PURPOSE: A ventilation system is provided to widen an area contacting with the air by making a gap forming unit of a heat exchanging element in various shapes. CONSTITUTION: A ventilation system is composed of an external air suction port formed at one side of a body case to suck in the external air; an external air supply fan(150) for blowing forcibly the air sucked through the external air suction port into the room; an external air delivery port(82) formed at the other side of the external air suction port to be an outlet for ejecting the air sent from the supply fan into the room; a room air suction port(88) disposed on one side of the body case to be an inlet for sucking in the room air; a room air exhaust fan(100) for blowing the air passing through the room air suction port to the outside; a room air discharge port arranged on one side of the body case to be an outlet for discharging the room air to the outside; and a heat exchanger(60) for exchanging heat between the external air inserted through the external air suction port and the air input through the room air suction port and composed of heat exchanging elements layered plurally. The heat exchanging elements are made from conductive plastic with good heat transfer efficiency.
