PROBLEM TO BE SOLVED: To provide an air conditioner for easily performing dehumidifying and air conditioning for a desired area in a protected horticulture greenhouse. SOLUTION: This heat pump-type air conditioner 3 for a protected horticulture greenhouse, performing heating, cooling and dehumidifying of the inside of the protected horticulture greenhouse includes a case frame 3a, a compressor 14 set in the case frame, a condenser 4 and a vaporizer 5. Air in the greenhouse is led to the condenser with a condenser fan 8, heat-exchanged to become hot air, and blown out from a hot air duct 6 to outside the case frame. Furthermore, air in the greenhouse is led to the vaporizer 5 with a vaporizer fan, heat-exchanged, dehumidified, cooled, and blown out from a cold air duct 7 to outside the case frame. The ducts 6 and 7 are each made expandable and contractable, and changeable in direction so as to lead cold air dehumidified and cooled with the vaporizer and hot air heated with the condenser to a desired direction in the greenhouse.
