A refrigerator is provided. The refrigerator includes a main cabinet including a cooling device to generate cold air, a sub-cabinet detachably connected to the main cabinet, a cold air relay duct provided to connect the main cabinet and the sub-cabinet and having a cold air flow path to allow the cold air generated by the cooling device to be delivered to the sub-cabinet, and a heat blocking member provided in a portion of the cold air flow path at which the main cabinet and the cold air relay duct are connected and in a portion of the cold air flow path at which the sub-cabinet and the cold air relay duct are connected.

A refrigeration device includes a storage area which is delimited by a body and a door and which is subdivided by a shelf into an upper and a lower compartment. A drawer is accommodated in the lower compartment. In a stop position of the drawer in which it is pushed into the lower compartment, a front wall of the drawer bears against a front edge of the shelf. A closure element can be moved across a passage or opening in the shelf between a position which blocks the passage and a position which opens the passage over at least part of its cross section.

The present invention relates to a refrigerator, comprising: a dry article chamber, a cold chamber, a first cooling and circulating system and a second cooling and circulating system in which a coolant circulates respectively, wherein an evaporating temperature of the first cooling and circulating system is lower than that of the second cooling and circulating system, the first cooling and circulating system comprises an evaporator arranged inside the cold chamber, and a refrigerating output passage is arranged between the cold chamber and the dry article chamber. By communicating the dry article chamber with the cold chamber of the first cooling and circulating system whose evaporating temperature is relatively low, the absolute humidity of the air entering the dry article chamber is much lower, realizing a lower absolute humidity in the dry article chamber.

A freezing and refrigerating device comprises a box body and a door body. An air supply path supplying cooling air flow to a storage compartment, an air return path enabling the air flow from the storage compartment to pass, a cooling chamber and a defrosting air return path are defined in the box body, wherein the cooling chamber is provided with an air feeding opening part and an air return opening part and contains an evaporator, a blower and a defrosting heater, and the defrosting air return path is communicated with the air feeding opening part and the air return opening part of the cooling chamber. The air supply path and the defrosting air return path are provided with an air supply door and a defrosting air return door respectively. The present invention further provides a defrosting control method of the freezing and refrigerating device.

Methods and systems for an energy efficient MTRS are provided. In one embodiment, a refrigerated transport unit is provided that includes a multi-zone transport unit and an energy efficient MTRS. The multi-zone transport unit includes an internal space separated into a first zone and a second zone. The internal space includes a zone separator separating and thermally isolating the first zone and the second zone. The energy efficient MTRS is configured to control and maintain a separate environmental condition requirement of each of the first zone and the second zone. The energy efficient MTRS includes a remote fan unit provided between the first zone and the second zone. The remote fan unit is configured to provide a heat exchange between the first zone and the second zone for providing climate control within the second zone.

A controller, when a normal cooling operation is being performed, forward-drives a lower-side and an upper-side in-box blower fans, thereby causing internal air cooled by an evaporator to circulate within a commodity storage box in such a way that it enters a rear face duct through a lower-side opening and is discharged from an upper-side opening, and when a cold-maintaining operation is being performed, stops driving the lower-side and the upper-side in-box blower fans, and when a cooling recovery operation is being performed, forward-drives the lower-side in-box blower fan and reverse-drives the upper-side in-box blower fan, thereby causing internal air cooled by the evaporator to enter the rear face duct through the lower-side opening and causing internal air to enter the rear face duct through the upper-side opening, and also causing internal air entered the rear face duct to be discharged from the intermediate opening.

A sectorized cooling arrangement for refrigerators housing products, wherein the arrangement has a direct access to the products without having to open a cooling chamber of the refrigerator, which arrangement has a compartment defining sectorized housings and air passage regulators between the cooling chamber of the refrigerator and the compartment.

A method of controlling a refrigerator including a cold air generator and a cold air transmission unit includes, when a temperature of the storage compartment becomes equal to or greater than a first reference temperature, operating the cold air generator with predetermined cooling power and turning on and operating the cold air transmitter with predetermined output, upon determining that the temperature of the storage compartment becomes equal to or less than a second reference temperature lower than the first reference temperature, turning off the cold air transmitter, and, upon determining that the temperature of the storage compartment becomes equal to or greater than the first reference temperature, turning on the cold air transmitter again, wherein a controller determines operation output of the cold air transmitter based on the cooling power of the cold air generator.

A rotary damper is provided. The rotary damper includes a first housing plate having a substantially flat substrate with a first plurality of windows; a rotary disc having a substantially flat substrate with a second plurality of windows, wherein the rotary disc is in rotatable communication with the first housing plate; and a motor that drives rotation of the rotary disc relative to the first housing plate such that the rotary disc rotates from a first configuration in which the second plurality of windows overlaps with the first plurality of windows of the first housing plate to at least a second configuration in which the second plurality of windows on the rotary disc and the first plurality of windows on the first housing plate do not overlap. Also provided is a refrigeration/freezer unit utilizing the rotary damper to control airflow between a freezer compartment and a refrigeration compartment.

A refrigeration appliance including a partition that defines a through passage between an upper compartment and a lower compartment. A temperature control system is positioned in the upper compartment and includes an air passage. A lower inlet opening extends through a front surface of the vertical partition to the air passage. A damper assembly includes a door that is moveable between a first position and a second position. When the door is in the first position the door fluidly isolates the through passage in the partition from the upper compartment while allowing the lower inlet opening in the vertical partition to fluidly communicate with the air passage in the vertical partition. When the door is in the second position the door fluidly isolates the lower inlet opening from the air passage while allowing the through passage to fluidly communicate with the upper compartment.
