<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of carrying out life-end processing at an appropriate time. <P>SOLUTION: A total elapsed time T1 which is the time elapsed from the time of manufacturing is measured. An energization integrated time T2 which is a time elapsed in an energized state from an external power source is measured. An operation integrated time T3 which is a time elapsed in an air-conditioning operated state is measured. A product state value P is computed based on the measured total elapsed time T1, the energization integrated time T2 and the operation integrated time T3. When the computed product state value P reaches a preset second set life value J2, life extending operation is performed, and when the computed product state value P reaches a preset first set life value J1, the system stop processing of the air conditioner is performed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
