Abstract: A solar adiabatic cooling vest. The cooling vest utilizes adiabatic evaporation to cool hot, dry air. Hot outside humid air is drawn by an exhaust fan through an air inlet over large particles of salt to lower the air humidity before passing through a wetted wick material. Heat in the air evaporates water in the wetted wick material, thus causing the air leaving the wick material to be saturated and at a lower temperature than the incoming air. The saturated air passes through a salt filter to lower the air's relative humidity. After exiting the salt filter, the cooled, drier air passes through an air filter to further lower its humidity and remove any salt particles from the air. The cooled air is then distributed through flexible outlet cooling tubes to a person's body, room, or enclosed space.
