HVAC Control System Design Diagrams - John Levenhagen (McGraw-Hill, 1999).pdf

No more useful reference for the designer or specifier of HVAC control systems exists than this complete "cookbook" of generic segments and sequences. This indispensable professional compendium gives you a broad array of diagrams that provides everything you need to design controls for an in-place or in-plan HVAC system; offers ready-to-go details for retrofitting, updating, or designing controls for altered systems; allows clear comparisons among commercial control systems; shows you frequently-made and useful modifications to controls; demonstrates how to create controls for peak efficiency, air quality, and energy conservation; covers air handling, terminal, and primary systems; offers sequences and segments for virtually any HVAC system need; and shows you how standard control algorithms work in particular systems. These highly useful control diagrams, many of them comparable to commercially available models, let you design or specify needed configurations in the most efficient manner possible. Written by a vastly experienced HVAC control engineer, in full compliance with ASHRAE standards, and covering both hardware and software applications, this unique volume fills a definite need. It fully deserves a place of honor within easy reach of every HVAC engineer's design desk.
