Constant Primary and Variable Secondary Chilled Water System with bypass decoupler pipe

[mdzakeers]

Gents,

I have a design drawings from one of our consultants having constant primary and variable secondary chilled water system. I looked into design and arrangement of valves and fittings around chiller and found lot of discrepancy.

I request your help me and if you can provide me a design drawings from your any previous projects showing complete set of valves and fittings required at chiller inlet and outlet including primary pump and secondary pump arrangement with Decoupler line.

I would be much thankful to u.

Thanks in advance.

Why don't you ask your consultant for clarification? Using one design to partially modifying another design without really knowing how any of the two were designed, is asking for trouble. You can find sample schematic loops of various constant primary and variable secondary loops online.

Lots of ways to do it but here is one reference.

ASHRAE has everything you'd ever want to know about hydronic systems including different types of variable flow systems.
