Abstract: A system for cooling employee and customer-occupied area of a commercial establishment of a type having an internal refrigerated inventory storage compartment includes a water reservoir located within the refrigerated compartment. Included is an assembly for continually supplying a portion of water from the reservoir to an input of a heat exchanger external of the refrigerated compartment. Further included is an assembly for, after circulation of water through the heat exchanger, return of the water to the water reservoir within the refrigerated compartment. The system also includes an assembly for inputting air external of the refrigerated compartment through the heat exchanger to transfer the air's thermal values to the circulated water. Further provided are a fan and ductwork sub-system for distributing resulting cooled air outputted from the heat exchanger to the employee and customer-occupied areas of the establishment.
