A refrigerator to be installed in a storage space defined by a wall of an object includes a contact mechanism so that the refrigerator makes contact with the wall, and thus the refrigerator can be installed.

A cooling system having a cooling chamber including a surface defining one or more openings. A surface is configured to hold at least one container. An access door provides access to the cooling chamber. A refrigeration system is configured to cool the cooling chamber by forcing cool airflow through the one or more openings in the surface. The airflow through each of the one or more openings may be similar.

A refrigerator may be installed in a storage space defined by a wall of an object and includes a contact mechanism to bring the refrigerator into contact with the wall.

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.

A refrigerator includes a first inner case, a second inner case, a third inner case having a larger size than the first and second inner cases, a first evaporator and a first cooling fan disposed inside the first inner case, a second evaporator and a second cooling fan disposed inside the second inner case, a duct in which a first inlet portion communicating with an inside of the first inner case, a second inlet portion communicating with an inside of the second inner case, an outlet portion communicating with the third inner case, a first conduit for guiding, to the outlet portion, cold air blown from the first cooling fan from the first inlet portion, and a second conduit for guiding, to the outlet portion, cold air blown from the second cooling fan from the second inlet portion are formed, and a damper communicating with the outlet portion.

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.

In order to prevent condensation from forming on a surface of an outer gasket surrounding a rear surface of an outdoor side door of an entrance refrigerator, the entrance refrigerator has a flow passage structure in which a portion of indoor air, whose temperature is increased by heat exchange with a heat sink, flows along the surface of the outer gasket.

A method of reducing a temperature of at least one item including: transporting the at least one item on a moving substrate within an enclosure, the enclosure including at least one impingement apparatus; providing a coolant to at least one of a high pressure zone or a low pressure zone of the enclosure; circulating the coolant through the high and low pressure zones using a variable-speed gas circulation device of the impingement apparatus; directing impingement jets through openings in at least one impinger of the impingement apparatus toward the moving substrate disposed within the low pressure zone; and intermittently performing an operation on the at least one impingement apparatus during said transporting including: (i) reducing a speed of the variable-speed gas circulation device; (ii) vibrating the at least one impinger; and (iii) increasing the speed of the variable-speed gas circulation device.
