*OSE's Design for a [[Dessicant-Humidifier Cycle Refrigeration]] based [[Hydronic Cooling]] system
*May be possible to control it in a "dumb" system (ie just turn the power on/off) since the pumps would be self priming, and the fans can be turned off/on easily, and everything should be using AC power all linking to a single "power bar".
 
=Basic Design=
==Base/Frame==
*Bolt Everything Down on Plywood?
*Could also use PVC Piping to make tripods of sorts? (if not glued, this could allow for a portable unit of sorts?
 
==Modular Air-Liquid Contactor==
*Essentially a 4in PVC Pipe, Filled with "Bio Balls"
*A submersible pump is in a sump at the base of the tower
*A y fitting is used to attach a fan allowing for forced counterflow air
*The return hose from the submersible pump is placed near the top, amongst some bioballs
*The hose is then covered to stop mist/salt dust from escaping the top with the gas stream
 
==Liquid Heat Exchanger==
*Exchanges The "Closed Loop" liquid dessicant with the "Open Loop" humidifier-cooler, as well as with the final [[Hydronic Cooling System]]
 
=BOM=
==Column Packing==
*Should be simpler than a [[Spray Tower]] system due to it's "open" nature (even if in a sealed+clean container, it doesn't have a sealed pressurized liquid tube)
*[[Bioballs]] would work and are inexpensive
*[[Stainless Steel Scrubbers]] based packing would work as well (would a conductive packing offer any advantages over thermally insulative plastic? )
 
==Fans==
*[[Inline Fans]] may work, but the added pressure of a centrifugal fan should help with "pushing the air through the packed column?"
*This ties into the spray tower vs packed column issue

==Power Distribution==
*The fans will run on AC power, so a "power bar" style surge protector should suffice
 
==Pumps==
*"Fountain Pumps" usually go for ~20-50 usd each (need to determine [[GPH]] flow needed/diminishing returns on higher flow?)
 
==PVC Pipe==
*4in PVC Pipe seems like the largest size at the local "Home Depot" store
 
==PVC Pipe Fittings==
*Will need a Y fitting at the base to have the sump seperated from the air inlet
*Also want caps for the sump
*Any fittings for the tops?
