Abstract: The present invention provides a control method of a refrigerator, comprising: a first defrosting step of defrosting an evaporator and terminating the defrosting when the evaporator reaches a first temperature; a step of detecting pressure difference by means of a differential pressure sensor for measuring pressure difference between a first thru-hole, disposed between the evaporator and an inlet through which air flows in from a storage compartment, and a second thru-hole disposed between the evaporator and an outlet through which the air is discharged into the storage compartment; and a second defrosting step of additionally defrosting the evaporator if the measured pressure difference is greater than a configured pressure.

Abstract: A refrigerator having an air pressure controllable storage container is allowed to control air pressure of the storage container to be temporarily lower than initial air pressure by turning on and off a vacuum pump. The vacuum pump sucks internal air of the storage container, and a controller turns on the vacuum pump such that internal air pressure of the storage container is lower than the initial air pressure, and turns off the vacuum pump such that the internal air pressure is restored to the initial air pressure.
