Cooling return water for circulating pump

[augiecrazy8]

The searches I did for this idea brought back a few pages that were similar to what I'm thinking, so I'm going to lay this out there. In college we had a water trough that could feed water to 10 different spouts so we could all grab a drink at once (football player). The water was fed through a hose into a copper condenser coil that was placed in a cooler that had ice thrown around the copper to cool the water. Im thinking I could so something similar with a circulating pump for my liebig. As the water exits the liebig it runs through a copper coil that's in a small cooler filled with ice. Its then spit back out into the circulating pond and reused again. I know there are much smarter people than me, so lets hear thoughts (or just links to discussions that have already happened that I couldn't find).

I dont see it working,any diferant than pumping out of a container.but that would be a idea for those that want to use a pond/pool or other supply that they don't want running threw pump/cooling system .

Excuse me while I play with this.

The latent heat of fusion of water is only 15% of the latent heat of vapourization. So if you have 1 kg of ice in your cooler, that will convert 0.15 kg of steam to liquid. In a typical run using 25 liters of 10%ABV wash, you would get about 8.33 liters of 30% product. That 8.33 liters will be 70% water or 5.83 liters of water, which, when vapourized is 5.83 kg of steam. If 0.15 kg of steam need 1 kg of ice, then 5.82 kg of steam require 39.4 kg of ice. For ethanol 1 kg of ice would convert 0.40 kg of ethanol vapour to liquid, so 2.5 liters = 2 kg ( SG = 0.8 ) of ethanol vapour would require 5 kg of ice. So altogether you would need 44.4 kg of ice. This is disregarding atmospheric melting of the ice, so you would probably need 50 kg of ice, to be safe.

Another way to look at this is that the heat that you apply to the boiler (1000 W, say) is going right into your cooler of water and ice via the liebig coolant flow. So your cooler of water, in effect, has a 1000 W heater right in it. Your job is to keep adding ice to the cooler to keep its temperature tepid.

The football players' drinking fountain used the latent heat of fusion of the ice to cool water, not steam. The specific heat of water is only 1.25% of the latent heat of fusion. You do the math... (a la Rad)

Here are the tables for the latent heats:

i think people are over thinking it. your just trying to cool the hot water thats comeing out of the condser right ? i did something to that effect. search "water cooling idea" i made one have been back to post on it sense i have got the to really work . but check it out if this is what your after i will see if i can put a link on this post

try wacabis swamp cooler heres a link http://homedistiller.org/forum/viewtopi ... =2&t=30150

Why do so many people think that thinking is bad? Thinking is fun.

Now will some other funster play with the footballers' drinking fountain?

Take a car radiator with electric fan and use it for cooling your circulating water. It works extremely well.

I have a brand new transmission cooler sitting around for a project that never materialized. Would that work, or would it be too small to be effective?

[HolyBear]

I think it would work like a champ!

[lustreking]

Cool (pun intended) I'll give it a shot.

I use an old motorcycle/dirt bike radiator with a fan and run my condenser water through and it works great.
