Abstract

An air conditioner management system and a method for controlling an air conditioner are disclosed. A user interface device provides a user interface to sense a user measure indicating a user opinion regarding operation of an air conditioner, generates feedback data associated with the sensed user measure, and transmits the generated feedback data. A central management device receives and stores the feedback data transmitted by the user interface device and calculates a set value to control the air conditioner based on the received feedback data and previously stored feedback data.
