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.

A vacuum source, comprising:
- a. a first chamber, wherein the first chamber is adaptable between a first chamber state having a first state chamber volume and a second chamber state having a second state chamber volume, wherein the first state chamber volume is greater than the second state chamber volume;
- b. a second chamber, the second chamber containing a refrigerant;
- c. a flexible diaphragm separating the first chamber and the second chamber;
- and
- d. a heating element in the second chamber.
