Abstract

A refrigerator includes a first compartment, a second compartment, a compressor compressing and discharging refrigerant, a first evaporator connected to the compressor to cool the first compartment, the first evaporator having an outlet, a second evaporator connected to the compressor in parallel with the first evaporator to cool the second compartment, the second evaporator having an outlet, a check valve connected between the outlets of the first and second evaporators to prevent the refrigerant out of the first evaporator from entering the second evaporator, a flow-path switching element for switching a cooling mode between a first cooling mode in which the refrigerant discharged from the compressor is caused to flow through the first evaporator to thereby cool the first compartment and a second cooling mode in which the refrigerant discharged from the compressor is caused to flow through the second evaporator to thereby cool the second compartment, and a control device provided for controlling the compressor and the switching element so that the first and second cooling modes are switched alternately and so that the compressor is stopped under the first cooling mode with drop o…
