Method and device for regulating a volume flow of a wetting fluid during adiabatic cooling

Abstract

In a method for controlling a volume flow of a wetting fluid during adiabatic cooling, an evaporation surface (11) being wetted with the wetting fluid which flows along the evaporation surface (11) and the air to be cooled and / or to be wetted being directed substantially transversely relative to the flow direction (15) of the wetting fluid over the evaporation surface (11), a solution is intended to be provided by means of which the efficiency of the control of a volume flow of a wetting fluid during adiabatic cooling can be increased with simple means. This is achieved in that the volume flow of the wetting fluid flowing over the evaporation surface (11) is reduced after a predetermined period of wetting of the evaporation surface (11) and, after the volume flow is reduced, temperatures (T1, T2) and / or time / temperature gradients ([Delta]T1, [Delta]T2) of the air directed past the evaporation surface (11) are established at least at two different positions in the flow direction (15) of the wetting fluid substantially parallel with the evaporation surface (11), with the volume flow of the wetting fluid being controlled in accordance with the established temperatures (T1, T2) and / or time / temperature gradients ([Delta]T1, [Delta]T2).

Description

technical field [0001] The invention relates to a method for regulating the volume flow of a wetting liquid during adiabatic cooling, wherein the evaporating surface is wetted with a wetting liquid flowing along the evaporating surface, so that the Air flows over the evaporation 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 a wetting fluid during adiabatic cooling, said device having an evaporating surface which can be wetted by a wetting fluid supplied by a wetting device and which can Exchange heat with the air to be cooled and / or humidified during the adiabatic cooling and / or wetting process, wherein the humidified air flowing along the evaporating surface during the cooling and / or wetting process The volume flow of the wetting liquid can be adjusted, the air to be cooled and / or humidified flowing substantially transversely to the direction of flow of the wettin...

AI Technical Summary

Problems solved by technology

Existing systems for cooling the air, such as contact humidifiers or air scrubbers, have the disadvantage that it is difficult or even impossible to regulate the water used to carry out the relevant process, and the inlet water can only be set at a fixed volume flow by means of a valve control on or off completely
