Abstract

An energy recovery ventilator door assembly includes an exterior door for a structure, the door including an inside fan and an outside fan for providing flows of air to a manifold. The manifold includes an inside manifold conduit for receiving stale inside air and an outside manifold conduit for receiving fresh outside air. A heat sink between the two conduits recovers heat energy from the warmer flow of air flowing in the conduits and transmits the recovered heat energy to the cooler of the flows of air in the conduits. A crossover element routs the inside conduit from the inside of the door to the outside of the door, and routs the outside conduit of the door to the inside of the door. Thus the air in the inside manifold conduit is vented to the outside of the structure through the door and the air in the outside manifold conduit is vented to the inside of the structure through the door.

Dependent claims

A ventilator door assembly for recovering heat energy secured to a structure comprising in combination:

a door having a pair of spaced apart stiles and a top rail and a bottom rail appropriately secured together to define a frame;
an inside panel secured to the frame and an outside panel secured to the frame;
a manifold section disposed between the inside and outside panels having an inside manifold conduit through which an inside flow of air flows to an outside of the door through an opening in the outside panel and an outside manifold conduit through which an outside flow of air flows to an inside of the door through an opening in the inside panel;
at least a single fan for providing flows of air for the inside and outside manifold conduits;
a heat transfer element disposed between the inside manifold conduit and the outside manifold conduit for transferring the recovering heat energy from a first flow of air from one of the inside or outside manifold conduits and transferring the recovered heat energy to a second flow of air in the other of the inside or outside manifold conduits;
and
both the first air flow and the second air flow are modified by the recovered heat energy.
