Property Name (mandatory) Property Description and Allowed Values Property Value
Reference
Reference ID for this specified type in this project (e.g. type A-1 ), provided, if there is no classification reference to a recognized classification system used.
n/a
NominalCapacity
Nominal cooling tower capacity in terms of heat transfer rate of the cooling tower between air stream and water stream at nominal conditions.
0.
CircuitType
OpenCircuit: Exposes water directly to the cooling atmosphere. CloseCircuit: The fluid is separated from the atmosphere by a heat exchanger. Wet: The air stream or the heat exchange surface is evaporatively cooled. Dry: No evaporation into the air stream. DryWet: A combination of a dry tower and a wet tower.

CapacityControl
FanCycling: Fan is cycled on and off to control duty. TwoSpeedFan: Fan is switched between low and high speed to control duty. VariableSpeedFan: Fan speed is varied to control duty. DampersControl: Dampers modulate the air flow to control duty. BypassValveControl: Bypass valve modulates the water flow to control duty. MultipleSeriesPumps: Turn on/off multiple series pump to control duty. TwoSpeedPump: Switch between high/low pump speed to control duty. VariableSpeedPump: vary pump speed to control duty.
