PROBLEM TO BE SOLVED: To provide an air conditioner with improved temperature/humidity controllability by expanding the control range of the temperature/humidity to easily achieve a target temperature/humidity. SOLUTION: The air conditioner comprises a refrigerating cycle in which compressors 1a and 1b, heat exchangers on the heat source side 2a and 2b, beam limiting devices 3a and 3b and heat exchangers on the use side 4a and 4b are connected in the order, refrigerating cycle devices A and B with heat source side blowers 6a+7a and 6b+7b, and use side blowers 8a+9a and 8b+9b, and control means 10a and 10b for variably controlling capacity variable elements such as the compressors in the refrigerating cycle devices A and B. The control means 10a controls the capacity variable elements to make the refrigerating cycle devices A and B operate with different enthalpies so that the temperature/humidity is closer to the target temperature/humidity than the case when the refrigerating cycles A and B are operated with the equal enthalpy so that the total enthalpies are equivalent to the total enthalpies of the refrigerating cycle devices A and B.
