A method of operating a refrigerator appliance includes directing a flow of liquid refrigerant through a sealed system of the refrigerator appliance from a condenser of the sealed system to a fresh food evaporator of the sealed system. the method also includes warming a freezer evaporator of the sealed system while directing the flow of liquid refrigerant through the sealed system to the fresh food evaporator.

The invention relates to a system and method of controlling a plurality of storage volume temperatures in an automated grid-based storage and retrieval system. A plurality of storage volumes is arranged adjacent one another below horizontal rails. A cooler system is provided to draw air from an input, cool the air, and blow the cooled air through an output. For each of the plurality of storage volumes, a first air damper and a second air damper are provided, with the first air damper connected between the output of the cooler system and an air release area above the storage volumes. A controller for each of the plurality of storage volumes adjusts airflow through the first air damper to control an overpressure and air temperature in the air release area, and adjusts airflow through the second air damper to control a pressure differential through the storage volume.

An automated warehouse has a plurality of loading units designed to carry respective articles accommodated in respective storage stations and transferred by a movement device to at least one picking/depositing station, which can be accessed, at least under given operating conditions, in order to retrieve/deposit the articles. At least two loading units are provided with respective refrigerators which communicate with a remote control device to send operating data and/or receive command signals. The loading units transporting the refrigerators are distinct from the latter, are powered to be supplied by an electrical network of the warehouse when they are arranged in corresponding storage stations, and are electrically connected to the respective refrigerators.

The invention concerns an automated storage and retrieval system comprising a first space, a second space, a dividing wall, a storage volume to store storage containers in vertical stacks and a horizontal rail system arranged above where the storage containers would be stored. The invention also concerns a container transfer housing configured to allow transfer of the storage containers between the first space and the second space and a method using such a container transfer housing.
