Hi
just been drafted in to finish a chilled water system that is half way through installation.....loads of issues however one at a time......
The system is on a mixed use building - 170 bed hotel, ballroom, theater, art gallery lalalalala
approximate volume 1000m3 chilled water - with approximate 400 fcu's and 22 AHU's....
The expansion and feed tank, open tank is a floor below the highest point and is currently sized at 2 m3.
The temp range - 5/6 - 14 + Degs C. I would therefore add another 5/10 degs as a diversity factor.
QUESTION:
Can i add a pressure vessel? Can i reduce the overall size of the pressure vessel instead of the 2 m3? Feed for the system can be automatic on a pressure switch?
Any advice???
