It's coming from a hotter body to a colder body....... So, you just DON'T get it at all do you? You keep forgetting about this little piece of equipment in the way, the HEAT EXCHANGER. Yes, the ambient (hotter) is flowing to the chilled water (colder) up until the point where (you say) the water can become warmer than the ambient. Once you make the statement that the chilled water warms to the point that it exceeds the ambient you have violated the 2nd law. At that point you are saying that heat is passing from a colder to a hotter body. |

Portable AC - Swampy Cooler
I haven't bought one because they don't work, endless ice supply
needed. 20 pounds of ice @ 144 btus heat of fusion per pound is 2,880 btus. Raising the temperature of cold water would provide a bit more cooling. So it's about a 3000 btu air conditioner for one hour, assuming its heat exchanger setup had enough throughput to melt all the ice in one hour. An AC air conditioner, for example the "Marine Air Portable dockside AC unit effectively cools cabins on boats 20'-30'; 6,720 btu" so it's half the cooling of a *small* air conditioner (ignoring dehumidifying effects, we'll assume it's 100% humidity on a stifling day in Panama). Pretty lame, I'd suggest putting the ice in bags and sittin' on 'em. Stretching it to last 10 hours would require 200 pounds of ice, or an output drop to 300 btus an hour, typical cooling capacity of a 12 volt Adler Barber Cold Machine air cooled reefer setup goin' full blast. Not much if you're trying to cool a boat, test by opening up your reefer and blowing a fan on it. Beware, they also make evaporative type "Swamp Coolers", which *do* work great in low humidity areas like the desert. My Dad had one with an intake cowl on it (no electrical wires) that fit in a partially unrolled window on his '69 Jeep Wagoneer; you had to pull a cord periodically to rewet the evaporative pad. At 60mph, pullin' that cord resulted in a blast of cold air! Also had to refill it often if it was ragin' hot and dry. The only 12 volt AC I've heard of that might work is one that sucks up water 10 feet below your boat, hopefully below a thermocline, and runs air through a heat exchanger onboard. Pricey though, cupronickel tubing. |

They don't work if there is a lot of humidity but in dryer areas they are great. A few things to note if you do go the way of the swamp cooler. Keep all of your windows open, they need a lot of air circulation and keep plenty fresh water in it. They sell small ones and most of them out there today have all of the pumps and fans built in. They are also relatively inexpensive and easy to repair plus they use less energy than AC. I used to work at Home Depot in So Cal and you wouldn't believe how many people used these in their homes. I got one because of low energy usage for a room that didn't have air conditioning in my house. It worked great. -- Message posted via http://www.boatkb.com |

If you are pumping 90 degree air into that cooler, what difference would it make whether or not the container was insulated??? Try it. Take a given amount of ice and put in a ice chest. Place another in a cardboard box. Blow the same exact amount of air into each, with the same exact equipment, and the same exact exhaust. Measure the temperature of the exhaust. Guess what? They'll be the same. You really are that dumb. \Well, damn! Tell me HOW in the hell insulation would help if you are pumping the exact same are that you are trying to insulate FROM right into the cooler!!??? Again, see my last two sentences above. Try it. Everything exactly the same except for the container. And again, if you are pumping the same exact air into the chest that you are trying to insulate from, just what IS the insulation doing? Take this for instance. Take a piece of isopolycyanurate insulation outdoors. Take the temperature on one side of the piece. Take the temperature on the other side of the piece. Huh? They are the same? Imagine THAT! That is exactly the scenario you'll see with the ice chest. You are pumping air into it that is exactly the same temperature as that that you are trying to insulate against. Dumb indeed! "isopolycyanurate"? Let me help you with that big word... Polyisocyanurate. It's sold at your local Home Depot under a variety of brand names. IIRC, the R-value is 7.2 per inch - one of the best for home sheathing. -- Uh, it's not a word, it's a combination of abbreviations, thus doesn't make a hoot which order. Keep telling yourself that. I've seen many, many documents with the abbreviations in both orders. They were wrong, too. But, hey, you've followed me to another thread!!!! Infatuation....... Infatuation...... It's driving Dan crazy.... It's making Dan CRAAAZZZYYY.... I follow you to EVERY thread, remember? Got to keep your stories straight, boy. -- "It is common for persons with an infatuation disorder to suddenly, and without provocation, act as though they dislike the very person they are stalking." Infatuation...... Infatuation..... It's driving Dan crazy.... It's making Dan CRAAAZZZYYY...... How much time did you spend on that? About 10 seconds. Why? I know you are infatuated to the point of stalking, but do you need to know every little detail of my life? Sounds like a sickness. -- Yes, you DO have a "sickness" and there are professional people that will help you with your infatuation complex. 10 seconds? You felt compelled to Google some quote and you did it in 10 seconds? Amazing. Good job, boy, now go clean your room. Comical.....typical kevin doing exact;y what he has whined about others doing to him......and he wonders why he is still "king of the ng idiots" |
