Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | PFan_Q_flow_nominal (from BaseCoolingTower) | -0.05 | Ratio of fan power to provided cooling at full load (negative as Q_flow_nominal<0) |

| Advanced | |||
| Real | ratCooAir_nominal (from BaseCoolingTower) | Coolant-to-air mass flow rate ratio at design condition, used to compute air flow rate for UA_value | |
| Buildings.Fluid.HeatExchangers.CoolingTowers.BaseClasses.Characteristics.fan | fanRelPow (from BaseCoolingTower) | Fan relative power consumption as a function of control signal, fanRelPow=P(y)/P(y=1) | |
| Real | fraFreCon (from BaseCoolingTower) | 0.125 | Fraction of tower capacity in free convection regime |
Components
| Type | Name | Default | Description |
