Hi all,
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.
There is a pressure breaker (heat exchanger) on the 20th floors, and another chilled water loop circulating water on the upper floors (20 +), so there are no problems on this side.
Pressure on the lowest floors of the building is about 12 bar (static + dynamic).
What could be the feasible options to reduce the pressure and maintain it at a value below the 10 bar threshold on the lowest floors?
It would be possible to create another "zone" through the usage of another HX and pumping, but if possible, I would like to avoid this solution. Could a pressure reducing device in a certain configuration would work?
Thank you for the help and comments.
