Abstract
Disclosed herein are systems and processes to thermally regenerate and re-concentrate a liquid desiccant (absorbent) with an electrically driven heat pump. The regeneration and re-concentration may be performed in a cost and energy efficient manner.
Claims17
A method comprising:
- removing a moisture from a first air stream using a desiccant to absorb the moisture;
- operating a heat pump comprising a refrigerant stream circulating through an evaporator, a compressor, a valve, and a condenser;
- routing the desiccant that is diluted with the moisture through the condenser to heat the desiccant and evaporate the moisture;
- collecting the evaporated moisture using a second air stream also routed through the condenser;
- and
- depositing the evaporated moisture in the evaporator by routing the second air stream through the evaporator.
