Abstract:
(EN) The present invention relates to a refrigerator and a control method therefor and, more specifically, to a technology for preventing the temperature of a storage chamber from increasing by defrosting heat generated during a defrosting process, and for performing efficient refrigeration and freezing operations. The refrigerator according to one embodiment comprises: a main body; a first storage chamber and a second storage chamber which are provided inside the main body; a first evaporator provided in the first storage chamber so as to generate cold air; a second evaporator provided in the second storage chamber so as to generate cold air; a switching valve for supplying a refrigerant to the first evaporator and/or the second evaporator; and a control unit for generating a control signal, which controls the switching valve so as to distribute, according to a predetermined standard, the refrigerant supplied to the first evaporator and the refrigerant supplied to the second evaporator, and lowering the temperature of the first storage chamber and the second storage chamber to a predetermined temperature on the basis of the generated control signal.
(FR) La présente invention concerne un réfrigérateur et son procédé de commande et, plus spécifiquement, une technologie pour empêcher la température d'une chambre de stockage d'augmenter par la chaleur de dégivrage générée pendant un processus de dégivrage, et pour effectuer des opérations de réfrigération et de congélation efficaces. Le réfrigérateur selon un mode de réalisation comprend : un corps principal; une première chambre de stockage et une seconde chambre de stockage qui sont disposées à l'intérieur du corps principal; un premier évaporateur disposé dans la première chambre de stockage de façon à générer de l'air froid; un second évaporateur disposé dans la seconde chambre de stockage de façon à générer de l'air froid; une vanne de commutation pour fournir un fluide frigorigène au premier évaporateur et/ou au second évaporateur; et une unité de commande pour générer un signal de commande, qui commande la vanne de commutation de façon à distribuer, selon une norme prédéterminée, le fluide frigorigène fourni au premier évaporateur et le fluide frigorigène fourni au second évaporateur, et à abaisser la température de la première chambre de stockage et de la seconde chambre de stockage à une température prédéterminée sur la base du signal de commande généré.
(KO) 냉장고 및 그 제어방법에 관한 것으로, 보다 상세하게는 제상과정에서 발생하는 제상열에 의해 저장실의 온도가 상승하는 것을 방지하고, 효율적인 냉장 및 냉동 운전을 수행하기 위한 기술에 관한 것이다. 일 실시예에 따른 냉장고는, 본체, 본체 내부에 마련되는 제 1저장실 및 제 2저장실, 제 1저장실에 마련되어 냉기를 생성하는 제 1증발기, 제 2저장실에 마련되어 냉기를 생성하는 제 2증발기, 제 1증발기 및 제 2증발기 중 적어도 하나로 냉매를 공급하는 전환 밸브 및 제 1증발기로 공급되는 냉매 및 제 2증발기로 공급되는 냉매가 미리 정해진 기준에 따라 분배되도록 전환 밸브를 제어하는 제어 신호를 생성하고, 생성된 제어 신호에 기초하여 제 1저장실 및 제 2저장실의 온도를 미리 정해진 온도로 낮추는 제어부를 포함한다.
