An evaporator is positioned within an evaporator chamber and a diverter assembly is configured for selectively directing cooled air from the evaporator chamber into the freezer chamber. The diverter assembly includes a diverter housing defining a plenum chamber and a damper pivotally mounted within the plenum chamber for selectively directing the cooled air through a first outlet into the first compartment and a second outlet into the second compartment. Diverter assembly may further include a fan for urging cooled air through the plenum chamber.

Abstract: A refrigerator appliance is provided including a freezer chamber divided into a first compartment and a second compartment by a removable mullion. A refrigeration system includes a single evaporator coil having a first evaporator section in series with a second evaporator section. The first evaporator section is positioned in the first freezer compartment to maintain the temperature in that compartment at a fixed, low temperature (e.g., 0° F.). The second evaporator section is positioned in the second freezer compartment which is a “convertible” compartment capable of maintaining temperatures between the freezer and fresh food compartment temperatures (e.g., between about 0° F. and 37° F.).

The refrigerator appliance may include a cabinet defining a chilled chamber, as well as a door attached to the cabinet movable between a closed position and an open position. The drawer assembly may be disposed within the chilled chamber. Moreover, the drawer assembly may include a drawer frame and a forward panel, as described herein.

Abstract: A refrigerator appliance having a defrost chamber is provided herein. The refrigerator appliance may include a cabinet defining a chilled chamber, a defrost drawer housing, and a pair of electromagnetic electrodes. The defrost drawer housing may be mounted within the chilled chamber and define the defrost chamber for the receipt of a food item. The pair of electromagnetic electrodes may be spaced apart along a vertical direction within the drawer housing. Each electromagnetic electrode may include a first heating ring and a second heating ring that is larger than the first heating ring. Each electromagnetic electrode may also include a conductive path and an electrical restrictor element. The conductive path may extend between the first heating ring and the second heating ring. The electrical restrictor element may be coupled to the conductive path and selectively permit a current therethrough.

Abstract: A refrigerator appliance and methods of operation are provided herein. The refrigerator appliance may include a cabinet, a storage bin, a lid, an ozone passage, an air conduit, an air handler, and an ozone filter. The storage bin may include a plurality of walls defining a storage volume. The lid may be positioned on the storage bin to selectively cover the storage volume in a closed position. The ozone passage may be defined through at least one of the plurality of walls in fluid communication with the storage volume. The air conduit may be disposed in selective fluid communication with the ozone passage. The air handler may be disposed in fluid communication with the air conduit to direct ozone through the ozone passage. The ozone filter may be disposed in fluid communication with the air conduit to filter ozone passing from the storage volume through the air conduit.

Abstract: A refrigerator appliance includes a freezer chamber divided into multiple compartments, such as e.g., a first compartment and a second compartment. The refrigerator appliance includes features for conditioning the compartments. In particular, the refrigerator appliance includes features for selectively adjusting the temperature within one of the compartments while maintaining the temperature within the other compartment(s).

Abstract: A duct system for a refrigerator appliance is provided. A fresh food supply duct provides fluid communication between an evaporator chamber and a fresh food chamber. A convertible chamber supply and return duct each provide fluid communication between the evaporator chamber and a convertible chamber. A dual damper is operably coupled to the convertible chamber supply and return duct for selectively and simultaneously opening or closing the convertible chamber supply duct and the convertible chamber return duct.

Abstract: A refrigerator appliance is provided having a fresh food chamber, a convertible chamber, and a freezer chamber. A fan urges a flow of cooled air from an evaporator chamber into a freezer supply duct and a secondary supply duct. A damper housing defines an inlet in fluid communication with the secondary supply duct, a first outlet in fluid communication with the convertible chamber, and a second outlet in fluid communication with the fresh food chamber. A rotary damper is mounted within the damper housing and is selectively rotated to block the flow of cooling air or to supply the flow of cooling air to one or both of the convertible chamber and the fresh food chamber.

Abstract: A refrigerator appliance includes a user interface, an environmental control system, a plurality of compartments disposed within the food storage chamber, each compartment of the plurality of compartments defining a food storage sub-chamber, at least one of the food storage sub-chambers having independently controlled environmental conditions, the independently controlled environmental conditions of the at least one food storage sub-chamber comprising temperature and humidity, at least one sensor associated with each food storage sub-chamber having independently controlled environmental conditions, and a controller in operative communication with the user interface, the environmental control system, and the at least one sensor, the controller operable to identify a food item, determine preferred environmental conditions for storage of the identified food item, and provide an indication of which of the food storage sub-chambers most closely matches the determined preferred storage conditions.

Abstract: The present subject matter relates energy management systems and methodologies wherein control over local appliances is implemented to control stress on a local transformer to which a plurality of user locations may be connected. Some of the user locations are provided with home energy management (HEM) devices that control operation of certain appliance at their location based in part on constraints associated with the local transformer. The HEMs may negotiate among themselves how to meet the constraints of the local transformer and, in certain circumstances, take into consideration estimates of usage at user locations connected to the local transformer but that do not have their own HEM.

Abstract: An energy management system includes a module for an energy consuming device. The module has a module main controller including a computer processor in communication with a module computer readable storage medium containing computer executable code. When the computer executable code is executed by the computer processor, it performs a method including determining whether a demand state is a peak demand state, employing a reduced operational mode of the energy consuming device during a peak demand state, and employing a normal operational mode of the energy consuming device during a demand state other than a peak demand state. In an embodiment, the system also includes a system main controller in communication with the module.
