An energy recovery ventilation system improving a fluid passage structure is provided to achieve air flow through the entire length of a heat exchanger by using a plurality of guide units and removing dead zones having no heat transfer, thereby improving heat exchanger efficiency between atmospheric air and room air. An energy recovery ventilation system improving a fluid passage structure includes a duct(110) having an air supply inlet(111) and an air supply outlet(113) for introducing atmospheric air into a room by an air supply fan(115), and an air discharge inlet(121) and an air discharge outlet(123) for discharging room air to the outside by an air discharge fan(125). A heat exchanger(130) is mounted at a side of the duct that is formed with the air supply inlet/outlet and the other side of the duct that is formed with the air discharge inlet/outlet for carrying out heat transfer between the atmospheric air and the room air. A plurality of guide units are formed of a plurality of first guide plates(200) formed with curves at the air supply inlet towards the heat exchanger and a plurality of second guide plates(201) formed with curves at the air discharge inlet towards the heat exchanger, so as to achieve air flow through the entire length of the heat exchanger.
