본 고안은 냉장고의 냉각장치에 관한 것으로서, 특히 대체냉매를 사용할 때 발생되는 슬러지로 인한 모세관의 막힘을 방지함과 아울러 냉동효과를 상승시킬 수 있도록 한 냉장고의 냉각장치에 관한 것이다.The present invention relates to a cooling device for a refrigerator, and more particularly, to a cooling device for a refrigerator, which prevents capillary clogging due to sludge generated when using an alternative refrigerant and increases a freezing effect.
제1도에서 알 수 있는 바와 같이, 종래의 냉장고 냉각장치는 냉매를 고온고압으로 압축하는 압축기(1)와, 상기 압축기(1)에서 토출된 냉매가스를 방열시켜 액상냉매로 변환시켜 주는 응축기(2)와, 상기 응축기(2)를 통과한 액상냉매를 기화시켜 주변공기를 냉각시켜 주는 증발기(3)와, 상기 증발기(3)에서 미처 기화되지 못한 액상냉매와 기체상태의 냉매를 분리시켜 기체상태의 냉매만이 압축기(1)로 흡입되도록 기액을 분리하여 주는 어큐뮬레이터(5)와, 상기 각 장치들을 연결하여 주는 냉매파이프(5)로 구성된다.As can be seen in Figure 1, the conventional refrigerator cooling apparatus is a compressor (1) for compressing the refrigerant at a high temperature and high pressure, and a condenser for dissipating the refrigerant gas discharged from the compressor (1) into a liquid refrigerant ( 2), an evaporator (3) for vaporizing the liquid refrigerant passing through the condenser (2) to cool the surrounding air, and a liquid refrigerant that has not been vaporized in the evaporator (3) and a gaseous refrigerant by separating the gas. It consists of an accumulator (5) for separating gaseous liquid such that only the refrigerant in a state is sucked into the compressor (1), and a refrigerant pipe (5) for connecting the respective devices.
그리고, 이러한 냉각장치를 지속적으로 순환반복하는 프레온과 같은 냉매가 냉매파이프(5) 내에 주입되엉 사용된다.In addition, a refrigerant such as Freon continuously repeating the cooling device is injected into the refrigerant pipe 5 and used.
그런데, 최근에는 상기한 프레온과 같은 냉매가 대기의 오존층을 파괴한다는 문제가 제기되어 이를 대체할 냉매가 요구되었고, 따라서 R134a 와 같은 대체냉매가 제안되어 사용되고 있다.However, in recent years, a problem that a refrigerant such as freon destroys the ozone layer in the air has been raised, and a coolant to replace it has been required.
그러나, 상기한 대체냉매는 비중이 무겁고 분자구조가 균일하지 못하여 상술한 냉각장치를 순환하면서 슬러지가 발생하여 모세관을 폐쇄시키게 됨으로써 냉장고의 냉각성능이 현저하게 저하되는 문제를 야기시켰다.However, the alternative refrigerant has a heavy specific gravity and a non-uniform molecular structure, causing sludge generated by circulating the above-mentioned cooling apparatus to close the capillary, causing a problem that the cooling performance of the refrigerator is significantly reduced.
본 고안은 이와 같은 종래 문제점을 감안하여 이를 해결하고자 안출한 것으로, 대체냉매의 슬러지에 의한 모세관 막힘현상을 제거하여 냉각성능이 우수한 냉장고의 냉각장치를 제공하고자 함에 그 목적이 있다.The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a cooling device of a refrigerator having excellent cooling performance by removing capillary clogging caused by sludge of an alternative refrigerant.
본 고안은 이러한 목적을 달성하기 위하여, 압축기, 응축기, 모세관, 증발기 및 어큐뮬레이터와; 냉매가 자유로이 순환되도록 이들 각 장치들이 순차로 연통되게 연결시키도록 설치되는 냉매파이프로 이루어지는 냉장고의 냉각장치에 있어서, 상기 모세관은 상기 어큐뮬레이터를 관통하여 상기 증발기에 연결되도록 설치되고, 상기 냉매파이프의 응축기 출구측과 증발기 입구측을 연결하도록 상기 모세관과 병렬로 설치되는 별도의 보조모세관이 구비되는 것에 의해 달성되게 된다.The present invention provides a compressor, a condenser, a capillary, an evaporator, and an accumulator to achieve this object; In the cooling device of the refrigerator consisting of a refrigerant pipe is installed so as to connect each of these devices in order to communicate freely circulating the refrigerant, the capillary tube is installed to be connected to the evaporator through the accumulator, the condenser of the refrigerant pipe This is achieved by providing a separate auxiliary capillary tube installed in parallel with the capillary tube to connect the outlet side and the evaporator inlet side.
이하에서는, 본 고안에 따른 바람직한 일 실시예에 대한 구성 및 작용효과를 첨부도면을 참조하여 보다 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings, the configuration and operation effects for a preferred embodiment according to the present invention will be described in more detail.
제2도는 본 고안에 따른 냉각장치 및 냉매의 흐름을 도식적으로 나타낸 구성도이다.2 is a schematic diagram showing the flow of the cooling device and the refrigerant according to the present invention.
도면에서와 같이, 압축기(1), 응축기(2), 모세관(4), 증발기(3) 및 어큐뮬레이터(5)가 순차로 냉매파이프(6)에 의해 상호 연통되도록 연결 설치된다. 여기에서, 상기 모세관(4)은 상기 어큐뮬레이터(5)의 내부를 관통하여 설치된다.As shown in the figure, the compressor 1, the condenser 2, the capillary tube 4, the evaporator 3, and the accumulator 5 are sequentially connected to each other by the refrigerant pipe 6 are connected. Here, the capillary tube 4 is installed through the interior of the accumulator 5.
한편, 상기 냉매파이프(6)에는 응축기(2)의 출구측과 증발기(3)의 입구측을 연결하는 별도의 보조모세관(8)이 상기 어큐뮬레이터(5)를 관통하여 증발기(3)에 연결된 모세관(4)과 병렬로 배설된다. 또한, 상기 보조모세관(8)은 상기 어큐뮬레이터(5)와 압축기(1) 사이를 연결하는 냉매파이프인 석션파이프(9)의 외주 일부를 다수회 감아 설치된다.On the other hand, the refrigerant pipe (6) is a capillary tube connected to the evaporator (3) through a separate auxiliary capillary tube (8) connecting the outlet side of the condenser (2) and the inlet side of the evaporator (3) Exposed in parallel with (4). In addition, the auxiliary capillary tube 8 is installed by winding a portion of the outer circumference of the suction pipe 9, which is a refrigerant pipe connecting between the accumulator 5 and the compressor 1.
이러한 구성에 따른 본 고안의 작용을 살펴보면, 상기 압축기(1)에서 토출된 고온고압의 냉매가스는 상기 응축기(2)로 보내지며, 상기 응축기(2)를 거치면서 외부로 열을 방출하여 액화된다. 이렇게 액화된 냉매는 상기 응축기(2)의 출구측에서 모세관(4)과 보조모세관(8)으로 분급되어 압력이 강하된 채 증발기(3)로 흡입된다.Looking at the operation of the present invention according to this configuration, the high temperature and high pressure refrigerant gas discharged from the compressor (1) is sent to the condenser (2), while releasing heat to the outside through the condenser (2) is liquefied . The liquefied refrigerant is classified into a capillary tube 4 and an auxiliary capillary tube 8 at the outlet side of the condenser 2 and is sucked into the evaporator 3 while the pressure drops.
즉, 응축기(2)를 거친 냉매의 일부는 어큐뮬레이터(5)를 관통하여 설치된 모세관(4)을 거치면서 압력이 강하게 되며, 미처 방열되지 못하고 잔존하는 미열이 어큐뮬레이터(5) 내부에 잔류하는 액상의 냉매와 열교환된다. 따라서, 어큐뮬레이터(5) 내부에 잔류하는 액냉매의 일부가 마저 기화되게 되어 잔류하는 액냉매량이 줄어들며, 반면에 모세관(4)을 통과하는 액상의 냉매는 완전하게 저온저압화 되게 된다.That is, some of the refrigerant passing through the condenser (2) through the capillary tube (4) is installed through the accumulator (5) is a strong pressure, the heat of the liquid phase remaining in the accumulator (5) remaining unheated Heat exchange with the refrigerant. Therefore, a part of the liquid refrigerant remaining in the accumulator 5 is even evaporated to reduce the amount of remaining liquid refrigerant, while the liquid refrigerant passing through the capillary tube 4 is completely low temperature and low pressure.
한편, 분급된 나머지 냉매는 보조모세관(8)을 통과하면서 압력이 강하되게 되는 바, 이때에 어큐뮬레이터(5)에서 압축기(1)로 흡입되는 통로인 석션파이프(9) 상에서 귀환되는 냉매가스와 열교환되면서 완전히 저온저압화 된 후에 증발기(3)로 흘러들어 간다.On the other hand, the remaining refrigerant is passed through the auxiliary capillary tube 8, the pressure is reduced, at this time, the heat exchanged with the refrigerant gas returned on the suction pipe (9) which is a passage suctioned from the accumulator (5) to the compressor (1) While completely low temperature and low pressure flows into the evaporator (3).
따라서, 증발기(3)에서는 온도가 일정할 때 압력이 낮을수록 기화가 잘 일어난다는 보일샤를의 법칙에 따라 기화작용이 원활하게 진행되므로 냉각성능이 향상되게 된다.Accordingly, in the evaporator 3, the cooling performance is improved because the evaporation process proceeds smoothly according to Boyle's law that the lower the pressure, the better the vaporization occurs.
아울러, 상술한 바와 같이 모세관(4)과 보조모세관(8)을 통하여 액상냉매가 분급되므로 각 모세관(4,8)에 축적되는 슬러지 양이 작아지게 되며, 따라서 슬러지에 의한 모세관 막힘현상이 현저하게 줄어들게 된다.In addition, since the liquid refrigerant is classified through the capillary tube 4 and the auxiliary capillary tube 8 as described above, the amount of sludge accumulated in each of the capillary tubes 4 and 8 is reduced, so that the capillary clogging phenomenon due to the sludge is remarkably. Will be reduced.
이상에서 살펴본 바와 같이, 본 고안은 냉매의 흐름을 분급시켜 주는 보조모세관을 채용함으로써, 대체냉매 사용할 때 발생되는 슬러지에 의한 모세관 막힘현상을 현저하게 줄이는 효과를 제공한다.As described above, the present invention employs an auxiliary capillary tube that classifies the flow of the refrigerant, thereby providing an effect of significantly reducing the capillary clogging caused by the sludge generated when using the alternative refrigerant.
나아가서, 두 개의 모세관을 사용함으로서 냉매의 압력을 확실하게 강하시킬수 있게 되어 냉장고의 냉각성능을 현저히 향상시키는 효과도 함께 제공한다.Furthermore, by using two capillaries, the pressure of the refrigerant can be reliably lowered, thereby providing an effect of significantly improving the cooling performance of the refrigerator.
