Abstract

본 발명은 냉장고의 냉장 및 냉동사이클 진행제어장치 및 제어방법에 관한 것으로, 특히 두개의 증발기를 구성히여 각각의 증발기의 냉매의 흐름을 제어하고자 한 것이다.The present invention relates to a refrigeration and refrigeration cycle progress control device and control method of the refrigerator, and in particular to configure the two evaporators to control the flow of the refrigerant of each evaporator.

종래 하나의 증발기를 갖고 냉장 및 냉동사이클을 이루는 냉장고는 하나의 증발기로 -18℃의 냉기를 냉장실 및 냉동실에 유입시키므로, 냉장실의 유지온도가 +3℃근처임에도 불구하고 필요이상의 냉각된 냉기가 공급되므로서 소비전력이 증가하는 문제점이 발생하고, 이와 같은 문제점을 해결하기 위하여 냉장실 및 냉동실 각각에 증발기를 구성하여 냉장실과 냉동실에 각각의 유지온도에 맞는 냉기를 유입시키고자 하는 냉장고가 구상된 바, 그러나 이와 같은 냉장고는 냉장실에 과대부하가 걸렸을 때나, 냉동실에 과대부하가 걸렸을 때와 같은 악조건에서 냉동사이클의 운전상식이 명확하지 않고, 냉장실 및 냉동실을 목표온도로 유지시키기 위한 제어방법에 없으며 반드시 이단압축기를 사용하여야 하는 문제점이 있었다.Conventionally, a refrigerator having one evaporator and forming a refrigeration and freezing cycle introduces cold air of -18 ° C into the refrigerator and freezer with one evaporator. As a result, the power consumption increases, and in order to solve such a problem, a refrigerator is designed to introduce cold air for each maintenance temperature by forming an evaporator in each of the refrigerator compartment and the freezer compartment. However, such refrigerators are unclear in the refrigeration cycle under unfavorable conditions such as when the refrigerating chamber is overloaded or when the freezer is overloaded, and there is no control method to maintain the refrigerator compartment and the freezer at the target temperature. There was a problem that a compressor must be used.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 하나의 압축기와 두개의 증발기를 구성하여 냉장실 및 냉동실의 온도에 따라 두개의 삼방밸브의 방향을 조절하여 각기 다른 냉동 및 냉장사이클을 구성시켜 냉매의 흐름을 제어하여 주므로서 냉장고의 소비전력을 감소시킬 수 있도록 한 것이다.The present invention comprises a compressor and two evaporators to solve the conventional problems by adjusting the direction of the two three-way valve according to the temperature of the refrigerator compartment and the freezer compartment to configure different refrigeration and refrigerating cycles of the refrigerant flow By controlling the power consumption of the refrigerator can be reduced.
