Air flow designs for controlling the temperature in a temperature controlled compartment in a refrigerator are disclosed. One configuration includes a refrigerator with a cabinet having a freezer compartment and refrigerator compartment. The refrigerator may be configured with a first air return pathway between the refrigerator compartment and the freezer compartment for returning relatively warm air from the refrigerator compartment to the freezer compartment and a second air return pathway between the refrigerator compartment and the freezer compartment. A fan may be associated with the first or second air return pathway, that when activated the first or second air return pathway acts as an air supply pathway to supply cold air from the freezer compartment to the refrigerator compartment.

A refrigerated sales cabinet (2) according to exemplary embodiments of the invention comprises a cabinet body (4) having a real wall; a compressor (16) of a vapor compression cycle arranged within a com-pressor compartment (14); and a riser conduit (22) having an inlet port (24) at the compressor compartment (14) and an outlet port (26) positioned outside, particularly behind the cabinet body (4) and above the inlet port (24) such that gas, including leaked refrigerant flows from the compressor compartment (14) through the riser conduit (22) and exits the riser conduit (22) through the outlet port (26).

Systems and methods for prevention of exhaust air re-entrainment in automated storage facility with actively cooled totes are provided. In some embodiments, an actively cooled container includes: an active cooling subsystem; and a heat exhaust outlet to remove heat from the active cooling subsystem; wherein the heat exhaust outlet is angled upward to more effectively remove the heat from the ambient environment of the actively cooled container. In some embodiments, a method of managing a storage area of actively cooled totes includes: determining a plurality of actively cooled totes that require active cooling; and determining an arrangement of the plurality of actively cooled totes in the storage area. The arrangement reduces a column of hot exhaust air formed in the storage area. In this way, the storage of actively cooled totes is made more reliable and more efficient.

Built-in domestic blast chiller expressly designed for domestic use. The hot components (compressor 6, condenser 7) of the blast chiller are positioned on the upper part of its rear wall (24) and in a seat (4) so as to facilitate their ventilation and in order to leave room for an inner space (33) for accomodating baking sheets, trays or grills of the same dimensions as those of traditional domestic built-in ovens.
