Airconditioning generation system capable of solving unbalanced phase and method for the same

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.

Field of the Invention [0002] The present invention relates to an airconditioning generation system capable of solving an unbalanced phase and a method for the same, and more particularly to an airconditioning generation system capable of solving an unbalanced phase and a method for the same, which can prevent the occurrence of an unbalanced phase of a power-supply signal applied to a plurality of outdoor units connected to a plurality of indoor units due to a difference in load. [0003] 2. Description of the Related Art [0004] It is necessary for a driving power-supply signal to drive electrical devices for use in households or factories. Generally, the above-mentioned electrical devices have been designed to receive necessary power-supply signals from a commercial power source provided from the Korea Electric Power Corporation (KEPCO).

Benefits of technology

[0018] Therefore, the present invention has been made in view of the above problems, and it is an object of the invention to provide an airconditioning generation system capable of solving an unbalanced phase and a method for the same, which can prevent the occurrence of an unbalanced phase in a generation system capable of providing an airconditioner with a three-phase power-supply signal, such that they prevent the occurrence of a malfunction or damage of a manufactured product due to the unbalanced phase, and increase product reliability.

[0019] It is another object of the invention to provide an air-conditioning generation system for greatly increasing its power factor and a method for the same, which detect an amount of a current signal applied to individual airconditioners to prevent the occurrence of an unbalanced phase, determine the presence or absence of the unbalanced phase, and change power-supply wiring arrangement of individual airconditioners according to the determined result associated with the unbalanced phase.

[0024] The airconditioning generation system includes a distribution unit capable of detecting individual-phase power values consumed by the indoor units, and changing a wiring structure of a phase power-supply signal transmitted from the generator to the outdoor units. If the unbalanced phase occurs in the three-phase power-supply signal, the airconditioning generation system automatically solves the unbalanced phase, such that it prevents a product from being damaged, and increases product reliability.

[0025] Also, if the unbalanced phase occurs in the three-phase power-supply signal, the airconditioning generation system changes a wiring structure of individual-phase power-supply signals to establish three-phase equilibrium, improves power factor, such that it reduces power consumption of an overall system and costs thereof.

Problems solved by technology

However, if a plurality of indoor units and a plurality of outdoor units are installed in households or factories, it may be difficult for the commercial power-supply signal received from an external part to be sufficiently applied to all driving loads of the indoor and outdoor units, such that a large number of households or factories may frequently use additional self-generation systems, respectively.

However, if loads connected to individual phase power-supply signals have different magnitudes, there is an unexpected difference in an amount of a current signal applied to individual phase power-supply signals, such that the above-mentioned phase equilibrium is broken, and the current signal flows in the N line.

If the current signal flows in the N line as described above, a potential of the N line is increased such that a controller for controlling the airconditioning generation system may malfunction.

If an excessive current signal flows in a one-phase line or a two-phase line due to the unbalanced phase, a compressor contained in each of the generator, the indoor units, and the outdoor units is overheated, such that the compressor may be damaged or a microprocessor of the generator 40 may incur a malfunction or a faulty operation, resulting in the occurrence of a malfunction of the airconditioning generation system, and endurance deterioration thereof.

The user cannot use the above-mentioned airconditioning generation system at all locations of a building or factory equipped with the system until the unbalanced phase is removed, resulting in greater inconvenience of the user and reduction of product reliability.
