ABSTRACT:
A stairwell, in a split or multi level home provides access to and air communication with lower-level, mid-level and upper-level rooms, resulting in a chimney effect of continuously drawing higher temperature and highest temperature room air from the lower-level room. Vertically directed downward axial fans of a room-air interceptor device, emplaced in the lower-level room at its ceiling and at its entrance to the stairwell, not only eliminates such chimney effect; but also intercepts and recirculates temperature-layered room air in the lower-level room, resulting from gravity circulation, to dissipate such temperature-layered room air to render the room air temperature in the lower-level room more uniform and, hence, more comfortable for human habitation and enjoyment.
