Abstract

An airconditioning generation system capable of solving an unbalanced phase, and a method for solving the unbalanced phase are disclosed. 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.
