Track: Fundamentals and Applications
Sponsor: 8.12 Desiccant Dehumidification Equipment and Components, 5.5 Air-to-Air Energy Recovery
Chair: Mark Piegay, Associate Member, Alfa Laval - Kathabar, Tonawanda, NY
Studies indicate that over 40% of energy consumption in a hospital is due to reheating of supply air that has been over cooled in order to satisfy prescribed humidity requirements and minimum air change rates. This session explains the basics of solid rotor desiccant systems and liquid desiccant systems and how they can be used to reduce the amount of cooling and subsequent reheating required to maintain environmental conditions in hospital operating rooms. Benefits to infrastructure required to support the operating room HVAC system are discussed.

2. Applying Liquid Desiccant Systems in Temperature and Humidity Control for Hospital Operating Rooms
Mark Piegay, Associate Member, Alfa Laval - Kathabar, Tonawanda, NYThis session explains the basics of liquid desiccant systems and how they can be applied to surgical suites HVAC designs to save energy compared to conventional methods of over cooling and reheat. Benefits of the system include maintaining tight control of the required temperature and humidity specified by ASHRAE Standard 170 for surgical suite designs as well as cleaning the air of bacteria and viruses.
