31. 30 Chilled Water Model Supply Return Chillers & Pump Flow Control Valve Sets suction pressure Main pipes = 6 in. Buld. Pipes = 4 in. HW C = 140

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
