Summary:When configuring a heat exchange ventilator that includes a supply air duct that takes in outdoor air and blows it out indoors, an exhaust air duct that takes in indoor air and blows it out outdoors, and a plurality of heat exchange elements that exchanges heat between outdoor air flowing down through the supply air duct and indoor air flowing down through the exhaust air duct, the heat exchange elements being arranged in series from an outdoor side to an indoor side, the sensible heat exchange efficiency of a heat exchange element arranged on the most outdoor side is made higher than the sensible heat exchange efficiency of a heat exchange element arranged on an indoor side adjacent to the heat exchange element arranged on the most outdoor side, or the latent heat exchange efficiency of the heat exchange element arranged on the most outdoor side is made lower than the latent heat exchange efficiency of the heat exchange element arranged on an indoor side adjacent to the heat exchange element arranged on the most outdoor side, thereby preventing condensation and freezing on the heat exchange element on the outdoor side.
