A refrigeration appliance includes a refrigeration circuit with a variable speed compressor, an evaporator, and a variable speed evaporator fan. A controller is operatively connected to the refrigeration circuit and is programmed to calculate a heat load ratio as a ratio between the difference between the ambient temperature and the set point temperature of the fresh-food compartment and the difference between the ambient temperature and the freezer compartment reference point; calculate a speed of one or both of the variable speed compressor and the variable speed evaporator fan as a function of the calculated heat load ratio; and operate one or both of the variable speed compressor and the variable speed evaporator fan at the calculated speed. A method of controlling temperature in cavities of a refrigerator is also provided.
