Seminar 54 -- From Research to Reality: Advances in Liquid Desiccant Technology

This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted.

Over the last two decades significant advances have been made in the use of liquid desiccants for simultaneous dehumidification and cooling. Modelling by National Renewable Energy Laboratory (NREL) and earlier proof of concept demonstrations have shown potential savings of 30-40% compared to other technologies. In recent years, results of several proofs of concept laboratory and field tests have been reported. Currently, prototypes for Dedicated Outside Air Systems (DOAS) have been tested for performance and reliability, using the AHRI 920 standard. The results of these tests are reported.
