Abstract
A damper blade is moved within an air control module connected to the discharge of a high-velocity blower, thereby modulating the electric power consumption of the blower motor.
Claims11
A method for mechanically modulating electric power consumption of a blower motor associated with a ventilation unit, said method comprising:
- determining in a processor a volumetric airflow requirement based on sensor data and on at least one control signal related to the sensor data;
- selecting for a damper blade associated with said ventilation unit a modulated flow position corresponding to the volumetric airflow requirement;
- generating in said processor a command signal corresponding to the modulated flow position;
- and
- adjusting said damper blade in response to the command signal, thereby modulating electric power consumption of said blower motor.
2 more elements
A noise-reducing air control module apparatus comprising:
- a casing enclosing a passage for high-velocity airflow;
- a damper blade movable within said casing for varying a flow area of the passage enclosed by said casing, the broadest surface of said damper blade having a generally rectangular shape with at least one rounded corner, the at least one rounded corner defining a removed area such that, with said damper blade positioned generally across the passage enclosed by said casing, said damper blade obstructs no more than about eighty-four percent (84%) of the flow passage;
- a processor configured to receive sensor data and to generate a command signal based on parameters including at least the received sensor data and at least one control signal related to the received sensor data;
- and
- an actuator in communication with said processor and operably connected between said damper blade and said casing for adjusting said damper blade to vary the flow area of the passage in response to the generated command signal,
- wherein the command signal represents a modulated flow position of said damper blade selected from a range of positions between a maximum-flow position and a minimum-flow position.
