PROBLEM TO BE SOLVED: To increase the cultivation area in a facility horticultural space and to reliably take in outside air and inside air in an air conditioner. SOLUTION: An air conditioner 1 is arranged outside a facility gardening space G and performs at least one of heating, cooling, humidification, dehumidification, carbon dioxide supply, ventilation, and air flow in the facility gardening space G. A machine body (heater body 2), a suction means (suction fan 3) for sucking air to be supplied to the air conditioner body, an outside air intake port 6c for sucking outside air A1 by the suction means, and a suction means By means of which the inside air intake port 6d for sucking the inside air A2, a position that covers the outside air intake port 6c (first position P1) and a position that covers the inside air intake port 6d (second position P2) are movable. And a member (damper portion 4).
