Multi-stage boiler/regenerator for liquid desiccant dehumidifiers
This patent describes a process for regenerating liquid desiccant used in an air-conditioner. It comprises: providing a first and a second heat exchanger each accommodating a flow of liquid desiccant therethrough for transferring sensible energy, a desiccant regenerator and, a desiccant boiler; removing diluted desiccant from the air conditioner and routing the desiccant through the first heat exchanger so that the temperature of the desiccant is raised, routing the diluted desiccant from the first heat exchanger to the desiccant regenerator wherein the diluted desiccant is partially regenerated, routing the partially regenerated desiccant through the second heat exchanger so that the temperature of the desiccant is raised; routing the partially regenerated desiccant through the desiccant boiler where the desiccant is fully regenerated with moisture from the desiccant being vaporized, routing the regenerated desiccant through the second heat exchanger to lower the temperature of the desiccant, routing the regenerated desiccant through the first heat exchanger to lower the temperature of the desiccant, returning the regenerated desiccant to the air conditioner; and routing the vaporized moisture from the desiccant boiler to the desiccant regenerator to supply energy so that the diluted desiccant is partially regenerated.
