A temperature control system for a refrigerator. The temperature control system is positioned in a refrigerated compartment and fluidly communicates with a cooling fan. The temperature control system includes a vertical partition having a front surface and a rear surface. The rear surface faces a rear wall of the refrigerated compartment and the front surface faces an open end of the refrigerated compartment. An air passage is formed in the vertical partition extending from a lower portion of the vertical partition to an upper portion of the vertical partition. A heater assembly is disposed between the front surface and the rear surface of the vertical partition proximate the air passage wherein air conveyed along the air passage is heated by the heater assembly when the heater assembly is energized.

A method of controlling a refrigerator that includes: operating a cool air supply means with a predetermined output; a controller determining the output of the cool air supply means based on a current temperature of a storage compartment sensed by a temperature sensor while the cool air supply means operates with the predetermined output; and the controller operating the cool air supply means with the determined output. The controller determines that the output of the cool air supply means is decreased or increased when an absolute value of a difference between a previous temperature and a current temperature of the storage compartment is equal to or greater than a first reference value, and wherein the output of the cool air supply means is decreased or increased again when the absolute value of the difference between a current temperature of the storage compartment sensed again after a predetermined time has elapses and the previous temperature of the storage compartment is equal to or greater than the first reference value.

A control method of a refrigerator includes: determining whether a first temperature of a refrigerating compartment satisfies a first temperature condition; based the first temperature satisfying the first temperature condition, determining whether a second temperature of a freezing compartment satisfies a second temperature condition; based on the second temperature satisfying the second temperature condition, determining (i) whether a third temperature of an ice making compartment satisfies a third temperature condition and (ii) whether a driving time for ice making has passed; maintaining operation of a compressor while determining (i) whether the second temperature satisfies the second temperature condition, (ii) whether the third temperature satisfies the third temperature condition, and (iii) whether the driving time has passed; and stopping operation of the compressor based on at least one of (i) a determination that the third temperature satisfies the third temperature condition or (ii) a determination that the driving time has passed.

A refrigerator drawer having a body having a front panel, a rear panel, two side panels, more than one pivotable dividers, each divider pivotable between use and non-use positions, the dividers capable of dividing the drawer body into more than one compartments, a ducted cover and/or a ducted bottom, the ducted cover and ducted bottom each having a channel connecting to more than one fans, and a temperature sensor located within each of the possible compartments is provided.

A method and device for operating a cryogenic tunnel involving the implementation of the following provisions: the measurement of a plurality of key parameters of the method, the division of these parameters into two groups of different parameters, the implementation of one or both of the two following actions on these key parameters: Anticipation actions on the parameters of the 1.sup.st group (in order to act in advance on an anticipated/expected deviation in the deep-freezing quality; and Retroactive actions (countermeasures) on the parameters of the second group, in order to rebalance a measured, effective drift in the quality of the exiting products.

Temperature monitoring device for detecting actual temperatures of contents within a refrigerator or freezer. The temperature monitoring device has a silicone body containing a circuit assembly with a temperature sensor positioned near a thermal break. A bidirectional flange located on top of the device allows it to be suspended from a wire rack. A port located on the body permits the temperature monitoring device to be plugged into a power source and transmit temperature data.

A refrigeration appliance includes a refrigeration circuit with a variable speed compressor, an evaporator, and a variable speed evaporator fan. A controller is operatively connected to the refrigeration circuit and is programmed to calculate a heat load ratio as a ratio between the difference between the ambient temperature and the set point temperature of the fresh-food compartment and the difference between the ambient temperature and the freezer compartment reference point; calculate a speed of one or both of the variable speed compressor and the variable speed evaporator fan as a function of the calculated heat load ratio; and operate one or both of the variable speed compressor and the variable speed evaporator fan at the calculated speed. A method of controlling temperature in cavities of a refrigerator is also provided.
