Abstract: A refrigerator is provided that includes a fan that blows cool air generated by an evaporator to a freezing chamber or a refrigerating chamber; a scroll guide that discharges cool air discharged from the fan in two directions; a guide pipeline formed at the scroll guide in two directions, that guides cool air discharged from the scroll guide; and a cool air duct connected to the guide pipeline, that supplies cool air to the freezing chamber or the refrigerating chamber. An optimum scroll guide that can be applicable even when a plurality of cool air ducts are implemented is provided, thereby reducing a flow loss of cool air discharged from the fan and decreasing power consumption.

Abstract: There is a cooling system and method for its use that cools carcasses prior to their being placed into cold storage units, such as refrigeration units or freezers. The cooling system includes cooling units having a wall therein, to redirect airflow in a circular pathway from a first side of the wall to a second side of the wall. The cooling unit includes at least one cooling apparatus positioned proximate the first side of wall, for directing airflow of cooled air produced in the cooling apparatus, vertically downward in a direction toward the floor, and over the animal carcass. The wall is above the floor, such that this cooled air moves from the first side of the wall to the second side of the wall, and completes the circular pathway by returning to the area proximate to the cooling apparatus. An apparatus for creating condensation can be placed on the second side of the wall, such that condensation falls to the floor, and not into contact with the animal carcasses.

Abstract: A flash freezer and process is described in which a freezer cabinet is configured to be positioned within the refrigerated air compartment of a primary freezer. An internal flash freeze compartment is located within the cabinet next to a plenum which is separated from the flash freeze compartment by a bulkhead. A plurality of first air passage apertures is formed through the bulkhead to permit passage of air between the flash freeze compartment and the plenum. A plurality of second air passage apertures is formed through a cabinet wall opposite to the bulkhead. The air passage apertures are arranged to control passage of refrigerated air under pressure from the refrigerated air compartment to direct a uniform pressurized airflow through the flash freeze compartment and over the articles placed therein.

Abstract: A cooling air circulating device of a refrigerator is provided. According to the cooling air circulating device, it is possible to impartially cool a chilling chamber and to make the spread of temperature of the chilling chamber uniform by letting cooling air sucked up into the respective cells divided by shelves of the chilling chamber. Also, it is possible to rapidly cool the chilling chamber and to reduce time for cooling the chilling chamber by minimizing time, for which the cooling air whose temperature has risen above a predetermined temperature stays in the chilling chamber.

Abstract: A intended in particular for equipping a tunnel for refrigeration of products such as food products, wherein this tunnel has a gaseous current flowing through it. The fan includes at least one pair of funnels (1) fixed onto one face of a support (2) mounted so that it can rotate about a vertical axis (XX) and connected to a device for driving rotation. The funnels have their entrance apertures (4) arranged radially so as to allow the gaseous current to penetrate into them and to emerge from them at an accelerated speed via their exit aperture (S). One or several fans [according to the invention] can be arranged at appropriate places in the tunnel, their rotation speed being chosen so that the exit gas currents from the funnels ensure a high degree of heat transport while reducing the risk of undesirable movement of products passing by on a conveyor placed below the fans.

Abstract: The present invention relates to a method and device for use in a refrigeration unit, whereby the invention causes air to flow in a circular motion whereby the air flows in an initial downward arc before flowing upward. Importantly, the present invention relates to the implementation of a wall in a refrigeration unit to cause the air to circulate in the desired motion, with such flow reducing condensation on the ceiling of the refrigeration unit and cooling animal carcasses in the refrigeration unit at a faster rate.

Abstract: Containers for transportation of bulk cargo susceptible to spoilage, that have a controlled temperature profile. The refrigerated containers include opposed insulated side walls each of which include internal channels for carrying return air from the floor of the container upward into a plenum. Each plenum is closed at one end, and in fluid communication with a refrigeration unit at the other end to supply return air to the refrigeration unit. Refrigerated air is blown from the refrigeration unit into a central air distribution duct that extends longitudinally along the roof of the container. The central duct is supplied with a multiplicity of spaced apart apertures, and is preferably tapered from a widest point in the vicinity of the refrigeration unit. Thus, substantially equal refrigerated airflow can be obtained throughout the refrigerated container.

Abstract: A large-volume shipping container has a pair of upright and spaced side walls and a floor extending between lower edges of the side walls and formed with at least two groups of full-length passages upwardly open at respective full-length slots. In accordance with the invention the passages of one of the groups has a flow cross section different from the passages of the other group. A roof extends between upper edges of the side walls, a rear end door wall extends between rear edges of the roof, floor, and side walls, and a front end wall extends between front edges of the roof, floor, and side walls and defines with the roof, floor, and other walls a closed cargo-containing space. A refrigerating apparatus in the front end wall forces cool air into front ends of the passages to distribute the cool air through the space differentially according to the flow cross sections of the passages.
