The air is blown out vertically from the vertical outlet toward the bottom of the room, and travels downward while being diffused into the cold air inside the room. This prevents warm outside air from accumulating above the room and causing temperature differences in the vertical direction inside the room. In addition, if the outside air to be supplied is colder than the indoor air, the damper closes the ventilation path of the vertical outlet and opens the ventilation path of the horizontal outlet, allowing the cold outside air to flow from the horizontal outlet to the ceiling. The air is blown horizontally upwards into the room along the surface, and then falls downward while being diffused into the warm air inside the room, preventing direct exposure to cold outside air, and further reducing the difference between the outside air being supplied and the air inside the room. If the temperature difference between the The air is blown vertically downward from the outlet and is uniformly diffused into the indoor air, improving air supply efficiency.
