Desiccant brine (12) is heated and diluted in an air drier (17) by coming into contact with air to be cooled in an evaporative cooler (23), but is regenerated by dewatering in a vacuum chamber (11), from which it is discharged first into a sump (16), and then back into the vacuum chamber (11). Both the desiccant brine (12) and air are heated in the air drier (17), and the hot brine when in the vacuum chamber (11) has a temperature above atmospheric, which provides a higher vapour pressure and its water is readily vaporised. The higher efficiency reduces the amount of heat input required, and thereby reduces the extent of heat exchanger requirement. |
