Remote monitoring system for air conditioners

A remote monitoring system for air conditioners used by at least one user and installed respectively in a plurality of buildings for concentrically monitoring the operating state of the air conditioners from a distance, the system comprising data collectors installed in the respective buildings, and a remote monitor connected to the data collectors of all the buildings via a communication network, each of the data collectors comprising:

• data collecting means for collecting state data representing the operating state of the air conditioner installed in each building,
• transmitting means for transmitting the collected state data to the remote monitor,
• receiving means for receiving the parameters transmitted to the data collector,
• adjusting means for setting the received control parameters in the air conditioner and thereby adjusting the operating state thereof, and
• adjuster notification means,
• the remote monitor comprising:
• receiving means for receiving the state data collected by each data collector,
• diagnosing means for diagnosing the operating state of the air conditioner installed in each building based on the received state data, and
• output means for outputting the result of diagnosis of the air conditioner, and
• remote monitor notification means,
• wherein the diagnosing means of the remote monitor prepares a candidate value or candidate values for one or a plurality of control parameters required for improving the operating state based on the result of diagnosis of the air conditioner, and the output means outputs the candidate value or values prepared as the result of diagnosis and wherein the adjusting means sets the received control parameters in the air conditioner for adjusting the operating state thereof such that, if the result of the diagnosis of the air conditioner in each building indicates a need for operational adjustment, the remote monitor notification means notifies the adjusting means of the need for operation adjustment and, after the adjusting means is notified of the need for operational adjustment by the remote monitor notification means, the adjuster notification means notifies the at least one user that operation adjustment is to be made and, upon receipt of permission by the at least one user, the adjusting means adjusts the operating state.
