PROBLEM TO BE SOLVED: To provide an air conditioning device which can perform humidification. SOLUTION: A moisture removing means 12 and a moisture supply means 13 are provided to an aqueous solution circuit 20 which is interposed by a using side heat exchanger 11 made of a porous hydrophobic film which transmits vapor but not liquid. A heat source side first heat exchanger 4 provided to a refrigerating circuit 7 having a compressor 1 which is driven by a gas engine 2, functions as a condenser for refrigerant at the time of heating operation. Lithium bromide water solution which has been heated by the heat exchanger 4 while depriving condensation heat from the refrigerant and has lowered water solubility is sent to the using side heat exchanger 11. A blower 22 is arranged such that room air is blown to the outside of the using side heat exchanger, and therefore the lithium bromide water solution is deprived of its heat and moisture by the room air, thereby simultaneously performing heating and humidification of the room air. The lithium bromide water solution which has lost heat and moisture at the using side heat exchanger 11 enters into an exhaust gas heat exchanger 8 to recover exhaust gas heat of the gas engine 2, further enters a tank 14 of the moisture supply means 13 so as to be moisturized, and supplied to the using side heat exchanger 11. |
