A lot of trips. For the equivalent of a 12000 Btu/hr air conditioner (about what a lot of RV's have), you'd need ~40 lbs of ice per hour assuming the A/C is running 50% or so duty cycle.phil wrote:Unfortunately, it requires ice, so you'll be making frequent trips to Ice-atopia or whatever it's called.
Oh, you should totally try it with dry ice. Be sure to seal up your tent/car to keep the cool in.Absolut Jeenyus wrote:I wonder how long you could make dry ice last in that thing. Or a combination of dry and wet ice. The AC unit I use has to be plugged in, which isn't really a problem, but the less electricity I'm using from my genny, the less gas I'm burning. I'm always looking for alternative ideas... This is a cool lil contraption though.
I think I actually might. I have all the needed parts in the workshop. I think I may actually experiment with this. Im really interested to see how it would work with a larger cooler, and with the addition of dry and or wet ice... I like this a lot... Ive messed around with some other contraptions... Like a basic oscillating fan with copper tubing wired to the back of the fan and having cold ice water punped through the tubing with the fan propelling the cold air. The only problem with this is you need to recycle the water that has already run through the tubing. And there are way to many unsecured parts... Im interested to see what could be built off of this idea...Jiva wrote:Oh, you should totally try it with dry ice.

I think Jiva was refering to the CO2 offgassing and your asphyxiation in the sealed up car/tent.Absolut Jeenyus wrote:I think I actually might. I have all the needed parts in the workshop.

Yes. Also dry ice has a significantly lower heat of fusion than water, so even when you factor in the gaseous CO2 coming to room temp from -78 C it still won't cool as much per pound as ice.SilverOrange wrote:I think Jiva was refering to the CO2 offgassing and your asphyxiation in the sealed up car/tent.Absolut Jeenyus wrote:I think I actually might.

Well now that we know why you go... Other people go for their own reasons, some to try experimental ways of AC. lol. Besides there are uses for AC out there for people who have young children, or people with medical issues where the extreme heat is too much. My mother for example has something called RSD and would be impossible for her to get along out there without having a climate controlled area.unjonharley wrote:A/C? WTF?

I go to Burning Man to be outside and enjoy the weather.
I'll give the one I got a try this week. Monday or Friday since I'm off these days. Since I'll be using it to cool a regular cab 1995 Ford 1/2 ton (F150), I think it'll work fine. I might even see how good it is in the bed which I have a camper shell on since thats my sleeping quarters during the event or any time I go out kicking around Nevadas backroads. I would'nt use it in a tent either or even an RV since that would be to big as far as cubic feet go. The one I got runs on 8 D cells, permantly installed rechargeables, the vehicles battery, or a house current.Stickygreen wrote:inside a vehicle, or RV might work? i'd be interested to hear any updates after the burn.

. I tryed it today and it was fair at best just cooling the cab so it would be pretty much useless in cooling the bed with a camper shell much less an RV. I hope phils homemade job is better.
