PROBLEM TO BE SOLVED: To provide an air conditioning apparatus for a painting booth enabling air-conditioned air to securely reach target temperature and humidity with small energy for a short time.SOLUTION: An air conditioning apparatus 1 for a painting booth includes temperature conditioning means 23, 26, 27, a humidity conditioning means 24 and a temperature and humidity control means 41. The temperature and humidity control means 41 performs control to make temperature and humidity reach a target point P0 of temperature and humidity set on an air line chart 61, and generates air-conditioned air A1. The humidity conditioning means 24 includes a humidification means for humidifying outside air A0 by injecting humidification water W1 and recovering and reusing the humidification water W1. The temperature and humidity control means 41 includes: a temperature sensor 40 measuring water temperature of the humidification water W1; and a target point changing means 42 changing the target point P0 of the temperature and humidity on the basis of the measured value. The temperature and humidity control means 41 adjusts the water amount of the humidification water W1 to make the temperature and humidity reach the changed target point P0. |
