Where the cold air supplier comprises a heat exchanger producing cold air, a duct accommodating the heat exchanger and defining a flow path for air to pass through the heat exchanger, and a fan generating an air flow inside the duct. Where the heat exchanger comprises a tube in which a refrigerant flows and a fin coupled to an outer surface of the tube. Where the tube is eccentrically arranged to a side of the duct.

A refrigeration appliance includes a liner having a rear wall that is contoured to define a first vertical recess therein. A partition divides the compartment into an upper and a lower compartment and includes a first protrusion disposed in the first vertical recess in the liner. A first opening extends through the first protrusion and is aligned with the first vertical recess in the liner. A temperature control system is positioned in the upper compartment and includes a vertical partition. At least one lower opening extends through a front surface of the vertical partition and fluidly communicates with an upper end of the first vertical recess in the liner and the first opening extending through the partition. An evaporator fan is disposed in the lower compartment.

A refrigerator supporting rod for installing lighting device has a rod body, the rod body having an inner side surface facing toward the refrigerator and an outer side surface back toward the refrigerator, a heat insulating layer is provided between the inner side surface and the outer side surface, the inner side surface is provided with a lamp mounting groove extending in the longitudinal direction. According to the refrigerator supporting rod for installing lighting device, a lamp can be installed in an embedded mode to integrate the two, so that the probability of touching the lamp is reduced, and the likelihood of damage is reduced.

A refrigerator includes a cabinet configured to have an inner case in which a storage chamber is formed, a cooler configured to cool the storage chamber, a heating device configured to be spaced apart from the cooler and heat the storage chamber, a circulation fan configured to circulate air in the storage chamber, and a controller configured to operate the circulation fan when the heating device is operated.

According to an embodiment of the present disclosure, a method for controlling a refrigerator, the refrigerator including an ice mater including a first tray and a second try provided in a storage space and coupled to each other to define a ice chamber and a driving part that rotates the second tray, a first heater provided in the first tray to heat the first tray, a second heater provided in the second tray to heat the second tray, and an ejector provided below the second tray to press an external portion of the second tray to separate ice from the second tray when the second tray is rotated for ice separation, and a controller that controls operation of the ice maker, the method including starting ice making by supplying water to the ice chamber; heating the second tray by turning on the second heater during ice making; heating the first tray by turning on the first heater for ice separation after completion of ice making; and heating the second tray by turning on the second heater for ice separation.

A refrigerator includes a refrigerator cabinet, a fresh food compartment disposed within the cabinet, a freezer compartment disposed within the cabinet, an ice compartment disposed within the cabinet, and an electronic control system associated with the refrigerator and adapted to monitor and control the fresh food compartment, the freezer compartment and the ice compartment. The control system provides for energy efficient control and operation through various means, including by monitoring state of an ice maker associated with the ice compartment and controlling temperature within compartments of the refrigerator based on the ice maker state. A damper controls air flow between the fresh food and freezer compartments. The control system can direct heat to the damper if the damper becomes frozen.

A freezer and method of operating a freezer are provided with an adaptive defrost cycle. The freezer includes a controller that operates the freezer to: provide cooling to a cabinet via an evaporator during periodic operational cycles, monitor a time elapsed since a most recent defrost cycle, determine whether the time elapsed is greater than a current defrost interval, and perform a defrost cycle if so. The controller varies the current defrost interval between a first, larger time value and a second, smaller time value based on a plurality of trigger signals in response to various operating characteristics of the freezer monitored by sensors. After each defrost cycle is completed, the current defrost interval is reset to the first, larger time value.

A refrigeration appliance including a compartment for storing food items. A partition divides the compartment into a first and a second compartments. The first compartment is disposed horizontally adjacent the second compartment and has a user-selectable target freezer temperature. An evaporator is disposed in the first compartment. An evaporator fan is disposed in the first compartment for conveying cooling air from the evaporator to the first and the second compartments. A temperature control module positioned in the second compartment. The temperature control module includes a body having front and rear surfaces. An air passage is formed in the body and extends between a side inlet opening of the body to at least one outlet opening on the front surface of the body. A heater assembly is disposed between the front and the rear surfaces of the body for heating air in the air passage.

A refrigerator includes a cabinet configured to form a first storage chamber and a second storage chamber, a first evaporator configured to cool the first storage chamber, a first fan configured to circulate air in the first storage chamber to the first evaporator and the first storage chamber, a second evaporator configured to cool the second storage chamber, a compressor configured to be connected to the first evaporator and the second evaporator, a second fan configured to circulate air in the second storage chamber to the second evaporator and the second storage chamber; a refrigerant valve configured to guide refrigerant to the first evaporator or the second evaporator, and a controller configured to perform a plurality of modes sequentially to defrost the second evaporator.

A cryogenic cooling manifold and methods incorporating a cryogenic cooling manifold for managing the gas layer(s) above a liquid cryogen to control cooling temperature-time profiles and ice formation for microliter and smaller samples that are plunged through the gas and into the liquid cryogen.
