본 발명은 소음저감 장치 및 그의 제어방법에 관한 것으로, 특히 복수 개의 압축기를 사용하는 텐덤(tandem) 시스템에 있어서, 난방운전 시 실내외 온도와 실내 열교환기 온도를 감지하여 그 감지한 온도에 따라 운전부하를 조절함으로써, 고압형성을 낮추어 냉매의 흐름 속도를 제어하여 실내기의 냉매 이상소음을 감소시키도록 하는 장치 및 방법에 관한 것이다. The present invention relates to a noise reduction device and a control method thereof. In particular, in a tandem system using a plurality of compressors, an indoor and outdoor temperature and an indoor heat exchanger temperature are sensed during heating operation, and an operating load is detected according to the detected temperature. The present invention relates to an apparatus and a method for reducing the abnormal noise of the refrigerant of an indoor unit by controlling the flow rate of the refrigerant by reducing the high pressure formation.

일반적으로 공기 조화기는 실내의 온도를 조절하는 장치의 하나로서, 실내 또는 실외 공기를 흡수하여 이를 가열 또는 냉각한 후 실내에 제공함으로써 실내 온도를 조절하는 장치이다.In general, the air conditioner is a device for controlling the temperature of the room, and is a device for controlling the room temperature by absorbing indoor or outdoor air and heating or cooling it and then providing the room to the room.

도 1은 종래 공기 조화기에서 난방운전에 따른 냉매의 흐름을 보인 예시도로서, 이에 도시된 바와 같이 냉매를 고온 고압의 상태로 만드는 압축기(100)와, 상기 압축기(100)의 토출부에 부착하여 냉방과 난방운전에 따른 냉매 유로를 제어하는 리버싱(reversing) 밸브(110)와, 상기 리버싱 밸브(110)의 토출측에 연결하는 실내 열교환기(120)와, 상기 실내 열교환기(120)의 열교환을 원활히 하는 실내 팬(130)과, 상기 실내 열교환기(120)의 토출부에 연결하는 팽창장치(140)와, 상기 팽창장치(140)의 토출부에 연결하는 실외 열교환기(150) 및 상기 실외 열교환기(150)의 열교환을 원활히 하는 실외 팬(160)으로 구성하는데, 난방운전 시 실내의 온도가 점차적으로 상승함에 따라 실내외 열교환기(120,150)에 흐르는 냉매의 압력이 점차 상승하게 된다. 이때 냉매의 압력의 상승은 실내기에 흐르는 냉매의 유속을 빠르게 하고, 이에 따라 냉매 소음이 증가하게 되는 문제점이 있었다.1 is an exemplary view showing a flow of a refrigerant according to a heating operation in a conventional air conditioner, as shown in the compressor 100 to make the refrigerant at a high temperature and high pressure, and is attached to the discharge portion of the compressor 100 A reversing valve 110 for controlling a refrigerant passage according to cooling and heating operation, an indoor heat exchanger 120 connected to a discharge side of the reversing valve 110, and the indoor heat exchanger 120. The indoor fan 130 for smoothing heat exchange of the gas, an expansion device 140 connected to the discharge part of the indoor heat exchanger 120, and an outdoor heat exchanger 150 connected to the discharge part of the expansion device 140. And an outdoor fan 160 that facilitates heat exchange of the outdoor heat exchanger 150. As the temperature of the room increases gradually during the heating operation, the pressure of the refrigerant flowing in the indoor and outdoor heat exchangers 120 and 150 gradually increases. . At this time, the increase in the pressure of the refrigerant increases the flow rate of the refrigerant flowing in the indoor unit, thereby increasing the refrigerant noise.

따라서, 종래에는 압력의 형성을 낮추기 위하여 실내 열교환기(120)의 센서 온도에 따라 실외 팬(160)을 온/오프(on/off) 하여 압력의 형성을 제어하였다. Accordingly, in order to lower the pressure, the pressure is controlled by turning on / off the outdoor fan 160 according to the sensor temperature of the indoor heat exchanger 120.

그러나, 상기 방법의 경우에 실내기의 과도한 압력 형성을 낮추기 위해 실외 팬을 온/오프 하는 제어를 수행하는데 있어서, 온/오프에 따른 압력의 편차가 과도하여 이상소음의 차이가 크게 나타남으로 인하여 사용자에게 더 큰 불쾌감을 유발하는 문제점이 있었다. However, in the case of performing the control to turn on / off the outdoor fan in order to reduce the excessive pressure build-up of the indoor unit, the difference in the pressure due to the on / off is excessive so that the difference in abnormal noise appears to the user. There was a problem that caused greater discomfort.

또한, 종래에는 실내온도와 설정온도의 온도차가 적은 경우, 예를 들어 1℃차가 나는 경우에는 1℃를 올리기 위해 단순하게 압축기를 구동하는데, 실외 온도가 낮은 경우에는 압축기의 구동 시간이 길어지게 되어 압축기 구동에 따른 소음과 열 효율이 떨어지는 문제점이 있었다. In addition, in the related art, when the temperature difference between the indoor temperature and the set temperature is small, for example, when the temperature difference is 1 ° C, the compressor is simply driven to increase the temperature by 1 ° C. However, when the outdoor temperature is low, the driving time of the compressor becomes long. There is a problem in that noise and thermal efficiency are lowered according to the compressor driving.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 난방운전 시 실내외 온도를 감지하여 감지한 온도에 따른 압축기 운전제어를 통하여 운전부하를 조절함으로써, 고압형성을 낮추어 냉매의 흐름 속도를 제어하여 실내기의 냉매 이상소음을 감소시키고, 열 효율을 증대시키도록 하는 장치 및 방법을 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned conventional problems, and by adjusting the operating load through the compressor operation control according to the sensed temperature by sensing the indoor and outdoor temperature during heating operation, by reducing the high-pressure formation flow of the refrigerant It is an object of the present invention to provide an apparatus and method for controlling the speed to reduce the abnormal noise of the refrigerant in the indoor unit and to increase the thermal efficiency.

또 다른 목적으로, 난방운전 시 실내 열교환기 온도를 감지하여 감지한 온도에 따른 실외 팬의 속도를 가변하여 운전부하를 조절함으로써, 고압형성을 낮추어 냉매의 흐름 속도를 제어하여 실내기의 냉매 이상소음을 감소시키고, 전력소모를 적게하도록 하는 장치 및 방법을 제공함에 그 목적이 있다.For another purpose, by controlling the operating load by varying the speed of the outdoor fan according to the detected temperature by detecting the temperature of the indoor heat exchanger during heating operation, by reducing the high-pressure formation to control the flow rate of the refrigerant to the abnormal noise of the indoor unit It is an object of the present invention to provide an apparatus and method for reducing power consumption and reducing power consumption.

이와 같은 목적을 달성하기 위한 본 발명 공기조화기 실내기의 소음저감 제어방법은, 공기조화기 실내기의 소음저감을 위한 운전제어에 있어서, 난방운전 모드 시 난방 부하를 측정한 후, 난방 부하의 크기에 따라 사전에 설정한 복수 개의 운전제어구간 중 상기 측정한 난방 부하에 대응하는 운전제어구간을 선택하고, 상기 선택한 운전제어구간의 능력범위에서 상기 공기조화기의 난방능력을 가변 제어하는 것을 특징으로 한다.The noise reduction control method of the indoor unit of the air conditioner of the present invention for achieving the above object, in the operation control for noise reduction of the indoor unit of the air conditioner, after measuring the heating load in the heating operation mode, the size of the heating load And selecting an operation control section corresponding to the measured heating load from a plurality of preset operation control sections, and variably controlling the heating capability of the air conditioner in the capability range of the selected operation control section. .
