Awesome new cooling idea, and it works this time!!!!!!!

if you do carry this out, be incredibly sure to keep me updated

but why those intense materials? why not just some WC tubing with a simple copper condenser? no pressure is added, but it is mostly taken away. there are not really requirements for low pressure components, only high pressure

and 30" of Hg is super high pressure, the point is very low pressure. And what does that 24cfm rating signify. i need to learn a little about vacuums, care to inform me a little?

the vacuum pump I'm using is used to get the contaminents out of large chillers and refrigeration units. The 24 cfm is how much air it can move. If I used a 3 cfm on a 300 ton chiller(which is still rather small) it would take forever and a day to get it down to the required 5 micron. using a pump with the capability to move 8 times the capacity speeds things up a little bit. I'm using this kind of equipment because the pump collapses wc, even as it first starts. I have seen it collapse copper coils in self contained heat pumps before when one of my coworkers had mistaken it for the 4 cfm pump for the smaller units. I looks the same except one has a big "24" spray painted on it and the other has a big "4"....idiot cost us $30,000

In case you're wondering, I would use the 4 cfm pump but it loses its ass at 7 microns on 10 ton units.

can you find a cheap vacuum pump for around like $30 that could achieve 2" Hg?

bldgengineer · 03-16-2007, 07:07 AM

maybe a hand operated one? I.E. the kind found in sex shops

joeswm8 · 03-16-2007, 07:13 AM

lol yeah okay! no... lol

can you find some links. i mean if a syringe got me to get water to boil at 60C i might as well just use a strong syringe again. i am just looking for a nice vacuum pump.

this one is so cheap that there is nothing i could lose from buying it

I was with you all the way with the first few posts, now I'm lost but I've read every word.

Keep it up guys, makes a change to have something good to ponder over.

How many inches of vacuum are you hoping to pull? A vacuum of 9" is easily destroyable. When I work on the train I can pull the bag off at 9". A good vacuum is about 15" and if you only use it at a couple of inches you'll have a decent unit that won't blow out at least...

You could use one of these if you wanted 21":

Your trying to build a heat pump, what you works better because trying to vaporise and condense water in the same system can be explosivly dangerous in the sense that you could shoot a pipe off, also maintaining a flow is also difficult. A better way to do what your doing is pressurise the water before it enters the radiator, thus heating it up. Or accually in this instance to make the pressure differences able to be as much to gain and absorb heat you need a refrigerant. But anyways pressurises it so it gets hot, then have this pressurized collant pass through a choke point into larger pipes, these are your cool ended pipes, run these to your heat exchangers, then into a holding tank, then it goes to the pump is pressurized and releases its heat all over again. Bassically an refigerated computer, same concempt of pressure differences, only instead its reversed.
