1. A method of controlling an air conditioner through processing of clusters of indoor unit data, the method comprising:
operating an indoor unit by generating control signals for a fan and an expansion valve based on initial environment data collected by an indoor sensing unit;
collecting indoor unit data, including at least temperature, humidity, and occupancy information, via the indoor sensing unit comprising one or more sensors;
matching, by a controller, the collected indoor unit data to one of a plurality of clusters stored in a storage, each cluster being associated with control parameter data used for operating the indoor unit;
re-collecting the indoor unit data at preset time intervals during an operating time of the indoor unit, and matching, by the controller, the re-collected indoor unit data to corresponding clusters;
controlling the indoor unit to be turned off after completion of an operating cycle;
analyzing, by the controller, variations in the clusters matched during the operating time of the indoor unit, and adjusting control parameter data associated with the clusters based on the analysis, wherein the adjusted parameters are stored in memory and used for updating control profiles corresponding to the clusters, wherein the plurality of clusters are classified into a plurality of cluster levels based on a load required for the indoor unit, and wherein the correcting of the clusters comprises, in response to a number of clusters, having a level greater than or equal to a preset level and counted during an operating time of the indoor unit, being greater than a preset percentage of a total number of the counted clusters, correcting the measured cluster levels to increase by one level; and
operating the indoor unit based on the adjusted control parameter data.
