Refrigerator with convertible chamber and operation method thereof

A refrigerator comprising:

• 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;
• a heating unit transferring heat of a refrigerant discharged from the condenser to air in the second adiabatic space;
• a condenser cooling fan installed at the condenser to cool the condenser;
• first and second dampers controlling the amount of cold air introduced to the first and second adiabatic spaces after being generated by the evaporator, respectively;
• and
• a controller controlling the operation of the compressor, the heating unit, and the condenser cooling fan,
• wherein when the second adiabatic space is heated by means of the heating unit, the controller controls the operation of the condenser cooling fan according to ambient temperature of the condenser to maintain the refrigerant that passes through the condenser at a certain temperature level or higher.

A refrigerator comprising:

• a main body including a freezing chamber, a convertible chamber, and a refrigerating chamber;
• first to third cold air adjusting units controlling the amount of cold air supplied to the freezing chamber, the convertible chamber, and the refrigerating chamber;
• a refrigerant compression cycle device installed within the main body and including an evaporator, a compressor, a condenser, and an expander;
• a bypass line bypassing a refrigerant discharged from the condenser;
• and
• a control unit controlling a refrigerant flow path to the bypass line, wherein the convertible chamber is cooled by the cold air and controlled to be heated by the bypass line so as to be maintained within a pre-set temperature range, and a condenser cooling fan cooling the condenser is controlled according to ambient temperature of the condenser in the process of heating the convertible chamber to maintain the refrigerant that passes through the condenser at a certain temperature level or higher.
