Thermal battery for summer

<< < (2/4) > >>

DBCollen:
solar thermal absorption cooling using calcium chloride and ammonia?
possible solution

MadScientist267:
Actually I've wanted to play with that kind of thing to see how well it really might work on a few levels but that's a fun one, mostly the ammonia. I'd also need more rooftop real estate (possibly, likely) but could maybe work out something for future...? Dunno

Pete:
If you drove the truck a bit and had a compressor on the motor you could use glycol to cool the bottles. Similar to what boaties use on their freezers. It depends on how often you drive really.
A tropical roof on the truck ( small gap above the roof with another roof above) would solve some of the problems with heat in summer, and may help a bit in winter with heat escaping. Depends again on whether you want to put a second roof on the truck.
Sounds like you have having fun with designs anyway.
Good luck
Pete

MadScientist267:
Here's the latest update...
Performing very well so far but still doing some optimizing.



Got the paper towel "lagging" put up on the intake duct, and a couple of probes now monitoring the aircon temps.

Intend to put 3 more inside the box, one at the intake, one center, and one at the discharge, to get a better feel for the characteristics of the bottles internally.

Pete:
Certainly appears that you are living up to your non de plume.
Good luck with staying cool.
Maybe in Summer you should camp near a lake and sleep on an airbed in the water.?
