/ RTI >
Wherein the cool pack stores the cooling energy by the cool air passing through the auxiliary flow path portion and the stored cooling energy is heated by the defrost heater when defrosting to lower the temperature of the air discharged from the cool air duct, A refrigerator to ensure. 21. The method of claim 20,
And the auxiliary flow path communicates with a cold air discharge port provided adjacent to the cool pack among the plurality of cold air discharge ports. 22. The method of claim 21,
The auxiliary flow path portion includes a communication port communicating with the cool air discharge port, a flow path cover extending forward from the communication port to form an auxiliary flow path through which cool air passes, and a discharge port provided on the entire surface of the flow path cover to discharge cool air The refrigerator. 23. The method of claim 22,
Wherein the air heated by the defrost heater and discharged to the communication port is in direct contact with the cool pack when the refrigerator and the defroster pass through the auxiliary flow path. main body;
A storage compartment provided in the main body so that a front surface thereof is opened;
An evaporator provided behind the storage compartment to generate cool air;
A defrost heater provided under the evaporator;
A refrigerant duct in which the evaporator is installed and a flow path for guiding cool air generated by the evaporator to be supplied to the storage chamber is provided;
An internal high-temperature cool pack disposed adjacent to the flow path and filled with an internal coolant;
/ RTI >
Wherein the internal high-temperature cool pack stores the cooling energy by the cooling air passing through the flow path, and the stored cooling energy is heated by the defrost heater during the defrosting so that the temperature of the air passing through the flow path is lowered into the storage room And a temperature rise inside the storage chamber is delayed. 25. The method of claim 24,
And the cool pack stores the cooling energy by the cool air discharged from the cool air duct, and the stored cooling energy is heated by the defrost heater at the time of defrosting, Wherein the temperature of the air discharged from the cold air duct is lowered to delay the temperature rise inside the storage chamber. 25. The method of claim 24,
