Provided is a refrigerator including a main body, a first storage chamber and a second storage chamber provided inside the main body with front sides thereof open, an evaporator, while being arranged inside the main body, configured to generate cold air and arranged behind the first storage chamber, a first duct configured to supply the cold air generated from the evaporator to the first storage chamber, a second duct configured to supply cold air to the second storage chamber, and a connection duct configured to connect the first duct and the second duct to cause the cold air inside the first duct to flow into the second duct, and a damper configured to selectively open and close the connection duct, wherein the damper is provided inside the first duct, and the second duct has a front surface in a form of a flat surface.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

A refrigeration appliance includes a freezer compartment for storing food items. An ice maker is disposed within the freezer compartment and includes a removable ice bin having an internal cavity. A front cover closes a front open end of the ice bin. The front cover includes a front face oriented toward a front of the freezer compartment, a rear face, and a recess formed in the rear face. The rear face of the front cover is disposed adjacent to a horizontal edge portion of the ice maker when the removable ice bin is disposed within the ice maker wherein the recess defines a gap between the front cover and the horizontal edge portion that fluidly communicates with the internal cavity of the removable ice bin. A plurality of ribs is disposed within the gap for directing air exiting the internal cavity of the removable ice bin into a predetermined direction.

In an air conditioner for a vehicle, a flow speed of air flowing through a first ventilation part of an evaporator is faster than a flow speed of air flowing through a second ventilation part of the evaporator when an intensive air-conditioning operation for a driver seat is operated, with respect to a case where a normal air-conditioning operation is performed. In this case, a correct target evaporator temperature is calculated to be higher by a predetermined temperature than a target evaporator temperature, and a detected temperature detected by an evaporator sensor is approached to the correct target evaporator temperature. Therefore, it can restrict the second ventilation part from being frosted.

A device having multiple air flow paths for a refrigerator, comprising: a housing provided with at least one air inlet and a plurality of air outlets; an adjustment member having a rotation disk member and rotatably provided in the housing about an axis of the rotation disk member to completely shield, partially shield or completely expose each air outlet when being at different rotation positions, so as to regulate respective air discharging areas of the plurality of air outlets; a motor provided at a radially outer side of the rotation disk member; and a transmission mechanism configured to transfer a rotation motion outputted by the motor to the adjustment member at a reduced speed.

An air duct assembly is provided that is configured to supply air to a compartment and including: an outer cover housing, configured to be fixed to an outer side of a compartment wall defining the compartment, an external accommodating cavity being defined inside the outer cover housing; an inner cover housing, configured to be disposed opposite to the outer cover housing on an inner side of the compartment wall, an internal accommodating cavity being defined inside the inner cover housing. An air inlet is formed in the outer cover housing, so as to allow external air to enter the external accommodating cavity via the air inlet. A vent is formed in the compartment wall, so that the external accommodating cavity communicates with the internal accommodating cavity. An air outlet is formed in the inner cover housing, so as to supply the air in the internal accommodating cavity to the inside of the compartment.

An apparatus provides pulsed impingement jets to a sub-chamber within an impingement hood of a freezer, and includes a blower having an inlet and an outlet at an interior of the freezer; a duct having a first end in fluid communication with the outlet and a second end opening into the sub-chamber; and a flow valve disposed in the duct proximate the second end opening, the flow valve movable in repetitive open and closed positions for providing repetitive, discrete pulses of the impingement jets from the second end opening of the duct into the sub-chamber.

A refrigeration system includes at least one compressor, a condenser, one or more sensors, and a controller. The one or more sensors are operable to sense data associated with the refrigeration system. The controller is operable to receive operating data associated a first control variable and a second control variable, the operating data received from the one or more sensors. The controller is further operable to determine, based on the operating data, that a control objective is not met, and operate the refrigeration system according to a configuration selected to cause the control objective to be met in response to determining that the control objective is not being met, wherein operating the refrigeration system according to the configuration selected to cause the control objective to be met comprises overriding control of the second control variable until the control objective is met.

A refrigerator is disclosed, where the flow of the cold air is selectively controlled to keep the internal temperature and humidity of a produce box relatively constant. The relatively constant internal temperature and humidity of the produce box is advantageous for optimally maintaining the freshness of produce stored within the produce box. The refrigerator includes a refrigerator main body forming an outer shell of the refrigerator, a cold air generation unit configured to generate a cold air required within the refrigerator main body, a produce storage unit configured to accommodate a produce box, a cold air circulation module configured to supply the cold air to the produce box, and a closing mechanism configured to selectively discharge the cold air existing within the produce box.

A damper device may include a baffle to open/close an opening part; a motor; and a gear train connecting the motor and the baffle and including a partially toothless gear and a sector gear. The partially toothless gear may include an outer peripheral part so as to have an outer peripheral face curved along a tooth tip circle of the teeth part. The outer peripheral part may include an end face at a midway position of the teeth part in the axial line direction where a length in the axial line direction is shorter than a tooth width of the teeth part. The sector gear may include a first tooth cut out facing the outer peripheral face and configured to enter in to an inner peripheral side of the tooth tip circle. A second tooth disposed adjacent to the first tooth and configured to abut the outer peripheral face.
