  • HVAC temperature stratification improvement technique
    Patent number: 9587850
    Abstract: An air distribution door for use in a ventilation system with anti-stratification feature is provided. The door includes a tab extending from the main body of the door. The tab partially disrupts air flow going into the heat exchanger. This disruption slows high velocity airflow going across the heat exchanger and causes a more uniform thermal transfer distribution to the air from the heat exchanger, which provides preferred comfort by the user.
    Type: Grant
