Cooling tower. Interior view looking up inside a cooling tower in Iran. These tower structures have been used here since ancient times to keep food and other items cool. Ice is brought here from the mountains in winter and stored in the towers through the summer. The tall,bell-shaped towers are up to 20 metres in height. The cooling effect is caused by a downdraft of air from the narrow opening (upper left) in the top of the tower | |
