The car (1) has a water chamber (8) comprising an outer face (10), an inner face (11), an air inlet opening (12), an air outlet opening (13) and a water outlet opening (14). The inner face forms a water separating chamber (16) that is connected to the air inlet and outlet openings and the water outlet opening. The water outlet opening discharges water out of the separating chamber. An air conditioner (22) is connected to the air outlet opening to feed air from the water chamber into the air conditioner. An air feeding unit (33) sucks the air into the air conditioner via the air inlet opening. The air feeding unit is designed as a suction fan. The water chamber comprises a wall that comprises fibers forming a non-woven fabric i.e. felt.
