Abstract
An air conditioner and a controlling method thereof are provided. The controlling method may include determining an initial operation temperature based on a received external input or setting, cooling or heating a room at the determined initial operation temperature for a preset initial operation time period, and thereafter increasing or decreasing the room temperature at a preset time interval.
Claims15
A controlling method of an air conditioner, the method comprising:
- receiving an externally input temperature;
- determining an initial operation temperature based on the received externally input temperature or a preset program temperature;
- cooling or heating a designated space at the determined initial operation temperature for an initial operation time period;
- and
- after the initial operation time period has elapsed, cooling or heating the designated space to a comfort temperature, wherein the externally input temperature is a temperature between the initial operation temperature and the comfort temperature in both a cooling operation and a heating operation of the air conditioner,
- wherein cooling or heating the designated space to a comfort temperature comprises incrementally increasing or decreasing a room temperature to the comfort temperature, comprising:
- increasing or decreasing a current temperature by a preset temperature interval and re-setting the current temperature accordingly;
- cooling or heating the designated space at the re-set current temperature for a preset time interval, including increasing the preset time interval each time the current temperature is increased or decreased such that a current time interval is greater than a previous time interval;
- and
- repeating the increasing or decreasing and the cooling or heating steps until the room temperature reaches the comfort temperature.

A controlling method of an air conditioner, the method comprising:
- determining a desired temperature based on an external input or a preset program;
- performing an intensive cooling or heating operation to change a temperature of a designated space by a predetermined amount within a predetermined period of time;
- and
- thereafter performing an adaptive cooling or heating operation to incrementally change the temperature of the space over corresponding increments of time based on previously stored usage data or the preset program, comprising:
- determining an initial operation temperature that is less than the desired temperature and cooling the space at the determined operation temperature for a corresponding operation time period;
- after the corresponding operation period has elapsed, increasing the operation temperature by a predetermined interval and re-setting the operation temperature, and cooling the space at the re-set operation temperature for a corresponding operation time period;
- and
- continuing to incrementally increase the operation temperature by the predetermined interval and cool the space at the re-set operation temperature for the corresponding operation time period until the operation temperature reaches a comfort temperature that is greater than the initial operation temperature,
- wherein a duration of a current operation time period is greater than a duration of an immediately previous operation time period.
