Abstract: Disclosed is an air conditioner. The air conditioner includes: an outdoor unit having therein a compressor for compressing refrigerant; at least one indoor unit; a storage configured to store a database on a power quantity used by the air conditioner; and a controller. The controller is configured to: based on the database, calculate an estimated power quantity expected to be used by the air conditioner for at least a part of an entire period, based on a preset maximum power quantity for the entire period and the calculated estimated power quantity, determine a target power quantity for a specific unit time, which is expected to be used by the air conditioner for the specific unit time of the entire period; control the compressor for the specific unit time based on the target power quantity; and in response to arrival of a point in time to update the target power quantity, add, to the database, the power quantity used by the air conditioner for the specific unit time.

Abstract: The present invention relates to a cleaner with a lightweight structure by integrating a discharge circuit line of a power supply line connected from a battery to a cleaning nozzle with a charge circuit line for charging the battery. According to embodiments of the present invention, there is an advantage that the lightweight of the cleaner can be achieved by integrating a discharge path and a charge path to a power supply line without being structurally distinguished, and since a discharge function and a charge function can all be performed on a circuit line of some sections of the power supply line, there is an advantage that the cost can be saved compared to implementing the charge and discharge circuits in separate structures.
