KONDENSATIONSVERFAHREN FUER UNTER UNTERDRUCK STEHENDEN WASSERDAMPF.

摘要

The water vapour, extracted from a drier, is condensed by vacuum, generated by a fluid-ring air pump, with the pump fluid condensing the vapours. Water is used as the fluid in the air pump (3), and is passed through a heat-exchanger (6) for heat extraction. Before entering the air pump it passes through another heat exchanger (4), transferring waste heat from the latter and from the pump drive motor. A heat-insulating housing (10,11) round the air pump, its motor (33) and the second heat exchanger (4) prevents heat losses.
