Indoor unit for air conditioner and control method thereof

Abstract

Provided is an indoor unit for an air conditioner buried in a ceiling and including a heat exchanger with respect to an indoor space defined by a bottom surface, the ceiling, and a plurality of wall surface, including: a front panel where a suction part suctioning air of the indoor space; a discharge hole placed on at least one side of the suction part and discharging heat-exchanged air from the heat exchanger; an opening member provided movably to selectively open the discharge hole; a distance sensing unit sensing at least one of a distance up to the bottom surface from the front panel or the indoor unit and a distance up to the wall surface from the indoor unit; and a controller controlling the opening degree of the opening member based on a sensing result sensed by the distance sensing unit.

Description

technical field [0001] Exemplary embodiments of the present invention relate to an indoor unit for an air conditioner and a control method thereof. Background technique [0002] In general, an air conditioner as a cooling / heating system is a device that forms a refrigeration cycle consisting of a compressor, a condenser, an expansion device, and an evaporator, where the cooling / heating system draws in indoor air to exchange heat with a refrigerant , and then discharge the heat-exchanged air into the room. [0003] Air conditioners are classified into a split type air conditioner in which an outdoor unit and an indoor unit are installed separately, and an integral type air conditioner in which an outdoor unit and an indoor unit are integrally installed. [0004] In recent years, a multi-type air conditioner in which a plurality of indoor units are connected to one outdoor unit and installed in different indoor spaces has been widely used. [0005] Split air conditioners inc...
