<p>A METHOD AND APPARATUS FOR MAINTAINING ROOM AIR CHARACTERISTICS IN AN AIR VENTILATED FACILITY USING FAN FILTER UNITS A system for maintaining at least one air characteristic in an air ventilated facility using at least one fan filter unit (207), the system comprising at least one sensor (209) for sensing the at least one air characteristic, the at least one sensor (209) being exposed to the air ventilated facility; the at least on~ sensor (209) being operatively connected to a control system (212) that is operatively connected to the at least one fan filter unit (207); the control system (212) receiving output readings from the at least one sensor (209) and determining if the output reading is within a range C3nd, in response to a negative determination, providing a command to the at least one fan filter unit (207) to adjust the at least one fan filter unit operating speed. Acorresponding method and apparatus are also disclosed. Figure 2</p> |
