Abstract
There is described a method for controlling an exhaust system having at least two fans, a plenum chamber interconnecting the at least two fans, and a bypass air damper in the plenum chamber to allow bypass air to flow therethrough, the method comprising: monitoring pressure in the plenum chamber of the system; detecting a variation of the pressure beyond a predetermined range; and regulating operation of the exhaust system in response to the pressure variation in order to return the pressure to within the predetermined range.

A method for controlling an exhaust system having at least two fans, a plenum chamber interconnecting said at least two fans, and a bypass air damper in said plenum chamber to allow bypass air to flow therethrough, the method comprising:
- monitoring pressure in said plenum chamber of said system;
- detecting a variation of said pressure beyond a predetermined range;
- and
- regulating operation of said exhaust system in response to said pressure variation in order to return said pressure to within said predetermined range.
An exhaust system assembly comprising:
- at least two fans;
- a plenum chamber having a bypass air damper therein for bypassing air, said plenum chamber interconnecting said at least two fans and having a pressure sensor therein for sensing and detecting a pressure;
- and
- a control module receiving said pressure detected in said plenum chamber and adapted to regulate operation of said at least two fans when said pressure has varied beyond a predetermined range in order to restore said pressure to within said range.
In a computer network enabling communication between a plurality of computers, a method comprising:
- providing at least one sensing device in a fan exhaust system;
- monitoring at least one parameter of said system using said at least one sensing device;
- comparing said at least one parameter to a predetermined tolerance level;
- and
- sending an alarm signal through said network to a remote computer when said at least one parameter does not meet said predetermined tolerance level.
