Abstract

본 발명은 냉동기의 냉매 순환량 조절 장치에 관한 것으로, 종래에는 어큐뮤레이터가 압축기의 액 압축 방지와 부하에 대응하여 필요로 하는 냉매량 조절 기능은 제대로 수행하지만, 부하가 작을 경우 어큐뮤레이터에 고여 있는 액 냉매를 적절히 활용하지 못하여 효율이 저하됨은 물론 압축기 기동시 많은 냉매가 압축기로 유입되어 초기 입력이 높아짐에 따라 소비 전력이 상승의 원인이 되는 문제점이 있었다. 이러한 문제점을 개선하기 위하여 본 발명은 냉동 싸이클에서 단속 운전시 냉매를 보조 어큐뮤레이터에 저장한 후 압축기 기동시 증발기로 궤환시킴에 의해 많은 냉매의 유입으로 인한 초기 입력 상승을 방지하도록 창안한 것으로, 본 발명은 초기 기동시 어큐뮤레이터로부터 압축기로 많은 양의 액 냉매 유입을 방지하여 초기 입력 상승분을 제거할 수 있고, 또한, 보조 어큐뮤레이터로부터 증발기로 액 냉매가 궤환되어 기동 후 응축기로부터 증발기로 액 냉매가 유입되는 소정 시간동안 냉각 작용을 수행하게 된다. 따라서, 본 발명은 압축기 기동시 초기 입력 저감시킴과 아울러 냉기 지연에 따른 손실을 제거하여 냉동 싸이클의 효율을 극대화함에 의해 소비 전력을 저감시킬 수 있다.The present invention relates to an apparatus for controlling a refrigerant circulation amount of a refrigerator. In the related art, the accumulator performs a function of preventing a compressor from compressing liquid and adjusting a refrigerant amount required in response to a load. However, when the load is small, the accumulator accumulates in the accumulator. The efficiency of the liquid refrigerant is not properly utilized, as well as a large amount of refrigerant is introduced into the compressor when starting the compressor, there is a problem that the power consumption increases as the initial input is increased. In order to solve this problem, the present invention is to prevent the initial input rise due to the introduction of a large amount of refrigerant by storing the refrigerant in the auxiliary accumulator during the intermittent operation in the refrigeration cycle and then returning to the evaporator when the compressor is started, The present invention can prevent the inflow of a large amount of liquid refrigerant from the accumulator to the compressor during the initial startup to remove the initial input rise, and also the liquid refrigerant is fed back from the auxiliary accumulator to the evaporator to start the condenser from the condenser to the evaporator. The cooling operation is performed for a predetermined time while the liquid refrigerant is introduced. Accordingly, the present invention can reduce power consumption by maximizing the efficiency of the refrigeration cycle by reducing the initial input at the start of the compressor and eliminating the loss due to the cold air delay.
