Publication number: 20240151230Abstract: A computer-implemented method for detecting condensate in an oil system of a compressor, having an inlet and an outlet. The method incudes the steps of: determining the humidity at the inlet and at the outlet or downstream of the outlet of the compressor; determining the amount of water vapor that enters and exits the compressor based on the humidity determined at the inlet and the outlet or downstream of the outlet; determining the amount of condensate that remains in the compressor by determining the difference between the amount of condensate that enters and exits the compressor; storing the amount of condensate that remains; and repeating the aforementioned steps at regular intervals and storing the amount of condensate and how long said condensate remains in the compressor.Type: ApplicationFiled: March 1, 2022Publication date: May 9, 2024Applicant: ATLAS COPCO AIRPOWER, NAAMLOZE VENNOOTSCHAPInventor: Jeroen Alois M.
