Liquid desiccant air conditioning using air as heat transfer medium

A liquid desiccant system includes a liquid desiccant loop having an absorber unit in fluid communication with a desorber unit and liquid desiccant flowing between the absorber unit and the desorber unit. The liquid desiccant system includes a supply airflow path passing through the absorber unit and forming an absorber liquid/air interface within the absorber unit and a conditioned airflow exiting the absorber unit. The liquid desiccant system includes a regeneration airflow path passing through the desorber unit and forming a desorber liquid/air interface within the desorber unit and an exhaust airflow exiting the desorber unit. A heat exchanger is thermally coupled to the supply airflow path for removing heat from supply airflow upstream of the absorber unit. A heat exchanger is thermally coupled to the regeneration airflow path adding heat to regeneration airflow upstream of the desorber unit.

Claims preview

1 . A liquid desiccant system comprising: a liquid desiccant loop in fluid communication with an absorber unit and a desorber unit such that liquid desiccant is flowable between the absorber unit and the desorber unit; a supply airflow path passing supply airflow at a supply temperature and an absolute humidity through the absorber unit and forming an absorber liquid/air interface within the absorber unit and a conditioned airflow path exiting the absorber unit; a regeneration airflow path passing regeneration airflow at the supply temperature and the absolute humidity through the desorber unit and forming a desorber liquid/air interface within the desorber unit and an exhaust airflow path exiting the desorber unit; and a heat exchanger thermally coupled to the supply airflow path and configured to remove heat from the supply airflow upstream of the absorber unit, the heat exchanger thermally coupled to the regeneration airflow path and configured to add heat to the regeneration airflow upstream of the desorber unit, wherein the liquid desiccant loop between the absorber unit and the desorber unit is a closed loop that does not include a desiccant-to-liquid heat exchanger and does not include a desiccant-to-refrigerant heat exchanger. 2 . The liquid desiccant system of claim 1 , wherein at least 95% of total heat added to the liquid desiccant is added at the desorber liquid/air interface within the desorber unit. 3 . The liquid desiccant system of claim 1 , wherein the liquid desiccant has a first temperature exiting the absorber unit and a second temperature entering the desorber unit and the first temperature and second temperature are substantially equal.
