how efficiently the user can utilize the software. Pipe2000 GUI
only for pipe system modeling Extremely easy to use The same for
all Campus Modeling projects

Control Valve Sets suction pressure Main pipes = 6 in. Buld. Pipes
= 4 in. HW C = 140
Slide 32
31 Modeling Chilled Water System Loads Flow Regulators simulate
valves which control the flows to buildings Supply side Hydraulics
determines the pressure available at the building Return side
Hydraulics determines the pressure required at the building to
transport water back to pump & chillers If supply side pressure
at the flow control valve is not sufficient the flow control valve
will open wide and provide less flow which can be accommodated by
the return side

46 Modeling Steam Distribution Saturated Steam Analysis 1)
plant provides saturated steam @ 100 psi 2) saturated steam is
distributed to all buildings 3) Load increases from low (400 #/hr)
to high (800 #/hr) Superheated Steam Analysis 1) plant provides
superheated steam @ 100 psi and 450 degrees F 2) heat loss
calculated using heat transfer coefficient = 0.15 3) select
Temperature Sensitive Analysis
