Samsung patents air conditioner that lowers power use by slowing the compressor

This patent describes an air conditioner that lets users choose a specific power-saving level. The device calculates how hard the compressor needs to work to reach the desired temperature, then reduces that speed based on the user's selected saving rate.

Why it mattersIt offers a straightforward way for homeowners to balance cooling comfort with electricity costs by manually adjusting the unit's efficiency.

In the filing’s own words

An air conditioner includes a compressor; an input unit to receive a target temperature and a power saving command including a power saving rate; an indoor temperature detection unit to obtain a room temperature; and a control unit to control so that the operating frequency of the compressor is determined based on the difference between the received target temperature and the obtained room temperature, the operating frequency is changed according to the power saving rate, and the compressor is driven with the changed operating frequency.

What exactly they claim (claim 1)

1. An air conditioner comprising: a compressor; an inputter configured to receive at least one of a target temperature and a power-saving command from a user, a power-saving command including a plurality of power-saving rates for adjusting an operating frequency of the compressor; a temperature detector configured to measure a room temperature; and an integrated controller configured to: set a normal operating frequency of the compressor based on a difference between the received target temperature and the measured room temperature; control the compressor to drive at the normal operating frequency; in response to receiving the power-saving command, adjust the normal operating frequency based on a constant value corresponding to one of the plurality of power-saving rates included in the power-saving command; and control the compressor to drive at the adjusted operating frequency.
