Abstract (en)
A method for evaluating frost formation on a usual evaporator (102) in a refrigerator (1), in particular of the forced-air circulation type, comprising a cabinet containing at least one compartment (100), in which the evaporator (102) is located, and at least one fan (3) arranged to generate air circulation within said compartment (100) and cooperating with a usual conveying member (106) for conveying said air from said compartment (100) onto the evaporator (102) so that the air is again cooled. The method comprises evaluating the variation in the flow rate of the air which strikes the evaporator (102), and on the basis of this determining the quantity of frost present on the evaporator (102), then defrosting this latter if necessary. <IMAGE>
