Leonardo da Vinci apparently designed cooling system for buildings. In fact it started with a noblewoman Isabella d’Este, whose home was in Mantua, Italy, where Leonardo da Vinci was a guest in 1500. The cool air, was created by a paddlewheel in an enclosed water-filled chamber, which was blown into the room by a bellows.
