Designing an air handling system can be a challenging task given the vast arrary of systems options from which to choose. In this highly practical reference, HVAC engineers will find all the information and guidance they need to select the most cost-effective, energy-efficient system to satisfy the design requirements of a specific project. The only book available that focuses exclusively on central air handling systems, this comprehensive book explores the full range of designs for systems commonly in use today in all types of buildings. The author provides detailed information on more than 25 constant volumes, variable volume, and hybrid systems - including single zone, terminal reheat, double duct, dual conduit, and hydronic heat pump systems. In addition, the book fully examines the differences between various system types, evaluates the advantages and disadvantages of each system, reviews basic heating and cooling loads and load variations, discusses the importance of psychrometrics in system design and selection, and outlines techniques for energy conservation and system retrofitting. Of special interest are the many diagrams that clearly illustrate all types of air handling system designs.
