Warm Air Heating describes the underlying principles of heating by warm air and illustrates how these are carried into practice. This book discusses the heat transmission through building construction, warm air heating classifications, computation of heat requirements, and fan laws and definitions. The air filter performance determinants, reactivation heat requirement versus adsorption capacity of sorbsil silica gel, and erection of ductwork are also elaborated. This text likewise covers the field measurement of sound, theory of vibration isolation, application of thermal insulation, and behavior of a heated air jet. Other topics include the duct layouts, electrically operated controls, measurement of air flow, and warm air heating using high temperature heating media. The off-peak electric warm air heaters and industrial applications of warm air heating are also deliberated. This publication is recommended for students, designers, and installers of warm air heating systems.
