Are you ready for Stargate Command?

It's now early Saturday morning. I've had some time to look over the case. As I stated in my previous comment, I have a lot of work ahead of me. I already realize that some ideas have to be changed to fit the actual dimensions of this case. But none of that is bad, since the only thing that matters here, is that it works. So I have to take my time and carefully plot each step that must be taken, and the order in which to do them. Most of what I will have to do is assemble the parts into a unitized structure, and install them in prefabricated groups. Any major repairs will require careful disassembly. The fit of everything will be very close. There will likely be little if any space left over when all is said and done. So I will spend the weekend just looking this over, and making decisions on what to do next.

So for an update. I've purchased four, yes count them, four compressors. They were $19.99 each on Ebay. I brought them from the same guy who was selling Danfoss SC18CLX.2 compressors for $49.99 each. But they were are sold out. So I was looking for something to replace them. I got them from this link:

http://i2.ebayimg.com/04/i/000/ba/2e/bfc3_1_sbl.JPG

These should give me enough capacity to play with. As a result of their height, I'm changing the orientation of the case, again. Although, depending on how tall, or rather short they are, I may change the orientation again. I'll have to wait until I get and can measure them. If they are taller than 14", I will stand the case on what would be the binding, the location of the side hinges. However, if they're shorter than 14", then I may have the opportunity to lay the case flat.

I've also ordered two M30 plate brazed heat-exchangers. They measure 12" long, and can handle an extreme flow rate.

I will be using these as my liquid-cooled condensers. This is where the Mazzei 1585X Injector will prove very beneficial. I'll be able to force so much liquid through these heat-exchangers as to provide great cooling for my refrigerant. I will have radiators on the outside of the case to eliminate the system's heat. I'll now have to wait to get the rest of the components for this build.

And by the way, just for you bums who complained about not having pictures. I brought a camera, just so that I can guide you by the hand through my build process. That was money I could and should have spent on equipment. But I have to admit, having the ability to document the process will be beneficial. I just hope the damn thing works when I get it. I brought it on some police auction site. So I have no confidence in what I'm getting.

So there you have it. You can now once more whine about no pictures. And I'll ignore you!

I initially wanted to get the M60 plate brazed heat-exchanger. But because of them only being available in 3/4" NPT ports, I decided to get the M30, which I thought came in 1" NPT ports. As it turns out, the ports were in fact 1" weld sockets. Not good for me at all. So after consultation with the seller, I'm exchanging my order for the M60 instead.

http://www.dudadiesel.com/img/item/Mplatetopb.jpg http://www.dudadiesel.com/img/item/how_heat_exchanger_works.jpg

That's a good thing. Because the M60 will ultimately take up less space and require fewer connections. I really should have gotten it to begin with. By I mistakenly thought I would be able to connect the Mazzeis directly to the 1" ports on the heat-exchangers. Now that I know that's not possible, I'm getting the 3/4" Female NPT ports instead.

After reading the specifications further, I'm certain I also won't see a performance hit by using only one unit instead of two. So things should work out for the best.

EDIT: This shows the relative size of the heat-exchanger to the case.

Based on how good this guy has been, I'm making it absolutely clear who I've done business with for these heat-exchangers.

 

[Shingoshi]

The heaviest objects in my build will be the four compressors. And I just got the shipping weight for them, at 60LBS. So I'm guessing when the build is completed, it will be less than 150LBS. There really won't be anything else coming close to having the mass of the compressors. So two people should easily be able to lift/carry this unit when completed. And it does have it's own built-in wheels! So no problem.

This is the information that I've found for these compressors. I've been searching all over the web for as much as I can find. Seems these compressors have turned up quite a bit of interest. I found one link to spudfiles.com where one guy is using it for a potato gun!

The cooling capacity seems to be stated as 1535W. And being that I have four, that means I should have 6000W cooling capacity. That's a lot more than what I was thinking. But that simply means I have more than enough power to spare. And this doesn't even take into account that I'll be using CO2 and Propane as my refrigerants. Correct me if I'm wrong here, but doesn't propane have a higher cooling capacity than R-22?

I went looking (with Google) for information on my Rechi compressor, and wound up on the Spudfiles.com site. There's someone there with a great deal of knowledge about refrigeration. He gave this very detailed answer to one of my questions. Here's the link to his answer (http://www.spudfiles.com/forums/viewtopic,p,255906.html#255906).

Seems these compressors have many purposes beyond what we commonly think of on this site. And although I started this thread under case modding, what's going into this case for cooling is equally important as anything else. So here's the question I asked on Spudfiles.com.

Ok. So I need more clarification here.
1.) So I have a high-temperature A/C compressor. How does that affect my selection of available refrigerants? Like CO2 or Propane? Which refrigerant will give me the lowest temperatures possible while being usable/compatible in this compressor?

2.) What I was going to attempt to determine, is how this compressor would compare to an air-compressor in terms of CFM. I want to try to power a vortex tube with these four compressors. Running the first three in parallel into the final stage, would that give me the pressures needed for the vortex tube?

3.) I plan on using a liquid-cooled 60-plate heat-exchanger in place of a condenser. I was thinking I would need to in order to handle the load in a small space. I'm building my system inside of a Pelican 1780 Transport case. I'll still have an external radiator for the liquid-cooling loop.

4.) Do I need three pop-off valves? One between each of the four compressors?

His suggestion was that I run three of the four compressors in parallel, and feed the refrigerant into the fourth compressor (3:1). The purpose here is to increase the volume and pressure at the same time. So this would essentially be a two stage system.

Any of you here with ideas, please chime in.

Shingoshi

EDIT: I've had a few corrections given to the questions I had asked above.

2.)

The 4 compressors will provide plenty of pressure at moderate volume in a 2 stage setup. Refrigerator compressors are much lower power than a typical shop compressor so the volume will be much less. Most refrigerators are fractional horsepower in the 1/8 to 1/2 hp range.

3.)

For air, you are not releasing the heat of a phase change. Only the heat of compression needs taken care of between stages. Look at the cooling between stages on scuba and paintball compressors to get an idea of the size requirements.

4.)

You need 2 pop off valves. One simply mounts on the manifold of the junction of the output of the first stage. A normal shop compressor pop off is of sufficient capacity to handle the 3 compressors in parallel as they are lower volume than a typical 1.5-3.5 hp shop compressor.

The second high pressure pop off is for the outlet so if your pressure switch fails, the plumbing doesn't explode.

I just got my four compressors today. I'm really surprised by just how small they are. These things are really tiny. I've got all four of them sitting tightly grouped together inside of my Pelican 1780 Transport case. I haven't mounted them yet. I've only positioned them for the sake of orientation to see how much space I have to work with. I think easily I have room for one more compressor. Which would allow me to run a 4:1 first and second stage setup.

Maybe someone can tell me whether this would be good.
1.) Adding another compressor for increased capacity in the first stage.
2.) Having the 60-plate heat-exchanger between the first and second stages will cool the compressed refrigerant without fully condensing it.

I've taken a picture of them in their present arrangement with the reservoirs above them. But I won't be able to post any pics until I have a mini-USB cord.

Maybe you should have had the decency not to post obnoxious comments in someone else's thread, to the turn around and complain about highjacking.

 

[Naja002]

Frankly, I'm glad you haven't come back!

Sadly, I'm not the only person complaining of your constant and repeated thread-jacking. You can be assured that you are on fairly thin ice on at least 2 other forums, Shingoshi. The Universe is not centered around your ill-thought out, constantly changing project, so your attempts to constantly inject it into other people's threads is not only improper...it's gotten obnoxious.

TTIUWP is nothing new or original. That pic is not one of me and my friends .....it's quite popular across the internet. And if you look at it....it's actually quite humorous--that's why I use that one as opposed to other options. There's nothing "obnoxious" about it, except, of course, unless all you have is talk. You have your reservoirs? Pelican case? Compressors? Cool, let's see them. No, not more stock photos....let's see your stuff. Let's see some of your initial layout thoughts....via pictures. Let's see something besides just more mental masturbation. Your threads usually end like this one--with you talking to yourself. Ever wonder why?

You've been posting about this project in one form or another--for 2 years now.....not a single photo--anywhere. You used to be a photographer, but you have absolutely no camera? Really? Now you bought a camera, but no mini-usb cable. Well, radio shack is open.....what's the problem?

The problem, Shingoshi, is on your end. You're not the "Visionary Philosopher" that you think you are. You do not understand the things that you read to a point that will allow you to actually incorporate them...muchless mix them all together. You are going to need other people's help....knowledgeable people's help......you are closing those doors on yourself.

Thanks to you, I finally brought a camera. I have to wait until tomorrow for the mini-USB cable to arrive so that I can upload the pictures I've already started taking. You could of said this without having to post a picture.

The fact is you intended to be insulting, just as have been here. And I'm not the first person who has pointed this out to you. So please stay out of my threads, and I will definitely stay out of yours.

Got any links? If that's true....I would certainly like to know.

Edited to Bold the the important part.

Nice of you to silently edit pictures into the OP, Shingoshi, but you have a matter here that you need to deal with....See above^^^^^

You have made an accusation against my character/reputation and need to show proof....or admit your mistake.

After this issue has been resolved--I will refrain from participating in your threads as you requested. However, this issue needs to be resolved, so it's time for you to step up to the plate.

Aaaaaah, back to edit post #41 by adding some more pix. You're a pretty active guy for someone who apparently doesn't have time to just be a man and stand behind yourself....
