Disclosed is a refrigerator including a temperature controlled room with improved utilization of space because no component for cooling or heating is positioned inside a temperature controlled room. The refrigerator includes a cabinet; a storage room provided inside the cabinet; a temperature controlled room positioned inside the storage room and being at inside temperature which is independent from inside temperature of the storage room; a cool air flow path guiding cool air generated inside the cabinet to inside of the storage room; a first fan positioned on the cool air flow path to supply the cool air to the storage room; a cool air supplier forming at least one portion of the cool air flow path and including a second fan to supply the cool air to the temperature controlled room; and a heating portion configured to heat air to supply hot air to inside of the temperature controlled room.

The invention relates to an electrically conductive film (10) having an electrically nonconductive substrate layer (12), and an electrically conductive metal layer (14) that has a structure produced by material removal and that on a first side is joined, at least in sections, to the substrate layer (12).

A refrigerator appliance includes a chilled chamber defining a plurality of cooling zones and a lighting assembly comprising a plurality of lighting zones corresponding to the plurality of cooling zones. A climate control system generates and selectively directs a flow of cooling air into the plurality of cooling zones such that the temperature in each zone is independently regulated and the lighting assembly selectively illuminates the plurality of lighting zones to provide user feedback regarding the operation of the climate control system, e.g., by indicating which zones are receiving the flow of cooling air, by notifying a user when a zone has reached a setpoint temperature, or by identifying the presence and location of a flow restriction.
