A cooling system for compartments that keep the relative humidity of products in
refrigeration, characterized because it has a contact duct by means of a heat transfer plate,
applied to the functioning of a two-door and two-compartment refrigerator with independent
temperature regulation between the two compartments, refrigerator and freezer. The
compartments are separated and the air is not mixed, thus the refrigerator compartment
dehydrates less the food contained therein.
