Re: Car Capsule for 77
Hi Michael
I'm in Markham, Ontario. Perfect place to have your garage freeze then open the garage door to 18c and 100% humidity, like last night. When it happened during the build you could actually see the garage interior haze over (the horror) as everything on the newly built chassis got a layer of condensation.
Alright, rather than continuing to speculate it's time to take a more scientific approach. The premise of the capsule is that their volume of air exchange alone prevents condensation, not humidity. I have the instrumentation to test this. I use hobo data loggers (ux100-011) to track temp/humidity in data centers so I'm going to take a sealed clear bag, stick it in the freezer with the logger inside, and find a tiny battery powered fan to create a similar air exchange such that when it's removed from the freezer the outside will instantly condense but the limited air exchange and air movement will keep the interior above dew point. The software does the dew point calculation so I'll be able to see after I download the data just how bad things got in the interior of the bag. The only thing I need to figure out is the fan for the air exchange; something small enough to simulate the 3-4x per hour exchange (a dead laptop comes to mind), and just cut a small slit in the plastic to simulate the zippers ( where the air bleeds out of the car capsule). That should give enough data to confirm or dispel the efficacy of the approach.
Cheers.
