Abnormality diagnostic system, air conditioner, and air conditioning system

Abstract

An abnormality diagnostic system includes a processor that acquires operation data of an air conditioner and determines occurrence of abnormality in the air conditioner and occurrence of an abnormality symptom in the air conditioner, a storage that stores abnormality information including a content of the abnormality and information on an occurred time of the abnormality and symptom information including a content of the abnormality symptom and information on an occurred time of the abnormality symptom, and an output interface that outputs the stored abnormality information and the stored symptom information.

What is claimed is: 
     
         1 . An abnormality diagnostic system comprising:
 a processor that:
 acquires operation data of an air conditioner, and 
 determines occurrence of abnormality in the air conditioner and occurrence of an abnormality symptom in the air conditioner; 
   a storage that stores:
 abnormality information including a content of the abnormality and information on an occurred time of the abnormality, and 
 symptom information including a content of the abnormality symptom and information on an occurred time of the abnormality symptom; and 
   an output interface that outputs the stored abnormality information and the stored symptom information.   
     
     
         2 . The abnormality diagnostic system according to  claim 1 , wherein the information on the occurred time of the abnormality and the information on the occurred time of the abnormality symptom each include an electrification time of the air conditioner. 
     
     
         3 . The abnormality diagnostic system according to  claim 1 , wherein the information on the occurred time of the abnormality and the information on the occurred time of the abnormality symptom each include an operation time of the air conditioner. 
     
     
         4 . The abnormality diagnostic system according to  claim 1 , wherein
 the storage further stores:
 restart information including a content of a restart of the air conditioner to be executed before definition of the abnormality, and 
 information on an occurred time of the restart, and 
   the output interface further outputs the stored restart information.   
     
     
         5 . The abnormality diagnostic system according to  claim 1 , wherein the processor causes a display of the air conditioner to notify a user of the content of the abnormality upon occurrence of the abnormality but not notify the user of the content of the abnormality symptom upon occurrence of the abnormality symptom. 
     
     
         6 . An air conditioner comprising the abnormality diagnostic system according to  claim 1 . 
     
     
         7 . An air conditioning system comprising:
 an air conditioner; and   a management device connected with the air conditioner via a local communication network and including the abnormality diagnostic system according to  claim 1 .   
     
     
         8 . An air conditioning system comprising:
 an air conditioner;   a first management device connected to the air conditioner via a local communication network; and   a second management device connected to the first management device via a wide area communication network, wherein   either the air conditioner or the first management device includes the abnormality diagnostic system according to  claim 1 , and   the abnormality diagnostic system further comprises a transmitter that transmits the abnormality information and the symptom information to the second management device.   
     
     
         9 . An air conditioning system comprising:
 an air conditioner; and   a management device connected to the air conditioner via a wide area communication network and including the abnormality diagnostic system according to  claim 1 , wherein   the abnormality diagnostic system further comprises a transmitter transmits either the abnormality information or the symptom information via the wide area communication network.
