PROBLEM TO BE SOLVED: To control a unit to be controlled at a temperature and humidity suitable for operation of the unit to be controlled in a low-temperature low-humidity environment by air conditioning, without forming dew on the unit to be controlled.SOLUTION: An air conditioner 3 supplying an air-conditioned airflow to a unit 1 to be controlled includes a temperature controller 31, a humidifier 32, and an air-conditioning control device 33. The air-conditioning control device 33 controls the temperature controller 31 and the humidifier 32 so that absolute humidity of te airflow may not exceed a saturated water vapor amount A in a temperature of the unit 1 to be controlled, on the basis of a temperature of the unit 1 to be controlled detected by a temperature sensor 6, humidity around the unit 1 to be controlled detected by a second humidity sensor 52 and humidity of the airflow detected by a first humidity sensor 51 (S106, S107, S108). |
