louvers louvers microprocessor 135 will communicate a component failure alarm (not shown). - In further accordance with an exemplary embodiment, in the event that
microprocessor 135 receives, through hazardous gasdetection system input 154, that hazardous gas has been detected insystem enclosure 2, inblock 230, first, second, and/orthird motor air circulating devices block 250.Microprocessor 135 also signals first, second and third damper controls 62, 72 and 84 to fully open corresponding ones of first, second and third pluralities oflouvers system enclosure 2. An alert, visual and/or audible, is output inblock 252. First, second, and/orthird motors air circulating devices louvers - At this point it should be understood that the t ventilation monitoring system, in accordance with the exemplary embodiments, adjusts damper position to control ventilation flow based on at least one of air circulating device speed input and internal enclosure temperatures. The ventilation monitoring system may interface with other turbomachine controls to enhance ventilation, as desired, and to operate air circulating devices intermittently at the higher speeds only when necessary. For example, ventilation monitoring system may adjust ventilation flow to maintain desired clearances in the compressor portion and/or the turbine portion. Further, the ventilation monitoring system also interfaces with a hazardous gas detection system to evacuate the system enclosure in the event hazardous gas is detected. Further, the ventilation monitoring system may maintain desired temperatures within the enclosure. For example, the ventilation system may interface with a turbomachine control system and plant distributed control system (DCS) to maintain the enclosure temperature within a predetermined range and, if desired, assist in reducing cool down time for machine in preparation for maintenance.

Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
