The building industry accounts for about 25 percent of the US gross national product through the design, construction, operation, and maintenance of commercial, institutional, and residential buildings. The Handbook of Heating, Ventilation, and Air Conditioning provides a current, comprehensive review of the latest procedures and trends in the industry. It combines practice and theory, systems and control, and modern methods and technologies to provide, in one volume, all of the design and operation information needed by HVAC engineers. Through a link on the CRC Web site, owners of the handbook can access new material periodically posted by the author.
