A method of controlling a refrigerator includes starting a first cooling cycle to cool a first storage compartment by operating a compressor and a first fan, determining whether a start condition of a second cooling cycle to cool a second storage compartment is satisfied, operating a second fan for the second storage compartment when the start condition of the second cooling cycle is satisfied, determining whether an output change condition of the second fan is satisfied while the second fan operates, and changing a speed of the second fan when the output change condition of the second fan is satisfied.

This disclosure relates to a system and method to improve the uniformity of the heat transfer coefficient of containers filled with biological materials during the freezing and thawing process, in particular a system that is easily transported and incremented to other conventional freeze-thaw methods and equipment. The system includes a portable air blast system configured to receive a container filled with biological materials and to be placed in a cooling or heating chamber, for homogeneous and reproducible freezing and thawing of biological materials. This disclosure also relates to a method of freezing and thawing biological solution inside a container by using the portable air blast system according to any of the previous claims 1-12, comprising: obtaining a container filled with biological solution; placing the container into the vent enclosure and on the stand of the air blast system; placing the air blast system with the container into a heating or cooling chamber; activating the air blast system by activating the fan in the air blast system.

A refrigerator appliance assembly includes a cabinet having at least one chamber for receipt of an item, a door permitting access to the at least one chamber, a temperature port within the at least one chamber, and a temperature probe communicatively coupled with the temperature port. The temperature probe is configured to generate one or more first temperature signals representative of an actual temperature of at least one of the item or the at least one chamber. The refrigerator appliance also includes a controller communicatively coupled to the temperature probe. Thus, upon receipt of the one or more first temperature signals, the controller determines the actual temperature of at least one of the item or the at least one chamber. Further, the refrigerator appliance also includes a user interface communicatively coupled to the controller. Accordingly, the user interface displays the actual temperature to a user and allows the user to adjust the actual temperature of at least one of the item or the at least one chamber to a desired temperature of the item.

Provided is a vacuum adiabatic body. To reduce a heat transfer amount between two plates, the vacuum adiabatic body includes: a conductive resistance sheet connecting plate members to each other, an exhaust port through which a gas of a third space is exhausted, and a sealing frame covering a conductive resistance sheet. A virtual line connecting both end portions of the conductive resistance sheet to each other is installed to be obliquely inclined when at least one extension direction of a first plate member or a second plate member is viewed in a horizontal direction.

A refrigerator according to an embodiment of the present disclosure includes a first storage compartment, a cavity, a heat source, a cold source, a water molecule freezing preventing device, and a controller configured to control an output of at least one of the heat source, the cold source, or the water molecule freezing preventing device, wherein the controller is configured to perform a first operation step to operate based on the first notch temperature for a cooling operation, a second operation step to operate based on a second notch temperature for a heating operation, and a third operation step to operate based on a third notch temperature for the cooling operation, the second notch temperature is higher than 0° C., cold in the first storage chamber increases in the first operation step and the third operation step, and the cold decreases in the second operation step.
