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.

Abstract: An airflow control system in refrigerators and freezers, which comprise: a refrigerating compartment (10; an air cooling compartment (20) lodging an (21) and a fan (22); and an air distributing plenum (23), receiving a forced airflow from the fan (22) and having a front wall (24) provided with air passages (25) through which the forced airflow is supplied to the interior of the refrigerating compartment (10), at least part of the air passages (25) provided in the front wall (25) of the air distributing plenum (23) being operatively associated with respective closing means (40), which are selectively displaced to different operative positions, in which they maintain the air passages (25) with a free area dimensioned as a function of the intensity of the forced airflow to
