A flap is disposed within the air outlet and is rotatable about an articulation point aligned with respect to the central wall and with a body of the flap extending in an upstream direction within the air outlet. A control element is mounted external to the enclosed area and is operably coupled with the flap to drive rotation thereof.

A medical fluid storage and transportation enclosure can include a housing, a chamber, an exhaust duct, an inlet duct, and a valve. The housing can include walls defining a cavity, where the cavity can be configured to receive a medical product therein. The chamber can be adjacent to the cavity and can be configured to exchange heat with the cavity. The valve can be located in the inlet duct, where the valve can be movable in response to an air.

A ventilation door device for a refrigerator comprises: a frame, having an end plate provided with an opening portion, and having a blocking plate assembly rotatably mounted on the end plate, wherein the blocking plate assembly can rotate between a closed position in which the opening portion is completely closed and an open position in which the opening portion is completely open; a housing, engaging with the frame, wherein a driving chamber is formed between the housing and the frame; and a driving module, wherein the driving module is at least partially held in the driving chamber, and drives the blocking plate assembly to rotate. The frame has a housing engagement portion located on a side edge of the end plate and extending substantially perpendicular to the end plate. The housing is connected to the housing engagement portion of the frame. The blocking plate assembly comprises a blocking plate mounted on the end plate and an elastic component provided on the blocking plate. When the blocking plate assembly is in the closed position, the elastic component abuts the frame and deforms elastically to seal the opening portion. The end plate of the frame has a sealing portion arranged around the opening portion and protruding from the end plate. When the blocking plate assembly is in the closed position, the elastic component abuts the sealing portion of the frame.

A refrigerator appliance includes a cabinet that defines first and second compartments. A fan assembly is configured to direct cooled air from a cooling assembly into the first and second compartments. The fan assembly includes a housing that defines an inlet, a first outlet, and a second outlet. The first outlet is in communication with the first compartment, and the second outlet is in communication with the second compartment. A fan is positioned within the housing and is configured to direct the cooled air from the inlet toward the first and second outlets. A damper assembly is configured to selectively obstruct one of the first outlet and the second outlet.

A refrigerator includes a body including an inner case, a first storage compartment, a second storage compartment, a third storage compartment, a first partition between the second storage and the third storage compartments, a second partition between the first and the second storage compartments, a cold air supplier in the third storage compartment to generate cold air, a first communication hole, a second communication hole to face the first communication hole, a first guide duct formed in the first partition to guide the cold air from the first communication hole to the second communication hole, and a second guide duct formed in the second partition to guide the cold air which has flown to the first guide duct, to the second storage compartment, the second guide duct connected to the first guide duct through the second communication hole.

A positive and negative pressure system and an operation method therefor, and a positive and negative pressure electrical appliance using the positive and negative pressure system. The positive and negative pressure electrical appliance comprises: a positive and negative pressure refrigerator, a positive and negative pressure washing machine, a vacuum dishwasher/fruit and vegetable cleaning machine, a super-oxygenated water washing range hood, a positive and negative pressure oven/fryer/microwave oven, a positive and negative pressure fresh-keeping compartment, a positive and negative pressure fresh-keeping warehouse, and a positive and negative pressure modular cabinet. Regulating airflow with positive and negative pressure, or carrying multiple effective loads such as ozone, an air catalyst, a negative ion, modified atmosphere gas and water for orderly getting in and out of or staying in a positive and negative pressure chamber, and exerting the required effects on objects therein.

A domestic refrigerator has a refrigeration compartment and a container which can be accommodated in the refrigeration compartment and has a lower part for receiving products to be refrigerated and a cover that can cover the lower part. The container has an air inlet opening and an air outlet opening that is at a distance from the air inlet opening. The domestic refrigerator also has a controllable air flow adjustment device and is configured to vary a volume flow rate of an air flow, which enters the container from the refrigeration compartment through the air inlet opening, between at least two values by adjusting an adjustment parameter of the air flow adjustment device. Furthermore, a method ventilates the container which is accommodated in the refrigeration compartment and has the air inlet opening and the air outlet opening.

For effective and energy-saving cooling of articles using straightforward designs, a refrigeration unit, in particular a refrigerated cabinet, freezer cabinet, refrigerated island or refrigerated counter, for storing and/or displaying articles, having a refrigeration chamber for the articles, and having a channel, which is assigned to the refrigeration chamber and is intended for supplying air, wherein two air flows can flow out of an outlet of the channel at different flow speeds and form a double protective air curtain in front of an access to the refrigeration chamber, is configured so that the channel has an element which acts on the supplied air so that the supplied air is divided up into the two air flows with different flow speeds by the element.

A cold insulation container includes: a cold insulation storage including a coolant vessel; a circulating air fan that causes cold air from the coolant vessel to circulate in the cold insulation storage; a thermoelectric generating module attached to an outer surface of the coolant vessel; and a temperature controller that adjusts a temperature in the cold insulation storage. A temperature difference between the coolant vessel and circulating cold air in the cold insulation storage causes the temperature controller and the circulating air fan to be driven by thermoelectric power generated by the thermoelectric generating module.

A refrigerator appliance includes a cabinet with at least one food storage chamber defined in the cabinet. The refrigerator appliance also includes a sealed cooling system in fluid communication with the at least one food storage chamber via a multi-flow system. A plurality of independently cooled zones are defined within the at least one food storage chamber. The refrigerator appliance also includes a temperature control module selectively positionable in one of the plurality of zones. Methods of operating the refrigerator appliance may include and/or a controller of the refrigerator appliance may be configured for locating the temperature control module, receiving a temperature setting from the temperature control module, and adjusting operation of at least one of the sealed cooling system and the multi-flow system in response to the received temperature setting from the temperature control module.
