본 발명은 소음저감을 위한 냉동사이클을 구비한 복합냉장고에 관한 것으로서, 더욱 상세하게는 압축기에서 고온 고압으로 토출되는 냉매의 흐름량을 조절함으로써 냉매배관의 급격한 압력 변화로 인한 기동 소음을 줄일 수 있는 소음저감을 위한 냉동사이클을 구비한 복합냉장고에 관한 것이다.
The present invention relates to a complex refrigerator having a refrigerating cycle for reducing noise, and more particularly, a noise that can reduce starting noise due to a sudden pressure change in a refrigerant pipe by adjusting a flow rate of a refrigerant discharged at high temperature and high pressure from a compressor. It relates to a composite refrigerator having a refrigeration cycle for reduction.

일반적으로 냉장고에는 냉동실 및 냉장실에 공급할 냉기를 얻기 위해 냉매를 순환시키는 장치가 구비되어 있으며, 그 냉매를 순환시키기 위하여 냉매를 고도로 압축 이송시키는 압축기가 사용된다. 이러한 압축기는 강력한 전동기를 동력원으로 하는데 그 운전 중에 상당한 기계적 및 유체적 소음이 발생되어 사용자의 불쾌감을 초래하는가 하면, 그 소음이 냉장고의 본체와 각 부품으로 전달됨으로써 그 소음을 증폭시키는 것은 물론 그 수명을 단축시킨다. 따라서 냉장고의 정숙운전을 위해 소음을 억제할 필요가 있는 것이다.In general, a refrigerator is provided with a device for circulating a refrigerant to obtain cold air to be supplied to the freezer compartment and the refrigerating compartment, and a compressor for highly compressively transporting the refrigerant is used to circulate the refrigerant.

Therefore, it is necessary to suppress the noise for quiet operation of the refrigerator.

It is introduced again, at this time via a muffler installed in the suction pipe.

머플러는 압축기가 작동될 때 발생되는 소음이 그에 연결되어 있는 토출관과 흡입관을 통해 냉장고 본체로 전달되는데, 이를 방지하기 위하여 그 내부를 흐르는 냉매가 팽창 및 압축되게 하는 과정을 통하여 그 소음을 완화시키는 것이다.The muffler transmits the noise generated when the compressor is operated to the refrigerator main body through the discharge pipe and the suction pipe connected to the muffler. In order to prevent this, the muffler reduces the noise through the process of allowing the refrigerant flowing therein to expand and compress. will be.

기존에는 저장고의 기동 소음 개선할 수 있도록 압력 제어를 위해 압축기 토출배관에 머플러가 장착되었지만, 기동 소음 개선에 한계가 있고, 압력 강하 실패시 기동 소음이 증가하는 문제점이 있다.Conventionally, a muffler is installed in the compressor discharge pipe for pressure control so as to improve the starting noise of the storage, but there is a limit in improving the starting noise, and there is a problem in that the starting noise increases when the pressure drop fails.

도 1은 본 발명의 일 실시예에 따른 복합냉장고의 냉동사이클을 보인 구성도이다.
1 is a block diagram showing a refrigerating cycle of the composite refrigerator according to an embodiment of the present invention.

도 1을 참조하면, 본 발명의 일 실시예에 따른 복합냉장고용 냉동사이클은 압축기(10), 응축기(20), 팽창밸브(30), 증발기(40), 밸브부재(100) 및 제어부(200)를 포함한다.Referring to FIG. 1, a refrigeration cycle for a multiple refrigerator according to an embodiment of the present invention includes a compressor 10, a condenser 20, an expansion valve 30, an evaporator 40, a valve member 100, and a controller 200. ).

압축기(10)는 저온저압의 기체냉매를 고온고압의 기체냉매로 변화시키는 역할을 하고, 응축기(20)는 압축기(10)에서 변화된 고온 고압의 기체냉매를 상온고압의 액체냉매로 변화시키는 역할을 한다.The compressor 10 serves to change the gas refrigerant of low temperature and low pressure into a gas refrigerant of high temperature and high pressure, and the condenser 20 changes the gas refrigerant of high temperature and high pressure changed in the compressor 10 into a liquid refrigerant of room temperature and high pressure. do.

그리고, 팽창밸브(30)는 응축기(20)를 거친 상온고압의 액체냉매를 저온저압의 액체냉매로 변화시키는 역할을 하고, 증발기(40)는 팽창밸브(30)에서 변화된 저온저압의 액체냉매를 기체상태로 변화시키면서 외부의 열을 흡수하는 역할을 한다.In addition, the expansion valve 30 serves to change the liquid refrigerant of room temperature and high pressure through the condenser 20 into a liquid refrigerant of low temperature and low pressure, and the evaporator 40 converts the liquid refrigerant of low temperature and low pressure changed from the expansion valve 30. It absorbs external heat while changing to gaseous state.

이와 같이 구성된 복합냉장고의 냉동사이클을 간략히 설명하면, 우선 압축기(10)에서 프레온 가스 등과 같은 냉매가 고온고압의 상태로 압축되어 제 1냉매배관(1)과 제 2냉매배관(2)으로 공급된다. 냉매배관(1,2)은 압축기(10)와 응축기(20)를 연결한다. 그래서, 고온고압의 냉매는 응축기(20)로 유입된다. 그래서, 고온고압의 냉매는 응축기(20)를 거치게 되면서 저온상태로 냉각됨에 따라 상온고압의 액체냉매로 상변화하게 된다.Referring briefly to the refrigeration cycle of the composite refrigerator configured as described above, first, the refrigerant such as a freon gas is compressed in a state of high temperature and high pressure in the compressor 10 is supplied to the first refrigerant pipe (1) and the second refrigerant pipe (2). . The refrigerant pipes 1 and 2 connect the compressor 10 and the condenser 20. Thus, the high temperature and high pressure refrigerant flows into the condenser 20. Therefore, the high temperature and high pressure refrigerant is phase-changed into a liquid refrigerant of room temperature and high pressure as it is cooled to a low temperature state while passing through the condenser 20.

이 후, 응축기(20)를 거친 액체냉매는 제 3냉매배관(3)을 통해 팽창밸브(30)로 유입된다. 즉, 저온 고압의 냉매는 모세관 형태로 되어 있는 팽창밸브(30)에 유입된다. 팽창밸브(30)에서 냉매는 고압에서 저압으로 급격히 단열 팽창되어 저온 저압 상태로 되며 약 -30 ℃ 정도로 온도가 저하된다.Thereafter, the liquid refrigerant passing through the condenser 20 is introduced into the expansion valve 30 through the third refrigerant pipe 3. That is, the low temperature and high pressure refrigerant flows into the expansion valve 30 in the form of a capillary tube. In the expansion valve 30, the refrigerant is rapidly adiabaticly expanded from high pressure to low pressure to a low temperature low pressure state, and the temperature drops to about -30 ° C.

팽창밸브(30)에 의해 저온저압 상태로 된 액체냉매는 제 4냉매배관(4)을 통해 증발기(40)로 유입된다. 증발기(40)로 유입된 액체냉매는 급격하게 기화되어 주위의 공기로부터 온도를 빼앗음으로써 복합냉장고의 냉동실 및 냉장실로 공급되는 냉기를 발생시키게 된다. The liquid refrigerant in a low temperature low pressure state by the expansion valve 30 is introduced into the evaporator 40 through the fourth refrigerant pipe (4). The liquid refrigerant introduced into the evaporator 40 is rapidly vaporized to take temperature from the surrounding air, thereby generating cold air supplied to the freezing compartment and the refrigerating compartment of the combined refrigerator.

증발기(40)를 거친 기체냉매는 제 5냉매배관(5)을 통해 압축기(10)로 회수된다.The gas refrigerant passing through the evaporator 40 is recovered to the compressor 10 through the fifth refrigerant pipe (5).

한편, 압축기(10)와 응축기(20) 사이에는 냉매의 흐름을 단속하기 위해 밸브부재(100)가 구비된다. 즉, 밸브부재(100)는 압축기(10)의 냉매 토출측에 구비되어 냉매의 흐름을 단속하는 역할을 한다. 다시 말해서, 제 1냉매배관(1)은 압축기(10)와 밸브부재(100)를 연결하고, 제 2냉매배관(2)은 밸브부재(100)와 응축기(20)를 연결한다. 이에 따라, 압축기(10)를 통과하며 고온 고압의 기체 상태인 냉매는 제 1냉매배관(1)을 통해 유동하게 되며, 밸브부재(100)의 개방시 제 2냉매배관(2)을 통해 응축기(20)로 유입된다.On the other hand, the valve member 100 is provided between the compressor 10 and the condenser 20 to control the flow of the refrigerant. That is, the valve member 100 is provided on the refrigerant discharge side of the compressor 10 to serve to interrupt the flow of the refrigerant. In other words, the first refrigerant pipe 1 connects the compressor 10 and the valve member 100, and the second refrigerant pipe 2 connects the valve member 100 and the condenser 20. Accordingly, the refrigerant passing through the compressor 10 and in a gaseous state of high temperature and high pressure flows through the first refrigerant pipe 1, and when the valve member 100 is opened, a condenser (2) through the second refrigerant pipe (2). 20).

특히, 밸브부재(100)는 냉매의 역류를 막을 수 있는 종류의 밸브로 이루어짐이 바람직하다. 그리고, 밸브부재(100)는 평상시 항상 개방되어 냉동사이클을 순환하는 냉매가 평압을 유지하도록 함이 바람직하다.In particular, the valve member 100 is preferably made of a valve of the type that can prevent the back flow of the refrigerant. In addition, the valve member 100 is normally open at all times, so that the refrigerant circulating in the refrigeration cycle is preferably maintained at a flat pressure.

아울러, 냉매는 압축기(10)를 거치면서 고온 고압 상태가 된 후 제 1냉매배관(1)과 개방된 밸브부재(100)를 거친 후 제 2냉매배관(2)으로 토출된다. 그래서, 제 1냉매배관(1)과 제 2냉매배관(2)은 내부를 유동하는 냉매의 급격한 압력 상승으로 인해 기동 소음을 발생하게 된다.In addition, the refrigerant is discharged to the second refrigerant pipe (2) after passing through the first refrigerant pipe (1) and the open valve member 100 after the high temperature and high pressure state through the compressor (10). Thus, the first refrigerant pipe (1) and the second refrigerant pipe (2) generates a starting noise due to the rapid pressure rise of the refrigerant flowing through the inside.

그래서, 제어부(200)가 밸브부재(100)에 전기적으로 연결된다. 제어부(200)는 압축기(10)로부터 냉매 토출 유동압력의 변화율을 줄임으로써 기동 소음을 저감시키기 위해 밸브부재(100)가 서서히 개방되도록 제어하는 역할을 한다.Thus, the controller 200 is electrically connected to the valve member 100. The controller 200 serves to control the valve member 100 to be gradually opened to reduce the starting noise by reducing the rate of change of the refrigerant discharge flow pressure from the compressor 10.

다시 말해서, 밸브부재(100)가 평상시에 개방된 상태에서, 제어부(200)는 압축기(10)의 기동 전(前) 수 초 내에 밸브부재(100)를 닫도록 제어하고, 압축기(10)의 기동시와 함께 밸브부재(100)를 서서히 개방하도록 제어한다. 이때, '수 초'는 냉동사이클을 순환하는 냉매가 평압을 유지하도록 최대한 단시간에 밸브부재(100)가 닫힘을 의미한다.In other words, in a state where the valve member 100 is normally opened, the controller 200 controls to close the valve member 100 within a few seconds before the compressor 10 is started, and The valve member 100 is controlled to open gradually with startup. At this time, "seconds" means that the valve member 100 is closed in the shortest possible time so that the refrigerant circulating the refrigeration cycle maintains the flat pressure.

이에 따라, 압축기(10)가 운전시, 밸브부재(100)가 조금씩 개방되도록 제어됨으로써, 제 2냉매배관(2)은 내부 압력의 급격한 증가를 막게 된다. 이로 인해, 압축기(10)의 기동소음이 줄어들게 되고, 냉매는 가속화되지 않아 유음(流音)의 발생이 방지된다.Accordingly, when the compressor 10 is operated, the valve member 100 is controlled to open little by little, so that the second refrigerant pipe 2 prevents a sudden increase in the internal pressure. As a result, the starting noise of the compressor 10 is reduced, and the refrigerant is not accelerated, so that the occurrence of oil noise is prevented.

이때, 밸브부재(100)가 서서히 개방되도록 제어됨으로써, 제 1냉매배관(1)도 내부 압력의 급격한 증가를 방지할 수 있다.At this time, since the valve member 100 is controlled to be gradually opened, the first refrigerant pipe 1 may also prevent a sudden increase in the internal pressure.
