Cooling columns contain wet deck surfaces. The cooling capacity of a cooling column is determined by the surface of these wet deck surfaces.
WL 320.01 contains a small wet deck surface. The cooling column type 2 is placed into WL 320 instead of the column type 1. The cooling capacity of both columns is compared.
On top of the cooling column, a nozzle is mounted. The hot water is sprayed at the top of the cooling tower, trickles from the top to the bottom along the wet deck surface and is cooled in the process. The air enters the column from the bottom and flows upwards.
The cooling column is fitted with connections for differential pressure measurement at its inlet and outlet.
