Abstract
A method for controlling evaporator defrost in a refrigeration appliance having a cooling circuit with a variable cooling capacity compressor is disclosed. The method includes assessing the cooling capacity of the cooling circuit and calculating the defrost time on the basis of such cooling capacity. Defrost time is preferably assessed on the basis of the inverter frequency driving the compressor and/or the percentage of insertion of the compressor.
