Evaluation of Dehumidifiers with Polymeric Liquid Desiccants. Final Report,October 1991-December 1993

摘要

Candidates for non-corrosive liquid desiccants for air conditioning applicationswere identified through laboratory testing, and the feasibility of a liquid desiccant-enhanced heat-pipe thermal recovery unit for dehumidification was tested. The moisture-sorbing capacity of an organic polymer, triethylene glycol, was found to be increased up to 15% by adding 10% of a soluble solid polymer (polystyrene sulfonic acid sodium or lithium salts). These mixtures, not expected to be corrosive, could lead to a more effective absorber/dehumidifier. The mixtures could remove volatile organic compounds and could be used for improving indoor air quality.
