Abstract: An evaporator for a refrigeration appliance has a refrigerant line, which extends from an injection point to an outlet of the evaporator. A number of heat exchanger plates are in thermal contact with the refrigerant line and with the surroundings of the evaporator. The refrigerant line has, in an upstream region of the evaporator, at least one constriction, which is spaced apart from the injection point.

Abstract: A refrigeration device has an electrical device part which emits noise during operation. A controller operates the electrical device part in a normal operating power range. A noise sensor detects an intensity of the emitted noise from the electrical device part. The controller is configured to change an operating power of the electrical device part within the normal operating power range and to determine a minimum value of the noise intensity which is detected by the noise sensor and to determine a noise-reduced operating power in order to operate the electrical device part at the noise-reduced operating power.

Abstract: An ice bucket for storing ice pieces having noise dampening characteristics is provided for use in a refrigerator. For example, a noise dampening lining material is disposed on at least a portion of at least one the bottom wall or the side wall in the interior space of the ice bucket. Alternatively, at least a portion of at least one of the bottom wall or the side wall is reinforced with a honeycomb pattern, thereby to reduce vibration transmission and sound amplification. Still further, at least one grommet is disposed on an exterior portion of the bottom wall of the ice bucket so as to rest on a floor of the ice compartment region, thereby to reduce vibration transmission and sound amplification.
