Abstract: Systems/methods for measuring airstream parameters.

Abstract: Airstream sensor devices, systems, and related methods are disclosed. The sensor devices, systems, and methods are incorporated in heating, ventilation, and air conditioning (HVAC) ducts and plenum spaces for providing data used to monitor, manage, troubleshoot and/or control such systems. In an example embodiment, an airstream sensor device includes a housing and a plurality of sensors disposed on the housing. The plurality of sensors is configured to detect the temperature, airflow, and relative humidity of an airstream passing on, over, or through the device.

Abstract: A system for providing outside air to a space for dilution of contaminants within the space. The system includes an air handler that supplies a flow of outside air to the space and an occupancy detector that calculates the occupancy of people in the space. Also included is a processor that determines a flow rate set point for the outside air for the space based on the occupancy in the space, the floor area of the space, and the flow of outside air supplied by the air handler. An air flow controller is provided that modulates the air flow from the air handler to the space. An open protocol network is connected to the air handler, the occupancy detector, and the air flow controller, and the processor dynamically calculates the outdoor air flow rate set point.
