*OSE's Design for a [[Dessicant-Humidifier Cycle Refrigeration]] based [[Hydronic Cooling]] system<br />
*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".<br />
<br />
=Basic Design=<br />
==Base/Frame==<br />
*Bolt Everything Down on Plywood?<br />
*Could also use PVC Piping to make tripods of sorts? (if not glued, this could allow for a portable unit of sorts?<br />
<br />
==Modular Air-Liquid Contactor==<br />
*Essentially a 4in PVC Pipe, Filled with "Bio Balls"<br />
*A submersible pump is in a sump at the base of the tower<br />
*A y fitting is used to attach a fan allowing for forced counterflow air<br />
*The return hose from the submersible pump is placed near the top, amongst some bioballs<br />
*The hose is then covered to stop mist/salt dust from escaping the top with the gas stream<br />
<br />
==Liquid Heat Exchanger==<br />
*Exchanges The "Closed Loop" liquid dessicant with the "Open Loop" humidifier-cooler, as well as with the final [[Hydronic Cooling System]]<br />
<br />
=BOM=<br />
==Column Packing==<br />
*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)<br />
*[[Bioballs]] would work and are inexpensive<br />
*[[Stainless Steel Scrubbers]] based packing would work as well (would a conductive packing offer any advantages over thermally insulative plastic? )<br />
<br />
==Fans==<br />
*[[Inline Fans]] may work, but the added pressure of a centrifugal fan should help with "pushing the air through the packed column?"<br />
*This ties into the spray tower vs packed column issue<br />

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