ELECTROACTIVE SMART HVAC VENT REGISTER

摘要

An electroactive register is shown configured to modulate the incoming airflow in an HVAC duct to form two localized airflows: a first a high-speed airflow to form a conical air curtain surrounding an occupant and limiting air exchange between inside air and air outside of the air curtain, and a second a low-speed airflow (also referred to as center air) inside the air curtain to cool or heat the occupant comfortably. The temperature gradient between inside and outside of the air curtain enables expansion of set points of HVAC. The electroactive register is also able to improve personal comfort as the center air FLS can be customized for each individual occupant.

主权项

1. An electroactive airflow distribution apparatus for HVAC, comprising:
a housing; said housing being in fluid communication with an HVAC duct; plurality of electrically actuated tubes disposed in said housing; said tubes having an aperture configured for receiving airflow from the duct and directing said airflow outward toward an external location with respect to the duct; and said electrically actuated tubes being responsive to an electric signal such that the electrically actuated tubes change shape to modify the outward airflow delivered to the location.
