Abstract
An air treatment system includes a three-way heat exchanger, a heat transfer fluid loop, and a pre-treatment heat exchanger positioned on the heat transfer fluid loop. The three-way heat exchanger is operable to transfer heat and moisture between air, a liquid desiccant, and a heat transfer fluid. The heat transfer fluid loop circulates the heat transfer fluid between the three-way heat exchanger and a second heat exchanger operable to transfer heat between the heat transfer fluid and a third working fluid. The pre-treatment heat exchanger is positioned on the heat transfer fluid loop between the second heat exchanger and the three-way heat exchanger and is operable to transfer heat between the air and the heat transfer fluid upstream from the three-way heat exchanger.
