Abstract
A totally integrated ventilation system is contained in the outside air inlet stream. The system samples and controls ventilation airflow as it enters a structure. An air valve connecting the outside air inlet stream to the return plenum is controlled by a valve positioning device and a processor that monitors sensors located in the outside air inlet stream, air quality data provided by a telecommunications link and the HVAC system control signals. The air quality data includes locally broadcast air pollution data or air quality alert data related to accidents or terrorist attacks. The processor and valve positioning device simultaneously control a separate pressure relief valve that allows contaminated air to be exhausted from the structure. An alternate configuration uses a supplemental fan to introduce the outside air inlet stream directly into the structure where HVAC systems are not used. A status and control panel that provides an interface to the occupants or an automation system is provided along with a test box that can monitor the processor to determine the total volume of ventilation air introduced into the structure. This test data is used to program processor timing inputs to achieve desired ventilation results.
