Also, the indoor air introduced into the second suction port 52 passes through the heat exchange element 60 . The indoor air passing through the heat exchange element (60) is discharged to the outside through the second outlet (54). The flow path follows the second flow path. Here, the first flow path and the second flow path form an X-shaped flow path as a whole. The heat exchange element 60 is disposed at an intersection of the first and second flow passages. The heat exchange element (60) is disposed so that the square corner is adjacent to the inner wall of the indoor space of the device body (50).
