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 includes a housing body including an inner space of the refrigerator and a cooling cycle mechanism configured to cool the inner space. The housing body includes a plurality of housing body elements separated along a predetermined separate surface, and the plurality of housing body elements is removably coupled to each other to allow an end surface of one of the plurality of housing body elements to face an end surface of another one of the plurality of housing body elements. A sealing mechanism configured to form an air surface between opposite end surfaces is provided to prevent air from flowing into or from the inner space through between the opposite end surfaces.

A refrigerator includes a cooling/heating chamber capable of cooling and heating foods. The cooling/heating chamber is divided into a heating zone that is a space where foods to be heated are placed, and a non-heating zone that is a space continuous with the heating zone where foods not to be heated are placed. The refrigerator further includes an oscillation electrode and a counter electrode that are arranged so as to face each other with the heating zone in between, and an oscillating unit that applies an AC voltage to between the oscillation electrode and the counter electrode.

A showcase includes: a box-shaped case main body sectioned into a storage room and a machine room by a heat insulating bottom plate; article mounting shelves arranged in a plurality of stages in an up-and-down direction in the storage room; a circulating fan configured to circulate air from inside the storage room between the storage room and the machine room; and a cooler arranged in the machine room and configured to cool the air circulated by the circulating fan. The heat insulating bottom plate includes a first air inlet formed in a face facing the storage room, a second air inlet formed at a position that is in a face facing the machine room and does not overlap with the first air inlet in the up-and-down direction, and an inlet flow channel formed so as to cause the first and the second air inlets to communicate with each other.

A refrigerator includes a liner and a wall covering assembly to create a false wall within a refrigerator cabinet. The wall covering assembly includes a top wall spaced-apart from a top wall of the liner, and a rear wall spaced-apart from a rear wall of the liner. The rear wall of the wall covering assembly includes a ventilated portion for providing outwardly directed air to the refrigerator cabinet. A duct assembly is disposed between the wall covering assembly and the liner and is configured to deliver air through the ventilated portion of the wall covering assembly and also deliver air in the form of a downwardly directed air curtain at the front portion of the refrigerator cabinet. The air curtain disrupts the outward flow of air from the ventilated portion of the wall covering assembly at the front portion of the refrigerator cabinet.

A refrigerated sales furniture (2) comprises a base (4) provided at the bottom of the refrigerated sales furniture (2); a goods presentation space (10) comprising a front portion allowing access to the goods presentation space (10) and an opposing rear portion; wherein the goods presentation space (10) includes a bottom area (12) located next to the base (4); and a cold air channel (48) located next to the rear portion of the goods presentation space (10) comprising a lower portion (54) arranged next to the bottom area (12) of the goods presentation space (10) and having an opening (18) fluidly connecting the cold air channel (48) with the bottom area (12) of the goods presentation space (10) for allowing cold air to flow from the lower portion (54) of the cold air channel (48) into the bottom area (12) of the goods presentation space (10). The opening (18) is provided as a single opening (18) extending substantially over the whole height and width of the bottom area (12), respectively.

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.

A method for freeze protection for a temperature control system, and a temperature control system for controlling the temperature of a temperature-controlled space at a set point temperature. The method includes monitoring a discharge air temperature, monitoring a return air temperature, setting a target temperature to equal the set point temperature, controlling the return air temperature at the target temperature, and adjusting the target temperature based on the return air temperature when the discharge air temperature drops to one of at or below freezing.

A refrigerated storage unit 1 includes: a refrigeration chamber S2, a refrigeration part 3 for cooling air inside the refrigeration chamber S2, a fan 4 for sending cold air cooled by the refrigeration part 3 into the refrigeration chamber S2, a temperature sensor 5 for detecting a temperature inside the refrigeration chamber S2, an infrared sensor 8 for detecting a temperature of a content provided inside the refrigeration chamber S2, and a control part 7 for controlling driving of the fan based on a result detected by at least one of the temperature sensor 5 and the infrared sensor 8.

Disclosed is a refrigerator (100) preventing an air supply duct (141) from falling down, which includes a top cover (103) that divides a lowermost storage liner (130) into a storage space (132) located above and a cooling space located below, an evaporator (101) arranged in the cooling space, and the air supply duct (141) arranged at an inner side of a rear wall of the storage liner (130). The top cover (103) includes a top cover body (103a) and a supporting portion (103b) protruding upward from a rear end of the top cover body (103a); a bearing portion (141b) protruding forward is formed on a front wall surface of the air supply duct (141); and the top cover (103) and the air supply duct (141) are arranged such that the supporting portion (103b) supports the bearing portion (141b) to prevent the air supply duct (141) from falling down.
