Total energy recovery devices transfer both temperature and moisture between the airstreams. Two types of these newer technologies are membrane exchangers and liquid desiccant systems. This session covers the science of membrane exchangers and how they transfer water vapor and heat. It also reviews a liquid desiccant system and how this too can be used to transfer water vapor and heat between exhaust and outside airstreams.
