摘要: The present invention relates to a method for detecting and extracting a gaseous fluid contained in a closed loop (10) operating on a Rankine cycle, said loop comprising a multiplicity of constituents with, successively, a circulation and compression pump (12) for a working fluid, a heat exchanger (18) associated with a hot source (24), an expansion machine (30), a cooing exchanger (40), a working fluid tank (46) and circulation pipes (50, 52, 54, 56, 58, 60) connecting these constituents. The invention comprises: —measuring the temperature (Tréelle) and the pressure (Préelle) of the working fluid at a point of the loop when this loop is at rest, and —as soon as the measured pressure (Préelle) exceeds a threshold value (Pliquide saturé) for a given ambient temperature (T), activating an equipment (62) for extracting the gaseous fluid in order to discharge it from the loop.
