Abstract: A mobile terminal, an operating method thereof, and a refrigerator are disclosed. The operating method of the mobile terminal includes receiving state information of the refrigerator from the refrigerator, displaying the state information of the refrigerator on a screen, and transmitting a control signal based on a control operation to the refrigerator. Therefore, it is possible to readily control the refrigerator using the mobile terminal.

Abstract: Provided is a component for a network system. The component for a network system which is communicable with the other component includes a communication unit for communicating with the other component, an input part for inputting a command related to an operation of the component, and a control part for controlling the operation of the component. The component includes a power saving function in which the component is operable on the basis of energy information.

Abstract: Provided are a component for network system and a method of controlling the same. The method includes: inputting a driving factor of the component or the other component; and predicting result information when the component or the other component is driven based on the inputted driving factor.

Abstract: A mobile terminal includes a wireless communication unit for collecting external information or transmitting recommended operation information to a home appliance, and a controller for generating the recommended operation information for the home appliance based on the collected external information. The mobile terminal may provide customized recommended operation information for each home appliance without separately including a device for controlling one or more home appliances provided in a home.

Abstract: A component in a network system includes an energy consumption component capable of communicating with a home area network and capable of consuming an energy generated from an energy generation unit of a utility area network, and the energy consumption component including at least one control unit to drive the energy consumption component; and a communication module to allow communication between the energy consumption component and an external component constituting the utility area network or the home area network, wherein the communication module is disposed on a path through which a power is supplied to the at least one control unit.

Abstract: Provided is a method of controlling a network system. In the method, power information and time information regarding an operation of an electric product is recognized. Then, an energy-saving operation mode is provided to the electric product or the electric product is operated in the energy-saving operation mode for reducing an energy-related value based on the reccognized power information and the time information.

Abstract: Provided is a network system, which includes an advanced metering infrastructure, a communication device, and an energy management system. The advanced metering infrastructure is configured to measure energy supplied from a power supply source. The communication device is configured to communicate energy information related with the energy. The energy management system recognizes the energy information to control driving of an electric product. The energy management system limits a function of at least one part of power consumption units constituting the electric product, based on whether the recognized energy information is an on-peak time period. Thus, the concentration of power consumptions can be removed, so that a power supplier can effectively manage power consumptions and a consumer can save electricity costs and energy.

Abstract: Provided is a method of controlling a network system. The method includes recognizing power information and an operation mode of an electric product, and providing an energy-saving operation mode to the electric product or operating the electric product in the energy-saving operation mode for reducing an energy-related value based on the recognized power information and the operation mode of the electric product.
