Abstract: A refrigeration control system in combined refrigeration appliances of the type comprising: a refrigerating compartment; a freezing compartment; a compressor; an evaporator; a refrigerating compartment fan and a freezing compartment fan; and a control means to activate and deactivate the compressor and both the refrigerating compartment fan and the freezing compartment fan as a function of the activation and deactivation temperatures detected by the refrigerating compartment temperature sensor and the freezing compartment temperature sensor. The control means is operatively associated with the refrigerating compartment fan to selectively and periodically adjust the speed of the latter, so that the temperature of the refrigerating compartment reaches a deactivation value of the refrigerating compartment fan at the same time in which the temperature of the freezing compartment reaches a deactivation value of both the freezing compartment fan and the compressor.

Abstract: An arrangement for air distribution in a freezer compartment of the type closed by a front door (11) and to which is generally mounted, close to a respective rear wall, an air cooling compartment (30) in which an evaporator (40) and a fan (50) are lodged, said arrangement comprising at least one distributing tube (60) provided in an upper portion of the freezer compartment (10) and having: a rear end (61) maintained in fluid communication with the interior of the air cooling compartment (30); a front end (62) disposed in the front region of the freezer compartment (10) adjacent to the front door (11) thereof and provided with at least one front opening (63) facing said front region of the freezer compartment (10) and the region of the front door (11) of the latter.
