12 volt dc air conditioner

My homemade air conditioner run off 12 volt battery's, which are charged by my solar panels. Viewable in my other videos. When global warming (Summer) arrives I will retire my solar furnace and use my homemade AC.
It uses eight 2 liter plastic pop bottles pre-frozen in the freezer. I plan on having a total of 24 bottles frozen so I can rotate them as needed. This unit is for the rec-room t.v. room and is limited by the length of the cord hooked to my battery's. I plan on making a AC model so I can cool the bedroom. Fan is a china built 12 watt 2 speed model maybe six inch's across. One 2 inch pvc fitting screwed into quarter inch plywood.

Shouldnt u léave more space so air can circulate better inside the cooler?

[mariasman100]

Lots of nonsense in the comments here. First, this is not going to cool the interior of an automobile effectively. The a/c compressor in cars and light trucks are 2-4 ton units (167-350 pounds of ice melted per hour). A cooler filled with ice bottles doesn't even come close. Second, the energy consumed by the fan is negligible. Do the math. There's nothing wrong with the idea... it's just that the cooling capacity is very limited. Spot cooling might be a good use.

@luigi2999 Thanks, right now it has been put away for winter storage but when I get it back out I will try that.

@wduane2807 try it again, but this time, after you put in the frozen soda bottles or ice, pour some salt over the ice. It will lower the temperature at which ice will freeze, and, henceforth, make the output cooler, and last longer.

Why would you insulate the top? are you afraid some of the "cold" that is inside will get out?!? lol Isnt that kind-of the point?

another stupid redneck

[wduane2807]

Tried that, a truck with no a/c and that was a waste of time and money.  It had a cool breeze but that did not last long and there was no temperature difference in the cab of that truck. I ended up turning it off and rolling the windows back down.

@dubbified There may be some validity to what you are saying but imagine this in a car with no AC when you have no alternative or while camping when you have no alternative. This would be perfect.

[longp2000]

Awesome video. I know that some people are going to tell you that freezing water takes too much energy etc but if I were camping in here in Texas, I'd use that in a heartbeat. This is the best design I've seen and the fact that you are running it off of Solar to Batteries is awesome.

This is a good example....but you also have to consider the power consumed by the freezer to make the ice....generally I like the idea....also do you have the discharge cfm info....I guess you need to upgrade that too.....
