Sound waves may be the future, but this is how it's done today.

hooollyyy....

Nice stuff, frozen.......

Are those Mycoms? I haven't seen columns, glasses and drums like that since I was at D/B years ago.

Cool. :)

I am not familiar with mycoms ice? The screws are Fricks. Controls Allen Bradley. That controlled pressure receiver column supplies minus 25 sub cooled liquid to the flooded evaporators. People have asked me why it is so tall (15’ feet). They don’t understand when I tell them it increases sub cooling, because of the weight of the column liquid increasing pressure at the bottom.

When the liquid from the accumulator moves via transfer tank to the controlled receiver. They just about wet themselves.:)

Mycoms are Jap screws. Nice stuff, actually.

That CP receiver is actually a flash tank fed by a high side float and is vented off to the interstage or economizer port, no? If so, the liquid at the top of the tank is at saturation and every foot of height adds to the static pressure gain at the bottom......hence the subcooling.

Is this a pumped liquid overfeed recirc system? You need that height on the CP receiver to minimize cavitation at the pump inlet. If it uses alternating H.A.Phillips pumper drums this isn't as much a problem.

The transfer tank between the accumulator and the CP receiver.....is that a pressure driven pumper drum? Sounds like a H.A.Phillips deal.

I never really had much of a chance to get real down and dirty with systems like this. It's just fun to look at and BS about 'em. ;)

It’s not pumped liquid its pressure fed. The transfer process is also pressure fed via a little burst of discharge gas. The high-pressure receiver gets all the return liquid from the condenser. This receiver feeds the medium temp coils on the loading dock. The excess return liquid is transferred from this receiver to the controlled pressure vessel via float-controlled valve. Two thousand pounds of R-22 makes it all work.

It is challenging, I am just starting to get comfortable with it myself.

It sure sounds like a Phillips system. http://www.haphillips.com/products_systems.html

Don't you mean 2000# of R22 and one knowledgeable guy to make it all work. ;)

25 years ago I really enjoyed long conversations with Herb Rosen and John Souza at H.A.Phillips when I was at D/B working with some of their valves, float controls and humongous pressure vessels on a couple of really wild projects. To see pics like these really takes me back.

If I ever get to Melborne maybe we can have lunch.

Frozensolid - Can you tell me where this is? I'm interested in finding out about CPR/gas transfer units that are still in use. Most designers like pumped overfeed, but it seems there are a lot of operators that like these. It's what they grew up on, I guess. Do you know of many such installations?
