A distributed refrigeration appliance system for use in a residential kitchen and other locations in a dwelling and includes multiple separate refrigeration appliance modules, a central cooling system and a cooling circuit. The system can also include one or more satellite stations having a heat exchanger and arranged for supplying chilled air to one or more refrigeration appliance modules. One or more refrigeration appliance modules can include a thermal cascade cooling device to cool the module to lower temperatures than the cooling circuit can attain. One or more refrigeration appliance modules can be refrigeration/storage modules that can provide refrigerated, unconditioned or heated storage space. The central cooling system can be a vapor compression system having a refrigerant circuit connecting the modules. Alternately, the central cooling system can cool a secondary cooling medium circuit. The refrigeration system can also have more than one refrigeration machine providing cooling to the secondary refrigeration loop.
