Abstract
A multi compartment refrigeration appliance is provided wherein each compartment is to be maintained at an independently selected temperature. The appliance includes a temperature selection input device for each compartment, at least one compressor, at least one evaporator, at least one fan for creating an air flow over the evaporator, a temperature sensor located in each compartment, and a control circuit to receive an input from said temperature selection input device for each compartment and a temperature signal for each temperature sensor and to produce an error condition signal with a magnitude dependent on a difference between the selected temperature and the sensed temperature for each compartment. The control circuit also controls a speed of the fan in response to a greater of the error condition signals.
