METHOD AND SYSTEM FOR PREDICTING RESIDUAL USEFUL LIFE OF AN AIR FILTER

摘要

A method for predicting the residual useful life of an air filter arrangement is described. The method comprises the following steps: providing a plurality of predetermined reference degradation curves (Cj); measuring a degradation parameter (x; Δp) of the filter arrangement (25; 29; 31, 33); estimating the residual useful life (RUL(Ti)) of the filter arrangement (25; 29; 31, 33) by comparing the predetermined reference degradation curves (Cj) and an actual degradation curve (CF) defined by measured values of the degradation parameter.
