Märksõnad:
Engineers McDowell and Montgomery prepared the 2009 edition, which was a revision of an earlier edition by Steven T. Taylor in 1998. It can serve as a reference on systems for moving air around inside a building, for owners and operators, mechanical engineers and contractors, and facility engineers. It can also be used with the online course of the same title. The topics include basics of electricity, sensor and auxiliary devices, pneumatic controls, control diagrams and sequences, and digital controls specification.
