And to an apparatus.
일반적으로 냉장고의 냉동사이클은 도 1에 도시한 바와 같이, 증발기에서 증발한 기체냉매를 흡수하여 이를 고온고압으로 압축하는 압축기(1)와, 상기 압축기(1)에서 고온고압으로 압축된 냉매를 공기중에 방열하여 액화시키는 응축기(2)와, 상기 응축기에서 유입된 액체 냉매를 감압하는 모세관(3)과, 상기 모세관(3)을 통과한 저온저압의 액냉매를 증발시켜 고내를 냉각시키는 증발기(4)로 구성되어 있다.In general, the refrigeration cycle of the refrigerator as shown in Figure 1, the compressor (1) for absorbing the gas refrigerant evaporated in the evaporator and compresses it to high temperature and high pressure, and the refrigerant compressed to high temperature and high pressure in the compressor (1) A condenser 2 for liquefying and releasing heat in the air, a capillary tube 3 for depressurizing the liquid refrigerant introduced from the condenser, and an evaporator 4 for cooling the inside of the refrigerator by evaporating the low temperature and low pressure liquid refrigerant passing through the capillary tube 3. It consists of).
상기 압축기(1)와 응축기(2) 사이에는 토출관(5)이 수회 절곡형성되어 있고, 상기 응축기(2)와 모세관(3) 사이에는 하트라인 파이프(6)와, 드라이어(7)가 연결설치되어 있다.The discharge tube 5 is bent several times between the compressor 1 and the condenser 2, and the heart line pipe 6 and the dryer 7 are connected between the condenser 2 and the capillary tube 3. It is installed.
이와 같이 구성되어 있는 냉동사이클은 압축기(1)에서 압축된 냉매가 응축기(2)에서 액화되어 전량이 하트라인 파이프(6)를 통과하게 되는데, 이때 하트라인 파이프(6)에서는 냉장고에 이슬이 맺히지 않은 정도의 열량이 항시 공급된다.In the refrigeration cycle configured as described above, the refrigerant compressed in the compressor (1) is liquefied in the condenser (2) so that the entire amount passes through the heartline pipe (6), in which the dew condensation on the refrigerator in the heartline pipe (6) Not enough calories are always supplied.
그러나 고습상태의 냉장고에서 이슬맺힘의 발생을 방지하기 위하여 항시 공급되는 공급열은 냉장고가 고습상태가 아닌 건조상태에서도 동일하게 고내로 공급되므로, 냉장고의 효율을 저하시키는 문제점으로 작용되는 것이었다.However, the supply heat is always supplied in order to prevent the occurrence of dew condensation in the refrigerator in a high humidity state, so that the refrigerator is supplied in the same state even in a dry state instead of a high humidity state, thereby reducing the efficiency of the refrigerator.

If the humidity is low, the amount of refrigerant passing through the heart line pipe is increased by opening the refrigerant flow path of the capillary side of the refrigerant flow control valve. Provided is a method for controlling a refrigeration cycle of a refrigerator comprising a step of adjusting the pressure.
이러한 냉장고의 냉동사이클 제어방법을 구현하기 위한 냉장고의 냉동사이클 장치를 첨부도면에 도시한 일실시예에 의거하여 보다 상세하게 설명한다.The refrigeration cycle apparatus of the refrigerator for implementing the refrigeration cycle control method of the refrigerator will be described in more detail based on an embodiment shown in the accompanying drawings.
본 발명에 의한 냉장고의 냉동사이클 장치는 응축기(2)와 모세관(3) 사이에 구비되는 하트라인 파이프(6)의 입구에는 냉매량 조절밸브인 3웨이 밸브(3Way Valve)(11)를 설치하고, 출구하는 3웨이 파이프(3Way Pipe)(12)를 설치하며, 상기 냉매량 조절밸브(11)의 입구측에는 고내의 습도량을 감지하는 습도센서(13)를 연결설치한 것이다.Refrigeration cycle device of the refrigerator according to the present invention is installed at the inlet of the heart line pipe (6) provided between the condenser (2) and the capillary tube (3) is provided with a three-way valve (3 Way Valve) 11, a refrigerant amount control valve, A three-way pipe 12 is installed to the outlet, and a humidity sensor 13 that detects the humidity in the refrigerator is installed at the inlet side of the refrigerant amount control valve 11.
본 발명에 의한 냉동사이클 장치에서 압축기(1), 응축기(2), 모세관(3) 및 증발기(4)의 구성을 갖는 것은 일반적인 냉동사이클 장치와 동일하다.In the refrigeration cycle apparatus according to the present invention having the configuration of the compressor (1), the condenser (2), the capillary tube (3) and the evaporator (4) is the same as the general refrigeration cycle apparatus.
이와 같이 구성되어 있는 본 발명에 의한 냉장고의 냉동사이클 장치의 작용을 설명하면, 고내를 냉각한 저온저압의 기체 냉매가 압축기(1)로 유입되면, 압축기(1)에서 이러한 기체 냉매를 압축하여 고온고압의 기체 냉매로 만들어 응축기(2)로 보내고, 응축기(2)에서는 공기 중에서 방열하여 중온고압의 액체로 만들게 된다. 이와 같이 된 중온고압의 액체 냉매는 모세관(3)으로 보내지기 전에 하트라인 파이프(6)를 거치게 되는데, 이때 하트라인 파이프(6)의 입구에 설치된 냉매량 조절밸브(11)는 고내에 설치된 습도센서(13)에 의해 냉매의 양을 조절하게 된다.Referring to the operation of the refrigeration cycle apparatus of the refrigerator according to the present invention configured as described above, when the low-temperature low-pressure gas refrigerant to cool the inside flows into the compressor (1), the compressor (1) compresses the gas refrigerant to high temperature It is made of a high-pressure gas refrigerant to be sent to the condenser (2), the heat in the condenser (2) is made into a liquid of medium temperature and high pressure. The liquid refrigerant of the medium temperature and high pressure is passed through the heartline pipe 6 before being sent to the capillary tube 3, where the refrigerant amount control valve 11 installed at the inlet of the heartline pipe 6 is a humidity sensor installed in the chamber. The amount of the coolant is controlled by (13).
이를 부연하면, 도 3에서 보는 바와 같이, 상기 냉매량 조절밸브(11)는 하트라인 파이프측 냉매유로(11a)와, 모세관측 냉매유로(11b)로 구분되어 있어 고내의 습도가 많은 경우에는 하트라인 파이프측 냉매유로(11a)를 더 많이 개방하게 되며, 이때 고내의 습도량이 커지는 만큼 냉매유로는 더 크게 개방된다.3, the refrigerant amount control valve 11 is divided into a heart line pipe side refrigerant passage 11 a and a capillary side refrigerant passage 11 b. The pipe side refrigerant passage 11a is opened more, and the refrigerant passage is opened larger as the amount of humidity in the air increases.
또한, 고내가 건조한 경우에는 습도센서(13)가 이를 감지하여 모세관측 냉매유로(11b)를 더 크게 개방함으로써 응축기(2)를 통과한 냉매가 하트라인 파이프(6)를 거치지 않고 바로 모세관(3)측으로 유입되도록 한다.In addition, when the inside of the refrigerator is dry, the humidity sensor 13 detects this and opens the capillary-side refrigerant passage 11b larger, so that the refrigerant passing through the condenser 2 does not pass through the heartline pipe 6, but directly into the capillary tube 3. To flow to the side.
이상과 같이 본 발명에 의한 냉장고의 냉동사이클 장치는 고내의 습도량을 감지하여 이에 따라 하트라인 파이프를 거치는 냉매의 양을 조절함으로써 불필요한 열량이 고내로 유입되는 것을 방지함으로써 냉장고의 효율을 극대화시키는 효과가 있으며, 이러한 냉동사이클 제어방법 및 장치는 냉장고에만 국한되어 사용되는 것이 아니라 본 발명의 기술사상의 범위 내에서 냉동기기 전반에 적용가능하다.As described above, the refrigerator's refrigeration cycle apparatus according to the present invention senses the amount of humidity in the refrigerator and adjusts the amount of refrigerant passing through the heartline pipe accordingly, thereby preventing unnecessary heat from being introduced into the refrigerator, thereby maximizing the efficiency of the refrigerator. In addition, such a refrigeration cycle control method and apparatus is not limited to the refrigerator, but can be applied to the entire refrigerator within the spirit of the present invention.
