Dynamic control of dilution ventilation in one-pass, critical environments
First Claim
1. A dilution ventilation control system for use in a one-pass, critical environments comprising:
- one or more one-pass, critical environments comprising, a variable source of supply airflow volume, a means for completely exhausting said airflow volume supply from said critical environment and from a building comprising said critical environment through one or more exhaust ducts; and
at least one airflow control device provided in one or more of said ducts to vary the exhaust airflow volume from said critical environment;
a facility monitoring system comprising at least one air contaminant sensor for sensing at least one air contaminant of said critical environment;
a signal processing controller that generates one or more airflow command signals based at least in part on at least one sensed air contaminant; and
a critical environment airflow controller that uses said airflow command signal to at least partially control said critical environment'"'"'s supply and exhaust airflow volumes.

72. A method for varying the dilution ventilation airflow volume in a one-pass, critical environment provided with a variable source of supply airflow volume, which is completely exhausted from said critical environment and from the building containing said critical environment through one or more exhaust ducts, at least one of which contains an airflow control device to vary an exhaust airflow volume from said critical environment comprising:
-
monitoring at least one air contaminant of said critical environment by at least one air contaminant sensor to create at least one air contaminant measurement;
creating an airflow command signal using at least one of said air contaminant measurements; and
controlling said critical environment'"'"'s supply and exhaust airflow volumes at least partially using said airflow command signal. - View Dependent Claims (73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131)
