換気扇。In an air conditioning ventilation fan equipped with an indoor air exhaust passage, an outdoor air suction passage, and a heat exchanger that indirectly exchanges heat between the indoor air and outdoor air flowing through these passages, changes in air pressure in the indoor air exhaust passage a detection means for detecting the amount of frost that has adhered to the heat exchanger by detecting the amount of frost formed on the heat exchanger; and indoor air that communicates between the outdoor air intake passage upstream of the heat exchanger and the indoor air discharge passage downstream of the heat exchanger. When the amount of change in the air pressure detected by the circulation passage and the detection means is below a predetermined value, the outdoor air intake passage and the indoor air discharge passage are opened independently, and the indoor air circulation passage is shut off. Ventilation is performed, and if the amount of change in air pressure exceeds a predetermined value, the air inlet of the outdoor air intake passage and the air outlet of the indoor air exhaust passage are closed, and the indoor air circulation passage is opened to allow indoor air to flow out. An air-conditioning ventilation fan characterized by being provided with passage switching means for causing circulation via a heat exchanger.
