COMBINED HEAT SOURCE AND VACUUM SOURCE FOR LOW-COST DISTILLATION AND DESALINATION

摘要

A distillation and desalination system can include a refrigeration unit and a vacuum source positioned in the refrigeration unit. The vacuum source can include a first chamber defining a first chamber volume, a second chamber defining a second chamber volume, a flexible diaphragm dividing the first chamber and the second chamber; and a check valve permitting gas transport into and out of the first chamber, the check valve comprising an inlet and an outlet. The system can also include a distillation unit having a distillation chamber, a saline liquid in the distillation chamber, and a headspace above the saline liquid, the headspace comprising a gas. The inlet of the check valve can be fluidically coupled to the headspace of the distillation unit.
