A cooling or heating device for cooling and/or heating fluids includes a housing and a plurality of cooling plates. The cooling plates are arranged inside the housing, and the cooling plates each comprise at least one cooling channel for guiding a cooling or heating medium through the cooling plates. A container support surface is provided for arranging at least one first container containing a fluid to be heated or cooled inside the housing, and there is a first air blower in the housing for blowing air onto the cooling plates and/or into spaces between the cooling plates.

The present disclosure relates to a refrigerator, and the refrigerator includes a cabinet, a first storage chamber and a second storage chamber configured to store food, and a grill pan assembly configured to partition the inner portion of the first storage chamber into a space in which an evaporator is provided, in which the grill pan assembly includes a grill pan forming a front surface of the grill pan assembly, a shroud on which a first fan and a second fan are mounted, a heat insulating member configured to be provided between the grill pan and the shroud and on which a first flow path part configured to supply the cold air forcibly flowing by the first fan to the first storage chamber and a second flow path part configured to supply the cold air forcibly flowing by the second fan to the second storage chamber are formed on the same surface, and a duct connector configured to be provided at a position corresponding to the second fan in a space between the shroud and the heat insulating member and connected to the second flow path part to form an independent flow path.

A refrigerator appliance includes a cabinet forming a refrigerating compartment defining a plurality of cooling zones, an air circulation duct in fluid communication with the refrigerating compartment, an evaporator provided in the air circulation duct, and a damper assembly in fluid communication with the air circulation duct and the refrigerating compartment. The damper assembly includes a plurality of doors to selectively allow air to enter into selected cooling zones within the refrigerating compartment.

The present disclosure relates to a refrigerator. The refrigerator is configured to supply cool air to a refrigerating compartment, a freezing compartment, and an ice-making compartment by a single evaporator. A cool air passage for the ice-making compartment for supplying cool air to the ice-making compartment is configured to supply the cool air to an upper space in a cool air passage for the freezing compartment, which. supplies cool air to the refrigerating compartment and the freezing compartment, through an upper supply passage. Accordingly, since additional cool air is supplied to the cool air passage for the freezing compartment by using the upper supply passage, sufficient cool air is supplied to the refrigerating compartment and the freezing compartment by the single evaporator.

The present disclosure relates to a refrigerator. Wherein a cool air passage for a freezing compartment, the cool air passage guiding the flow of cool air to the freezing compartment, and a cool air passage for an ice-making compartment, the cool air passage guiding the flow of cool air to the ice-making compartment, partially share the cool air thereof. Through the sharing of cool air, the amount of cool air supplied to the freezing compartment is increased and sufficient cool air is supplied to the refrigerating compartment. Accordingly, sufficient cool air is supplied to the refrigerating compartment, the freezing compartment, and the ice-making compartment even with a single evaporator.

A domestic refrigerator has a refrigeration compartment and a container which can be accommodated in the refrigeration compartment and has a lower part for receiving products to be refrigerated and a cover that can cover the lower part. The container has an air inlet opening and an air outlet opening that is at a distance from the air inlet opening. The domestic refrigerator also has a controllable air flow adjustment device and is configured to vary a volume flow rate of an air flow, which enters the container from the refrigeration compartment through the air inlet opening, between at least two values by adjusting an adjustment parameter of the air flow adjustment device. Furthermore, a method ventilates the container which is accommodated in the refrigeration compartment and has the air inlet opening and the air outlet opening.

A refrigerator may include: a refrigerator compartment, a convertible compartment, an evaporator disposed in the convertible compartment; and a grill pan assembly forming a space where the evaporator is disposed by dividing the inside of the convertible compartment. The grill pan assembly may include an insulating member, a convertible compartment fan, a refrigerator compartment fan, and an opening device formed at the insulating member from the convertible compartment channel to the refrigerator compartment channel.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

An in-refrigerator blower configured to drive cold air to refrigerator storage rooms with reduced vibration and reduced noise. The in-refrigerator blower includes a drive device, a drive device accommodation portion, and a support portion coupled to the drive device accommodation portion and configured to extend in a radial direction. A plurality of blades extend in a direction different from an extension direction of the support portion. Each of the blades has an entrance angle in the range of 39°-49°, an exit angle in the range of 29.5° to 34.5° in one example. The number of the blades is greater than seven and smaller than nine.

A refrigerator having an ice-making device evaporator in addition to a refrigerator storage room evaporator. The ice-making device includes an ice tray and a cooling pipe contacting an outer surface of the ice tray. A refrigerant flows in the cooling pipe and directly cools the ice tray. The ice-making device evaporator receives the refrigerant from a condenser and supplies it to the cooling pipe. A heat insulation member wraps around the cooling pipe and can prevent the cooling pipe from exchanging heat with ambient air.
