Abstract:
A cooling system for a refrigerator having a refrigerator compartment with side walls, a ceiling and a floor, a freezer compartment with side walls, a ceiling and a floor, the compartments having independent temperature regulation devices and doors, the freezer compartment having a cooling system including a compressor, a capillary condenser, and an evaporator for cooling air in contact therewith, comprising: a high air mass flow ducting system comprising a duct on each compartment; said duct ride of a temperature conducting material having a metallic heat transfer plate area located between the refrigerator and the freezer compartment, the ducting system functionally operative in different locations between the refrigerator compartment and freezer compartment, allowing passage of air from the refrigerator compartment through the heat transfer plate, the air from the refrigerator compartment not mixing with air circulating through the freezer compartment but cooled by the same heat transfer plate which is also in contact with the air circulating through the freezer compartment and exiting the high air mass flow ducting system at the refrigerator compartment at a temperature of 0.degree. C. or above, to maintain air humidity in the refrigerator compartment; said ducting system separating air passage between the refrigerator compartment and the freezer compartment; anda means for allowing the high air mass flow through the duct in the refrigerator compartment with a small temperature differential.
