Abstract

A heat exchange ventilator includes a plurality of heat exchanger elements provided with a heat-exchanger exhaust airflow path and a heat-exchanger intake airflow path. Exhaust airflow and intake airflow are guided to pass through one of the plurality of heat exchanger elements, and the exhaust airflow and the intake airflow are switched to the next heat exchanger element in a sequential order when a state of the heat exchanger element comes to a predetermined condition set based on adverse influences of ice formation inside a heat-exchanger exhaust airflow path. The structure prevents the heat exchanger element from icing to avoid the adverse influences, thereby making it capable of exerting the fundamental heat exchanging and ventilating function continuously.
