Energy saving device for evaporative condenser

The utility model relates to an energy saving device for an evaporative condenser and belongs to the energy saving technical field of a condenser. The technical scheme of the energy saving device for the evaporative condenser is that a control panel cabinet is respectively connected with output signals of a gas temperature detecting unit (10), a water collecting basin water temperature detecting unit (13), a temperature detecting unit (11) for a cooled medium inlet and a temperature detecting unit (12) for a cooled medium outlet; a frequency controlling unit (15) of an axial flow fan and a frequency controlling unit of a circulating water pump are also connected with the control panel cabinet; output of the frequency controlling unit of the axial flow fan is connected with the axial flow fan; and the output of the frequency controlling unit of the circulating water pump is connected with the circulating water pump. The energy saving device for evaporative condenser optimizes an operation load of the axial flo
