ABSTRACT:
A freezer box comprising an enclosure resting on soil, the soil having a tendency to freeze from the cooling effect of the freezer positioned above. Pipes, through which a warm fluid flows, thereby being cooled, buried under the freezer enclosure for warming and preventing the freezing of the sub-freezer soil. A refrigeration system having a condenser for receiving refrigerant vapor and condensing it to a warm liquid. An evaporator for producing cooling by evaporating the liquid refrigerant condensed by a condenser. A pipe for conveying the flow of warm liquid refrigerant from the condenser to the evaporator and a heat exchanger positioned to exchange heat between the flow of cool fluid, having warmed the soil under the freezer, and the flow of warm liquid refrigerant enroute through the pipe from the condenser to the evaporator, thereby warming the flow of fluid and cooling the flow of liquid refrigerant.
