A method for regulating the volume flow of a wetting fluid during adiabatic cooling, wherein an evaporating surface (11) is wetted with the wetting fluid flowing along the evaporating surface (11), so that the to-be-cooled and / or the air to be humidified flows over the evaporating surface (11) substantially transversely to the direction of flow (15) of the wetting liquid. The solution for regulating the efficiency of the volumetric flow of wetting fluid. The solution of the present invention to achieve the above object is: after wetting the evaporating surface (11) for a certain duration, reduce the volume flow of the wetting liquid flowing through the evaporating surface (11), after reducing the volume After flow, the temperature (T1, T2) and / or time-dependent temperature gradients (ΔT1, ΔT2) are determined, wherein the volumetric flow rate of the wetting fluid is adjusted according to the determined temperatures (T1, T2) and / or time-dependent temperature gradients (ΔT1, ΔT2) .
Description
technical field [0001] The invention relates to a method for regulating the volume flow of wetting fluid during adiabatic cooling, wherein the evaporating surface is wetted with a wetting fluid flowing along the evaporating surface so that the cooling and / or wetting Air flows across the evaporating surface generally transverse to the direction of flow of the wetting liquid. [0002] The invention also relates to a device for regulating the volume flow of wetting fluid during adiabatic cooling, the device having an evaporation surface which can be wetted by the wetting fluid provided by a wetting device and which can be Heat is exchanged with the air to be cooled and / or moistened during the adiabatic cooling and / or moisturizing process, wherein the moisturizing surface flowing along the evaporative surface during the cooling and / or moisturizing process The volume flow of the wetting liquid can be adjusted, the air to be cooled and / or humidified flows substantially transversely...
