Hi,Its hot and I got a lot more jobs I need to do this summer with no air conditioning. Ive already landed in the hospital one time due to dehydration and over heating. I will literally go through a gallon of water within a few hours.I was thinking about doing a dry ice cooler but abandon the idea due to the impracticality of storing the dry ice/high prices and availability. It also seemed very inefficient when I saw how it was produced.I'm thinking why not just hook a hose to a small (2.5 lbs co2 tank) allow it to leak into antifreeze (or window washing fluid) then using a water pump and fan to circulate it through a radiator from a old a.c. or car oil cooler. Last ill use a 20 ft plastic hose to release the co2 outside of the room I'm cooling.So what I need to know is what is the cooling capacity (in btu?) Of the co2 in a 2.5 lbs tank?How inefficent will it be considering I need to release the co2 to stop my tank from exploding. Does any one have any idea?Thankshttp://imgur.com/a/B47eu via /r/DIY http://ift.tt/2uzGxO4
