A refrigerator appliance may include a cabinet, a liner, a thermodynamic assembly, an air conduit, a heat exchange (HE) sleeve, a conductive ice mold, and a water dispenser. The liner may define an icebox (IB) compartment. The air conduit may be disposed within the IB compartment to define a conduit path between a conduit inlet and a conduit outlet downstream from the conduit inlet. The heat exchange (HE) sleeve may be disposed along the air conduit between the conduit inlet and the conduit outlet. The HE sleeve may include a conductive panel extending across the conduit path. The conductive ice mold may be mounted to the HE sleeve within the IB compartment. The conductive ice mold may define a mold cavity outside of the air conduit. The water dispenser may be positioned below the conductive ice mold to direct an ice-building spray of water to the mold cavity.

An icemaker for making clear ice shapes using a process that removes and replenishes a freezable liquid, such as water, from and to one or more ice-mold cavities during freezing of the freezable liquid in the ice-mold cavity(ies). This process removes air bubbles from the freezable liquid during freezing that would otherwise result in cloudy ice. In some embodiments, the icemaker includes a suction system to draw freezable liquid from the cavity(ies) and a replenishment system to replenish the cavity(ies) with freezable liquid to replace the freezable liquid that the suction system draws out of the cavity(ies). In some embodiments, the replenishment includes a reservoir containing freezable liquid and the suction system includes a pump that draws the freezable liquid from the cavity(ies) and discharges it to the reservoir. Methods of making clear ice and other systems for making clear ice are also disclosed.
