Patent attributes
A food prep table may include an upper chilling zone and a lower chilling zone, with each chilling zone containing an evaporation coil system, such as a TurboCoil™ system. The two evaporation coil systems are monitored and controlled by a dual thermostat and control unit (500) having temperature sensor probes in each chilling zone and controlling solenoid valves within each evaporation coil system. By the artful use and implementation of the dual thermostat and control unit, and by the artful use of T junctures in refrigerant supply and return lines, the disclosed embodiments enable a single condensing unit (600) to service both evaporation coil systems to achieve new efficiencies in the cost, refrigeration capacity, and thermal and mechanic attributes of the system. Moreover, an efficient dual air over air flow assembly is disclosed wherein chilled air is moved within the upper chilling zone in a manner that leverages the native configuration and cabinet surface areas of the evaporation coil systems.
