Abstract

A dry cooling tower (1) having an axis of symmetry (6) employs a hybrid process for condensing a gaseous cooling medium e.g. ammonia assisted by a forced air circulation (4B) via a variable speed electric fan (14,16) mounted in the head (13) of the tower. A two-stage heat exchanger (2) comprises the upper and lower baffle matrices (3,4) through which a single continuous conduit provides a labyrinth path for the gas being condensed from its inlet (15) to its outlet (23). Forced air cooling commences at the upper stage (3) and final cooling is effected by a pumped (19) cold-water circulation through the lower stage (4) of the heat exchanger whilst the airflow is maintained.
