A rotating shelf assembly includes a shelf and a rotating disk rotatably mounted to the shelf and driven by a drive mechanism, such as an electric motor and gear assembly. A controller is configured for operating the drive mechanism to rotate the rotating disk to a desired angular position in response to an external stimulus or position parameter, such as a user, outside weather data, food quality, time/date, etc.

A filter assembly with features for improved filter cartridge placement and detection are provided. The filter assembly includes a filter cartridge and a filter housing for receiving the filter cartridge. A contact member extends from the filter housing for engaging the filter cartridge when the filter cartridge in the installed position. A first contact is mounted to the contact member and a second contact is mounted to the filter cartridge such that the first contact and the second contact establish an electrical connection when the filter cartridge in the installed position.

A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.

An insulated structure comprises a first panel and a second panel coupled to the first panel. The first and second panels define an insulating cavity therebetween. A port is defined by the second panel. The port is an opening into the insulating cavity. A connector is coupled to the second panel. A tube is coupled to the connector and extends parallel along the second panel.

A refrigerator includes a storage chamber having an opening; a drawer type door to open or close the opening; a display positioned at the drawer type door; a first connector provided at a sidewall of the storage chamber; a second connector provided at the drawer type door and being electrically connected to the display; a first frame coupled to an inner wall of the storage chamber, the first frame to cover the first connector; a second frame coupled to the drawer type door, the second frame to support a storage box; and a wire electrically connected between the first connector and the second connector. The first frame has a first accommodating part to accommodate one portion of the wire and the second frame has a second accommodating part to accommodate another portion of the wire.

An air-conditioning apparatus includes a heat exchanger, a fan, and a controller. The heat exchanger causes heat exchange to be performed between a medium that transfers heat, and air. The fan sends air to the heat exchanger. The controller determines whether clogging due to foreign matter has occurred in the heat exchanger, based on a command voltage varying in accordance with the rotation speed of a fan motor that drives the fan.

Operating a vapor compression system including determining a total heat delivered by the vapor compression system, determining a total electrical energy consumed by the vapor compression system while delivering heat, maintaining a total electrical energy consumed by the vapor compression system during a defrosting cycle, determining a cumulative coefficient of performance of the vapor compression system based on the total heat delivered, the total electrical energy consumed by the vapor compression system while delivering heat, and the total electrical energy consumed by the vapor compression system during the defrosting cycle, and initiating a defrosting cycle based the cumulative coefficient of performance.

The present invention provides a transport container comprising; a first container having a first inner wall with a storage space for storing a transported object and a first outer wall provided on the outside of the first inner wall so as to form, with the first inner wall, a vacuum space therebetween; a first lid that is heat-insulating and is for removably sealing a first opening of the first container; a second container having a second inner wall with a space for storing the first container and the first lid and a second outer wall provided on the outside of the second inner wall so as to form, with the second inner wall, a vacuum space therebetween; a second lid that is heat-insulating and is for removably sealing a second opening of the second container; and a heat storage material for surrounding the transported object inside the storage space.

A refrigeration appliance includes a freezer compartment. An ice maker return duct fluidly couples an ice maker compartment and the freezer compartment. A pressure sensor is positioned within the freezer compartment and is configured to detect a pressure differential between the freezer compartment and an external environment. A fan is positioned within the ice maker return duct and is configured to be activated when the pressure within the freezer compartment is lower than the external environment.

A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.
