Abstract
An active airflow inhibiting apparatus for an entranceway comprises a structure, an airflow sensor, and a controller. The structure comprises one or more air mover devices configured to be positioned adjacent an entranceway of a building and defining a passage therethrough for accessing the entranceway. The airflow sensor is configured to provide an output indicative of speed and direction of airflow through the entranceway or at the air mover devices. The controller is connected to the air mover devices and the airflow sensor. The controller is configured to receive the output of the airflow sensor and to control an output of the air mover devices based on the received output so as to generate a differential pressure across the air mover devices which inhibits airflow through the entranceway.
Claims15
An active airflow inhibiting apparatus for an entranceway comprising:
- a structure comprising an air mover device configured to be positioned adjacent and spaced apart an entranceway of a building and defining a passage therethrough for accessing the entranceway;
- an airflow sensor configured to provide an airflow output signal, the airflow output signal indicative of a speed and a direction of airflow through the entranceway or at the air mover device;
- a controller connected to the air mover device and the airflow sensor;
- wherein the controller is configured to receive the airflow output signal of the airflow sensor and to control an airflow output of the air mover device based on the received airflow output signal so as to generate a differential pressure across the air mover device which inhibits airflow through the entranceway;
- and
- wherein the air mover device is an air multiplier device and forms an archway.
