A refrigerator and a method of controlling a refrigerator are provided. The refrigerator may include a machine room defined in or at one side of a storage compartment, a base that defines a bottom surface of the machine room, a compressor seated on the base to compress a refrigerant, a condenser that condenses a refrigerant compressed in the compressor, the condenser being disposed on or at one side of the compressor, a drain pan disposed on the base to store condensed water generated in the condenser, and a fan assembly coupled to the base to generate an air flow within the machine room. The fan assembly may include a plurality of condensation fans.

A refrigerator may include a body formed with a storage space and a cooling module accommodating space; a cooling module disposed in the cooling module accommodating space and having a heat absorption part and a heat radiating part; a drawer supporter disposed inside the storage space; and a drawer supported by the drawer supporter, and the drawer supporter is formed with an inner passage through which cold air flowing from the heat absorption part passes, and the drawer supporter is formed with a plurality of cold air discharge ports through which cold air of the inner passage is discharged in an opposite direction. Therefore, it is possible to maximize the depth of the storage space in the front-rear direction while minimizing the number of parts, and cool the entire storage space evenly.

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 control method for a refrigerator and a refrigerator are provided. The refrigerator includes a compartment, an evaporator, and a heating module. The method includes: acquiring a current temperature of the compartment; and adjusting an operating power of the heating module according to the current temperature, so that the heating module heats the compartment to a target temperature according to the operating power, where different temperature ranges correspond to different operating powers.

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.

A domestic refrigerator (1) comprises a thermally insulated housing (2), a cold storage compartment (5) and a fresh food compartment (4) contained within the housing (2) and located on top of each other, a refrigerant circuit which comprises an evaporator (29) configured to directly cool the cold storage compartment (5), a first door leaf (18) for closing and opening the fresh food compartment (4), a second door leaf (19) for closing and opening the cold storage compartment (5), a divisional wall (17, 42) separating the cold storage compartment (5) from the fresh food compartment (5), and a air channel system (31, 32) which is configured to allow an air exchange between the cold storage compartment (5) and the fresh food compartment (4).

A method for controlling a refrigerator includes providing an initial input value to a heater configured to supply heat to an evaporator, performing a continuous operation of the heater based on the initial input value to increase a temperature of the evaporator to a predetermined temperature, determining a period of time taken to increase the temperature of the evaporator to the predetermined temperature, determining whether the period of time is within a reference period of time, operating the heater based on a first input value that is equal to the initial input value based on a determination that the period of time is outside of the reference period of time, and operating the heater based on a second input value that is less than the initial input value based on a determination that the period of time is within the reference period of time.
