여기서, 냉동사이클은, 도 1에 도시된 바와 같이, 냉매를 압축하는 압축기(1)와, 압축된 냉매를 등압응축시키는 응축기(2)와, 응축된 냉매를 단열팽창시키는 모세관(3)과, 냉장실과 냉동실에 각각 구비되어 팽창된 냉매를 등압증발시키는 냉장실용 증발기(4)와 냉동실용 증발기(5)로 이루어진다.Here, the refrigeration cycle, as shown in Figure 1, a compressor (1) for compressing the refrigerant, a condenser (2) isocondensing the compressed refrigerant, a capillary tube (3) for adiabatic expansion of the condensed refrigerant, The refrigerator compartment evaporator 4 and the freezer compartment evaporator 5 are respectively provided in the refrigerating compartment and the freezing compartment for isothermally evaporating the expanded refrigerant.
이와 더불어, 냉동사이클은, 상기 응축기(2)에서 응축된 냉매가 분지(分枝)된 유로(流路)를 따라 상기 냉장실용 증발기(4)나 냉동실용 증발기(5)로 선택적으로 유입되도록 상기 유로의 분지점에 구비되는 삼방밸브(6)와, 응축기(2)측에 구비되어 응축기 또는 압축기(1)를 냉각시키는 응축기팬(2a)과, 냉장실용 증발기(4)측에 구비되어 냉장실용 증발기에서 열교환되는 공기를 강제대류시켜 열교환을 촉진시키는 냉장실용 증발기팬(4a)과, 냉동실용 증발기(5)측에 구비되어 냉동실용 증발기에서 열교환되는 공기를 강제대류시켜 열교환을 촉진시키는 냉동실용 증발기팬(5a)이 더 포함되어 이루어진다.In addition, the refrigeration cycle is such that the refrigerant condensed in the condenser 2 selectively flows into the refrigerating chamber evaporator 4 or the freezing chamber evaporator 5 along a branched flow path. The three-way valve 6 provided at the branch point of the flow path, the condenser fan 2a provided on the condenser 2 side and cooling the condenser or compressor 1, and the refrigerating chamber evaporator 4 side, A refrigerator compartment evaporator fan 4a for forced convection of the heat exchanged air in the evaporator to promote heat exchange, and a freezer compartment evaporator provided on the side of the freezer compartment evaporator 5 to forcibly convection the heat exchanged in the freezer compartment evaporator to promote heat exchange. The fan 5a is further included.
이하, 상기와 같이 이루어진 냉동사이클을 갖는 냉장고의 동작을 설명하면 다음과 같다.Hereinafter, the operation of the refrigerator having a refrigeration cycle made as described above is as follows.
첫째, 냉장실용 증발기(4)와 냉동실용 증발기(5)가 모두 가동되는 RF 사이클 운전시, 냉매가 냉장실용 증발기로 흐르도록 삼방밸브(6)가 열리고, 압축기(1)에서 압축된 기상냉매는 응축기(2)를 지나면서 고외(庫外)공기와 열교환을 하여 액상(液狀)냉매로 상전환되고, 모세관(3)을 지나면서 압력이 하강되며, 냉장실용증발기(4)와 냉동실용 증발기(5)를 순차적으로 지나면서 냉장실/냉동실내의 공기와 각각 열교환을 하여 기상(氣狀)냉매로 상전환된 후 압축기로 유입되게 된다.First, in the RF cycle operation in which both the refrigerator compartment evaporator 4 and the freezer compartment evaporator 5 are operated, the three-way valve 6 is opened so that the refrigerant flows into the refrigerator compartment evaporator, and the gaseous refrigerant compressed by the compressor 1 is As it passes through the condenser (2) and exchanges heat with the outside air, it is phase-converted to the liquid refrigerant, and the pressure drops through the capillary tube (3), and the evaporator for the refrigerator compartment (4) and the freezer compartment are evaporators. After passing through (5) sequentially, the heat exchanged with the air in the refrigerating chamber / freezing chamber, respectively, is converted into gaseous refrigerant and then introduced into the compressor.
둘째, 냉동실용 증발기(5)만 가동되는 F 사이클 운전시, 냉매가 냉동실용 증발기로만 흐르도록 삼방밸브(6)가 열리고, 압축기(1)에서 압축된 기상냉매는 응축기(2)를 지나면서 고외공기와 열교환을 하여 액상냉매로 상전환되고, 모세관(3)을 지나면서 압력이 하강되며, 냉동실용 증발기(5)를 지나면서 냉동실 공기와 열교환을 하여 기상냉매로 상전환된 후 압축기로 유입되게 된다.Second, during the F cycle operation in which only the freezer compartment evaporator 5 is operated, the three-way valve 6 is opened so that the refrigerant flows only to the freezer compartment evaporator, and the gaseous phase refrigerant compressed by the compressor 1 passes through the condenser 2 and Heat exchange with the air to phase change into a liquid refrigerant, the pressure is lowered through the capillary tube (3), passing through the freezer compartment evaporator (5), the heat exchange with the freezer compartment air is phase-converted to the gas phase refrigerant to enter the compressor do.
하지만, 상기와 같이 이루어진 냉장고의 냉동사이클은 다음과 같은 문제를 가지고 있다.However, the refrigeration cycle of the refrigerator made as described above has the following problems.
냉장실용 증발기(4)의 압력 및 온도는 냉동실용 증발기(5)의 압력 및 온도보다 높게 나타나게 되는데, 이는 기본적인 냉동사이클 원리에 기인된 것으로서, 응축기(2)와 비교적 가까운 곳의 압력 및 온도가 응축기와 먼 곳의 압력 및 온도보다 높기 때문이며, 이러한 압력 및 온도차로 인해 다음과 같은 서머사이펀 현상이 나타나는 문제가 있었다.The pressure and temperature of the refrigerating chamber evaporator 4 will be higher than the pressure and temperature of the freezing chamber evaporator 5, which is due to the principle of the basic refrigeration cycle, where the pressure and temperature relatively close to the condenser 2 are condensers. This is because it is higher than the pressure and temperature far away, and there is a problem that the following thermosiphon phenomenon occurs due to the pressure and temperature difference.
즉, 도 2에 도시된 바와 같이, 냉장고(기기) 기동 오프(off)시, 냉장실용 증발기(4)에 남아있는 액상냉매가 온도 및 압력차에 의해 증발되면서 냉동실용 증발기(5)로 유동하게 되고, 냉동실용 증발기(5)로 유동된 기상냉매는 다시 응축되어 액상냉매로 전환된 후 중력의 영향을 받아 냉장실용 증발기(4)로 유동하는 일련의 순환을 반복하게 된다. 즉 이러한 순환을 반복하는 것이 바로 서머사이펀(thermosiphon) 현상이고, 이러한 서머사이펀 현상에 의해, 비교적 온도가 높은 냉장실용 증발기(4)의 냉매가 비교적 온도가 낮은 냉동실용 증발기(5)로 유동함에 따라 냉동실의 온도가 상승하게 되고, 비교적 온도가 낮은 냉동실용 증발기(5)의 냉매가 비교적 온도가 높은 냉장실용 증발기(4)로 유동함에 따라 냉장실의 온도가 하강하게 된다. 이에 따라, 냉동실 온도는 설정온도보다 높게 올라가게 되고 냉장실 온도는 설정온도보다 낮게되어, 식품을 냉동 및 냉장보관하는데 문제가 있었다.That is, as shown in Figure 2, when the refrigerator (device) start-off (off), the liquid refrigerant remaining in the refrigerator compartment evaporator (4) to flow to the freezer compartment evaporator (5) while evaporating by the temperature and pressure difference Then, the gaseous refrigerant flowed to the freezer compartment evaporator 5 is condensed again and converted to a liquid refrigerant, and then repeats a series of circulations flowing to the refrigerator compartment evaporator 4 under the influence of gravity. That is, repeating this circulation is a thermosiphon phenomenon, and by this thermosiphon phenomenon, the refrigerant of the refrigerating chamber evaporator 4 having a relatively high temperature flows to the freezer evaporator 5 having a relatively low temperature. The temperature of the freezer compartment increases, and the temperature of the refrigerator compartment decreases as the refrigerant of the freezer compartment evaporator 5 having a relatively low temperature flows to the refrigerator compartment evaporator 4 having a relatively high temperature. Accordingly, the freezer compartment temperature is higher than the set temperature and the refrigerator compartment temperature is lower than the set temperature, there is a problem in freezing and refrigerated food storage.

이하, 첨부도면을 참조하여, 본 발명의 바람직한 실시예를 설명하면 다음과같다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described.
도 3은 본 발명에 따른 냉장고의 냉동사이클 구조를 나타낸 블록도이다.3 is a block diagram showing a structure of a refrigeration cycle of a refrigerator according to the present invention.
도면 설명에 앞서, 두 개의 증발기를 갖는 냉장고의 구성은 종래기술에 언급된 바 있으므로, 그 설명을 생략하고, 종래기술과 동일한 구조에 한해서는 종래와 동일한 부호를 부여키로 한다.Prior to the description of the drawings, since the configuration of the refrigerator having two evaporators has been mentioned in the prior art, the description thereof is omitted, and only the same structure as the prior art is given the same reference numeral as in the prior art.
본 발명에 따른 냉장고의 냉동사이클은, 도 3에 도시된 바와 같이, 냉장실과 냉동실에 각각 구비된 냉장실용 증발기(4)와 냉동실용 증발기(5)를 순차적으로 운전시키는 RF 사이클과, 냉동실에 구비된 냉동실용 증발기(5)만을 운전시키는 F 사이클을 갖는 냉장고의 냉동사이클에 있어서, 상기 냉장실용 증발기(4)와 상기 냉동실용 증발기(5)를 연결시키는 연결관상에 구비되어, 기기 오프시 또는 F 사이클 운전시 냉장실용 증발기(4)의 냉매가 냉동실용 증발기(5)로 유동되지 못하도록 연결관을 차단시키고, RF 사이클 운전시 냉장실용 증발기(4)의 냉매가 냉동실용 증발기(5)로 유동되도록 연결관을 개방시키는 서머사이펀 억제 밸브(10)가 포함되어 이루어진다.As shown in FIG. 3, the refrigerating cycle of the refrigerator according to the present invention includes an RF cycle for sequentially operating the refrigerating compartment evaporator 4 and the freezing compartment evaporator 5 provided in the refrigerating compartment and the freezing compartment, respectively, in the freezing compartment. In the refrigerator cycle of the refrigerator having an F cycle for operating only the freezer compartment evaporator (5), it is provided on a connecting pipe connecting the refrigerator compartment evaporator (4) and the freezer compartment evaporator (5), when the device off or F In order to prevent the refrigerant in the refrigerator compartment evaporator 4 from flowing to the freezer compartment evaporator 5 during the cycle operation, and to block the refrigerant from the refrigerator compartment evaporator 4 during the RF cycle operation, the refrigerant in the refrigerator compartment evaporator 5 flows. It comprises a thermosiphon suppression valve 10 for opening the connection pipe.
여기서, 서머사이펀 억제 밸브(10)의 장착 위치를 더 상세히 설명하면 다음과 같다. 도 3에 도시된 바와 같이, 냉동실용 증발기(5)와 압축기(1)와 응축기(2) 그리고 삼방밸브(6)를 순차적으로 직렬연결하는 관을 기본 연결관이라고 하고, 삼방밸브(6)와 냉장실용 증발기(4) 그리고 냉동실용 증발기(5)를 순차적으로 직렬연결하는 관을 RF 사이클 연결관(11)이라고 하며, 삼방밸브(6)와 냉동실용 증발기(5)를 순차적으로 연결하는 관을 F 사이클 연결관(12)이라고 하면, 상기 서머사이펀억제 밸브(10)는, 상기 RF 사이클 연결관과 F 사이클 연결관이 만나는 지점(A)과 상기 냉장실용 증발기(5) 사이에 장착된다.Here, the mounting position of the thermosiphon suppression valve 10 will be described in more detail. As shown in FIG. 3, a pipe connecting the freezer compartment evaporator 5, the compressor 1, the condenser 2, and the three-way valve 6 in series is called a basic connection pipe, and the three-way valve 6 and A tube connecting the refrigerating chamber evaporator 4 and the freezing chamber evaporator 5 in series is called an RF cycle connector 11, and a tube connecting the three-way valve 6 and the freezing chamber evaporator 5 sequentially. In the F cycle connector 12, the thermosiphon suppression valve 10 is mounted between the point A where the RF cycle connector and the F cycle connector meet and the refrigerator compartment evaporator 5.
이하, 도 2 또는 도 3을 참조하여, 본 발명에 따른 냉장고의 냉동사이클의 동작을 설명하면 다음과 같다.2 or 3, the operation of the refrigeration cycle of the refrigerator according to the present invention will be described.
첫째, 기기 오프시, 압축기(1)의 구동이 정지됨과 동시에 서머사이펀 억제 밸브(10)가 닫히면서, 비교적 온도가 높은 냉장실용 증발기(4)의 냉매가 비교적 온도가 낮은 냉동실용 증발기(5)로 유입되는 것이 차단되어, 종래기술에 언급한 서머사이펀 현상을 억제시키게 된다.First, when the apparatus is turned off, the compressor 1 is stopped and the thermosiphon suppression valve 10 is closed, and the refrigerant in the refrigerating chamber evaporator 4 having a relatively high temperature has a relatively low temperature. It is blocked from flowing in, thereby suppressing the thermosiphon phenomenon mentioned in the prior art.
또한, F 사이클 운전시, 압축기(1)가 구동되면서 압축된 냉매는 응축기(2)와 삼방밸브(6)를 거쳐 F 사이클 연결관(12)을 따라 냉동실용 증발기(5)로 유입되어 냉동실의 온도를 낮추게 되는데, 이때도 역시 서머사이펀 억제 밸브(10)가 닫히면서, RF 사이클 운전시 냉장실용 증발기(4)에 남아 있던 비교적 온도가 높은 냉매가 비교적 온도가 낮은 냉동실용 증발기(5)로 유입되는 것이 차단되어, 종래기술에 언급한 서머사이펀 현상을 억제시키게 된다.In addition, during the F cycle operation, the refrigerant compressed while the compressor 1 is driven flows into the freezing chamber evaporator 5 along the F cycle connecting pipe 12 through the condenser 2 and the three-way valve 6 to allow the In this case, the thermosiphon suppressor valve 10 is also closed, and the refrigerant having a relatively high temperature remaining in the refrigerator compartment evaporator 4 during the RF cycle operation flows into the refrigerator compartment evaporator 5 having a relatively low temperature. It is blocked, thereby suppressing the thermosiphon phenomenon mentioned in the prior art.
둘째, RF 사이클 운전시, 압축기(1)가 구동되면서 압축된 냉매는 응축기(2)와 삼방밸브(6)를 거쳐 RF 사이클 연결관(11)을 따라 냉장실용 증발기(4)와 냉동실용 증발기(5)로 각각 순차적으로 유입되어 냉장실 및 냉동실의 온도를 낮추게 되는데, 이때에는 냉장실용 증발기(4)의 냉매가 압축력을 받아 일률적으로 냉동실용 증발기(5)로 유입되므로 서머사이펀 현상이 일어나지 않게 되고, 냉장실용 증발기(4)와 냉동실용 증발기(5)를 모두 거칠 수 있도록 한 사이클이므로, 서머사이펀 억제밸브(10)는 열리게 된다.Second, during the operation of the RF cycle, the refrigerant compressed while the compressor 1 is driven passes through the condenser 2 and the three-way valve 6 along the RF cycle connecting pipe 11 and the refrigerating chamber evaporator 4 and the freezing chamber evaporator ( 5) are sequentially introduced into each to lower the temperature of the refrigerating compartment and the freezing compartment. At this time, since the refrigerant of the refrigerating compartment evaporator 4 is compressed and uniformly flows into the freezing compartment evaporator 5, the thermosiphon phenomenon does not occur. Since the refrigerating chamber evaporator 4 and the freezing chamber evaporator 5 are both cycled, the thermosiphon suppression valve 10 is opened.
결국, 본 발명은, 냉장고의 냉동사이클에 서머사이펀 억제 밸브(10)를 설치하여, 기기 오프시 또는 F 사이클 운전시에는 서머사이펀 억제 밸브를 닫고, RF 사이클 운전시에는 서머사이펀 억제 밸브를 개방시킴에 따라, 서머사이펀 현상을 억제시킬 수 있게 된다.As a result, the present invention provides a thermosiphon suppression valve 10 in a refrigeration cycle of the refrigerator, closes the thermosiphon suppression valve at the time of the equipment off or F cycle operation, and opens the thermosiphon suppression valve during the RF cycle operation. As a result, the thermosiphon phenomenon can be suppressed.
이제까지 본 발명에 대하여 그 바람직한 실시예를 중심으로 살펴보았으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자는 본 발명의 본질적 기술 범위 내에서 상기 본 발명의 상세한 설명과 다른 형태의 실시예들을 구현할 수 있을 것이다. 여기서 본 발명의 본질적 기술 범위는 특허청구범위에 나타나 있으며, 그와 동등한 범위 내에 있는 모든 차이점은 본 발명에 포함된 것으로 해석되어야 할 것이다.So far, the present invention has been described with reference to the preferred embodiments, and those skilled in the art to which the present invention pertains to the detailed description of the present invention and other forms of embodiments within the essential technical scope of the present invention. Could be implemented. Here, the essential technical scope of the present invention is shown in the claims, and all differences within the equivalent range will be construed as being included in the present invention.
이상에서와 같이, 본 발명은 냉장고용 냉동사이클의 구조를 개선하여, 냉동사이클의 서머사이펀 현상을 억제시킬 수 있도록 한 것으로서, 다음과 같은 효과가 있다.As described above, the present invention is to improve the structure of the refrigeration cycle for refrigerators, to suppress the thermosiphon phenomenon of the refrigeration cycle, the following effects.
서머사이펀 현상으로 나타났던 종래의 문제인 냉동실 온도가 설정온도보다 높게 올라가고 냉장실 온도가 설정온도보다 낮게되는 문제를 해결하게 되어, 냉동실 온도 및 냉장실 온도를 최적으로 유지시킬 수 있게 된다.Solving the problem that the freezer compartment temperature is higher than the set temperature and the refrigerator compartment temperature is lower than the set temperature, which is a conventional problem that appeared as a thermosiphon phenomenon, it is possible to optimally maintain the freezer compartment temperature and the refrigerator compartment temperature.
또한, 서머사이펀 현상으로 불필요한 전력을 소비하지 않아도 냉동실 온도 및 냉장실 온도를 최적화시킬 수 있으므로, 소비전력을 저감시키는 효과가 있다.In addition, since the thermosiphon phenomenon does not consume unnecessary power, the freezer compartment temperature and the refrigerating compartment temperature can be optimized, thereby reducing power consumption.
