DEVELOPMENT OF A HIGH EFFICIENCY, AUTOMATIC DEFROSTING REFRIGERATOR-FREEZER.

Author(s) : TOPPING R. F., LEE W. D.

Summary

THE RESULTING 16 CU FT PROTOTYPE USES SIGNIFICANTLY LESS ENERGY THAN THE MOST ENERGY-EFFICIENT AUTOMATIC DEFROST PRODUCT DESIGNS OF COMPARABLE SIZE ON THE MARKET TODAY. A COMPUTER MODEL WAS DEVELOPED TO SIMULATE THE CABINET AND REFRIGERATION UNIT PERFORMANCE, TO EVALUATE ALTERNATIVE DESIGNS AND OPTIMIZE CABINET INSULATION (PLACEMENT OF POLYURETHANE FOAM IN THE CABINET AND THICKER INSULATION IN THE DOORS TO REDUCE THE CLOSED-DOOR HEAT LOAD). MODIFICATIONS TO THE EVAPORATOR SYSTEM PROVIDE FULLY AUTOMATIC FROST-FREE OPERATION WITH A SIGNIFICANTLY REDUCED DEFROST ENERGY REQUIREMENT. HIGHER MOISTURE LEVELS IN THE REFRIGERATOR COMPARTMENT ENHANCE FRESH FOOD STORAGE. A DUAL CONTROL SYSTEM PROVIDES PRECISE TEMPERATURE REGULATION IN THE FREEZER AND REFRIGERATOR COMPARTMENTS.
