A refrigeration system utilizing cooled spillover air from a refrigerated display case 10, the spillover air being recovered and removed from the ambient space through openings 9. The recovered spillover air is conducted through conduit 29 in heat exchange relation to a subcooler 33, lowering the temperature of refrigerant passing to the display case evaporator 19, the still cool spillover air then being used in a space air conditioning system 30.
