Constructor for FanAffinityLaws - Use this constructor when fan size is not changing.
- Parameters
-
| electricityCost | double, electric usage rate in $/kWh |
| driveEfficiency | double, Efficiency of the drive percentage (1 - 100) |
| motorEfficiency | double, Efficiency of the motor percentage (1 - 100) |
| flowPercentBaseline | double, Flow rate change by percent (0 - 100) |
| operatingHours | double, Hours for which the fan system operates per year - hours (1 - 8760 hours) |
| motorPower | double, Motor Power in kW |
| ratedFlow | double, Flow Rate in CFM |
| motorControlTypeCurrent | MotorControlType enum, current motor control for the fan system |
| motorControlTypeNew | MotorControlType enum, changed motor control for the fan system |
| flowMode | FlowMode enum, mode for flow change - by percent or by volume |
| desiredFlowRate | double, Desired flow rate based on flow mode If flow mode is volume desired flow rate is flow volume in CFM If flow mode is percentage desired flow rate is flow percentage (0 - 100) |
