본 발명은 공기조화기 실외기에 관한 것으로서, 더욱 상세하게는 공기조화기 실외기에 구비되는 압축기가 발생시키는 소음을 저감하기 위한 공기조화기 실외기의 소음 저감구조에 관한 것이다.The present invention relates to an air conditioner outdoor unit, and more particularly, to a noise reduction structure of an air conditioner outdoor unit for reducing noise generated by a compressor provided to the air conditioner outdoor unit.
일반적으로 공기조화기는 실내를 냉난방시키기 위해 사용되는 장치로서, 크게 실내에 설치되어 냉매의 팽창 및 증발작용이 수행되는 실내기와 실외에 설치되어 냉매의 압축 및 응축작용이 수행되는 실외기로 구성된다.In general, an air conditioner is a device used to cool and heat a room. The air conditioner is generally composed of an indoor unit installed in a room and performing expansion and evaporation of the refrigerant and an outdoor unit installed in the outdoor and performing compression and condensation of the refrigerant.
도 1 은 종래의 공기조화기 실외기를 나타내는 분해 사시도이다.1 is an exploded perspective view showing a conventional air conditioner outdoor unit.
도시한 바와 같이 종래 공기조화기 실외기는 전면패널(11), 후면패널(12), 베이스패널(13)이 케이싱(10)을 이루고, 상기 전면패널(11)과 후면패널(12) 사이에 팬(21), 모터(22), 열교환기(30)가 차례로 설치되며, 차음벽(40)에 의해 구획된 상기 베이스패널(13) 타측에 압축기(51)와 어큐물레이터(52)가 설치된다.As shown, a conventional air conditioner outdoor unit includes a front panel 11, a rear panel 12, and a base panel 13 forming a casing 10, and a fan between the front panel 11 and the rear panel 12. 21, the motor 22, and the heat exchanger 30 are sequentially installed, and the compressor 51 and the accumulator 52 are installed at the other side of the base panel 13 partitioned by the sound insulation wall 40.
이와 같이 구성된 종래 공기조화기 실외기는 상기 압축기(51)에 의해 압축된 냉매가 상기 열교환기(30)로 보내지며, 상기 팬(21)의 회전에 의해 흡입된 외부공기가 냉매와 열교환을 하게 되고, 열교환된 냉매는 실내기로 보내지며, 공기는 케이싱의 전면패널(11)를 통해 외부로 토출된다.In the conventional air conditioner outdoor unit configured as described above, the refrigerant compressed by the compressor (51) is sent to the heat exchanger (30), and the external air sucked by the rotation of the fan (21) exchanges heat with the refrigerant. The heat exchanged refrigerant is sent to the indoor unit, and the air is discharged to the outside through the front panel 11 of the casing.
그런데, 공기조화기 실외기는 압축기(51)가 냉매를 압축하면서 큰 소음이 발생시키게 되고, 이와 같이 발생된 소음은 실외기 외부로 방사되어 제품의 품질에나쁜 영향을 미친다.However, the outdoor unit of the air conditioner generates a large noise while the compressor 51 compresses the refrigerant, and the generated noise is radiated to the outside of the outdoor unit to adversely affect the quality of the product.
이에 따라, 상기 압축기(51)의 소음을 흡수하여 실외기의 소음을 저감하기 위한 여러가지 방법이 시도되었고, 그 중에서 압축기(51) 주위 공간에 흡음재, 차음재 또는 흡차음재를 설치함으로써 상기 압축기(51)의 소음을 흡수하여 실외기의 소음을 저감하고자 하는 발명이 개시되어 왔다.Accordingly, various methods for reducing the noise of the outdoor unit by absorbing the noise of the compressor 51 have been attempted, and among them, a sound absorbing material, a sound insulating material, or a sound absorbing and insulating material is provided in a space around the compressor 51. The invention to reduce the noise of the outdoor unit by absorbing the noise has been disclosed.
하지만, 전술한 바와 같이 실외기의 주 소음원인 압축기의 소음을 흡수하기 위해 흡음재등을 설치함에 있어서, 압축기(51)의 소음 방사 특성에는 무관하게 상기 압축기(51) 주위 공간에 흡음재를 설치하는데 불과했다.However, as described above, in the case of installing the sound absorbing material to absorb the noise of the compressor which is the main noise source of the outdoor unit, the sound absorbing material was merely installed in the space around the compressor 51 irrespective of the noise radiation characteristics of the compressor 51. .
따라서, 압축기(51)의 소음을 효과적으로 차단하지 못했으며, 또한 불필요한 흡차음재, 흡음재를 사용하는 문제점이 있었다.Therefore, the noise of the compressor 51 could not be effectively blocked, and there was a problem of using unnecessary sound absorbing and insulating materials and sound absorbing materials.
본 발명은 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 공기조화기 실외기의 주소음원인 압축기에서 발생하는 소음을 보다 효과적으로 흡수하여 흡차음재 및 흡음재의 사용은 최소화하고 공기조화기 실외기 소음의 저감은 최대화하는데 그 목적이 있다.The present invention has been made to solve the above problems, and more effectively absorbs the noise from the compressor which is the address sound source of the air conditioner outdoor unit to minimize the use of sound absorbing and sound absorbing material and sound absorbing material and to maximize the reduction of the air conditioner outdoor unit noise Its purpose is to.

As a concentrated radiation.
따라서, 이와 같이 방사된 소음은 일차적으로 압축기(151)와 어큐물레이터(152)의 둘레를 감싼 흡차음재(161)에 의해 흡수 차단되고, 상기 흡차음재(161)를 통과한 소음은 다시 상기 전면패널(111)과 후면패널(112)에 설치된 흡음재(162)에 의해 흡수된다.Therefore, the radiated noise is absorbed and blocked primarily by the sound absorbing and insulating material 161 wrapped around the compressor 151 and the accumulator 152, and the noise passing through the sound absorbing and insulating material 161 is again the front surface. Absorbed by the sound absorbing material 162 provided on the panel 111 and the rear panel 112.
즉, 본 발명은 압축기의 소음 방사 특성을 이용하여 압축기(151)의 소음을 전면패널(111)과 후면패널(112)에 대략 수직방향으로 방사되도록 유도하고, 상기 전면패널(111)과 후면패널(112)에 흡음재(162)를 설치함으로써, 압축기(151)의 소음을 효과적으로 흡수 저감하도록 한 것이다.That is, the present invention induces the noise of the compressor 151 to be radiated in a substantially vertical direction to the front panel 111 and the rear panel 112 by using the noise radiation characteristics of the compressor, and the front panel 111 and the rear panel. By providing the sound absorbing material 162 at 112, the noise of the compressor 151 is effectively absorbed and reduced.
도 7 은 본 발명의 실시예에 따른 실외기와 종래 실외기의 소음 정도를 비교하여 나타낸 도이다.7 is a view showing a comparison of the noise level between the outdoor unit and the conventional outdoor unit according to an embodiment of the present invention.
도시한 바와 같이 압축기(151)와 어큐물레이터(152)의 둘레를 흡차음재(161)로 감싸고, 케이싱(110) 벽면에 흡음재(162)를 설치한 본 발명은 종래 흡음재를 사용하지 않은 실외기에 비해 소음이 확실하게 저감됨을 알 수 있다.As shown in the drawing, the sound absorbing material 161 is wrapped around the compressor 151 and the accumulator 152 and the sound absorbing material 162 is installed on the casing 110 wall. It can be seen that the noise is surely reduced.
한편, 압축기(151)와 어큐물레이터(152)의 중심(C)을 이은 선이 케이싱(110)의 길이방향과 이루는 각도는 대략 30도 전후가 바람직하나, 이에 한정하는 것은 아니다.Meanwhile, the angle formed by the line connecting the center C of the compressor 151 and the accumulator 152 with the longitudinal direction of the casing 110 is preferably approximately 30 degrees, but is not limited thereto.
즉, 압축기(151)와 어큐물레이터(152)의 중심을 이은 선이 60도 이하이면 방사하는 소음을 흡음재(162)로 흡수 소산하는 것이 가능하나, 그 이상이 되면 압축기에서 방사하는 소음이 전면패널(111) 및 후면패널(112)에 대하여 수직방향에서 벗어나 차음벽(140) 및 케이싱(110)의 측면을 향하게 되어, 소음이 상기 흡음재(162)에 의해 효과적으로 흡수되지 못하고, 케이싱(110)의 측면과 차음벽(140)으로 통과하게 외부로 방사된다.That is, when the line connecting the center of the compressor 151 and the accumulator 152 is 60 degrees or less, it is possible to absorb and dissipate the radiating noise with the sound absorbing material 162. From the vertical direction with respect to the panel 111 and the rear panel 112 to the side of the sound insulating wall 140 and the casing 110, the noise is not effectively absorbed by the sound absorbing material 162, the casing 110 Radiated to the outside to pass through the side and sound insulation wall 140.
물론, 측면에도 흡음재(162)를 설치할 수 있으나, 이와 같이 측면에 흡음재(162)를 설치하게 될 경우에는 불필요한 흡음재를 사용하게 되어 제조 비용이 비싸지는 단점이 있다.Of course, the sound absorbing material 162 may be installed on the side surface, however, when the sound absorbing material 162 is installed on the side surface, an unnecessary sound absorbing material is used, and thus manufacturing cost is high.
또한, 본 발명은 공기조화기의 실외기 뿐만아니라, 케이싱과 상기 케이싱 내부에 압축기와 어큐물레이터가 설치되는 구조를 갖는 다른 것, 예를 들면 냉장고등에 이용 가능하다.In addition, the present invention can be used not only for the outdoor unit of the air conditioner, but also for the casing and the others having a structure in which the compressor and the accumulator are installed inside the casing, for example, a refrigerator.
이상에서 설명한 바와 같이 본 발명에 따른 공기조화기 실외기는 다음과 같은 효과가 있다.As described above, the outdoor unit of the air conditioner according to the present invention has the following effects.
첫째, 압축기의 소음 발생 특성에 맞추어 소음이 가장 많이 발생하는 방향에 흡차음재, 흡음재를 설치함에 따라 공기조화기 실외기의 소음을 최대한 저감할 수 있는 효과가 있다.First, by installing the sound absorbing and insulating material, the sound absorbing material in the direction in which the most noise in accordance with the noise generation characteristics of the compressor has the effect to reduce the noise of the air conditioner outdoor unit to the maximum.
둘째, 전술한 바와 같이 흡차음재, 흡음재를 설치함에 따라 불필요한 흡차음재, 흡음재의 사용을 방지하여 제조 비용을 절감하는 효과가 있다.Second, as described above, by installing the sound absorbing and insulating material and the sound absorbing material, there is an effect of reducing the manufacturing cost by preventing the use of unnecessary sound absorbing and insulating material, sound absorbing material.
