A refrigerator appliance includes a cabinet defining a food storage chamber. A method of operating the refrigerator appliance includes operating a fan of the refrigerator appliance at a first level during a normal mode. The first level is determined by a call for cooling based on a set temperature for the food storage chamber. The method also includes operating the fan at a second level greater than the first level during an enhanced odor control mode.

A refrigerator supplies cool air generated by a cooler to a plurality of storage compartments by cooling fan (27). Cooling fan (27) is formed of multi-blade fan (27a) which blows cool air in a circumferential direction. Guide case (33) of cooling fan (27) has discharge opening portion (35) which supplies cool air to the plurality of storage compartments at one portion.

A refrigerator, comprising: a refrigerator body, an air duct assembly and a branched air supply apparatus; the air duct assembly has an accommodating cavity, air passages, and air supply ports opening forward; the air passages comprise a first air passage and a plurality of second air passages; the branched air supply apparatus is installed in the accommodating cavity and has a peripheral wall portion; the peripheral wall portion defines a plurality of air outlets, the plurality of air outlets comprising a first air outlet and a plurality of second air outlets; the first air passage is communicated with the first air outlet and a first storage space; each second air passage is communicated with one second air outlet and one or more air supply ports, and each of the second air outlets communicates with at least one second air passage.

A refrigerator comprising a refrigerator body provided with a refrigerating compartment, an ice maker, an ice-making air duct, a first fan assembly disposed in the ice-making air duct and an ice maker evaporator is disclosed. The ice-making air duct comprises an air inlet duct and an air return duct, which are both disposed in a foaming layer of the refrigerating compartment, and one ends thereof close to the ice maker extend into a foaming layer on a door body of the ice maker. The first fan assembly is detachably disposed in the air return duct, and may be integrally disassembled from and installed in the air return duct. The ice maker evaporator is disposed between the air inlet duct and the air return duct and at the side far away from the ice maker.

A refrigerator includes: a cabinet including a freezing chamber; an evaporator located at one side of the freezing chamber; a freezing chamber fan configured to supply cool air to the freezing chamber; an ice maker located in the freezing chamber and configured to perform ice-making; an ice bin located below the ice maker and separates and stores ice made in the ice maker; an ice detection device which detects whether or not the ice stored in the ice bin is full; and a control unit configured to control the freezing chamber fan according to a detection signal of the ice detection device. The control unit is configured to turn off the freezing chamber fan when ice-fullness is detected by the ice detection device and turn on the freezing chamber fan when the ice-fullness is not detected by the ice detection device.

According to one embodiment, a method, computer system, and computer program product for item temperature maintenance is provided. The embodiment may include capturing weather information related to current and predicted weather conditions. The embodiment may also include identifying a period of time when the captured weather information indicates an outdoor temperature satisfies a temperature threshold. The embodiment may further include calculating a thermal advantage of utilizing outdoor air to supplement a normal process of a thermodynamic device. The embodiment may also include, in response to the thermal advantage satisfying a threshold, performing supplementation of the normal process of the thermodynamic device.

A refrigerator includes a main body, a damper, a compressor, a condenser, a switchable chamber evaporator, a freezing chamber evaporator, a switchable chamber capillary tube, a bypass capillary tube, a path switching device, a switchable chamber fan, a freezing chamber fan, and a controller. The controller rotates the switchable chamber fan and the freezing chamber fan at different speeds according to satisfaction of a temperature of the switchable chamber, dissatisfaction of the temperature of the switchable chamber, satisfaction of a temperature of the freezing chamber, dissatisfaction of the temperature of the freezing chamber, satisfaction of a temperature of the refrigerating chamber and dissatisfaction of the temperature of the refrigerating chamber.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

A refrigerator (100) having an air blower (102) located downstream of a transverse side of an evaporator (150) is provided. The refrigerator includes: a cabinet defining a cooling chamber (133) and at least one storage compartment, the evaporator (150) arranged in the cooling chamber (133), and the air blower (102) arranged on the transverse side of the evaporator (150) and located downstream of the evaporator (150) in an airflow path. The air blower (102) does not occupy a space behind or in front of the evaporator (150), which reduces a space occupied by the cooling chamber (133) in a front-rear direction, and ensures the thickness of a foamed material between the rear of the cooling chamber (133) and a housing of the cabinet.

The present disclosure provides a refrigerator operation control method capable of accurately recognizing whether an abnormal situation occurs as well as determining a defrosting time using an identified rotation speed of a blowing fan.
