<P>PROBLEM TO BE SOLVED: To provide a technology that can reduce cost for a nonvolatile storage medium, and efficiently collect data necessary for investigating the cause of a failure occurred in the storage medium. <P>SOLUTION: The device for collecting operation data includes: operation data detection parts 20a, 20b, 20c, 20p, and 20q for detecting operation data associated with the operation of an air conditioner having a refrigeration cycle controlled via communication; a first memory storage 30 for memorizing operation data for each time of a first time interval; an irregularity detection part 40 for detecting irregularity in the operation of the air conditioner; and a second memory storage 50 for memorizing, when the operation irregularity is attributed to a pressure failure with the nonvolatile storage medium adopted, operation data for each time of a second time interval that is more wider than the first time interval, and for memorizing, when the operation irregularity is attributed to a communication failure, operation data for each time of a third time interval that is more wider than the second time interval. <P>COPYRIGHT: (C)2012,JPO&INPIT |
