Abstract: Provided is a vacuum adiabatic body. The vacuum adiabatic body includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

Abstract: A vacuum adiabatic body between a first space and a second space includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

Abstract: Provided is a water purifier. The water purifier includes an agitator configured to agitate cooling water and heat-exchange the cooling water with a cooling coil, a motor coupled to the agitator to allow the agitator to rotate, the agitator operating at at least two rotational speeds other than zero, and a control assembly configured to control the rotational speed of the motor.

Abstract: A vehicle, a refrigerator for a vehicle, and a method for controlling a refrigerator for a vehicle are provided. The method for controlling the refrigerator for the vehicle includes turning on a switch of the refrigerator for the vehicle, measuring a temperature of an interior of the refrigerator for the vehicle a first time, measuring a temperature of the interior of the refrigerator for the vehicle again a second time after a predetermined time has elapsed from the first time, determining a temperature change of the interior of the refrigerator from the first time to the second time, and operating the refrigerator for the vehicle in a quench mode in which the temperature in the interior of the refrigerator is rapidly lowered, unlike a normal mode, if the temperature change in the interior of the refrigerator is in a positive direction.

Abstract: Provided is a refrigerating or warming apparatus. The refrigerating or warming apparatus may include a cavity or compartment of which at least a portion of a wall is provided as a vacuum adiabatic body, a machine room disposed at a side outside the cavity, a compressor accommodated in the machine room to compress a refrigerator, a first heat exchange module or assembly accommodated in the machine room to allow the refrigerant to be heat-exchanged, a second heat exchange module or assembly accommodated in the cavity to allow the refrigerant to be heat-exchanged, and a machine room cover which covers the machine room to separate air flow passages where an internal air flow and an external air flow have directions opposite to each other.
