Description
본 발명은 냉장고의 압축기 냉각장치 및 그 냉각방법에 관한 것으로, 압축기의 온도를 적절하게 냉각시켜 압축기의 효율을 높이고 소비전력을 절감할 수 있는 냉장고의 압축기 냉각장치 및 그 냉각방법에 관한 것이다.The present invention relates to a compressor cooling apparatus for a refrigerator and a cooling method thereof, and more particularly, to a compressor cooling apparatus for a refrigerator and a cooling method thereof, which can increase the efficiency of a compressor and reduce power consumption by appropriately cooling the temperature of the compressor.
냉장고는 일반적으로 비교적 저온의 냉동실과 비교적 고온의 냉장실을 가지며, 이들 냉동실과 냉장실내에 수용된 음식물을 냉각하기 위한 냉동시스템을 구비한다. 일반적인 냉동시스템은, 냉매를 압축하는 압축기, 압축기로부터의 냉매를 응축하는 응축기 및 응축기로부터의 냉매를 증발시켜 냉기를 발생시키는 증발기로 이루어진다.Refrigerators generally have a relatively low temperature freezer compartment and a relatively high temperature refrigerating compartment, and include a refrigerating system for cooling the food contained in the freezer compartment and the refrigerating compartment. A general refrigeration system includes a compressor for compressing a refrigerant, a condenser for condensing the refrigerant from the compressor, and an evaporator for evaporating the refrigerant from the condenser to generate cold air.
여기서, 압축기는 고온고압으로 냉매를 압축한다. 압축기의 구동중에 압축기가 고온의 상태로 되면 효율이 떨어지게 되므로 압축기가 작동하기 좋은 온도로 냉각시켜 줄 필요가 있다. 이에 따라, 압축기에 냉각팬이 구비되어 압축기의 회전과 동시에 냉각팬도 같이 회전하여 압축기를 냉각시키는 타입의 압축기 냉각장치가 있다.Here, the compressor compresses the refrigerant at high temperature and high pressure. When the compressor is in a high temperature state while the compressor is running, the efficiency is lowered. Therefore, the compressor needs to be cooled to a temperature suitable for operation. Accordingly, there is a compressor cooling apparatus of a type in which a cooling fan is provided in the compressor to rotate the cooling fan and rotate the cooling fan at the same time.
도 4는 종래의 냉장고의 압축기 냉각을 위한 개략적 회로도이다. 이러한 종래 냉장고의 압축기 냉각장치는, 냉매를 고온고압으로 압축하여 냉동사이클을 순환시키는 압축기(1), 응축기냉각용의 냉각팬(2), 전원을 공급하는 전원공급부(8) 및 냉동실온도센서인 서모스탯(9)으로 이루어져 있다. 압축기(1)와 냉각팬(2)이 전원공급부(8)에 병렬로 연결되어 압축기(1)는 서모스탯(9)에 의해 작동이 제어되고 압축기(1)와 냉각팬(2)의 작동이 동시에 이루어지도록 된다. 압축기(1)가 작동될 때 냉각팬(2)이 회전하고, 압축기(1)가 작동하지 않으면 냉각팬(2)은 회전하지 않게 된다. 여기서, 냉각팬(2)의 회전속도는 일정하게 정해진 정속운동을 하도록 되어 있다.4 is a schematic circuit diagram for cooling a compressor of a conventional refrigerator. The compressor cooling apparatus of the conventional refrigerator is a compressor (1) for circulating a refrigeration cycle by compressing a refrigerant at a high temperature and high pressure, a cooling fan (2) for condenser cooling, a power supply (8) for supplying power, and a freezer temperature sensor. It consists of a thermostat (9). The compressor 1 and the cooling fan 2 are connected in parallel to the power supply 8 so that the compressor 1 is controlled by the thermostat 9 and the operation of the compressor 1 and the cooling fan 2 is prevented. At the same time. When the compressor 1 is operated, the cooling fan 2 rotates, and when the compressor 1 does not operate, the cooling fan 2 does not rotate. Here, the rotational speed of the cooling fan 2 is to perform a constant constant speed movement.
이와 같이, 이러한 종래의 압축기 냉각장치는, 압축기가 작동되지 않는 동안에는 냉각팬이 작동하지 않아 압축기의 냉각이 이루어지지 않게 되어 효율이 저하되고 과도한 전력을 낭비하게 되는 문제점이 있다.As described above, the conventional compressor cooling apparatus has a problem in that the cooling fan is not operated while the compressor is not operated so that the cooling of the compressor is not performed and the efficiency is reduced and excessive power is wasted.
또한 압축기의 냉각효율을 향상시키기 위해 냉각팬의 회전속도를 고속으로 작동시키는 것이 제안되어 있으나, 냉각팬을 고속으로 작동시킬 경우 압축기의 소음과 냉각팬의 소음에 의해 냉장고의 전체적인 소음이 증가하게 된다는 문제점이 있다.In addition, in order to improve the cooling efficiency of the compressor, it is proposed to operate the rotation speed of the cooling fan at high speed, but when operating the cooling fan at high speed, the overall noise of the refrigerator is increased by the noise of the compressor and the noise of the cooling fan. There is a problem.
따라서, 본 발명의 목적은, 압축기의 동작종료 후에도 소정의 연장시간동안 냉각팬을 작동시켜, 냉장고의 소음을 줄이고 압축기의 효율을 높여 소비전력을 절약할 수 있는 압축기 냉각장치 및 그 냉각방법을 제공하는 것이다.Accordingly, an object of the present invention is to provide a compressor cooling apparatus and a cooling method thereof, which operate a cooling fan for a predetermined extended time even after the operation of the compressor is reduced, thereby reducing the noise of the refrigerator and increasing the efficiency of the compressor, thereby saving power consumption. It is.

이하에서는 첨부도면을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 냉장고의 압축기 냉각장치를 갖는 개략적 단면도이다. 도시한 바와 같이, 본 냉장고는, 냉동실(10) 및 냉장실(20)을 형성하는 본체의 후방하부에 설치되어 냉매를 압축하는 압축기와, 본체의 전영역에 걸쳐 배치되어 압축기로부터의 냉매를 응축하는 도시않은 응축기와, 냉동실(10) 및 냉장실(20)의 후벽면내의 냉기덕트내에 설치된 냉동실증발기(11) 및 냉장실증발기(21)를 포함하는 냉동시스템을 가지고 있다.1 is a schematic cross-sectional view of a compressor cooling apparatus of a refrigerator according to the present invention. As shown in the drawing, the refrigerator includes a compressor installed under the main body forming the freezing chamber 10 and the refrigerating chamber 20 to compress the refrigerant, and condensed refrigerant from the compressor disposed over the entire area of the main body. A refrigeration system includes a condenser, not shown, and a freezer compartment evaporator 11 and a refrigerator compartment evaporator 21 installed in a cold air duct in the rear wall of the freezer compartment 10 and the refrigerating compartment 20.
각각의 증발기에는 제상을 위한 제상히터(14, 24)가 설치되어 있고, 각 증발기의 전방에는 각각의 증발기(11, 21)의 냉기를 고내로 토출시키는 냉동실팬(15)과 냉장실팬(25)이 설치되어 있다. 그리고, 압축기(1)에 인접한 영역에는 압축기(1)를 냉각시키기 위한 냉각팬(2)이 설치되어 있으며, 냉각팬은 속도가변가능한 BLDC 모터로 마련된다. 한편, 냉장실 및 냉동실에는 고내온도를 감지하기 위한 냉동실온도센서(13)와 냉장실온도센서(23)가 각각 설치되어 있으며, 압축기(1)에는 압축기(1)의 온도를 감지하기 위한 압축기온도센서(4)가 설치되어 있다. 여기서, 압축기온도센서(4)는 냉각팬(2)의 송풍방향의 반대편에 부착되어 있으며, 이는 냉각팬(2)의 송풍방향에 부착할 경우 정확한 압축기(1)의 표면온도를 정확히 평가할 수 없기 때문이다.Each evaporator is provided with defrost heaters 14 and 24 for defrosting, and in front of each evaporator, a freezing chamber fan 15 and a refrigerating chamber fan 25 for discharging the cold air of the evaporators 11 and 21 into the chamber. Is installed. In the region adjacent to the compressor 1, a cooling fan 2 for cooling the compressor 1 is provided, and the cooling fan is provided as a BLDC motor whose speed is variable. Meanwhile, in the refrigerating chamber and the freezing chamber, a freezing compartment temperature sensor 13 and a refrigerating compartment temperature sensor 23 for detecting a high temperature inside are respectively installed, and the compressor 1 has a compressor temperature sensor for detecting the temperature of the compressor 1. 4) is installed. Here, the compressor temperature sensor 4 is attached to the opposite side of the cooling direction of the cooling fan 2, which cannot accurately evaluate the surface temperature of the compressor 1 when it is attached to the blowing direction of the cooling fan 2. Because.
이러한 냉동시스템을 제어하기 위한 제어부는, 도 2에 도시된 바와 같이, 냉동실온도센서(13) 및 냉장실온도센서(23)로부터 감지된 냉장실온도와 냉동실온도, 냉동실증발기온도센서(14) 및 냉장실증발기온도센서(24)로부터의 각 증발기 온도, 압축기온도센서(4)로부터의 압축기(1) 표면온도에 관한 정보를 입력받아, 압축기(1), 냉동실팬(15), 냉장실팬(25), 냉각팬(2)의 구동을 제어한다.As shown in Figure 2, the control unit for controlling the refrigeration system, the refrigerator compartment temperature and freezer compartment temperature detected from the freezer compartment temperature sensor 13 and the refrigerator compartment temperature sensor 23, the freezer compartment evaporator temperature sensor 14 and the refrigerator compartment evaporator. The evaporator temperature from the temperature sensor 24 and the surface temperature of the compressor 1 from the compressor temperature sensor 4 are inputted to the compressor 1, the freezer compartment fan 15, the refrigerating compartment fan 25, and the cooling unit. The drive of the fan 2 is controlled.
이러한 냉동시스템의 운전은 압축기(1)의 구동여부에 따라 결정되며, 제어부(3)는 냉동실온도센서(13)와 냉장실온도센서(23)로부터 감지된 고내온도에 기초하여 압축기(1)의 작동여부를 결정한다. 그리고, 냉각팬(2)의 구동여부는 압축기(1)의 구동여부와, 압축기온도센서(4)로부터의 감지결과에 따라 결정한다.The operation of the refrigeration system is determined according to whether the compressor 1 is driven, and the controller 3 operates the compressor 1 based on the internal temperature detected by the freezer compartment temperature sensor 13 and the refrigerating compartment temperature sensor 23. Determine whether or not. Then, whether the cooling fan 2 is driven or not is determined according to whether the compressor 1 is driven and the detection result from the compressor temperature sensor 4.
제어부(3)는 냉동실온도와 냉장실온도에 기초하여 압축기(1)를 구동시키며, 이 때, 냉각팬(2)도 동시에 구동시킨다. 그리고, 제어부(3)는 압축기(1)의 구동이 정지되어도 압축기온도센서(4)에 의한 압축기(1) 표면온도에 기초하여 냉각팬(2)의 구동을 제어하게 된다.The control unit 3 drives the compressor 1 based on the freezer compartment temperature and the refrigerating compartment temperature, and at this time, also drives the cooling fan 2 at the same time. The controller 3 controls the driving of the cooling fan 2 based on the surface temperature of the compressor 1 by the compressor temperature sensor 4 even when the driving of the compressor 1 is stopped.
즉, 제어부(3)는 압축기(1)의 구동이 정지하더라도 압축기(1) 표면온도가 일정 온도 이하로 하강하지 아니하면 냉각팬(2)을 계속적으로 구동시키게 되며, 압축기(1)가 구동하지 않더라도 계속적으로 압축기(1) 표면온도를 검출하여 냉각팬(2)의 구동여부를 결정하게 된다. 그리고, 제어부(3)는 압축기(1)의 구동중에는 냉각팬(2)을 미리 설정된 정상속도로 구동시키고, 압축기(1)가 구동하지 아니하는 경우에는 냉각팬(2)을 비교적 고속으로 구동시키게 된다. 이 때, 냉각팬(2)의 정상속도는 압축기(1)의 소음과 냉각팬(2)의 속도에 따른 소음을 고려하여 전체소음이 냉장고의 기준소음을 넘지않는 범위에서 최대속도로 결정된다.That is, the controller 3 continuously drives the cooling fan 2 when the surface temperature of the compressor 1 does not fall below a predetermined temperature even when the operation of the compressor 1 stops, and the compressor 1 does not drive. If not, the surface temperature of the compressor 1 is continuously detected to determine whether the cooling fan 2 is driven. The control unit 3 drives the cooling fan 2 at a predetermined normal speed while the compressor 1 is being driven, and drives the cooling fan 2 at a relatively high speed when the compressor 1 is not driven. do. At this time, the normal speed of the cooling fan 2 is determined as the maximum speed in the range where the total noise does not exceed the reference noise of the refrigerator in consideration of the noise of the compressor 1 and the noise according to the speed of the cooling fan 2.
도 3은 본 발명에 따른 압축기 냉각장치의 제어과정을 나타낸 흐름도이다. 이 도면에 도시한 바와 같이, 제어부(3)는 압축기(1)가 운전중인지를 판단하고(S10), 압축기(1)가 운전중일 경우에는 미리 설정된 정상속도(R1)로 냉각팬(2)을 구동시키도록 제어한다(S20). 그리고, 제어부(3)는 냉장실온도센서(23)와 냉동실온도센서(13)로부터 고내온도가 설정온도에 도달하였음이 감지되면(S30), 압축기(1)의 운전을 종료시키고, 압축기온도센서(4)로부터의 정보를 전달받아 압축기 표면온도(Ｔ)를 검출한다(S40).3 is a flowchart illustrating a control process of the compressor cooling apparatus according to the present invention. As shown in this figure, the control unit 3 determines whether the compressor 1 is in operation (S10), and when the compressor 1 is in operation, operates the cooling fan 2 at a preset normal speed R1. Control to drive (S20). And, if it is detected from the refrigerator compartment temperature sensor 23 and the freezer compartment temperature sensor 13 that the internal temperature has reached the set temperature (S30), the control unit 3 terminates the operation of the compressor 1, the compressor temperature sensor ( Receiving the information from 4) detects the compressor surface temperature (T) (S40).
이 때, 압축기(1)의 운전이 종료된 직후에는 아직 냉각이 충분히 이루어지지 아니하였으므로, 압축기 표면온도(Ｔ)가 최적온도()에 도달하지 아니하며(S50), 제어부(3)는 압축기 표면온도에 따라 냉각팬(2)을 계속적으로 구동시키게 된다. 그리고, 제어부(3)는 압축기(1)의 운전이 종료하였으므로, 냉각팬(2)을 고속으로 구동시켜 냉각시간을 단축시키게 된다(S60).At this time, immediately after the operation of the compressor 1 is finished, the cooling is not sufficiently performed yet, so the compressor surface temperature T is the optimum temperature ( ) Is not reached (S50), and the control unit 3 continuously drives the cooling fan 2 according to the compressor surface temperature. Then, since the operation of the compressor 1 is finished, the control unit 3 drives the cooling fan 2 at high speed to shorten the cooling time (S60).
한편, 압축기온도센서(4)로부터의 압축기 표면온도(Ｔ)가 최적온도() 이하로 하강하면 제어부(3)는 냉각팬(2)의 구동을 정지시키게 된다(S70). 그리고, 압축기(1) 구동정지중에도 제어부(3)는 지속적으로 압축기온도센서(4)로부터의 정보를 입력받아 외부의 조건에 따라 압축기(1) 표면온도가 상승하면 냉각팬(2)을 구동시키게 된다. 이 때, 냉각팬(2)의 속도는 압축기(1) 표면온도(Ｔ)의 상승정도에 따라 미리 냉각팬(2)의 속도를 설정할 수도 있다.On the other hand, the compressor surface temperature T from the compressor temperature sensor 4 is the optimum temperature ( When lowering below), the control unit 3 stops the driving of the cooling fan 2 (S70). The controller 3 continuously receives information from the compressor temperature sensor 4 while the compressor 1 stops driving, and drives the cooling fan 2 when the surface temperature of the compressor 1 rises according to external conditions. do. At this time, the speed of the cooling fan 2 may set the speed of the cooling fan 2 in advance according to the degree of rise of the surface temperature T of the compressor 1.
상술한 실시예에서는 압축기(1)의 구동시에는 냉각팬(2)을 정상속도로 구동하고, 압축기(1)의 구동 완료시에는 냉각팬(2)을 고속으로 구동하였으나, 압축기(1)구동시 냉각팬(2)을 저속으로 구동할 수도 있고, 압축기(1)의 운전중인지 여부에 관계없이 냉각팬(2)을 항상 동일한 속도로 제어할 수도 있다.In the above-described embodiment, the cooling fan 2 is driven at a normal speed when the compressor 1 is driven, and the cooling fan 2 is driven at a high speed when the compressor 1 is completely driven, but when the compressor 1 is driven. The cooling fan 2 may be driven at a low speed, or the cooling fan 2 may always be controlled at the same speed regardless of whether the compressor 1 is in operation.
이상에서 설명한 바와 같이, 본 발명에 따르면, 압축기의 표면온도에 따라 냉각팬으 구동을 제어함으로써, 냉장고의 소음을 최소화하면서 압축기의 효율을 높일 수 있어 냉장고의 전력손실을 줄임과 동시에 소음도 줄일 수 있는 냉장고의 압축기 냉각장치 및 그 냉각방법을 제공한다.As described above, according to the present invention, by controlling the driving of the cooling fan according to the surface temperature of the compressor, it is possible to increase the efficiency of the compressor while minimizing the noise of the refrigerator to reduce the power loss of the refrigerator and at the same time reduce the noise It provides a compressor cooling device and a cooling method thereof.
