A refrigerator fan device, comprising: a fan motor (10) which has a fan rotor (12) and which can be provided in an air duct between an air inlet (16), a refrigerator heat exchanger (15), and/or a refrigerator compressor (14) and an air outlet (18) on or in a refrigerator housing (20, 22), said fan motor (10) being connectable to a unit of the refrigerator, via electrical supply and/or control lines, wherein the fan motor (10) is realized as a brushless speed-controllable DC motor whose operating speed is or can be controlled as a function of an operating and/or used cooling space temperature signal of, the assigned or assignable refrigerator compressor.

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.

Disclosed is a refrigerator having a centrifugal fan with a volute, which includes a cabinet, an evaporator, a centrifugal fan, and an air supply duct. A cooling chamber located at a lower part and at least one storage compartment located above the cooling chamber are defined in the cabinet; the evaporator is disposed in the cooling chamber and is configured to cool airflow entering the cooling chamber to form cooled airflow; the centrifugal fan includes a volute and an impeller disposed in the volute; and the air supply duct is detachably connected with the volute, communicates with a volute air outlet, and is configured to deliver the cooled airflow into the at least one storage compartment. In the refrigerator of the present invention, the cooling chamber is located at a lower part of the cabinet, so that the cooling chamber occupies a lower space in the cabinet; the storage compartment is located above the cooling chamber, a compressor chamber may be defined behind the cooling chamber, and the storage compartment no longer needs to make room for the compressor chamber, thus guaranteeing the storage volume of the storage compartment. In addition, the air supply duct and the centrifugal fan adopt a split design, which implements modularization, is convenient for disassembly, assembly and transportation, and improves the yield rate.

A refrigerator may include a body formed with a storage space and a cooling module accommodating space; a cooling module disposed in the cooling module accommodating space and having a heat absorption part and a heat radiating part; a drawer supporter disposed inside the storage space; and a drawer supported by the drawer supporter, and the drawer supporter is formed with an inner passage through which cold air flowing from the heat absorption part passes, and the drawer supporter is formed with a plurality of cold air discharge ports through which cold air of the inner passage is discharged in an opposite direction. Therefore, it is possible to maximize the depth of the storage space in the front-rear direction while minimizing the number of parts, and cool the entire storage space evenly.

There is disclosed a refrigerator including an evaporator configured to generate cold air; and a grill fan assembly configured to blown the cold air generated by the evaporator to a freezer compartment and an ice-making chamber, wherein the grill fan assembly includes a freezing fan module; an ice-making fan module disposed in a predetermined area of the freezing fan module; a first cold air flow path guide disposed between the freezing fan module and the ice-making fan module; and a second cold air flow path guide disposed between the freezing fan module and the first cold air flow path guide, and the first cold air flow path guide and the second cold air flow path guide are spaced apart from an upper wall of the grill fan assembly.

A cooling unit for a data center comprises a fan section, a set of airstream diversion sections, and a set of cooling sections. The fan section is disposed at a front end of the unit. The set of airstream diversion sections includes one or more main airstream diversion channels and a rear airstream diversion channel. The airstream diversion section is configured to direct airflow from the fan section to the set of cooling sections. The set of cooling sections includes a main cooling section disposed at a side of the unit and a rear cooling section disposed at a rear end of the unit. Cooling modules may be arranged in series within each cooling section and among multiple cooling sections to manage a cooling fluid distribution corresponding to hot air inlets, to achieve more uniform temperature and better thermal management.

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.

A refrigerator includes a fresh food compartment and a mullion adjacent the fresh food compartment. The refrigerator further includes an evaporator compartment defining an exterior and an interior and containing an evaporator. The refrigerator also includes a duct in fluid communication with the evaporator compartment at a first end thereof and in communication with a second end adjacent an opening of the fresh food compartment. The duct has a first portion thereof that extends downwardly from the first end and a second portion extending through the mullion.

The method for controlling the refrigerator includes operating a first cooling cycle for cooling the first storage compartment to operate the compressor and operating a first fan for the first storage compartment, and switching the first cooling cycle to a second cooling cycle for cooling the second storage compartment to operate the compressor and operating a second fan when a stop condition of the first cooling cycle is satisfied. A temperature of each storage compartment is sensed at sampling time intervals in each cooling cycle. Further, a cooling power of the compressor is determined for each sampling time based on a sensed current temperature of the storage compartment, and the compressor is operated at the determined cooling power.

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.
