Description

멀티에어컨의 실외기{outdoor-unit of multi-air-conditioner}Outdoor unit of multi-air conditioner

본 발명은 한 개 또는 두 개의 팬을 가지는 실외기와 다수 개의 실내기로 이루어지는 멀티에어컨에 관한 것으로서, 더욱 상세하게는 실외기의 팬 토출부를 개폐가능한 차폐판을 구비하여 실내기가 모두 작동하지 않는 경우에 실외 열교환 열량을 제어할 수 있도록 한 것이다.The present invention relates to a multi-air conditioner consisting of an outdoor unit having a one or two fans and a plurality of indoor units, and more particularly, an outdoor heat exchanger when the indoor units are not operated by providing a shielding plate that can open and close a fan discharge part of the outdoor unit. It is to control the calories.

일반적으로, 멀티에어컨은 냉방능력과 난방능력을 겸비함과 함께, 실외기 한 대당 다수 개의 실내기가 연결되어 실내기를 선택적으로 운전시킬 수 있는 기기이다.In general, a multi-air conditioner is a device capable of operating an indoor unit selectively by combining a plurality of indoor units per outdoor unit together with cooling and heating capability.

이하, 첨부된 도면을 참조하여, 일반적인 멀티에어컨의 구성을 살펴보면 다음과 같다.Hereinafter, with reference to the accompanying drawings, look at the configuration of a general multi-air conditioner.

멀티에어컨은, 도 1에 도시한 바와 같이, 냉매를 압축시키는 압축기(comp)와, 냉매의 상태를 이용하여 열교환을 수행하는 한 대의 실외기(2) 및 다수대의 실내기(3)와, 상기 실내기에 각각 연결되어 냉매를 팽창시키는 팽창밸브(4)가 포함되어 이루어진다.As shown in FIG. 1, the multi-air conditioner includes a compressor (comp) for compressing a refrigerant, one outdoor unit (2) and a plurality of indoor units (3) for performing heat exchange using the state of the refrigerant, and the indoor unit. An expansion valve 4 is connected to each other to expand the refrigerant.

도시하지는 않았으나, 상기 실외기(2)에는 열교환기 및 팬이 설치된다.Although not shown, the outdoor unit 2 is provided with a heat exchanger and a fan.

상기와 같이 이루어진 멀티에어컨은 다음과 같은 동작을 수행한다.The multi-air conditioner made as described above performs the following operations.

첫째, 냉방운전 시, 상기 압축기에서 압축된 기상냉매는 실외기(2)를 거치면서 실외공기와 열교환을 하여 액상냉매로 상전환되고, 팽창밸브(4)를 거치면서 압력이 하강되며, 실내기(4)를 거치면서 실내공기와 열교환을 하여 기상냉매로 상전환된 후 상기 압축기로 유입된다.First, during the cooling operation, the gaseous refrigerant compressed by the compressor undergoes heat exchange with the outdoor air while passing through the outdoor unit 2 to be phase-converted to the liquid refrigerant, and the pressure decreases while passing through the expansion valve 4. Heat exchange with the room air while passing through)) is converted into the gas phase refrigerant and then introduced into the compressor.

둘째, 난방 운전 시, 압축기에서 압축된 기상냉매는 실내기(3)를 거치면서 실내공기와 열교환을 하여 액상냉매로 상전환되고, 팽창밸브(4)를 거치면서 압력이 하강되며, 실외기(2)를 거치면서 실외공기와 열교환을 하여 기상냉매로 상전환된 후 압축기로 유입된다.Second, during heating operation, the gaseous refrigerant compressed by the compressor undergoes heat exchange with the indoor air while passing through the indoor unit (3), and is phase-converted to the liquid refrigerant, and the pressure drops through the expansion valve (4), and the outdoor unit (2). Through the heat exchange with the outdoor air through the phase conversion into gaseous refrigerant is introduced into the compressor.

한편, 멀티에어컨은 모든 실내기가 운전될 때의 부하를 고려하여 압축기의 용량이 결정되고, 실외기에 설치되는 열교환기(응축기)와 팬도 실내기가 모두 운전될 때 충분히 대응할 수 있는 크기로 설계된다. On the other hand, the multi-air conditioner is determined by the capacity of the compressor in consideration of the load when all the indoor unit is operated, the heat exchanger (condenser) and the fan installed in the outdoor unit is also designed to a size that can sufficiently cope when the indoor unit is operated.

그런데, 이와 같이 설계된 멀티에어컨은 운전되는 실내기의 대수가 적어지면 압축기의 용량이 실내기의 용량보다 커지게 되어, 실외기의 열교환기의 압력이 현저히 떨어지게 되어 냉동효율이 저하되는 문제점이 발생하였다.However, in the multi-air conditioner designed as described above, when the number of indoor units to be operated decreases, the capacity of the compressor becomes larger than that of the indoor unit, and the pressure of the heat exchanger of the outdoor unit is significantly reduced, resulting in a decrease in refrigeration efficiency.

또한, 상기와 같은 종래의 멀티에어컨은 실외기에 구비되는 팬의 용량도 실내기가 모두 운전될 때를 고려하여 설계되어 있기 때문에 저용량 운전 시에도 많은 풍량을 발생시키게 되므로 냉매의 압력 강하를 일으키게 되고, 소비전력도 필요이상으로 소비하게 되는 문제점도 발생하였다.In addition, the conventional multi-air conditioner as described above is designed in consideration of the capacity of the fan provided in the outdoor unit when all the indoor units are operated, so that a large amount of air is generated even during low-capacity operation, causing a pressure drop of the refrigerant. There was also a problem that consumes more power than necessary.

본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출된 것으로서, 실외기의 팬 토출부에 차폐판을 구비하여 실내기가 모두 작동이 되지 않더라도 실외 열교환 열량을 효율적으로 제어할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve the above-described problems, and the object of the present invention is to provide a shield plate at the fan discharge portion of the outdoor unit so that the heat can be efficiently controlled even if the indoor units are not operated.

상기한 목적을 달성하기 위하여, 본 발명은 적어도 한 개 이상의 팬 토출부를 구비한 실외기가 구비되는 멀티에어컨에 있어서; 상기 팬 토출부를 개폐가능하도록 하는 차폐수단이 구비됨을 특징으로 하는 멀티에어컨의 실외기가 제공된다.In order to achieve the above object, the present invention provides a multi-air conditioner having an outdoor unit having at least one fan discharge unit; An outdoor unit of a multi-air conditioner is provided, wherein a shielding means for opening and closing the fan discharge part is provided.
