Abstract: An ice maker assembly is disposed in the ice compartment of a refrigerator, the ice maker assembly including an ice maker tray/evaporator having an evaporator cooling tube which is in direct contact with an ice maker tray portion, and a tray temperature sensor for sensing a temperature of the ice maker tray portion. A controller is configured to control ice making, ice harvesting, and ice maintenance based on the temperature sensed by the tray temperature sensor.

Alternatively, an additional temperature sensor can be disposed inside an ice maker assembly gear box for sensing a temperature of a housing of the gear box. In that case, the tray temperature sensor and the additional temperature sensor are the only temperature sensors used to control ice making, ice harvesting, and ice maintenance.

Abstract: A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.
