Generated explanation

The illustration shows a heat recovery ventilator (HRV) connected to furnace ductwork and to outdoor intake and exhaust openings through an exterior wall. Arrows show warm air from the return air duct system entering the HRV and exhaust air leaving outdoors. Outdoor supply air passes through the HRV and enters the furnace return air duct, while the furnace supply air duct carries air toward the heating ducts. Balancing dampers are identified in the two ducts connecting the HRV to the indoor duct system. An annotation explains that the HRV transfers heat from warm return air to cool outdoor supply air.
