Abstract
A fan array vibration control system may include a fan array having a plurality of fans, and a control unit operatively connected to the fans. The control unit is configured to operate the plurality of fans and detect a phase relationship among the plurality of fans. The control unit is configured to reduce the phase relationship among the plurality of fans in order to reduce vibrations within the fan array.
Claims31
A fan array vibration control system comprising:
- a fan array having a plurality of fans;
- a control unit operatively connected to the plurality of fans, wherein the control unit is configured to detect a phase relationship among the plurality of fans, and wherein the control unit is configured to adjust the phase relationship among the plurality of fans in order to reduce vibrations with the fan array;
- and
- at least one mass-location sensor configured to detect a location of a mass concentration of at least one of the plurality of fans, wherein the control unit is configured to be in communication with the at least one mass-location sensor, and wherein the control unit is configured to detect the phase relationship among the plurality of fans through the at least one mass-location sensor.
1 more element
A method of controlling vibrations within a fan array having a plurality of fans, the method comprising:
- monitoring a phase relationship among the plurality of fans with a control unit, wherein the monitoring operation comprises detecting a location of a mass concentration of each of the plurality of fans with at least one mass-location sensor;
- adjusting the phase relationship among the plurality of fans with the control unit;
- and
- controlling vibrations within the fan array through the adjusting operation.
