Abstract
A method for controlling a refrigerator having a variable speed compressor and at least two compartments (FR, FZ) cooled to respective temperatures and comprising sensor devices (TR, TZ) for generating control signal responsive to cooling demands of the respective compartments comprises the step of providing the control system with a signal indicative of the total cooling demand on the basis of the sum of each compartment cooling demand, such signal being used to drive the variable speed compressor according to said total cooling demand.

A method for controlling a refrigerator having a control actuator and at least two compartments (FR, FZ) cooled to respective temperatures and comprising sensor devices (TR, TZ) for generating control signals responsive to cooling demands of the respective compartments, the method comprising the steps of:
- generating a signal indicative of the total cooling demand on the basis of the sum of each compartment cooling demand, and using the signal to drive the control actuator according to the total cooling demand.
A refrigerator having at least two compartments (FR, FZ) cooled to respective temperatures, the refrigerator control system comprising sensor devices (TR, TZ) for generating refrigerator control signals responsive to cooling demands of the respective compartments and a control actuator coupled to said control system, wherein the refrigerator control system is adapted to issue a signal indicative of the total cooling demand on the basis of the sum of each compartment cooling demand, such signal being used to drive the control actuator according to such total demand.
The refrigerator having at least two compartments (FR, FZ) cooled to respective temperatures, the refrigerator control system comprising sensor devices (ER, EZ) for generating refrigerator control signals responsive to cooling demands of the respective compartments (FR, FZ) and a control actuator coupled to said control system, wherein the control actuator is a valve (V′) for controlling the flow rate of the refrigerant, the above signals being indicative of temperature difference across each evaporator.
