Abstract (en)
A device (10) for reducing energy consumption during the defrosting of a refrigerator (1), such as a domestic refrigerator, comprising at least one compartment, such as a refrigeration compartment (4), either in combination or not in combination with a preservation and/or freezing compartment (3), and provided with at least one electrical resistance heater (8) for automatically defrosting the usual evaporator (7) contained in said compartment (4), said refrigerator (1) being located in an environment such as a kitchen, cellar or the like, comprises at least one temperature sensor (15) connected to a switch member (16) connected in series with said electrical resistance heater (8), said sensor (15) being arranged to measure the temperature of the environment housing the refrigerator (1) and to interrupt electrical feed to the resistance heater (8) when ambient temperature exceeds a predetermined value such as to allow at least partial defrosting of the evaporator (7) without the operation of said resistance heater (8). <IMAGE>
