ABSTRACT:
A counter current defroster-humidifier arrangement, having a plurality of layered sets of parallel air flow passages formed by corrugated paper-like or porous material, is located in the above-freezing compartment of a refrigerator. The device receives moisture-laden air from the above-freezing compartment for flow in one direction through first alternate sets of parallel layered sets of air passages. The moisture is both absorbed and adsorbed within the passages and transpires or diffuses through the passage walls into the second alternate layered sets of passages which receive cooled dry air exiting the evaporator chamber for flow in the opposite direction. Thus, the arrangement substantially reduces the moisture content of the food compartment air prior to its return to the evaporator chamber while maintaining the food compartment in a high humidity food preserving condition by returning the transpired absorbed and adsorbed moisture to the chilled return air.
