Abstract
A refrigerator with a condenser and a fan for the forced ventilation of the condenser, the refrigerator including a fan control circuit for controlling the fan to provide variable throughflow of air from the fan and an assembly for measuring temperature in operative communication with the fan control circuit for operating the fan in a temperature-dependent manner.
Claims6
A refrigerator with a condenser, a compressor and a fan for the forced ventilation of the condenser, the refrigerator comprising:
- a fan control circuit for controlling the fan, the control circuit being configured to selectively delay fan operation and to terminate fan operation based on compressor operation and to provide variable throughflow of air from the fan by controlling fan speed;
- and
- an assembly for measuring ambient refrigerator temperature in operative communication with the fan control circuit for operation of the fan by the fan control circuit based on the ambient temperature of the refrigerator wherein fan speed varies directly with ambient temperature of the refrigerator,
- wherein the refrigerator includes a door and the control circuit is configured to evaluate when the door is opened and to control fan speed based on the door being opened between successive compressor operations.
