Open Source Humidity Pump

Basics

• A Device Similar to a Heat Pump , but for Humidity
• Uses barely any powered componets, and just needs a heating source for hot "regenerating air"
• Could be used in a pulse system, or with 2+ modules for continous flow (Similar to Pressure Swing Adsorbtion )
• This design is for a solid, regenrable dessicant (most likely Silica Gel ), although an adaptation for a Liquid Dessicant is possible

Flowchart

Controlled Side Unit

• Similar to a window mounted ac unit in form factor (unless if used as an embedded componet in a larger system
• Screen for Humidity Set Level, and Current Level Info
• Air in/out
• Optional Distilled Water Collection and/or Piping

Dessicant Bed

• Can be any sort of Packed Bed
• Most likely a packed box, or pipe of some sort
• Ports for:
• Air In (Regenerating, and Process Air)
• Air Out (Dried Air, and Ultra Humid, Hot Air)

Switching Units

• One on each side
• Will standard solenoid valves work?

Blower Unit

• Will cpu fans work/
• Need to do math on m^3/sec to %humidity removed and make some calculator (useful for design, and control code)

Optional Water Recovery

• As the "regenerator air" 's output will be heated, (near) saturated humidity air, it can be cooled (to ambient, or below), to extract Distilled Water for little energy
• Would require heat exchangers at least (a water tank, or air, and a heat exchanger/radiator for cooling may work for passive cooling, active can be any of those systems)
