Abstract:
A heat exchanging ventilation device is provided with: an air supply blower (2) which generates a supply air flow; an air discharge blower which generates a discharge air flow; a heat exchanger which exchanges heat between the supply air flow and the discharge air flow; a housing having a first plate section in which a supply air inlet and a discharge air outlet are provided, and a second plate section in which a supply air outlet and a discharge air inlet are provided, the housing having formed therein a supply air passage which is a passage for the supply air flow which flows from the supply air inlet through the heat exchanger toward the supply air outlet, the housing also having formed therein a discharge air passage which is a passage for the discharge air flow which flows from the discharge air inlet through the heat exchanger toward the discharge air outlet, the housing further having formed therein a bypass passage which is a flow passage for the discharge air flow which flows from the discharge air inlet through the outside of the heat exchanger toward the discharge air outlet; and a damper (40) which is a switching section held by the air supply blower and switching between a flow passage leading from the discharge air inlet toward the heat exchanger and the bypass passage.
