Description

냉장고의 압축기 냉각장치 및 그 냉각방법{}Compressor Chiller of Refrigerator and Cooling Method thereof

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 of a refrigerator and a cooling method thereof, and to a compressor cooling apparatus and a cooling method of a refrigerator that can increase the efficiency of the 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 고온,고압으로 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), 압축기 냉각용의 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 includes a compressor (1) for circulating a refrigeration cycle by compressing a refrigerant at high temperature and high pressure, a cooling fan (2) for cooling the compressor, a power supply unit (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 냉각효율을 향상시킬 수 있도록 할 수 있는 압축기 냉각장치 및 그 냉각방법을 제공하는 것이다.Accordingly, an object of the present invention is to provide a compressor cooling device and a cooling method thereof, which can improve the cooling efficiency of a compressor.

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.

그리고, 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. 또한, 냉장실 및 냉동실에는 고내온도를 감지하기 위한 냉동실온도센서(13)와 냉장실온도센서(23)가 각각 설치되어 있다.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 for discharging the cold air of the evaporators 11 and 21 into the chamber. 25) is installed. In addition, the refrigerating chamber and the freezing chamber are provided with a freezing compartment temperature sensor 13 and a refrigerating compartment temperature sensor 23 for sensing the internal temperature of the refrigerator.

한편, 압축기(1)는 냉동실온도센서(13)와 냉장실온도센서(23)로부터 감지된 고내온도에 기초하여 작동여부가 결정되며, 압축기(1)에 인접한 영역에는 고온으로 압축된 압축기(1)를 냉각시키기 위한 냉각팬(2)이 설치되어 있다. 여기서, 냉각팬(2)은 속도가변적인 구동모터, 예를 들면 BLDC모터이다.On the other hand, the compressor (1) is determined whether to operate based on the internal temperature detected by the freezer compartment temperature sensor (13) and the refrigerating compartment temperature sensor (23), the compressor (1) compressed to a high temperature in the region adjacent to the compressor (1) A cooling fan 2 for cooling the gas is provided. Here, the cooling fan 2 is a speed variable drive motor, for example, a BLDC motor.

도 2는 본 발명에 따른 압축기 냉각장치의 제어블록도이다. 이 도면에 도시된 바와 같이, 마이컴으로 만들어지는 제어부(3)는 냉동실온도센서(13), 냉장실온도센서(23), 냉동실증발기온도센서(14) 및 냉장실증발기온도센서(24)로부터 각 검출신호를 입력받아, 압축기(1), 냉동실팬(15), 냉장실팬(25), 냉각팬(2) 등을 제어한다.2 is a control block diagram of a compressor cooling apparatus according to the present invention. As shown in this figure, the control unit 3 is made of a microcomputer each detection signal from the freezer compartment temperature sensor 13, the refrigerator compartment temperature sensor 23, the freezer compartment evaporator temperature sensor 14 and the refrigerator compartment evaporator temperature sensor 24. The controller 1 controls the compressor 1, the freezer compartment fan 15, the refrigerating compartment fan 25, the cooling fan 2, and the like.

한편, 제어부(3)는 압축기(1)를 효율적으로 냉각하기 위해 압축기(1)의 구동종료후에도 일정시간 냉각팬(2)을 운전시킨다. 이 때 제어부(3)는 압축기(1)가 운전중인 때에는 냉장고의 소음을 고려하여 냉각팬(2)을 통상적인 속도로 구동시키고, 압축기(1)가 운전하지 않을 때에는 압축기(1)의 구동에 따른 소음이 없으므로 냉각팬(2)을 고속으로 구동시킨다.On the other hand, the control unit 3 operates the cooling fan 2 for a predetermined time even after the end of the driving of the compressor 1 in order to cool the compressor 1 efficiently. At this time, the control unit 3 drives the cooling fan 2 at a normal speed in consideration of the noise of the refrigerator when the compressor 1 is in operation, and operates the compressor 1 when the compressor 1 is not in operation. Since there is no noise, the cooling fan 2 is driven at a high speed.

도 3은 본 발명에 따른 압축기 냉각장치의 제어과정을 나타낸 흐름도이다. 이 도면에 도시한 바와 같이, 제어부(3)는 압축기(1)가 구동중인지를 판단하고(S10), 압축기(1)가 구동중일 경우에는 미리 설정된 정상속도(R1)로 냉각팬(2)을 구동시키도록 제어한다(S20). 여기서, 회전속도(R1)는 압축기(1)의 운전시 발생하는 소음과 냉장고에서 요구되는 소음기준치를 고려하여, 냉각팬(2)과 압축기(1)의 동시 구동시 발생되는 소음이 소음기준치를 초과하지 않는 냉각팬(2)의 최대회전속도이다.3 is a flowchart illustrating a control process of the compressor cooling apparatus according to the present invention. As shown in the figure, the controller 3 determines whether the compressor 1 is being driven (S10), and when the compressor 1 is being driven, the control unit 3 operates the cooling fan 2 at a predetermined normal speed R1. Control to drive (S20). Here, the rotational speed R1 is a noise reference value for the noise generated during simultaneous operation of the cooling fan 2 and the compressor 1 in consideration of the noise generated during operation of the compressor 1 and the noise reference value required by the refrigerator. It is the maximum rotational speed of the cooling fan 2 that does not exceed.

한편, 상술한 실시예에서는 압축기(1)의 운전종료후에는 냉각팬(2)의 속도를 고속으로 작동시켰으나, 압축기(1)의 운전 여부에 관계없이 동일한 속도로 제어할 수도 있다. 이 실시예는 냉각팬(2)의 구동모터로 가변모터를 채택하지 않아도 되는 장점이 있으나, 소음관계와 냉각효율적 측면에서는 불리하게 된다. 즉, 냉각팬의 속도를 비교적 고속으로 설정한 경우에는 압축기운전시 소음이 문제가 되고, 비교적 저속으로 설정한 경우에는 소음에서는 유리하나 냉각효율이 떨어지게 되는 문제점이 있다.On the other hand, in the above-described embodiment, the speed of the cooling fan 2 is operated at a high speed after the operation of the compressor 1 ends, but it may be controlled at the same speed regardless of whether the compressor 1 is operated. This embodiment has the advantage of not having to adopt a variable motor as the drive motor of the cooling fan (2), but disadvantages in terms of noise relationship and cooling efficiency. That is, when the speed of the cooling fan is set to a relatively high speed, noise is a problem during compressor operation, and when the speed is set to a relatively low speed, there is a problem in that the cooling efficiency is lowered, although the noise is advantageous.

이상에서 설명한 바와 같이, 본 발명에 따르면, 압축기의 동작종료 후에도 소정의 연장시간동안 냉각팬을 작동시키므로, 냉장고의 소음을 최소화하면서 압축기의 효율을 높일 수 있어 냉장고의 전력손실을 줄임과 동시에 소음도 줄일 수 있는 냉장고의 압축기 냉각장치 및 그 냉각방법이 제공된다.As described above, according to the present invention, since the cooling fan is operated for a predetermined extended time even after the operation of the compressor is finished, the efficiency of the compressor can be increased while minimizing the noise of the refrigerator, thereby reducing the power loss of the refrigerator and reducing the noise. Provided is a compressor cooling device for a refrigerator, and a cooling method thereof.
