A built-in refrigerator is disclosed, which includes a cabinet provided in a sink and having a door at a front side thereof and a component chamber at a rear bottom thereof; a molding provided on a floor located at a front bottom of the cabinet; a compressor provided in the component chamber; a cooling fan provided in the component chamber for blowing air to the compressor; a condenser condensing a flowing refrigerant by heat-exchange with the air blown from the cooling fan; and a ventilating passage connecting the component chamber to the outside of the molding for ventilating the component chamber. Also, the built-in refrigerator further includes a dividing strip for dividing the ventilating passage into an inflow passage through which the air is introduced, and an outflow passage through which the air is discharged, wherein the dividing strip is inclined at a predetermined angle θ so as to form an inlet of the inflow passage larger than an outlet of the inflow passage. The condenser may be provided on an inner sidewall of the component chamber.
