Abstract: The present invention relates to a refrigerator and a method for controlling a refrigerator, and more particularly to a refrigerator and a method for controlling a refrigerator in which unnecessary operation of a compressor is prevented for saving power consumption of the refrigerator. The refrigerator includes a compressor, a refrigerating chamber evaporator and a freezing chamber evaporator connected to the compressor, a refrigerant valve for guiding refrigerant to the refrigerating chamber evaporator or the freezing chamber evaporator, and a control unit for controlling the refrigerant valve such that the refrigerant valve blocks or introduces the refrigerant to cause an inside pressure of the freezing chamber evaporator to be elevated higher than an inside pressure of the refrigerating chamber evaporator during evaporation at the refrigerating chamber evaporator for the compressor to draw in the refrigerant remained in the freezing chamber evaporator which did not evaporate.

Abstract: A refrigerator includes a refrigerating compartment, a freezing compartment, and a switching compartment to store food items. Various elements are provided to maintain the three compartments at selected target temperatures. A heater and/or a light source may be provided to rapidly heat the switching compartment when the switching compartment is being changed from a freezing operation to a refrigerating operation.

Abstract: A refrigerator control method is disclosed which ensures efficient operation of a compressor. To control a refrigerator including a compressor, a first evaporator and a second evaporator connected to the compressor, and a refrigerant control valve that controls introduction of a refrigerant into the first evaporator and the second evaporator, the refrigerator control method includes operating the compressor, and controlling the opening and closing of the refrigerant control valve, to reduce not only consumption of electricity by the compressor, but also a pressure difference between an entrance and an exit of the compressor upon starting of the compressor.

Abstract: A refrigerator control method is provided that may efficiently perform a defrosting operation. The method includes performing a normal operation of a refrigerating storage room and a normal operation of a freezing storage room selectively or simultaneously, setting a variable defrosting period, which is varied according to set parameters including the relative humidity of external air, and performing a defrosting operation based on the set defrosting period.

Abstract: A radiating apparatus of a built-in refrigerator includes an airflow guide that separates a condenser from a blower fan in order to prevent a cool air and a hot air from mixing together, thereby increasing an efficiency of the built-in refrigerator.

Abstract: A refrigerator is disclosed. A freezing chamber evaporator and a cooling chamber evaporator are installed at an inner side of a ceiling surface of a freezing chamber and a cooling chamber. Accordingly, the freezing chamber and the cooling chamber have deeper depths thus to have large available capacities, thereby freshly receiving a large amount of food items. Furthermore, a cool air channel is formed at the freezing chamber door and the cooling chamber door so as to be connected to a cool air channel of the ceiling surface. Accordingly, a temperature difference between an inner space and a door basket does not occur, thereby storing food or beverage items received in the door basket in a fresh condition.

Abstract: A refrigerator is disclosed. A freezing chamber evaporator and a chilling chamber evaporator are installed at an inner side of a partition wall that partitions a freezing chamber and a chilling chamber from each other. Accordingly, the freezing chamber and the chilling chamber have deep depths thus to have large available capacities, thereby freshly receiving a large amount of food items. Furthermore, a cool air channel is formed at the freezing chamber door and the chilling chamber door so as to be connected to a cool air channel of the partition wall. Accordingly, a temperature difference between an inner space and a door basket does not occur, thereby storing food or beverage items received in the door basket with a fresh state.

Abstract: Provided is a radiating apparatus of a built-in refrigerator that can improve heat radiation in a machine room of the refrigerator installed in a built-in cabinet. The radiating apparatus includes: a refrigerator body installed in a built-in cabinet; a machine room disposed at a rear lower side of the refrigerator body; a compressor installed at one side of the machine room; a condenser and a blower fan installed at the other side of the machine room; and an airflow guide member installed between the blower fan and the condenser, for guiding a suction of an external air toward the other side of the machine room and guiding a discharge of an air that has exchanged heat in the other side of the machine room.
