An ice piece release system that includes a chilled compartment set at a temperature below 0° C., a warm section at a temperature above 0° C., and a tray in thermal communication with the chilled compartment. The tray includes a plurality of ice piece-forming receptacles and a cavity in thermal communication with the receptacles. The ice piece release system also includes a primary reservoir assembly in thermal communication with the warm section and fluid communication with the cavity of the tray. The ice piece release system further includes a heat-exchanging fluid having a freezing point below that of water, and the fluid resides in the primary reservoir assembly and the cavity of the tray. The primary reservoir assembly is further adapted to move at least a portion of the heat-exchanging fluid in the reservoir assembly into the cavity.

The system according to claim 1, wherein the warm section is an interior portion of an exterior door of the chilled compartment. 5. The system according to claim 1, wherein the warm section is a fresh food compartment. 6. The system according to claim 1, wherein the heat-exchanging fluid is a liquid that comprises water and a food-safe additive to depress the freezing point of the fluid below that of water and the temperature in the chilled compartment. 7. The system according to claim 1, wherein the primary reservoir assembly is further adapted to move heat-exchanging fluid in each chamber into the cavity by the force of gravity. 8. The system according to claim 1, wherein the primary reservoir assembly is further configured to move each chamber to a position above the tray to move heat-exchanging fluid in each chamber into the cavity. 9. The system according to claim 1, wherein the tray further comprises a membrane that separates the cavity from the receptacles. 10. An ice piece release system, comprising: a chilled compartment set at a temperature below 0° C.;a warm section set at a temperature above 0° C.;a tray in thermal communication with the chilled compartment, the tray having a plurality of ice piece-forming receptacles and a cavity in thermal communication with the receptacles;a primary reservoir assembly in thermal communication with the warm section and fluid communication with the cavity of the tray; anda heat-exchanging fluid having a freezing point below that of water,wherein the fluid resides in one or more of the cavity and the primary reservoir assembly, andfurther wherein the primary reservoir assembly is adapted to move heat-exchanging fluid in the reservoir assembly into the cavity by the force of gravity. 11. The system according to claim 10, wherein the primary reservoir assembly further comprises a driving body configured to move heat-exchanging fluid in the primary reservoir assembly into the cavity. 12. The system according to claim 10, wherein the warm section is an interior portion of an exterior door of the chilled compartment. 13. The system according to claim 10, wherein the warm section is a fresh food compartment. 14. The system according to claim 10, wherein the heat-exchanging fluid is a liquid that comprises water and a food-safe additive to depress the freezing point of the fluid below that of water and the temperature in the chilled compartment. 15. The system according to claim 10, wherein the primary reservoir assembly is further configured to move above the tray to move heat-exchanging fluid in the primary reservoir assembly into the cavity. 16. The system according to claim 10, wherein the tray further comprises a membrane that separates the cavity from the receptacles. 17. An ice piece tray assembly, comprising: a plurality of ice piece-forming receptacles;a cavity in thermal communication with the receptacles; anda membrane that separates the cavity from the receptacles,wherein the cavity is configured to receive a heat exchanging fluid to aid in the release of ice pieces that are formed in the receptacles. 18. The tray assembly of claim 17, wherein the cavity is configured with a plurality of ports for controlling a flow of heat-exchanging fluid to aid in the release of ice pieces that are formed in the receptacles. 19. The tray assembly of claim 18, further comprising: a plurality of valves coupled to a controller and the plurality of ports, the controller configured to control the flow of heat-exchanging fluid through the ports by operation of the plurality of valves. 20. The tray assembly of claim 17, further comprising: a mechanical apparatus to aid in the release of ice pieces that are formed in the receptacles.
