When the control unit 17 determines that the indoor temperature is lower than the outdoor temperature, the first partition 13 is opened and the second partition 14 is closed. The indoor air and the outdoor air exchange heat with each other while passing through the heat exchange element. That is, the air entering the room from the outside is cooled, and the air exiting the room from the room is heated.
