Abstract
A fan assembly includes a first fan, a second fan, and a controller. The controller is configured to determine that an air movement demand corresponds to operation of the first fan and the second fan at a resonance speed, instruct the first fan to operate at a first speed which is less than the resonance speed, and instruct the second fan to operate at a second speed which is greater than the resonance speed.
Claims24
A fan assembly, comprising:
- a first fan;
- a second fan;
- and
- a controller configured to:
- determine that an air movement demand corresponds to operation of the first fan and the second fan at a resonance speed;
- instruct the first fan to operate at a first speed which is less than the resonance speed;
- and
- instruct the second fan to operate at a second speed which is greater than the resonance speed.
A fan assembly controller comprising processing circuitry configured to:
- determine a demand for air movement by a fan assembly;
- determine that the demand for air movement corresponds to operation of a first fan of the fan assembly and a second fan of the fan assembly at a resonance speed;
- instruct the first fan to operate at a first speed which is less than the resonance speed;
- and
- instruct the second fan to operate at a second speed which is greater than the resonance speed.
A fan controller comprising a memory having a non-transitory, computer-readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- determining that an air movement demand corresponds to operation of a first fan of the fan assembly and a second fan of the fan assembly at a resonance speed;
- instructing the first fan to operate at a first speed which is less than the resonance speed;
- and
- instructing the second fan to operate at a second speed which is greater than the resonance speed.
