Abstract

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, an exhaust for completely exhausting the airflow volume supply from the critical environment and from a building comprising the critical environment through one or more exhaust ducts; and at least one an airflow control device provided in one or more of the ducts to vary the exhaust airflow volume from the critical environment; a facility monitoring system comprising at least one air contaminant sensor for sensing at least one air contaminant of the 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 the airflow command signal to at least partially control the critical environment's supply and exhaust airflow volumes.
