A cooling system for containers holding chilled foods and beverages within chilled water, is defined by a thermally insulated cooler or other chilling vessel including a quantity of ice, water, food, and/or beverages, and a safely comestible liquid having a lower freezing point than water mixed in the water, the chilling vessel having an input conduit and an output conduit originating in the vicinity of the chilling vessel. In thermal communication with input and output conduits of the chilling vessel is an endothermic element for removal of heat from a defined ambient geometry about the endothermic element, the ambient geometry forming a part of a liquid loop including liquids within the chilling vessel and the endothermic element. Also included is a thermostat in thermoelectric communication between the chilling vessel output conduit and a compressor within the refrigeration circuit, the thermostat for regulating a power input to the compressor to control a temperature of re-circulated liquids to the chilling vessel to a temperature suitable for comestibles stored within liquids in the chilling vessel.
