In the conventional bottom freezer-type refrigerator configured as described above, the refrigerant, which has been phase-changed into a low-temperature low-pressure gas phase state by the evaporator 8, flows to the compressor 7 and is compressed from low temperature low pressure to high temperature high pressure through the compressor 7, The compressed high-temperature, high-pressure gas phase refrigerant is cooled and condensed in the course of passing through the condenser, and phase-changed into a high-pressure liquid phase. As described above, the refrigerant phase-changed into the high-pressure liquid phase is passed through an expansion valve and subjected to heat exchange in the evaporator (8). After being depressurized (thermally inflated) in a state where it is likely to evaporate, the liquid is flowed to the evaporator 8 in which the evaporation process of the refrigerant is performed. As described above, the refrigerant introduced into the evaporator 8 absorbs heat inside the refrigerator. After the phase change to the low-temperature low-pressure gas phase state to cool the air around it, it forms a refrigeration cycle flowing back into the compressor (7).

At this time, the air (cold air) cooled while losing heat to the refrigerant through heat exchange with the evaporator (8) is discharged from the evaporator (8) side by driving the blower fan (10) installed on the top of the evaporator (8). In this case, the cold air discharged by driving the blower fan 10 is branched to the freezing chamber F and the refrigerating chamber R according to the damper operation.
