The present invention relates to a refrigerator and a working method thereof. The method includes: determining whether to suck air from a storage space (2) capable of keeping a low-pressure state; and if it is determined to suck air from the storage space, activating a vacuum pump (3) to suck at least a part of air out of the storage space (2) through a sucking path (4) connected between the vacuum pump (3) and the storage space (2). According to the advice of the present invention, when the vacuum pump (3) is in a start phase, a branch (5) connected to the sucking path (4) is opened in at least a part of the start phase or an open state of the branch (5) is kept, so as to decrease a start load of the vacuum pump (3). |
