Staying Dry & Comfortable With Liquid Desiccants

Let a scientist with experience both at the National Renewable Energy Laboratory and on the manufacturer side discuss the possibilities of a newer dehumidification technology within the framework of the same old moisture challenges.
June 1, 2013
In the summer, conventional air-conditioning systems in buildings are challenged to meet peak humidity loads. Over time, buildings have reduced their heat (sensible) load, but have done less to reduce their moisture (latent) load. As a result, this moisture load can become too large for conventional air-conditioning systems to handle.
