ABSTRACT:
Methods are disclosed for preparing ice, comprising guiding a liquid (22) over an evaporator (11, 12) of a refrigerating circuit (1), heating the evaporator (11, 12) at a determined moment, and collecting ice removed from the evaporator (11, 12). These methods are characterized in that the heating time and the freezing time are governed by the presence and thickness of ice on the evaporator (11, 12), respectively. Also a device for performing these methods is described, comprising a refrigerant condition sensor (28) arranged in the refrigerating circuit (1).
