<p>PROBLEM TO BE SOLVED: To provide an air conditioner including a function to notify a user of turning point time (absence time) of a turning point as to which is energy saving operation, the stop of an air conditioner in use or the continuation of operation if the user temporarily leaves a room.SOLUTION: Electric energy calculation means 33 calculates unit time electric energy that is electric energy of an air conditioner 1 per preset unit time since the air conditioner 1 starts operating on the basis of current consumption detected by current detection means 34, and outputs the calculated unit time electric energy to electric energy storage means 46. The electric energy storage means 46 stores starting electric energy that is initial unit time electric energy after the air conditioner 1 starts operating and stationary electric energy that is latest unit time electric energy after calculation of the starting electric energy. Turning point calculation means 47 transmits a value calculated by multiplying a ratio of the starting electric energy to the stationary electric energy by the unit time and subtracting the unit time from a multiplication result to notification means 48 as turning point time when advice request data is input to the turning point calculation means 47.</p> |
