Abstract

An ionic liquid desiccant system utilizes an ionic liquid desiccant to draw moisture from a working fluid, such as air that flow into an enclosure, such as a home. The desiccant may be mixed with the working fluid or a separator that allows moisture transport therethrough may be configured between the ionic liquid desiccant and the working fluid. The ionic liquid desiccant system may be part of an air conditioning system and may remove the moisture from air that is cooled by flowing over an evaporator or heat exchanger coupled with the evaporator. The ionic liquid desiccant may be pumped from a desiccant chamber to a regenerator chamber to remove absorbed moisture. A dual-purpose chamber may act as a desiccant chamber and as a regenerator chamber. A refrigeration system may have an electrochemical compressor and may utilize metal hydride heat exchangers.
