In cooling equipment, air is caused to pass through a wet cooling tower section (W) and thus precooled a prior to passage across the tube bundle (16) of a dry cooling tower section (D) through which a medium to be cooled is circulated, and then either selectively vented or recirculated successively through the wet section and across the tube bundle according to the positions of adjustable louvres (26, 27, 28, 29). <IMAGE> |
