An air cleaning system can rapidly senses occurrence of local pollution, caused by fine dust, through a remote sensor hub and supplies purified air to a polluted area in a concentrated manner, thereby quickly purifying indoor air.

Air cleaning system

A flow generator according to an embodiment of the present invention includes an upper fan configured to suction upper air and generate a first airflow, an upper fan housing configured to accommodate the upper fan from a lower side thereof and comprising a first discharge part through which the suctioned upper air is discharged, a lower fan configured to suction lower air and generate a second airflow, a lower fan housing configured to accommodate the lower fan from an upper side thereof and comprising a second discharge part through which the suctioned lower air is discharged, an air guide disposed between the upper fan and the lower fan to guide generation of a third airflow in which the first airflow and the second airflow are mixed with each other, and a control unit configured to control a rotational speed of the lower fan or the upper fan to adjust a discharge direction of the third airflow, wherein the first discharge part is disposed to face the second discharge part with respect to the flow guide part.

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.

Method for controlling air conditioner

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.
