The present invention relates to a method for reducing refrigerant noise of a chest type Kim Jang-dok refrigerator which can improve the generated noise by changing a control algorithm without changing the structure of the refrigerator.
일반적으로 종래의 체스트 타입 김장독 냉장고는 운전중 압축기가 정지하면 압력 균형을 찾기 위하여 응축기 측의 고압이 어큐뮬레이터의 오리피스 홀을 통하여 빠져 나가면서 어큐뮬레이터 내부에서 기포가 발생하고, 이 기포가 터지면서 소음이 발생하는 문제점이 있었다.Generally, in the case of a conventional chest type Kim Jang-dok refrigerator, when the compressor stops during operation, the high pressure on the condenser side escapes through the accumulator's orifice hole to find the pressure balance, and bubbles are generated inside the accumulator. There was a problem.
도 1은 종래 김장독 냉장고의 냉매 절환밸브 동작 설명도를 보인 것이고, 도 2는 종래 김장독 냉장고의 좌칸 어큐뮬레이터 작용 설명도를 보인 것이다.1 is a view illustrating an operation of a refrigerant switching valve of a conventional Kim Chang-dok refrigerator, and FIG. 2 is an explanatory view of a left compartment accumulator operation of a conventional Kim Chang-dok refrigerator.

The chest type Kim Jang-dok refrigerator, which employs a conventional one comp two eva system, operates one compartment (left) compartment. When the compressor is stopped, the refrigerant switching valve 10 is switched so that one side (left) compartment passage 21 of both side (left and right) compartment passages 21 and 22 of the refrigerant passage 20 is opened. In this state, while the high-temperature high-pressure refrigerant in the condenser exits the orifice hole 33 of the one-side (left) compartment accumulator 31 having a large amount of refrigerant therein, there is a problem that noise is generated as bubbles B are generated.

도 3은 본 발명의 일 실시예가 채용되는 김장독 냉장고의 냉매 절환밸브 동작 설명도이고, 도 4는 본 발명의 일 실시예가 채용되는 김장독 냉장고의 좌,우측 칸 어큐뮬레이터 작용 설명도로서, 이에 도시한 바와 같이, 1압축기 2증발기 시스템의 체스트 타입 김장독 냉장고에 있어서, 일측 칸 운전시 압축기가 정지할 때에 냉매 절환밸브(10)를 양측 칸 통로(21),(22) 중 일측 칸 통로(21)가 닫히고 타측 칸 통로(22)가 열리도록 절환시켜 응축기 내의 고온고압냉매를 상기 타측 칸 통로(22)를 통하여 타측 칸 어큐뮬레이터(32)로 흐르도록 유도하는 것을 특징으로 하고 있다.FIG. 3 is an explanatory view of a refrigerant switching valve operation of a Kim Chang-dok refrigerator employing an embodiment of the present invention, and FIG. 4 is an explanatory view of the left and right compartment accumulators of the Kim Jang-dok refrigerator employing an embodiment of the present invention. Similarly, in the chest type Kim Chang-dok refrigerator of the one compressor two evaporator system, when the compressor stops during the operation of one compartment, the refrigerant passage valve 10 is closed in one compartment passage 21 of both compartment passages 21 and 22, It is characterized in that the other compartment passage 22 is switched to open so that the high temperature and high pressure refrigerant in the condenser flows to the other compartment accumulator 32 through the other compartment passage 22.
이와 같은 본 발명에 의한 체스트 타입 김장독 냉장고의 냉매음 저감방법은 제어장치의 마이크로 프로세서에 의해 본체에 구비된 좌,우측 칸 중 일측 칸이 운전되는지를 감지하는 단계와, 상기 일측 칸이 운전되는 중 압축기가 정지되는 지를 감지하는 단계와, 상기 압축기가 정지하는 때에 냉매 절환밸브를 양측 칸 통로(21),(22) 중 타측 칸 통로(22)가 열리도록 절환시켜 응축기 내의 고온고압냉매를 타측 칸 어큐뮬레이터(32)로 흐르도록 유도하는 단계를 포함하여 구성된다.The method for reducing the refrigerant sound of the chest type Kim Jang-dok refrigerator according to the present invention includes detecting whether one side of the left and right compartments provided in the main body is operated by a microprocessor of the control device, and the one side compartment is being operated. Detecting whether the compressor is stopped, and switching the refrigerant switching valve so that the other compartment passage 22 of the compartment passages 21 and 22 is opened when the compressor is stopped, thereby converting the high temperature and high pressure refrigerant in the condenser into the other compartment. Inducing flow to the accumulator 32.
상기한 바와 같은 본 발명의 일 실시예에 의한 체스트 타입 김장독 냉장고의 냉매음 저감방법이 채용된 체스트 타입 김장독 냉장고는 일측 칸 운전시 압축기가 정지할 때에 냉매 절환밸브(10)가 양측 칸 통로(21),(22) 중 일측 칸 통로(21)가 닫히고 타측 칸 통로(22)가 열리도록 절환되며, 이에 따라 응축기 내의 고온고압냉매가 상기 타측 칸 통로(22)를 통하여 운전되지 않아 냉매량이 적은 타측 칸 어큐뮬레이터(32)로 흐르게 되므로 기포(B)가 발생되지 않으며, 이에 따라 냉매에 의한 소음이 방지된다. 따라서, 본 발명은 통상의 체스트 타입 김장독 냉장고의 구조를변경하지 않고 제어 알고리즘을 변경하여 냉매에 의한 소음을 방지할 수 있으므로 제품의 구조적 사양을 유지하면서 성능 및 신뢰성을 향상시킬 수 있다.In the chest type gimjangdok refrigerator employing the method for reducing the refrigerant sound of the chest type gimjangdok refrigerator according to the embodiment of the present invention as described above, the refrigerant switching valve 10 is connected to both compartment passages 21 when the compressor stops during one compartment operation. One side of the compartment passage 21 is closed and the other compartment passage 22 is opened to open, so that the high temperature and high pressure refrigerant in the condenser is not operated through the other compartment passage 22 so that the amount of the refrigerant is low. Since it flows to the compartment accumulator 32, the bubble B is not generated, and noise by the refrigerant is prevented accordingly. Therefore, the present invention can prevent noise caused by the refrigerant by changing the control algorithm without changing the structure of a conventional chest type Kim Jang-dok refrigerator, thereby improving performance and reliability while maintaining structural specifications of the product.
