Poor man's A/C

Bryan (SixPapaCharlie) is building his 2nd one of these. Version 2 seems to be a lot more sophisticated than version 1, though I haven't been with him when he's tried it out yet. The first version worked but not for long, as it burned through the ice pretty quickly. I don't know remember what all he's done with this new one, but it's supposed to be better. I'll tell him to chime in here.
 
Apparently leaving the door open is a foreign concept. I've been on the ramp when the air temp has been over 115 degrees. Door open. Air movement. No big deal.
 
He'd better post pics with detailed blueprints or else we'll be convinced it never happened :yes:;)

Any of you have one of these? Or something similar? Are they worth the hassle? I'm talking only for ground ops and not for altitude.. Your thoughts?

Yup. Same one. And, Yup. Get the remote unless you have an easy way to unplug in flight or disconnect power. Makes Dallas summer heat a bit more bearable. If the wife is in the plane with me, she gets the nozzle pointed at her. It isn't as good without the direct airflow.

This is what I am working on. It is a closed loop using Antifreeze so no sending water/antifreeze back on top of the ice.

Works with a 12v battery or can plug into plane A/C outlet
Broken into 2 sections (wet and Dry)

The coil on the left is where ice / dry ice can be put and it has it own lid so the air being sucked back in does not blow onto the ice.

The hope is without re introducing water and warm-ish air to the ice, it will stay frozen much longer and if Dry Ice is used, there is no mess at all.

The rate at which the dry ice creates C02 is slow enough that it won't build up. (maybe if you were in a smart car with windows rolled up. But even then doubtful)

I upgraded from a 190 CFM fan to the 240 CFM fan which is what I think all the commercial products use. I have no intentions of ever trying to make these to sell or for anyone else but I will gladly tell you how I built it and how it is working. I like to tinker so this is one of those "work is its own reward" things for me.

The wiring is the biggest PITA. That, and loading the loop w/ antifreeze. Getting all the bubbles out of the system was a mess.

you are looking about $100 in parts here:

Wow nice job! Thanks!!
 
Bryan... I'd like to see your system in person someday soon.
