Sorption refers to the binding of one substance to another. Sorbents are materials that have an ability to attract and hold other gases or liquids. They can be used to attract gases or liquids other than water vapor, which makes them very useful in chemical separation processes. Desiccants are a subset of sorbents; they have a particular affinity for water. This chapter discusses the water sorption characteristics of desiccant materials and explains some of the implications of those characteristics in ambient-pressure air-conditioning applications. Information on other applications for desiccants can be found in Chapter 36 of this volume; Chapters 7, 8, 18, 39, and 44 of the 2014 ASHRAE Handbook–Refrigeration; Chapters 1, 2, 6, 10, 18, 20, 23, 30, and 46 of the 2015 ASHRAE Handbook–HVAC Applications; and Chapters 24 and 26 of the 2016 ASHRAE Handbook–HVAC Systems and Equipment.
