I have been at logger heads with the designers for the past two years, my system has expansion vessel, degasser and pressurisation unit, my highest point is 10 mtrs and my lowest ground level. I have 3 turbocor chillers but only use 1 as my load is approx 280kw with a total design load of 740Kw...
I have a new system that seems to be suffering the problem of the chillers not being able to maintain the setpoint:
equipment:
3 turbocor chillers rated 550Kw each each with a fixed primary pump set at 19 l/s
3 secondary pumps with VSD however using two N+1 controlled by static pressure sensor...
