Abstract: IN PREFERRED FORM, A SIDE-BY-SIDE REFRIGERATOR FREEZER HAVING A VERTICAL PARTITION SEPARATING A FREEZER COMPARTMENT FROM AN ABOVE FREEZING COMPARTMENT WHICH IS DIVIDED INTO A HIGH HUMIDITY SPACE AND A LOW HUMIDITY SPACE. ALL OF THE COMPADRTMENTS ARE COOLED BY AIR FLOW ACROSS A SINGLE EVAPORATOR LOCATED WITHIN A PLENUM IN A FREEZER COMPARTMENT. A PARALLEL FLOW HEAT ECHANGER DIRECTS COLD DRY AIR INTO AN ENVELOPE FOR COOLING THE HIGH HUMIDITY SPACE AND THEREAFTER RECEIVES THE RETURN AIR FROM THE ENVELOPE TO RECOOL IT PRIOR TO PASSAGE INTO THE LOW HUMIDITY COMPARTMENT FOR RETURN FLOW TO THE EVAPORATOR PLENUM. A BY-PASS DUCT FROM THE PARALLEL FLOW EXCHANGER RETURNS PART OF THE RECOOLED AIR TO A LOW POINT IN THE LOW HUMIDITY SPACE TO DIRECT EXCESS AIR FROM THE PARALLEL EXCHANGER BACK INTO THE COOLING PLENUM.
