- Heated solution evaporates hot water vapour from the generator chamber (desorber) (could be solar or geo heated) is attracted to the cooler condenser chamber which is usually paired with a chilling tower to reject heat (29C) to outside, with the left over concentrated desiccant solution pumped back into absorber chamber and the condensed chill water pumped into the evaporator chamber
