The airconditioning generation system includes one or more indoor units (111, 112, 113, 121, 122, 131, 132, 133), one or more outdoor units (110, 120, 130), a generator (70) for providing the indoor and outdoor units with a power-supply signal, and a distribution unit (80, 80?) for detecting an individual-phase power value consumed by the indoor units, changing a phase of the power-supply signal transmitted from the generator (70) to the indoor or outdoor units, and establishing three-phase equilibrium. Therefore, if an unbalanced phase occurs in the three-phase power-supply signals applied to an airconditioner, the system solves the unbalanced phase, such that it prevents a product from being damaged and increases product reliability.
