PCT No. PCT/AU95/00314 Sec. 371 Date Nov. 27, 1996 Sec. 102(e) Date Nov. 27, 1996 PCT Filed May 29, 1995 PCT Pub. No. WO95/33161 PCT Pub. Date Dec. 7, 1995Desiccant brine is heated and diluted in an air drier by coming into contact with air to be cooled in an evaporative cooler but is regenerated by dewatering in a vacuum chamber, from which it is discharged first into a sump, and then back into the vacuum chamber. Both the desiccant brine and air are heated in the air drier and the hot brine when in the vacuum chamber has a temperature above atmospheric, which provides a higher vapor pressure and its water is readily vaporized. The higher efficiency reduces the amount of heat input required, and thereby reduces the extent of heat exchanger requirement.
