Description
본 발명은 냉장고와 같은 냉동사이클을 이용하는 냉동기기에 있어서, 특히 응축기와 모세관 사이에 구비되는 하트라인 파이프를 통과하는 냉매의 양을 조절하여 고내의 습도여부에 따라 조절하도록 한 냉장고의 냉동사이클 제어방법 및 장치에 관한 것이다.The present invention relates to a refrigeration cycle control method for a refrigerator in which the amount of refrigerant passing through a heart line pipe provided between a condenser and a capillary is controlled to adjust the humidity depending on the humidity in a refrigerator, And apparatus.
일반적으로 냉장고의 냉동사이클은 제1도에 도시한 바와 같이, 증발기에서 증발한 기체 냉매를 흡수하여 이를 고온고압으로 압축하는 압축기(1)와, 상기 압축기(1)에서 고압으로 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.Generally, as shown in FIG. 1, the refrigeration cycle of a refrigerator includes a compressor 1 for absorbing gas refrigerant evaporated in an evaporator and compressing it to a high temperature and a high pressure, A capillary 3 for decompressing the liquid refrigerant introduced from the condenser 3 and an evaporator 4 for evaporating the low temperature and low pressure liquid refrigerant passing through the capillary 3 to cool the inside of the condenser 2 ).
상기 압축기(1)와 응축기(2) 사이에는 토출관(5)이 수 회 절곡형성되어 있고, 상기 응축기(2)와 모세관(3) 사이에는 하트라인 파이프(6)와, 드라이어(7)가 연결설치되어 있다.A discharge pipe 5 is bent several times between the compressor 1 and the condenser 2. Between the condenser 2 and the capillary 3 is connected a heart line pipe 6 and a dryer 7 Connected 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 refrigerating cycle thus constituted, the refrigerant compressed in the compressor 1 is liquefied in the condenser 2 and the whole amount passes through the heart line pipe 6. At this time, in the heart line pipe 6, dew is formed in the refrigerator A certain amount of heat is 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, in order to prevent the occurrence of dew condensation in the refrigerator in a high humidity state, the supplied heat always supplied to the inside of the refrigerator in a dry state, not in a high humidity state.
이러한 문제점을 감안하여 안출한 본 발명의 목적은 고내에서 고습상태와 건조상태의 여부에 따라 증발기로 유입되는 냉매에 공급되는 열량을 조절하도록 할 수 있는 냉장고의 냉동사이클 제어방법 및 장치를 제공함에 있다.It is an object of the present invention to provide a method and an apparatus for controlling a refrigeration cycle of a refrigerator that can control a quantity of heat supplied to a refrigerant flowing into an evaporator depending on whether the refrigerant is in a high humidity state or in a dry state .

When the amount of humidity is small, the capillary flow side refrigerant flow path of the refrigerant flow control valve is largely opened, And controlling the refrigeration cycle of the refrigerator.
이러한 냉장고의 냉동사이클 제어방법을 구현하기 위한 냉장고의 냉동사이클 장치를 첨부도면에 도시한 일실시예에 의거하여 보다 상세하게 설명한다.A refrigeration cycle apparatus of a refrigerator for implementing a refrigeration cycle control method for such a refrigerator will be described in more detail with reference to 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, 출구에는 3웨이 파이프(3 Way Pipe)(12)를 설치하며, 상기 냉매량 조절밸브(11)의 입구측에는 고내의 습도량을 감지하는 습도센서(13)를 연결설치한 것이다.The refrigeration cycle apparatus for a refrigerator according to the present invention is provided with a 3-way valve (11) as a refrigerant amount control valve at the inlet of a heart line pipe (6) provided between a condenser (2) Way pipe (12) is installed at the outlet of the evaporator, and a humidity sensor (13) for detecting the amount of humidity in the hearth is connected to the inlet side of the refrigerant quantity 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, the compressor 1, the condenser 2, the capillary tube 3, and the evaporator 4 are the same as those of a 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 의한 냉매의 양을 조절하게 된다.When the low-temperature low-pressure gaseous refrigerant cooled in the furnace flows into the compressor 1, the gaseous refrigerant is compressed by the compressor 1 and is supplied to the high-temperature Pressure gas refrigerant and sent to the condenser 2, and in the condenser 2, the refrigerant is radiated in the air to be a medium-temperature high-pressure liquid. The liquid refrigerant at the intermediate temperature and high pressure is passed through the heart line pipe 6 before being sent to the capillary tube 3. The refrigerant flow rate control valve 11 provided at the inlet of the heart line pipe 6 is connected to a humidity sensor The amount of the refrigerant by the refrigerant circuit 13 is controlled.
이를 부연하면, 제3도에서 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 refrigerant flow path 11a on the side of the heart line pipe and a refrigerant flow path 11b on the capillary side, and when the humidity is high, The refrigerant flow path 11a on the line pipe side is opened more and the refrigerant flow path is opened to a greater extent as the amount of humidity in the hearth 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.The humidity sensor 13 senses this and opens the capillary-side refrigerant passage 11b to open the capillary-side refrigerant passage 11b so that the refrigerant that has passed through the condenser 2 flows directly through the capillary tube 3 .
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 refrigeration cycle device of the refrigerator according to the present invention detects the amount of humidity in the hearth and accordingly controls the amount of refrigerant passing through the heart line pipe, thereby preventing unnecessary heat from flowing into the hearth, thereby maximizing the efficiency of the refrigerator The refrigeration cycle control method and apparatus are not limited to the refrigerator but are applicable to the refrigeration apparatus within the scope of the technical idea of the present invention.
