1. An improvement in the forced air flow system for refrigerators, comprising: at least two refrigeration environments ( 1 , 2 ); and a refrigeration air impelling means ( 10 ), having a suction side and a discharge side and forcing the passage of an air flow from a refrigeration environment ( 1 , 2 ) through a respective evaporator portion ( 4 , 5 ), each evaporator portion ( 4 , 5 ) having an outlet side opened to a respective refrigeration environment ( 1 , 2 ), characterized in that the refrigeration air impelling means ( 10 ) comprises only one fan ( 11 ) associated with at least two suction chambers ( 12 ), which are each opened to a respective refrigeration environment ( 1 , 2 ) and to at least two discharge chambers ( 13 ), which are each opened to an inlet side ( 6 ) of a respective evaporator portion ( 4 , 5 ). 2. Improvement, as in claim 1, characterized in that at least one of the suction and discharge chambers ( 12 , 13 ) of the fan ( 11 ) is opened to nozzles of the respective refrigeration ducts ( 20 ) conducting to one of the parts defined by the refrigeration environments ( 1 , 2 ) and the inlet side ( 6 ) of the evaporator portions ( 4 , 5 ). 3. Improvement, as in claim 2, characterized in that each suction chamber ( 12 ) is axially and substantially aligned with a respective discharge chamber ( 13 ). 4. Improvement, as in claim 3, characterized in that the refrigeration ducts ( 20 ) interconnecting the fan ( 11 ) with the inlet side of the evaporator portions ( 4 , 5 ) have respective inlet nozzles ( 21 ) which are vertically aligned to each other and outlet nozzles ( 22 ) which are horizontally and vertically spaced from each other. 5. Improvement, as in claim 4, characterized in that the evaporator portions ( 4 , 5 ) are in the form of vertical ducts defined by at least two vertical fins ( 7 ) which are adjacent to each other and of a single evaporator ( 3 ). 6. Improvement, as in claim 5, characterized in that the evaporator ( 3 ) comprises a vertical plate ( 8 ) parallely provided between the vertical fins ( 7 ) of said evaporator ( 3 ), separating the two portions thereof. 7. Improvement, as in claim 6, characterized in that the vertical plate ( 8 ) is defined by a vertical fin ( 7 ) of the evaporator ( 3 ) having at least one end portion ( 9 ) projecting from a plane containing end edges at the same side of the other vertical fins ( 7 ) of the evaporator ( 3 ). 8. Improvement, as in claim 7, characterized in that it comprises a support structure ( 14 ) carrying the fan ( 11 ) and defining part of the refrigeration ducts ( 20 ) which interconnect the discharge side of the fan ( 11 ) to the inlet side ( 6 ) of the evaporator portions ( 4 , 5 ). 9. Improvement, as in claim 8, characterized in that the support structure ( 14 ) has a plate portion ( 15 ) positioned substantially coplanar with the rotation axis of the fan ( 11 ) and defines a wall portion common to both refrigeration ducts ( 20 ) interconnecting the discharge side of the fan ( 11 ) with the inlet side ( 6 ) of the evaporator portions ( 4 , 5 ). 10. Improvement, as in claim 9, characterized in that the plate portion ( 15 ) defines, for each air flow, a respective deflector ( 16 ), maintaining, in a substantial axial and segregated way, each air flow through the fan ( 11 ). 11. Improvement, as in claim 10, characterized in that each refrigeration duct ( 20 ) connecting the discharge side of the fan ( 11 ) with the inlet side ( 6 ) of the evaporator portions ( 4 , 5 ) contains obturating means for selectively blocking the respective segregated air flow.
