The ice maker includes an ice mold with an upper surface comprising a plurality of cavities formed therein for the ice pieces, a heater disposed on the ice mold and an ice maker refrigerant tube abutting at least one lateral side surface of the ice mold and cooling the ice mold to a temperature below 0° C. via thermal conduction.

A refrigerating apparatus may include a main body having an interior space in which an article is accommodated, a door configured to open and close an opening of the main body, a compressor configured to compress a non-azeotropic mixed refrigerant, a condenser configured to condense the compressed non-azeotropic mixed refrigerant, a hotline provided at a contact portion between the main body and the door through which the condensed non-azeotropic mixed refrigerant flows, an expander configured to expand the non-azeotropic mixed refrigerant, heat of which is radiated by the hotline, and an evaporator configured to evaporate the expanded non-azeotropic mixed refrigerant to supply cold air to the interior space. According to such structure, even when the non-azeotropic mixed refrigerant is used, a function of the hotline to prevent dew formation may be normally performed with hot refrigerant.

A refrigerator and method utilize a pair of tandem evaporators to provide cooling for both a compartment and an ice making system of a refrigerator. An upstream evaporator in the pair of tandem evaporators provides cooling for a compartment such as a freezer, fresh food, flexible cooling, or quick cooling compartment, while a downstream evaporator is in fluid communication with the upstream evaporator to receive a portion of the air cooled by the upstream evaporator and further cool the received portion for use in cooling one or more components of the ice making system.

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.

In an air composition adjustment device configured to adjust composition of air in a target space, an air circuit configured to supply air having adjusted composition to the target space is provided with a first passage through which outside air is introduced into an adjuster, and a second passage which is branched from the first passage and through which outside air is introduced into the sensor, and the second passage is provided with a moisture removal portion configured to remove moisture in air introduced into the sensor. This reduces a risk of a failure of the sensor due to contact of the sensor with moisture passed through the passage introducing outside air into the sensor.

An artificial intelligent refrigerator is disclosed. The artificial intelligent refrigerator includes: one or more first temperature sensor that senses refrigerating compartment-internal temperature in a refrigerating compartment of the refrigerator; one or more second temperature sensor that senses freezing compartment-internal temperature in a freezing compartment of the refrigerator; and a refrigerator processor that calculates a load accumulation amount for food put in the refrigerator on the basis of the refrigerating compartment-internal temperature or the freezing compartment-internal temperature, and performs a load correspondence operation using the calculated load accumulation amount. According to the artificial intelligent refrigerator of the present disclosure, one or more of a user terminal, and a server of the present disclosure may be associated with an artificial intelligence module, a drone ((Unmanned Aerial Vehicle, UAV), a robot, an AR (Augmented Reality) device, a VR (Virtual Reality) device, a device associated with 5G services, etc.

A refrigerator includes a main body defining a storage space, a cryogenic freezing compartment having an insulation space that is independent with respect to the storage space, an evaporator disposed inside the storage space to cool the storage space, and a thermoelectric module assembly disposed at one side of the cryogenic freezing compartment so that the cryogenic freezing compartment is cooled to a temperature less than that of the storage space. The thermoelectric module assembly includes a thermoelectric module, a cold sink coming into contact with a heat absorption surface of the thermoelectric module and disposed in the cryogenic freezing compartment, and a heat sink coming into contact with a heat generation surface of the thermoelectric module. The heat sink is cooled by introducing a refrigerant supplied to the evaporator.
