JULY 20, 1998

What is relative humidity? Absolute humidity? How is humidity controlled in buildings? What do different specifications imply for a HVAC (Heating, Ventilating and Air Conditioning) system designer and for a building's HVAC operations and maintenance staff?  What measurement technologies are practical and affordable?  Lew Harriman, a consultant in humidity control technology, will review the fundamental principles of humidity control technology and humidity control.  He will explain the basic operating principles of mechanical systems and how they achieve and maintain humidity control.  Author and illustrator of The Dehumidification Handbook and the Commercial Desiccant System Handbook, Mr. Harriman is an active member of ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers).   He is responsible for the current revision of Chapter 21 of the ASHRAE Handbook of Fundamentals.  This course will include a tour of a Paul E. Garber facility building and the dehumidification systems installed in a storage area there.  The text for the course will be The Dehumidification Handbook, 2nd edition.

Who Should Attend:  This one day course is designed for conservators and collection managers with some reading knowledge of the literature on environmental conditions, but with an interest in reviewing the fundamental principles of humidity control, and its engineering terminology.  This course may also be helpful to conservation scientists, appraisers, and insurance adjusters.
