	*A type of Refrigeration Cycle that uses a combination of evaporative cooling (endothermic cool end), and dehumidification via dessicant(s) (exothermic hot end) to pump heat
	*Can be used for [[Solar Air Conditioning]]
	*Is also advantagous in it's design, and material simplicity

	~~=Plotting=~~
	*Should the columns be randomly packed, packed, spray, or some hybrid
	*Little info on water evaporation (That [[User:Eric]] has found so far )
	*[https://www.aiche.org/system/files/aiche-proceedings/conferences/404771/papers/483651/P483651.pdf A Whitepaper on CO2 Scrubber Tower Design] (this was for co2 scrubbing via amonia absorbtion but compared the Spray Towers and Packed Columns)

	~~=Process=~~
	~~[[File:Dessicant AC Diagram.jpg]]~~

	~~==Evaporative Cooling Collumn==~~
	*Room Temperature air is pushed in to a counter flow water sprayer collumn with mesh/[[bioballs]]
	*The water evaporates and cools the air (at the cost of increased humidity)
	*It is then sent to the Dessication Collumn

	~~==Dessication Collumn==~~
	*This works in a similar manner as the Evaporative Column, but it has the opposite goal, Dessication of the Air Stream
	*It does this via a dessicant, most likely a [[Liquid Dessicant]], due to ease of operation
	*Produces Fully Dry Air, and Saturated Dessicant via Liquid Dessicant
	*Make an identical unit to the Evaporative Cooling Collumn, and replace the water with ?percent concentrated calcium chloride solution
	*Air sent to Humidity Control Collumn (Optional), Liquid Dessicant sent to Regenerator

	~~==Humidity Control Collumn==~~
	*This takes the Fully Dry Air, and brings the humidity up to comfortable levels
	*It can use OTS humidifiers, or be a smaller version of the Evaporative Cooling Collumn
	*This stage is OPTIONAL

	~~==Dessicant Regeneration Module==~~
	*This is a module where the Saturated Liquid Dessicant is Heated to Concentrate it and thus regenenerate it.
	*Passive solar is promising, but any heat source will do
	*Also heat exchangers that utilize waste heat from the process for regeneration may improve efficiency further
