Refrigerator and control method for the same

The invention improves the efficiency and converts the refrigerant flow path circulating in the refrigeration cycle and the cooling operation to the defrosting operation and the refrigerating compartment for the freezing chamber evaporator and can at the same time, by making the refrigerant to defrost the freezer compartment evaporator, reducing the power consumption of the refrigerating cycle It relates to a refrigerator capable. The present invention is a refrigerant flow path that performs a cooling operation for cooling the freezing compartment evaporator, a defrosting operation and the refrigerating chamber for the freezing chamber evaporator for cooling the freezer compartment is connected to the evaporator, in parallel with the evaporator for cooling the refrigerating compartment at the same time It provides a refrigerator including a converter. Coolant flow channel converter, a first bypass pipe, a second bypass pipe, a first refrigerant flow control valve
