Hi again russ,
Sorry for late answer!
- There is no problem atm, let's say that by maintaining pressure under 10 bar, I could be able to do a little twist to the system which bring interesting energy savings
- The pumps are indeed controlled with VFD. However there is no DPT neither logic...
Hi russ, thank you for taking the time to answer.
That is correct, secondary pumps are circulating chilled water through the AHUs. Current pumps are oversized and rated with a total head of around 4 bars, which brings the pressure around 12 bar.
My question is more like this: Is there an option...
I am new on this forum, hope you are doing good.
I have a question related to a project I am currently working on.
The system is a 40+ floors mix used building, with a cooling system composed of a couple of centrifugal chillers, and a primary/secondary pumping configuration.
