What is claimed is:
1. A water production unit comprising: a liquid loop having a liquid desiccant, the liquid loop adapted to be exposed to a process air for adsorbing moisture with the liquid desiccant; an exhaust source producing heat; a heat exchanger in fluid communication with the exhaust source, the heat exchanger arranged to provide the heat to the liquid loop for desorbing moisture from the liquid desiccant and producing steam; a storage container in fluid communication with the liquid loop for collecting the moisture; and wherein the liquid loop intersects a duct carrying the process air, the liquid loop exposing the liquid desiccant to the process air, a condenser arranged in the duct configured to receive the steam and produce condensate, the condensate returned to the storage container.
2. The water production unit according to claim 1, wherein the liquid loop includes a tank fluidly connected to the storage container.
3. The water production unit according to claim 2, wherein the heat exchanger is in fluid communication with the tank.
4. The water production unit according to claim 3, wherein the condenser is arranged between and in fluid communication with the storage container and the tank, the condenser receiving the steam from the tank and producing the condensate collected by the storage container.
5. The water production unit according to claim 1, wherein the liquid loop includes a contactor dispersing the liquid desiccant in the process air to adsorb moisture, and a collector gathering moisture-laden liquid desiccant into the liquid loop.
6. The water production unit according to claim 5, wherein the liquid loop includes a desiccant cooler arranged in the process air upstream of the contactor.
7. The water production unit according to claim 5, wherein a regeneration heat exchanger is in fluid communication with the liquid loop, the regeneration heat exchanger assisting the heat exchanger in desorbing moisture from the liquid desiccant.
8. The water production unit according to claim 1, wherein a fan is arranged within the duct for moving the process air through the duct.
9. The water production unit according to claim 1, wherein the exhaust source is a combustion engine of a mobile vehicle. |
