ABSTRACT:
An efficiency matching device and method. The efficiency matching device is utilized in combination with a centrifugal fan adapted to deliver an air mass flow through an air delivery system. The fan has a housing that defines an inlet port and an exit port. The fan additionally has an impeller disposed within the housing. The impeller draws air into the inlet port, accelerates the air, and discharges the air through the exit port. The efficiency matching device is shiftably carried within the exit port for selectively varying the area of the exit port such that the efficiency of the centrifugal fan can be varied to match the output efficiency of the fan to the desired air mass flow through the air delivery system.
