摘要： A refrigerator includes a compressor, a cold storage medium, a power supply to convert AC power supplied from an outside of the refrigerator, and to receive DC power during interruption of electric power, and a controller to perform a control operation to supply a cooling capacity to an interior of the refrigerator by driving the compressor based on the supplied AC power when no interruption of electric power occurs, and to perform a control operation to supply a cooling capacity to the interior of the refrigerator based on the supplied DC power and the cold storage medium during the interruption of electric power. Accordingly, consumption of electric power during interruption of electric power is reduced.

摘要： An appliance includes a driver to drive a load, the load requiring AC power or DC power. A power supply receives one of external AC power, back-up AC power and back-up DC power and outputs at least one of AC power or DC power to the load. An operation mode of the home appliance is one of normal operation when receiving external AC power, normal operation when receiving one of back-up AC power and back-up DC power during a power interruption, and a power save mode when receiving one of back-up AC power and back-up DC power during the power interruption. The power supplies a first power level when there is no power interruption, a second power level when there is power interruption and a third power level when there is power interruption and the power save mode is selected, where the second power level is between the first power level and the third power level. The power save mode is automatically selected when the second power level falls below a reference power level.

摘要： A refrigerator and a method for controlling the same are disclosed. A refrigerator includes a timer for measuring an interval of one hour after power is supplied to the refrigerator, a door opening/closing sensor for sensing opening and closing of a door, a storage unit for storing information whether door is opened in a sector defined as one hour by the timer and at least 7 sector units each having 24 consecutive sectors, and a control unit for predicting a refrigerator use pattern in 24 sectors by overlapping 7 sector units, performing a normal operation mode to maintain a storage compartment at a first desired temperature in a sector in which door opening is predicted, and performing a power-saving operation mode to maintain the storage compartment at a second desired temperature higher than the first desired temperature in a sector in which door opening is not predicted.

摘要： A linear compressor includes a cylinder, a piston, a linear motor configured to drive the piston, a current detection unit configured to sense a current in the linear motor, a relay configured to change an operation mode of the linear motor, and a control unit configured to set at least one parameter for determining a stroke of the piston according to the operation mode. The control unit is configured to: determine a first magnitude of a first current in the linear motor based on a state of the relay being in a first state, determine a second magnitude of a second current in the linear motor based on the relay being switched to a second state from the first state, compare the first magnitude to the second magnitude, and based on the comparison of the first magnitude to the second magnitude, determine whether the relay fails to operate.
