A refrigeration cabinet has an insulated body comprising a rectangular base with an upstanding front wall, rear wall and end walls interconnecting the front wall and rear wall. The body forms an open-topped product chamber. A clear glass or clear plastics lid is mounted by hinges at a top of the rear wall to close the product chamber whilst at the same time allow customers to view chilled or frozen merchandise on display within the product chamber. At one end of the body a refrigeration unit is provided for generating a climate control cold air stream for circulation through the product chamber in order to maintain the merchandise in the product chamber in a chilled or frozen condition as required. An air distribution insert is demountably secured in the product chamber and cooperates with an inner liner of the insulated body to form air circulation ducts for delivery of the cold air stream generated by the refrigeration unit to and from the product chamber to circulate the climate control cold air stream through the product chamber in a controlled manner between a bottom and a top of the product chamber.

Systems and methods are disclosed herein that include providing a cooler with a supply duct, a plurality of shelf plenums connected in fluid communication with the supply duct, and a return duct to implement precise temperature control over an internal cooling space of the cooler. Each of the shelf plenums may include openings disposed in a top surface of each shelf plenum. A supply airflow generated by a fan of a refrigeration system may pass the supply airflow through the supply duct to each of the plurality of shelf plenums, where the supply airflow may exit the shelf plenums through the openings in each shelf plenum to directly contact beverages and/or food products disposed on the top surface of the shelf plenums. The cooler may be further operated to supercool liquid beverages below a freezing point of the beverages without causing solidification and/or crystallization of the beverages.

A refrigerator is wall-mounted. The refrigerator has a frame with an insulated compartment supporting a plurality of shelves, a front panel covering the frame and having at least one window for displaying refrigerated articles supported by the shelves, at least one door to access the articles supported by the shelves, a cooling unit, an air recirculation system having a warm air collector for collecting warm air and having a warm air channel for directing air through the cooling unit to provide cooled air, at least one fan, and a cold air channel for directing the cooled air back into the compartment and a mounting for anchoring the refrigerator with respect to a wall. The thermal efficiency of the refrigerator may be enhanced as described herein.

The invention is a refrigerator with a detachable heat exchange unit, and includes a refrigerator body 11 having upper openings 23 on the top or lower openings 30; a heat exchange unit 13 provided on the upper surface or the lower surface of the refrigerator body 11; a base plate 18 on which the heat exchange unit 13 is mounted, is detachably attached on the refrigerator body 11; and an evaporator box 21 mounted on the base plate 18, enclosing the evaporator 7 and having box openings 24 on the floor corresponding to the upper openings 23 or the lower openings 30 of the refrigerator body 11.

The present invention relates to a cover 100 for cooling fins 4 disposed in an interior space 3 of a refrigerator 1. The cover comprises an inlet portion 101 comprising at least one inlet 102, wherein said inlet portion 101 is adapted such that an air flow is allowed to enter through said inlet 102. The cover 100 further comprises an outlet portion 103 comprising at least a first outlet 104, 105, wherein said first outlet 104, 105 is arranged relative to said inlet 102 such that said air flow is able to exit through said first outlet 104, 105. The first outlet 104, 105 is configured such that said air flow exiting through said first outlet 104, 105 is directed to at least a first volume 5 in said interior space 3 of said refrigerator 1. The invention is further directed to a refrigerator 1 for a vehicle having an inventive cover 100.

The present invention provides a refrigerator, comprising a storage compartment and a mixed air passage. Both ends of the mixed air passage have air inlets, the middle portion of the mixed air passage comprises a mixed air outlet communicating with the storage compartment, and the mixed air passage is configured to receive air flows from the two air inlets such that two air flows enter the storage compartment in a mixed manner via the mixed air outlet. The refrigerator of this invention comprises a mixed air passage, so that the air in an area of the storage compartment with a relatively high temperature can enter the mixed air passage earlier than external air or the air in the storage compartment with a relatively low temperature. Then, the two air flows are blown to the storage compartment in a mixed manner, realizing even temperature distribution in the storage compartment.

A drug refrigerator capable of temperature control with a small fluctuation range in interior temperature is provided. This is the drug refrigerator in which cold air in a cooling chamber partitioned by a vertical partition plate in the back of an interior is circulated into the interior by a fan. A cold air inlet is formed above the center of the vertical partition plate. At right and left positions lower than a cooler in the cooling chamber, forward-facing cold air outlets are provided. A downward-facing cold air outlet for blowing out cold air toward a bottom part of the interior is provided at a position lower than the forward-facing cold air outlets. The circulation amount of cold air blown out through the forward-facing cold air outlet is made larger than the circulation amount of cold air blown out through the downward-facing cold air outlet.

A refrigerator a duct arranged to partition an inner space of a storage chamber body into a storage chamber and an air flow channel, wherein the duct has an ejection hole defined therein; a roll-bond evaporator disposed in the air flow channel, wherein the roll-bond evaporator has a top and a bottom, a left end and a right end; a blowing fan configured to draw air from the storage chamber to blow the air into the air flow channel; and a defrost sensor closer to one of the top and bottom than the other of the top and the bottom, wherein said one is closer to the blowing fan than the other, wherein the sensor is closer to one of the left end and the right end than the other of the left end and the right end.

The present invention relates to an apparatus capable of purifying air and maintaining freshness inside a refrigerator while minimizing deformation of the structure of an existing refrigerator, and a method for controlling the same. The apparatus for air purification and freshness maintenance according to the present invention is formed separately from a storage space (12) of a refrigerator (10) and is installed on a cooling passage (14) which communicates with the storage space (12) through an inlet (13) and an outlet (15), wherein a photocatalyst filter (30) is installed in the vicinity of the outlet (15) within the cooling passage (14), and a plurality of cells (32) forming an air vent are formed in the photocatalyst filter (30) in the same direction as the air flow direction within the cooling passage (14), in which a UV LED (41) for radiating ultraviolet rays toward the cells (32) of the photocatalyst filter (30) is installed.

The present disclosure relates to a refrigerator and a fan assembly for a refrigerator. In accordance with one aspect of the present disclosure, there may be provided a refrigerator, including a main body having one or more storage spaces, one or more doors configured to open or close at least part of the one or more storage spaces, a cool air supply device configured to supply cool air to maintain the storage space at a predetermined temperature, food storage separators configured to partition the one or more storage spaces and store food, and a fan assembly in the one or more storage spaces configured to circulate air in the one or more storage spaces.
