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 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 is proposed. The refrigerator includes a refrigerating compartment, a freezing compartment, and an ice-making compartment. The refrigerating compartment is configured to receive cool air from a refrigerating compartment side grill fan assembly, and the ice-making compartment is configured to be located any one refrigerating compartment door and to receive cool air from a freezing compartment side grill fan assembly with the freezing compartment. The refrigerating compartment side grill fan assembly is configured to supply a greater amount of cool air to the side where the ice-making compartment and the refrigerating compartment side grill fan assembly are located, and to perform cool air supply proportional to temperature influence provided from the ice-making compartment and the refrigerating compartment side grill fan assembly.

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 blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

In one instance, a cooling unit for cooling a refrigerated room includes a fan base and a fan guard that both twist and rotate to change pitch thereby allowing the cooling unit air to be directed in many directions as desired. The fan base has a flange portion and a conduit portion. The conduit portion of the fan base mates with an opening in a conduit member of the fan guard. The opening in the fan guard is sized and configured to form an interference fit with at least a portion of a conduit portion of the fan base while allowing rotation of the fan guard relative to the fan base about the longitudinal axis. The second longitudinal end of the fan-guard conduit member is at least partially angled to allow the rotation about a lateral axis in order to pitch the direction of the grill front wall.

The efficiency of a device for cooling or heating objects on a belt that moves through a path of a helix, in which gaseous cooling or heating medium is circulated within the device, is improved by positioning fans that circulate the cooling or heating medium so that the fans are distanced from the top of the helix.

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 refrigerator includes an evaporator, a first fan, a first duct, a second fan, a second duct, and a plate. The first duct is mounted between the evaporator and the first fan. The first fan moves air from the first duct into a first zone. The second fan moves air from the second duct into a second zone. The plate is mounted between the evaporator and the second duct. The plate includes a plate aperture wall that defines a duct aperture formed through the plate. A first aperture of the second duct is adjacent the second fan. A second aperture of the second duct is positioned to encompass the duct aperture. A center of the duct aperture is positioned a distance from a center of the evaporator measured in a first direction. The distance is between 0% and 40% of a total length of the evaporator in the first direction.

A controller within a refrigeration application controls temperature and humidity within a compartment of the refrigeration application. The controller may begin cooling the compartment based on a measured temperature value for the compartment. The controller may delay a starting time of an evaporator fan within the compartment based at least in part on a measured humidity value for the compartment. The controller may also adjust an operating time of a condenser fan based at least in part on the measured humidity value.
