Data learning server and method for generating and using learning model thereof

A method for controlling an air conditioner, the method comprising:

• obtaining a recommended temperature, which is a result obtained by applying a set temperature to a learning model;
• displaying the received recommended temperature;
• and
• setting the received recommended temperature in the air conditioner,
• wherein the learning model is a learning model learned using a plurality of set temperatures previously set in the air conditioner.

A user terminal controlling an air conditioner, the user terminal comprising:

• a display configured to display a screen;
• a communicator configured to communicate with an external device;
• an input receiver configured to receive a user input;
• and
• at least one processor configured to:
• control the communicator to transmit an artificial intelligence operation request signal corresponding to an artificial intelligence operation UI to the air conditioner in response to a user input signal depending on a user input selecting the artificial intelligence operation UI included in the screen being received via the input receiver, and
• control the display to display a recommended temperature in response to the recommended temperature set in the air conditioner, which is a result obtained by applying a current temperature of the air conditioner to a learning model depending on the artificial intelligence operation request signal, being acquired via the communicator.
