Abstract
Integrated systems comprising both i) heat and mass exchange systems and ii) electrolysis stacks are disclosed, together with related methods of use. The disclosed systems cool and/or dehumidify air using two streams of salt solutions as liquid desiccants.
Claims20
A system, comprising:
- a heat and mass exchanger;
- at least one electrodialysis stack;
- a high salt ion concentration liquid desiccant;
- and
- a low salt ion concentration liquid desiccant;
- wherein:
- the high salt ion concentration liquid desiccant and the low salt ion concentration liquid desiccant are in a single, continuous stream that connects the heat and mass exchanger and the at least one electrodialysis stack;
- the high salt ion concentration liquid desiccant absorbs water from a process air stream in the heat and mass exchanger and rejects salt ions to the low salt ion concentration liquid desiccant in the at least one electrodialysis stack;
- and
- the low salt ion concentration liquid desiccant desorbs water from a purge air stream in the heat and mass exchanger and accepts ions from the high salt ion concentration liquid desiccant in the at least one electrodialysis stack.

A method of dehumidifying air, comprising:
- absorbing water from a process air stream into a high salt ion concentration liquid desiccant in a heat and mass exchanger, dehumidifying the process air stream;
- desorbing water from a low salt ion concentration liquid desiccant into a purge air stream in the heat and mass exchanger;
- moving the high salt ion concentration liquid desiccant and the low salt ion concentration liquid desiccant to at least one electrodialysis stack;
- rejecting salt ions from the high salt ion concentration liquid desiccant to the low salt ion concentration liquid desiccant in the at least one electrodialysis stack, converting the high salt ion concentration liquid desiccant into the low salt ion concentration liquid desiccant;
- and
- accepting ions from the high salt ion concentration liquid desiccant into the low salt ion concentration liquid desiccant in the at least one electrodialysis stack, converting the low salt ion concentration liquid desiccant into the high salt ion concentration liquid desiccant;
- wherein:
- the high salt ion concentration liquid desiccant and the low salt ion concentration liquid desiccant flow in a single, continuous stream that connects the heat and mass exchanger and the at least one electrodialysis stack;
- and
- the converted high salt ion concentration liquid desiccant and the converted low salt ion concentration liquid desiccant are moved to the mass and heat exchanger.
