Abstract (en)
[origin: WO2017089588A1] The invention relates to a method for drying a chamber, including the steps of: connecting the chamber to air extraction and inlet means and to a member for measuring air pressure in the chamber, controlling said means for extracting air from the chamber until a first pressure is reached, controlling said means for initiating repetition of cycles of increasing pressure up to a second pressure and of reducing pressure down to near the first pressure, the first pressure and the second pressure being within a water evaporation range, interrupting the repetition and controlling said means for extracting air from the chamber until a third pressure near the triple point of water is reached, and restoring the chamber to ambient temperature and disconnecting said air extraction and inlet means.
