Disclosed are a multi-duct assembly, a refrigerator which includes the multi-duct assembly, and a method of controlling the refrigerator. The multi-duct assembly has a new structure for overcoming limitations of a related art. The multi-duct assembly may adjust opening states and sizes of cold air outlets formed at a multi-duct panel by moving a variable duct panel disposed on a rear surface of the multi-duct panel upward or downward.

Multi-duct assembly, refrigerator including the multi-duct assembly, and method of controlling the refrigerator

The present invention relates to a refrigerator having a defrosting device, the refrigerator comprising: a refrigerator main body; an evaporator provided in the refrigerator main body; a defrosting heater provided at the lower side of the evaporator so as to emit heat when a power source is applied; and a heat pipe for transferring heat to the evaporator, one side of the heat pipe being arranged so as to be able to transfer heat to one side of the defrosting heater, and the other side of the heater pipe extending to the upper side along the vertical direction of the evaporator. Thereby, the present invention can shorten defrosting time and reduce power consumption.

Refrigerator having defrosting device

A method for controlling temperature of a refrigerator including a main body having at least first and second adiabatic spaces; a refrigerant compression cycle device including an evaporator, a compressor, a condenser, and an expander installed within the main body; and a heating unit transferring heat of a refrigerant discharged from the condenser to air in the second adiabatic space, includes: measuring an internal temperature of the second adiabatic space; bypassing the refrigerant discharged from the condenser to the second adiabatic space when the measured internal temperature of the second adiabatic space is lower than a lower limit value of a pre-set temperature range; measuring ambient temperature of the condenser; and controlling an operation of a condenser cooling fan according to the ambient temperature of the condenser to maintain the refrigerant that passes through the interior of the condenser at a certain temperature or higher.
