A refrigerator includes a body including a first storage compartment and a second storage compartment; an evaporator provided in the second storage compartment and configured to supply cold air to the first storage compartment and the second storage compartment; an evaporator cover mounted to the body to cover the evaporator and including at least a first return flow path communicably connected to the first storage compartment; and an insulating partition provided between the first storage compartment and the second storage compartment and including a partition return flow path communicably connecting the first storage compartment and the first return flow path.

A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bay. An air dam selectively permits or prevents airflow through portions of the airflow opening such that airflow may be allowed to flow through the entire opening, only a portion of the opening, or none of the opening.

A refrigerator includes a refrigerator cabinet, a fresh food compartment disposed within the cabinet, a freezer compartment disposed within the cabinet, an ice compartment disposed within the cabinet, and an electronic control system associated with the refrigerator and adapted to monitor and control the fresh food compartment, the freezer compartment and the ice compartment. The control system provides for energy efficient control and operation through various means, including by monitoring state of an ice maker associated with the ice compartment and controlling temperature within compartments of the refrigerator based on the ice maker state. A damper controls air flow between the fresh food and freezer compartments. The control system can direct heat to the damper if the damper becomes frozen.

The storage cell includes ventilation means suitable for creating a rear-to-front air flow or a front-to-rear air flow, an inflatable sealing device, and inflation means which allow the inflatable sealing device to be inflated. The inflatable sealing device includes an upper inflatable sealing element and at least one side inflatable sealing element which directly or indirectly allow, in the inflated state, a seal between the upper wall of the cell and at least one part of the top face of a set of products positioned in the cell and a seal between at least one side wall of the cell and at least one part of one of the side faces of this set of products. The upper inflatable sealing element and the side inflatable sealing element delimit a single inflatable chamber, and the inflation means allow the upper inflatable sealing element and the side inflatable sealing element to be inflated by blowing air into this single inflatable chamber.

A refrigeration appliance including a compartment for storing food items. A partition divides the compartment into a first and a second compartments. The first compartment is disposed horizontally adjacent the second compartment and has a user-selectable target freezer temperature. An evaporator is disposed in the first compartment. An evaporator fan is disposed in the first compartment for conveying cooling air from the evaporator to the first and the second compartments. A temperature control module positioned in the second compartment. The temperature control module includes a body having front and rear surfaces. An air passage is formed in the body and extends between a side inlet opening of the body to at least one outlet opening on the front surface of the body. A heater assembly is disposed between the front and the rear surfaces of the body for heating air in the air passage.

A method for controlling a refrigerator, includes turning off a cold air transmission unit as a temperature of a storage compartment becomes equal to or less than a second reference temperature while a cold air generator is operated, turning on the cold air transmission unit, upon determining that the temperature of the storage compartment is equal to or greater than a first reference temperature which is greater than the second reference temperature, and calculating, by a controller, an operating ratio of the cold air transmission unit based on ON and OFF time of the cold air transmission unit, determining an output of the cold air transmission unit based on the operating ratio of the cold air transmission unit, and operating the cold air transmission unit with the determined output, upon determining that the temperature of the storage compartment is equal to or less than the second reference temperature.

An internal air adjustment device that includes a gas composition adjustment unit including a gas separation film and that adjusts a composition of internal air existing inside a storage box, such as a container, includes a pressure regulating valve that regulates a pressure of air that is supplied from an air pump to the gas separation film of the gas composition adjustment unit.

The invention relates a refrigeration appliance (1) comprising a first compartment (10) and a second compartment (12) for receiving food items, said first compartment (10) and said second compartment (12) being separated one to the other. A refrigeration system (30) comprising an evaporator (38) is provided for cooling down air and a fan (72) forces the cooled air to the compartments (10, 12). The fan (72) comprises a rotor (82) with a rotation axis (X) which is inclined with respect to the vertical direction (V). A first ventilation assembly (50a) is apt to channel the cooled air forced by said fan (72) inside the first compartment (10) and a second ventilation assembly (50b) is apt to channel the cooled air forced by the fan (72) inside the second compartment (12), wherein the first ventilation assembly (50a) and the fan (72) are associated to said first compartment (10). The refrigeration appliance (1) comprises an interconnection duct (110) configured to connect the first ventilation assembly (50a) to the second ventilation assembly (50b), said interconnection duct (110) being arranged downstream of the fan (72) to convey the cooled air forced by the fan (72) towards said second ventilation assembly (50b). The interconnection duct (110) extends along a main axis (Y) which is inclined with respect to the rotation axis (X) of the rotor (82) of an angle (W) comprised between 70° and 110°, preferably an angle (W) comprised between 85° and 100°, more preferably an angle (W) equal to 95°.

A refrigerator appliance includes a cabinet forming a refrigerating compartment defining a plurality of cooling zones, an air circulation duct in fluid communication with the refrigerating compartment, an evaporator provided in the air circulation duct, and a damper assembly in fluid communication with the air circulation duct and the refrigerating compartment. The damper assembly includes a plurality of doors to selectively allow air to enter into selected cooling zones within the refrigerating compartment.

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.
