PROBLEM TO BE SOLVED: To perform temperature/humidity control accurately with high response at the time of conditioning the temperature/humidity of intake outer air while saving energy and reducing cost. SOLUTION: A state change prediction line from an outer air state point to an arbitrary state point on a target temperature/humidity line is set by a prediction line setter 26 onto an air diagram table 21 where a target temperature/humidity line connecting the upper and lower limit state points of conditioning air is set. The state change prediction line comprises a main heating line indicative of the heating operation of a main heater 4, an adiabatic humidification line indicative of the humidification operation of an adiabatic humidifier 5, a cooling line indicative of the cooling operation of a cooler 6, and an auxiliary heating line indicative of the heating operation of an auxiliary heater 7 wherein the end point temperature of each line is set as the target outlet temperature of each temperature/humidity regulator 4-7 which is feedback controlled individually. An alarm signal is delivered from an abnormality detector 28 when the difference between each outlet temperature and target outlet temperature exceeds an allowable error and does not decreases. |
