Patent ID: 8165829

Claim:
An aggregating system for system diagnosis, comprising: inputting means for receiving from a trap diagnotor a result of a trap operation diagnosis performed by the trap diagnotor for diagnosing operational conditions of a plurality of evaluation target steam traps in a client's evaluation target system and receiving from a leakage diagnotor result of a fluid leakage diagnosis performed by the leakage diagnotor for diagnosing leakage of fluid from respective portions of an evaluation target piping in the evaluation target system; and calculating means for calculating, based on the result of the trap operation diagnosis inputted to the inputting means, a total trap-passed steam loss amount obtained by aggregating trap-passed steam loss amounts for all the evaluation target steam traps and calculating, based on the result of the fluid leakage diagnosis inputted to the inputting means, a total fluid leakage loss amount obtained by aggregating fluid leakage loss amounts from the respective portions of the piping for each type of fluid; and said calculating means also calculating a sum total steam loss amount obtained by adding together a total fluid leakage loss amount for steam included in the total fluid leakage loss amount for each fluid type and the total trap-passed steam loss amount, and calculating, based on the sum total steam loss amount and a total unknown steam amount inputted to the inputting means, a ratio of the sum total steam loss amount relative to the total unknown steam amount, which is a difference between a total receiving steam amount and a total necessary steam amount inputted to the inputting means, as an improvable unknown steam ratio, wherein the total unknown steam amount is calculated or acquired prior to being inputted to the inputting means.
