A ventilation unit (1) designed for installation and use at a refrigeration plant has a fan and a heat exchanger (3) arranged in series with the fan. The fan is designed and positioned with regard to the heat exchanger (3) so as it delivers, in operation, an air volume flow through the heat exchanger (3) and out from the ventilation unit. The fan is designed as a diagonal fan (2). The diagonal fan axially draws in the air volume flow during operation and blows it out diagonally at an angle relative to its axis of rotation (RA).

A refrigeration appliance comprises a fan mounting assembly mountable to a liner of a cabinet. The fan mounting assembly comprises a bracket, a first member of a first snap coupling on the bracket for receiving a corresponding second member of the first snap coupling on an evaporator coil cover, and a mounting flange having a first member of a snap lock extending from the bracket for mounting the fan mounting assembly to the liner of the cabinet. An evaporator coil cover for mounting to the fan mounting assembly comprises a second member of the first snap coupling allowing the evaporator coil cover to be coupled to the fan mounting assembly, and a first slot. An air tower assembly mountable to the fan mounting assembly through the first slot comprises a second member of a second snap coupling and a second member of a third snap coupling.

A method of energy conversion for a freezer includes providing liquid CO.sub.2 at a first pressure and at a first energy state to a first region for providing potential energy; expanding the liquid CO.sub.2 to a second pressure less than the first pressure, and to a second energy state less than the first energy state in a second region in fluid communication with the first region for providing kinetic energy for performing mechanical work in the second region; and exhausting the liquid CO.sub.2 as a CO.sub.2 snow at a third pressure less than the second pressure, and at a third energy state less than the second energy state from a third region in fluid communication with the second region.

A refrigerating appliance includes an evaporator for providing cooled air to a refrigerating compartment. An air tower defines an air channel for directing the cooled air from the evaporator to the refrigerating compartment. A plurality of air-directing guide vanes is positioned within the air tower and proximate a top of the air channel. The air directing guide vanes direct the cooled air from the air channel to define redirected air that is delivered in a direction toward an upper cool-air slot defined within the air tower. The redirected air from the air-directing guide vanes travels through the upper cool-air slot at substantially the same velocity as the cooled air entering the air-directing guide vanes. The redirected air is directed through the upper cool-air slot and toward at least one upper corner of the refrigerating compartment.

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 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.
