Abstract (en)
[origin: EP1249263A2] Method for operating a cleaning system used for cleaning workpieces in a closable work room (4) using solvents comprises removing air from the work room, an air- or water-cooled condenser (8) and a line system (9, 12) connecting the work room and the condenser on the application of a very low negative pressure after closing the work room, cleaning the workpiece in the work room using a solvent whose saturated steam is fed to the work room by a steam generator (1), producing a first connection (14) between the work room and the condenser until the pressure has equalized between the two, interrupting the first connection and producing a second connection (16) between the work room and the condenser so that steam is sucked from the work room and compressed to a pressure at which its temperature lies above the cooling temperature of the air- or water-cooled condenser, feeding the solvent condensate formed in the condenser to the reservoir container (28), and ventilating t he work room after reaching a specified negative pressure in the work room and opening the work room. Preferred Features: After the removal of air the first and second connection are closed and remain closed during cleaning of the workpiece.
