I did the same thing. North Carolina, 1216, R13 in walls and ceiling, R4 in floor, about 5,000 BTU. Works great, even on the hottest days, and when running tools. The swamp cooler was about 6 feet square, it had a 5 foot tall fan blowing through some sort of paper strips that were being saturated with water being pumped over them from a large tank in the base. For all the water being evaporated I think the swamp cooler just made it worse inside the paint shop, and it made the paint jobs have problems. Just look underneath your car or air conditioner and you will see a puddle on a hot humid day. In fact modern cars run the air conditioner on low when you select defrost to remove the excess moisture. For those of us who dont want to lug an air conditioner in our trailers or tents, and where a swamp cooler wont work, or where you would need a 5. I took a few different ideas from Instructables. Being from Maine, I bought a new car without air conditioning, since we only need AC for a week or two up here almost 2. AC, saving about 8. Since then I got a job in central NH where the weather is much hotter than coastal Maine. I decided I needed some AC. I bought a used heater core off of fleabay for 2. When assembled as shown the heater core blew cold air on the back of my head, but was not enough to cool off my car with its untinted windows and blazing sun shinning in. I also thought my heater core was garbage as water streamed from it while it was running, after pressure checking it I found it was still good, I had been condensing tons of water out of the humid air. While this was a failure, I learned a few things, that if applied to a well insulated area inside my TD which if you made it a cube would only be 1. W X 8 L X 4 H will work as long as enough ice is used. I modified my air conditioner into a body cooler and now it works great, and the ice lasts forever. Step 1 What Are You Hacking TogetherI bought the 5. BTUs, the smallest ones for sale cheap are the 5,0. BTU ones, house and larger ones are rated in tons, this air conditioner will depend on how much ice you can put in it I found the marine coolers the best for what I needed as they tend to be all white less solar heat gain and much more rectangular with less bulk takes up space mine also has large easy to hold handles easy to strap into the seat belt in the car, and easy to carry full of ice and water it also has an external hinge, most hinged lid designs have a air leak around the hinge, the external hinge type have a lid that will lock in place even if you remove the hinges. Cherokee, I figured one from an SUV or van would have a larger heat exchanging area than one for a small car as many 1. PEX plumbing and fittings I used 38 but now I see 14 in some hardware storesTools drill and hole drills screw driverswire crimperspex ring crimpers if you use pex my crimper is a two part C shaped set of jaws that you squeeze using vice grips, it has spots in it to crimp 38, 12, 34, and 1 pex copper crimp rings. Step 2 Making Your Heatsinkjust like dark is the absence of light, cold is the absence of heat. Remove the hinges from the cooler lid, mine came off with screws so it was easy. You want the pump, wiring, and return tube, all connected to the lid so it can be left in place while you go fill the cooler with ice and water. Put the 1. I have has the nipple coming out the side, I used clear plastic tubing to connect on to the nipple, and then a plastic pex 9. I added a 9. 0 degree elbow to the hose to shoot the water at the opposite end of the cooler from the pump. RTVStep 3 Cooling Off a Tear Drop Trailer install the heater core where you want it, I plan on having mine installed near the top of the galley wall in the galley, with a vent into the TD sleeping compartment. I plan on one fan bringing in outside air all the time, and the other recirculating air from inside the TD. I plan on having my TD have two fans both running continuously, one bringing in fresh air the other recirculating TD bedroom air, and a wall thermostat switching the 1. This may exceed the amps rating for a normal wall thermostat but they also sell 1. V wall thermostats that will work. I use juice bottles full of water fill 34 full, dump in salt and shake until the water wont absorb any more, put the lid on and freeze with the bottle on its side leave a space for the pump I plan on making some sort of baffle to keep ice away from the pump put in enough water to cover the top of the pump. TD. since a TD is mostly used inside for sleeping, a cooler full of ice should last the night, however you will probably have to refill the ice and dump out most of the water from the night before. Since most campgrounds, and gas stations have ice for sale this shouldnt be too hard. I have posted this idea on tnttt. I used 1. 0lbs of ice and it lasted about 5 hours at 8. Tear maintained 7. He goes on to give ideas on how he wants to improve the design using a copper coil inside the cooler instead of a large bath of water, to do that though would require some sort of reservoir for expansion of the water, not hard, just a little more details, is all. Ible on how to heat a TD or tent off the grid, this gives a way to cool a TD off the grid. In fact ice was around a long time before refrigerators, my parents house is built in the area that an ice house once stood hundreds of years ago. During the New England winter ice was cut out of the pond behind their house and packed in straw and saw dust in double walled ice barns, the ice was even shipped all around the world in old sailing ships packed in straw and sawdust to be sold. Step 4 The Body Coolerthis is my current design instead of air conditioning in my car, it is a direct copy of this Ible https www. Too Hot Remove heat from your body with the Back only mine uses pex as the heat exchanger, this works very well, almost too well, I have had to unplug it more than once while driving on very hot days, as I found I wasnt sweating anymore and was starting to feel a little sick to the stomach.
