Refrigerators keep food cold by pumping thermal heat outward

Compressor coils absorb interior cabinet heat and radiate energy into the room

A domestic refrigerator does not generate coldness; it actively extracts thermal energy from inside the insulated cabinet and exhausts it into the surrounding room. A compressor circulates chemical refrigerant through evaporator coils, evaporating liquid into gas to absorb internal heat before condensing it back into liquid outside.
