1. A refrigeration appliance (1) comprising:
an outer cabinet (2) comprising a base (2A) suitable to lay on the ground, a roof (2B) and lateral side walls (2C, 2D, 2E) connecting said base (2A) and said roof (2B) in a vertical direction (V);
a first compartment (10), internal to said outer cabinet (2), with an opening (14) for receiving food items and a second compartment (12), internal to said outer cabinet (2), with an opening (16) for receiving food items, said first compartment (10) and said second compartment (12) being separated one to the other;
a refrigeration system (30) comprising an evaporator (38) for cooling down air and a fan (72) configured to force the cooled air to said compartments (10, 12), said fan (72) comprising a rotor (82) with a rotation axis (X) which is inclined with respect to the vertical direction (V);
a first ventilation assembly (50a) apt to channel said cooled air forced by said fan (72) inside said first compartment (10) and a second ventilation assembly (50b) apt to channel said cooled air forced by said fan (72) inside said second compartment (12), said first ventilation assembly (50a) and said fan (72) being associated to said first compartment (10);
further comprising an interconnection duct (110) configured to connect said first ventilation assembly (50a) to said second ventilation assembly (50b), said interconnection duct (110) being arranged downstream of said fan (72) to convey the cooled air forced by said fan (72) towards said second ventilation assembly (50b), wherein said interconnection duct (110) extends along a main axis (Y) which is inclined with respect to said rotation axis (X) of said rotor (82) of an angle (W) comprised between 70° and 110°,
wherein said second ventilation assembly (50b) further comprises one or more inlet openings (102c) configured to withdraw air from said second compartment (12) towards said first compartment (10) and/or back to said evaporator (38),
wherein said second ventilation assembly (50b) further comprises a septum element (105) arranged in correspondence with one or more of said inlet openings (102c) and is configured to at least partially obstruct the air passing therethrough.
