Method of operating a lighting assembly in a refrigerator appliance

A refrigerator appliance includes a chilled chamber defining a plurality of cooling zones and a lighting assembly comprising a plurality of lighting zones corresponding to the plurality of cooling zones. A climate control system generates and selectively directs a flow of cooling air into the plurality of cooling zones such that the temperature in each zone is independently regulated and the lighting assembly selectively illuminates the plurality of lighting zones to provide user feedback regarding the operation of the climate control system, e.g., by indicating which zones are receiving the flow of cooling air, by notifying a user when a zone has reached a setpoint temperature, or by identifying the presence and location of a flow restriction.

Temperature probe for a refrigerator appliance

A refrigerator appliance assembly includes a cabinet having at least one chamber for receipt of an item, a door permitting access to the at least one chamber, a temperature port within the at least one chamber, and a temperature probe communicatively coupled with the temperature port. The temperature probe is configured to generate one or more first temperature signals representative of an actual temperature of at least one of the item or the at least one chamber. The refrigerator appliance also includes a controller communicatively coupled to the temperature probe. Thus, upon receipt of the one or more first temperature signals, the controller determines the actual temperature of at least one of the item or the at least one chamber. Further, the refrigerator appliance also includes a user interface communicatively coupled to the controller. Accordingly, the user interface displays the actual temperature to a user and allows the user to adjust the actual temperature of at least one of the item or the at least one chamber to a desired temperature of the item.

Temperature control system

A temperature control system is used for controlling a temperature of a control target to a target temperature that changes with lapse of time. The system includes: a first adjustment apparatus that includes a first tank that stores a first heat transfer medium, adjusts the temperature of the first heat transfer medium to a first set temperature, and supplies the temperature-adjusted first heat transfer medium; a first circulation circuit through which the first heat transfer medium flows from the first adjustment apparatus to a first flow-through path and returns to the first adjustment apparatus; an adjustment section that adjusts an amount of heat supplied from the first flow-through path to the control target; a memory that stores a relation between the lapse of time and the target temperature; and a controller.
