RE: [PSUBS-MAILIST] Sodium Polyacrylate



Title: Message
George,
 
If you build a prototype dehumidifier I'll be happy to test it for you in the sub. I think condensation accounts for a lot of the maintenance load, as everything basically ends up soaking wet.
 
thanks,

Alec

Subject: [PSUBS-MAILIST] Sodium Polyacrylate

Ok, I can't find a pre-fab Hummidity filter made with this stuff anywhere online... I know that they are made... but my google-fu is not strong on this search.
 
SO...
 
I thought about how you might make one.
 
First and foremost, used product will have to be switched out from time to time, so the main filter component will have to be easy to get to and switch out.
 
Second to promote condensation and from there condensation inside the filter unit itself it'll have to be slightly cooler than the enviroment outside the filter... Problem... small refrigiration units are expensive (energy use wise)
 
So, what I think one should do is to use a pipe with a fan on the intake side and a normal air filter on the outflow side. that inbetween the intake and outflow has a copper coil with a simple fountain (12vdc) pump that pushes rubbing alchohol through the pipe at speed. Probably accellerated via a kort like nozzle off the pump. It wouldn't cool well enough for a air conditioner, but it should promote a cool atmosphere inside the filter which would promote water to condense within the filter. In the center of the coil which is inside the pipe would be a tissue bag full of sodium polyacrylate. That once used can simply be pulled out and replaced.
 
I'm thinking of taking a break from BugEye II to prototype this. Anyone interesting in providing a testbed if I do?
