摘要：A fan control system suitable for use in air moving applications has a pressuresensor responsive to an air pressure in an air duct for supplying a static pressure signalrepresentative of the air pressure. A supply air flow sensor is responsive to an air flow in a
supply air duct and supplies a supply air flow signal representative of the air flow in thesupply air duct. A return air flow sensor is responsive to an air flow in a return air duct andsupplies a return air flow signal representative of the air flow in the return air duct. Asupply fan moves air in the supply air duct. The supply fan is driven by a supply fan motor.A return fan moves air in the return air duct. The return fan is driven by a return fanmotor. A unitary volumetric air flow controller is connected to the supply fan motor andto the return fan motor. The air flow controller selectively applies a supply drive powersignal to the supply fan motor to energize the supply fan motor, and selectively applies areturn drive signal to the return fan motor to energize the return fan motor. The powerdrive signals are responsive to the static pressure signal, supply air flow signal, and returnair flow signal.
