2 is a schematic diagram illustrating a refrigerator cooling device operation cycle according to a preferred embodiment of the present invention.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

참고적으로, 이하에서 설명될 본 발명의 구성들 중 종래기술과 동일한 구성에 대해서는 전술한 종래기술을 참조하기로 하고 별도의 상세한 설명은 생략한다.For reference, the same components as those of the conventional art will be described with reference to the above-described prior art, and a detailed description thereof will be omitted.

도 1 및 도 2에 도시된 바와 같이, 본 실시예의 냉장고 냉각장치는, 제1압축기(11)와, 상기 제1압축기(11)에 연결되는 제1컨덴서(21)와, 제2압축기(12)와, 상기 제2압축기(12)에 연결되는 제2컨덴서(22)와, 상기 제1압축기(11)의 운전주기보다 상기 제1,2컨덴서(21,22)를 냉각시키는 냉각팬(23)의 운전주기는 짧거나 동일하도록 제어하는 제어부(미도시)를 포함하는 것을 특징으로 한다.1 and 2, the refrigerator cooling apparatus of the present embodiment includes a first compressor 11, a first condenser 21 connected to the first compressor 11, a second compressor 12 A second condenser 22 connected to the second compressor 12 and a cooling fan 23 for cooling the first and second condensers 21 and 22 from an operation period of the first compressor 11, (Not shown) for controlling the operation period of the fuel cell stack (1) to be shorter or equal to each other.

상기 냉장고 본체는 제1저장실과 상기 제1저장실과 독립된 제2저장실이 구비된다. 상기 제1저장실과 상기 제2저장실은 대용량으로 구비될 수 있다.The refrigerator body includes a first storage room and a second storage room independent of the first storage room. The first storage room and the second storage room may be provided in a large capacity.

상기 제1,2저장실을 각각 냉각시키는 냉각장치는, 상기 제1저장실을 냉각시키는 제1냉각장치와, 상기 제2저장실을 냉각시키는 제2냉각장치를 포함한다.The cooling device for cooling the first and second storage chambers includes a first cooling device for cooling the first storage chamber and a second cooling device for cooling the second storage chamber.

상기 제1,2냉각장치는 각각의 독립된 냉각사이클을 갖는다.The first and second cooling devices have respective independent cooling cycles.

상기 제1,2냉각장치는 냉매를 압축하는 제1,2압축기(11, 12)와, 제1압축기(11)에 연결되는 제1컨덴서(21)와 제2압축기(12)에 연결되는 제2컨덴서(22)와, 제1,2컨덴서(21, 22)에 각각 연결되어 상기 제1,2저장실을 냉각시키는 제1,2증발기(미도시)를 포함한다.The first and second cooling devices include first and second compressors 11 and 12 for compressing refrigerant, a first condenser 21 connected to the first compressor 11 and a second condenser 21 connected to the second compressor 12. [ 2 condenser 22 and a first and second evaporator (not shown) connected to the first and second condensers 21 and 22 to cool the first and second storage chambers.

상기 제1냉각장치는 냉동실(제1저장실)을 냉각시키고, 상기 제2냉각장치는 냉장실(제2저장실)을 냉각시킨다. 따라서, 제1압축기(11)의 한 주기당 운전시간이 제2압축기(12)의 한 주기당 운전시간보다 길 수 있다.The first cooling device cools the freezing chamber (first storage chamber), and the second cooling device cools the refrigerating chamber (second storage chamber). Therefore, the operation time per one cycle of the first compressor 11 may be longer than the operation time per one cycle of the second compressor 12.

또한, 제1컨덴서(21)의 부하가 제2컨덴서(22)보다 크게 된다. Further, the load of the first condenser 21 becomes larger than that of the second condenser 22. [

제1컨덴서(21)는 제2컨덴서(22)보다 넓은 면적을 갖도록 형성된다. The first capacitor 21 is formed to have a larger area than the second capacitor 22.

제1,2압축기(11, 12)와 제1,2컨덴서(21, 22)는 냉장고의 상부 또는 하부에 배치되는 하나의 기계실에 모두 배치된다.The first and second compressors 11 and 12 and the first and second condensers 21 and 22 are all disposed in one machine room disposed at the upper portion or the lower portion of the refrigerator.

제1압축기(11)와 제2압축기(12) 사이에 제1,2컨덴서(21, 22)가 배치된다. The first and second condensers (21, 22) are disposed between the first compressor (11) and the second compressor (12).

제1,2컨덴서(21, 22)와 제1압축기(11) 사이에 배치되어 제1,2컨덴서(21, 22)를 모두 강제냉각시키는 하나의 냉각팬(23)을 더 포함한다. And one cooling fan 23 disposed between the first and second condensers 21 and 22 and the first compressor 11 for forcedly cooling the first and second condensers 21 and 22.

제1컨덴서(21)와 냉각팬(23) 사이에 제2컨덴서(22)가 배치되어, 제2컨덴서(22)는 제1컨덴서(21)보다 냉각팬(23)에 더 근접하도록 배치된다. 따라서, 냉각팬(23)을 작동시킬 때 공기는 제1컨덴서(21)에서 제2컨덴서(22)로 흐르게 되어 제2컨덴서(22)도 냉각되게 된다. 이와 같이 배치되어 냉각효율을 더욱 향상시킬 수 있다.A second condenser 22 is disposed between the first condenser 21 and the cooling fan 23 so that the second condenser 22 is disposed closer to the cooling fan 23 than the first condenser 21. [ Therefore, when the cooling fan 23 is operated, air flows from the first condenser 21 to the second condenser 22 so that the second condenser 22 is also cooled. The cooling efficiency can be further improved.

상기 제어부는 제1압축기(11)의 운전주기보다 제1,2컨덴서(21,22)를 냉각시키는 냉각팬(23)의 운전주기를 짧거나 동일하도록 제어한다. 도 2에는 냉각팬(23)의 운전주기가 제1압축기(11)의 운전주기와 동일하게 제어되는 것이 나타나 있다.The controller controls the operation period of the cooling fan 23 for cooling the first and second condensers 21 and 22 to be shorter than or equal to the operation period of the first compressor 11. [ 2 shows that the operation period of the cooling fan 23 is controlled to be the same as the operation period of the first compressor 11. [

따라서, 상기 제어부는 제1압축기(11)가 온일 때 냉각팬(23)을 작동시키고, 제1압축기(11)가 오프일 때 냉각팬(23)을 정지시킨다.Accordingly, the control unit operates the cooling fan 23 when the first compressor 11 is on and stops the cooling fan 23 when the first compressor 11 is off.

따라서, 상기 제어부로 인해, 냉각팬(23)의 운전율은 감소시키는 동시에 고부하인 제1컨덴서(21) 뿐만 아니라 제2컨덴서(22)까지도 효과적으로 냉각시킬 수 있다.Accordingly, the control unit can reduce the operation rate of the cooling fan 23, and can effectively cool not only the first condenser 21 having a high load but also the second condenser 22.

나아가, 상기 제어부는 제1압축기(11)가 오프일 때 제2압축기(12)도 오프시킨다.Further, the controller turns off the second compressor 12 when the first compressor 11 is off.

또한, 상기 제어부는 제1압축기(11)가 오프된 상태에서 제2압축기(12)의 구동조건이 도래하면, 제2압축기(12)의 구동시점을 제1압축기(11) 구동시까지(제1압축기(11)의 구동조건이 도래할 때까지) 지연시킬 수 있다. 상기 구동조건은 제1,2저장실의 온도(각 저장실의 온도를 감지하는 센서를 각각 구비할 수 있다.)와 설정된 목표온도를 비교하여 저장실의 온도가 목표온도보다 높으면 각 저장실을 냉각시키는 압축기를 온시키는 것을 의미한다.When the driving condition of the second compressor 12 comes in a state where the first compressor 11 is off, the control unit controls the driving time of the second compressor 12 until the first compressor 11 is driven 1 compressor (11) is coming). The driving conditions include a compressor for cooling each storage compartment when the temperature of the storage compartment is higher than a target temperature by comparing the temperature of the first and second storage compartments (each sensor may include a sensor for sensing the temperature of each storage compartment) It means to turn on.

따라서, 상기 제어부는 제1,2압축기(11,12)가 모두 온일때 냉각팬(23)을 작동시키고, 제1,2압축기(11,12)가 모두 오프일 때에는 냉각팬(23)을 정지시키도록 제어할 수 있다.Accordingly, when the first and second compressors 11 and 12 are all turned on, the control unit operates the cooling fan 23, and when both the first and second compressors 11 and 12 are off, the cooling fan 23 is stopped .
