The purpose of the present invention is to provide an air blowout apparatus such that it is possible to ensure the stable volume of blowout air even if the airflow formed within a duct is either in a first state or in a second state. A first airflow (F1) flows between a first airflow deflection member (13) and a first wall (121), and a second airflow (F2) flows between the first airflow deflection member and a second wall (122). The first airflow deflection member performs switching between a first state in which the speed of the first airflow is higher than that of the second airflow and a second state in which an airflow different from that in the first state is formed. A guide wall (14), which is the portion of the first wall towards the blowout port side, bends the first airflow in the first state along the wall surface and guides the first airflow to the first wall from the second wall. A second airflow deflection member (15) is located downstream from the first airflow deflection member in the air flow direction. The second airflow deflection member deflects the second airflow in the first state toward the first wall from the second wall. The second airflow deflection member makes the degree of deflection of the second airflow toward the first wall from the second wall in the second state lower than in the first state, or prohibits the deflection of the second airflow toward the first wall from the second wall.

Based on a determination at step 115 as to whether an intake refrigerant temperature Ts is at least -32°C, and decisions at steps 145 and 150, either a normal operation or a speed control operation is performed. From a state where the intake refrigerant temperature Ts is less than -34°C, which is when a speed reduction operation is performed, if the intake refrigerant temperature Ts reaches at least -32°C but has not previously reached -20°C, a limited speed operation is performed at step 155. During the limited speed operation, a maximum allowed rotational speed of a compressor (11) is limited to a predetermined speed lower than that of the normal operation. Under different circumstances, if the intake refrigerant temperature reaches at least -32°C, the normal operation is performed at step 160.
