Re: [PSUBS-MAILIST] Snoopy life support test

That's an interesting work around but keep in mind that depending upon the space between the tube and canister you could end up with non-uniform pressurization causing inconsistent transfer of CO2 to the granules and inefficiency.  A stronger fan might do just as well although power consumption will go up.

Given that Alec had the scrubber at the aft head and both occupants were facing forward, I can't help but wonder if placement is contributing to the inefficiency of cleaning the cabin.  A forward fan, pointing backward, would help move CO2 aft and toward the scrubber.

Sean makes an excellent point.

With that in mind, maybe we can combine the two ideas? By inserting the canister into a larger tube and then directing the blower to pressurize the space between the two? That way, the larger scrubbing surface will be absorbing CO2 at higher partial pressure and the fan will be operating at higher efficiency.

 

Maybe I could build one and we could test it?
