ABSTRACT:
An icemaker system provided in a refrigerator is designed to reduce an amount of time required to produce ice. The refrigerator includes a refrigeration system including a number of refrigeration components and a refrigeration loop. The refrigeration loop includes an icemaker section that carries a flow of refrigerant to an ice mold portion of the icemaker system and a bypass section that isolates the icemaker system from the flow of refrigerant. A control system automatically activates the icemaker system regardless of a need for cooling. That is, upon sensing a demand for ice, the control system opens a valve to cause refrigerant to flow through the icemaker section and activates the refrigeration components to speed ice production whether or not additional cooling is required in fresh food and/or freezer compartments.
