System and method for controlling air conditioner

A system for controlling a plurality of air conditioners of a painting process line including an air conditioning equipment having the plurality of air conditioners, spray booth, and exhaust equipment that are divided into a plurality of zones, the system comprising:

• an outdoor air measuring device configured to measure temperature and humidity of outdoor air flowing into the plurality of air conditioners;
• an indoor air measuring device configured to measure temperature and humidity inside each of the zones of the spray booth;
• the plurality of air conditioners including controllers, wherein each of plurality of air conditioners is disposed in each of the zones of the air conditioning equipment and configured to supply heated air according to temperature and humidity stabilization conditions required for a painting process of each of the zones of the spray booth;
• a plurality of air conditioning controllers connected to the plurality of air conditioners and configured to transmit operation information related to the plurality of air conditioners including the temperatures and humidities measured by the outdoor air measuring device and the indoor air measuring device and to operate the plurality of air conditioners when a control value is received;
• and
• a server connected to the plurality of air conditioning controllers and configured to learn operation information history of the plurality of air conditioners collected through the air conditioning controllers to accumulate the learned data in a database and to extract the control value for each of the controllers of the plurality of air conditioners according to an initial operation condition of the plurality of air conditioners from the learned data in the database to control each of the controllers of the plurality of air conditioners for a predetermined time period based on the extracted data.
