Abstract
A distillation and desalination system can include a refrigeration unit, a distillation unit, and a vacuum source positioned in the refrigeration unit. The distillation unit may include a distillation chamber containing a saline liquid and a headspace above the saline liquid, the headspace comprising a gas. The vacuum source may include a first chamber defining a first chamber volume, where gas transport is permitted into and out of the first chamber and the first chamber is fluidically coupled to the headspace of the distillation unit, and a second chamber defining a second chamber volume, wherein the first chamber and the second chamber are fluidically isolated.
