Abstract: A method for controlling an air conditioner and an air conditioner are provided. The air conditioner may include a compressor that compresses a refrigerant; and a control unit that controls the compressor. The control unit may include a main control unit that controls an entirety of the air conditioner; a start-up control unit that controls the compressor at an initial start-up of the compressor; a normal control unit that controls the compressor according to a target room temperature after the start-up control unit completely controls the compressor; and a bumpless control unit that calculates a compensation value for lowering an operating frequency of the compressor according to an indoor load when a priority for controlling the compressor is transferred from the start-up control unit to the normal control unit. The bumpless control unit lowers the operating frequency of the compressor according to the compensation value.

Abstract: The present invention provides a method for controlling an air conditioner, the air conditioner comprising: a compressor that compresses a refrigerant; and a control unit that controls the compressor, wherein the control unit includes: a main control unit that controls the entirety of the air conditioner; a start-up control unit that controls the compressor when the compressor is operated; a normal control unit that controls the compressor according to a target room temperature after the start-up control unit completely controls the compressor; and a bumpless control unit that calculates a compensation value for lowering the operating frequency of the compressor according to an indoor load when a priority for controlling the compressor is transferred from the start-up control unit to the normal control unit, wherein the bumpless control unit lowers the operating frequency of the compressor according to the compensation value.

Abstract: The present invention relates to an air conditioner with an ionizer which comprises: an ionizer to generate ions mounted in the vicinity of an air outlet, a carrier to move the ionizer, and a controller to control the ionizer and the carrier. The controller controls the carrier to move the ionizer to an initial point when power is supplied to the air conditioner or the power is changed from turn off to turn on. The controller can control a position of the ionizer with the carrier in response to a sensing signal of a sensor which senses a position of a person. Accordingly, a range of ion diffusion can be controlled efficiently, and by making the ions to be discharged to a specific direction the user presents thereto, effective improvement of an ion effect the user feel can be improved.
