Abstract:
A system and method for intelligent management of an array of fans. The system uses mean-time-between-failure, fan usage and other data in add ventilation, subtract ventilation and recycle array routines to maximize the life of the fans and the array. The system comprises a primary embodiment making use of smart fans in the array, each smart fan including a fan and appropriate control electronics capable of processing commands received from a smart fan array controller. Fan control signals are multiplexed over a local operating network power line using carrier communication protocols, command messages and data values, all to accomplish a goal of the system to maximize fan life. In an alternate embodiment, fan and array control electronics are integrated onto the fan array controller itself and power is provided to conventional fans using a conventional wiring harness.
