A heat-exchange type ventilation apparatus (1) has a heat-exchange element (11) disposed in a position where an air-supply blower channel (6) and an exhaust blower channel (7) intersect. The heat-exchange type ventilation apparatus (1) is also provided with an air-channel shield (12), an in-room humidity meter (13), and a controller (28). The controller (28) is provided with an exhaust operation mode for reducing the introduction of outside air (24) to the heat-exchange element (11) when the value of the in-room humidity meter (13) exceeds a first predetermined value. |
