Two section vertical condenser
Hi
Have two section vertical condencer with two inlet and two outlet conections.
There are interesting question: how does arrange pipelines?
I suppose that for properly condencer work, pressure drop of the sections with their connection pipes must be equal, but there is different heights in wich they situated.
Could you check my solution please?Last edited by Aik; 13-07-2010 at 07:09 PM.

Re: Two section vertical condenser
Hi there,
This kind of condensers are designed for two separate cycles (compressors), each section must be connected to one compressor.
If you have one compressor and want to connect it to this condenser then there is no problem.
If you have head pressure control (fan cycling) then you have to turn off/on the fans in pairs.

Re: Two section vertical condenser
Thanks
In my system there is one refrigeration cycle for two sections.
Hot gas distribution must be the same in both sections. One section situated higher and condencing pressure will be less then in lower section.
It's my opinion... could anybody tell about arrangement of pipelines in thise case? Or may be there is any recomendations?In some places will have to think ...

Re: Two section vertical condenser
Aik, Lana, you can connect both together but I will have to make a schematic of it.
This evening or tomorrow when I have a free day here in Belgium
You have to use a siphon to overcome pressure difference.
Or you may enter your discharge in the middle and split both with equal length to both coils and outlet both at the lowest part
But with a siphon, you're sure.
Or I can scan the relevant pages from Ind. Refr. from Stoecker.Last edited by Peter_1; 14-07-2010 at 08:10 AM.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Two section vertical condenser
Thanks Peter_1.
Thise for ammonia systems or for refrigerant such as R404a, R22 and etc.?In some places will have to think ...

Re: Two section vertical condenser
The natural phenomenas regarding pressure drop and pressure losses remains valid for every circulating liquid. So the solutions are valid for every refrigerant.

I'm sorry I meant "If it's just one condenser with 1 circuit you will not need it"

Re: Two section vertical condenser
Aik, have you ever tried to fill a bottle with streaming water where there's no possibility that air can escape out of the bottle to replace the filling water? This won't work.
Or what if 1 l/s arrives in the receiver from eh codennser and only 0.8 l/s is leaving the receiver? (or in other words, more liquid coming in then going out of it) You will have a pressure buildup and the liquid will backup in the condenser.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Two section vertical condenser
You can also communicate the upper part of the receiver (vapor) with the liquid separator/surge drum with pipe of very small cross section. The surge drum is connected to the LP, which is a much lower pressure and so the liquid receiver will be at a lower pressure than the condensers and so the liquid can be drained without a problem (no equalising line is needed). However with this method more energy is spent / less capacity plant because part of the vapour sucked by the compressor is from the HP, where it should be condensed.
