Cooling tower,Iran. These tower structures have been used in Iran 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 in the top of the tower (upper right) | |
