Abstract
A refrigerator includes an ice making device for producing ice cubes. The ice making device includes a mold body having a plurality of ice forming cavities adapted to hold fluid. In an ice making cycle, air is evacuated from the cavities by a vacuum system, thereby depressurizing the cavities. Then, liquid is delivered to the depressurized cavities by a liquid delivery system, whereby an initial portion of the liquid bubbles up within the respective cavities. Once ice cubes have been formed within the cavities, the cavities are heated by a heat transfer system, thereby partially melting the ice cubes and aiding in the expulsion of ice cubes from the cavities.
