chilled water system ring line
chilled water system ring line
(OP)
I have been asked to design a chilled water system ring line to connect 5 dry condesors to a cold water system comming from a low loss header. The ring line seems to have advantages over one single line with brach connections to the condensors. It also seems that pipe parts can be replaced qwithout having to stop the unit, by placing them in the correct position. Can some body tell me more about thesa advantages and where to put the valves.
Thanks
Thanks

For the return line there is also a ring for the same purpose. Well Maybe I have answered my own questin now, but if somebody could confirm and add to it would be nice.

Generally chilled water systems are fairly indestructible unless you are worried about terrorist attacks, atom bombs and earthquakes. There could be a lot of expense for extra piping and valves which never would pay a benefit.

You will need to maintain the main pipe size in order to feed from both sides, watch you water velocities at the end of the loop (where the two sides meet). Velocities will be so low, you get laminar flow and thus cannot remove air from system, keep water velocity above 1.5 Feet per second.
Why are you doing a closed loop?

If all coolers are to remain operational and you want to be able to isolate any section of the ring main you will need to located an isolation valve on either side of each cooler take off.
It is an expensive method but if the system operation is critical or need to allow for future expansion then it works well.
