Abstract: A secondary loop temperature control circuit for a temperature-controlled region in a compartment of a refrigerator is shown. The secondary loop temperature control circuit has a reservoir, configured to have a medium flow there through. A first heat exchanger is in flow communication with the reservoir and is configured to have the medium flow there through. The first heat exchanger is in thermal communication with the temperature-controlled region.

Abstract: A temperature controlled surface in a refrigerator that includes a heat exchanger configured to have the cooling medium flow therethrough to be cooled in thermal communication with a freezer compartment of the refrigerator. A second heat exchanger disposed downstream of the first heat exchanger and configured to have the cooling medium flow therethrough to cool the temperature controlled surface. A pump configured to flow the cooling medium through the first and second heat exchangers. A first heat exchanger is disposed downstream of the storage tank and is configured to have the cooling medium flow therethrough to be cooled. A second heat exchanger is disposed downstream of the first heat exchanger and is configured to have the cooling medium flow therethrough to cool the air and any contents within the temperature controlled compartment.

Abstract: A liquid dispensing apparatus for a refrigerator includes a storage tank in fluid communication with a water inlet. The storage tank is configured to retain water flowing into the water inlet. An auxiliary tank is in fluid communication with the storage tank. The auxiliary tank includes a housing with a piston disposed therein. The piston is movable in a first direction to fill a portion of an interior volume of the housing with water and in a second direction to expel water from the interior volume of the housing.

Abstract: A dispensing system for an appliance has a main tank for holding a fluid. The main tank controls the temperature of the fluid. A dispenser outlet fluidly is connected to the tank by a dispenser fluid line. An auxiliary tank holds a volume of the fluid. A flow control device selectively moves the fluid held in the auxiliary tank to the main tank then through the dispenser fluid line to the dispenser outlet and selectively removes the fluid remaining in the dispenser fluid line after dispensing.

Abstract: In an embodiment of the invention, a refrigerator comprising an ice storage bucket and a cooling system in thermal communication with the ice storage bucket is shown. A first transmitter is configured in the ice storage bucket. A first pulse signal is transmitted from the first transmitter. A first receiver is configured in the ice storage bucket and is further configured to receive the first pulse signal. A first pre-signal response from the first receiver is generated before the first pulse signal. A first pulse signal response from the first receiver generated during the first pulse signal.
