Segregated air supply for an accurately temperature controlled compartment
In a refrigerator having a cabinet with insulated walls defining a first compartment and a second compartment, and an evaporator in the first compartment to cool the first compartment; means to cool the second compartment is described comprising: means for defining an opening in an insulated wall of the first compartment adjacent the evaporator; a heat transfer plate completely covering the opening, the plate having a first surface exposed to the first compartment and a second surface; a duct having a first terminal end and a second terminal end, each opening to the second compartment; the second plate surface forming a portion of the duct; means for circulating air from the second compartment through the duct in heat exchange contact with the second plate surface; means associated with the second plate surface for capturing condensate developed on the plate second surface during defrosting of the second plate and for directing the condensate to the first compartment; whereby, the condensate will not enter the second compartment but will rather be disposed of along with condensate from the evaporator.
