By installing them spaced apart along the circumference, the air in the cultivation room can be more uniformly circulated as a whole, and the hot air in the cultivation room can be assisted to be discharged through the exhaust duct 72.

Therefore, when the air temperature in the cultivation chamber exceeds the reference value by the temperature sensor, the exhaust part 70, the air supply part 80, and the circulation fan 90 are operated in conjunction, so that overall convection may occur in the cultivation chamber. The hot air in the cultivation room is quickly discharged, so that the temperature of the air in the cultivation room can be uniformly managed overall. In addition, since outside air can be introduced through the air supply unit 80, the concentration of carbon dioxide in the cultivation room can be easily managed so that it is generally uniform, so that the transpiration of the tomato 1 can be evened out and the tomato 1 can can grow evenly. Such an air conditioning unit is temporarily operated only when the air temperature in the cultivation room rises, and since the air temperature in the cultivation room can be uniformly managed overall by the air conditioning unit, an energy reduction effect can be expected.

On the other hand, the stem of the tomato 1 can be directly shaken by the convection phenomenon generated in the cultivation room by the air conditioning unit, so that the self-fertilization rate of the tomato 1 can be improved.
