Abstract
A defrost airflow assembly for a heating, ventilation, and air-conditioning (HVAC) case, having a defrost channel starting in a mixing chamber and terminating in a defrost outlet with a defrost door, a demist channel starting in the mixing chamber and terminating in a demist outlet with a demist door, and a bypass channel connected directly with the post-door defrost channel and the post-door demist channel, and indirectly with the pre-door demist channel and the pre-door defrost channel. The first bypass channel is configured to allow airflow from the mixing chamber to the defrost outlet when the defrost door is in the closed position and the demist door is in the open position.
