Series fan speed control system |
摘要 |
A redundant fan system includes an in-series configuration of adjustable speed fans. A speed controller coupled to the fan system includes a first fan operated at a constant operating speed and a second fan operated at an adjusted operating speed to maintain a speed differential between the first and second fan speeds. A sensing device is connected to the first and second fans and to the speed controller for maintaining the speed differential constant.
