일반적으로 일의 능률을 올리도록 온도와 습도를 일정하게 유지하는 것을 공기 조화라 하며, 이때 사용되는 인위적인 수단 및 장치를 공기조화장치라 한다.In general, maintaining a constant temperature and humidity to improve work efficiency is called air conditioning, and the artificial means and apparatus used at this time is called an air conditioner.

에어콘은 압축된 팽창되면서 발생하는 감열작용을 이용하여 흡입된 공기를 냉각시키고, 냉각된 공기를 실내로 토출시켜 냉방하도록 한 것이다.The air conditioner cools the sucked air by using the thermal effect generated by the compressed expansion, and discharges the cooled air into the room to cool it.

도 1은 일반적인 패키지 에어콘의 내부 구조를 도시한 단면도로서, 미도시한 실외기에 설치된 응축열교환기로부터 액체 상태로 냉각된 냉매가 파이프라인을 통해 유입되고, 유입된 냉매가 팽창 밸브를 통해 온도가 낮아진 상태로 증발열교환기 내를 통과하면서 주위 공기를 냉각시킨다. 이 냉각된 공기를 실내로 토출시키는 실내기를 도시하고 있다.1 is a cross-sectional view showing the internal structure of a general package air conditioner, a refrigerant cooled in a liquid state is introduced through a pipeline from a condensation heat exchanger installed in an outdoor unit (not shown), and the temperature of the introduced refrigerant is lowered through an expansion valve. The ambient air is cooled by passing through the evaporative heat exchanger. The indoor unit which discharges this cooled air to the room is shown.

실내기의 전체적인 구성은 리어 케이스(10)와 전면 커버(20)로 구비된 캐비닛(30)과, 캐비닛(30)내부 중앙에 팽창 밸브(미도시함)와 연결된 증발열교환기(40) 및 블로워(50)등으로 구비되어 있다.The overall configuration of the indoor unit is a cabinet 30 provided with a rear case 10 and a front cover 20, an evaporation heat exchanger 40 and a blower 50 connected to an expansion valve (not shown) in the center of the cabinet 30. And so on.

여기에서, 전면 커버(20)의 상단에 수평 루버(22a)로 구비된 토출그릴(22)과, 토출그릴(22)과 대향되는 하단에 흡입그릴(24)이 설치된다.Here, the discharge grill 22 provided with the horizontal louver 22a at the upper end of the front cover 20, and the suction grill 24 is provided at the lower end opposite to the discharge grill 22.

증발열교환기(40)는 열교환 과정에서 발생되는 응축수가 하부로 흘러 모이도록 경사지게 설치되어 있고, 그 하부는 응축수 배출팬(42)이 고정되어 있다.The evaporation heat exchanger 40 is installed to be inclined so that condensate generated in the heat exchange process flows to the lower part, and the condensate discharge fan 42 is fixed to the lower part.

이와 같이 구성된 실내기는 토출그릴(22)의 하부에 구비된 미도시한 컨트롤부를 조작하여 전원을 인가하게 되면 실외기 내에 설치되어 있는 압축기가 가동된다. 압축기의 가동으로 액체 상태의 냉매는 압축된 상태(고온, 고압)로 응축열교환기로 이동하게 되고, 응축열교환기 내를 흐르면서 열교환 된다. 액체 상태로 변환된 냉매는 파이프라인을 통해 팽창 밸브내를 통과하면서 유로 저항에 의해 저온, 저압으로 변환된다.The indoor unit configured as described above operates a control unit not shown in the lower part of the discharge grill 22 to apply power to the compressor installed in the outdoor unit. As the compressor operates, the liquid refrigerant moves to the condensation heat exchanger in a compressed state (high temperature and high pressure), and heat exchanges through the condensation heat exchanger. The refrigerant converted into the liquid state is converted into low temperature and low pressure by the flow path resistance while passing through the expansion valve through the pipeline.

저온, 저압의 냉매는 증발열교환기를 통과하면서 주위 공기를 냉각시키게 되고, 냉각된 공기는 블로워(50)의 구동에 의해 발생되는 토출력으로 토출그릴(22)을 통해 실내로 배출됨으로써, 냉방을 하게 된다.The low-temperature and low-pressure refrigerant cools the surrounding air while passing through the evaporative heat exchanger, and the cooled air is discharged to the room through the discharge grill 22 with the output of the earth generated by the drive of the blower 50, thereby cooling the air. do.

이하, 본 고안의 일실시예를 첨부 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 패키지 에어콘의 내부 구조를 도시한 단면도로서, 종래 구성과 동일한 구성에 대해서는 동일 부호를 사용한다.Figure 2 is a cross-sectional view showing the internal structure of the package air conditioner according to the present invention, the same reference numerals are used for the same configuration as the conventional configuration.

먼저, 본 실시예를 설명함에 앞서 종래와 연계하여 설명하면, 도 1에 도시된 바와 같이, 실내기는 캐비닛(30) 내부 중앙에 증발열교환기(40) 및 블로워(50)등으로 구비되어 있고, 그 전면에 토출그릴(22)과 대향되도록 흡입그릴(24)이 설치된 전면 커버(20)로 이루어진다. 또한, 열교환 과정에서 발생되는 응축수를 배출하도록 응축수 배출팬(42)이 설치되어 있다.First, prior to the present embodiment will be described in connection with the prior art, as shown in Figure 1, the indoor unit is provided with an evaporation heat exchanger 40, a blower 50, etc. in the center of the cabinet 30, The front cover 20 is provided with a suction grill 24 installed to face the discharge grill 22 on the front surface. In addition, the condensate discharge fan 42 is installed to discharge the condensate generated in the heat exchange process.

이와 같은 구성으로 이루어진 실내기에 있어서, 전원이 실, 내외기에 인가되면, 압축기로부터 압축된 가스가 응축열교환기를 거쳐 냉각된 상태로 팽창밸브를 통과하게 되고, 팽창밸브를 통과하면서 온도가 낮아진 상태로 증발열교환기를 통과하면서 주위 공기를 냉각시키게 된다.In the indoor unit having such a configuration, when power is applied to the room and the outside, the compressed gas from the compressor passes through the expansion valve in a cooled state through the condensation heat exchanger, and the evaporative heat is lowered while passing through the expansion valve. As it passes through the exchanger it cools the ambient air.

이때, 실내기에 내설된 블로워(50)의 구동으로 실내 공기는 흡입그릴(24)을 통해 캐비닛(30)내로 유입되고, 증발열교환기(40)를 거쳐 냉각된 상태로 토출그릴(22)을 경유하여 실내로 토출시킴으로써, 실내를 냉방시키게 된다.At this time, the indoor air is driven into the cabinet 30 through the suction grill 24 and driven through the discharge grill 22 in a cooled state through the evaporation heat exchanger 40 by driving the blower 50 installed in the indoor unit. By discharging to the room, the room is cooled.

이와 같이 블로워(50)의 구동에 의한 흡입력으로 실내 공기가 흡입그릴(24)을 통해 캐비닛(30)내로 유입되고, 유입된 공기가 증발열교환기(40)를 통해 냉각되는 과정에서 증발열교환기(40)의 하부로 유입되는 공기량이 적어져 열교환율이 낮아지는 것을 방지하도록 본 발명에서 흡입그릴(24)과 증발열교환기(40)의 하부에 공기공급보조수단(60)을 설치하였다. 이 공기공급보조수단(60)은 캐비닛(30)의 하단과 증발열교환기(40)의 하부에 회전 가능하게 설치된 크로스 팬(66)과, 이 크로스 팬(66)의 양측에 설치된 제 1,2가이더(62,64)로 이루어진다.As described above, the indoor air is introduced into the cabinet 30 through the suction grill 24 by the suction force driven by the blower 50, and the evaporated heat exchanger 40 is cooled in the process of cooling the introduced air through the evaporative heat exchanger 40. In order to prevent the amount of air flowing into the lower portion of the lower heat exchange rate in the present invention, the air supply auxiliary means 60 is installed in the lower portion of the suction grill 24 and the evaporation heat exchanger 40. The air supply assistance means (60) includes a cross fan (66) rotatably installed at a lower end of the cabinet (30) and a lower part of the evaporative heat exchanger (40), and first and second guiders provided at both sides of the cross fan (66). (62,64).

여기에서, 크로스 팬(66)은 블로워(50)와 연동 되도록 설치한다. 제 1가이더(62)는 증발열교환기(40) 하단에 설치된 배출팬(42)의 일측과 캐비닛(30) 하단 사이에 고정하는 것이 바람직하며, 크로스 팬(66)과 근접한 곳은 만곡형의 홈을 형성하여 증발열교환기(40) 하단으로 토출되도록 하는 것이 더욱 바람직하다.Here, the cross fan 66 is installed to interlock with the blower 50. The first guider 62 is preferably fixed between one side of the discharge fan 42 installed at the bottom of the evaporation heat exchanger 40 and the bottom of the cabinet 30, and the groove close to the cross fan 66 has a curved groove. It is more preferable to form and discharge to the bottom of the evaporation heat exchanger (40).

제 2가이더(64)는 제 1가이더(62)의 상부면에 그 하단이 위치되도록 설치하고, 크로스 팬(66)에 의해 토출되는 공기가 흡입그릴(24)의 하부를 통해 역류되는 것을 방지하도록 소정 길이를 가지는 만곡형태로 설치하는 것이 바람직하다.The second guider 64 is installed on the upper surface of the first guider 62 so that the lower end thereof is positioned, and the air discharged by the cross fan 66 is prevented from flowing back through the lower portion of the suction grill 24. It is preferable to install in a curved form having a predetermined length.

이와 같이, 실내기가 가동되면 캐비닛에 내설된 블로워(50)가 구동함으로써, 실내 공기는 흡입그릴(24)을 통해 내부로 유입되고, 동시에 크로스 팬(66)의 구동으로 흡입그릴(24) 하부에서 실내 공기를 흡입한다. 이 실내 공기는 크로스 팬(66)을 지나 제 1가이더(62) 상단에 형성된 만곡형 홈에 안내되고, 증발열교환기(40)의 하단을 경유한다.As such, when the indoor unit is operated, the blower 50 installed in the cabinet is driven, so that the indoor air is introduced into the interior through the suction grill 24, and at the same time, the lower portion of the suction grill 24 is driven by the cross fan 66. Inhale indoor air. This indoor air is guided to the curved groove formed in the upper end of the first guide 62 through the cross fan 66, and passes through the lower end of the evaporation heat exchanger (40).

이때, 제 1가이더(62)의 만곡형 홈으로 안내된 흡입된 공기는 가속력에 의해 흡입그릴(24)의 뒷면을 통해 실내로 역류하려 하나 제 2가이더(64)의 상단부가 높게 설치되어 있어 이를 방지하게 된다.At this time, the suctioned air guided to the curved groove of the first guider 62 tries to flow back to the room through the rear surface of the suction grill 24 by the acceleration force, but the upper end of the second guider 64 is installed high. Will be prevented.

따라서, 캐비닛(30)의 전면 하부에 구비된 흡입그릴(24)을 통해 실내 공기가 흡입되는 가운데 그 하부에 설치된 크로스 팬에 의해 국부적으로 강한 실내 공기가 유입됨으로써, 증발열교환기(40)의 전면적을 사용하게 된다.Therefore, while the indoor air is sucked in through the suction grille 24 provided in the lower part of the cabinet 30, locally strong indoor air is introduced by the cross fan installed at the lower part thereof, thereby reducing the entire area of the evaporation heat exchanger 40. Will be used.

이상에서 살펴 본 바와 같이, 본 발명은 흡입그릴과 증발열교환기의 사이에 블로워와 연동되는 크로스 팬을 설치하여 많은 량의 실내 공기가 증발열교환기를 통과되도록 함으로써, 그 열교환율을 향상시키고, 냉방효율을 증가시킨 이점이 있다.As described above, in the present invention, a cross fan interlocked with a blower is installed between the suction grill and the evaporative heat exchanger to allow a large amount of indoor air to pass through the evaporative heat exchanger, thereby improving the heat exchange rate and cooling efficiency. There is an increased advantage.
