In all-air systems, central fans circulate conditioned air to and from the spaces through long runs of ductwork

In air and water systems, air is ducted to each space. Heated water and chilled water are also piped to each space, where they are used to modify the temperature of the circulated air at each outlet to meet local demands.

In all water systems, air is circulated locally rather than from a central source, so ductwork is eliminated.
