CLOSED CIRCUIT TYPE PLUME ABATEMENT COUNTERFLOW COOLING TOWER AND FREE COOLING SYSTEM USING THE SAME

摘要

The present invention relates to a closed type white smoke reducing counterflow cooling tower and an outdoor air cooling system using the same. More specifically, the closed type white smoke reducing counterflow cooling tower and an outdoor air cooling system using the same can efficiently product cool water and save operating and maintenance costs. The closed type white smoke reducing counterflow cooling tower and an outdoor air cooling system using the same comprise: a second dry heat exchange unit disposed in an exhaust area (6) to carry out dry cooling and reduce white smoke; a bypass exhaust opening and closing unit provided between a first dry heat exchange unit and the second dry heat exchange unit; a cooling high temperature fluid opening and closing control valve (111) provided in a high temperature fluid supply pipe (131a); a cooling high temperature fluid opening and closing control valve (112) provided in a cooling high temperature fluid discharge pipe (132a); and a control unit (200).
