Abstract

An air conditioning device includes a body comprising an inlet plenum portion to receive input air including vapor molecules, a spray chamber portion to receive the input air, the received input air being rigorously mixed within the spray chamber, a sprayer portion to charge a liquid droplet and to release the charged liquid droplet into the rigorously mixed air to cause the charged liquid droplet to attract a vapor molecule, such that the vapor molecule attaches to the charged liquid droplet and separates from the input air, a separation chamber portion to cause the liquid droplet with the attached vapor molecule to separate from the rigorously mixed air and to condense and collect as liquid within an outlet plenum, and an air outlet portion to direct output air from the air conditioning device, a first humidity of the output air being less than a second humidity of the input air.

First claim
