Abstract

A maintenance-information providing system is configured to provide information to maintain an air conditioner more appropriately. The system has an actual trouble code data storage section which stores data based on a trouble code, an actual predictive trouble code data storage section which stores data based on a predictive trouble code, a code-correspondence data storage section which stores a trouble code corresponding to a predictive trouble code and a maintenance-portion-information outputting section. The maintenance-portion-information outputting section extracts a trouble portion of the air conditioner corresponding to the predictive trouble code based on the data of the actual trouble code data storage section and the actual predictive trouble code data storage section. At the same time, the trouble code corresponding to the predictive trouble code is extracted and then a trouble portion of the air conditioner corresponding to the trouble code is extracted.

Claims9

Dependent claims

A maintenance-information providing system for providing maintenance information of an apparatus, comprising:

a storage unit configured to store storage data including trouble data of the apparatus and predictive trouble data of the apparatus, the storage unit including
an actual trouble data storage section configured to store correspondence between the trouble data and the trouble portion in the apparatus that has previously occurred,
an actual predictive trouble data storage section configured to store correspondence between the predictive trouble data and the trouble portion in the apparatus that has previously occurred, and
a corresponding data storage section configured to store the trouble data corresponding to the predictive trouble data;
and
a processing unit configured to extract a trouble portion of the apparatus corresponding to the predictive trouble data, based on the storage data of the storage unit, and to extract the trouble data corresponding to the predictive trouble data from the corresponding data storage section and then extracts the trouble portion of the apparatus corresponding to the trouble data.
