The system controls the proportion of air to avoid fog-generation. ) e temperature and relative humidity of the ambient air are measured, as are the exhaust air temperatures from the wet (KN) and dry (KT) sections, and are used as parameters of the actual operating conditions, and determine the air flow proportions through the two sections. The flow through the dry section is regulated, while that through the wet section is maintained to give the necessary cooling effect. Where a common flow system is used, by natural draught or forced draught with fan (2), flow can be regulated by varying the free cross-sectional area. |
