Abstract

An air conditioning apparatus and control method thereof includes an inverter-type compressor and a two-stage variable-capacity compressor connected in parallel with their respective capacities controlled according to indoor air conditioning loads. Thus, the present invention is cost-competitive due to a capacity of the inverter-type compressor being lower than that of the two-stage variable-capacity compressor.
