Full Description

This chapter provides basic information for evaluating windflow patterns, estimating wind pressures, and identifying problems caused by the effects of wind on intakes, exhausts, and equipment. In most cases, detailed solutions are addressed in other chapters. Related information can be found in Chapters 11, 14, 16, and 36 of this volume; in Chapters 31, 32, 45, 47, and 53 of the 2011 ASHRAE Handbook—HVAC Applications; and in Chapters 30, 35, and 40 of the 2012 ASHRAE Handbook—HVAC Systems and Equipment. This chapter mainly covers equipment and systems that dehumidify air rather than those that dry other gases or liquids. Both liquid and solid desiccants are used; they either adsorb water on the desiccant’s surface (adsorption) or chemically combine with water(absorption).
