PROBLEM TO BE SOLVED: To provide a desiccant air-conditioning unit capable of preventing performance deterioration, reducing electrical power consumption of an air supply fan, and using natural energy for cooling/heating ambient air.SOLUTION: A desiccant air-conditioning unit 31 comprises: desiccant rotors 40 and 41 for dehumidifying air; cooling coils 42 and 43 for cooling the air humidified by the desiccant rotors 40 and 41 with cooling water generated in a cooling tower 46; heating coils 56 and 57 for heating return air RA for reproducing dehumidification agent, which contains water due to air dehumidification, in the desiccant rotors 40 and 41; and a humidifier 44 in which, during humidification, supply air SA to be supplied to an air-conditioning objective space is enabled to be humidified in the desiccant rotor 41 after being heated in the heating coil 57 while the humidifier 44 supplies humidification water to air humidified by the desiccant rotor 41. The desiccant air-conditioning unit 31 reproduces the desiccant rotor 41 by the return air RA heated in the heating coil 56. |
