exchanged with the evaporation heat exchanger 131 which is an indoor heat exchanger. The refrigerant of each heat exchanger (122) (131) is phase-changed, and in this process, outdoor air is hot air, and indoor air is discharged to cold air and outdoor.
여기서, 실내측에서는 실내팬(132)으로 원심팬을 설치함에 따라 케이싱(110)의 전방측 하반부에 구비한 실내측 공기흡입구(113)를 통해 실내 공기가 전방에서 흡입되었다가 케이싱(110)의 전방측 상반부에 구비한 실내측 공기토출구(114)를 통해 실내로 다시 배출되는 반면, 실외측에서는 실외팬(123)으로 실내팬(132)과 같이 원심팬을 설치함에 따라 케이싱(110)의 양 측면에 구비한 실외측 공기흡입구(111)를 통해 실외 공기가 케이싱(110)의 측면에서 흡입되었다가 케이싱(110)의 실외측 전방에 구비한 실외측 공기토출구(112)를 통해 실외로 다시 배출된다.Here, in the indoor side, the indoor air is sucked from the front through the indoor air inlet 113 provided in the lower half of the casing 110 as the centrifugal fan is installed as the indoor fan 132, and then the front of the casing 110. While it is discharged back to the room through the indoor air discharge port 114 provided in the upper half of the side, on the both sides of the casing 110 by installing a centrifugal fan such as the indoor fan 132 as the outdoor fan 123 in the outdoor side. The outdoor air is sucked from the side of the casing 110 through the outdoor side air inlet 111 provided and then discharged back to the outside through the outdoor air outlet 112 provided in front of the outdoor side of the casing 110.
이때, 실내측 열교환부(130)에 구비한 증발용 열교환기(131)의 외표면에는 냉동사이클장치의 운전시 성에가 발생하고, 이 성에는 제상운전을 하는 동안 녹아 케이싱(110)의 실내측 바닥으로 흘렀다가 위상차에 의해 케이싱(110)의 실외측 바닥으로 고인다. 이 응축수는 실외팬(123)인 원심팬의 회전시 함께 회전하는 비산링(123d)에 의해 퍼 올려져 응축용 열교환기(122)의 표면에 뿌려진다. 이 응축용 열교환기(122)에 뿌려진 응축수는 열교환기 내부의 냉매 보다 상대적으로 낮은 온도를 유지함에 따라 냉매가 보다 빠르게 열을 방출하면서 응축될 수 있도록 한다.At this time, frost occurs during operation of the refrigeration cycle apparatus on the outer surface of the evaporative heat exchanger 131 provided in the indoor heat exchanger 130, and this castle melts during defrosting operation and the indoor side of the casing 110 is operated. It flowed to the floor and accumulated by the phase difference to the outdoor floor of the casing 110. The condensed water is sprinkled by the scattering ring 123d which rotates together with the rotation of the centrifugal fan, which is the outdoor fan 123, and is sprayed on the surface of the heat exchanger 122 for condensation. The condensed water sprayed on the condensation heat exchanger 122 maintains a relatively lower temperature than the refrigerant inside the heat exchanger, thereby allowing the refrigerant to be condensed while releasing heat more quickly.
또, 원심팬의 경우 축류팬에 비해 유로저항에 대한 영향을 덜 받는 특성을 감안하면 에어컨을 소형화할 때 응축용 열교환기(122)와 격판(115) 사이의 간격이 좁아지면서 유로저항이 증가하더라도 실외 공기의 풍량이 급격하게 감소하는 것을 방지하여 에어컨을 소형화하더라도 성능을 최대한 유지할 수 있다.In addition, in the case of the centrifugal fan, when considering the characteristics that are less affected by the flow resistance than the axial flow fan, even if the flow resistance increases as the gap between the heat exchanger 122 and the diaphragm 115 becomes smaller when the air conditioner is miniaturized By preventing a sudden decrease in the air volume of the outdoor air, even if the air conditioner is miniaturized, the performance can be maintained to the maximum.
본 발명에 의한 원심팬은, 실내측은 물론 실외측에 원심팬을 설치함으로써, 에어컨을 소형화함에 따른 실외측의 유로저항이 증가하더라도 실외측 풍량의 저하를 미연에 방지하여 에어컨 효율을 유지할 수 있다.In the centrifugal fan according to the present invention, by installing the centrifugal fan in the indoor side as well as the outdoor side, the air conditioner efficiency can be maintained by preventing the decrease in the outdoor air volume even if the flow path resistance of the outdoor side increases due to the miniaturization of the air conditioner.
또, 실외측 원심팬에는 비산링을 형성하여 응축수를 응축용 열교환기로 퍼 올려 냉매의 응축효과를 높임으로써 에어컨의 성능을 더욱 높일 수 있다.In addition, by forming a scattering ring in the outdoor side centrifugal fan to spread the condensed water to the condensation heat exchanger to increase the condensation effect of the refrigerant can further improve the performance of the air conditioner.
