Ventilation seat

A vehicle seat having a ventilation system includes a network of ducts within the seat bottom, and a fan for moving air away from the seat surface. The ventilation system is configured such that a single fan may selectively move air through some or all of the ducts. Before a vehicle occupant sits in a seat, air is moved through all of the ducts to reduce the temperature at the seat surface. When the occupant sits in the seat, certain ducts in the network are closed to air flow. The air flow is now limited to the remaining ducts, which allows for efficient removal of moisture from the seat surface. After the temperature and moisture at the seat surface have reached desired levels, the speed of the fan is reduced to ensure that the occupant does not experience an unpleasant draught.
