PROBLEM TO BE SOLVED: To prevent the solidification of liquid absorbent in an absorbent circuit while a humidity controller stops operating in relation to the humidity controller for controlling the humidity of air using the liquid absorbent.SOLUTION: A drive temperature is set to a temperature higher than a solidification point of liquid absorbent calculated based on liquid-absorbent concentration detecting means (14). If a temperature of the liquid absorbent detected by temperature detecting means (16) is equal to or lower than the drive temperature while a humidity controller stops operating, a solidification prevention operation for actuating a circulation pump (12) and circulating the liquid absorbent in an absorbent circuit (11) is performed. |
