Patent ID: 8806886

Claim:
A refrigerator comprising: a food storage compartment; a first temperature control circuit for directly cooling the food storage compartment, the first temperature control circuit comprising a vapor-compression circuit comprising an expansion device and a first heat exchanger disposed downstream of the expansion device; a second temperature control circuit comprising: a food safe working liquid medium; a second heat exchanger in thermal communication with the first heat exchanger and configured to have the food safe working liquid medium flow therethrough to decrease a temperature of the liquid medium; a first output quick disconnect port provided in a surface of the refrigerator and in flow communication with a supply side of the second heat exchanger; and a first input quick disconnect port provided in the surface of the refrigerator and in flow communication with a return side of the second heat exchanger; and a first temperature controlled device including a liquid circulation circuit comprising a device input port for receiving the liquid medium from the second temperature control circuit and a device output port for returning the liquid medium to the second temperature control circuit wherein the second temperature control circuit is removably connectable to the first temperature controlled device through a functional coupling and decoupling of the first output quick disconnect port and the device input port of the first temperature controlled device and a functional coupling and decoupling of the first input quick disconnect port and the device output port of the first temperature controlled device.
