Abstract:
The equipment space (10) is a closed space provided with electrical equipment (40, 50) and an air dryer (30) condensing the moisture of the air in the equipment space (10) into water. The arrangement for removing water from the equipment space comprises a porous element (60) having a capillary structure and being situated in an outlet opening (70) of said equipment space (10). Water condensed by the air dryer (30) is directed to a first inner surface of the porous element (60), said water propagating in the capillary structure of the porous element (60) from the first inner surface of the porous element (60) to a second outer surface of the porous element (60) from which second outer surface of the porous element (60) the water is released to the ambient air outside the equipment space (10).
