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?
