The infrared thermometer 40 is disposed on any one of the first air deflectors 10 to detect the temperature value in the room and the area corresponding to each temperature value. The controller controls the first air deflector 10 opposite to the refrigerant inlet 31 to slide along the circular ring-shaped track 11 according to the highest temperature detected by the infrared thermometer 40 and the area corresponding to the highest temperature, so that the air outlet of the air deflector assembly corresponds to the highest temperature in the room and blows directly, and the air outlets of the other air deflector assemblies can supply air to other positions in the room for refrigeration.
