  • Key performance index calculation and real-time condition monitoring methods for heat exchanger
    Publication number: 20060144057
    Abstract: A method for calculating key performance indexes. The method comprising defining running indexes for a heat exchanger of a chiller, obtaining an outlet temperature of output matter of the heat exchanger according to the running indexes, at least comprising load temperature, load current, inlet temperature of cooling matter, outlet temperature of the cooling matter, and inlet temperature of the output matter, obtaining a performance index according to the inlet and outlet temperatures of the output matter and the load current of the heat exchanger, obtaining a predicted performance index according to the inlet temperature of the output matter, a predicted outlet temperature of the output matter, and the load current, obtaining a real performance index according to the inlet temperature of the output matter, real outlet temperature of output matter, and the load current, and obtaining a key performance index according to the predicted and real performance indexes.
