Description
본 발명은 실내 공기를 항상 쾌적한 조건으로 유지할 수 있도록 흡입공기를 처리하여 건물 또는 방에 공급하는 공기조화기에 관한 것으로서, 특히 공기의 유입량이 다른 부분에 비해 상대적으로 작은 부분의 일부를 절단하는 공기조화기용 열교환기에 관한 것이다.The present invention relates to an air conditioner that processes intake air and supplies it to a building or a room so that indoor air is always maintained in a comfortable condition. Particularly, an air conditioner that cuts a part of a portion whose air inflow is relatively small compared to other parts. It relates to a heat exchanger for air.
일반적으로 공기조화기는 일체형과 분리형으로 구분되는데, 상기한 일체형과 분리형은 기능적으로는 같지만 일체형은 냉각 방열의 기능을 일체화하여 가옥의 벽에 구멍을 뚫거나 창에 장치를 걸어서 직접 설치한 것이고, 분리형은 실내측에 냉각 장치를 설치하고 실외측에 방열 및 압축 장치를 설치하여 서로 분리된 두 장치간을 냉매 배관으로 연결시킨 것이다.In general, the air conditioner is divided into an integrated type and a detachable type. The integrated type and the separated type are functionally the same, but the integrated type integrates the function of cooling heat dissipation, and is directly installed by drilling a hole in a wall of a house or hanging a device on a window. The cooling device is installed on the indoor side and the heat dissipation and compression device is installed on the outdoor side to connect the two separated devices with refrigerant pipes.
상기와 같은 분리형 공기조화기는 크게 냉각기능을 수행하는 실내기와, 방열 및 압축기능을 수행하는 실외기와, 상기 실내기와 실외기를 서로 연결시키는 냉매배관으로 구성되고, 상기 실내기와 실외기에는 각각 냉매와 공기를 서로 열교환시키기 위한 열교환기가 설치된다.The separate type air conditioner includes an indoor unit that performs a cooling function, an outdoor unit that performs a heat dissipation and compression function, and a refrigerant pipe that connects the indoor unit and the outdoor unit to each other, and the indoor unit and the outdoor unit respectively provide refrigerant and air. Heat exchangers for heat exchange with each other are provided.
종래 기술에 따른 공기조화기용 열교환기가 적용된 실외기는 도 1에 도시된바와 같이, 실내기를 통해 저온저압의 증기상태가 된 냉매를 압축시켜 고온고압의 증기상태로 변환시키는 압축기(1)와, 상기 압축기(1)를 통해 고온고압의 증기상태가 된 냉매를 주위의 공기와 열교환시켜 냉매를 상온고압의 액상태로 응축시키는 열교환기(3)와, 상기 열교환기(3)를 통과하도록 실외의 공기를 흡입하여 강제 유동시키는 실외팬(5)과, 상기 실외팬(5)에 동력을 공급하는 모터(7)를 포함하여 구성된다.The outdoor unit to which the heat exchanger for an air conditioner according to the prior art is applied, as shown in FIG. 1, compresses a refrigerant that has become a low temperature low pressure steam state through an indoor unit and converts the refrigerant into a high temperature high pressure steam state, and the compressor Heat exchanger (3) for condensing the refrigerant into a liquid state at room temperature and high pressure by heat-exchanging the refrigerant that has become a high temperature and high pressure vapor state through (1), and the outdoor air to pass through the heat exchanger (3) It comprises an outdoor fan (5) for suction and forced flow, and a motor (7) for supplying power to the outdoor fan (5).
여기서, 상기 열교환기(3)는 도 1 및 도 2에 도시된 바와 같이 냉매관과 전열핀으로 구성되어 냉매와 공기 사이의 열교환을 수행하는 2열의 몸체부(3A)(3B)로 이루어져 있다.Here, the heat exchanger (3) is composed of two rows of body parts (3A) (3B) consisting of a refrigerant pipe and the heat transfer fins to perform heat exchange between the refrigerant and the air, as shown in FIGS.
또한, 상기 열교환기(3)는 실외기의 전체 체적을 감소시키기 위하여 'ㄱ' 모양으로 구부러져 있다.In addition, the heat exchanger (3) is bent in a 'b' shape to reduce the total volume of the outdoor unit.
이와 같이 'ㄱ' 모양으로 구부러진 열교환기는 'ㅡ' 모양의 열교환기에 비해 냉매의 압력손실이 클 뿐만 아니라 절곡된 부위에서 전열핀이 안쪽으로 모여 공기의 유동 측면에서 불리하기는 하지만 체적이 감소되어 생산비용을 절감시킬 수 있기 때문에 널리 사용되고 있는 실정이다.As described above, the heat exchanger bent in a 'b' shape has a higher pressure loss of the refrigerant than the '-' heat exchanger. It is widely used because it can reduce the cost.
또한, 상기 실외팬(5)에는 공기의 유동을 가이드하는 동시에 압력을 증가시키기 위한 목적으로 디퓨져(Diffuser) 역할을 하는 시라우드(Shroud)(6)가 설치되어 있다.In addition, the outdoor fan 5 is provided with a shroud 6 serving as a diffuser for the purpose of guiding the flow of air and increasing the pressure.
상기와 같이 구성된 실외기에서는, 먼저 실내기를 통해 저온저압의 증기상태가 된 냉매가 압축기(1)로 유입되면 상기 압축기(1)는 이 냉매를 압축시켜 고온고압의 증기상태로 변환시킨다.In the outdoor unit configured as described above, when a refrigerant that has become a low-temperature low-pressure vapor state is introduced into the compressor 1 through an indoor unit, the compressor 1 compresses the refrigerant and converts it into a high-temperature high-pressure steam state.
상기와 같이 압축기(1)에서 압축된 냉매는 열교환기(3)로 유입되어 상기 열교환기(3)를 통과하는 동안 실외팬(5)을 통해 열교환기(3) 측으로 흡입된 공기와 서로 열교환되게 된다.As described above, the refrigerant compressed by the compressor 1 is introduced into the heat exchanger 3 to exchange heat with the air sucked to the heat exchanger 3 through the outdoor fan 5 while passing through the heat exchanger 3. do.
이후, 상기 열교환기(3)에서 냉매와의 열교환을 통해 온도가 상승된 공기는 다시 실외로 방출된다.Thereafter, the air whose temperature is increased through heat exchange with the refrigerant in the heat exchanger 3 is discharged to the outside again.
한편, 상기 열교환기(3)에서 공기와의 열교환을 통해 상온고압의 액상태로 응축된 냉매는 팽창장치를 통과하면서 저온저압의 액상태로 변환된 후 실내기로 유입된다.Meanwhile, the refrigerant condensed in the liquid state at room temperature and high pressure through heat exchange with air in the heat exchanger 3 is converted into the liquid state at low temperature and low pressure while passing through the expansion device and then introduced into the indoor unit.
이후, 상기 실내기로 유입된 냉매는 실내기의 증발기를 거치면서 주위의 공기를 냉각시키고, 이렇게 냉각된 공기가 실내로 토출되어 실내의 냉방작용을 수행하게 된다.Thereafter, the refrigerant introduced into the indoor unit cools the surrounding air while passing through the evaporator of the indoor unit, and the cooled air is discharged into the room to perform the cooling operation of the room.
상기와 같이 구성 및 작동되는 실외기에서 열교환기(3)에 의한 냉매와 공기간의 열교환량은 동일조건에서 공기의 유량이 크면 클수록 증가하고, 이렇게 상기 열교환기(3)의 열교환량이 증가되면 냉매의 응축온도가 낮아져 공기조화기 전체의 효율이 좋아지게 된다.In the outdoor unit configured and operated as described above, the heat exchange amount between the refrigerant and the air by the heat exchanger 3 increases as the air flow rate increases, and condensation of the refrigerant increases when the heat exchange amount of the heat exchanger 3 increases. The lower the temperature, the better the overall efficiency of the air conditioner.
그런데, 상기와 같은 실외기의 후방과 측방에서의 공기 유입 속도를 3차원 레이저 도플러 속도계(Laser Doppler Velocimetry)를 이용하여 측정해보면 도 3의 측정 결과에 나타난 바와 같이 측면에서의 공기 유입 속도가 후면에 비해 현격히 작음을 알 수 있다.However, when the air inflow rate at the rear and side of the outdoor unit as described above is measured by using a 3D laser Doppler Velocimetry, the air inflow rate at the side is greater than the rear as shown in the measurement result of FIG. You can see that it is very small.
이렇게 실외기 측면에서의 공기 유입 속도가 후면에서의 공기 유입 속도에 비해 작은 것은 실외기에 사용되고 있는 실외팬(5)의 유동 특성 때문이다.The air inflow rate at the outdoor unit side is smaller than the air inflow rate at the rear side due to the flow characteristics of the outdoor fan 5 used in the outdoor unit.
즉, 상기 실외팬(5)에는 통상 축류팬이 사용되고 있는데 이러한 축류팬은 도 4에 도시된 바와 같이 공기가 축방향으로 유입되어 축방향으로 토출되는 유동 특성을 갖고 있기 때문이다.That is, the axial fan is generally used for the outdoor fan 5 because the axial fan has a flow characteristic in which air is introduced in the axial direction and discharged in the axial direction as shown in FIG. 4.
상기와 같은 실외팬(5)의 유동 특성으로 인해 실외기의 측면은 상기 실외팬(5)의 축방향인 실외기의 후면에 비해 공기 유입 속도가 더 작아져 공기의 유입량이 떨어지게 되고, 결과적으론 상기 열교환기(3)의 측면이 후면에 비해 공기와 냉매 사이의 열교환량도 감소되게 된다.Due to the flow characteristics of the outdoor fan 5 as described above, the side of the outdoor unit has a smaller air inflow rate than the rear side of the outdoor unit in the axial direction of the outdoor fan 5, resulting in a decrease in the inflow of air. The amount of heat exchange between the air and the refrigerant is also reduced on the side of the machine 3 compared to the rear.
따라서, 종래 기술에 따른 공기조화기용 열교환기는 공기와의 열교환량이 전체적으로 균일하지 않고 어떤 한 부분의 열교환량이 다른 부분에 비해 상대적으로 매우 작아져 그 역할을 제대로 수행하고 있지 못하기 때문에 공기조화기의 성능 측면에서 매우 비효율적인 동시에 비용 측면에서도 손실이 큰 문제점이 있었다.Therefore, the heat exchanger for the air conditioner according to the prior art is not the overall heat exchange amount with the air uniformly and the heat exchange amount of one part is relatively small compared to the other parts, so the performance of the air conditioner It was very inefficient in terms of cost and also costly in terms of cost.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 열교환기 중 다른 부분에 비해 유입되는 공기유량이 상대적으로 작거나 동일한 부분의 형상을 개선하여 그 유로저항을 감소시킴으로써 공기와의 열교환량이 전체적으로 균일해져 공기조화기의 열전달 성능이 향상되도록 하는 공기조화기용 열교환기를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, by improving the shape of the relatively small or the same portion of the flow rate of air flow compared to other parts of the heat exchanger by reducing the flow resistance of the heat exchange amount with the air as a whole It is an object of the present invention to provide a heat exchanger for an air conditioner to be uniform to improve the heat transfer performance of the air conditioner.

상기의 목적을 달성하기 위한 본 발명에 따른 공기조화기용 열교환기는, 냉매관과 전열핀으로 구성되어 냉매와 공기와의 열교환을 수행하는 몸체부가 적어도 2열 이상으로 이루어지고; 상기 몸체부 중 적어도 어느 하나는 다른 부분에 비해 공기의 유입량이 상대적으로 작가나 동일한 부분의 유로저항을 감소시켜 공기유량이 증가되도록 절단되는 것을 특징으로 한다.The heat exchanger for an air conditioner according to the present invention for achieving the above object is composed of a refrigerant pipe and a heat transfer fin, the body portion for performing heat exchange between the refrigerant and air comprises at least two rows; At least one of the body portion is characterized in that the inflow of the air relative to the other portion is cut to reduce the flow resistance of the writer or the same portion to increase the air flow rate.
이하, 본 발명의 실시 예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 5는 본 발명의 제 1실시 예에 따른 공기조화기용 열교환기가 도시된 평면도이고, 도 6은 본 발명의 제 1실시 예에 의한 열교환기가 적용된 실외기에서 측면의 풍속 분포를 측정한 결과가 도시된 도면이다.5 is a plan view showing a heat exchanger for an air conditioner according to a first embodiment of the present invention, Figure 6 is a result of measuring the wind speed distribution of the side in the outdoor unit to which the heat exchanger according to the first embodiment of the present invention is shown Drawing.
상기한 도 5를 참조하면, 본 발명의 제 1실시 예에 따른 공기조화기용 열교환기는 냉매관과 전열핀으로 구성되어 냉매와 공기와의 열교환을 수행하는 2열의 몸체부(51)로 이루어지고, 상기 몸체부(51) 중 적어도 어느 하나는 다른 부분에 비해 공기의 유입량이 상대적으로 작거나 동일한 부분의 유로저항이 감소되어 공기유량이 증가되도록 절단된다.Referring to FIG. 5, the heat exchanger for an air conditioner according to the first embodiment of the present invention is composed of a refrigerant pipe and heat transfer fins, and includes two body parts 51 for performing heat exchange between the refrigerant and the air. At least one of the body parts 51 is cut to increase the air flow rate by reducing the flow resistance of the portion where the inflow of air is relatively small or the same as that of the other portion.
더 상세하게는, 상기 각 몸체부(51)들은 실외기의 후면에 위치되는 제 1열교환부(51a)와, 상기 제 1열교환부(51a)와 소정각을 이루도록 절곡되거나 직선 형태로 연결되어 상기 실외기의 측면에 위치되는 제 2열교환부(51b)로 이루어지고, 상기 각 몸체부(51)들 중 적어도 어느 하나는 상기 제 1열교환부(51a)에 비해 공기의유입량이 작은 상기 제 2열교환부(51b)가 소정 길이만큼 절단된다.In more detail, each of the body parts 51 is bent or connected in a straight line to form a predetermined angle with the first heat exchange part 51a positioned at the rear of the outdoor unit, and the first heat exchange part 51a is connected to the outdoor unit. And a second heat exchanger 51b positioned at a side surface of the second heat exchanger 51b, and at least one of the body parts 51 may have a smaller flow rate of air than the first heat exchanger 51a. 51b) is cut by a predetermined length.
여기서, 상기 몸체부(51)의 제 2열교환부(51b)는 50㎜정도 절단되어 있으며, 이러한 제 2열교환부(51b)의 절단 정도는 설계자의 주된 의도에 따라 조절 가능하다.Here, the second heat exchanger 51b of the body 51 is cut about 50 mm, and the degree of cutting of the second heat exchanger 51b is adjustable according to the designer's main intention.
상기와 같이 구성된 본 발명에 따른 공기조화기용 열교환기에서는, 몸체부(51) 중 실외기의 측면에 위치되어 공기의 유입량이 작은 제 2열교환부(51b)의 일부가 절단되므로 그 부분의 공기의 흐름을 막는 유로저항이 감소되어 도 6에 도시된 바와 같이 상기한 실외기 측면으로 유입되는 공기의 풍속이 커지게 된다.In the heat exchanger for an air conditioner according to the present invention configured as described above, a part of the second heat exchange part 51b, which is located on the side of the outdoor unit of the body part 51 and has a small amount of air inflow, is cut off so that the air flows therein. The flow path resistance to block the air flow is reduced to increase the wind speed of the air flowing into the side of the outdoor unit as shown in FIG.
이렇게 상기 제 2열교환부(51b) 측으로 유입되는 공기의 풍속이 커지면 그 부분으로의 공기의 유입량도 함께 증가되어 상기 제 2열교환부(51b)를 통해 이루어지는 냉매와 공기간의 열교환량이 증가되게 된다.As the wind speed of the air flowing into the second heat exchange part 51b increases, the amount of air flowing into the part also increases, thereby increasing the amount of heat exchange between the refrigerant and the air made through the second heat exchange part 51b.
물론, 상기 제 2열교환부(51b)의 일부가 절단되어 공기와 접촉되는 열교환기의 면적이 줄어들기는 하지만 이러한 열교환 면적의 감소로 인해 줄어드는 열교환량은 공기의 유입량 증가로 인해 늘어나는 열교환량으로 충분히 상쇄할 수 있게 된다.Of course, although the area of the heat exchanger in which part of the second heat exchange part 51b is cut and is in contact with air is reduced, the heat exchange amount that is reduced due to the decrease in the heat exchange area is sufficiently offset by the heat exchange amount that is increased due to the inflow of air. You can do it.
따라서, 상기 몸체부(51)중 제 1열교환부(51a)보다 공기의 유입량이 작은 제 2열교환부(51b)의 일부를 절단해주는 것은 상기 제 2열교환부(51b)를 그대로 유지하는 경우와 동등한, 또는 그 이상의 열전달 성능을 가지면서 동시에 열교환기의 체적을 줄여 생산비용을 절감하는 것을 가능하게 해준다.Therefore, cutting a part of the second heat exchange part 51b in which the air flow rate is smaller than the first heat exchange part 51a of the body part 51 is equivalent to the case of maintaining the second heat exchange part 51b as it is. It is possible to reduce the production cost by reducing the volume of the heat exchanger while at the same time having a heat transfer capability of more than or equal to.
한편, 도 7은 본 발명의 제 2실시 예에 따른 공기조화기용 열교환기가 도시된 평면도이고, 도 8은 본 발명의 제 2실시 예에 의한 열교환기가 적용된 실외기에서 측면의 풍속 분포를 측정한 결과가 도시된 도면이다.On the other hand, Figure 7 is a plan view showing a heat exchanger for an air conditioner according to a second embodiment of the present invention, Figure 8 is a result of measuring the wind speed distribution of the side in the outdoor unit to which the heat exchanger according to the second embodiment of the present invention Figure shown.
상기한 도 7을 참조하면, 본 발명의 제 2실시 예에 따른 공기조화기용 열교환기는 몸체부(151) 중 제 1열교환부(151a)보다 상대적으로 공기의 유입량이 작은 제 2열교환부(151b)가 210㎜정도 절단된다. 이때, 상기 제 2열교환부(151b)가 위치되는 실외기 측면으로 유입되는 공기의 풍속 분포를 측정하면 도 8과 같다. 이외의 구성 및 작용효과는 전술한 제 1실시 예와 동일하다.Referring to FIG. 7, the heat exchanger for an air conditioner according to the second embodiment of the present invention has a second heat exchanger 151b having a smaller air inflow amount than the first heat exchanger 151a of the body 151. Is cut about 210 mm. In this case, the air velocity distribution of the air flowing into the side of the outdoor unit where the second heat exchanger 151b is located is as shown in FIG. 8. Other configurations and effects are the same as the first embodiment described above.
한편 다른 실시 예에 따르면, 본 발명의 열교환기 즉 다른 부분에 비해 상대적으로 공기의 유입량이 작은 부분의 일부가 절단된 열교환기는, 몸체부(51)가 2열 이상인 경우에도 적용 가능하다.On the other hand, according to another embodiment, the heat exchanger of the present invention, that is, a portion of the heat exchanger cut off a portion of the air flow is relatively small compared to other parts, it is applicable to the case where the body portion 51 is two or more rows.
또한, 본 발명의 열교환기는 상기 제 1열교환부(51a)와 제 2열교환부(51b)로 이루어진 'ㄱ' 모양의 열교환기만이 아니라 'ㅡ' 또는 'ㄷ' 모양의 열교환기에도 적용 가능하다.In addition, the heat exchanger of the present invention can be applied not only to the heat exchanger having a '-' shape consisting of the first heat exchanger 51a and the second heat exchanger 51b but also to a heat exchanger having a '-' or 'c' shape.
마지막으로, 본 발명의 열교환기는 실외기만이 아니라 실내기에도 동일하게 적용 가능하다.Finally, the heat exchanger of the present invention is equally applicable to indoor units as well as outdoor units.
상기와 같이 구성되고 동작되는 본 발명에 따른 공기조화기용 열교환기는, 열교환기 중 다른 부분에 비해 유입되는 공기유량이 상대적으로 작거나 동일한 부분이 절단됨으로써 그 유로저항이 감소되어 공기의 유입량이 증가하게 되므로 공기와의 열교환량이 전체적으로 균일해져 공기조화기의 열전달 성능이 향상되는 동시에 열교환기의 체적이 감소되어 생산비용이 절감되는 이점이 있다.The heat exchanger for an air conditioner according to the present invention constructed and operated as described above has a relatively small or equal portion of the air flow introduced therein compared to other parts of the heat exchanger, thereby reducing its flow resistance so that the air flow rate increases. Therefore, since the heat exchange amount with the air is uniform, the heat transfer performance of the air conditioner is improved, and the volume of the heat exchanger is reduced, thereby reducing the production cost.
뿐만 아니라, 본 발명은 열교환기로 인한 유로저항이 감소되므로 팬을 작동시키는 모터에 걸리는 부하가 작아져 에너지 효율이 증가되는 이점이 있다.In addition, the present invention has the advantage that the energy efficiency is increased by reducing the load on the motor for operating the fan because the flow resistance due to the heat exchanger is reduced.
